Description
Technical field
The invention belongs to sewage heat change system, relate to a kind of solar energy sewage source heat pump system of online self-cleaning enhanced heat exchange.
Background technology
The utilization of sewage cold-hot source, can alleviate current energy-intensive situation, have good energy-saving effect, environmental benefit and economic benefit, will save freshwater resources day by day in short supply, 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 with promoting is mainly because its water quality can not meet desired water standard in current water circulation system, in the middle of the engineering of actual motion, these dirts stop up water pump and heat exchanger often, cause systematic function obviously to decline, even can not move.
For addressing the above problem, take up an area the few filtering surface waterpower cyclic regeneration filter method of scalp and become the Perfected process that sewage cold-hot source utilizes, the main patent of filtering surface regeneration at present has ZL200410043654.9, ZL200720127607.1 and ZL200420031799.2 and automatic pollution removing device etc., its thinking is that scrubbing filtering surface (orifice plate filtering surface or orifice plate cartridge filter) is divided into filtering area and renewing zone two parts, utilize the water having filtered after participation heat exchange to carry out backwash to scrubbing filtering surface, alleviated to a great extent the blockage problem of large-scale dirt to water pump and heat exchanger.But because the dirty foreign material of sewage are too many, over-burden to cause filtering surface, and in Practical Project, such equipment fault occurs frequently.Because the hydraulic pressure of filtering surface renewing zone is higher than filtering area hydraulic pressure, cause the certainty of mixed water simultaneously, caused heat transmission equipment performance low.
Above-mentioned patent deficiency is still to contain small-sized particle and hair class dirt in the water source after its processing in addition, the water source that enters heat exchanger still can not meet national standard, heat exchange property is still not high, after the operation long period, still occur that dirt increases, especially the dirty foreign material of hair class stop up heat exchanger tube problem.For the current main method of blockage problem, be adopt 2.5-3m/s high flow rate, glueballs to clean and automatically clean the methods such as little brush.Although increase flow velocity method, can suppress gathering of dirt, because the increase of flow velocity causes a large amount of pumps consumptions, itself and energy-conservation original intention are disagreed; Glueballs cleans and automatically cleans little brush due to the reason results of use such as technique bad, thereby more employing overseas equipments and cause larger investment.For the not high problem of heat exchange property, be mainly at present that the area that strengthens heat exchanger solves, but will increase the investment of system like this.Application number is 201210269219.2 the disclosed a kind of Large Diameter Pipeline shell-tube type fluid bed sewage heat exchanger of patent, has designed the devices such as solid-liquid separator, can be fine solution heat exchanger clean problem, yet can not self anti-cleaning.
Simultaneously, in China most areas, especially the water source heat pump units of northern area is in the process of operation, the temperature of sewage often only has tens degrees Celsius, through filtering after the processes such as heat exchange, the water temperature that enters intermediary's water of water resource heat pump often only has 8 degrees Celsius of left and right, causes the Inlet and outlet water temperature difference too small, make water source heat pump units cannot normal boot-strap the situation of operation often occur.
Summary of the invention
The deficiency that the present invention exists in order to overcome above-mentioned prior art, effectively solve dirt and cross the problems such as the much and little heat exchanger tube causing that differs stops up, dirt increases, heat exchange efficiency is low, mechanical disorder, and winter intake water temperature too low be difficult to start problem, a kind of dirt that filters arbitrary size is provided, in conjunction with the heliotechnics of cleanliness without any pollution, has improved the solar energy sewage source heat pump system of the online self-cleaning enhanced heat exchange of water inlet water temperature simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
Whole system comprises trunk sewer, mechanical grille, primary pump, automatic pollution removing device, two stage pump, heat exchanger inlet pipeline, hair filter, counter-flushing pipeline, circulation pipe, control valve a, control valve b, control valve c, control valve d, control valve e, sewage heat exchanger, solid-liquid separator, heat exchanger water return pipeline, solar panels, circulating pump, water source heat pump units, energy storage water tank, control valve f, control valve h; Sewage in trunk sewer is removed large-scale dirty foreign material through mechanical grille, and the sewage after scrubbing, in primary pump suction automatic pollution removing device, is further removed dirty foreign material; Sewage after filtration is extracted by two stage pump, and it is divided into two parts, and a part enters automatic pollution removing device; Another part enters hair filter by heat exchanger inlet pipeline, sewage after filtration enters sewage heat exchanger and participates in heat exchange together with the solid particle of separating in solid-liquid separator, delivery port at sewage heat exchanger connects solid-liquid separator, after the sewage that sewage after Separation of Solid and Liquid enters heat exchanger water return pipeline and automatic pollution removing device converges, return in mechanical grille, after the dirty foreign material in backwash machinery grid, enter trunk sewer; In four sewage pipes that sewage heat exchanger connects, control valve b, control valve c, control valve d, control valve e are set respectively, by the switching of control valve switch, plumbing drain are carried out to backwash.The sewage heat change face of sewage heat exchanger carries out the coating such as copper facing or plating fluorine to be processed to prevent and the formation that suppresses dirt.Sewage heat exchanger connects water source heat pump units after connecting energy storage water tank, wherein energy storage water tank with can be connected by plate very much, control valve h one end connects sewage heat exchanger delivery port, the other end connects water source heat pump units water inlet, thereby heat solar panels being absorbed by intermediary's water passes to the water inlet water temperature that intermediary's water of sewage heat exchanger improves water source heat pump units.
When intermediary's water water temperature can not reach the temperature of start, control valve f is opened, control valve h closes, and intermediary's water enters energy storage water tank and carries out exchange heat, thus the temperature of intermediary's water is improved, and reaches turn-on temperature water source heat pump units is normally moved; When the water temperature of intermediary's water is during higher than turn-on temperature, control valve f is closed, control valve h opens, and intermediary's water directly enters into water source heat pump units, and water source heat pump units is normally moved.
Benefit of the present invention and effect are, thoroughly solve sewage and utilized medium-and-large-sized dirty foreign material blocking pipe as Cooling and Heat Source, hair obstruction heat transmission equipment, because dirt causes heat transmission equipment bulky and cause heat transmission equipment hydraulic performance decline because of mixed water, the problems such as fault, utilize this clean energy resource of solar energy simultaneously, improve water inlet water temperature, avoid causing into water water temperature is too low the situation that sewage source heat pump unit cannot normal boot-strap, significantly improve system heat exchange property, guarantee that security of system is reliable and stable, can be used for sewage or surface water to utilize heat pump techniques to carry out cold and heat supply as low level Cooling and Heat Source, or refrigerating industry equipment, high-efficiency environment friendly.
