Hydraulic Particle Separator

Abstract

The invention discloses a waterpower particle separating device which comprises a well body, a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are arranged at the front and rear ends of the well body. The waterpower particle separating device is characterized in that the device further comprises a rotational flow cylinder, a dross retaining wall and a flow limiting wall which are sequentially arranged in the well body from front to back; the rotational flow cylinder is an unclosed cylinder body formed by rolling a steel plate, wherein an opening is formed in the axial direction of the unclosed cylinder body; the axial direction of the rotational flow cylinder is the vertical direction, the lower end of the rotational flow cylinder is connected with the bottom of the well body, and an opening of the water inlet pipe corresponds to the opening of the rotational flow cylinder; the top of the well body extends downwards to form the dross retaining wall, and the bottom of the well body extends upwards to form the flow limiting wall. The waterpower particle separating device is simple in structure and convenient to use; by means of the mode of combining waterpower rotational flow separating, floating object intercepting and natural settling, floating objects in rainwater and particles are treated, the removal rate of the device can reach 90%, the intercepted minimum particle can reach 50 micrometers, and the device is suitable for pretreatment before the rainwater enters a city main pipe or pretreatment before a rainwater pipeline drains natural water.

Description

technical field [0001] The invention relates to the technical field of rainwater pretreatment, in particular to a hydraulic particle separation device. Background technique [0002] With the rapid development of urbanization, non-point source pollution caused by rainwater runoff has gradually become an important source of urban water pollutants. Pollutants in urban stormwater runoff mainly come from wet deposition caused by precipitation leaching atmospheric pollutants and leaching of urban impervious surface pollutants, and the latter accounts for more than 90% of the total amount of pollutants in stormwater runoff. Particulate matter is the main carrier of urban impermeable surface pollutants, such as: atmospheric deposition, vehicle exhaust, tire wear, snow melting agent, sediment on construction sites, solid waste and leachate and other particulate matter contain a large number of pollutants (COD, nutrients , organic matter, heavy metals, pathogens, etc.), will eventual...

Problems solved by technology

[0004] Therefore, when the rain falls to the ground and forms runoff, it will contain a large amount of particles such as sediment and floating objects. If the particles and floating objects in the rainwater are not intercepted and discharged directly to the natural water body, the natural water body will be polluted. Most of the rainwater is treated by filter screen, and the rainwater is pre-treated by simple filtration, but this filter filter method will bring many problems: 1. The filter screen may be blocked, hindering the discharge of rainwater and causing urban waterlogging

2. Floating objects are not collected after being intercepted, so cleaning is very inconvenient
