Abstract

The invention relates to a device for efficient and clean treatment of coal washing water without chemicals, comprising a pretreatment tank, a clarification tank, a coarse filter, an ultrafilter, a sedimentation tank and a coal slime dehydrator; a baffle is arranged in the middle of the pretreatment tank, The coal washing water inlet pipe is arranged above the pool wall of the pretreatment tank, and the aeration inlet pipe is connected to the coal washing water inlet pipe along the vertical direction; the floating substance overflow pipe is arranged on the top of the pool wall of the pretreatment tank; Inclined tube sedimentation tank. The main feature of this invention is that it adopts a brand-new water treatment concept, and after carefully analyzing the characteristics of coal washing water, it proposes a chemical-free and efficient clean treatment process. The water treatment speed is dozens of times that of the traditional process, and the occupied area is less than 50% of the traditional process. It is especially suitable for the purification treatment equipment of coal washing water and mine water. Using the device of the present invention to treat coal washing water does not require adding any chemicals, which will inevitably help enterprises reduce operating costs, help enterprises meet environmental protection requirements, and truly realize zero sewage discharge.

Description

technical field [0001] The invention relates to the field of coal washing water separation and purification equipment, in particular to a device for efficiently cleaning coal washing water without chemicals. Background technique [0002] Coal is an important basic energy source in my country and has an important strategic position in economic and social development. However, the clean and efficient utilization of coal inevitably causes a large amount of water pollution, such as the coal washing water produced in the coal washing process. Therefore, it is imperative to invent an efficient and stable coal washing water treatment equipment. The coal washing water mainly contains suspended solids with a particle size of 20-50 μm. The main components of the waste water are fine coal powder, sand, clay, shale, etc. The coal washing water is particularly stable and will not settle naturally after standing for several months, so the treatment is very important. Difficulties. In the...
