An alkali liquor control system

Abstract

The invention provides an alkali liquor control system comprising a first production apparatus, a weak alkali liquor collection device, a filter device, a normal concentration configuration unit, a supplementing alkali liquor source, and a second production apparatus. With the structural design of the whole system, the effect of low-cost operation is achieved, collected weak alkali liquor and commercial alkali can be mixed to prepare alkali liquor with a required concentration effectively according to production requirements and the alkali liquor can be conveyed to a specified production machine bench automatically. With the system, weak alkali liquor can be recovered and utilized to the greatest extent and low-cost operation is achieved.

Description

technical field [0001] The invention relates to the field of chemical equipment for textile printing and dyeing, in particular to an lye control system. Background technique [0002] For pure cotton printing and dyeing production lines, caustic soda is the main auxiliary agent for pretreatment, and the cost of use accounts for nearly 40% of the cost of pretreatment auxiliary agents. The mercerizing machine is the machine with the largest proportion of caustic soda consumption (usually, the caustic soda consumption of the mercerizing machine accounts for about 80% of the total caustic soda consumption), and the main component of the waste water it produces is 35-45g / L light lye. If the waste water containing light lye is not recovered, in addition to the increase in the cost of additives, if the sewage is directly discharged, it will take a large amount of acid agents such as sulfuric acid for neutralization. In this way, not only will the operating cost be increased, but al...
