Biomass windproof and dustproof device having volute-simulative helical structure

Abstract

The invention discloses a biomass windproof and dustproof device having a volute-simulative helical structure. The biomass windproof and dustproof device comprises a flexible windproof and dustproof mesh, a U-shaped support mesh plate, a biomass dust-blocking mesh, a top cover, a support base and a dust storage box. The dust storage box is installed in the support base. The flexible windproof and dustproof mesh is completely pasted to the inner surface of a middle plate of the U-shaped support mesh plate. The biomass dust-blocking mesh is pasted to the end surfaces of two side plates of the U-shaped support mesh plate so that a through hole structure is formed. The upper and lower ends of the through hole structure are respectively connected to the top cover and the support base through positioning screws. The middle plate of the U-shaped support mesh plate is provided with a plurality of small through holes. The biomass dust-blocking mesh is provided with a volute helical through hole. The device utilizes biomass corn stalk fibers as raw materials. Through combination of the volute helical through hole and an enclosed space structure and increasing of particle collision probability, particles in dust-containing gas flows can be filtered and adsorbed so that secondary pollution of particle pollutants is effectively prevented.

Description

technical field [0001] The invention relates to a biomass windproof and dust suppression device with a helical structure imitating a volute, and belongs to the technical field of atmospheric environmental protection implementation. Background technique [0002] At present, with the rapid development of livestock and poultry breeding industry, various ventilation technologies such as longitudinal ventilation have been widely used in order to discharge harmful substances such as dirty air in livestock and poultry houses, but this has also brought a series of serious environmental problems. The dirty air discharged from livestock and poultry houses contains a large amount of harmful substances, including pathogenic microorganisms, dust and odorous compounds, among which dust particles (PM) will spread bacteria, viruses, odorous substances and harmful gases, and will spread when the relative air humidity is lower than When 70% of the time, haze is formed, which will cause seriou...

Problems solved by technology

[0003] The existing windproof and dust suppression devices usually achieve the purpose of reducing the concentration of particulate matter in the air by reducing the speed of dust-laden airflow and increasing the collision between particles, reducing their kinetic energy and finally settling to the surface; but these particles have not It can be completely removed, and it will be used as a new dust source to generate secondary pollution if it encounters a strong current; a small part of the dust suppression net has a certain ability to absorb and remove particulate matter, but it is very easy to saturate, and cannot concentrate on the absorbed particulate matter; windproof The through-hole structure of the dust suppression net is single, and most of them are straight-line through-holes. Relatively simple
