A rapid settling device for industrial circulating water

Abstract

The invention discloses a rapid settling device for industrial circulating water, which includes a settling combination, a negative pressure fan combination, a temporary storage tank for circulating water and a control box. and an air supply plate, the settling frame combination is composed of a supporting platform plate and a settling tank, a welding hole is opened on the top side wall of the supporting platform plate, and one end of the settling tank passes through the welding hole and is welded on the supporting platform plate . The settling combination of the present invention adopts a closed structure, and a needle-slit dense tube device is set inside, and the needle-slit circulation device on the needle-slit dense tube device can discharge the water from the lower part of the settling tank through the delivery pipe and fall to the circulating water surface in the settling tank , to realize the up and down flow of water, and the large particles (calcification, oxides and quicksand particles, etc.) in the circulating water will accelerate into the confluence cover of the needle seam circulation device at the bottom, thus realizing the rapid settlement function of large particles of magazines.

Description

technical field [0001] The invention relates to the technical field of industrial sewage treatment, in particular to a rapid settling device for industrial circulating water. Background technique [0002] Because industrial circulating water contains a large amount of calcification, oxides, quicksand, dust, microbial bacteria and corrosive ions, these harmful substances usually cause harm to pipelines and equipment, so circulating water is usually purified by a purification treatment system before recycling In use, the current circulating water treatment system usually uses a filter membrane for purification, but there are still shortcomings in this method: 1. The circulating water contains a large amount of large particles, and the purification process uses the circulating water to filter and purify as a whole, which will reduce the purification efficiency; 2. Due to the existence of large particles of impurities, the filter membrane used for purification is easily blocked,...

[0002] Because industrial circulating water contains a large amount of calcification, oxides, quicksand, dust, microbial bacteria and corrosive ions, these harmful substances usually cause harm to pipelines and equipment, so circulating water is usually purified by a purification treatment system before recycling In use, the current circulating water treatment system usually uses a filter membrane for purification, but there are still shortcomings in this method: 1. The circulating water contains a large amount of large particles, and the purification process uses the circulating water to filter and purify as a whole, which will reduce the purification efficiency; 2. Due to the existence of large particles of impurities, the filter membrane used for purification is easily blocked, thereby reducing the service life of the purification membrane; 3. The circulating water contains a lot of heat, which needs to be reused after heat exchange, and the current heat exchange usually uses surface The air cooling method is used for cooling, and the cooling speed is slow. In order to reduce the work burden of the purifier, the present invention provides a rapid settling device for industrial circulating water
