High-temperature mixed waste gas treatment device for agricultural production

Abstract

The invention discloses a high-temperature mixed waste gas treatment device for agricultural production. The device comprises a cooling device, a purification device and an oil-water separating device, wherein the cooling device comprises a cooling tank; the cooling tank is provided with a water inlet end opening and a water outlet end opening; the cooling tank is internally provided with a spiral vent pipe; the air inlet end of the vent pipe extends outside the interior of the cooling tank, and then air outlet end of the vent pipe is connected with an air inlet of the purification device and a liquid inlet of the oil-water separating device respectively by a three-way pipe; the purification device comprises a tank; the top in the tank is provided with a spray head; the oil-water separating device comprises a transparent separating tank; the bottom of the separating tank is provided with a drain pipe which is provided with a control valve; the side wall of the separating tank is provided with an oil discharge hole. After the high-temperature mixed waste gas treatment device is used, purification and separation of mixed waste gas as well as recycling of resources can be realized at the same time, so that economic and environmental benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste gas treatment, in particular to a high-temperature mixed waste gas treatment device used in agricultural production. Background technique [0002] As we all know, wastes in agricultural production such as wheat straw, corn stalk and rice straw, etc., in order to use these biomass fuels, pyrolysis furnace or cracking furnace are usually used for decomposition and gasification, and the high-temperature mixture generated after decomposition by the pyrolysis furnace Exhaust gas contains a lot of harmful acid gases, such as sulfur dioxide, etc., and there are organic components in the mixed exhaust gas, which can be used to extract light oil, gasoline, diesel and other available resources. Usually, the high-temperature mixed exhaust gas is directly discharged into the atmosphere , or sent to the adsorption tower for treatment, which will pollute the air on the one hand and cause a waste of r...
