Problems solved by technology

[0007] As we all know: adopting heating desorption to adsorbent material is the method generally adopted by those skilled in the art, in order to overcome the defect that the adsorption type purifier needs to frequently replace the adsorbent material, and according to the method of adsorbent material heating desorption, currently there are public literature records to collect heat A new type of adsorption purifier with desorption function integrated, such as the patent application number: 201510898501.0, a wall-mounted air purifier based on thermal regeneration and its purification method. Users can choose indoor purification or mechanical ventilation according to their needs. When choosing When the indoor purification function is used, the sewage will be discharged after thermal desorption during the working process. When the mechanical ventilation function is selected, the outdoor fresh air will be introduced into the room. However, the wall-mounted air purifier and its purification method have the following defects: When it is attached (heat regeneration mode period), the pressure in the closed airtight cabin may be too high, and because the pressure relief valve for preventing device damage is installed on the wall of the air purification room of the airtight cabin of the purifier to the room, once the pressure is released When the valve is opened to release the pressure, the air with high concentration of pollutants in the cabin will be released to the room, causing secondary pollution in the room, and when the air valve between the air purification room and the heating regeneration room is closed and the heating regeneration room leads The outdoor air valve is closed, that is, when the purifier is in the purification mode, the heating control circuit of the electric heating wire in the heating and regeneration chamber loses control and generates high temperature, and the temperature sensor in the heating and regeneration chamber is damaged. At this time, the closed heating and regeneration chamber generates The pressure may be too high and damage the device, because the pressure relief valve installed on the wall of the air purification room facing the room cannot work at this moment; (2) the dust adsorbed on the coarse filter cannot be discharged to the outside; (3) due to the sewage mode The air valve at the top of the air purification room is opened at the bottom, and the air valve at the bottom of the air purification room is closed, so the desorbed pollutant-containing air in the air purification room cannot be completely discharged, and may be discharged into the room. Form secondary pollution; (4) Since the air valve at the bottom of the air purification room is opened in the fresh air mode, and the air valve at the top of the air purification room is closed, it is impossible for the outdoor fresh air to be purified by the filter module in the main body of the air duct Introduced into the room, but directly into the room without purification by the filter module; (5) Due to the use of pure timing sewage, the timing time may be too long or too short, such as the timing time may be too long in winter, and the timing time may be too short in summer The heat in the cabin can't dissipate

Embodiment Construction

[0035] Such as figure 1 As shown, a wall-mounted air purifier based on thermal regeneration includes: a closed cabin 1, a fan 2, the first electronically controlled air valve 3 to the fifth electronically controlled air valve 7, a coarse filter 8, and high-efficiency renewable VOCs And formaldehyde adsorption material 9, heating element 10, VOCs sensor 11, first temperature sensor 12, second temperature sensor 16, control processor unit 13, pressure relief valve 14; The VOCs sensor 11, first temperature sensor 12 and the second Two temperature sensors 16 are respectively connected with the input ends of the control processor unit 13; end connected.

[0036] The coarse-effect filter 8 and high-efficiency renewable VOCs and formaldehyde adsorption material 9 constitute an air purification module; the coarse-effect filter 8 is a conventional product that is convenient to install, and the present invention selects a traditional filter screen, which is mainly used for purifying pa...

Abstract

The invention discloses a wall-mounted type air purifier based on thermal regeneration and a purifying method of the wall-mounted type air purifier. The purifier comprises a sealed cabin which is divided into a left-right heating regeneration chamber and an air purifying chamber, a VOCs sensor, a two-way fan, an efficient regenerative VOCs and formaldehyde adsorption material and a low efficient filter which are sequentially mounted in the air purifying chamber from top to bottom as well as a heating body, a first temperature sensor and five air valves for controlling an air flue, which are sequentially mounted in the heating regeneration chamber from top to bottom. The purifier is characterized by further comprising a pressure relief valve which is mounted on a cabin wall of the heating regeneration chamber and communicates with the outdoor through a through wall, and a second temperature sensor which is mounted indoors for measuring a temperature; the pressure relief valve is enabled to be capable of releasing pressure when too high cabin pressure is caused by any-time temperature out of control, and secondary pollution is not formed indoors. According to the method disclosed by the invention, at a sewage disposal stage of a purifying mode and in a fresh air mode, an air direction of a fan is changed for enabling the low efficient filter to discharge ash to the outdoor; and a timing and temperature measuring method is adopted to control sewage disposal time length, so that a temperature in the cabin is enabled to be adaptive to the indoor temperature after sewage disposal is ended.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, and in particular relates to a structural design of a wall-mounted air cleaner based on heat regeneration and a purification method thereof. Background technique [0002] With the rapid development of urbanization in our country, the number of new buildings is huge every year, and more and more new decoration materials and chemical products are used in interior decoration. These new interior decoration materials often release a large amount of pollutants such as volatile organic compounds (VOCs) and formaldehyde, causing serious indoor pollution. According to statistics, after decoration, most of the formaldehyde and VOCs content in newly built houses exceeds the standard. [0003] Volatile organic compounds (VOCs) and formaldehyde significantly affect people's comfort, health and work efficiency. Volatile organic compounds cause sensory stimulation to the human body, make the h...
