As shown in fig. 1 to 7, in order to implement the first embodiment of the present invention, the combustion tower may be applied to the treatment of waste gas generated in a solar cell sintering furnace or a passivation furnace, and may also be applied to the treatment of waste gas generated in other industrial manufacturing processes. The box body is connected with a waste gas discharge outlet of the solar cell sintering furnace or the passivation furnace, so that waste gas in the furnace can be introduced into the box body for purification treatment.

Specifically, the box includes the cooling box 7 that is located the upside and is located the burning box 1 of downside, and waste gas is from after burning through burning box 1 cooling through cooling box 7, finally arranges to the environment to reduce environmental pollution, also can show the temperature that reduces the operation, provide comparatively suitable operation environment for the operation personnel.

In this embodiment, in order to reduce the influence of high-temperature exhaust gas on the periphery of the cooling box 7, a heat insulating layer is further arranged in the cooling box 7, the heat insulating layer surrounds the cooling chamber 71, and generally, the heat insulating layer can be made of foam.

The condenser 72 has a condensing tube 721 extending in a curved manner and disposed in each cooling chamber 711, and fins 722 extending from the condensing tube 721 to the periphery. The condenser tube 721 has a plurality of straight tube portions arranged in an array and curved tube portions connecting adjacent straight tube portions, wherein the straight tube portions extend in a front-to-rear direction along a horizontal direction. In this embodiment, the fins 722 are formed by extending the straight tube portion to the periphery, and by providing the fins 722, the heat transfer area can be increased, which is advantageous for accelerating the conduction of the high temperature of the exhaust gas into the tube and the removal of the exhaust gas by the cooling water, thereby accelerating the cooling effect.

When the straight tube portions are arranged in an array, the partition plates 76 may be disposed between two adjacent rows of straight tube portions in the height direction or between two adjacent rows of straight tube portions in the transverse direction, so that the arrangement of the partition plates 76 may be adjusted according to the positional relationship between the cooling box 7 and the combustion box 1 in actual production.

The condenser tubes 721 of the adjacent cooling chambers 711 are also communicated with each other through the bent tube portions, so that the condenser 72 has an inlet and an outlet as a whole, and the bent tube portions of the condenser tubes 721 communicating with the adjacent cooling chambers 711 are inserted into the air vents 13. The vent 13 is made by the structure of the bent pipe portion, and has a simple structure, which does not obstruct the assembly of the partition 76, and facilitates the circulation of exhaust gas.

The flare further includes a flow control valve 74 disposed at the water inlet of the condenser tube 721. In order to accelerate the cooling efficiency, cooling water is generally introduced into the condenser 721, and the cooling water absorbs the temperature of the exhaust gas and becomes normal temperature water, which is also convenient for reuse, and the flow rate of water may be increased by controlling the flow rate control valve 74, thereby further accelerating the cooling.

The combustion tower further includes an exhaust device disposed at a rear side of the exhaust port 73, the exhaust device having an outer cover 75 disposed on the cooling box 7, a fan (not shown) disposed in the outer cover 75 to draw the exhaust gas and discharge the exhaust gas out of the cooling chamber 71, the exhaust port 73 being disposed at one side of the cooling box 7 in the transverse direction and disposed at a rear side wall of the cooling box 7. A thermocouple (not shown) is also provided within the housing 75 to sense the temperature of the exhaust gas therein, and when the temperature reaches the discharge temperature, the exhaust gas is discharged, and when the temperature is higher than the discharge temperature, the flow rate of the water in the condenser 72 is controlled to increase the temperature reduction.

As shown in fig. 2 to 5, in the present embodiment, the number of the partition plates 76 is 1, and the partition plates 76 are disposed between two adjacent rows of the condensation pipes 721 extending in the height direction, and the thickness of the partition plates 76 in the transverse direction is extremely thin in order to reduce the volume of the cooling box 71 occupied by the partition plates 76.

The air vent 13 is disposed adjacent to the right side wall of the cooling chamber 71, the air outlet 73 is disposed adjacent to the left side wall of the cooling chamber 71, and the air outlet 73 is disposed on the rear side wall of the cooling chamber 71 and abuts the lower side wall and the left side wall. Of course, in other embodiments, the air vent 13 may be disposed adjacent to the left side wall of the cooling chamber 71, and the air vent 73 may be disposed adjacent to the right side wall of the cooling chamber 71.

In this arrangement, when the exhaust gas enters the cooling chamber 71 from the air vent 13, the exhaust gas flows upward along the rightmost side of the right cooling chamber 711, flows into the left cooling chamber 711 through the communication port 761, and flows downward until the exhaust gas is discharged from the exhaust port 73 to the cooling box 7. Thereby, the circulation path of the exhaust gas in the cooling chamber 71 is extended, the cooling time is increased, and the cooling effect is improved.

In this embodiment, the communication port 761 may be formed by the partition 76 being spaced apart from the upper inner wall or the lower inner wall of the cooling chamber 71. The communication port 761 may be provided near the upper inner wall or the lower inner wall of the cooling chamber 71 so as to penetrate the partition plate 76 in the lateral direction.

Of course, in order to further improve the cooling effect, the number of the partition plates 76 may be increased, and the communication ports 761 of the adjacent partition plates 76 are arranged in a vertically staggered manner, so that the exhaust gas may flow in the cooling chamber 71 in a "W" shape, and further, the cooling time of the exhaust gas may be increased, thereby reducing the exhaust gas temperature. It should be emphasized that, instead of the path of the exhaust gas being "W" shaped, it is meant that the exhaust gas will repeatedly flow back and forth until it exits the cooling tank 71, as to what shape the actual path of the exhaust gas will take, depending on the number of baffles 76, e.g., the path is "U" shaped when there is only one baffle 76, and "S" shaped when there are two baffles 76.

And, when the number of the partitions 76 is an odd number, the exhaust port 73 is provided on the rear side wall of the cooling chamber 71 adjacent to the lower side wall, and when the number of the partitions 76 is an even number, the exhaust port 73 is provided on the rear side wall of the cooling chamber 71 adjacent to the upper side wall.

In this embodiment, the number of the exhaust ports 73 is two, and the exhaust ports are respectively disposed on the left and right sides of the cooling chamber 71, so that the high-temperature exhaust gas entering the cooling chamber 71 flows to the left and right sides respectively and is then exhausted from the exhaust ports 73 on the left and right sides, and therefore, the temperature around the cooling box 7 is relatively low, and the influence of the surface temperature of the cooling box 7 on the surrounding wire harness is reduced.
