Description

Technical Field

[0001] The invention relates to a wastewater filtering device and method for a thermal power plant. Technical Background

[0002] Thermal power plants are not only large users of water and drainage, but also large polluters. In addition to being an energy carrier, water also generates wastewater in many processes within thermal power plants. The amount of wastewater discharged is large, thus causing pollution and damage to the environment.

[0003] There are many heavy oil facilities in thermal power plants and coal-fired power plants that may discharge oily wastewater. These oils include heavy oil, lubricating oil, insulating oil, kerosene and gasoline. At present, the main problem of oily wastewater is that the oil content and phenol content in the water exceed the standard. When excessive oily wastewater is discharged into natural water bodies, a part of the light oil will form an oil film on the water surface, destroying the natural gas explosion conditions of the natural water body, and the heavy oil will sink to the bottom of the water body, thereby affecting the normal activities of the aquatic animal and plant groups, causing serious pollution to the environment, and more seriously may cause ecological damage. Summary of the invention

[0004] The purpose of the invention is to solve the problem of oily wastewater polluting the environment, and to provide a wastewater filtering device and method for a thermal power plant.

[0006] Filters are movably installed in the water inlet pipe and the water outlet pipe through buckles, and a handle is fixedly installed on the filter.

[0007] A thermal power plant wastewater filtering device and method, the first filtering mechanism comprises a rotating shaft and a motor A, one end of the rotating shaft is electrically connected to the motor A and is fixed to the top of a conical barrel; a plurality of slots are arranged on the surface of the rotating shaft, a stirring rod is movably installed in the slot, and a filtering sponge is movably installed on the surface of the stirring rod.

[0008] A thermal power plant wastewater filtering device and method, the second filtering mechanism comprises a filter element, the filter element is movably installed inside a filter box, the filter element contains sawdust and clay, the sawdust and clay can absorb oil, and can achieve the effect of wastewater purification. Beneficial Effects

[0009] 1. The present invention filters the oily wastewater through the first filtering mechanism and the second filtering mechanism, so that the oily wastewater reaches the discharge standard after being treated, thereby protecting the environment.

[0010] 2. The filter element of the present invention is made of sawdust and clay, which is low in price and can be replaced by opening the end cover. The replaced sawdust and clay can be reused to achieve sustainable utilization.

[0011] 3. The present invention has a simple structure and is easy to install or maintain, which reduces the labor of the crew and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
