With the rapid development of industrialization in the past two years, haze weather has become more and more severe in our country. When haze or other air pollution occurs near the spinning workshop, the dust in the outdoor unclean fresh air used by the air conditioner has a large specific surface area, a small median diameter, a large surface energy, and there is an air film on the surface of the dust and water droplets. The air conditioning system The spray room cannot be washed out, and the fine dust will enter the spinning workshop.
Textile fibers are poor conductors of electricity. Fine dust is easily affected by static electricity and is adsorbed on the high-speed running bobbin. When the coverage area of the fine dust on the surface of the spun yarn exceeds a certain amount, This will cause the surface of the spun yarn to appear gray-black, and a large number of gray-black marks will appear on the surface of the gray fabric after weaving. This not only affects the appearance of the cloth, but is also difficult to remove during the bleaching and dyeing process. It can only be used to process dark gray fabrics, which limits the use of the yarn. scope, increasing printing and dyeing costs and causing great economic losses to enterprises.
(1) Pay close attention to the weather forecast and understand the atmospheric pollution situation in advance;
(2) Adjust the air conditioning system in a timely manner to ensure a slight positive pressure in the spinning workshop and prevent micro-organisms in the ambient air. Particulate matter enters the spinning workshop through the gaps in the maintenance structure. Specifically: reduce or not use fresh air, use more return air, ensure that the mechanical air supply volume of the spinning workshop is moderately greater than the mechanical exhaust volume of the workshop, and minimize the discharge of spinning floor exhaust to the outside. Wind and process exhaust to prevent negative pressure in the workshop from causing polluted air from outdoors or adjacent workshops to enter the spinning workshop;
(3) Use positive pressure purification equipment to effectively purify fine particles in the air. Increase the spray volume in the washing room, adjust the spray water temperature according to different conditions, and improve the air intake quality of the air conditioning system in the spinning workshop; use appropriate filters, such as multi-turn drum structures with large filtration area, high efficiency, low resistance, and compact structure. Can effectively filter fresh air.
It is worth noting that after the air conditioner uses a large amount of return air, the temperature of the workshop will increase. The air supply volume can be increased to reduce the temperature of the workshop; but at the same time, the humidity of the workshop will increase, so pay attention to whether there are rollers Tangled flowers and other related situations. In serious cases, the refrigeration unit should be turned on to provide low-temperature chilled water to facilitate cooling and dehumidification. </p
