Technical Field
The invention relates to the field of environmental protection and purification, in particular to a chemical fiber spinning circular blowing waste gas circulating and concentrating system.
Background
At present, with the improvement of environmental protection requirements, the reduction treatment and the reduction emission of harmful substances in organic waste gas become the key points for the reconstruction and expansion projects and new projects and for solving the problems of low-cost treatment and reduction emission of organic waste gas.
The air quantity required by fiber cooling in the chemical fiber production is the largest part in the whole fiber production process. The air with certain temperature and humidity purified by the spinning air conditioner enters a fiber cooling device (a short fiber circular blowing system), and after passing through the cooling device, if no waste gas collection device exists, the air flow is discharged along with the tows and directly discharged into the large air. The directly discharged gas usually contains oligomers (monomer, dimer, trimer and tetramer, mainly trimeric cyclic oligomer) separated out from the polyester during the cooling process of the polyester and smoke (especially the recycled colored waste polyester textile serving as the spinning raw material) appears, so that the operation environment is influenced, and the environment is greatly influenced. How to collect, treat and recycle the waste gas generated in the fiber production process is the key to solve the production environment and reduce the emission of organic waste gas.
At present, the majority of short fiber cooling processes are in the form of fiber cooling devices with external blowing, and fiber cooling devices for a small part of melt direct spinning or chip spinning adopt an internal central blowing mode, but all have closed collection of gas after fiber cooling (external blowing carries out air draft through an interlayer stack arranged on the stack, and central blowing can carry out air draft through closing spinning and winding floors). Generally, after the fiber sprayed from the polyester melt at 285 +/-10 ℃ is cooled by 22 +/-2 ℃ air, the air temperature at the center of the filament bundle can be as high as 60 +/-5 ℃, and the temperature of hot air collected from a shaft even if the hot air is mixed with other waste air can be above 50 ℃. Compared with the air-conditioning air supply volume, the collected air volume is 1.2 to 1.3 times of the volume of the air-conditioning air supply volume (mainly the thermal expansion of air).
