Description

Technical Field

[0001] The present application relates to the technical field of tail gas treatment, and in particular to a condensing device for tail gas treatment. Background Art

[0002] Tail gas generally refers to the waste gas emitted from the production process of the petroleum, petrochemical, chemical and other industries, as well as the waste gas generated by combustion activities such as automobiles, factories, and power plants. It contains various harmful substances, such as volatile organic compounds (VOCs), carbon dioxide, carbon monoxide, nitrogen oxides, particulate matter, etc. The accumulation of these harmful substances in the atmosphere will cause air pollution and harm human health and the environment. Therefore, measures such as reducing tail gas emissions, improving combustion efficiency, and adopting clean energy have become important means to deal with environmental pollution and climate change;

[0003] Generally, in the process of tail gas treatment, after the tail gas is washed to remove impurities such as acid, alkali, sulfur, and particulate matter, it needs to be condensed to reduce pollution to the environment.

[0004] At present, when the tail gas is condensed, the tail gas after the water washing method is usually discharged into a condensing device to be condensed into liquid, and then discharged to the next process through a drain port;

[0005] However, only one condenser is used in the condensation process. Since the water content in the tail gas after the water washing method is high, after entering the condenser, the interior is in a low temperature and high humidity environment for a long time, which causes frost inside. Therefore, it is necessary to defrost and clean the interior, but it needs to be shut down for cleaning, and it cannot be cleaned in real time, thereby reducing its working efficiency.

[0006] Therefore, it is necessary to provide a condensing device for tail gas treatment to solve the above problems.

[0007] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a condensing device for exhaust gas treatment to achieve the effect of using multiple condensers.

[0010] Furthermore, the cleaning component includes an evaporator fixedly mounted on a frame, and a first shunt pipe is provided on the evaporator together with liquid outlets of the first condenser and the second condenser.

[0011] Furthermore, a second shunt pipe is provided between one end of the evaporator and the interiors of the first condenser and the second condenser.

[0013] Furthermore, the merging assembly includes a merging pipe disposed on the first condenser and the second condenser, and the merging pipe is connected to the exhaust pipe.

[0014] The beneficial effect of the present application is that a condensing device for exhaust gas treatment provided by the present application can form a dual channel for condensation treatment during condensation through the setting of the condensation component, that is, when one condenser is working, the other condenser can be defrosted or on standby, thereby achieving the effect of using multiple condensers.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1 As shown, the present application provides a condensing device for exhaust gas treatment, including a frame 1, and a condensing assembly 2 is arranged on the frame 1, and the condensing assembly 2 is used for condensation treatment of exhaust gas;

[0026] like Figure 1-Figure 2 As shown, the condensation assembly 2 includes a first condenser 21 fixedly mounted on the frame 1, and a second condenser 22 fixedly mounted on the frame 1, and an air intake shunt pipe 26 is provided on the first condenser 21 and the second condenser 22, and one end of the air intake shunt pipe 26 away from the first condenser 21 is connected to an external water washing tower, and the air intake shunt pipe 26 controls the flow of the pipeline through two groups of first valves (not shown in the figure), so as to facilitate the exhaust gas to be introduced into the first condenser 21 or the second condenser 22;

[0027] The first condenser 21 and the second condenser 22 are both provided with a liquid inlet 23 and a liquid outlet 24, so that the refrigerant can circulate under the drive of the compressor. At the same time, the first condenser 21 and the second condenser 22 are both provided with a drain port 25, so as to discharge the condensed liquid.

[0028] The tail gas is introduced into the first condenser 21 through the air intake shunt pipe 26 for condensation, and finally the condensed liquid is discharged to the next process through the drain port 25. At this time, the second condenser 22 can be defrosted or on standby;

[0029] Meanwhile, a cleaning component 3 is arranged on the frame 1, and the cleaning component 3 is used to clean the condensation component 2;

[0030] like Figure 1-Figure 2 and Figure 4 As shown, the cleaning assembly 3 includes an evaporator 34 fixedly mounted on the frame 1, and a first shunt pipe 31 is provided on the evaporator 34 and at the liquid outlets 24 of the first condenser 21 and the second condenser 22, and the first shunt pipe 31 controls the flow of the pipeline through two sets of second valves (not shown in the figure), and a second shunt pipe 32 is provided at one end of the evaporator 34 and inside the first condenser 21 and the second condenser 22, and the second shunt pipe 32 controls the flow of the pipeline through two sets of third valves (not shown in the figure);

[0031] At the same time, an exhaust pipe 33 is provided at the other end of the evaporator 34, and the exhaust pipe 33 controls the circulation of the pipeline through a fourth valve (not shown in the figure), and the end of the exhaust pipe 33 away from the evaporator 34 is connected to the input end of the compressor. It should be noted that the liquid inlets 23 of the first condenser 21 and the second condenser 22 are connected to the output end of the compressor through a liquid inlet shunt pipe (not shown in the figure), and the circulation of the pipeline is controlled by two sets of liquid inlet valves on the liquid inlet shunt pipe to form a complete cycle of the refrigerant;

[0032] When the first condenser 21 is in the condensing working state, the refrigerant at its liquid outlet 24 is introduced into the evaporator 34 through the first shunt pipe 31 controlled by the second valve for evaporation, and the evaporated high-temperature gas is introduced into the second condenser 22 through the second shunt pipe 32 controlled by the third valve for defrosting. After the defrosting is completed, the third valve closes the second shunt pipe 32, and the fourth valve opens the exhaust pipe 33, connecting the compressor with the exhaust pipe 33 to complete the circulation of the refrigerant. On the contrary, when the second condenser 22 is working, the first condenser 21 can be defrosted.

[0033] It should be noted that, in order to prevent the dehumidification time from being too long, after a period of dehumidification, the third valve closes the second shunt pipe 32, and the gas inside the evaporator 34 opens the exhaust pipe 33 through the fourth valve to flow back to the compressor, so as to complete the refrigerant circulation work;

[0034] At the same time, a merging component 4 is provided on the cleaning component 3, and the merging component 4 is used for the merging operation of the refrigerant;

[0035] like Figure 3-Figure 4As shown, the confluence assembly 4 includes a confluence pipe 41 disposed on the first condenser 21 and the second condenser 22, and the confluence pipe 41 is connected to the exhaust pipe 33, and the confluence pipe 41 controls the pipeline flow through a fifth valve (not shown in the figure);

[0036] When the defrosting operation is performed, such as when the second condenser 22 is defrosted, the refrigerant gas evaporated by the evaporator 34 inside is introduced into the exhaust pipe 33 through the fifth valve opening confluence pipe 41, so that it flows back to the compressor and the compressor completes the complete refrigerant cycle;

[0037] To sum up, when the exhaust gas is treated, the exhaust gas enters the first condenser 21 in the condensation component 2 from the air intake component and is discharged through the drain port 25. During this process, the refrigerant is discharged into the cleaning component 3 through the liquid outlet 24 to evaporate, and is discharged into the second condenser 22 to defrost the interior. The gas inside it merges through the merging component 4 and enters the exhaust pipe 33 to form a circulation with the compressor.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
