2results about How to "Implement preliminary processing" patented technology

This utility model relates to the field of wastewater treatment technology, and more particularly to a wastewater treatment device for river pollution sources. It includes a filter chamber, a filter screen, spiral blades, a slag discharge port, a drive motor, an installation chamber, an installation plate, an inspection door, a purification tank, and an aeration pipe. The filter chamber has a filter screen at its lower end and spiral blades at its upper end. A slag discharge port is located on the right side of the filter chamber, and a drive motor is located on the left side. An installation chamber is located on the outer side of the lower end of the filter chamber, with an installation plate at its upper end and an inspection door on its left side. A purification tank is located at the lower end of the installation chamber, and an aeration pipe is located on the inner side of the purification tank. This utility model removes larger impurities through the filter screen, achieving preliminary wastewater treatment and preventing the deposition of larger impurities in the purification tank. The drive motor controls the rotation of the spiral blades, pushing impurities on the filter screen surface towards the slag discharge port for convenient centralized collection and treatment.

The present application relates to atmospheric pollution equipment technical field, specifically, it relates to a kind of lubricating oil production waste gas treatment device, comprising: waste gas import connection pipe, flange, separator and purifier, the flange is installed in the end of the waste gas import connection pipe, the separator is communicated with the outlet of the waste gas import connection pipe, the purifier is connected with the separator, the waste gas import connection pipe is divided into two sections, spiral connection between two sections, the waste gas import connection pipe transports waste gas into the separator, the separator removes oil mist in waste gas, waste gas is recycled fine purification after entering the purifier, waste gas is thoroughly treated, ensure that volatile organic compounds and foul-smelling inorganic gas are treated clean, with the way of the lubricating oil production waste gas with complex characteristics is extremely strong targeted to carry out step-by-step depth comprehensive treatment, ensure long-term stable treatment effect to waste gas, to change clean gas exhaust into waste gas.
