Abstract

The invention discloses a rotating drum type block prevention device for a sewage or surface water source heat pump system, and belongs to the technical field of energy sources. The rotating drum type block prevention device solves the problems that heat-exchange equipment and a pipeline of the sewage or surface water source heat pump system are blocked, backflushing return water is mixed with inflow water, suspended matters are wound at a filter opening, and the sealing difficulty and the working accuracy difficulty are high in the existing block prevention device. The rotating drum type block prevention device comprises a housing, a speed reduction driving mechanism, a rotating shaft, a rotating drum filtering surface, a ring baffle and division plates, wherein the interior of the housing is divided into two chambers by the ring baffle; the rotating drum filtering surface is arranged in one chamber; each chamber is divided into two non-communicated sewage or surface water chamber units by each division plate; and four water openings are communicated with the four chamber units respectively. The rotating drum type block prevention device is used for block prevention of sewage or surface water, and has the advantage of simple and reliable structure.

Description

technical field [0001] The invention relates to an anti-blocking device for a sewage or surface water source heat pump system, belonging to the technical field of energy. Background technique [0002] Using heat pump technology to extract cold heat from low-grade renewable clean energy to provide heating and air conditioning for buildings is one of the effective ways to save energy and reduce emissions in buildings, and its energy saving rate can reach more than 45%. These low-level renewable clean cold and heat sources include: the atmosphere, soil, groundwater, surface water, urban sewage, etc. When using these cold and hot energy sources, on the one hand, it needs to be utilized according to local conditions, and on the other hand, it is necessary to effectively solve some common and key technologies question. Regarding the cold and heat sources of urban raw sewage, the key issues that need to be solved include blockage, fouling and efficient heat transfer, and blockage ...
