Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to waste gas environmental protection treatment equipment. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. These gases may come from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The composition of waste gas is very complex and may include carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid mist, lead, mercury, beryllium, smoke and production dust. In order to avoid environmental pollution caused by direct emission of waste gas, it is necessary to use waste gas treatment equipment to treat the waste gas before discharging it.

When the exhaust gas temperature is too high, it will also affect the adsorption effect of the activated carbon layer.

[0005] To this end, we proposed an environmentally friendly waste gas treatment equipment. Utility Model Content

The threaded rod 14 is threadedly connected in the sleeve rod 13. The motor 15 drives the threaded rod 14 to rotate, which is beneficial to the use of the device. The bracket 12 is set to a triangle, and the scraped smoke and dust impurities are conveniently dropped into the ash collecting chamber 8 through the bracket 12. An air intake pipe 4 is fixedly installed at the right end of the filter box 2 corresponding to the filter chamber 9, and an exhaust pipe 7 is fixedly installed at the bottom end of the adsorption box 3.

[0023] Working principle: When in use, the exhaust gas enters the filter chamber 9 through the air inlet pipe 4, and the smoke and dust in the exhaust gas are filtered through the filter plate 10. Then, when the exhaust gas passes through the cooling pipe 16, the cooling water can be used to absorb heat and evaporate, and the exhaust gas can be quickly cooled down. Then, the exhaust gas is discharged into the liquid medicine in the medicine tank 18, so that the exhaust gas and the liquid medicine can fully contact and react, and the excess gas will float out of the liquid medicine.
