Problems solved by technology

But the disadvantage is that all kinds of filters need to be replaced regularly due to adsorption saturation, and secondary pollution is easily generated after saturation. At the same time, the adsorption performance of the filters is affected by the water vapor in the air and the adsorbent itself, and the actual purification effect is limited.

Abstract

The invention discloses an indoor harmful gas removing device based on a low-temperature cold source. The indoor harmful gas removing device based on the low-temperature cold source comprises a loop formed by a heat exchanger, an adsorber and the low-temperature cold source, and further comprises an air pipeline, wherein an air inlet of the air pipeline is connected with a gas inlet of the heat exchanger; and a cold end outlet of the heat exchanger is connected with an air outlet of the air pipeline. Condensation or freezing temperatures of various harmful foreign gases in air are different, the various harmful foreign gases are condensed, frozen or adsorbed at low temperature in the heat exchanger and the adsorber, so that harmful gases such as formaldehyde, nitrogen oxide and volatile organic compounds in the indoor air are removed, and the purpose of purifying the air is achieved. In a regeneration process of the device, the gases are discharged safely, conveniently and fast, and secondary pollution cannot be caused.

Description

technical field [0001] The invention relates to the technical field of harmful gas purification, in particular to the technical field of an indoor harmful gas removal device based on a low-temperature cold source. Background technique [0002] From the analysis of indoor air quality in my country, the main sources of indoor air pollutants are building and interior decoration materials, outdoor pollutants, combustion products and human activities. Among them, the pollution of interior decoration materials and furniture is the main aspect that causes indoor air pollution, such as formaldehyde, toluene, ammonia, VOCs, etc., and a very small amount can cause great harm to human health. [0003] In daily life, people can use low-cost methods such as displacement ventilation, placing green plants or activated carbon in the home environment to remove harmful gases, but they can only be used as an inefficient auxiliary measure. In comparison, professional air purifiers are more wid...
