Problems solved by technology

[0003] In order to solve the above problems, the invention patent application with application number 200810024478.2 discloses a coagulation tube reactor. This coagulation tube reactor only has the function of mixing sewage and medicine, and it also needs to be equipped with a solid-liquid separator as a Subsequent processing equipment increases equipment cost
And after the medicine is mixed with the sewage, the coagulation reaction produces large-particle solids. When using the above-mentioned coagulation tubular reactor, the large-particle solids tend to stay in the damping-enhanced coagulation structure and the joints or bends of the pipeline, causing pipeline blockage

Abstract

The invention discloses a tubular coagulation reaction device for sewage treatment. The device comprises a water inlet pipe, a chemical feeding pipe and a mixing pipe, wherein a precipitation desilter is connected to the mixing pipe; a pressure drum is arranged at the upper part of the chemical feeding pipe; a spoiler is arranged below the pressure drum; a chemical feeding port is formed in the pipe wall of the chemical feeding pipe between the spoiler and the pressure drum; a spiral flow guide plate is arranged on the inner wall of the upper end of the mixing pipe; the precipitation desilter comprises an inner barrel and an outer barrel; an overflow passage is formed between the bottoms of the inner and outer barrels; an annular baffle is connected between the inner and outer barrels, and is provided with multiple through holes; the upper surface of the baffle is covered by a filter layer above which a water outlet pipe is arranged; multiple dredge pipes are arranged at the bottom of the outer barrel; valves are arranged on the dredge pipes; silt collection tanks are mounted at outlets of the dredge pipes. According to the device, the precipitation desilter is simple in structure and low in construction cost; large particulate matters can be conveniently and effectively removed, the sewage treatment cost can be favorably reduced, and sewage can be continuously treated.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a tubular coagulation reaction device for sewage treatment. Background technique [0002] The existing sewage coagulation reaction device is a reaction tank. When in use, the sewage and medicines are passed into the reaction pool, stirred by a stirrer, so that the sewage and medicines are evenly mixed and reacted. This kind of reaction pool has a large volume, occupies a large area, has high requirements on the site, and has high implementation costs. [0003] In order to solve the above problems, the invention patent application with application number 200810024478.2 discloses a coagulation tube reactor. This coagulation tube reactor only has the function of mixing sewage and medicine, and it also needs to be equipped with a solid-liquid separator as a Subsequent processing equipment increases the equipment cost. And after the medicine is mixed with the sewage, the co...
