Anti-blocking device of sewage cyclone

Abstract

Belonging to the technical field of blockage prevention of sewage cyclones, the invention discloses an anti-blocking device of a sewage cyclone. The anti-blocking device comprises a box body with an open top, and an inlet and an outlet that are respectively disposed at the front end and rear end of the box body, the outlet is connected to the sewage cyclone, the box body is internally equipped with a filter screen unit comprising a plurality of filter screens, two sides of the box body are respectively equipped with an auxiliary filter unit communicated with the box body, water inlets of the auxiliary filter units are communicated with the front side of the filter screen unit, and water outlets of the auxiliary filter units are communicated with the rear side of the filter screen unit; impurity discharge ports of the auxiliary filter units are communicated with impurity treatment boxes; and a filter screen at the most front end in the filter screen unit has guide parts adjacent to thewater inlets of the auxiliary filter units at both ends close to the side wall of the box body. The anti-blocking device provided by the invention can perform auxiliary filtration while filtering wastewater in the box body through the filter screens, reduces the filtration pressure of the first filter screen, and effectively reduces the occurrence rate of blockage.

Description

technical field [0001] The invention relates to the technical field of anti-clogging of a sewage cyclone, in particular to an anti-clogging device of a sewage cyclone. Background technique [0002] In wet desulfurization, the waste water cyclone belongs to the final cyclone equipment of the waste water system, and the foreign matter in the system has to pass through this equipment, such as the rubber liner that wears off the rubber lined pipe, the scales that fall off the absorption tower, and the liner worn by the mill. , wood chips carried by limestone, etc. The diameter of the sedimentation nozzle at the bottom of the wastewater cyclone is generally 6 to 10mm. These foreign objects will cause blockage when passing through the wastewater cyclone, which will stop the operation of the wastewater system and affect the safe and stable operation of the system. The existing solution is to install a Y-shaped filter between the outlet of the gypsum cyclone and the inlet of the se...

Problems solved by technology

The disadvantages are: 1. Due to the use of a fully enclosed Y-type filter, it is not easy to be found after clogging, and it is easy to cause the slurry overflow of the gypsum cyclone; 2. Because the structure of the storage tank is not reasonable enough, it is not easy to be cleaned. It takes a long time to unclog the type filter after clogging, and it is necessary to stop the operation of the wastewater system when unclogging, which affects continuous operation

[0004] The anti-clogging device of this patent is to filter the waste water in the tank when it enters the waste water cyclone through multiple filter screens, so that the impurities and garbage entering the waste water cyclone are less, but the first filter screen is often used when filtering. After being subjected to a large water pressure, the probability of clogging is relatively high, and because the filter needs to be treated after the sewage in it is discharged or the filter is removed, the treatment process is longer , The treatment efficiency is low, and it will affect the progress of sewage treatment, which is not conducive to cleaning the filtered impurities, and cannot be better used with a treatment system with a large processing capacity, which is practical and inconvenient
