System for collecting spinning printing and dyeing volatile gas

Abstract

The invention discloses a system for collecting spinning printing and dyeing volatile gas. The system is characterized in that a gas collecting cover is arranged right above a volatile gas emission source, downward blowing is carried out from the periphery of the gas collecting cover to form a closed airflow wall, and the volatile gas emission source is arranged in the closed airflow wall. Meanwhile, the gas collecting cover is illuminated through lamplight, the drying effect is improved, and gas volatilization is facilitated. The system further relates to two following parallel working procedures to achieve single work or combined work. A, a support on the periphery of a net frame where the printing gas is emitted in a concentrated mode is designed to be hollow, negative pressure is formed, and then the volatilized gas is collected and gathered into a gas collecting pipe; B, a framework of a scraping and printing frame lifting mechanism is of a hollow structure and is provided with a plurality of negative-pressure gas sucking holes, and the gas on a guide band face on the periphery of the net frame is sucked in and gathered into the gas collecting pipe. The system for collecting the spinning printing and dyeing volatile gas has the advantages that the waste gas collecting function is achieved; the function of preventing the pollution and waste gas from being diffused is achieved; the energy saving function is achieved.

Description

technical field [0001] The invention relates to a process flow, in particular to a textile printing and dyeing volatile gas collection system. Background technique [0002] At present, textile printing enterprises are faced with the compression of sewage discharge indicators, energy-saving transformation and the introduction of the "Exhaust Gas Emission Standards for the Textile Printing and Dyeing Industry" that will be issued within this year. Especially, the requirements for environmental protection are becoming more and more stringent. will be shut down. Many places in the country have shut down some printing and dyeing enterprises, and moved some large-scale printing enterprises into the printing and dyeing (flower) parks planned by the government, but mainly to solve the problem of sewage discharge and treatment. Next, all textile printing and dyeing industries will face strict regulations. The requirements of exhaust gas emission standards, most companies in the indu...

Problems solved by technology

[0003] In production processes such as sizing machines and textile printing, a lot of waste gas will be produced due to the volatilization of colorants and additives. Exhaust gas pollution will cause pungent and unpleasant gas in the workshop, which seriously affects the health of printing workers in the workshop. At the same time, the pollution Unorganized and untreated waste gas is directly discharged, which is easy to pollute the air and does not meet environmental protection requirements
