- the gas collecting heater uses an infrared lamp tube to heat the surface of the object and promote the volatilization of harmful gases inside the object.
- the ultraviolet lamp can not only promote the decomposition of formaldehyde, but also Sterilize the surface of the object to remove microbial contaminants.
- the harmful gases volatilized and the dust and air near the objects will pass through the hood through the hose into the tubular air handling unit.
- the air treatment unit is divided into an air layer and a filter layer.
- the inhaled air is blown obliquely into the barrel along the wall of the tube to form a cyclone.
- the bottom end of the barrel contains a small amount of water, which accelerates the sedimentation of particles and objects with large gravity and dissolves in the water. Then the gas will pass through the coarse filter (except large particles), HEPA filter (dust removal, sterilization), activated carbon filter (adsorption of harmful gases and odors such as formaldehyde) and cold catalyst filter (decomposed formaldehyde, from bottom to top). After treatment, benzene, xylene, toluene, TVOC and other harmful gases are treated and humidified and discharged into the room.
- the filter screen for removing harmful gases has two layers: an activated carbon filter and a cold catalyst filter. Considering that the concentration of harmful gases in the air is high, the adsorption effect of the activated carbon filter cannot meet the requirements of air quality, so a cold catalyst filter is added. That is to avoid the occurrence of secondary pollution, and improve the purification effect. It will undergo a catalytic reaction under normal temperature conditions, from simple physical adsorption to chemical adsorption, decomposing toxic and odorous harmful gases into harmless and odorless water and carbon dioxide, and the cold catalyst after the reaction does not change, Long-term function, greatly extending the service life of the adsorbent material.
- the humidifier can automatically monitor the relative humidity in the environment.
- the humidifying function is set at the exhaust port, and the air purified from the water tank to the air cap is sprayed with water vapor, thereby achieving the purpose of humidification and avoiding moisture on the filter.

- the UV lamp can be used to sterilize the surface of the object and decompose some harmful gases.
- Infrared lamps can be used to heat the surface of objects and promote the volatilization of internal harmful gases.
- the bottom of the gas collecting hood is equipped with rolling pulleys, which saves labor and labor. Harmful gases volatilized on the surface of the object, dust from the floor, and indoor air can be transported to the air purification unit through the hood and hose. The airflow is tangentially blown into the inner side of the cylinder wall through the air inlet, causing the airflow to spirally move, and larger objects and particulate matter are deposited and dissolved in the bottom water.
- the airflow then passes through the filter screen for layer-by-layer filtration.
- the first step is the coarse filter at the bottom. It mainly filters out hair, fiber fluff, large particles, dander, etc. in the indoor floor and air. Then passes the high efficiency HEPA filter. It can effectively remove inhalable particulate matter, cigarette smoke, pollen and bacteria in the air. It is then passed through an activated carbon filter, which has high adsorption performance. It can be used to remove volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene and airborne pollutants. It can also deodorize and remove odors, and has good purification. effect.
- the residual formaldehyde, ammonia, TVOC, hydrogen sulfide and other harmful gases in the residual air react with oxygen to form water and carbon dioxide.
- the activated carbon filter alone cannot meet the air quality requirements, so a two-layer filtration facility is used.
- the airflow passes through the trapping action of the gas gathering, the water vapor content is lowered, the air is relatively dry, and the requirements for human comfort are not satisfied.
- the treated air is subjected to humidification measures, and pure water is added to the annular water tank, and the moisture is sprayed into the air cap through the humidifier, and the amount of the humidifier sprayed can be determined by the relative humidity in the indoor air. Automatic adjustment.
- the filtered and humidified air is discharged into the room through the exhaust port, and the air is continuously circulated to continuously purify the indoor air.
- the gas collecting heater uses an infrared lamp tube to heat the surface of the object and promote the volatilization of harmful gases inside the object.
- the ultraviolet lamp tube When using the ultraviolet lamp tube, it can not only promote the decomposition of formaldehyde, but also the surface of the object. Sterilize and remove microbial contaminants.
- the harmful gases volatilized and the dust and air near the objects will pass through the gas collecting hood through the hose to the cylindrical air treatment unit.
- the air treatment unit is divided into an air layer and a filter layer.
- the inhaled air is blown obliquely into the barrel along the wall of the tube to form a cyclone.
- the bottom end of the barrel contains a small amount of water, which accelerates the sedimentation of particles and objects with large gravity and dissolves in the water. Then the gas will pass through the coarse filter (except large particles), HEPA filter (dust removal, sterilization), activated carbon filter (adsorption of harmful gases and odors such as formaldehyde) and cold catalyst filter (decomposed formaldehyde, from bottom to top). After treatment, benzene, xylene, toluene, TVOC and other harmful gases are treated and humidified and discharged into the room.
