Special plane tail gas purification device for aerospace

Abstract

The invention discloses a special plane tail gas purification device for aerospace. The special plane tail gas purification device comprises a multilateral purification box, an end cover, a bottom cover and a hollow multilateral prism, wherein the end cover is rotationally arranged at one end surface of the multilateral purification box, the bottom cover is fixed at the other end of the multilateral purification box, the hollow multilateral prism fixed on the surface of the bottom cover is arranged in the center in the multilateral purification box, each division board is fixed between corresponding corners the hollow multilateral prism and the multilateral purification box, and a first filter screen layer, an activated carbon filter layer, a plant cleaning filter layer and a second filterscreen layer are arranged glidingly between the multilateral purification box and the hollow multilateral prism from the end cover to the bottom cover sequentially. The special plane tail gas purification device for aerospace is simple in structure and convenient to use, plane tail gas can be purified more effectively, air quality is guaranteed, the purification device is convenient to replace, and the construction cost is lower.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to an aircraft exhaust purification device dedicated to aerospace. Background technique [0002] Exhaust gas pollution refers to the pollution of the atmosphere caused by the exhausted exhaust gas caused by the incomplete combustion of motor vehicle fuel. Mainly: carbon monoxide, nitrogen oxides, hydrocarbons. Carbon monoxide is an intermediate product of hydrocarbon fuel combustion. It is mainly produced due to the incomplete combustion of hydrocarbons under local anoxic or low temperature conditions, and is mixed with the exhaust gas of the internal combustion engine and discharged. The emission of nitrogen oxides depends on factors such as combustion temperature, time and air-fuel ratio. From the combustion process, more than 95% of the nitrogen oxides emitted may be nitrogen monoxide, and the rest is nitrogen dioxide. No cases of humans being poisoned by nitric oxide have b...

Problems solved by technology

Due to its low solubility in water, it is not easy to be absorbed by the upper respiratory tract and penetrate deep into the lower respiratory tract and lungs, causing bronchitis, pulmonary edema and other diseases. In the contemporary era where environmental protection is increasingly advocated, further treatment of aircraft exhaust is required to ensure air quality. In addition to the further combustion of fuel, it is also necessary to purify the exhaust gas and then discharge it into the atmosphere. There are many types of purification devices and their quality is uneven, but most of the purification devices have incomplete purification. , due to the one-time injection of a large amount of exhaust gas, most of the exhaust gas will be discharged before purification, so a new technical means is needed to solve this problem, so that the exhaust gas purification is more thorough and the safety of the environment is protected
