Description

Silencing device for mine water advanced treatment system

Technical Field

The utility model belongs to the technical field of colliery water treatment facilities technique and specifically relates to a silencing device for mine water deep treatment system is related to.

Background

The mine water of the coal mine refers to all water permeating into an underground mining space in the coal mining process, the discharge of the mine water is one of pollution sources with industrial characteristics in the coal industry, the quantity is large, the water inflow amount of the coal mine in China every year is 20 to billion cubic meters, and the characteristics of the mine water depend on the geological environment of coal formation and the mineral chemical composition of coal strata. When mine water flows through a coal face and a roadway, coal rock powder and some organic matters enter the water due to the influence of artificial activities, and the mine water in China generally contains suspended matters mainly comprising the coal rock powder and soluble inorganic salts, has few organic pollutants and generally does not contain toxic substances. Therefore, the mine water is purified and utilized, and great economic and social benefits are generated.

At present, the technology for treating suspended matter mine water is mature, and effluent can reach the standard of industrial water only by adopting the conventional processes of coagulation, precipitation and filtration. Coagulation is carried out by adding coagulant into waste water to make colloidal particle matter generate coagulation and flocculation to form larger particle or flocculating constituent, and then separating suspended particle from water to purify waste water. Coagulants can be classified into inorganic salts and high molecular substances 2. The factors influencing the coagulation effect are as follows: water temperature, pH value, turbidity, hardness, coagulant adding amount, etc. After the coagulation reaction, the mine water is treated by a sedimentation tank to remove large-particle suspended matters, so that solid-liquid separation is realized. The sedimentation tank can be divided into an advection type, a vertical flow type and a radial flow type according to the water flow direction in the tank. The precipitated mine water is filtered by arranging a particle material layer, the filter material is generally anthracite and quartz sand, the common filter facilities are a fast filter tank and a gravity type valveless filter tank, and the filtered mine water can reach the industrial water standard. If the treated mine water is used as domestic water, an adsorption process is required to be added after coagulation, precipitation and filtration treatment to remove organic pollution in the water.

The newly developed advanced water treatment technology is to treat water directly from mine water to water which can be drunk directly by people, the adopted process is usually a membrane purification technology, and the process flow is to pump the mine water into a pre-settling regulating reservoir and then convey the water in the pre-settling regulating reservoir to a membrane processor by a water pump for treatment to obtain the drinking water which can be used directly by people.

The core equipment of the advanced water treatment system is inorganic ceramic membrane tube filtering equipment, the inorganic ceramic membrane is an asymmetric membrane which is prepared by inorganic ceramic materials through a special process, the asymmetric membrane is tubular or multi-channel, micropores are densely distributed on the tube wall, under the action of pressure, mine water flows in the membrane tube or outside the membrane, water molecules penetrate through the membrane, and macromolecular substances (or solid particles and liquid droplets) are intercepted by the membrane, so that the aim of purifying sewage is fulfilled.

Because the mine water contains a large amount of suspended matters and substances containing oil, micropores on the surface of the inorganic ceramic membrane tube can be blocked and the membrane flux is reduced in a short time, so that the service life of the inorganic ceramic membrane tube is shortened, the inorganic ceramic membrane device cannot normally run to achieve the expected effect, and a large amount of manpower and financial resources are wasted.

The prior art, for example, chinese patent publication No. CN201735342U, discloses a backwashing device of mine water film purification machinery, which is composed of a backwashing air pipeline, an exhaust air pipeline, a drainage pipeline, an electric control valve, and a water storage tank. The method is characterized in that: the water storage tank is respectively connected with the back-flushing pipeline, the exhaust pipeline and the drainage pipeline; the back flushing gas pipeline, the exhaust pipeline and the drainage pipeline are respectively provided with an electric control valve, firstly, purified water is supplemented to the water storage tank, water in the high-pressure gas compression water storage tank is used for carrying out high-pressure water back flushing on the membrane purification system, the whole process needs 10-30 seconds, and the back flushing is carried out once every 20-30 minutes.

Because the mine water is in the advanced treatment process, the anti-cleaning device of the online cleaning system is used for discharging redundant high-pressure gas after the membrane tube in the membrane equipment is cleaned online for one time, the high-pressure gas is released instantly and carries some water vapor, the high-pressure gas expands at a high speed in the releasing process to generate huge noise like blasting sound, the noise can exceed 126 decibels after being measured to form noise pollution, accurate time is not provided during the high-pressure gas discharging process, no early warning is provided, nearby workers can be scared, and tinnitus can be generated when the workers near the high-pressure gas are serious.
