The bottom of the first regenerative chamber 60 is fixedly connected to the top of the support table 5. The bottom of the automatic valve mechanism 61 is fixedly connected to the top of the support table 5. The inner surface of the fixing plate 62 is fixedly connected to the outer surface of the automatic valve mechanism 61, and the bottom of the fixing plate 62 is fixedly connected to the top of the support table 5. The number of the ceramic regenerators 63 is two, and the outer surface of the ceramic regenerator 63 is fixedly connected to the inner wall of the first regenerative chamber 60.

The outer surfaces of two of the grids 67 are fixedly connected to the inner surface of the first regenerative chamber 60, and the outer surfaces of the other two grids 67 are fixedly connected to the inner surface of the second regenerative chamber 66.

[0027] By setting the regenerative combustion assembly 6, when the waste gas enters the first regenerative chamber 60 through the automatic valve mechanism 61 and reaches the combustion chamber 64, natural gas and oxygen enter the combustion chamber 64 through the burner 65 for combustion. The temperature of the combustion chamber 64 reaches about 760 degrees Celsius, and the waste gas is completely burned to produce carbon dioxide and water. Then it passes through the second regenerative chamber 66 and is discharged through the exhaust pipe 7. Some gases react under the action of high temperature to produce solid particles. The grid 67 intercepts these particles to prevent them from falling onto the surface of the ceramic regenerator 63, reducing the situation of blockage of the ceramic regenerator 63.

The outer surface of the first box body 30 is fixedly connected to the end of the pipeline 2.

The top of the second layer of filter screen 32 is fixedly connected to the inner surface of the first box body 30 and is arranged on the right side of the first layer of filter screen 31.

[0030] By setting the dust removal component 3, when the waste gas passes through the first layer of filter screen 31, particulate matter with a diameter greater than five microns is removed. When the waste gas passes through the second layer of filter screen 32, particulate matter with a diameter less than five microns is removed. The two-layer filtration can effectively remove the dust in the waste gas, thereby reducing the situation of dust clogging the ceramic regenerator 63 and improving the waste gas treatment efficiency.

[0031] Among them, the ammonia removal component 4 includes a second box body 40, a support frame 41, and an adsorption catalyst 42. The outer surface of the second box body 40 is detachably connected to the end of the pipeline 2.

The number of the adsorption catalysts 42 is several, and the bottom of the adsorption catalyst 42 is fixedly connected to the inner surface of the support frame 41.

[0032] By setting the ammonia removal component 4, when the waste gas passes through the support frame 41, the ammonia-containing gas in the waste gas reacts with the adsorption catalyst 42 in the support frame 41 and is adsorbed and retained in the adsorption catalyst 42. It can reduce the situation of ammonium salt aerosol generated by the reaction of ammonia-containing gas with other gases after combustion, effectively solve the problem of clogging of the ceramic regenerator 63, extend the service life of the ceramic regenerator 63, reduce losses, and improve the waste gas treatment efficiency.

[0033] Among them, the automatic valve mechanism 61 includes a first automatic valve 610, a first flow sensor 611, a controller 612, a second automatic valve 613, a third automatic valve 614, a second flow sensor 615, and a fourth automatic valve 616. The bottom of the first automatic valve 610 is fixedly connected to the top of the support platform 5. The first flow sensor 611 is arranged on the outer surface of the first automatic valve 610. The bottom of the controller 612 is fixedly connected to the outer surface of the support platform 5, and the controller 612 is electrically connected to the first flow sensor 611. The bottom of the second automatic valve 613 is fixedly connected to the top of the support platform 5. The bottom of the third automatic valve 614 is fixedly connected to the top of the support platform 5 and is electrically connected to the controller 612. The second flow sensor 615 is arranged on the outer surface of the third automatic valve 614. The bottom of the fourth automatic valve 616 is fixedly connected to the top of the support platform 5.

[0034] By setting up the automatic valve mechanism 61, initially, the automatic valve one 610 and the automatic valve two 613 are open, and the automatic valve three 614 and the automatic valve four 616 are in the closed state. The waste gas enters the first regenerator 60 through the automatic valve one 610, reaches the combustion chamber 64. Natural gas and oxygen enter the combustion chamber 64 through the burner 65 for combustion. The temperature of the combustion chamber 64 reaches about 760 degrees Celsius, completely burning the waste gas to produce carbon dioxide and water. The ceramic regenerator 63 is made of a material with a fast temperature rise and good temperature storage ability, and there are voids inside the ceramic regenerator 63 to allow gas to pass through. The burned gas passes through the second regenerator 66, transferring the temperature to the ceramic regenerator 63. The temperature of the ceramic regenerator 63 rises, and at this time, the gas temperature decreases. The cooled gas reaches the exhaust pipe 7 through the automatic valve two 613 and is discharged; when the gas flow reaches a certain level, the flow sensor one 611 feeds back the signal to the controller 612, and the controller 612 controls the automatic valve one 610 and the automatic valve two 613 to close, and the automatic valve three 614 and the automatic valve four 616 to open. The waste gas enters the second regenerator 66 through the automatic valve three 614, passes through the heated ceramic regenerator 63, the waste gas is heated up, reaches the combustion chamber 64 for combustion, and the burned gas passes through the first regenerator 60, transfers the temperature to the ceramic regenerator 63, and then reaches the exhaust pipe 7 through the automatic valve four 616 and is discharged; when the gas flow reaches a certain level, the flow sensor two 615 feeds back the signal to the controller 612, and the controller 612 controls the automatic valve one 610 and the automatic valve two 613 to open, and the automatic valve three 614 and the automatic valve four 616 to close. The waste gas enters the combustion chamber 64 through such a cycle, improving the treatment efficiency, while making use of the heat generated by combustion and reducing energy loss.

[0035] The working process of the present utility model is as follows:

[0036] First of all, the waste gas reaches the dust removal component 3 from the high-pressure induced draft fan 1 through the pipeline 2. When the waste gas passes through the first layer of filter screen 31, the particulate matter with a diameter greater than five microns is removed. When the waste gas passes through the second layer of filter screen 32, the particulate matter with a diameter less than five microns is removed. The two-layer filtration can effectively remove the dust in the waste gas;

[0037] Then, the waste gas passing through the dust removal component 3 reaches the ammonia removal component 4. When the waste gas passes through the support frame 41, the ammonia-containing gas in the waste gas reacts with the adsorption catalyst 42 in the support frame 41 and is adsorbed and retained in the adsorption catalyst 42, which can reduce the situation where the ammonia-containing gas reacts with other gases to form ammonium salt aerosols after combustion, effectively solve the problem of blockage of the ceramic regenerator 63, and extend the service life of the ceramic regenerator 63;

[0038] Finally, the exhaust gas enters the first regenerator 60 through the automatic valve mechanism 61 and reaches the combustion chamber 64. Natural gas and oxygen enter the combustion chamber 64 through the burner 65 for combustion. The temperature of the combustion chamber 64 reaches about 760 degrees Celsius, completely burning the exhaust gas to produce carbon dioxide and water. After passing through the second regenerator 66, it reaches the exhaust pipe 7 through the automatic valve two 613. In the entire exhaust gas treatment process, exhaust gases with high or low boiling points are all subjected to high-temperature combustion oxidation to produce harmless water and carbon dioxide for emission, achieving the result of disposing of the exhaust gas at one time.
