Description
Technical field
The present invention relates to water utilization device technique field, what relate generally to is a kind of water source, mining area comprehensive utilization device of hot water preparing.
Background technology
A large amount of waste water of mine and bath wastewater in process of production, can be discharged in colliery, have contained huge heat energy, have directly emitted, will cause great energy waste in these waste water.Device---the water resource heat pump of extraction water source heat energy existing ripe in the market, Lowlevel thermal energy, by a small amount of high-order electric energy input, shifts to high level heat by this device, can be used for refrigeration, heating, also can provide hot water.
Because the water quality requirement of common water resource heat pump main frame to water source is higher, and the waste water in mining area is mostly messy, also has corrosivity, therefore directly can not enter main frame.So some producers just develop sewage source heat pump main frame, but cost is too high, a lot of client can not accept.Under the prerequisite that this contradiction exists, a kind of source of sewage of intermediate heat transfer pattern that adopts utilizes technology to be born, exactly Intermediate Heat Exchanger is set between source of sewage and the heat source side of common water resource heat pump main frame, sewage discharges after Intermediate Heat Exchanger heat exchange, intermediary's water after Intermediate Heat Exchanger heat exchange as the thermal source of water resource heat pump host work, although technique reduces the cost of sewage intercepting well to a certain extent, lost a part of waste water heat.For the waste water heat source of some temperature lower than 15 DEG C, utilize technique to extract heat, the operating cost of equipment and maintenance cost all can improve greatly.In sum, the water utilization device operation strategies developed in the market is all comparatively single, and under the social overall background advocating economy, these water utilization devices are the consistent accreditations being difficult to meet coal mining.
Summary of the invention
The object of the invention is to water source, the mining area comprehensive utilization device proposing a kind of hot water preparing.This device the heat of the various waste water source of extracting directly can produce domestic hot-water, and do not need to use special sewage source heat pump main frame, do not need to adopt intermediate heat transfer pattern yet, greatly reduce the cost of sewage intercepting well, improve heat exchanger effectiveness, and can utilize the waste water heat source of temperature lower than 15 DEG C.
For achieving the above object, the technical solution used in the present invention is: a kind of water source, mining area comprehensive utilization device of hot water preparing, it forms primarily of heat pump main frame, water tank, open heat exchanger, water pump and cistern, the internal exchanger of described heat pump main frame only has condenser and does not have evaporimeter, and refrigerant inlet reserved on heat pump main frame is connected the refrigerant entry and exit on open heat exchanger with refrigerant exit correspondence; Described open heat exchanger is fixed in water tank, and it is connected in series in the coolant system heat exchanging pipe of heat pump main frame as evaporimeter; Described water pump is arranged in cistern, and it is communicated with water tank by pipeline.
The present invention is provided with porous water distributing plate directly over open heat exchanger in described water tank.
What open heat exchanger of the present invention adopted is fin tube structure, and the spacing of fin of finned tube adopts wide sheet distance to be 6 ~ 12mm.
The present invention is provided with pump screen pack at described water pump intake position.
Cistern of the present invention after filtration device is communicated with used heat water source.
Water pump of the present invention is by pipeline and the spray chamber being positioned at water tank upper, and spray chamber is made up of the space between water tank top board and porous water distributing plate.
The present invention is connected in series in the coolant system heat exchanging pipe of heat pump main frame owing to adopting open heat exchanger as evaporimeter, and be arranged in water tank, like this, the spent hot water of mining area discharge does not directly enter heat pump main frame, just the heat of the various waste water source of extracting directly can produce domestic hot-water, and not need to use special sewage source heat pump main frame, also not need to adopt intermediate heat transfer pattern, and can utilize the waste water heat source of temperature lower than 15 DEG C, greatly reduce the cost of sewage intercepting well.What adopt due to open heat exchanger is fin tube structure, and can draw more heats from water source, it is 5 DEG C that general heat exchanger tube extracts the water source temperature difference, and finned tube can extract 8 DEG C, therefore, effectively improves heat exchange efficiency.And the spacing of fin of finned tube adopts wide sheet apart from (6 ~ 12mm), be easy to cleaning, directly can use source of sewage, finned tube material is stainless steel, has good corrosion resistance.Owing to have employed three-stage filtration mode, i.e. the spent hot water of mining area discharge flows into cistern after device single filter after filtration and carries out two-stage precipitation filtration, then carries out pumping into water tank after three-stage filtration, the security reliability that the equipment that ensure that runs through pump screen pack.In addition, heat source water evenly sprays on the finned tube of open heat exchanger by porous water distributing plate, heat exchange is carried out with the refrigerant of fin Bottomhole pressure, refrigerant is fully vaporized, by the compressor work of heat pump main frame, this part low temperature heat energy is converted into high temperature heat, is exported, for miner provides the domestic hot-water of more than 45 DEG C by the condenser of heat pump main frame.
