Description
Technical field
The utility model belongs to sewage source heat pump system, particularly relates to a kind of sewage source heat pump system be coupled with solar energy.
Background technology
The utilization of sewage cold-hot source, current energy-intensive situation can be alleviated, have good energy-saving effect, environmental benefit and economic benefit, will freshwater resources day by day in short supply be saved, for new field is opened up in using energy source, for comprehensive full use water resource provides a new thinking.Why sewage cold-hot source does not have large area to use and promotes mainly because its water quality can not meet water standard required in current water circulation system, in the middle of the engineering of actual motion, these dirts block water pump and heat exchanger often, cause systematic function obviously to decline, even can not run.
For solving the problem, industry utilizes the plant equipment such as spotter to carry out backwash scrubbing and rotary machinery grid, need when fetching water from trunk sewer to arrange a water intaking pond, water intaking porch, pond arranges a rotary machinery grid, in water intaking pond, arrange water pump for supplying water to spotter, such whole system can get the less sewage of suspension.
But there is two problems in such system, first a water intaking pond is set, water intaking pond after a period of operation silt particle there will be deposition, along with the mud in water intaking pond is cumulative, after a cycle of operation, mud can water pump to burying, even can not pull out water pump, its water intaking function is also just lost.The scheme of current solution is, labor cleaning, and utilize car of removing contamination to carry out soil pick-up, each cycle of operation spends about 5-7 ten thousand yuan.Burden is brought to operation.Second Problem is, owing to only arranging a water intaking pond, and a rotary machinery grid is only set, the impurity particle do not grudged in sewage can only through single filter, if select the rake teeth grid gap of rotary machinery grid comparatively large, large granular impurity can be leaked through, if rake teeth grid gap is less, then water flow can be affected.
Run into extreme cold weather on the other hand, often because sewage temperature is too low, cause water source heat pump system not start shooting, affect heat supply.
Utility model content
The deficiency that the utility model exists to overcome above-mentioned prior art, solves that silt particle accumulates in water intaking pond shadow water pump, rotary machinery grid arranges the problems such as not enough effectively, provides a kind of sewage source heat pump and solar association heating system.
The utility model solves the technical scheme that its technical problem adopts: whole system comprises trunk sewer, one-level water intaking pond, in described one-level water intaking pond, one-level rotary machinery grid is set, one-level water pump, sludge pump, secondary water intaking pond, in described secondary water intaking pond, 2 stage rotary mechanical grille is set, secondary water pump, secondary water pump is ined succession sewage water supply line, sewage water supply line arranges hair filter, after hair filter, shell and tube exchanger is set, the tube side of shell and tube exchanger is sewage, shell side is the water purification with its heat exchange, the sewage that tube side is discharged is discharged through sewage water return pipeline, sewage water return pipeline is connected to the foreign material charging conduit of 2 stage rotary mechanical grille, the foreign material charging conduit of one-level of ining succession again rotary machinery grid, finally be connected to trunk sewer downstream, sludge pump is also connected to trunk sewer downstream by pipeline,
The shell side outlet pipeline of shell and tube exchanger is divided into two-way, one tunnel arranges valve A and is connected to water resource heat pump water inlet, another kind ofly arranges two valve B, between two valve B, arrange boiler, boiler is connected to solar thermal collector by water pipe and water pump, and water resource heat pump is used for heating and refrigerating.
During Winter heat supply, can valve-off A, open two valve B, the water of boiler heats by solar thermal collector work, mixes with the water purification from shell and tube exchanger, enters the evaporimeter of water resource heat pump as the mouth of a river, and water source heat pump heating is user's heating.When extreme cold weather, the heat that solar thermal collector brings can make the water temperature entering water source heat pump evaporator improve, and avoid because sewage temperature is too low, system can not normally be run.
Benefit of the present utility model and effect be,
The setting of two-stage rotary machinery grid, can filter bulky grain and granule impurity respectively, provide the sewage needed for shell-tube type sewage heat exchanger, ensures that tube side does not block; Arrange sludge pump in one-level water intaking pond when in system night or can not run, open at any time, the impurity such as the mud deposited in pond of one-level being fetched water are discharged to trunk sewer downstream, ensure that one-level water pump is normally fetched water.According to measuring and calculating, for the annual scrubbing cost of this system of the buildings of 50,000 square metres at about 10,000 yuan, and 1 year only need clear up once.Simultaneously, the arranging of solar units can ensure the normal operation of sewage source heat pump under extreme weather in winter, and the hot water that heat supply at ordinary times also can adopt solar thermal collector to bring in the winter time mixes with the water purification after shell and tube exchanger heat exchange, the temperature of such water inlet water source heat pump units improves, and then water source heat pump units efficiency is provided, very favourable to the operation of whole sewage source heat pump system.
