Abstract
The utility model relates to a water purifier for water under coal mines, which is characterized in that a reacting barrel 4, clarifying conical body 5, a soil discharging barrel 6, a sludge conical body 3, a sloped pipe, a forced return water outlet pipe 11, filter material 13, an annular water collecting tank, a total water outlet tank 14, a back flushing pipe 12, etc. are arranged in a barrel body 1. After clarification and filtration, the turbidity of the yielded water of coal mine water in the water purifier can reach 3 DEG. The utility model has the advantages of high purifying efficiency, large treating ability, little investment, low running cost, convenient manufacture in factories, etc. and is mainly suitable for the treatment of water under coal mines, and the reclamation of mine water can be realized.
Description
Colliery mine water water purifier belongs to technical field of environmental science
" coal mine environment protection " 1991 the 3rd phases of periodical carry in national emphasis coal mine under the unified-allocation system pit water investigation seminar " opinion China's part emphasis coal mine water purification utilization present situation and the development countermeasure " literary composition and introduce; suspended substance removal all adopts ordinary method; its structures generally adopt dividing plate advection reaction tank; eddy current and Ying Chi; reactive multilayer pond tube settler, gravity valveless filter and siphon filter etc.Also have and adopt floor space few, collection coagulation, the circulatior clarifier that reacts, is deposited in one, mechanical accelerating purifying pool, to the pit water Processing Technology Research should carry out novel, efficient, the serial purifier of built-up type at present; Deng research.According to reporting for information about and investigating, be used for pit water and handled the collection coagulation again.Precipitate, filter in integral water purifier, it is less to have plenty of processing power, as opens Luan horse man ditch mine, only is 30m
3/ h; Have plenty of the circulatior clarifier of applying mechanically to water treatment and add filtering water purifier, its design variable is unreasonable, flocculating effect, and effluent quality is poor, and the actual treatment ability is about 1/2 of design, as the ore deposit, Guizhou; The actual water inlet concentration of suspension that has has added several large-scale settling tanks and has carried out pre-treatment, as the ore deposit, Guizhou below 500mg/l before water purifier.And general water purification residence time of water purifier is too short.
The purpose of this utility model is for improving coal mine environment, makes reclamation of mine water and efficient, novel, large-scale, combined type water purifying device are provided.
The utility model is at suspended particle fine size in the high concentration mine water, density is based on the little water quality characteristic of the sanitary sewage of silt particle, the water-purifying process process tangentially enters water purifier bottom reaction tube 1 for the pit water with dosing coagulant (polymerize aluminum chloride) and coagulant aids (polyacrylamide) solution after the external water pump of water purifier mixes, the current that (seeing Figure of description Fig. 1) generates alumen ustum through cyclone reaction eddy flow again rise to suspension settling section II further reaction and a solid-liquid separation, rise to tube settling district III and carry out the secondary solid-liquid separation by transition layer is stable through a current solid-liquid separation and that have the tiny alumen ustum of part, precipitated outlet water rises up into foam filter pearl filter material layer and mud enrichment region V on uniform through stabilizing layer supernatant liquor is back to filter by required head of filter bed and the pressure reduction of forcing effluent recycling pipe drag losses head and enters filtering layer top and distinguish IV after filtration and filter, and the perforation top board of filter back water by top band filter cloth enters annular collecting vat 14 and flow automatically to clean water basin again.The back flushing of filter material layer is drawn water by backwash pump and is pressed into the fixed backwash tube 12 in slit in the filter material layer, backwashing wastewater through row of conduits to the pit water equalizing tank.Clarification, precipitating sludge slip into the deslagging bucket automatically and enter mud enrichment region V along bucket bottom shore pipe, and thickened sludge drains into sludge sump through enrichment region bottom inside perforated sludge discharge pipe.
Be that the above-mentioned water purification technology scheme of clear foot needs, the utility model concentrates coagulation, clarification, precipitation, filtration, forced refluence outlet system, back-purge system, mud etc. and is combined as a cylindrical body.Its technical characterictic:
Water inlet concentration of suspension SS≤3000mg/l PH=7～8.5.
Delivery turbidity≤3 degree PH=7～8.5.
Diameter D=5.0m height overall H=8.2 5m processing capacity Q=100m
3/ h.
The utility model comes into operation more than a year and day organizes expert statement to think through Guizhou Province's coal-mining industry management board in one nine nine three year November 23～24 at Guizhou Na Luozhai mine mine water treatment station: 1; colliery mine water water purifier is with coagulation; clarification; tube settling; filter; mud concentrates and waits processing unit to be combined into one; it is reasonable to have technology; the purification efficiency height; processing power is big; take up an area of few; reduced investment; working cost is low; the operation tube just waits characteristics; mine water water quality meets the national environmental protection emission standard through the colliery of purifying treatment, reaches industrial multiplexing requirement.2, this water purifier adopts suspend clarification and Inclined-tube Settling Technology, is provided with the forced refluence rising pipe, and general water purifier is guaranteed the stable of slime layer that suspend, and keeps the body refuse balance, has improved the separating effect and the water-yielding capacity of suspension slime layer.3, operation shows through production practice over one year, this device research is successful, colliery mine water water purifier and treatment process system design are rationally advanced, handle the high concentration suspended matter pit water and can obtain significant social and economic benefit, reach the advanced level of domestic like product, have popularizing application prospect preferably.
Fig. 1 is a colliery mine water water purifier synoptic diagram.
Accompanying drawing drawing explanation: utility model for the ease of factory process making, field assembly, be designed to by cylindrical shell 1, base plate 2, mud cone 3, reaction tube 4, clarification cone 5, deslagging bucket 6, diagonal brace 7, inclined tube carrying cylinder 8, inclined tube carriage 9, inclined tube press frame 10, force effluent recycling pipe 11, less important component such as main parts size (seeing Figure of description) such as backwash tube 12, perforation top board 13, water leg 14 and pipe fitting, viewing window, access opening, helper form.Cylindrical shell 1 welding stands on the base plate 2.Mud cone 3 upper limbs and cylinder inboard wall welding, lower edge welds mutually with base plate 2.Reaction tube 4 is worn base plate 2 welding, and upper limb welds mutually with clarification cone 5 lower edges.Clarification cone 5 upper limbs and cylinder inboard wall welding.Deslagging bucket 6 by three shore pipes in bottom with the clarification cone 5 on pore weld mutually.Bucket top diagonal brace 7 and 8 welding of inclined tube carrying cylinder.Inclined tube carriage 9 centers and the welding of inclined tube carrying cylinder, carriage outer rim and barrel wall welding.Inclined tube presses the mode of connection of frame 10 identical with the inclined tube carriage.Forced refluence rising pipe 11 is worn cylindrical shell 1 welding.The person in charge of backwash tube 12 passes perforation top board central seal, and establishes support.Perforation top board 13 be upper and lower two-ply therebetween glass yarn screen cloth, circular slab and fan-shaped plate composition in the middle of plate is divided into, the lower plywood block welding on angle bracket, upper and lower laminate piece bolting.Annular collecting vat 14 is supported on the top board 13 with cushion block with total groove.
