Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of the production and preparation of synthesis ammonia feed gas, and particularly relates to a water gas production system, a production process and a control method. Background Art
[0002] Water gas, as a commonly used synthesis ammonia feed gas at present, is used by various small and medium-sized nitrogen fertilizer plants; however, most of the existing small and medium-sized nitrogen fertilizer plants in the country produce synthesis ammonia by means of intermittent gasification of solid anthracite lump coal or briquette in a fixed bed gasifier. During the gas production process, ordinary air (oxygen content ≤ 21%) or oxygen-enriched air (oxygen concentration 45 - 55%) added with oxygen is generally used to be mixed with water vapor as a gasifying agent and added to the gasifier for gas production. When water vapor decomposes during the reaction with the high-temperature carbon layer, it needs to absorb heat, and the heat released by the oxidation reaction of oxygen and raw coal is used to achieve heat balance. The content of effective gas CO + H2 in the produced feed gas is 55% - 60%. Due to the generally low steam decomposition rate (≤ 45%) in fixed bed coal gasification and large steam consumption; at the same time, a large amount of CO2 is discharged and not utilized during the purification process of the synthesis ammonia feed gas, resulting in energy waste.

Specific embodiments
[0061] The inventive concepts of the present disclosure will hereinafter be described using terms that are commonly used by those skilled in the art to convey the substance of their work to other artisans in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein. These embodiments are provided to make the present disclosure more thorough and complete and to fully convey the scope included to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive.
[0062] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.
[0063] Meanwhile, it should be noted that the term "water gas" in the present invention does not refer to the gas generated by the reaction of water and coal in the conventional sense, but refers to the mixed gas rich in hydrogen and carbon monoxide generated by the reaction of water and organic substances, specifically water and alcohols.
[0064] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0065] Embodiment 1
[0066] Since the production systems in the prior art still use the traditional reaction of water vapor with a high-temperature carbon layer to prepare water gas, not only is the steam decomposition rate relatively low, the steam consumption is large, but also it is easy to pollute the environment. To solve this problem, this embodiment proposes a water gas production system. During the operation of the water gas production system, water and alcohol are used as raw material liquids to prepare water gas; specifically:
[0067] As shown in the Figures 1-4 accompanying drawings, the production system includes an integrated burner 1, a blower, a liquid storage tank 2, a gas collection device 5, and a fuel supply device. The integrated burner 1 internally includes at least a combustion chamber 11, a raw material liquid chamber 12, and a water gas preparation chamber. In the present invention, during the normal operation of the production system, at least a fuel combustion process and a water gas preparation process are carried out inside the integrated burner 1;
[0068] The fuel supply device is connected to the integrated burner 1 and is used to supply fuel to the integrated burner 1 to maintain the combustion process inside the integrated burner 1. The blower is connected to the integrated burner 1 and is used to provide combustion-supporting air for the combustion process. The liquid storage tank 2 is connected to the integrated burner 1 and is used to supplement the raw material liquid into the integrated burner 1 to maintain the water gas preparation process. The gas collection device 5 is connected to the integrated burner 1 and is used to collect the water gas prepared in the integrated burner 1.
[0069] The integrated burner 1 includes:
[0070] The combustion chamber 11 is a cylindrical chamber, providing a combustion space for the combustion process; a combustion outlet pipe 112 is provided on the burner 11 for discharging the flue gas generated during the combustion process of the integrated burner 1. A burner 17 is provided in the combustion chamber 11. The burner 17 is communicated with the fuel supply device and is used for fuel combustion. At the same time, an ignition device is provided on the burner 17 to provide an ignition function. The blower is communicated with the burner 17 through an air pipeline 6 and is used to introduce combustion-supporting air into the combustion chamber 11;
[0071] At least part of the chamber structure in the raw material liquid chamber 12 is an annular chamber, providing a storage space for the raw material liquid; at least part of the chamber structure of the raw material liquid chamber 12 is arranged inside the combustion chamber 11 and / or at least part of the chamber structure of the raw material liquid chamber 12 surrounds and sleeves the outside of the combustion chamber 11. In the case of heat release by combustion in the combustion chamber 11, the raw material liquid in the raw material liquid chamber 12 is heated and evaporated through heat conduction, transfer, radiation, etc. to form raw material steam. The inlet of the raw material liquid chamber 12 is connected to the liquid storage tank 2 through a liquid supplement pipeline 4. A steam outlet 125 is provided on the raw material liquid chamber 12 for discharging the raw material steam generated in the raw material liquid chamber 12;
[0072] The water gas preparation chamber is an annular chamber. The steam inlet 131 of the water gas preparation chamber is communicated with the steam outlet 125 of the raw material liquid chamber 12. And the water gas preparation chamber surrounds and sleeves the outside of the combustion chamber 11, so that the raw material steam can enter the water gas preparation chamber, and the raw material steam is prepared into water gas in the water gas preparation chamber. At the same time, when the combustion chamber 11 burns and releases heat, through heat conduction, transfer, radiation and other ways, heat is provided for the reaction occurring in the water gas preparation chamber; An air outlet interface 151 is arranged on the water gas preparation chamber, and the air outlet interface 151 is communicated with the gas collection device 5. Thus, the water gas prepared by the water gas preparation chamber enters the gas collection device 5 through the air outlet interface 151 for the collection process of water gas.
[0073] Among them, a catalyst is arranged in the water gas preparation chamber, and the raw material steam undergoes a catalytic reaction through the catalyst; For different raw materials, such as a mixture of water and ethanol, a mixture of water and propanol, or a mixture of water and glycerol, etc., the prepared water gas is a mixed gas of water gas, carbon monoxide, and carbon dioxide; In addition, the raw material liquid can also be only alcohols, such as methanol, ethanol, propanol, glycerol, etc., and the prepared water gas is a mixed gas of water gas, carbon monoxide, and carbon dioxide;
[0074] For the catalyst arranged in the water gas preparation chamber, the corresponding catalyst in the prior art is selected according to different raw material liquid components; For example, for a mixture of water and methanol, a copper-based catalyst can be used, and for ethanol, a platinum-based catalyst or a nickel-based catalyst can be used. Since the catalyst and its selection, preparation and other related processes are all prior art, they will not be elaborated here.
[0075] Similarly, for the gas collection device 5, it is a conventional gas collection device in the prior art, such as a gas tank, an airbag and other conventional devices; Corresponding filtering, impurity removal, drying and other structural components can be arranged inside the gas collection device 5 or at the air inlet to perform impurity removal, drying and other treatments on the prepared water gas; Since they are all prior art, they will not be elaborated here.
[0076] In addition, a water gas outlet pipe 51 is arranged on the gas collection device 5, and the water gas outlet pipe 51 is communicated with downstream equipment for supplying the collected and processed water gas components to the downstream equipment for production use.
[0077] As a preferred embodiment, as shown in the appendix Figure 1 As shown, the inside of the liquid storage tank 2 includes at least two chambers, one is a liquid storage chamber and the other is a tail gas chamber. The liquid replenishing pipeline 4 is communicated with the liquid storage chamber of the liquid storage tank 2;
[0078] One end of the combustion outlet pipe 112 is communicated with the combustion chamber 11, and the other end of the combustion outlet pipe 112 is communicated with the tail gas chamber of the liquid storage tank 2. A smoke extractor 21 is arranged on the liquid storage tank 2, and the smoke extractor 21 is communicated with the tail gas chamber for extracting the tail gas generated in the combustion chamber 11. Thus, a heat exchange structure is formed between the liquid storage chamber and the tail gas chamber inside the liquid storage tank 2, so that the tail gas generated in the combustion chamber 11 preheats the raw material liquid in the liquid storage chamber during the discharging process, and the waste heat can be fully recovered and utilized.
[0079] Therefore, in the water gas production system proposed in this embodiment, water and alcohol are used as the raw material liquid, and the combustion process and the water gas production process are carried out simultaneously in the integrated burner 1 to produce water gas, thus solving the problem that the traditional method of reacting water vapor with a high-temperature carbon layer to produce water gas is still used in the prior art. The water gas production system proposed in this embodiment not only has a high steam decomposition rate and a small steam consumption, but also is beneficial to reducing pollutant emissions.
[0080] In addition, for the setting of the chamber positions inside the burner 1, two implementation schemes are proposed in this embodiment:
[0081] Implementation Scheme One: Inside the integrated burner 1, the combustion chamber 11, the raw material liquid chamber 12, and the water gas preparation chamber are sequentially arranged in a surrounding and nested manner from the inside to the outside; this implementation scheme is approximately the same as the structures shown in the attached Figure 3 、attached Figure 7 and other figures;
[0082] Implementation Scheme Two: Inside the integrated burner 1, the raw material liquid chamber 12 and the water gas preparation chamber are arranged adjacent to each other in the vertical direction, and at least part of the chamber structure of the raw material liquid chamber 12 and the water gas preparation chamber are simultaneously sleeved outside the combustion chamber 11; this implementation scheme is substantially the same as the structure in the attached Figure 4 ;
[0083] For Implementation Scheme Two, the raw material liquid chamber 12 can be arranged above or below the water gas preparation chamber.
[0084] Embodiment 2
[0085] Since the catalytic reaction occurring in the water gas preparation chamber usually needs to reach a certain temperature condition to proceed, in this application, a part of the heat is transferred to the water gas preparation chamber by using the combustion process in the combustion chamber 11, so that the water gas preparation chamber can maintain the required reaction temperature condition.
[0086] Therefore, in order to maintain the production process of water gas, the combustion process needs to be maintained in the combustion chamber 11, as shown in the attached Figures 1-3As shown, based on Embodiment 1, this embodiment improves the production system:
[0087] The production system includes a fuel supply device and a fuel pipeline 7. The inlet end of the fuel pipeline 7 is connected to the fuel supply device, and the outlet end of the fuel pipeline 7 is connected to the burner 17, so that the integrated burner 1 can ensure the temperature inside by burning fuel, ensuring that the water gas preparation chamber can be relatively stably maintained within the temperature range required for the catalytic reaction.
[0088] The fuel provided by the fuel supply device is at least one of conventional gaseous fuels, solid fuels, and liquid fuels; among them, gaseous fuels include natural gas, coal gas, biogas, petroleum gas, etc., solid fuels include pulverized coal, carbon powder, solid alcohol, etc., and liquid fuels include methanol, ethanol, gasoline, diesel, crude oil, etc.
[0089] Embodiment 3
[0090] As shown in the appendix Figures 1-5 As shown, based on Embodiment 1 or Embodiment 2, this embodiment specifically introduces the structure of the integrated burner 1.
[0091] The integrated burner 1 further includes a water gas pipeline 8 and a steam pipeline 9. The inlet end of the steam pipeline 9 is connected to the steam outlet 125 of the raw material liquid chamber 12, and the outlet end of the steam pipeline 9 is connected to the steam inlet 131 of the water gas preparation chamber; the inlet end of the water gas pipeline 8 is connected to the gas outlet interface 151 of the water gas preparation chamber, and the outlet end of the water gas pipeline 8 is connected to the gas collection device 5.
[0092] The raw material liquid chamber 12 includes a liquid storage chamber 19 and an evaporation chamber 16 that are connected in sequence from bottom to top. The liquid storage chamber 19 and the evaporation chamber 16 are both annular chambers, and the liquid storage chamber 19 and the evaporation chamber 16 are both sleeved outside the combustion chamber 11; this structure is as shown in the appendix Figure 5 , appendix Figure 7 , appendix Figure 9 and other attached drawings. It should be noted that in this structure, the raw material liquid chamber 12 is a complete chamber, and the raw material liquid accumulates at the lower part of the raw material liquid chamber 12 due to its own gravity. Therefore, in this embodiment, the space occupied by the liquid raw material liquid is regarded as the liquid storage chamber 19; the raw material liquid evaporates when heated, and the formed raw material liquid steam rises. Therefore, in this embodiment, the space occupied by the raw material liquid steam is regarded as the evaporation chamber 16.
[0093] In addition, this embodiment also makes corresponding improvements to the raw material liquid chamber 12. The liquid storage chamber 19 and the evaporation chamber 16 in the raw material liquid chamber 12 are independent chamber structures that are interconnected. The raw material liquid chamber 12 further includes a furnace tube 111b. One end of the furnace tube 111b is connected to the liquid storage chamber 19, and the other end of the furnace tube 111b is connected to the evaporation chamber 16;
[0094] Among them, as shown in the attached Figure 3 , the attached Figure 4 , the attached Figure 11 , the attached Figure 12 shows, the furnace tube 111b can be arranged outside or inside the combustion chamber 11, or the furnace tube 111b is inlaid and connected with the furnace inner wall 111 of the combustion chamber 11; the raw material liquid chamber 12 includes any one of the three ways of arranging the furnace tubes 111b:
[0095] Way 1: The raw material liquid chamber 12 includes one furnace tube 111b.
[0096] Way 2: The raw material liquid chamber 12 includes a plurality of furnace tubes 111b, and the furnace tubes 111b are arranged in a single-layer annular structure; the structure in Way 2 is as shown in the attached Figure 12 shows.
[0097] Way 3: The raw material liquid chamber 12 includes a plurality of furnace tubes 111b, and the furnace tubes 111b are arranged in a multi-layer annular structure, and the furnace tubes 111b in different circumferential directions are arranged staggeredly; the structure in Way 3 is as shown in the attached Figure 4 shows.
[0098] The water gas preparation chamber includes a steam chamber 13, a catalytic chamber 14, and a gas storage chamber 15 that are connected in sequence. A steam inlet 131 is provided on the steam chamber 13 for receiving and accommodating raw material steam. A catalyst is filled in the catalytic chamber 14, and the raw material steam reacts through the catalyst to generate water gas. The gas storage chamber 15 receives and accommodates the generated water gas, and an air outlet interface 151 is provided on the gas storage chamber 15 for leading the water gas out of the gas storage chamber 15.
[0099] A first filter plate 141 is provided between the steam chamber 13 and the catalytic chamber 14, so that the raw material steam in the steam chamber 13 can enter the catalytic chamber 14 more dispersedly and evenly, fully contact with the catalyst, and improve the catalytic reaction efficiency and the water gas output; a second filter plate 142 is provided between the catalytic chamber 14 and the gas storage chamber 15 to filter the air flow to prevent the air flow from carrying catalyst particles out.
[0100] Example 4
[0101] Since the catalyst has good catalytic activity within a certain working temperature range, if the temperature in the catalytic chamber 14 is too high, it may cause the catalyst to be deactivated at high temperature; on the basis of ensuring that the combustion condition and combustion scale in the combustion chamber 11 remain unchanged, as shown in the attached Figures 3-12 shows, in this example, on the basis of any one of Examples 1-3, the chamber structure and its cooperation relationship in the integrated burner 1 are improved.
[0102] A sandwich structure 114 is provided between the water gas preparation chamber and the combustion chamber 11, and the sandwich structure 114 can be provided in one or more layers; an insulation chamber 115 is provided inside the sandwich structure 114, and the steam chamber 13 is communicated with the insulation chamber 115;
[0103] Specifically, the sandwich structure 114 is mainly provided between the catalytic chamber 14 and the combustion chamber 11 for high-temperature protection of the catalyst. The principle of action is as follows: during the operation of the integrated burner 1, a part of the raw material steam entering the steam chamber 13 enters the catalytic chamber 14 for catalytic reaction, and another part of the raw material steam enters the insulation chamber 115, thereby blocking part of the heat in the combustion chamber 11 and avoiding excessive heat in the combustion chamber 11 from being transferred to the catalytic chamber 14, resulting in the inactivation of the catalyst at high temperature.
[0104] Example 5
[0105] As shown in the attached Figures 3-4 figure, a specific implementation scheme is proposed based on Example 4 in this example.
[0106] The furnace body of the integrated burner 1 is enclosed in a cylindrical shape by the housing 10. The housing 10 includes an outer housing 101 and an inner housing 102. The inner housing 102 extends upward to form an arched top surface. Heat insulation or heat-resistant material is filled between the outer housing 101 and the inner housing 102. The outer housing 101, the inner housing 102, and the filled heat insulation or heat-resistant material together form a heat insulation layer 103. The inner center of the integrated burner 1 is set as a combustion chamber 11. The combustion chamber 11 is a cylindrical cavity, enclosed by a furnace inner wall 111 and a furnace outer wall 113.

The first fin 111a faces the side of the furnace inner wall 111. The upper part of the first fin 111a is connected to the furnace inner wall 111, and the lower part of the first fin 111a is connected to the lower part of the furnace inner wall 111.

[0108] It should be noted that the furnace tube 111b in this embodiment is the same as the furnace tube 111b in Embodiment 3 and belongs to Mode 3 in the setting manner of the furnace tube 111b in Embodiment 3. Specifically:
[0109] As shown in the appendix Figures 3-4As shown, in this embodiment, the inner space of the furnace tube 111b belongs to a part of the raw material liquid chamber 12. The furnace tube 111b is arranged in two layers and is respectively connected to the first inner wall 1111 and the second inner wall 1112 to form a double-layer structure.

[0111] The first inner wall 1111 is arranged discontinuously, or there are notches or through holes on the first inner wall 1111, so that the space between the first inner wall 1111 and the second inner wall 1112 is communicated with the combustion chamber 11. Or rather, the space between the first inner wall 1111 and the second inner wall 1112 belongs to a part of the combustion chamber 11. At this time, the furnace tube 111b arranged on the second inner wall 1112, as a structural component of the raw material liquid chamber 12, can be regarded as being completely arranged inside the combustion chamber 11.

The raw material liquid chamber 12 and the evaporation chamber 16 are communicated through a plurality of furnace tubes 111b. Raw material liquid or raw material liquid steam is passed through the middle of the furnace tubes 111b to cool the furnace outer wall 113, prevent the temperature from being too high, and at the same time prevent the catalyst temperature from being too high and losing its activity.

A steam inlet 131 is arranged at the lower part of the steam chamber 13, which is communicated with the steam outlet 125 through a pipeline to introduce the raw material liquid steam discharged from the steam outlet 125 into the steam chamber 13. A first filter plate 141 is arranged at the connection between the bottom of the catalytic chamber 14 and the steam chamber 13 to filter the raw material liquid steam. The filtered raw material liquid steam enters the catalytic chamber 14. The catalytic chamber 14 is filled with a catalyst. The raw material liquid steam reacts under the action of the catalyst to generate water gas. A second filter plate 142 is arranged at the connection between the top of the catalytic chamber 14 and the gas storage chamber 15 to filter the generated water gas and then introduce it into the gas storage chamber 15. An air outlet interface 151 and a second safety port 152 are arranged at the upper part of the gas storage chamber 15. The second safety port 152 is used to connect a pressure switch or a safety valve device of the water gas to ensure the pressure stability of the water gas inside the integrated burner 1.
[0119] Embodiment 6
[0120] As attached Figures 5-6As shown in the figure, another specific implementation is proposed based on Embodiment 4 in this embodiment.
[0121] The furnace body of the integrated burner 1 is enclosed by the housing 10 into a cylindrical shape. The housing 10 includes an outer housing 101 and an inner housing 102. The inner housing 102 extends upward to form an arched top surface. Heat insulation or heat-resistant material is filled between the outer housing 101 and the inner housing 102. The outer housing 101, the inner housing 102, and the filled heat insulation or heat-resistant material together form a heat insulation layer 103. The inner center of the integrated burner 1 is set as a combustion chamber 11. The combustion chamber 11 is a cylindrical cavity surrounded by the furnace inner wall 111. The top of the furnace inner wall 111 extends into an arch. The outer sides of the middle and lower parts of the furnace inner wall 111 are covered with a furnace outer wall 113. A sandwich structure 114 is arranged between the furnace outer wall 113 and the furnace inner wall 111. A partition 1141 is arranged in the sandwich structure 114. Raw material liquid steam or raw material liquid is filled in the sandwich structure 114 to cool the furnace outer wall 113 and the furnace inner wall 111, prevent the temperature from being too high, and at the same time prevent the temperature of the catalytic chamber 14 from being too high to cause the catalyst to lose its activity. The upper part of the partition 1141 is filled with raw material liquid. An insulating chamber 115 is formed between the lower part of the sandwich structure 114 and the furnace outer wall 113. The insulating chamber 115 is communicated with the steam chamber 13. The insulating chamber 115 is filled with raw material liquid steam;
[0122] The upper part of the furnace outer wall 113 extends away from the combustion chamber 11 and is connected to the inner housing 102. The upper part of the furnace outer wall 113, the upper part of the furnace inner wall 111, the upper part of the inner housing 102, and the partition 1141 are surrounded and connected to form a raw material liquid chamber 12. The raw material liquid introduced into the raw material liquid chamber 12 cannot fill the entire raw material liquid chamber 12, and there is a space for storing steam in the upper part. The raw material liquid chamber 12 is provided with a first interface 121, a fourth interface 124, a second interface 122, and a third interface 123. The first interface 121 and the fourth interface 124 are arranged in the upper part of the raw material liquid chamber 12. The second interface 122 and the third interface 123 are arranged in the lower part of the raw material liquid chamber 12 and are arranged on the furnace outer wall 113 through the housing 10. There is a height difference between the interfaces arranged in the upper part of the raw material liquid chamber 12 and the interfaces arranged in the lower part of the raw material liquid chamber 12 for connecting a liquid level device to measure the liquid level height and replenish the liquid in time. The remaining interfaces are used for replenishing the liquid, or discharging the waste liquid, or setting a safety valve. In this embodiment, a liquid level device is arranged at the first interface 121 and the second interface 122, a liquid replenishing port is arranged at the third interface 123 for replenishing the liquid, and a safety valve is arranged at the fourth interface 124. The raw material liquid chamber 12 is also provided with a first safety port 126 and a steam outlet 125. The steam outlet 125 is used to export the raw material liquid steam. The first safety port 126 is used to connect a pressure measuring device and a pressure switch to ensure the steam pressure in the raw material liquid chamber 12.
[0123] The outer wall 113 of the furnace and the middle part of the inner shell 102 enclose a gas storage chamber 15 and a catalytic chamber 14. The inner side of the gas storage chamber 15 is adjacent to the raw material liquid chamber 12. The raw material liquid chamber 12 also plays a heat insulation role for the gas storage chamber 15 to prevent the gas from expanding due to heat and causing danger. An air outlet interface 151 penetrates through the shell 10 on the side of the gas storage chamber 15. A second safety port 152 penetrates through the shell 10 on the side of the gas storage chamber 15 and extends upward, which is used to connect a pressure gauge for measuring gas pressure, a pressure switch for ensuring pressure, etc. A plurality of temperature sensors 144 are arranged on the side of the catalytic chamber 14 to penetrate through the shell 10, which are used to detect the temperature during the action of the catalyst to ensure the activity of the catalyst and make the catalyst act to the greatest extent. Thus, the inner wall 111 of the furnace and the outer wall 113 of the furnace jointly form a sandwich structure 114, and a heat insulation chamber 115 is formed between the inner wall 111 of the furnace and the outer wall 113 of the furnace. The heat insulation chamber 115 is communicated with the steam chamber 13.
[0124] In addition, in this embodiment, through holes can be arranged on the wall surface between the heat insulation chamber 115 and the steam chamber 13 to realize the communication between the two; alternatively, a first connecting pipe 131 and a second connecting pipe 132 can be connected between the steam chamber 13 and the sandwich structure 114. The first connecting pipe 131 and the second connecting pipe 132 are raw material liquid steam channels, which are used for the exchange of raw material liquid steam between the steam chamber 13 and the sandwich structure 114. A feeding port 143 penetrates through the steam chamber 13 at the bottom of the catalytic chamber 14, which is used for adding or removing the catalyst.
[0125] Embodiment 7
[0126] As shown in the appendix Figures 7-8 This embodiment proposes another specific implementation scheme on the basis of Embodiment 4.
[0127] The furnace body of the integrated burner 1 is enclosed by a shell 10 into a cylindrical shape. The shell 10 includes an outer shell 101 and an inner shell 102. The inner shell 102 extends upward into an arched top surface. Heat insulation or heat insulating materials are filled between the outer shell 101 and the inner shell 102. The combustion chamber 11 is arranged at the center inside the integrated burner 1 and is enclosed by the inner wall 111 of the furnace into a cylindrical shape. The inner wall 111 of the furnace extends upward into an arched top surface. A combustion outlet pipe 112 penetrates through the shell 10 at the upper part of the combustion chamber 11, and a burner 17 is arranged at the lower part.
[0128] On the side of the furnace inner wall 111 away from the combustion chamber 11, a plurality of furnace tubes 111b are annularly connected. The furnace tubes 111b are special-shaped tubes, or semi-circular, or square, or of other shapes. In this embodiment, they are preferably set as semi-circular. The outside of the furnace inner wall 111 is covered with a furnace outer wall 113. The furnace outer wall 113 extends upward to form an arched top surface. Between the furnace outer wall 113 and the furnace inner wall 111 is a sandwich structure 114. The furnace tubes 111b are arranged in the sandwich structure 114. The sandwich structure 114 is provided with a first partition 1141 and a second partition 1142, dividing the sandwich structure 114 into two non-communicating parts. At the connection between the top of the furnace tube 111b and the furnace inner wall 111, the second partition 1142 is closedly arranged. At the connection between the outside of the bottom of the furnace tube 111b and the furnace outer wall 113, the first partition 1141 is closedly arranged. The internal space of the furnace tube 111b communicates with the lower space of the first partition 1141, which is an insulation chamber 18. The insulation chamber 18 communicates with the steam chamber 13 and is filled with raw material liquid steam for cooling the furnace inner wall 111 to prevent overheating damage. The upper space outside the furnace tube 111b separated from the first partition 1141 and the second partition 1142 serves as the raw material liquid chamber 12, which is filled with raw material liquid and can also cool the furnace outer wall 113 to prevent the catalyst from losing activity due to excessive temperature. Therefore, two layers of space are separated in the sandwich structure 114, filled with raw material liquid steam and raw material liquid respectively, playing a double-layer cooling role.
[0129] The raw material liquid introduced into the raw material liquid chamber 12 cannot fill the entire raw material liquid chamber 12, and there is a space for storing steam in the upper part. The raw material liquid chamber 12 is provided with a first interface 121, a fourth interface 124, a second interface 122, and a third interface 123. The first interface 121 and the fourth interface 124 are arranged at the upper part of the raw material liquid chamber 12, and the second interface 122 and the third interface 123 are arranged at the lower part of the raw material liquid chamber 12 and pass through the housing 10 and are arranged on the furnace outer wall 113. There is a height difference between the interfaces arranged at the upper part of the raw material liquid chamber 12 and the interfaces arranged at the lower part of the raw material liquid chamber 12 for connecting a liquid level device to measure the liquid level height and replenish the liquid in time. The remaining interfaces are either for replenishing the liquid, or for discharging waste liquid, or for setting a safety valve. In this embodiment, the first interface 121 and the second interface 122 are provided with liquid level devices, the third interface 123 is provided with a liquid replenishing port for replenishing the liquid, and the fourth interface 124 is provided with a safety valve. The raw material liquid chamber 12 is also provided with a first safety port 126 and a steam outlet 125. The steam outlet 125 is used to export the raw material liquid steam, and the first safety port 126 is used to connect a pressure measuring device and a pressure switch to ensure the steam pressure in the raw material liquid chamber 12.
[0130] Thus, in this embodiment, by arranging the furnace tubes 111b in a special way, a two-layer interlayer structure 114 is formed between the furnace outer wall 113 and the furnace inner wall 111. Among them, as a preferred solution of this embodiment, an insulation chamber 115 is formed between the furnace tubes 111b and the furnace inner wall 111, and the insulation chamber 115 is communicated with the steam chamber 13 through the insulation chamber 18.
[0131] It should be noted that the furnace tubes 111b in this embodiment and the furnace tubes 111b in Embodiment 3 play different roles. Specifically, the furnace tubes 111b in Embodiment 3 are part of the structure of the raw material liquid chamber 12, and the substance inside the furnace tubes 111b is the raw material liquid, which is used to hold the raw material liquid and heat the raw material liquid to evaporate. The furnace tubes 111b in this embodiment are part of the interlayer structure 114, not connected to the raw material liquid chamber 12, and the substance inside the furnace tubes 111b is the raw material liquid steam, which is used to provide heat insulation protection for the catalytic chamber 14.
[0132] At the same time, the raw material liquid chamber 12 is formed between the furnace tubes 111b and the furnace outer wall 113. Specifically, the space between the furnace tubes 111b and the furnace outer wall 113 is part of the total chamber space of the raw material liquid chamber 12.
[0133] The furnace outer wall 113 and the inner shell 102 enclose to form a gas storage chamber 15, a catalytic chamber 14, and a steam chamber 13 from top to bottom in sequence. A first filter plate 141 is arranged at the connection between the bottom of the catalytic chamber 14 and the steam chamber 13 to filter the raw material liquid steam. After filtration, the raw material liquid steam enters the catalytic chamber 14. The catalytic chamber 14 is filled with a catalyst, and the raw material liquid steam reacts under the action of the catalyst to generate water gas. A second filter plate 142 is arranged at the connection between the top of the catalytic chamber 14 and the gas storage chamber 15 to filter the generated water gas and then introduce it into the gas storage chamber 15. A pipeline for exchanging raw material liquid steam is connected between the steam chamber 13 and the lower space of the interlayer structure 114.
[0134] An air outlet interface 151 and a second safety port 152 are provided on the top surface of the gas storage chamber 15 passing through the shell 10. The air outlet interface 151 is used to export the generated water gas, and the second safety port 152 is used to connect a pressure gauge for measuring the gas pressure in the gas storage chamber 15, a pressure switch for ensuring the pressure, etc.
[0135] Embodiment 8
[0136] As shown in the Figures 9-10 attachment, another specific implementation solution is proposed based on Embodiment 4 in this embodiment.
[0137] It should be noted that this embodiment is basically the same as Embodiment 7, except that the furnace tubes 111b are connected to the furnace outer wall 113, and a second partition plate 1142 is hermetically arranged at the connection between the top end of the furnace tubes 111b and the furnace outer wall 113, and a first partition plate 1141 is hermetically arranged at the connection between the outer side of the bottom of the furnace tubes 111b and the furnace inner wall 111.
[0138] Similarly, the internal space of the furnace tube 111b communicates with the lower space of the first partition plate 1141 to form a heat insulation chamber 18. The heat insulation chamber 18 communicates with the steam chamber 13 and is filled with raw material liquid steam for cooling the inner wall 111 of the furnace to prevent overheating damage.
[0139] Thus, in this embodiment, by arranging the furnace tube 111b in a special way, a two-layer sandwich structure 114 is formed between the outer furnace wall 113 and the inner furnace wall 111. Among them, as a preferred solution of this embodiment, an insulation chamber 115 is formed between the furnace tube 111b and the outer furnace wall 113, and the insulation chamber 115 communicates with the steam chamber 13 through the heat insulation chamber 18.
[0140] Similarly, the furnace tube 111b in this embodiment and the furnace tube 111b in Embodiment 3 have different functions. Specifically, the furnace tube 111b in Embodiment 3 is part of the structure of the raw material liquid chamber 12, and the substance inside the furnace tube 111b is the raw material liquid, which is used to hold the raw material liquid and heat the raw material liquid to evaporate. The furnace tube 111b in this embodiment is part of the sandwich structure 114 and does not communicate with the raw material liquid chamber 12. The substance inside the furnace tube 111b is the raw material liquid steam, which is used for heat insulation protection of the catalytic chamber 14.
[0141] Meanwhile, a raw material liquid chamber 12 is formed between the furnace tube 111b and the inner furnace wall 111. Specifically, the space between the furnace tube 111b and the inner furnace wall 111 is part of the total chamber space of the raw material liquid chamber 12.
[0142] Embodiment 9
[0143] As shown in the attached Figures 11-12 figure, another specific implementation scheme is proposed based on Embodiment 4 in this embodiment.
[0144] The furnace body of the integrated burner 1 is enclosed in a cylindrical shape by the housing 10. The housing 10 includes an outer housing 101 and an inner housing 102. The inner housing 102 extends upward to form an arched top surface. Heat insulation or thermal insulation materials are filled between the outer housing 101 and the inner housing 102. Inside the integrated burner 1, a furnace inner wall 111 is provided. The furnace inner wall 111 encloses a cylindrical cavity and extends upward to form an arched top surface. An evaporation chamber 16, a combustion chamber 11, and a raw material liquid chamber 12 are sequentially arranged in the cavity of the furnace inner wall 111 from top to bottom. The raw material liquid chamber 12 and the evaporation chamber 16 are connected by a plurality of furnace tubes 111b provided in the middle of the furnace inner wall 111. The plurality of furnace tubes 111b are arranged at intervals in a ring shape on the inner surface of the furnace inner wall 111, with the upper ends connected to the evaporation chamber 16 and the lower ends connected to the raw material liquid chamber 12. The furnace tubes 111b are special-shaped tubes, or semicircular, or square, or of other shapes. In this embodiment, they are preferably set as semicircular. The raw material liquid steam generated in the raw material liquid chamber 12 enters the evaporation chamber 16 through the furnace tubes 111b. Part of the furnace tubes 111b is filled with raw material liquid and part is filled with raw material liquid steam.
[0145] A first interface 121 and a fourth interface 124 are provided at the bottom of the raw material liquid chamber 12. A second interface 122, a third interface 123, a first safety port 126, and a steam outlet 125 are provided at the top of the evaporation chamber 16. A liquid level device is provided between the first interface 121 or the fourth interface 124 and the second interface 122 or the third interface 123. The other one of the first interface 121 or the fourth interface 124 is a sewage discharge outlet for discharging waste liquid. The other one of the second interface 122 or the third interface 123 is a liquid supplement port for adding raw material liquid. The raw material liquid enters the evaporation chamber 16 and enters the raw material liquid chamber 12 through the furnace tubes 111b.
[0146] A combustion outlet pipe 112 is connected to the upper part of the combustion chamber 11. The evaporation chamber 16 is covered on the outside of the upper part of the combustion chamber 11. A burner 17 is provided at the lower part of the combustion chamber 11. The raw material liquid chamber 12 is covered in a ring shape on the outside of the burner 17. The burner 17 is arranged in the space enclosed by the lower part of the furnace inner wall 111.
[0147] A gas storage chamber 15, a catalytic chamber 14, and a steam chamber 13 are sequentially arranged from top to bottom between the inner casing 102 and the furnace outer wall 113. A steam inlet 131 is arranged at the lower part of the steam chamber 13, which is connected to a steam outlet 125 through a pipeline. The raw material liquid steam discharged from the steam outlet 125 is introduced into the steam chamber 13. A first filter plate 141 is arranged at the connection between the bottom of the catalytic chamber 14 and the steam chamber 13 to filter the raw material liquid steam. The filtered raw material liquid steam enters the catalytic chamber 14. The catalytic chamber 14 is filled with a catalyst. The raw material liquid steam reacts under the action of the catalyst to generate water gas. A second filter plate 142 is arranged at the connection between the top of the catalytic chamber 14 and the gas storage chamber 15. The generated water gas is filtered and then introduced into the gas storage chamber 15. An air outlet interface 151 and a second safety port 152 are arranged at the upper part of the gas storage chamber 15. The air outlet interface 151 is connected to a gas collection device 5 to collect the produced water gas. The second safety port 152 is used to connect a pressure switch or a safety valve device of the water gas to ensure the pressure stability of the water gas inside the integrated burner 1.
[0148] The outer side of the furnace inner wall 111 is annularly coated with the furnace outer wall 113. The furnace inner wall 111 and the furnace outer wall 113 together form a sandwich structure 114, and a heat insulation chamber 115 is formed between the furnace inner wall 111 and the furnace outer wall 113. The heat insulation chamber 115 is communicated with the steam chamber 13, so that the heat insulation chamber 115 is filled with raw material liquid steam for further cooling and heat insulation of the furnace inner wall 111 and the furnace outer wall 113.
[0149] In this embodiment, since the raw material liquid chamber 12 is relatively small in volume with respect to the entire furnace body and stores less raw material liquid, the furnace tube 111b is directly arranged inside the furnace inner wall 111, which is equivalent to being directly located in the furnace chamber. The temperature of the furnace chamber is extremely high, the raw material liquid is heated quickly and evaporates quickly. The flow of the raw material liquid and the flow of the raw material liquid steam can contribute to the heat dissipation of the furnace inner wall 111, and the thermal efficiency is high. The furnace inner wall 111 and the furnace outer wall 113 further dissipate heat through the sandwich structure 114 to ensure that the catalytic chamber 14 connected to the furnace outer wall 113 can maintain an appropriate temperature and prevent the catalyst from losing activity due to excessive temperature.
[0150] It should be noted that the furnace tube 111b in this embodiment is the same as the furnace tube 111b in Embodiment 3 and belongs to the second method in the setting method of the furnace tube 111b in Embodiment 3. Similarly, the furnace tube 111b in this embodiment belongs to the situation where the furnace tube 111b is arranged inside the combustion chamber 11.
[0151] Embodiment 10
[0152] As shown in the appendix Figures 3-4As shown in the figure, the furnace body of the integrated burner 1 is enclosed by a housing 10 to form a cylindrical shape. The housing 10 includes an outer housing 101 and an inner housing 102. Heat insulation or heat-resistant materials are filled between the outer housing 101 and the inner housing 102. The outer housing 101, the inner housing 102, and the filled heat insulation or heat-resistant materials together form a heat insulation layer 103. The inner center of the integrated burner 1 is set as a combustion chamber 11. A combustion outlet pipe 112 is provided on the combustion chamber 11. The exhaust gas generated by combustion in the combustion chamber 11 is discharged through the combustion outlet pipe 112. Therefore, the combustion outlet pipe 112 needs to penetrate the heat insulation layer 103 and extend to the outside of the integrated burner 1 to discharge the exhaust gas to downstream equipment.
[0153] However, since the integrated burner 1 and the heat insulation layer 103 are often cylindrical, during the process of the combustion outlet pipe 112 penetrating the heat insulation layer 103, the combustion outlet pipe 112 will penetrate an arc-shaped surface, which not only makes it inconvenient for assembly but also brings certain difficulties to welding and fixing. In addition, due to the high temperature in the combustion outlet pipe 112, if components such as the assembly structure outside the combustion outlet pipe 112 and the heat insulation layer 103 are heated for a long time, the corresponding materials are prone to overheating and aging, resulting in a deterioration of the mechanical properties and assembly effect of its assembly structure. In severe cases, structural damage and assembly failure may even occur, which is not conducive to improving the service life of the combustion device.
[0154] In view of this, in order to solve the problems such as easy aging and damage due to long-term heating at the exhaust gas outlet of the integrated burner in the prior art, the present embodiment further improves the integrated burner 1:
[0155] The raw material liquid chamber 12 is sleeved outside the combustion chamber 11. The heat insulation layer 103 is sleeved outside the raw material liquid chamber 12. A protective sleeve 127 is provided outside the raw material liquid chamber 12, and the protective sleeve 127 is coaxially arranged with the combustion outlet pipe 112. The combustion outlet pipe 112 penetrates the raw material liquid chamber 12, and the protective sleeve 127 is sleeved outside the combustion outlet pipe 112, and the protective sleeve 127 and the combustion outlet pipe 112 penetrate the heat insulation layer 103 together; that is, the diameter of the protective sleeve 127 is larger than the diameter of the combustion outlet pipe 112, and the two form a sleeve-type structure.
[0156] Specifically, one end of the combustion outlet pipe 112 is communicated with the combustion chamber 11. The other end of the combustion outlet pipe 112 sequentially penetrates the raw material liquid chamber 12 and the heat insulation layer 103 and extends to the outside of the integrated burner 1 to be connected with downstream equipment. One end of the protective sleeve 127 is communicated with the raw material liquid chamber 12. The protective sleeve 127 is sleeved outside the combustion outlet pipe 112. The other end of the protective sleeve 127 penetrates the heat insulation layer 103 and extends to the outside of the integrated burner 1.
[0157] At least liquid raw material liquid and / or raw material liquid vapor is filled between the protective sleeve 127 and the combustion outlet pipe 112.
[0158] Preferably, the protective sleeve 127 and the combustion outlet pipe 112 are concentrically arranged.
[0159] Thus, by setting the cooperation between the protective sleeve 127 and the combustion outlet pipe 112, it is avoided that the combustion outlet pipe 112 with a higher temperature directly penetrates the heat insulation layer 103, resulting in the situation that the corresponding assembly structure and the heat insulation layer 103 are locally heated, aged and damaged for a long time. At the same time, during the operation of the integrated burner 1, the space between the protective sleeve 127 and the combustion outlet pipe 112 is filled with liquid raw material liquid and / or raw material liquid vapor, which can further absorb the heat in the combustion outlet pipe 112 to reduce the temperature in the combustion outlet pipe 112, thereby being beneficial to enhancing the protection performance of the protective sleeve 127 against local high temperature.
[0160] A sealing plate 128 is arranged at the end of the protective sleeve 127 far from the raw material liquid chamber 12, and the combustion outlet pipe 112 cooperates with the sealing plate 128 and penetrates through the sealing plate 128.
[0161] Preferably, the sealing plate 128 has a flat plate structure. Compared with the arc-shaped outer wall of the conventional combustion outlet pipe 112 penetrating the heat insulation layer 103, when the combustion outlet pipe 112 extends outwards, it only directly contacts and assembles with the sealing plate 128, which not only simplifies the assembly structure, but also in the process of welding and fixing, the welding area is on a plane rather than an arc surface in the prior art, thus being beneficial to reducing the welding difficulty and improving the production efficiency.
[0162] Embodiment 11
[0163] Since there is such a production process in the production system: combustion releases heat, the raw material liquid is heated and evaporated to form raw material vapor, and the raw material vapor catalyzes the production of water gas.
[0164] Therefore, in order to maintain such a production process in the system, the system further includes a steam supply device;
[0165] For the steam supply device, it can be a conventional boiler; similarly, another embodiment of the steam supply device is proposed in this embodiment. The steam supply device is basically the same as the integrated burner 1 in any one of Embodiments 1-10. The difference is that the steam pipeline outlet of the steam supply device is connected to the steam inlet 131 of the integrated burner 1, so that the raw material vapor generated in the steam supply device enters the integrated burner 1 to participate in the catalytic reaction, providing stable raw material vapor support for the operation of the integrated burner 1.
[0166] Embodiment 12
[0167] Based on any one of Embodiments 1-11, this embodiment proposes a production process, including:
[0168] S1. The system is started and ignited for combustion;

[0173] S2. Heat is released by combustion, and the raw material liquid in the raw material liquid chamber 12 is heated and evaporated into raw material vapor;
[0174] S3. The raw material vapor enters the water gas preparation chamber from the raw material liquid chamber 12, undergoes a catalytic reaction, and generates water gas, thereby realizing the production of water gas;
[0175] Specifically:
[0176] S301. The raw material vapor enters the steam chamber 13 through the steam pipeline 9;
[0177] S302. A part of the raw material vapor in the steam chamber 13 enters the catalytic chamber 14 and undergoes a catalytic reaction to generate water gas; another part of the raw material vapor in the steam chamber 13 enters the sandwich structure 114 to provide heat insulation for the catalytic chamber 14;
[0178] S303. The water gas generated in step S302 enters the gas storage chamber 15 and enters the gas collection device 5 through the gas outlet interface 151.
[0179] It should be noted that in order to avoid ambiguity, the description in this embodiment is based on the relevant components of the integrated burner 1, rather than the component structures of the steam supply device, gas supply device, etc. in Embodiment 11.
[0180] Embodiment 13
[0181] Since Embodiment 12 is an introduction to the production process, it can be regarded as an ideal system operation condition; however, in the actual production process, factors such as heat loss and material fluctuations often exist, making it difficult for the system to maintain stable output; therefore, based on any one of Embodiments 1-11, this embodiment proposes a water gas production system.
[0182] The production system includes a central processor for correspondingly controlling the operation of the system; a memory is set in the central processor for storing data related to the system operation;

[0189] In addition, the system further includes an alarm. The central processor is connected to the alarm and is used to alarm corresponding fault situations during the operation of the system.
[0190] It should be noted that, in order to avoid ambiguity, the description in this embodiment is based on the relevant components of the integrated burner 1, rather than the component structures of the steam supply device, gas supply device, etc. in Embodiment 11.
[0191] Meanwhile, this embodiment proposes a control method for a water gas production system, which at least includes: a control method during the system startup process;
[0192] The control method during the system startup process includes the following steps:
[0193] B1. The central processor controls the fuel control valve to open and controls the ignition device to ignite.
[0194] B2. The central processing unit obtains the liquid level in the raw material liquid chamber 12 through the liquid level device, and determines whether the liquid level in the raw material liquid chamber 12 reaches the preset liquid level value; if yes, go to step B4; if no, go to step B3;
[0195] B3. The central processing unit controls the replenishing pump 3 to start, replenishes the raw material liquid into the raw material liquid chamber 12, and returns to step B2;
[0196] B4. The central processing unit obtains the temperature in the catalytic chamber 14 in real time through the temperature detection device 144;
[0197] B5. The central processing unit determines whether the temperature in the catalytic chamber 14 meets the requirements of the preset temperature range; if yes, go to step B6; if no, return to step B4;
[0198] B6. The central processing unit obtains the raw material steam flow rate in real time through the steam flowmeter;
[0199] B7. The central processing unit determines whether the raw material steam flow rate reaches the preset steam flow rate value; if yes, go to step B8; if no, return to step B6;
[0200] B8. The central processing unit obtains the water gas flow rate in real time through the water gas flowmeter;
[0201] B9. The central processing unit determines whether the water gas flow rate reaches the preset flow rate value; if yes, go to step B10; if no, return to step B8;
[0202] B10. The central processing unit maintains the current system operating state.
[0203] That is, step B10 is the process of maintaining the system operation after completing the system startup process.
[0204] In step B5, the preset temperature range includes the maximum preset temperature and the minimum preset temperature;
[0205] Step B5 includes:
[0206] B51. The central processing unit determines whether the temperature in the catalytic chamber 14 is greater than the maximum preset temperature; if yes, go to step B52; if no, go to step B53;
[0207] Among them, if the temperature in the catalytic chamber 14 is greater than the maximum preset temperature, it means that the temperature in the catalytic chamber 14 is relatively high, and the temperature situation in the catalytic chamber 14 needs to be further processed;
[0208] B52. The central processing unit determines whether the change amount or change rate of the temperature in the catalytic chamber 14 within a unit time exceeds the preset value; if yes, the central processing unit reduces the opening degree of the fuel control valve, and then goes to step B6; if no, directly go to step B6;
[0209] Among them, if the change amount or change rate of the temperature in the catalytic chamber 14 within a unit time exceeds a preset value, it indicates that the temperature rise in the catalytic chamber 14 is relatively large. It is necessary to adjust the opening degree of the fuel control valve to reduce the fuel supply amount, so as to avoid the situation that the catalyst is deactivated at high temperature due to the too high temperature in the catalytic chamber 14.
[0210] B53. The central processing unit determines whether the temperature in the catalytic chamber 14 is less than the minimum preset temperature; if yes, go to step B54; if no, go to step B6.

It is necessary to further process the temperature situation in the catalytic chamber 14;

Based on Embodiment 13, this embodiment further introduces the control method.
[0218] This embodiment is basically the same as Embodiment 13. The difference is that the control method of the water gas production system further includes at least: the control method during the operation process after the system starts; or the control steps subsequent to Step B10 in Embodiment 13.
[0219] The control method during the operation process after the system starts includes the following steps:
[0220] B11. The central processor obtains the liquid level in the raw material liquid chamber 12 through the liquid level device again, and judges whether the liquid level in the raw material liquid chamber 12 reaches the preset liquid level value; if yes, go to Step B13; if no, go to Step B12;
