[0023] The following will be combined with the embodiments of the present utility model Figure 1 to Figure 4 , the technical scheme, structural features, objectives achieved and effects in the embodiments of the utility model are described in detail.

[0024] It should be noted that the drawings are in a very simplified form and use non-precise proportions.

[0025] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0026] When processing high-temperature exhaust gas, the local scrubber converts the exhaust gas into acidic substances such as carbon dioxide and water vapor, and then sprays and cools it through the cooling chamber to form acidic water vapor. In order to solve the problem of excessive acidic water vapor generated by the current exhaust gas processor, the utility model proposes a condensing device, which is arranged in a water scrubber and connected to the water scrubber. The acidic water vapor first enters the water scrubber, and then enters the condensing device of this embodiment to be condensed, and after forming condensed water, it flows back to the water scrubber and finally flows to the water tank below the water scrubber, thereby reducing the acidic water vapor generated by the exhaust gas processor.

[0027] like Figure 1 As shown, the condensing device of this embodiment includes a condenser 2 and a plurality of refrigeration modules 3 arranged in the condenser 2. The lower end of the condenser has an inlet 1, which is connected to a water scrubber. Acidic water vapor is transmitted from the water scrubber to the condenser 2 through the inlet 1. In the condenser 2, part of the acidic water vapor is condensed to form condensed water, which flows back into the water scrubber from the inlet 1, and the uncondensed acidic water vapor is discharged from the top of the condensing device. A water tank is also connected to the bottom of the water scrubber, and the condensed water flowing back to the water scrubber continues to flow downward and enters the water tank.

[0028] There are multiple refrigeration modules 3, which are dispersedly arranged on the inner wall of the condenser 2. In this embodiment, the condenser 2 is rectangular, and multiple refrigeration modules 3 are dispersedly arranged on the four side walls of the condenser 2. The number of refrigeration modules 3 is 16-20, and the size of each is 4cm×4cm. In other embodiments, other numbers and sizes of refrigeration modules 3 can also be selected, so that the refrigeration modules 3 cover 10% to 50% of the inner wall of the condenser 2.

[0029] The refrigeration module 3 is a Peltier element, which is an element made by using the Peltier effect (thermoelectric cooling effect) and is composed of N-type and P-type semiconductor materials connected alternately. When direct current passes through the Peltier element, one side absorbs heat and the other side releases heat. In this embodiment, the heat-absorbing side is used to cool the acidic water vapor entering the condenser 2, so that the acidic water vapor becomes condensed water.

[0030] like Figure 2 and Figure 3 As shown, the principle of the Peltier effect is demonstrated. Each cooling module 3 has a first side 34 and a second side 35, and a pair of insulating sheets 36 and conductive sheets 37 are provided between the first side 34 and the second side 35. N-type and P-type semiconductor materials are provided between the two conductive sheets 37, and the conductive sheets 37 are connected to a DC power supply. When the power is turned on, the first side 34 absorbs heat and the second side 35 releases heat, so the first side 34 is a cooling side and the second side 35 is a heating side.

[0031] In this embodiment, the refrigeration module 3 is rectangular, the first side 34 faces the inside of the condenser 2, and the second side 35 is connected to the inner wall of the condenser 2. Acidic water vapor condenses to form condensed water under the action of the refrigeration side.

[0032] The second side 35 of the refrigeration module 3 releases heat. In order to avoid excessive temperature affecting the service life of the refrigeration module 3, a heat dissipation component is set on the second side 35 to dissipate heat. The heat dissipation component of this embodiment is a cooling water pipe, and process cooling water (PCW cooling water) flows in the cooling water pipe; the cooling water pipe passes through each of the refrigeration modules 3, and the cooling water pipe is set on the second side 35 of the refrigeration module 3.

[0033] like Figure 1 As shown, cooling water enters from the cooling water pipe inlet 5, passes through the cooling water pipes of multiple refrigeration modules 3, and flows out from the cooling water pipe outlet 7. The cooling water pipes of multiple refrigeration modules 3 may be interconnected or disconnected, and the present invention does not limit this.

[0034] The refrigeration module 3 is also connected to an external DC power supply 6. When the DC power supply 6 is connected, the refrigeration module 3 starts to work, and when the DC power supply 6 is disconnected, the refrigeration module 3 stops working. The current provided by the DC power supply 6 is adjustable, and the refrigeration temperature of the refrigeration module 3 can be controlled by adjusting the current.

[0035] The condensing device further comprises a temperature sensor, which is arranged in the condenser 2. It is used to measure the temperature in the condenser 2 so as to accurately adjust it. In this embodiment, the temperature sensor is arranged on the first side 34 of the refrigeration module 3. The temperature of the Peltier element is affected by the current and the temperature changes sensitively. By using the Peltier element as a refrigeration element, the temperature can be accurately controlled and the temperature adjustment speed is fast.

[0036] The condensing device further includes a controller, which is connected to the circuit of the refrigeration module 3 and can control the channel of the DC power supply 6 and the current provided by it to obtain a more accurate condensation temperature and effect. The controller is a DC power supply controller or a PLC (Programmable Logic Controller) module. In this embodiment, by controlling the current of the DC power supply 6, the temperature of the first side 34 is reduced to -15°C to condense the acidic water vapor.

[0037] To obtain better condensation effect, Figure 4 As shown, a plurality of transversely crossed aluminum pins 8 are arranged in the condenser 2, and the two ends of each aluminum pin 8 are respectively connected to a refrigeration module 3 on a certain side wall of the condenser 2 and the opposite side wall thereof, and the aluminum pin 8 is parallel to the cross section of the condenser 2. Specifically, the two ends of the aluminum pin 8 are respectively connected to the first sides 34 of the two refrigeration modules 3, so that the low temperature of the first sides 34 of the refrigeration modules 3 is quickly transferred to the aluminum pin 8, so that the temperature of the aluminum pin 8 is reduced, and at this time, the aluminum pin 8 also serves as the refrigeration side to condense the acidic water vapor; since the aluminum pin 8 is a dense structure and is parallel to the cross section of the condenser 2, the aluminum pin 8 has a certain damping effect on the flow of the acidic water vapor, thereby increasing the contact area and contact time between the refrigeration side and the acidic water vapor, improving the condensation efficiency, and reducing the acidic water vapor.

[0038] The condensed water generated by the condensing device flows back into the water scrubber, so the condensing device reduces the amount of acidic water vapor in the water scrubber, thereby reducing the acidic water vapor generated by the exhaust gas processor. The water scrubber and the condensing device can be connected by a C-type clamp, a clamp or other fixed connection methods.

[0039] In order to extend the service life of the condensing device, a polytetrafluoroethylene anti-corrosion coating is applied to the surface of the aluminum pin 8 and the inner wall of the condenser 2 to prevent corrosion by acidic water vapor.

[0040] After the above content, various modifications and substitutions of the utility model will be obvious. Therefore, the protection scope of the utility model should be defined by the attached claims.
