[0028] Specific embodiment one, (see figure 1 , figure 2 ) The device of this embodiment consists of a housing 1, a valve body 2, a scraper 3, a filter element 4-1, a filter element 2 4-2, a water inlet 5, a water outlet 6, a connecting box 7-1, a connecting box Two 7-2, connecting port one 8-1, connecting port two 8-2, shaft 9 and rotating member 10, the filter element one 4-1 and the filter element two 4-2 are arranged on the housing 1, The housing 1 is provided with a water inlet 5 and a water outlet 6, a connecting box 7-1 and a connecting box 7-2 are connected to the housing 1, and a connecting box 7-1 and a connecting box 7-2 are respectively provided with Connecting port one 8-1 and connecting port two 8-2, the valve body 2 and the scraper 3 are fixed on the shaft body 9, and the shaft body 9 is connected with the rotating member 10.

[0029] Working principle: Sewage or surface water enters from the water inlet 5, and when it passes through the filter element 1-4-1, the ...

Example Embodiment

[0030] Specific embodiment two, (see image 3 ) The system of this embodiment is composed of a rotary two-prevention device 11, a heat pump unit or heat exchange device 12, a water pump 13, a water intake line 14-1, a drain line 14-2, and a connection line connecting the heat pump unit or heat exchange device 12 15-1 and 15-2, the water pump 13 is arranged on the water intake line 14-1, the water intake line 14-1 and the drainage line 14-2 are respectively connected with the water inlet and the water outlet of the rotary two-prevention device 11, the heat pump unit or The two interfaces of the heat exchange device 12 are respectively connected to the two connection ports of the rotary two-prevention device 11. The operating principle is the operating principle of the rotary two-prevention device 11.

Example Embodiment

[0031] Specific embodiment three, (see Figure 4 ) The difference between the system of this embodiment and the second embodiment is that a four-way reversing valve 17 and two connecting lines 16-1 and 16-2 are added, and the water pump 13 is arranged on the water intake line 14-1. The pipeline 14-1 and the drainage pipeline 14-2 are respectively connected to the water inlet and the water outlet of the rotary two-prevention device 11, and two of the ports of the four-way reversing valve 17 are respectively connected to the two connection ports of the rotary two-prevention device 11 The two ports of the heat pump unit or the heat exchange device 12 are connected to the other two ports of the four-way reversing valve 17 respectively. The operating principle is: when the valve body of the rotary two-prevention device 11 changes the direction of water flow or the action frequently affects the heat exchange of sewage or surface water, the four-way reversing valve 17 can be simultane...

Abstract

The invention discloses a cold and heat source revolution type dual-prevention device for sewage or surface water and a system thereof and relates to a device for preventing blocking and scaling while extracting cold and heat in sewage or surface water by utilizing a heat pump technology and a system thereof, belonging to the technical field of energy and aiming to effectively solve the problem of heat exchange equipment blockage by impurities in the sewage or the surface water and on how to reduce the growth thickness of dirt in the heat exchange equipment. The device comprises a shell, a valve body, a scraper, a filter piece 1, a filter piece 2, a water inlet, a water outlet, two connecting ports, a rotating component, and the like. The system comprises a heat pump set, the device, a connecting pipeline, and the like. When one filter piece works, the other filter piece is used for back washing, the rotating component intermittently changes the direction of the valve body to ensure that the two filter pieces are used for alternately filtering and back washing, and filtered sewage or surface water enters the heat pump set or the heat exchange device again to carry out cold and heat exchange. The invention is suitable for a cold and heat source system of the sewage or the surface water.

Description

technical field [0001] The invention relates to an anti-blocking and anti-scaling device 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 [0002] 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 utilization efficiency of the primary energy (coal, oil, natural gas) of the system can reach 133% or even 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 t...
