[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; The temperature is the
indoor air temperature, so when the
outdoor temperature is higher than the indoor temperature, the outdoor
air temperature cannot be used as the initial temperature of the air in the cabin when the
thermal desorption starts, that is, the outdoor high-temperature air cannot be introduced into the cabin when the
thermal desorption starts , so that the initial temperature of the air in the cabin is consistent with the temperature of the high-temperature outdoor air, so when the
outdoor temperature is higher than the indoor temperature, the method that the initial temperature of the air in the cabin is the
indoor air temperature when the thermal desorption is started is now adopted, so that when desorption No energy saving; (3) Since the air valve at the top of the air purification chamber is opened in the blowdown mode, and the air valve at the bottom of the air purification chamber is closed, the desorbed
pollutant-containing air in the air purification chamber cannot be completely discharged. It may also be exhausted indoors, causing 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, the outdoor
fresh air cannot pass through the air. The filter module in the main body of the channel is purified and then introduced into the room, but directly into the room without being purified by the filter module; (5) Due to the use of pure timing
sewage discharge, 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. There may be a timed time that the heat in the
nacelle cannot be dissipated; ⑹ there is no dust removal function for the dust adsorbed on the coarse filter
