Mercerized weak waste alkali recycling and utilizing device

Abstract

The invention provides a mercerized weak waste alkali recycling and utilizing device. A recycling cylinder is arranged to recycle weak waste alkali, the bottom of the recycling cylinder is provided with a filter screen to roughly filter and remove large particulate matter, the recycling cylinder is provided with a discharge pipe to be connected with a transition cylinder, the transition cylinder is connected with a master outlet pipe, the two sides of the recycling cylinder are provided with a first overflow cylinder and a second overflow cylinder, the transition cylinder is connected to the first overflow cylinder to prevent the recycling cylinder and the transition cylinder from overflowing, both the first overflow cylinder and the second overflow cylinder are connected to the master outlet pipe, and the master outlet pipe is connected with a discharge pump to convey the weak waste alkali to a next plant. Meanwhile the top inside the recycling cylinder is provided with a liquid level sensor, when the liquid level sensor senses that the liquid level is full, an electric control valve of an overflow pipe is opened to conduct overflowing and the discharge pump is opened to conduct material suction at the same time. The mercerized weak waste alkali recycling and utilizing device is simple and easy to operate, alkali liquid can be transferred and transited effectively, the device is used in cooperation with operation of another process, no manual operation is needed, production efficiency is improved, and the device is applicable to production.

Description

technical field [0001] The invention relates to the field of recycling waste light alkali, in particular to a recycling device for mercerizing waste light alkali. Background technique [0002] Mercerizing is a processing process that can essentially change the properties of knitted fabrics. It usually refers to cotton fabrics (cotton yarn, cotton cloth) being treated with a concentrated caustic soda solution under tension to obtain silk-like luster and improve dyeing uniformity and Color yield, retain higher tensile strength properties after washing and wearable finishing, obtain better dimensional stability, and have different degrees of changes in physical and mechanical properties such as strength, elongation and elasticity. According to the needs of production development and the principle of sustainable development, the waste caustic soda used for mercerizing needs to be recycled and reused. The workshops in this factory area are far apart. The spent caustic soda used f...

Problems solved by technology

According to the needs of production development and the principle of sustainable development, the waste caustic soda used for mercerizing needs to be recycled and reused. The workshops in this factory area are far apart. The spent caustic soda used for mercerizing needs to be recycled first and then processed for use in other processes. However, the current Recycling devices cannot meet the needs of production, so it is very necessary to solve the above problems
