Abstract
The utility model discloses a primary dirty water source heat pump system of indirect, including sewage trunk canal, sewage buffer pool, sewage in -take pump, centrifugal dirty water heat exchanger, intermediary's water working shaft, heat pump set and terminal working shaft, the sewage buffer pool includes the inlet tube, and inlet tube department is provided with the valve, is provided with behind the valve to smash formula grating de -dirt machine, smashes formula grating de -dirt machine front end and is provided with removable cover, and sewage buffer pool rear end is provided with the drain pipe. The utility model discloses a dirty water heat exchanger of the substituted traditional shell and tube formula of centrifugal dirty water heat exchanger, the dirty water heat exchanger of this kind have advantages such as coefficient of heat transfer height, corrosion resistance and anti jam ability reinforce, have reduced heat exchanger front end water treatment facilities, sewage water intaking heat exchanger buries in the room fully, but above -mentioned closing cap or plant the lawn beautify the environment, and equipment noise is low, rubbish need not the outward transport, does not have secondary pollution to the surrounding environment.
Description
Technical field
This utility model relates to the application of untreated sewage source heat pump technology.
Background technology
Use sewage source heat pump system that urban original wastewater is utilized, there is energy-conserving and environment-protective, the advantage such as pollution-free.Sewage source heat pump system can be divided into indirect type system and direct-type system according to system form, current direct-type system is the most immature because of its technology, apply less, general employing indirect type system, i.e. sewage is introduced into intermediate heat transfer device, carry out heat exchange with intermediary water, entered source pump by intermediary's water the most again and carry out heat exchange.
On Practical Project, the Main of indirect type untreated sewage source heat pump system is at present: as shown in Figure 1, sewage in trunk sewer 101 flows into sewage Buffer Pool 102, then filtered to mechanical filter 104 by one-level sewage pump 103 water intaking, then heat exchange is carried out by B-grade sewage pump 105 water intaking to sewage heat exchanger 106 and intermediary's water, intermediary's water after heat exchange enters source pump 108 by intermediary's water feed pump 107 and carries out heat exchange, carries out heat supply finally by end feed pump 109.Its major defect is that energy resource consumption is high, floor space is big, and rubbish needs conveying equipment or labor cleaning, and surrounding enviroment can be caused secondary pollution.And ground need to build operation control room, operator are the most on duty, time-consuming effort.
Utility model content
The purpose of this utility model is to provide a kind of indirect type untreated sewage source heat pump system, overcomes the shortcoming of existing indirect type untreated sewage source heat pump system with not enough, promotes the economy of untreated sewage source heat pump system water taking heat-transfer further.
The technical scheme that this utility model provides is:
A kind of indirect type untreated sewage source heat pump system, including trunk sewer, sewage Buffer Pool, sewage intake pump, centrifugal sewage heat exchanger, intermediary's water feed pump, source pump and end feed pump, described sewage Buffer Pool includes water inlet pipe, valve it is provided with at water inlet pipe, grinding grid dirt removing machine it is provided with after valve, grinding grid dirt removing machine front end is provided with removable cover, and sewage Buffer Pool rear end is provided with drain pipe.
It is provided with guide rail on described grinding grid dirt removing machine.
It is provided with catch pit dredge pump in described sewage Buffer Pool.
This utility model provides the benefit that: 1) use centrifugal sewage heat exchanger to replace traditional shell tube-type sewage water heat exchanger, and this sewage heat exchanger has the advantages such as heat transfer coefficient height, corrosion resistance and anti-blockage capability are strong, decreases heat exchanger front end water treatment facilities；
2) grinding grid dirt removing machine is used to substitute original swinging grid sewage-removing machine, suspension in sewage and floating refuse can be ground into fine particle, flow with sewage, it is not necessary to supporting screw conveyor, press apparatus, deodorizing device, rubbish outward transport equipment etc., reduced investment；And rubbish is without outward transport, without outward transport expense.
3) sewage water taking heat-transfer machine room is the most buried, can cover above or plant lawn, beautifying the environment, and equipment noise is low, and rubbish is without outward transport, to surrounding non-secondary pollution.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 2,3, a kind of indirect type untreated sewage source heat pump system, including trunk sewer 1, sewage Buffer Pool 2, sewage intake pump 3, centrifugal sewage heat exchanger 4, intermediary's water feed pump 5, source pump 6 and end feed pump 7, described sewage Buffer Pool 2 includes water inlet pipe 21, valve 22 it is provided with at water inlet pipe 21, being provided with grinding grid dirt removing machine 25 after valve 22, grinding grid dirt removing machine 25 front end is provided with removable cover 23, and sewage Buffer Pool 2 rear end is provided with drain pipe 7.Sewage in trunk sewer 1 flows in sewage Buffer Pool 2 by water inlet pipe 1, sewage Buffer Pool 2 water inlet arranges grinding grid dirt removing machine 5, grinding grid dirt removing machine 5 front end arranges removable cover 23 with holes, most sewage and sufficiently small granule can flow into sewage Buffer Pool by removable cover and spotter, in sewage, oarse-grained suspension and floating refuse are then ground into the fine particle of 6 ~ 10mm, dirt after pulverizing is without salvaging, directly enter flow channel type or centrifugal sewage heat exchanger with sewage, enter again in trunk sewer after heat exchange.Sewage, after sewage Buffer Pool 2, enters centrifugal sewage heat exchanger 4 by sewage intake pump 3 and carries out heat exchange with intermediary's water, and the intermediary's water after heat exchange enters source pump 6 by intermediary's water feed pump 5 and carries out heat exchange, carries out heat supply finally by end feed pump 7.
Guide rail 24 it is provided with on grinding grid dirt removing machine 25.Grid carries installation guide rail, only need to put it in fixed guide rail during installation, and crushing type grid is lightweight, volume is little, it is not necessary to arrange large-scale lifting appliance, by suspension ring, equipment can all hang out pond and overhaul during maintenance, without reserved bigger overhaul of the equipments passage between grid, therefore use grinding grid dirt removing machine to substitute original swinging grid sewage-removing machine, the floor space of water taking heat-transfer machine room can be reduced, reduce civil engineering costs.Catch pit dredge pump 26 it is provided with in sewage Buffer Pool 2.Sewage in catch pit in sewage Buffer Pool can be discharged by catch pit dredge pump 26.
