Description

TECHNICAL FIELD

[0001] The utility model relates to waste water treatment equipment technical field, concretely is a kind of filter device for semi-coke production wastewater. BACKGROUND

[0002] Semi-coke, also known as semi-coke, is a new type of carbon material made of high-quality fine coal. The production process of semi-coke mainly includes coal preparation, carbonization, screening and transportation and coal gas purification units. In the coal preparation stage, raw coal is crushed and screened, with a particle size of about 0-80mm, and is sent to the coal storage bin above the dry distillation furnace through the coal belt. In the carbonization stage, the raw coal gradually descends in the dry distillation furnace, passes through the drying section, the dry distillation section and the cooling section, and finally carbonizes into semi-coke. In the screening and transportation stage, semi-coke is screened to form products of different particle sizes. The coal gas purification unit processes the raw coal gas generated during carbonization to separate by-products such as tar. The entire production process uses advanced dry distillation and blending technology to ensure stable quality of semi-coke.

[0003] Semi-coke production wastewater contains a large amount of suspended solids, organic matter and other pollutants. If it is not properly treated and directly discharged, it will cause serious pollution to the environment. Therefore, the filter device plays a crucial role in the treatment of semi-coke production wastewater. Through filtration, solid particles and impurities in wastewater can be effectively removed, reducing COD and BOD values, thereby reducing pollution to water bodies. However, the filter devices currently used can only perform primary filtration, with limited treatment effect, which cannot meet the increasingly stringent environmental protection standards. Primary filtration can only remove larger particles, but the removal effect of fine particles and dissolved pollutants is insufficient, resulting in a high concentration of pollutants after wastewater treatment, which cannot meet the discharge requirements. In addition, the existing filter device has certain difficulties in installation and disassembly, making maintenance and cleaning cumbersome. This complex operation process reduces the filtration efficiency, increases the operating cost, and also prolongs the downtime of the equipment, affecting the overall efficiency of the production line.
