Problems solved by technology

When rainwater washes the road surface, it will take away the grease on the road surface; in addition, the existing rainwater treatment device cannot solve the turbulent flow of rainwater entering the system well, and the treatment of filtered impurities and sludge is also relatively complicated, and it cannot Rainwater contains a small amount of phosphate and nitrogen for effective absorption, causing certain damage to the environment

Embodiment 1

[0026] An initial rainwater cyclone type solid-liquid separation facility, including a housing 9, a filter housing 6 is vertically arranged in the housing 9, and the water inlet 1 of the housing and the water inlet 2 of the filter housing pass through a pipeline connection, the upper side wall of the filter housing 6 is closed, the lower side wall is provided with a filter hole 7, a water outlet is provided on the housing 9, and an oil baffle covering the water outlet 3 is provided at the water outlet 3 5. The oil baffle 5 is a baffle through which rainwater can pass, and the sundries (sludge, plastic bags, leaves, etc.) Grease is used to block, ensuring the cleanness of rainwater entering the municipal pipeline.

[0027] The water inlet 1 and the water inlet 2 of the filter housing are on the same spiral line, which prolongs the journey of rainwater in the filter housing 6, and can continue to work even when the water volume is large; the filter housing The body 6 and the ho...

Embodiment 2

[0030] The water inlet of the housing 9 is obliquely arranged at the middle and upper part of the housing 9 .

Embodiment 3

[0032] The bottom of the filter housing 6 can rotate relative to the housing 9 at a set angle, which can help prolong the travel of rainwater in the filter housing 6 and alleviate turbulent flow.

[0033] The filter housing 6 is connected to the bottom of the housing 9 through a rotating shaft, and the water inlet 1 of the housing 9 is connected to the water inlet 2 of the filter housing through a telescopic pipeline.

Abstract

The invention discloses a swirl-flow-type solid-liquid separation device for initial rainwater, which includes a shell body. A filter shell body is vertically disposed in the shell body. A water inlet of the shell body is communicated with the water inlet of the filter shell body. An upper side wall of the filter shell body is sealed. Filtering holes are formed on a lower side wall of the filter shell body. A water outlet is formed in the shell body. An oil baffle is arranged at the water outlet. The water inlet and the water inlet of the filter shell body are disposed in the same spiral line. By means of arrangement of the oil baffle at the water outlet of the shell body, grease or oil films in rain water can be removed effectively, thereby avoiding damage on river environment. The whole purifying system effectively prolongs the distance of rainwater in the filter shell body and alleviates turbulence. Foreign matters can be filtered away by means of the lower side wall of the filter shell body simply and conveniently. The filter shell body is disposed in the shell body in an eccentric manner and the water inlet of the shell body and the water inlet of the filter shell body are disposed in the same spiral line, so that turbulence status of rainwater in the system is further alleviated.

Description

technical field [0001] The invention relates to rainwater purification, in particular to an initial rainwater cyclone solid-liquid separation facility. Background technique [0002] Rainwater is an important link in the natural water cycle system, and plays a key role in regulating and replenishing regional water resources and improving and protecting the ecological environment. Since the initial rain washed away various pollutants on the surface, the pollution level is high and the impact load is large, so it is suitable for purification treatment. The initial rainwater includes undissolved suspended pollutants (including oil film and oil droplets), dissolved and colloidal pollutants, and finely suspended organic pollutants, which mainly come from the oil pollution produced by cars in daily life, especially When the engine runs at high speed, the partially dispersed engine oil is discharged together with the exhaust gas. Older engines drip oil badly, and on the other hand...
