Plant ash preparation device with waste gas purification function

Abstract

The invention relates to the related field of waste gas purification, and discloses a plant ash preparation device with a waste gas purification function, which comprises a main box body; a combustion chamber with a rightward opening is arranged in the main box body, the right end surface of the main box body is hinged with a baffle plate positioned on the right side of the combustion chamber, and the upper end wall of the combustion chamber is communicated with a collection cavity; filter bags are fixedly connected between the left end wall and the right end wall of the smoke removal cavity, the contact area of lime slurry and waste gas is increased by spraying atomized lime slurry, so that the desulfurization efficiency is improved, nitric oxide in the waste gas is adsorbed by moving an activated carbon plate in a reciprocating mode to achieve denitration, and the denitration efficiency is improved. The plant ash waste gas is subjected to desulfurization and denitrification treatment, so that the environment is protected; in addition, nitric oxide in the waste gas is subjected to automatic induction treatment, then activated carbon is automatically replaced, it is guaranteed that nitric oxide in the waste gas is absorbed, and the effectiveness of the device is improved.

Description

technical field [0001] The invention relates to the related field of exhaust gas purification, in particular to a plant ash preparation device with exhaust gas purification function. Background technique [0002] Plant ash is generally prepared directly by burning straw and other crop dry materials, but the combustion of crops will produce a large amount of harmful gases such as smoke, sulfur dioxide and nitrogen oxides, which seriously pollute the environment. The effect of desulfurization and denitrification methods is average. Among them, the method of using activated carbon to adsorb nitrogen oxides often results in incomplete denitrification of exhaust gas due to the amount of nitrogen oxides that can be adsorbed by activated carbon, which reduces the effect of denitrification. Contents of the invention [0003] The object of the present invention is to provide a plant ash preparation device with exhaust gas purification function, which can overcome the above-mentione...

The effect of desulfurization and denitrification methods is general, and the method of using activated carbon to adsorb nitrogen oxides often results in incomplete denitrification of exhaust gas due to the fixed amount of nitrogen oxides that can be adsorbed by activated carbon, which reduces the effect of denitrification
