Integrated oil and turbidity removing device

Abstract

The invention discloses an integrated oil and turbidity removing device which comprises a device body; a clarification zone is arranged at the upper part of the device body, and a mud settling zone isarranged at the lower part; symmetrical mud collecting hoppers are arranged under the mud settling zone; a flocculation reaction chamber is divided into a first flocculation reaction chamber and a second flocculation reaction chamber; the first flocculation reaction chamber is embedded in the second flocculation reaction chamber and is communicated with the second flocculation reaction chamber through the open lower end of the first flocculation reaction chamber; a slag collecting hopper is connected under the second flocculation reaction chamber; a water outlet is formed above the second flocculation reaction chamber and is close to the symmetrical mud collecting hoppers; the symmetrical mud collecting hoppers comprise two symmetrical mud hopper cone plates; an included angle between each of the mud hopper cone plates and a horizontal plane is 45 degrees; a roof structure with an included angle of 90 degrees is formed between the two mud hopper cone plates. The integrated oil and turbidity removing device disclosed by the invention has the benefits that all the functions of a chemical oil remover and a high-speed filter are combined, and the floor area is reduced.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an integrated oil and turbidity removal device. Background technique [0002] The continuous casting or hot rolling turbid circulating water in the iron and steel industry contains iron oxide scale and oil. The original treatment process adopts "chemical degreaser + high-speed filter". The outlet water overflows to the hot water pool, and then is pressurized by the lift pump to the high-speed filter for further oil and turbidity removal treatment. The outlet water of the high-speed filter directly enters the cooling tower for cooling. use. The high-speed filter needs to be backwashed regularly, and an additional backwash pump is required for backwashing. [0003] The above treatment process equipment occupies a large area, high investment and operation costs, cumbersome operation, difficult to control water quality and sludge discharge.
