Description
Technical field
The utility model relates to a kind of short flow process drainage of coal pits waste heat recovery comprehensive utilization treatment system, belongs to drainage of coal pits heat recovery field.
Background technology
Drainage of coal pits refers in progress of coal mining, each subsurface geology gushes to seep water to gush and is seeped into the natural underground water being discharged from tunnel, what the watering in down-hole coal excavation production process in addition,, depositing dust, fire extinguishing grouting, fire-fighting and hydraulic efficiency installation produced is also a part for pit water containing coal dust waste water.Therefore it had both had Characteristics of Groundwater, but be subject to artifact pollution, the characteristic of pit water depends on the geologic media of coal-forming and the mineral chemical composition of coal measure strata, and wherein water temperature geologic condition and water-filling factor have decisive influence for water quality, the water yield of pit mining process waste water of mine.In drainage of coal pits, contain the suspended substance that quantity does not wait, a small amount of organism and mushroom, wherein the main component of suspended substance is coal dust, coal dust content is up to 1000 ~ 4000mg/L.Pit water water temperature remains on 16 DEG C ~ 25 DEG C throughout the year, has very high recovery of heat to be worth.
Traditional drainage of coal pits waste heat recovery processing system is that drainage of coal pits is imported to preliminary sedimentation tank after coagulating sedimentation, supernatant water layer is imported settling pond by preliminary sedimentation tank lift pump, then enter raw water tank, import medium filter through raw water pump, after filter-sterilized, after water resource heat pump extracts mine water residual heat, discharge on the spot or sweep for place, whole recycling system is: drainage of coal pits → preliminary sedimentation tank → preliminary sedimentation tank lift pump → settling pond → raw water tank → raw water pump → medium filter → water resource heat pump (extraction mine water residual heat) → discharge on the spot or sweep for place.Traditional recovery and processing system technical process is long, equipment progression is many, quantity is many, pit water water temperature loss large (water temperature is lost approximately 5 DEG C ~ 10 DEG C) causes water resource heat pump initial cost larger, and plant area takes up an area huge, invest highly, can not meet coal mining enterprise's construction requirements of " the friendly type of resource, environment saving type "; On the other hand, the operation of settling pond is subject to water load variations and changes, and effluent quality is unstable, and level of automation is low, has a strong impact on the effluent quality of follow-up equipment.Therefore, the final outflow water of system is often directly discharged, and causes a large amount of water resource waste.
Utility model content
For deficiency of the prior art, the utility model proposes that a kind of technical process is short, equipment progression is few, quantity is few, plant area takes up an area coal mine heat recovery total system less, that investment is saved, comprehensive utilization degree is high.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of short flow process drainage of coal pits waste heat recovery comprehensive utilization treatment system, it comprises preliminary sedimentation tank, self-cleaning filter, tubular type micro-filtration and water source heat pump units; In preliminary sedimentation tank, establish preliminary sedimentation tank lift pump, preliminary sedimentation tank lift pump is transported to self-cleaning filter by the drainage of coal pits in preliminary sedimentation tank through pipeline, the water side of self-cleaning filter is communicated with the feed-water end of tubular type micro-filtration, and the water outlet of tubular type micro-filtration is communicated with water source heat pump units.
On pipeline between preliminary sedimentation tank and self-cleaning filter, establishing flocculation agent stores and throws pressure device and sterilant storage and throw pressure device.
In addition, self-cleaning filter and tubular type micro-filtration are established backwash drainage pipeline, and backwash drainage pipeline is communicated with preliminary sedimentation tank.
Self-cleaning filter is 304 stainless steel aperture strainers, and filtering accuracy is 500 μ m.
The long 3800mm of tubular type micro-filtration, putamina diameter 150mm, the long 3000mm of putamina, water inlet suspension content is less than 1000mg/L.The tubular membrane element of tubular type micro-filtration inside is ultrahigh molecular weight polypropylene (PP) material, and film internal diameter is 5.5mm, and membrane pore size is 0.2 μ m.
Compared with the single drainage of coal pits waste heat recovery of tradition water treatment system, the utility model has been cancelled settling pond, raw water tank, raw water pump and medium filter in technical process, them are replaced with self-cleaning filter and tubular type micro-filtration, reduce equipment sum of series quantity, reduce the energy consumption of nearly half, subtract the floor space being a half, this has saved the energy in reducing laid down cost.In addition, through the utility model system pit water after treatment, before and after going out ground, calorific loss is less, temperature difference 1oC ~ 5 oC, this has greatly improved the heating efficiency of water source heat pump units, and the pit water after heat exchange, without processing and can be directly used in life and production use again, has improved operational efficiency and has reduced running cost.
