Embodiment Construction

[0016] The present invention will be further described below in conjunction with the embodiments and with reference to the accompanying drawings. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the direction in the figure, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0017] As shown in the figure, the present invention provides a coal chemical wastewater pretreatment device, including a waste water pool 1 and a degreasing pool 2; the waste water pool 1 and the degreasing pool 2 are connected through a water inlet pipe 3 at the bottom. The water inlet pipe 3 is provided with a plurality of heating rings 4, the heating rings 4 are c...

Abstract

The invention discloses a coal chemical wastewater pretreatment device, which comprises a wastewater pool and an oil removal pool, wherein the wastewater pool and the oil removal pool are communicatedthrough a water inlet pipe at the bottom; a plurality of heating rings are arranged on the water inlet pipe; the heating rings are tightly attached to the outer surface of the water inlet pipe; a first guide wheel, a second guide wheel, a third guide wheel and a fourth guide wheel are respectively arranged in the upper end wall and the inner wall of the oil removal pool; a filtering screen is ofa cuboid structure; the end part of a water outlet is contained in the filtering screen; the lower end of a water filtering box is provided with a connecting water pipe. In the wastewater flowing process, heating treatment is performed; the density of oil type substances is greatly reduced, so that the oil type substances float; the oil type substances are sucked by oil sucking cotton and are thenextruded into an oil collecting barrel; next, through the filtering screen in the water filtering box, it is further ensured that the oil type substances are totally cleared away. The coal chemicalwastewater pretreatment device has the advantages that the structure is simple; the operation is stable; the oil removal effect is good; the smooth proceeding of the subsequent wastewater treatment isensured.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a coal chemical wastewater pretreatment device. Background technique [0002] Coal chemical industry is a comprehensive industrial process in which mined coal is used as raw material and transformed into various fuels and chemicals through a series of chemical and chemical processes. The product materialism produced by it is divided into coal coking, coal gasification, and coal gasification to synthesize other products and direct liquefaction. Coal chemical industry wastewater is mainly produced by high-temperature cracking of coal, and some wastewater will also be produced in the process of gas purification and recovery of chemical products. [0003] At present, the treatment process of coal chemical wastewater at home and abroad is mainly composed of physicochemical and biochemical processes. Due to the presence of oily substances in the wastewater treatment proc...
