A flow pipe 108 is fixedly connected to the surface of the support rod 106. A water pump 107 is fixedly connected to the surface of the flow pipe 108. A water storage tank 201 is fixedly connected to the surface of the flow pipe 108. A transport pipe 305 is fixedly connected to the surface of the water storage tank 201. A purification box 110 is fixedly connected to the surface of the transport pipe 305. A screen 304 is fixedly connected to the surface of the screen 304. The purification box 110 is fixedly connected to the surface of the transport pipe 305. 10. The inner surface of the purification box 110 is fixedly connected with a filter residue chamber 301, the upper surface of the filter residue chamber 301 is fixedly connected with a release ring 303, the upper surface of the release ring 303 is fixedly connected with a detection ring 210, the upper surface of the filter residue chamber 301 is fixedly connected with a detector 209, the lower surface of the filter residue chamber 301 is rotatably connected with a stirring fan 302, the surface of the transport pipe 305 is fixedly connected with a bottom frame 109, the surface of the bottom frame 109 is fixedly connected with a separation tank 104, and the inner surface of the separation tank 104 is fixedly connected with a temperature insulation device. Top 202, the inner surface of the separation tank 104 is fixedly connected with a tolerance wall 203, the surface of the tolerance wall 203 is provided with a primary filter groove 204, the surface of the insulation top 202 is fixedly connected with a purification column 205, the surface of the purification column 205 is fixedly connected with a buckle 206, the surface of the purification column 205 is fixedly connected with a separation disk 207, the surface of the transport pipe 305 is fixedly connected with the waste box 105, the surface of the transport pipe 305 is fixedly connected with a branch pipe 306, and the surface of the branch pipe 306 is fixedly connected with a purification box 110.

[0020] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that the interior of the primary filter tank 204 is a solid groove of an industrial reducing agent, which can reduce the industrial waste gas flowing out of the metallurgical device 101, and the ring buckle 206 is medical stone, which can continue to roughly purify the industrial waste gas after liquefaction, and then pass through the separation plate 207 for solid-liquid separation, and the liquid flows into the transport pipe 305 at the lower end of the separation tank 104 and enters the purification box 110, and the solid particles formed after the industrial waste gas is reduced enter the transport pipe 305 connected to the upper end and flow into the waste box 105, and part of the liquid enters the waste box during the separation process 105, the liquid can enter the purification box 110 through the transport pipe 305 connected to the surface of the waste box 105. After the liquid enters the purification box 110, the water source monitored by the detector 209 will start the filter chamber 301 to rotate and drive the stirring fan 302 to rotate synchronously. The upper surface of the filter chamber 301 is activated carbon particles, which can absorb impurities in the water source, and the release ring 303 will release aluminum chloride to purify the water. At this time, the detection ring 210 monitors the water body. After meeting the daily water use requirements, the water source can flow into the water storage tank 201 through the screen 304 for daily use.

[0021] According to the above working process, it can be known that the industrial waste gas generated by metallurgy can be reduced through the separation tank 104, and the reduced solid particles can enter the waste box 105 through the transport pipe 305 to achieve a recycling effect, and the water source in the water storage tank 201 can be pumped out by the water pump 107 when the equipment is started and flows into the temperature-resistant water pipe 208 to achieve the purpose of cooling the metallurgical device 101. While the metallurgical device 101 is cooled, the water absorbs heat, and the water body enters the purification box 110 during the flow process. After the water is purified, the water body meets the daily use needs and flows out from the screen 304 through the transport pipe 305 into the water storage tank 201.

[0022] This solution has the following working process: after the metallurgical device 101 completes metallurgy, the water pump 107 is started, and the room temperature water source in the water storage tank 201 enters the temperature-resistant water pipe 208. After the water source absorbs the heat of the temperature-resistant water pipe 208, it enters the purification box 110 through the waste box 105. The detection ring 210 monitors the entry of the water source and starts the filter residue chamber 301. The filter residue chamber 301 drives the stirring fan 302 to flow the water source. At this time, the activated carbon on the upper surface of the filter residue chamber 301 absorbs impurities in the water, and the release ring 303 releases alumina to purify the water. The detection ring 210 detects the water source. After reaching the daily water use standard, the air pressure chamber 103 stabilizes the overall air pressure of the equipment during this process, and the industrial waste gas enters the separation tank 104 and is reduced through the primary filter tank 204. The separation plate 207 is used to separate the solid and liquid water to achieve the implementation of waste heat recovery and waste gas treatment.

[0023] In summary: the industrial waste gas generated by metallurgy can be reduced through the separation tank 104, and the reduced solid particles can enter the waste box 105 through the transport pipe 305 to achieve the recycling effect, and the water source in the water tank 201 can be pumped out by the water pump 107 and flow into the temperature-resistant water pipe 208 when the equipment is started to achieve the purpose of cooling the metallurgical device 101. While the metallurgical device 101 is cooled, the water absorbs heat, and the water body enters the purification tank 110 during the flow process. After the water is purified, the water body meets the daily use needs and flows out from the screen 304 through the transport pipe 305 into the water tank 201. The separation tank 104, the purification tank 110, the water tank 201, the transport pipe 305, etc. are all made of heat-resistant and heat-insulating materials to minimize heat loss. The internal components of the separation tank 104, such as the insulation top 202, the tolerance wall 203, the primary filter tank 204, etc. are all corrosion-resistant components.
