Problems solved by technology

The fiber filter has high resistance and obvious noise, and the filter needs to be replaced regularly, which is costly
Secondary pollutants will be generated in the process of electrostatic dust removal
[0006] At present, the conventional thermophoresis air filter device lacks the control of the air outlet temperature, and the air temperature generated by many air treatment devices after thermophoresis is relatively high. When used in summer, the comfort of the human body is poor.

Embodiment Construction

[0015] The following is attached figure 1 , 2 Embodiments of the present invention will be described in detail.

[0016] Such as figure 1 As shown, at first, open the air pump 2, the air enters the air intake pipe 3 from the air inlet 1, and a check valve 4 is installed behind the air pump 2 to prevent the liquid 5 in the scrubber 6 from sucking back into the air pump, causing damage to the air pump. The liquid 5 in the scrubber 6 can be ordinary tap water, gel, oily liquid, etc., which can be selected according to requirements. The air enters the scrubber 6 using liquid as the adsorption filter medium, which can dissolve hydrophilic pollutants, adsorb hydrophobic pollutants, pass the air with particles through the liquid, and increase the moisture content in the gas phase. The agglomeration of particles is accelerated, and the size of small particles becomes larger after agglomeration, which is conducive to sedimentation, and the surface tension of the liquid is used to lo...

Abstract

The invention discloses a thermophoresis air filtering device which comprises three parts, namely an air washing device, a thermophoresis treatment device, a temperature control device. Air to be treated is fed into the air washing device with a liquid for primary filtration through an air pump; the air is fed into the thermophoresis treatment device later; thermophoresis pipelines are S-shaped and are connected through thermal insulating flanges; a low reflection thermal insulating plate is inserted between adjacent parallel pipelines; finally filtered air enters a temperature control device to be heated or cooled to a required temperature, and the heated or cooled air is discharged out from an air discharge hole. The thermophoresis air filtering device is environment-friendly, efficient, good in comfort, and convenient to disassemble, wash and maintain.

Description

technical field [0001] The invention belongs to the field of air conditioning and purification, and in particular relates to a device for removing particulate matter in the air by utilizing thermophoretic effect. Background technique [0002] In recent years, smog weather has frequently appeared in many areas of our country. The smog is mainly caused by various human activities. The economic and social activities of high-density population will inevitably emit a large amount of particulate matter. Once the emission exceeds the atmospheric circulation capacity and carrying capacity The concentration of fine particles will continue to accumulate, and if affected by the calm weather at this time, large-scale smog will easily appear. [0003] Smaller diameter particles in the air can directly enter the bronchi and even the lungs through the respiratory system, causing respiratory diseases, cerebrovascular diseases, nasal cavity inflammation, obstructive emphysema and even lung c...
