Abstract
The invention discloses a crude sewage source heat-pump station system, which supplies cold and heat for buildings in a centralized manner. The crude sewage source heat-pump station system comprises a sewage feeding pump, a sewage circulating pump, a medium-water circulating pump, a water-source heat pump unit and an air-conditioning circulating pump and also comprises a full-automatic water-taking cleaning machine, a self-cleaning heat exchanger, a sewage pond and a pressed sewage channel, wherein the sewage feeding pump is arranged near the sewage pond and is connected with the full-automatic water-taking cleaning machine by a pipeline; the sewage circulating pump is arranged behind the full-automatic water-taking cleaning machine and beforein front of the self-cleaning heat exchanger; the medium-water circulating pump is arranged between the self-cleaning heat exchanger and the water-source heat pump unit; a sewage outlet of the self-cleaning heat exchanger is connected with the full-automatic water-taking cleaning machine and the pressed sewage channel simultaneously; and a water discharging port of the full-automatic water-taking cleaning machine is connected to the pressed sewage channel. The crude sewage source heat-pump station system disclosed by the invention has the advantages that large centralized heat supplying and refrigeration can be realized, and the cold-heat energy in sewage is furthest recycled, so that the energy is saved and the emission is reduced.
Description
Technical field
The present invention relates to a kind of heat supply, cooling system, relate in particular to a kind of water resource heat pump central heating, cooling system.
Background technology
Along with the rapid popularization of water source heat pump technology in China, the untreated sewage source heat pump technology also obtains certain development and application.This technology from urban original wastewater winter heat-obtaining, summer, heat release utilized regenerative resource, realized recycling economy.A difficult problem of utilizing urban original wastewater to do the Cooling and Heat Source maximum of heat pump air conditioner unit is how to prevent that impure sewage is to pollution and the obstruction of pipeline, heat transmission equipment.China takes its place in the front ranks of the world to this solution of problem, the full-automatic water-taking spotter that Dalian preserves light company to make has not only been realized the obstruct to foreign material in the sewage, also possesses simultaneously the function of impurity such as removing fibrous dirty foreign material such as animal hair, need not carry out the labor cleaning, realize full-automatic.The self-cleaning heat exchanger of their research and development can thoroughly solve pollution and the blockage problem of sewage heat exchanging equipment in addition.Yet reasonable design untreated sewage source heat pump air-conditioning system how is related to investment, the operating cost of a project even the success or failure of project.
Usually, when utilizing the untreated sewage source heat pump system heating and refrigerating, the water intaking place can be selected in from the nearest trunk sewer of building, though easy to use like this, be subjected to the restriction of the trunk sewer water yield, be unfavorable for that extensive central heating is cold.It is the facility that converges sewage and concentrate pressurized delivered that municipal sewage promotes pumping plant, and this facility has cesspool, if water intaking from then on, heated pump station scheme reasonable in design can realize extensive central heating, refrigeration in its vicinity.
Summary of the invention
For making untreated sewage source heat pump system realize that extensive central heating is cold, the present invention has designed a kind of rational native sewage source heat pump station system.
System comprises sewage feed pump, sewage (waste water) recirculating pump, intermediary's water-circulating pump, water source heat pump units, air-conditioning circulating pump, also comprises full-automatic water-taking spotter, self-cleaning heat exchanger, cesspool, sewer with pressure; The sewage feed pump is set near cesspool, link to each other with full-automatic water-taking spotter by pipeline, sewage (waste water) recirculating pump is arranged on behind the full-automatic water-taking spotter before the self-cleaning heat exchanger, intermediary's water-circulating pump is set between self-cleaning heat exchanger and the water source heat pump units, the outlet of sewer of self-cleaning heat exchanger links to each other with sewer with pressure with full-automatic water-taking spotter simultaneously, and the discharge outlet of full-automatic water-taking spotter is connected to sewer with pressure.
The invention has the beneficial effects as follows: near native sewage source heat pump station system reasonable in design municipal sewage promotes pumping plant, can realize extensive central heating, refrigeration, recycle to greatest extent the cold and hot energy in the sewage, save reduction of discharging.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is schematic diagram of the present invention.
Among Fig. 1,1. sewage feed pump, 2. full-automatic water-taking spotter, 3. sewage (waste water) recirculating pump, 4. self-cleaning heat exchanger, 5. intermediary's water-circulating pump, 6. air-conditioning circulating pump, 7. water source heat pump units, 8. cesspool, 9. sewer with pressure.
The specific embodiment:
This native sewage source heat pump station system comprises sewage feed pump 1, sewage (waste water) recirculating pump 3, intermediary's water-circulating pump 5, full-automatic water-taking spotter 2, self-cleaning heat exchanger 4, water source heat pump units 7, air-conditioning circulating pump 6, cesspool 8, sewer 9 with pressure.Sewage feed pump 1 is fetched water from cesspool 8, be transported to full-automatic water-taking spotter 2, sewage enters self-cleaning heat exchanger 4 by sewage (waste water) recirculating pump 3 after filtering, cold in the sewage or heat are delivered in intermediary's water, sewage part after the heat exchange is returned full-automatic water-taking spotter 2, another part directly returns sewer 9 with pressure, intermediary's water is entered into condenser or the evaporimeter heat exchange of water source heat pump units 7 by intermediary's water-circulating pump 5, return self-cleaning heat exchanger 4 after the heat exchange, preparation cold water or hot water pass through air-conditioning circulating pump 6 to the building cooling after water source heat pump units 7 actings, heat supply.
In the present embodiment, sewage (waste water) recirculating pump 3 must be greater than the pressure of sewer 9 with pressure to the pressure of sewage;
The discharge sum that the discharge that sewage feed pump 1 is got from cesspool and sewer with pressure 9 are got from the pond is sewer 9 former design discharges with pressure.
Realized under the prerequisite that does not affect the normal conveying function of sewage in the pressure line by this system, recycled the cold resource of used heat in the sewage.And the Energy Efficiency Ratio of system is very energy-conservation more than 4.
