[0002] With the rapid development of industrialization, various industrial smoke pollution problems are becoming increasingly serious, causing great harm to the environment and human health. In order to solve this problem, smoke exhaust gas purification devices came into being. Smoke exhaust gas purification devices are a kind of high-efficiency air purifier designed for industrial exhaust gas smoke and dust. The structure is a complete air purification system composed of dust collection pipes, high-efficiency filters, activated carbon filters, special dust collection fans and touch-type microcomputer controllers. It is widely used in machinery, hardware, electronic appliances, optoelectronics, chemicals, tobacco, pharmaceuticals, food, biology and other industries and other places with smoke, smoke and dust pollution.

It needs to be disassembled and cleaned frequently, which is quite troublesome. At the same time, some smoke also contains high heat, which not only affects the adsorption capacity of the activated carbon filter element, but also directly discharges it, which is a waste of energy.

After the water level drops to a certain amount, the floating plate 18 of the bottom buoyancy water level detection assembly begins to drop, thereby driving the slide bar 16 and the pressure plate 15 to drop, so that the pressure plate 15 is close to the travel switch 17. When the pressure plate 15 contacts the travel switch 17, it means that the lowest water level has been reached. When the water level rises to the set value, the floating plate 18 of the top buoyancy water level detection assembly rises accordingly, and the floating plate 18 drives the pressure plate 15 to approach the travel switch 17 through the slide bar 16 until it contacts the travel switch 17, which means that the highest water level has been reached.

[0022] A plurality of waste heat filter water chambers 12 are sequentially provided inside the shell 1 from bottom to top, a fixed air pipe 9 is fixedly connected between the heating filter water chamber 6 and the adjacent waste heat filter water chamber 12 and between two adjacent waste heat filter water chambers 12, a water storage chamber 14 is provided at the inner top of the shell 1, a water outlet pipe 10 is fixedly connected between the heating filter water chamber 6 and the inner tops of the plurality of waste heat filter water chambers 12, and the water outlet pipe 10 is respectively connected with the waste heat filter water chamber 12 and the water storage chamber 14 at the top thereof, and the plurality of water outlet pipes 10 are installed with solenoid valves, and when water needs to be added, the setting of the solenoid valve is conducive to controlling the opening and closing of the water outlet pipe 10.

[0023] An exhaust gas filter assembly is fixedly installed on one side of the outer surface of the shell 1, and the exhaust gas filter assembly includes an outlet pipe 13, and the outlet pipe 13 and the shell 1 are fixedly connected, the bottom of the outlet pipe 13 is fixedly penetrated by the outer shell 2, and the outer shell 2 and the shell 1 are fixedly connected, the inside of the outer shell 2 is fixedly connected with an activated carbon filter element 11, and the bottom of the outer shell 2 is fixedly penetrated by a fan 3, and the gas filtered by water enters the outer shell 2, and then is purified by the activated carbon filter element 11, and finally discharged through the fan 3.

[0024] An air intake pipe 4 is fixedly connected to one side of the outer surface of the shell 1, and the air intake pipe 4 passes through the shell 1 and extends to the interior of the heating and filtering water chamber 6.

When the temperature sensor 8 detects that the water temperature in the heating and filtering water chamber 6 reaches the set value, it is discharged through the drain pipe 5 for utilization. After the water level drops to a certain amount, the floating plate 18 of the bottom buoyancy water level detection component begins to drop, thereby driving the slide bar 16 and the pressure plate 15 descends, so that the pressure plate 15 approaches the travel switch 17. When the pressure plate 15 contacts the travel switch 17, it means that the lowest water level has been reached. At this time, drainage is stopped, and then the water outlet pipe 10 is opened through the solenoid valve. The water in the water storage chamber 14 and the waste heat filtration water chamber 12 falls in turn. At this time, the water level in the heating and filtration water chamber 6 begins to rise. When the water level rises to the set value, the floating plate 18 of the top buoyancy water level detection component rises accordingly. The floating plate 18 drives the pressure plate 15 to approach the travel switch 17 through the slide bar 16 until it contacts the travel switch 17, which means that the highest water level has been reached. At this time, each solenoid valve closes the water outlet pipe 10, and then replenishes the water storage chamber 14 with water through the water inlet pipe and the external water supply equipment until the set amount is reached.
