Description

Technical Field

[0001] This invention relates to the field of steam application technology, and more specifically to a steam flow regulation system. Background Technology

[0002] Steam heating is a common heating method in factories. During the heating process, the steam exchanged in the heat exchanger is in a gaseous state. Steam heat exchange primarily utilizes the latent heat of the steam. The steam does not directly contact the object being heated. When the steam condenses (changes phase to liquid), it releases a large amount of heat. However, in existing technologies, saturated steam may experience pressure or temperature drops during transportation due to pipeline length limitations, leading to reduced heating efficiency. Furthermore, the residual steam after heating needs to condense back to a liquid state and be reheated, resulting in some of the steam's heat not being fully utilized. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] This embodiment of a steam flow regulation system includes a heating unit 4, configured to heat an object to be heated, which includes, but is not limited to, food, medicine, and chemicals. It also includes a return tank 51, in which steam accumulates after heating. The return tank 51 is configured to separate the steam and liquid discharged from the heating unit 4.

[0033] Heating tank 3 is configured to heat the liquid in return tank 51 and supply steam to heating unit 4; and

[0034] The regulating unit 1 includes several regulating components 100. These components 100 are configured to collect steam from the return tank 51 and replenish steam to the heating tank 3. It should be noted that the steam temperature stored in each regulating component 100 is different, primarily achieved through pressure control within each component 100 and heating power control of the heating unit 2.

[0035] The heating section 2 includes a second heating zone 209 and a plurality of first heating zones 203. The plurality of first heating zones 203 are configured to correspond one-to-one with a plurality of regulating components 100, and the temperatures of the plurality of first heating zones 203 are all different. The plurality of first heating zones 203 are configured to provide the required heating temperature to the corresponding regulating components 100 respectively. The second heating zone 209 is configured to provide the required heating temperature to the heating tank section 3.

[0036] This invention establishes a steam heating pipeline system. The flow meters, temperature sensors, differential pressure sensors 313, and pressure sensors on each pipe are compared based on actual heating requirements to control and adjust the temperature and quantity of steam in the heating unit 4 in real time. Furthermore, this invention includes an adjustment unit 1 and a return tank 51 to separate the used steam and liquid. The used steam, still at a high temperature, is sequentially placed into storage tanks 107 in different adjustment components 100 to obtain steam at different temperatures and pressures (typically saturated steam and / or superheated steam). Based on the actual temperature, pressure, and flow rate of the steam in the main intake pipe 301, the first air pump 111 in the corresponding storage tank 107 is activated to deliver the required steam into the main intake pipe 301, ensuring the steam in the main intake pipe 301 meets the desired steam requirements. Simultaneously, combined with the control system, the start / stop and power adjustments of various components in the pipeline system can be automatically adjusted according to various conditions, saving manpower and resources.

[0037] In one embodiment, the power setting of the first heating zone 203 increases sequentially, that is, the preset pressure setting of the corresponding regulating component 100 (the preset pressure of the first pressure solenoid valve 105) also increases sequentially. The advantage of this setting is that the temperature of the heating liquid passing through the first heating zone 203 is gradually heated, ensuring that the temperature of each regulating component 100 also gradually increases. After passing through the last first heating zone 203, the temperature of the liquid used for heating has been heated to a higher temperature. After passing through the second heating zone 209, the temperature of the heating liquid can be quickly raised to the required temperature for heating and vaporizing the liquid in the main tank 305.

[0038] In one embodiment, the heating unit 4 includes a hot zone 42, a cold zone 45, a heating space 43, a heat exchange tube 44, and a conveying pipe 41. The object to be heated enters the heat exchange tube 44 through the conveying pipe 41. The heat exchange tube 44 is built into the heating space 43. The heating space 43 is connected to the main air inlet pipe 301 and the secondary return pipe 54. The heating space 43 is filled with a large amount of steam (usually supersaturated steam). The steam releases latent heat to heat the heating tube. After the object to be heated is heated by the heating tube, it enters the hot zone 42 and is discharged through the conveying pipe 41.

[0039] Specifically, the heat exchange tube 44 can be bent several times in the heating space 43 to allow the object to be heated sufficient heating time.

[0040] Specifically, the heating unit 4 includes a housing, and a hot zone 42, a cold zone 45 and a heating space 43 are provided inside the housing. The three zones are not directly connected, but the hot zone 42 and the cold zone 45 are connected through a heating pipe.

[0041] In one embodiment, the regulating component 100 includes a first safety valve 103, a first pressure sensor 104, a fourth temperature sensor 102, a plurality of gas storage tanks 107, and a plurality of connecting pipes. The plurality of gas storage tanks 107 are connected in sequence through connecting pipes. Each connecting pipe is provided with a first pressure solenoid valve 105. The first safety valve 103, the fourth temperature sensor 102, and the first pressure sensor 104 are disposed on the gas storage tanks 107.

[0042] Specifically, the electrical signals of the first safety valve 103 and the first pressure sensor 104 are set so that when the first pressure sensor 104 detects that the pressure has reached the upper limit, the first safety valve 103 is automatically opened to release the gas. This not only ensures the safety of the gas storage tank 107, but also prevents the gas storage tank 107 from overheating due to excessive pressure.

[0043] Specifically, the first pressure solenoid valve 105 can be preset with a pressure. When the internal pressure of the front gas tank 107 is detected to reach the preset pressure value, the first pressure solenoid valve 105 opens to ensure that the pressure and temperature of the gas tank 107 filled with gas can remain consistent. When the internal pressure of the gas tank 107 drops below the preset pressure value, the first pressure solenoid valve 105 closes.

[0044] Furthermore, the first pressure solenoid valve 105 can be configured as a combination of a pressure sensor and a regular solenoid valve, that is, when the pressure sensor detects that the air pressure exceeds the preset pressure, the regular solenoid valve opens.

[0045] Specifically, when the first air pump 111 is started, the first pressure solenoid valve 105 can be opened to replenish air into the front air tank 107.

[0046] In one embodiment, the first pressure solenoid valve 105 can be replaced with an air pump and a pressure sensor. The air pump is controlled to start and rotate in both directions by detecting the air pressure in the air tank 107 and the opening and closing of the first air pump 111 through the pressure sensor.

[0047] In one embodiment, as shown in the attached figure, the first safety valve 103 and the first pressure sensor 104 are disposed on the last gas storage tank 107. The advantage of this arrangement is that it can ensure the maximum gas storage capacity in the gas storage tank 107.

[0048] In one embodiment, as shown in the accompanying drawings, a fourth temperature sensor 102 is at least disposed on an air storage tank 107 connected to a first air intake pipe 106.

[0049] Specifically, the fourth temperature sensor 102 is connected to the gas storage tank 107 in the regulating assembly 100.

[0050] In one embodiment, the regulating assembly 100 further includes a regulating pipe 109, a first flow meter 110, a first air pump 111, and a second pressure valve 108. One end of the regulating pipe 109 is connected to one of the gas storage tanks 107, and the other end of the regulating pipe 109 is connected to the heating tank section 3. The first flow meter 110, the first air pump 111, and the second pressure valve 108 are all mounted on the regulating pipe 109. The first air pump 111 can send the steam in the gas storage tank 107 into the main air inlet pipe 301 for pressurization and heating. The purpose of the first flow meter 110 is to calculate the actual replenishment volume. When the preset replenishment volume is reached, the first air pump 111 is controlled to shut down.

[0051] Specifically, the second pressure valve 108 is located near the connection between the gas storage tank 107 and the regulating pipe 109. The advantage of this arrangement is that it reduces the gas pressure inside the regulating pipe 109.

[0052] Specifically, the first air pump 111 is located at the connection between the regulating pipe 109 and the main air intake pipe 301. The advantage of this arrangement is that it further reduces the air pressure in the regulating pipe 109.

[0053] In one embodiment, the regulating assembly 100 further includes a first air inlet pipe 106 and at least one third air pump 112. One end of the first air inlet pipe 106 is connected in series with one of the air storage tanks 107 of the plurality of regulating assemblies 100, and the other end of the first air inlet pipe 106 is connected to the return tank 51. The third air pump 112 is disposed in the first air inlet pipe 106 section between adjacent regulating assemblies 100.

[0054] Specifically, the first air inlet pipe 106 is provided with several sections, which respectively connect the air storage tanks 107 in the adjacent adjustment components 100, and one of the first air inlet pipes 106 is used to connect the return tank 51 and the air storage tank 107.

[0055] Specifically, a third air pump 112 is installed between adjacent air storage tanks 107, and a third air pump 112 is also installed between air storage tanks 107 connected to the return tank 51.

[0056] In one embodiment, the regulating component 100 is provided with at least two sets, wherein the steam in at least one set of the gas storage tank 107 is below the preset temperature, and the steam in at least one set of the gas storage tank 107 is above the preset temperature.

[0057] In one embodiment, the regulating component 100 is provided with three sets, one set of which has steam in the gas storage tank 107 below the preset temperature, another set of which has steam in the gas storage tank 107 above the preset temperature, and the remaining set of which has steam in the gas storage tank 107 at the same preset temperature.

[0058] In one embodiment, the connection between the regulating pipe 109 and the main intake pipe 301 is located at one end of the main intake pipe 301 near the heating section 4. The advantage of this arrangement is that the steam after temperature and flow adjustment can be used for heating immediately.

[0059] In one embodiment, the heating unit 2 further includes a heat exchanger 201, and a plurality of first heating zones 203 provide the required heating temperature to the corresponding regulating component 100 through the heat exchanger 201. The first heating zone 203 includes a first heating tube 202, a first heater 204, and a first liquid pump 207. The plurality of first heating zones 203 are connected in series with the heat exchanger 201 through the first heating tube 202. The first liquid pump 207 and the first heater 204 are both disposed on the first heating tube 202.

[0060] In one embodiment, the heating section 2 further includes a second heater 210, a second liquid pump 208, and a second heating tube 211. The two ends of the second heating tube 211 are respectively connected to the two ends of the heat exchanger 201 so that the first heating tube 202, the second heating tube 211, and the heat exchanger 201 form a circuit. The second liquid pump 208 is disposed on the second heating tube 211, and the second heater 210 is disposed on the part of the second heating tube 211 connected to the liquid outlet end of the heat exchanger 201. The second heating tube 211 extends into the heating tank section 3.

[0061] In one embodiment, the liquid heated inside the heating section 2 includes, but is not limited to, oil.

[0062] The heating section 2 as a whole forms a loop. The flow process of the first heating zone 203 is as follows: the heat exchanger 201, the first liquid pump 207, and the first heater 204 flow back into the heat exchanger 201, and then connect with the next set of first liquid pumps 207 and first heaters 204. After alternating in sequence, they are connected to the second heating zone 209.

[0063] In one embodiment, a heat insulation plate is provided between the areas where each of the first heaters 204 is connected to the heat exchanger 201, so that the heat exchanger 201 has several temperature zones inside.

[0064] Specifically, the heat exchanger 201 can either enclose the corresponding gas storage tank 107 for heating, or a portion of the heat exchanger 201 can be placed inside the gas storage tank 107 for heating.

[0065] Specifically, the second heating tube 211 extends into the main tank 305 and is wound inside the heating tube to increase the contact area with the main tank 305.

[0066] In one embodiment, the heating tank section 3 includes a main tank 305, a first temperature sensor 310, a second pressure sensor 303, a main air inlet pipe 301, a main return pipe 307, a second temperature sensor 311, a second air pump 312, a differential pressure sensor 313, a second flow meter 314, and a third temperature sensor 315. The first temperature sensor 310 and the second pressure sensor 303 are disposed on the main tank 305. The main air inlet pipe 301 connects the main tank 305 and the heating section 4. The second temperature sensor 311, the second air pump 312, the differential pressure sensor 313, the second flow meter 314, and the third temperature sensor 315 are arranged sequentially along the air delivery direction of the main air inlet pipe 301. The differential pressure sensor 313 is located at both ends of the second air pump 312. The main return pipe 307 connects the return tank 51 and the main tank 305.

[0067] In one embodiment, a first temperature sensor 310 and a second pressure sensor 303 are used to detect various states of water vapor in the main tank 305.

[0068] In one embodiment, the connection between the main return pipe 307 and the return tank 51 is at the bottom of the return tank 51, thus ensuring that the liquid returning to the main tank 305 is liquid.

[0069] Specifically, it also includes a third liquid pump, which is installed in the main return pipe 307. The third liquid pump can pump the liquid in the return tank 51 to the main tank 305.

[0070] In one embodiment, the main tank 305 further includes a liquid filling valve 304 and a liquid draining valve 306. The liquid filling valve 304 is used to add liquid into the main tank 305, and the liquid draining valve 306 is used to drain the liquid from the main tank 305.

[0071] In one embodiment, a second safety valve 302 is also provided on the main tank 305. When the second pressure sensor detects that the pressure inside the main tank 305 is too high, the second safety valve 302 opens to release pressure.

[0072] In one embodiment, the reflux tank 51 includes a secondary reflux pipe 54, which connects the heating unit 4 and the reflux tank 51. The connection heights of the first air inlet pipe 106, the secondary reflux pipe 54, and the main reflux pipe 307 to the reflux tank 51 are arranged to decrease sequentially. The advantage of this arrangement is that when the steam and liquid, after their temperature drops, enter the reflux tank 51, the liquid automatically flows to the bottom of the reflux tank 51 and can be directly sent to the main tank 305 through the main reflux pipe 307. The steam, due to its higher temperature, accumulates at the top of the reflux tank 51 and can be directly sent through the top.

[0073] In one embodiment, a replenishment valve 53 is provided on the reflux tank 51, which can be used to add liquid to the reflux tank 51.

[0074] It also includes the connection between the control system and the pipeline system via electrical signals, including but not limited to control methods such as PLC and microcontroller, and also includes detection module 903, analysis module 901, and control module 902;

[0075] The detection module 903 includes a first detection unit 904 and a second detection unit 905. The first detection unit 904 acquires the preset temperature, the values ​​read by the second temperature sensor 311 and the third temperature sensor 315 in real time to generate temperature information. The second detection unit 905 acquires the value of the second flow meter 314 and the value of the preset flow rate to generate flow information.

[0076] The analysis module 901 acquires temperature and flow information, calculates the temperature value of the main intake pipe 301 that needs to be increased or decreased and the steam flow rate that needs to be supplemented, and generates venting information containing control over the venting volume of each first air pump 111.

[0077] The control module 902 acquires the venting information and the reading of the first flow meter 110, controls at least one air pump to deliver air to the main air inlet pipe 301, and shuts down the first air pump 111 when the corresponding reading of the first flow meter 110 reaches the value in the venting information.

[0078] In one embodiment, when the analysis module 901 obtains temperature information, it compares the preset temperature with the value of the second temperature sensor 311. If the temperature of the second temperature sensor 311 is lower than the preset temperature, the generated venting information includes the following steps: (opening the corresponding first air pump 111 of the steam storage tank 107 with a steam temperature higher than the preset temperature until the value of the third temperature sensor 315 is equal to the preset temperature value); if the temperature of the second temperature sensor 311 is higher than the preset temperature, the generated venting information includes the following steps: (opening the corresponding first air pump 111 of the steam storage tank 107 with a steam temperature lower than the preset temperature until the value of the third temperature sensor 315 is equal to the preset temperature value).

[0079] In one embodiment, when the analysis module 901 obtains the flow information, it compares the value read by the second flow meter 314 with the preset flow rate (set according to the production heating requirements). If the value is less than the preset flow rate, the generated venting information includes the following steps: (When the gas storage tank 107 with the same steam temperature as the preset temperature still contains steam, the corresponding first air pump 111 is turned on. If the gas storage tank 107 does not contain steam, the first air pumps 111 corresponding to the gas storage tanks 107 with temperatures higher than and lower than the preset temperature are turned on simultaneously. The two steams are combined to ensure that the temperature of the steam entering the main air inlet pipe 301 is equal to the preset temperature, so that the flow rate detected by the first flow meter 110 is equal to the preset flow rate. The value of the differential pressure sensor 313 is obtained, and then the power of the second heater 210 is adjusted to increase the amount of steam generated until the pressure detected by the second pressure sensor 303 is equal to the original value plus the value of the differential pressure sensor 313).

[0080] In one embodiment, it further includes a heating module 906 and an adjustment module 907;

[0081] The heating module 906 includes acquiring the value of the fourth temperature sensor 102 and comparing the difference with the predetermined temperature value of the gas storage tank 107. If the difference is positive, a heating signal is generated; if the difference is negative, a cooling signal is generated.

[0082] The adjustment module 907 acquires a heating signal or a cooling signal and controls the corresponding first heater 204 to increase or decrease its power.

[0083] In one embodiment, a preset module is also included, which is used to set preset temperature, preset pressure, preset flow rate and other information.
