Multifunctional chemical defense filter absorber

Abstract

The invention relates to a multifunctional chemical defense filter absorber, and relates to the field of filter absorbers. The multifunctional chemical defense filter absorber comprises a housing, wherein a gas inlet end and a gas outlet end are arranged on the housing, an explosion-proof liner layer is arranged in the housing, an anti-impact turbulent flow assembly is arranged at the gas inlet end in the explosion-proof liner layer, an installing frame is arranged on the explosion-proof liner layer, an installing groove is formed in the installing frame, a filter element pipe groove with a serpentine structure is arranged on the installing groove, a plurality of filter screen layers are horizontally distributed in the filter element pipe groove, activated carbon layers are laid on the filter screen layers, a gas inlet pipe and a gas outlet pipe are arranged on the two ends of the filter element pipe groove, a sealing closed door is arranged on the side wall of one side of the filter element pipe groove, a sterilization assembly is arranged on the gas outlet end, when the multifunctional chemical defense filter absorber is vibrated, the horizontally arranged filter screen layers and the activated carbon layers are less affected, impact wave and air flow are reduced by arranging the anti-impact turbulent flow assembly, impact on the filter screen layers and the activated carbonlayers is reduced, dust in the air is uniformly accumulated on the filter screen layers, and the service life of the whole is not affected.

Description

technical field [0001] The invention relates to the field of filter absorbers, in particular to a multifunctional anti-chemical filter absorber. Background technique [0002] The civil air defense filter absorber is a special chemical defense equipment specially developed in accordance with the protection standards and protection requirements of civil air defense projects for chemical weapons. Biological aerosols, radioactive dust, persistent poison vapor and other harmful substances provide filtered clean air to the personnel in the project. The activated carbon plate is the core component of the civil air defense filter absorber, which can absorb various wartime poisons and reduce the toxicity threshold of wartime poisoned air. The activated carbon plate is filled with activated carbon, and the activated carbon must be evenly and densely packed in the activated carbon plate without leakage gaps. [0003] For example, a filter absorber disclosed in Chinese patent No. CN10...

AI Technical Summary

Problems solved by technology

[0004] But, there is following defect in above-mentioned technology: the activated carbon particle attached to its inclined carbon bed will fall during installation and use, and the impact of airflow is easy to shake off activated carbon particle, and the dust particle attached in the airflow is easy to get stuck on the inclined carbon bed. Accumulation, affecting filter performance
