Equipment for pretreating industrial water

Abstract

The invention relates to equipment for pretreating industrial water. The equipment comprises a flocculating agent blending tank, a flocculating sedimentation tank and a water reservoir, wherein the flocculating agent blending tank is connected with the flocculating sedimentation tank by a pipeline I; the water reservoir is connected with the flocculating sedimentation tank by a pipeline II; a flow sensor I is arranged at one port, which stretches into the flocculating sedimentation tank, of the pipeline II; and a flow sensor II is arranged at one port, which stretches into the flocculating sedimentation tank, of the pipeline I. The water inlet pipelines are provided with the sensors so that the adding amount of a flocculating agent is controlled; two feeding holes are formed in the flocculating agent blending tank so that two main components of a flocculating agent are blended according to the amounts and the flocculating agent added into the flocculating agent blending tank is adjusted, and the working amount of manual labor is saved; the sensors are used for working and are used for monitoring the adding amount of the flocculating agent so that the whole treatment work can be continuously operated; and furthermore, the waste caused by manual errors is reduced and the working period is prolonged, the production efficiency is improved and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of industrial water pretreatment, in particular to equipment for industrial water pretreatment. Background technique [0002] Industrial water usually includes process water, boiler water, washing water, and cooling water, but mainly boiler water and cooling water. The water quality requirements of boiler water vary according to the working pressure and temperature of the boiler. No matter what kind of boiler water is used, it has strict restrictions on the hardness of water. Anything that can cause corrosion, scaling and Most or all of the impurities such as dissolved oxygen, soluble silicon dioxide, iron and residual chlorine that cause the phenomenon of soda and water to poison the ion exchange resin should be removed. [0003] The average industrial cooling water consumption accounts for about 67% of the total industrial water consumption, among which the petroleum, chemical and steel industries are the...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide a coagulant for industrial water pretreatment in view of the deficiencies of the above-mentioned prior art. The water quality requirements have better solved the problems caused by the slow hydrolysis speed of the coagulant, many hydrolysis intermediate products, small floc particle density, and high content of metal ions in the effluent when conventional aluminum salts, iron salts and other coagulants are used in water treatment. The problem of poor coagulation effect
