Problems solved by technology

[0002] The grit effect of the traditional advection grit chamber is greatly affected by the fluctuation of influent water and sand content. At the same time, the content of organic matter in the grit is high, and special sand washing treatment is required; the aerated grit chamber is formed by aeration The swirling flow of water increases the chance of collision and friction between sand particles, the sand removal efficiency and the separation effect of sand organic matter are better, and it has good impact resistance. The establishment of anoxic environment has adverse effects. In addition, the aeration device is added, and the equipment cost is high, which increases the difficulty of operation and maintenance.

Embodiment Construction

[0030] The patent of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 Shown is a hydrocyclone diffusion device for a grit chamber, mainly including a hydrocyclone pump 1 and a hydrocyclone diffusion pipe 2 . The hydrocyclone pump 1 is installed at the water outlet of the grit chamber, presses the sewage into the hydraulic diffusion pipe 2 according to a certain flow rate, and a number of jet nozzles 3 are installed on the diffusion pipe 2 according to a certain interval, and the sewage in the diffusion pipe flows from the The jet nozzle 3 sprays out to form a vertical swirl, and superimposed with the horizontal flow along the length direction of the pool to form a helical flow (such as figure 2 shown), so as to achieve the purpose of efficiently separating sand particles.

[0032] The hydraulic diffusion pipe 2 is fixed on the bottom side of the pool through the ...

Abstract

The invention discloses a method for installing and using a hydrocyclone diffusing device for a grit chamber. The method comprises the steps: selecting multiple sections of diffusing pipes of different pipe diameters, arranging the diffusing pipes of different pipe diameters according to the size, fixing the arranged diffusing pipes on one side of the bottom of the grit chamber through a pipe rackbearing, installing a hydrocyclone pump at the end at which the hydraulic diffusing pipe with a largest pipe diameter is arranged, starting the hydrocyclone pump, pressing sewage into the hydraulic diffusing pipes, spraying out the sewage from nozzles of the hydraulic diffusing pipes so as to form vertical cyclone flow, and superimposing the cyclone flow on horizontal flow along the length of a pool to form spiral flow so as to achieve the purpose of separation of grit. The purpose of pipe material saving is achieved through variable diameters of the hydraulic diffusing pipes, and the cycloneflow effect is improved by optimizing the opening direction of a jet nozzle.

Description

technical field [0001] The patent of the present invention relates to the technical field of sewage treatment and environmental protection, specifically a method for installing and using a hydrocyclone diffusion device used in a grit chamber.
