Abstract
A provided filter unit capable of automatically backwashing sewage water consists of an A and a B sewage water filter systems, when one sewage water filter system is in a filtering state, the other is in a backwashing state, and each sewage water filter system consists of a filter, an inflation capsule valve, a sewage water pump, a frequency-conversion control cabinet, an air compressor, solenoid valves and a compressed air connecting pipe. When the sewage water pump in the A system is started, an exhaust solenoid valve of an inflation pipe on the inflation capsule valve is opened for exhausting, an inflation solenoid valve is closed, the inflation capsule valve is opened, sewage water flows into the filter, when the filtered sewage water is transported to a water source heat pump unit through the sewage water pump for heat exchange, the heat-exchanged sewage water flows back to the filter in the B filter system through a return pipe, then the sewage of a filter material is washed off and taken away, the sewage water flows back to a sewage water pipe net through a water return pipe, and thus the filter and backwashing process is finished; and the water pump in the B system is started, then the B system is operated as the operation process of the A system so that the sewage water automatically filtering and backwashing process is realized. The filtered sewage water can directly enter into a condenser or an evaporator of the water source heat pump unit, and the heat exchange is carried out, and therefore the heating or cooling efficiency is improved.
Description
Technical field the present invention relates to a kind of improvement of automatically backwashing sewage water filter bank.
Technical background energy-saving and emission-reduction, environmental protection are the themes of Economic Development, and the sewage source heat pump is used fast-developing in the heat supply and air conditioning engineering.At present, as the utilizing in the process of the cold and heat source of water source heat pump units, the technical subject matter that exists is that sanitary sewage impurity stops up sewage pump, stops up heat exchanger at sanitary sewage, affect the safe operation of heating, air-conditioning system, although people have done many research work, develop some new equipments,, sewage pump often occurring stops up, the phenomenon of sewage mixed flow, system failure rate is high, and the problem that heat exchange efficiency is low still exists; Because the sewage disposal device work under bad environment, automation equipment is difficult to reliability service, the invention provides a kind of cost low, and efficient is high, manageability, the automatically backwashing sewage water filter bank of safe and reliable operation.
Summary of the invention the invention provides a kind of automatically backwashing sewage water filter bank, in order to solve sewage scrubbing problem, becomes possibility for the sewage source heat pump unit provides without bulky grain suspension sewage.
The present invention is comprised of A, two identical sewage filter systems of B, when one of them is in filtration condition, another is in the backwash state, each system by filter, aerated capsule valve, sewage pump, frequency-conversion control cabinet, air compressor, energising open the outage shut electromagnetic valve, the outage opens solenoid valve is closed in energising and the compressed air tube connector forms.Every filter is comprised of intake chamber, suction chamber, water inlet pipe, screen cloth, filtrate, suction hose, return pipe, water-break pipe, check-valves.Sewage water inlet pipe connects the sewage regulating reservoir, and water inlet pipe is provided with the aerated capsule valve, and when the unit sewage pump was out of service, the aerated capsule valve all was in closed condition, and air compressor machine is in automatic mode, inflates to the aerated capsule valve.The open and close of aerated capsule valve are also being controlled in the start and stop of frequency-conversion control cabinet control sewage pump, magnetic valve on the compressed air hose of aerated capsule valve opens and closes along with the startup of sewage pump, when one of them system's sewage pump starts, the energising of this system is opened the outage shut electromagnetic valve and is opened Quick air-discharge, the closed electromagnetic valve that outage is opened is closed in energising, the aerated capsule valve is deflated to be opened, sewage flows to intake chamber through water inlet pipe, through screen cloth, pass filtrate, enter suction chamber, the sewage after the filtration is through suction hose, sewage pump, outlet pipe is transported to water source heat pump units and carries out heat exchange, the suction chamber of sewage after the heat exchange in return pipe flow back into the filter of another system passes screen cloth, filter material layer, dirt sticking on the filtrate is rinsed out and takes away, through the water-break pipe, check-valves flows back to sewage network, finishes and filters and backwash process; When the native system sewage pump out of service, system's sewage pump starts in addition, repeat the above-mentioned running of last system, previous filtration condition becomes the backwash state, this process can replace the operation that uninterruptedly moves in circles, the water pump alternate run time, can determine according to test, realize like this process of sewage automatic fitration and backwash, the source of sewage of fine qualities is provided for the sewage source heat pump unit, can directly enter condenser or the evaporimeter of water source heat pump units through the sewage that filters, carry out heat exchange, reduce investment outlay, reduce fault, raising heats or refrigerating efficiency.
