Waste gas treatment system and waste gas treatment method for setting machine

Abstract

The invention discloses a waste gas treatment system and waste gas treatment method for a setting machine and relates to the technical field of waste gas treatment. The waste gas treatment system for the setting machine comprises a first filtering device connected with an exhaust port of the setting machine, and a gas outlet end of the first filtering device is connected with a fluid suction inlet of an injection pump through a first fan; a working fluid inlet of the injection pump is connected with a liquid outlet of a circulating pump, a fluid outlet of the injection pump is connected with a liquid inlet in the bottom of an emulsification tank, an exhaust port in the top of the emulsification tank is connected with a second fan, and an overflow port in one side of the upper portion of the emulsification tank is communicated with an oil-water separator through an overflow pipe. An oil outlet of the oil-water separator is connected with an oil collecting tank, and a water outlet of the oil-water separator is connected with a liquid inlet of the circulating pump. The problems that an existing setting machine is large in waste gas treatment occupied area, multiple in equipment, high in energy consumption, prone to causing safety accidents such as fire disasters and low in purification efficiency can be solved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to an exhaust gas treatment system and an exhaust gas treatment method of a setting machine. Background technique [0002] During the weaving and dyeing process of textiles, in order to improve the appearance, appearance characteristics and dyeing quality of the product, it is necessary to add a variety of textile auxiliaries and solvents. A lot of moisture carried by dyed and rinsed textiles, together with organic compounds such as grease, wax and solvents, is heated and evaporated during high-temperature heat treatment in the setting machine, and is discharged together with the waste heat air to become waste gas. [0003] The exhaust gas of the setting machine is a mixed fluid containing gas-liquid-solid three-state pollutants. It has the characteristics of "high temperature, high humidity, oil content and complex composition", and its damage is very serious. The ou...
