Dust collection equipment for textile printing and dyeing and dust collection method of dust collection equipment

Abstract

The invention discloses dust collection equipment for textile printing and dyeing. The dust collection equipment comprises a dust collection device, an organic gas absorption device, a cyclone separator and a fan A, and the cyclone separator and the fan A are fixedly arranged at the top of a cross beam; the dust collection device comprises a dust collection cylinder, an annular pipe and an air compressor; and the dust collection cylinder is arranged below the cross beam of a portal frame, a conical cylinder is fixedly arranged at the top of a straight cylinder, a small port of the conical cylinder upwards penetrates through the cross beam and is connected with an air inlet of the fan A through a pipe clamp, the straight cylinder is positioned right above a printing and dyeing wheel, an inner conical cylinder and a partition plate are welded in the straight cylinder, the partition plate is positioned below the inner conical cylinder, an exhaust fan is fixedly arranged on the bottom surface of each mounting hole, a fan B is connected to the small port of the inner conical cylinder through a pipe clamp, and a disc positioned in the conical cylinder is fixedly arranged at an air outletof the fan B. The dust collection equipment for textile printing and dyeing has the beneficial effects that the structure is compact, the dust collection effect is good, power loss of the cyclone separator is reduced and the organic gas absorption efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dust suction and dust removal in textile printing and dyeing production, in particular to a dust suction device and a dust suction method for textile printing and dyeing. Background technique [0002] The original meaning of textile is taken from the general term of spinning and weaving, but with the continuous development and improvement of the textile knowledge system and subject system, especially after the emergence of non-woven textile materials and three-dimensional composite weaving technologies, the current textile is not only a traditional Hand spinning and weaving also include garment, industrial and decorative textiles produced by non-woven technology, modern three-dimensional weaving technology, and modern electrostatic nano-netting technology. Therefore, modern textile refers to a multi-scale structure processing technology of fibers or fiber aggregates. Ancient Chinese textile and printing a...

Problems solved by technology

But this vacuum equipment still has the following defects: 1. The vertical height of the printing and dyeing station from the fan A (9) is long, causing the suction force at the lower port of the straight cylinder to be small, so that the dust and organic gas cannot be completely upwardly drawn. Go away, that is, part of the dust and organic waste gas stays in the lower port of the straight tube (13) and cannot be sucked up, which has the defect of poor dust suction effect

2. A large amount of dust is generated during the printing and dyeing process, so the cyclone separator (8) needs to consume a lot of power to complete the separation of dust and organic gas

3. There is a gap between the woven cloth (40) and the lower end surface of the straight cylinder (13), and the generated dust and organic gas are easy to leak from the gap, which not only reduces the dust collection effect of the fan, but also damages the lungs of the surrounding workers after leakage

4. Although the chemical agent sprayed from the spray system in the absorption tower can absorb the organic gas, but the flow rate of the chemical agent is too fast and the contact area is small, it takes a long time to completely absorb the organic gas, thus reducing the organic gas Processing efficiency
