An automatic discrimination and switching double-filter textile workshop air purification system

Abstract

The present invention discloses an air purification system for a textile workshop with a double filter screen that automatically discriminates and switches, including a filter air duct, an intake air duct, and an exhaust air duct. The intake air duct and the exhaust air duct are respectively arranged at both ends of the filter air duct. Inside the filter air duct, there are a PP cotton filter element and a glass filter element made of glass fiber, and the PP cotton filter element and the glass filter element can be selectively switched inside the filter air duct. By setting the switchable PP cotton filter element and glass filter element, the filter element can be selectively switched according to the environment and actual needs, effectively solving the respective defects of the two filter elements. By monitoring environmental factors, when the environmental factors do not affect the PP cotton filter element, the PP cotton filter element is selected for air purification, and the wind speed of the intake fan is correspondingly reduced to achieve the energy-saving effect of daily use. When it is monitored that the environmental factors affect the PP cotton filter element, the glass filter element is switched and selected, and the wind speed of the intake fan is correspondingly increased to filter in a complex environment to protect the service life of the PP cotton filter element.

Description

Technical Field

[0001] The present invention is applied to the field of air purification, and specifically relates to an air purification system for textile workshops with automatically discriminative switching of double filters. Background Art

[0002] Air purification technology is widely used in production and life. For example, there is a lot of dust in textile workshops. If the air in the workshop is not purified and filtered, the workers in the workshop will directly inhale the dust, which will cause great harm to their physical health. The commonly used filter elements in the existing technology include two types: PP cotton filter elements and glass filter elements, each with its own advantages and disadvantages. The PP cotton filter element has good filtering effect, but its service life is affected by environmental factors. When it is in an environment with high humidity or high concentration of oil particles, the electrostatic adhesion on its surface will be reduced or even eliminated, resulting in the loss of its filtering ability; the glass filter element has good filtering effect and is not easily affected by environmental factors, but its gas passing ability is poor and it needs to be used in conjunction with a high-power fan with strong wind force, consuming a large amount of energy during operation.

The monitoring component includes a humidity monitoring module 7 for monitoring the humidity in the air and a fume concentration monitoring module 8 for monitoring the concentration of oil particles in the air. In the middle section of the filter air duct 1, there is a sealing frame 9. The PP cotton filter element 4 and the glass filter element 5 are respectively arranged on both sides of the sealing frame 9, and installation frames 10 are respectively provided corresponding to the PP cotton filter element 4 and the glass filter element 5 on both sides of the sealing frame 9. The PP cotton filter element 4 and the glass filter element 5 are both arranged on the installation frames 10. One end of each installation frame 10 is rotationally connected to the inner wall of the filter air duct 1 through an ear plate, and the installation frame 10 is controlled by a control motor to rotate relative to the ear plate. When the installation frame 10 rotates to be perpendicular to the axis of the filter air duct 1, it is in the working state. When the installation frame 10 rotates to be parallel to the axis of the filter air duct 1, it is in the storage and switching state. At one end of the installation frame 10 away from the control motor, there is a first adsorption magnet. Corresponding to the first adsorption magnet on both sides of the sealing frame 9, there are second adsorption magnets. When the installation frame 10 is in the working state, the first adsorption magnet and the second adsorption magnet adsorb each other to fix the installation frame 10 in the working state. On both sides of the PP cotton filter element 4 and the glass filter element 5, there are clamping blocks 11. The installation frame 10 is provided with sliding grooves 12 corresponding to the clamping blocks 11. The clamping blocks 11 are engaged with the sliding grooves 12 to complete the detachable connection between the PP cotton filter element 4 or the glass filter element 5 and the installation frame 10.

[0029] During the use process, the PP cotton filter element 4 is greatly affected by the air humidity, and its performance will be irreversibly affected in humid weather. Therefore, how to increase the air flow rate on the surface of the PP cotton filter element 4 to prevent it from getting damp in humid weather, or how to quickly remove the moisture just adsorbed on its surface has become a technical problem to be solved in this field. This solution can use the drying fan 16 to work to suck away the moisture on its surface through the air box 15, the one-way valve, and the air holes 14, which extends the service life of the PP cotton filter element 4 to a certain extent.
