Embodiment Construction

[0008] It will be described in detail below in conjunction with the accompanying drawings.

[0009] The ozone generator (1) produces high-concentration ozone gas, which enters the gas-liquid mixing pump (2) through the suction line (5), and the gas-liquid mixing pump (2) absorbs ozone gas while absorbing water from the water storage tank (3) , through pressurized mixing in the pump, the ozone gas is efficiently dissolved in the water to obtain high-concentration ozone water. The high-pressure ozone water is directly injected into the bleaching reaction tank (4) (dyeing tank) by the pump, and kept in the reaction tank (4) ( Dyeing vat) with a water pressure of 1.5~2.5kgf / cm2, so that the yarn to be bleached is completely immersed in high-pressure, high-concentration ozone water, and the ozone water is continuously circulated, and ozone is continuously added to maintain the concentration of the ozone water. Since dyes are organic chemicals, a large amount of ozone will be consum...

Abstract

The invention discloses a yarn ozone bleaching device and bleaching method. The yarn ozone bleaching device comprises an ozone generator, a gas-liquid mixing pump, a water storage tank, a bleaching reaction tank, a suction pipeline, a circulation pipeline, a sampling port and a pressure gage. The method includes the steps that high concentration ozone gas is prepared through the ozone generator, the ozone gas enters the gas-liquid mixing pump through the suction pipeline, the gas-liquid mixing pump absorbs the ozone gas from the water absorption side of the water storage tank, the ozone gas is efficiently dissolved in water in a pump inside pressurization mixing mode, so that high concentration ozone water is obtained, the high pressure ozone water is directly injected into the bleaching reaction tank through the pump, yarns to be bleached are completely soaked into the high pressure and high concentration ozone water, the ozone water is circulated continuously, ozone is added continuously, and the concentration of the ozone water is kept. The yarn ozone bleaching device and bleaching method have the advantages that pollution-free ozone bleaching is conducted on the yarns, after bleaching is completed, the ozone water can still be recycled after purification treatment, and the purpose of energy saving and emission reduction is effectively achieved.

Description

Technical field [0001] The invention belongs to dyeing and finishing equipment and a dyeing and finishing process in the textile industry, and in particular relates to a yarn ozone bleaching device and a yarn bleaching method. Background technique [0002] At present, known yarn bleaching mainly uses hydrogen peroxide, sodium hydroxide, and brighteners for bleaching treatment, so that the cost of sewage treatment is too high and the environment is seriously polluted. Contents of the invention [0003] In order to overcome the shortcomings of existing yarn bleaching, such as high cost of sewage treatment and serious environmental pollution, the present invention uses an ozone generator to continuously add ozone to maintain the concentration of ozone water, and use high-concentration and high-pressure ozone water to treat the yarn. Bleach treatment. [0004] The technical scheme of the present invention is realized in the following way: it comprises an ozone generator, a ga...
