Description

Technical Field

[0001] The utility model relates to the technical field of ammonium sulfate production, and in particular to an energy-saving and efficiency-enhancing structure and process for ammonium sulfate. Background Art

[0002] Ammonium sulfate is a colorless crystal or white granular inorganic substance. Ammonium sulfate is mainly used as a fertilizer and is suitable for various soils and crops. It can make branches and leaves grow vigorously and improve fruit quality and yield. In addition, it can also be used in textiles, leather, medicine and other aspects. Ammonium sulfate has a variety of applications. For example, ammonium sulfate is usually used as a fertilizer or fertilizer additive in agriculture. In industry, ammonium sulfate is usually added to electroplating solution to increase the conductivity of the electroplating solution, as a raw material for rare earth mining, etc. In this regard, ammonium sulfate, as a commonly used inorganic substance, is also increasing in demand year by year in the market. Among them, in order to improve the conversion rate of ammonium sulfate, the production process of ammonium sulfate is also constantly updated.

[0003] For example, the patent document with publication number CN104649298A discloses a method for producing ammonium sulfate, and the operation steps include: A. coke oven gas and ammonia react with sulfuric acid solution in the saturator spray zone to obtain product a; B. ammonia water is introduced into the overflow tank to react with sulfuric acid solution to obtain product b, and product b is transported to the saturator through a small mother liquor circulation pump, and reacts with the sprayed sulfuric acid solution in the saturator spray zone to obtain product c; C. product a and product c enter the crystallization zone of the saturator, and ammonium sulfate in product a and product c gradually crystallizes and precipitates; D. crystallization liquid containing ammonium sulfate is transported from the crystallization liquid outlet to the crystallization high-level tank through a crystallization pump; E. The crystallization liquid in the crystallization high-level tank is transported to a centrifuge for separation, and the separated precipitate is transported to a dryer for drying to obtain ammonium sulfate.

[0004] Although the above technical scheme can ensure the full utilization of ammonia gas in the production process of ammonium sulfate and avoid the problem of excess ammonia water; however, in the production process of ammonium sulfate, ammonia water and sulfuric acid solution need to react at high temperature. In order to ensure the efficiency of the reaction between sulfuric acid and ammonia water and the quality of the produced ammonium sulfate, it is usually necessary to ensure the stability of the temperature during the reaction. In the prior art, in the production process of ammonium sulfate, it is usually necessary to use external heating to ensure the stability of the temperature during the reaction, which leads to an increase in energy consumption in the production process of ammonium sulfate, which is not conducive to the control of the production cost of ammonium sulfate. Utility Model Content

[0005] The utility model aims to provide an energy-saving and efficiency-enhancing structure and process for ammonium sulfate, so as to solve the technical problem that the energy consumption in the production process of ammonium sulfate in the prior art increases, which is not conducive to the control of the production cost of ammonium sulfate.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ammonium sulfate energy-saving and efficiency-enhancing structure, comprising a reactor and a condenser, wherein a reaction chamber is provided in the reactor, the reaction chamber is connected to the condenser, the reaction chamber is used to react raw materials to generate ammonium sulfate gas, and the condenser is used to condense the ammonium sulfate gas generated in the reaction chamber; a temperature adjustment chamber is also provided in the reactor, the temperature adjustment chamber is spaced apart from the reaction chamber, a temperature adjustment chamber input port and a temperature adjustment chamber output port are provided on the temperature adjustment chamber, the temperature adjustment chamber input port is connected to the condenser, the temperature adjustment chamber is used to adjust the temperature of the reaction chamber by cooling water in the condenser, and the temperature adjustment chamber output port is used to output the cooling water in the temperature adjustment chamber.

[0007] The principle and advantage of this scheme are: when reacting ammonium sulfate, the raw materials are transported to the reactor in proportion and reacted at high temperature to generate ammonium sulfate gas, and the ammonium sulfate gas generated by the reactor is condensed and converted into ammonium sulfate solution through a condenser. After the ammonium sulfate gas is transported to the condenser, cooling water is transported into the condenser to absorb the heat in the ammonium sulfate gas, so that the ammonium sulfate gas condenses to form an ammonium sulfate solution, and the cooling water that absorbs the heat of the ammonium sulfate gas is transported to the temperature control chamber of the reactor, and the cooling water is heated in the temperature control chamber during the reaction of the reaction chamber, and the reaction chamber is kept warm by the high specific heat capacity principle of the cooling water; when the reaction chamber needs to be cooled, cooling water is input into the temperature control chamber to reduce the water temperature in the temperature control chamber, and the heat in the reaction chamber is absorbed to achieve the cooling operation of the reaction chamber.

[0008] When reacting ammonium sulfate, this solution sets a temperature-adjusting chamber in the reactor and delivers the cooling water condensed in the condenser to the temperature-adjusting chamber to adjust the temperature of the reaction chamber, so that the cooling water absorbs the heat in the gas during the condensation process to keep the reaction chamber warm, thereby improving the energy utilization rate during the reaction process, reducing the energy consumption required to maintain the reaction temperature during the reaction process, and avoiding the temperature of the cooling water delivered to the temperature-adjusting chamber being too low, resulting in excessive temperature fluctuations in the reaction chamber, affecting the normal progress of the reaction. In addition, by injecting cooling water into the temperature-adjusting chamber, the heat emitted from the reaction chamber during the insulation process is collected, and the heated cooling water is recycled, thereby improving the energy utilization rate during the reaction process.

[0009] Preferably, as an improvement, the temperature adjustment chamber is located in the side wall of the reactor, and the temperature adjustment chamber surrounds the circumference of the reaction chamber, so that the temperature adjustment chamber can evenly adjust the temperature of the reaction chamber in the circumference of the temperature adjustment chamber, thereby improving the temperature adjustment effect of the temperature adjustment chamber on the reaction chamber.

[0010] Preferably, as an improvement, a partition is provided in the temperature regulating chamber, two ends of the partition extend toward two ends of the temperature regulating chamber along the height direction, and the partition is used to separate two sides of the temperature regulating chamber along the extending direction of the partition from each other.

[0011] Preferably, as an improvement, the partition is sealed to the inner wall of the temperature regulating chamber, so that the water in the temperature regulating chamber can flow in one direction under the action of the partition, thereby increasing the coverage of the cooling water flow area in the temperature regulating chamber.

[0012] Preferably, as an improvement, the temperature control chamber input port and the temperature control chamber output port are located on both sides of the partition, so that the cooling water delivered by the temperature control chamber input port can move around the reaction chamber in the temperature control chamber and then be output through the temperature control chamber output port, so as to avoid the temperature control chamber input port and the temperature control chamber output port being too close, which causes the cooling water to be quickly output from the temperature control chamber output port after being input into the temperature control chamber, so that the water filled in the area of ​​the temperature control chamber far from the temperature control chamber input port and the temperature control chamber output port cannot be updated by the newly input cooling water, which causes the temperature difference between the various areas of the temperature control chamber to be easy to occur, and affects the regulating effect of the temperature control chamber on the reaction chamber temperature.

[0013] Preferably, as an improvement, the temperature control chamber input port and the temperature control chamber output port are both located on the side wall of the reactor near the top of the reactor, and the position of the temperature control chamber output port on the reactor is not higher than the position of the temperature control chamber input port. After the cooling water is transported to the temperature control chamber, the cooling water moves to the bottom of the temperature control chamber and squeezes the high-temperature water to move upward, so that the water temperature in the heat exchange chamber can be quickly adjusted; and the temperature control chamber output port is set at the top of the temperature control chamber, so that the temperature control chamber output port can preferentially discharge the water with higher temperature at the top, thereby improving the temperature regulation efficiency of the temperature control chamber, and the temperature control chamber output port can be used as an overflow port of the temperature control chamber, so that the excess water in the temperature control chamber can be discharged in time.

[0014] Preferably, as an improvement, a control valve is provided on the pipeline between the temperature regulating chamber input port and the condenser, so that the delivery of cooling water can be adjusted according to actual needs during the reaction process, ensuring that the temperature of the cooling water in the temperature regulating chamber matches the actual needs of the reaction chamber, improving the regulating effect of the temperature regulating chamber on the temperature in the reaction chamber, and ensuring the normal progress of the reaction process.

[0020] A reaction chamber 101 is provided in the reactor 1, and a feed port 102 and a discharge port 103 are provided on the reactor 1, and both the feed port 102 and the discharge port 103 penetrate the outer wall of the reactor 1 and communicate with the reaction chamber 101.

[0021] The condenser 2 includes a condensation chamber and a cooling water chamber, and an input port and an output port are provided at both ends of the condensation chamber. The specific input port and the output port are located at corresponding positions of the side wall of the condenser 2 and the two ends of the condensation chamber and are connected to the condensation chamber. The input port of the condensation chamber is connected to the discharge port 103 of the reactor 1 through a pipeline, and the output port of the condensation chamber is connected to the output pipe, which is used to transport the ammonium sulfate solution formed after condensation in the condensation chamber to the next processing step for processing; the condenser 2 is also provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively located at At both ends of the cooling water chamber, the water inlet and the water outlet respectively penetrate the side wall of the condenser 2 and are connected to the condensing chamber; the end of the water inlet away from the cooling water chamber is connected to the circulating water pipe through the water inlet pipe 201, and the water inlet is used to transport cooling water into the cooling water chamber, and the cooling water is used to heat exchange and cool the gas in the condensing chamber in the condenser 2; the end of the water outlet away from the cooling water chamber is connected to the water outlet pipe 202, and the end of the water outlet pipe 202 away from the water outlet is connected to the circulating water pool, and the water outlet pipe 202 is used to output the cooling water after heat exchange in the cooling water chamber. The specific structure and distribution position of the condensing chamber and the cooling water chamber are prior art, and will not be repeated here.

[0022] As attached Figure 2As shown, a temperature regulating chamber 104 is also provided on the reactor 1. Specifically, the temperature regulating chamber 104 is located in the side wall of the reactor 1 and is spaced apart from the reaction chamber 101. The temperature regulating chamber 104 surrounds the circumference of the reaction chamber 101. Specifically, the reaction chamber 101 is sleeved in the temperature regulating chamber 104. The temperature regulating chamber input port 105 and the temperature regulating chamber output port 106 penetrate the side wall of the reactor 1, wherein the temperature regulating chamber input port 105 is connected to the water outlet pipe 202 through a pipeline, and the temperature regulating chamber input port 105 is used to transport the cooling water in the water outlet pipe 202 into the temperature regulating chamber 104. The temperature regulating chamber output port 106 is connected to a pipeline, and the temperature regulating chamber output port 106 is used to output the water in the temperature regulating chamber 104, wherein the water output from the temperature regulating chamber 104 is heated to form high-temperature water during the reaction process of the reaction chamber 101, and can be used for industrial heating water after being output through the temperature regulating chamber output port 106. This allows water resources to be reused during the reaction process, reducing water resource consumption during the reaction process and reducing costs during the production process. At the same time, the heat energy generated during condensation and reaction can be absorbed through cooling water, and the absorbed heated water can be recycled to improve the recycling rate of heat energy.

[0023] A partition 107 is engaged and connected in the temperature control chamber 104, and both ends of the partition 107 extend toward both ends of the temperature control chamber 104 along the height direction. The partition 107 is used to separate the two sides of the temperature control chamber 104 along the extension direction of the partition 107 from each other, and each side of the partition 107 is sealed and connected to the inner wall of the temperature control chamber 104 through a sealing ring. The temperature control chamber input port 105 and the temperature control chamber output port 106 are respectively located on both sides of the partition 107. The cooling water delivered by the temperature control chamber input port 105 can move around the reaction chamber 101 in the temperature control chamber 104 and then be output through the temperature control chamber output port 106, thereby preventing the temperature control chamber input port 105 and the temperature control chamber output port 106 from being too close to each other, causing the cooling water to be quickly output from the temperature control chamber output port 106 after being input into the temperature control chamber 104, so that the water filled in the area of ​​the temperature control chamber 104 far away from the temperature control chamber input port 105 and the temperature control chamber output port 106 cannot be updated by the newly input cooling water, resulting in temperature differences in various areas of the temperature control chamber 104, thereby affecting the temperature regulation effect of the temperature control chamber 104 on the reaction chamber 101.

[0024] The temperature control chamber input port 105 and the temperature control chamber output port 106 are both located on the side wall of the reactor 1 near the top of the reactor 1 and at a position corresponding to the temperature control chamber 104, wherein the position of the temperature control chamber output port 106 on the tower body is not higher than the position of the temperature control chamber input port 105. Preferably, in this embodiment, the temperature control chamber input port 105 and the temperature control chamber output port 106 are at the same height position on the reactor 1. After the cooling water is transported to the temperature control chamber 104, the low-temperature cooling water is lower than the high-temperature water in the temperature control chamber 104, the cooling water moves to the bottom of the temperature control chamber 104 and squeezes the high-temperature water to move upward, and heat exchange is performed during the mutual movement of the cooling water and the high-temperature water, so that the water temperature in the heat exchange chamber can be quickly adjusted, and the cooling water is prevented from being input from the bottom of the temperature control chamber 104, resulting in the cooling water and the high-temperature water being separated due to the density difference, which affects the effect of water temperature regulation in the temperature control chamber 104. In addition, the temperature regulating chamber output port 106 is arranged at the top of the temperature regulating chamber 104, so that when the temperature regulating chamber output port 106 outputs the water in the temperature regulating chamber 104, the water with higher temperature at the top of the temperature regulating chamber 104 can be output preferentially, so that when the cooling water is input into the temperature regulating chamber 104 to cool the high-temperature water, the excess high-temperature water is output through the temperature regulating chamber output port 106, so as to ensure that the excess high-temperature water in the temperature regulating chamber 104 can be discharged in time, thereby improving the temperature regulation efficiency of the temperature regulating chamber 104, and the temperature regulating chamber output port 106 is opened at the top of the temperature regulating chamber 104, so that the temperature regulating chamber output port 106 can be used as an overflow port of the temperature regulating chamber 104, so that when there is too much water in the temperature regulating chamber 104, it can be automatically discharged through the temperature regulating chamber output port 106, thereby avoiding excessive water pressure caused by excessive water in the temperature regulating chamber 104, resulting in damage to the structure of the temperature regulating reactor 1.

[0025] A control valve 3 is also installed on the pipe connecting the water outlet pipe 202 and the temperature adjustment chamber input port 105, and the control valve 3 is used to control the opening and closing of the temperature adjustment chamber input port 105. In this way, the delivery of cooling water can be adjusted according to actual needs during the reaction process, ensuring that the temperature of the cooling water in the temperature adjustment chamber 104 matches the actual needs of the reaction chamber 101, improving the adjustment effect of the temperature adjustment chamber 104 on the temperature in the reaction chamber 101, and ensuring the normal progress of the reaction process.

[0026] The specific implementation process is as follows:

[0027] When reacting ammonium sulfate, the raw materials are transported to the reactor 1 in proportion and reacted at high temperature to generate ammonium sulfate gas. The ammonium sulfate gas generated by the reactor 1 is condensed and converted into an ammonium sulfate solution through the condenser 2. After the ammonium sulfate gas is transported to the condenser 2, cooling water is transported into the condenser 2 to absorb the heat in the ammonium sulfate gas, so that the ammonium sulfate gas is condensed to form an ammonium sulfate solution. The cooling water that absorbs the heat of the ammonium sulfate gas is transported to the temperature adjustment chamber 104 of the reactor 1. The cooling water is heated in the temperature adjustment chamber 104 during the reaction of the reaction chamber 101, and the reaction chamber 101 is kept warm by the high specific heat capacity principle of the cooling water; when the reaction chamber 101 needs to be cooled, the cooling water is input into the temperature adjustment chamber 104 to reduce the water temperature in the temperature adjustment chamber 104, and the heat in the reaction chamber 101 is absorbed to achieve the cooling operation of the reaction chamber 101.

[0028] Compared with the prior art, when reacting ammonium sulfate, the present solution sets a temperature regulating chamber 104 in the reactor 1, and transports the cooling water condensed in the condenser 2 to the temperature regulating chamber 104 to regulate the temperature of the reaction chamber 101, so that the cooling water absorbs the heat in the gas during the condensation process to keep the reaction chamber 101 warm, thereby improving the utilization rate of energy during the reaction process, reducing the energy consumption required for the reaction chamber 101 to maintain the reaction temperature during the reaction process, and avoiding the temperature of the cooling water transported to the temperature regulating chamber 104 being too low, resulting in excessive temperature fluctuations in the reaction chamber 101, and affecting the normal progress of the reaction. In addition, by injecting cooling water into the temperature regulating chamber 104, the heat emitted from the reaction chamber 101 during the insulation process is collected, and the heated cooling water is recycled, thereby improving the utilization rate of energy during the reaction process.

[0029] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
