Description
Technical field
The utility model belongs to stainless steel production unit field, is specifically related to a kind of acid-washing stainless steel system that reduces acid and water consumption.
Background technology
Rapid growth along with national economy; consumption presents a rapidly rising trend to stainless steel in China; make China's stainless steel industry also go from strength to strength and develop; stainless steel surface cleanup acid treatment technique also obtains development, has formed the technical process of sulfuric acid and nitration mixture comprehensive treating process, in acid cleaning process; because of the temperature of various acid solutions all higher; certainly will have various acid solution volatile matters and various waste gas and produce, be protection of the environment, need to carry out centralized collection again through processing up to standard after in the discharging atmosphere.At present, the pickling system in the stainless steel production technique, the utility model is called for short the acid-washing stainless steel system, comprises pickling tank, acid cycle tank, washing tower, acid mist treatment device; Pickling tank connects the acid cycle tank by acid line and forms the circulation loop, when the acid solution amount in pickling tank or concentration do not reach production requirement, in time by the acid cycle tank, supplement, according to practical situation, supplement a certain amount of water and acid in the acid cycle tank.The top of pickling tank connects the bottom of washing tower by acid mist pipeline, acid mist in pickling tank is transported to washing tower to be washed, make it meet the requirement of acid mist treatment device to reduce acid concentration, waste gas after washing enters atmosphere again after acid mist treatment device is processed, the spent acid after the washing tower washing is delivered directly to the waste water reclamation station and processes discharging; Spray water in washing tower can be recycled, and is transported to the waste water reclamation station after reaching finite concentration again.Setting as for pipeline, according to physical features, carry out reasonable Arrangement,, if need to be transported to the higher position of physical features by the liquid that physical features is lower, need to carry by pump is set, gas usually need to arrange blower fan and carry, and each pipeline all should arrange valve under normal conditions.Generally, the washing tower domestic demand will constantly be replaced new water and be absorbed the soluble material of part in acid mist to reach certain solubleness, thereby causes a large amount of acid waste water to discharge from washing tower, has increased the treatment capacity of acid-washing stainless steel system waste water.In recent years, according to the deployment of the Party Central Committee, State Council, along with policy, rules, the file of China's energy-saving and emission-reduction are progressively put into effect, the paces that China's propulsion energy-saving reduces discharging have been accelerated, therefore reduce enterprises of producing stainless steel ton steel water, reduce energy consumption, the problems such as minimizing discharge of wastewater seem very important.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of acid-washing stainless steel system that reduces acid and water consumption.
The technical scheme that its technical problem that solves the utility model adopts is: the acid-washing stainless steel system, comprise pickling tank, acid cycle tank and washing tower, the top of pickling tank connects the bottom of washing tower by acid mist pipeline, pickling tank connects the acid cycle tank by acid line and forms the circulation loop, and washing tower is by arranging valvular spent acid pipeline communication acid cycle tank.
Wherein, described valve is controlled by Controlling System.
Further, described Controlling System comprises controller and for detection of the proofing unit of acid solution liquid measure and acid content in acid cycle tank and washing tower, controller joint detection device, and described valve is controlled by controller.
The beneficial effects of the utility model are: the utility model is by being connected washing tower and valve being set with the acid cycle tank, can be when the acid cycle tank needs make up water and acid, by washing tower, the acid cycle tank is supplemented, by calculating, the water and the sour amount that obtain magnitude of recruitment and directly to the acid cycle tank, add, thereby meet the requirement that pickling tank is produced, save acid consumption and the water loss of pickling system.The utility model arranges Controlling System, Controlling System comprises controller and proofing unit, by the detection of proofing unit to acid solution liquid measure and acid content in acid cycle tank and washing tower, pass the signal to controller, thereby by-pass valve control is regulated the magnitude of recruitment of spent acid, reach the purpose of controlling the washing tower liquid amount balance, meet simultaneously the requirement that pickling tank is produced, pickling system is controlled simpler.
