[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model adopts a second air inlet pipe to surround the cooling water pipe to cool the exhaust gas. In order to ensure that heat energy is not wasted, the water will continue to be heated for employees to use while cooling the exhaust gas. However, when the employees do not use hot water, in order to continue to cool the exhaust gas, a cooling pump will be used to cool the hot water and then recirculate it into the water tank. In order to thoroughly filter the exhaust gas, an activated carbon layer, a ceramic layer, a gravel layer and a volcanic stone layer are used, which can not only filter the sulfur dioxide in the exhaust gas but also filter out the odor simultaneously, which is very convenient.

[0016] 2. The utility model uses a filter to filter particles in the exhaust gas to prevent the particles from clogging the opening for a long time, affecting the exhaust gas from being discharged from the second exhaust pipe, and to prevent the filter from being clogging for a long time. A slide plate and a slide rail are provided to cooperate with each other to take out the filter for replacement. In order to prevent exhaust gas leakage, a sealing gasket is fixed on one side of the door panel to isolate the exhaust gas from the outside. The device has a simple structure and is very efficient.
