Full-automatic mining wastewater filter and operation method thereof

Abstract

The invention relates to a full-automatic mining wastewater filter and an operation method thereof. The full-automatic mining wastewater filter is characterized by comprising two single filter units and an electric control system, each of the two single filter units is provided with a water inlet connecting tube and a water outlet connecting tube, the two water inlet connecting tubes are parallelly connected with a total water inlet tube, the total water inlet tube is provided with a water inlet, the two water outlet connecting tubes are parallelly connected with a total water outlet tube, the total water outlet tube is provided with a water outlet, an electric butterfly valve is arranged between each water inlet connecting tube and the water inlet, two blow-off openings are respectively arranged on tube walls of the two water inlet connecting tubes and are respectively provided with an electric blow-off valve, and the two electric butterfly valves and the two electric blow-off valvesare electrically connected with the electric control system. The full-automatic mining wastewater filter can realize full-automatic filtering by the aid of the electric control system, branches of the two single filter units can work alternately, filtering efficiency is high, mining wastewater enters the single filter units from bottom to top, filtering effect is good, and accordingly the full-automatic mining wastewater filter and the operation method thereof can be widely applied to online filtering treatment processes of mining wastewater such as mine water and the like.

Description

technical field [0001] The invention relates to a waste water filtering device and its operating method, in particular to a fully automatic mining waste water filter and its operating method. Background technique [0002] As a new energy-saving technology, heat pump technology is being more and more widely used in coal mine heating and air conditioning fields. This technology mainly uses the heat pump unit to extract the low-temperature heat energy of the unique low-temperature waste heat resources of coal mines, such as mine return air, mine drainage, pit mouth power plant cooling water, bathing wastewater, etc., to meet the needs of building heating, air conditioning, shaft antifreeze and hot water for bathing in coal mine industrial squares. , replacing the two systems of traditional boiler and split air conditioner, which has significant energy-saving and economic benefits. [0003] The following problems exist in mine drainage, bathing wastewater, and return air heat e...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in mine drainage, bathing wastewater, and return air heat exchange circulating water after treatment by mine return air heat exchangers, which are used to provide low-temperature heat sources for heat pump units: mine drainage dissolves many minerals in the process of flowing underground At the same time, it also contains a certain amount of coal dust, quicksand and other impurities; bathing wastewater contains a large amount of human skin secretions, hair, coal slime, dirt, synthetic detergents, etc., and often contains pathogenic bacteria, viruses and parasite eggs, as well as inorganic salts Chlorides, sulfates, phosphates, bicarbonates, and impurities such as sodium, potassium, calcium, and magnesium; the return air heat exchange circulating water treated by the mine return air heat exchanger absorbs the return air in the heat exchange process Impurities such as coal dust; therefore, impurities such as suspended particles in the above-mentioned water quality will cause wear and tear on equipment such as water pumps, and other impurities will also have an adverse effect on the pipelines of heat pump units. After treatment, it can be used as a low-temperature heat source for heat pump units
