Description

Toxin filtering box with excellent high-humidity environment performance

Technical Field

The utility model belongs to the technical field of toxin filtering boxes, and particularly relates to a toxin filtering box with excellent high-humidity environment performance.

Background

Many work environments may expose workers to contaminated air, such as environments of toxic and hazardous gases or vapors. In a toxic, hazardous gas or vapor contaminated work environment, workers may use respirators (respiratory protection equipment) to help reduce exposure. In general, respirators with repeatedly replaceable filter cartridges are the first choice in this work environment.

The poison filtering box is designed into a structure of a plastic box body with active carbon inside in most cases. The plastic box body is generally divided into a lower box body and an upper cover, and can be formed by injection molding and other processes. The activated carbon is filled in the lower box body and then is combined with the upper box body into a whole by ultrasonic wave or thermal bonding. The service life of the toxin filtering box is influenced by various factors, including the volume of the box body of the toxin filtering box, the adsorption performance of active carbon, the temperature and humidity of the use environment, the labor intensity of a user and the like. The humidity of the use environment is particularly significant for the service life of the poison filtering box for protecting the organic gas or steam. The poison filter cartridge for protecting the organic gas or vapor is generally packed in the cartridge body using a general activated carbon such as coconut activated carbon as an adsorption material, which adsorbs the organic gas or vapor molecules in the voids of the activated carbon by a physical adsorption mechanism. However, physical adsorption also acts on water vapor molecules, so that water vapor and toxic and harmful vapor or gas to be adsorbed are subjected to competitive adsorption, and the effective service life of the poison filtering box for organic gas or vapor to be protected is influenced. Research shows that when the relative humidity of the use environment is higher than 85%, the influence of the water vapor in the air on the effective adsorption performance of the activated carbon is greatly increased, so that the service life of the organic gas or vapor poison filtering box is greatly shortened, and the service life of the poison filtering box can be shortened to 50% or more of the normal condition for certain specific gases or vapors, such as benzene, toluene and the like. At this time, the user needs to increase the replacement frequency of the poison filtering box to maintain the normal protection requirement, so that the replacement cost of the poison filtering box is increased by times.

The users of the organic gas or vapor poison filtering box are spread over different environment areas in China, and can meet seasons with high humidity each year, so that the poison filtering box which can keep good service life in the high humidity environment can greatly reduce the use cost of the users or the using units, and meanwhile, the protection effectiveness of the poison filtering box can be better ensured.
