Description

Technical Field

[0001] The invention belongs to the technical field of dust removal and return air, and relates to a return air system, in particular to a dust removal and return air system. Background Art

[0002] Traditional return air equipment can adjust the indoor air circulation through fans. However, in the production workshops of some woven products such as fabrics, traditional return air equipment cannot meet the needs of such production workshops. Such production workshops not only need ventilation to maintain air circulation in the production workshops, but also need to remove the debris and some dust generated in the production process to prevent affecting the quality of the products. At the same time, there are certain requirements for factors such as temperature and humidity in the production workshop. Therefore, in order to simultaneously meet the control of dust removal, return air, temperature and humidity and other factors, it is necessary to design a dust removal return air system.

[0005] The return air device includes an air pump 2, a filter, a temperature regulator and a humidifier. The air pump 2 is connected to an air outlet through an air inlet pipe. The air outlet is arranged in a workshop. The air inlet pipe is connected to a dust inlet pipe through a return air pipe. A valve 3 is installed on the return air pipe. The filter and the temperature regulator are installed on the air inlet pipe in sequence. The humidifier is connected to the air inlet pipe through a humidifying pipe, and the interface between the humidifying pipe and the air inlet pipe is located between the temperature regulator and the filter.

[0006] The working principle of the present invention is as follows: start air pump one and air pump two, and use air pump one to suck the debris and dust generated by the workshop production into the dust inlet through the collection port. At this time, valve one is opened and valve two is closed. The dust enters the dust removal device through the dust inlet pipe for collection and dust removal. After the dust removal is completed, the air is discharged through the air outlet pipe, and valve three is opened at the same time. The old air passes through the return air pipe and is mixed with the new air drawn in by air pump two in the air inlet pipe. It is first filtered by the filter, and then the temperature regulator and humidifier are adjusted to adjust the temperature and humidity of the filtered air. Finally, it enters the workshop through the air outlet to maintain air circulation and air pressure balance in the workshop. When the workshop stops production operations and only needs to maintain air circulation in the workshop, valve one is closed and valve two is opened. The air in the workshop passes through the dust inlet pipe and is directly discharged from the air outlet pipe two.

[0007] The humidifier comprises a water vapor generator and a water tank, the water outlet of the water tank is connected to the humidifying pipe, the water vapor generator is installed at the water outlet, and the water inlet of the water tank is connected to the water inlet pipe.

[0010] With the above structure, impurities in the fresh air drawn into the air pump and dust in the old air in the return air duct are filtered through the filter element and the filter screen, ensuring clean air coming out of the air outlet.

[0011] The dust removal device includes a shell, a filter dust removal unit and an electrostatic dust removal unit. The shell can be divided into two parts, A and B. A plurality of slots are arranged inside the A part. The filter dust removal unit is installed in the A part. The filter dust removal unit is composed of a plurality of dust filters. Both ends of the dust filters are clamped in the slots of the A part of the shell. The dust filters are placed at an angle and are parallel to each other. The aperture of the filter holes on the dust filters gradually decreases from the dust inlet. The side plate of the shell is rotatably installed on the shell through a rotating shaft. The B part is installed with an electrostatic dust removal unit. The electrostatic dust removal unit includes a plurality of electrostatic generating plates and a fixing frame. The electrostatic generating plates are horizontally installed inside the dust removal device and fixed by the fixing frame.

[0012] By adopting the above structure, in the filter dust removal unit, the dust in the air can be filtered out and guided to the dust outlet pipe through the inclined filter, and the filters arranged parallel to each other are selected with different apertures, so that the dust can be filtered in layers, and the detachable card slot structure is convenient for replacing the dust filter; in the electrostatic dust removal unit, some lighter and smaller dust can be collected by the electrostatic generating plate, so as to further enhance the dust removal effect, and the openable side panel installed on the side of the shell is convenient for the installation and maintenance of the filter dust removal unit and the electrostatic dust removal unit in the shell.

[0013] A grid plate is installed on the collecting port.

[0014] With the above structure, the grid plate is placed on the ground, so that dust can pass through while workers and transport vehicles can pass on it.

[0015] An isolation plate is installed at the dust inlet.

[0016] The above structure is adopted to prevent debris from falling into the dust inlet pipe and causing blockage.
