specific Embodiment approach 1

[0040] Specific implementation mode one (see figure 1 ), the method of this embodiment is realized in this way: use the water pump to pump sewage or surface water into the heat pump unit or heat exchange device for heat exchange, discharge it after heat exchange, and discharge it on the water inlet and outlet pipelines of the heat pump unit or heat exchange device Set up a filter part separately, and change the water flow direction intermittently and regularly by setting up a four-way reversing valve. When one filter part filters, the other is backwashed. A certain amount of rubber balls, when the four-way reversing valve is reversed, the rubber balls are driven by the water flow to descale the heat pump unit or heat exchange device, so as to realize the non-blocking and efficient transfer of cooling heat from sewage or surface water.

specific Embodiment approach 2

[0041] Specific implementation mode two (see figure 1 ) The system of this embodiment consists of a water pump 1, a water intake pipeline 2-1, a drainage pipeline 2-2, a four-way reversing valve 3, a filter component 5-1, a filter component 2 5-2, a heat pump unit or a heat exchange The device 7, the rubber ball 10 and the connecting pipeline 4-1, 4-2, 6-1, 6-2 are composed, the water pump 1 is arranged on the water intake pipeline 2-1, and the sewage or surface water of the four-way reversing valve-3 enters , the water outlet are respectively connected with the water intake pipeline 2-1 and the drainage pipeline 2-2, and one interface of the filter part 5-1 is connected through the

[0042] The connecting line 4-1 is connected to one port of the four-way reversing valve 1, the other port is connected to a port of the heat pump unit or heat exchange device 7 through the connecting line 6-1, and one of the filter parts 2 5-2 The interface is connected to one interface of the f...

specific Embodiment approach 3

[0043] Specific implementation mode three (see figure 2 ), the difference between the system of this embodiment and the second embodiment is that a four-way reversing valve two is added between the connecting pipeline 6-1, the connecting pipeline 6-2 and the filter part 1 5-1 and the filter part 2 5-2 8 and connecting pipelines 9-1, 9-2, one interface of the filter element 5-1 is connected with one interface of the four-way reversing valve 3 through the connecting pipeline 4-1, and the other interface is connected through the connecting pipeline 9-1 It is connected with one port of four-way reversing valve 2 8, one port of filter part 2 5-2 is connected with one port of four-way reversing valve 1 3 through connecting pipeline 4-2, and the other port is connected through connecting pipeline 9 -2 is connected to an interface of the four-way reversing valve 2 8, and the sewage or surface water inlet and outlet of the four-way reversing valve 2 8 are respectively connected to the...

Abstract

The invention discloses an application method and an application system for sewage or earth surface water cold and heat sources, relates to a method and a system for extracting cold heat in the sewage or earth surface water by using heat pump technology, belongs to the technical field of energy, and aims to solve the problem that impurities in the sewage or earth surface water block heat exchange equipment and to reduce scaling growth thickness inside the heat exchange equipment. The sewage or earth surface water is extracted by a water pump to enter a heat pump unit or a heat exchange device for heat exchange, and the sewage or earth surface water subjected to heat exchange is discharged; a filtering component is respectively arranged on an inlet / outlet pipeline of the heat pump unit or the heat exchange device; the water flow direction is intermittently changed on time by a four-way reversing valve; the other filtering component is subjected to back flush when one filtering component performs filtration; and a certain number of rubber balls are arranged in the system simultaneously, and when the four-way reversing valve reverses, the rubber balls are driven by the water flow so as to descale the heat pump unit or the heat exchange device. The method and the system have the advantage of guaranteeing no-blockage and high-efficiency transmission of the cold heat of the sewage or earth surface water.

Description

[0001] technical field [0002] The invention relates to a method and system for extracting cold heat from sewage or surface water by using heat pump technology, and belongs to the field of energy technology. Background technique [0003] Using heat pump technology to extract cold heat from low-grade, renewable clean energy for heating and air conditioning of buildings is one of the effective ways to save energy and reduce emissions in buildings. These low-level renewable clean cold and heat sources include: the atmosphere, soil, groundwater, surface water, urban sewage, etc., and their temperature is between 0 and 20°C in winter. When they are used as cold and heat sources for heat pumps, heat pumps The primary energy (coal, oil, natural gas) utilization efficiency of the system can reach 133% or higher, and the energy saving rate can be more than 45%. But when using these cold and hot energy sources, in addition to using them according to local conditions, some key proble...
