Abstract
The invention provides a heat exchanger special for a sewage source heat pump. Dirt with optional sizes in sewage can pass through the heat exchanger, and a filter anti-blocking device is not required to be arranged at the front end of an entire heat exchange system. The entire heat exchanger device comprises an intermediate water inlet tube, an intermediate water outlet tube, an intermediate water baffling tube, an intermediate water side flowing way, special sewage flowing ways, a sewage inlet tube, a sewage outlet tube, sewage channels and a shell, wherein intermediate water enters the intermediate water inlet tube, and sequentially flows through the intermediate water side flowing way, the intermediate water baffling tube and the intermediate water outlet tube; sewage enters the sewage inlet tube, sequentially flows through a left sewage channel, one of the special sewage flowing ways and a right sewage channel, then is baffled to the next special sewage flowing way, and finally is drained out of the sewage outlet tube; and the flowing direction of the intermediate water is always opposite to that of the sewage, so that countercurrent flow is formed. The special sewage flowing ways have structures with narrow tops and wide bottoms, the density of the sewage is greater than that of water in a flowing process of the sewage, and the sewage can flow at lower ends of the special sewage flowing ways smoothly.
Description
Technical field
The present invention relates to a kind of heat-exchanger rig, especially a kind of source of sewage of utilizing is the sewage source heat pump dedicated heat exchanger of Cooling and Heat Source.
Background technology
In recent years, China advocates energy-saving and emission-reduction energetically, encourages the application of energy-conserving product.Wherein urban development, urban population increase the importance that makes heat supply in winter and refrigeration consumption in summer become gradually energy resource consumption.Produced the product of a lot of energy savings: wherein heat pump has solved partly heating and the requirement of freezing for this reason, but is subject to the place restriction of distribution of water resources and earth source heat pump, can not use widely.The utilization of source of sewage can be alleviated present energy-intensive situation, and good energy-saving effect is arranged, and saves freshwater resources day by day in short supply, for new field is opened up in using energy source, for comprehensive full use water resource provides a new thinking.And these Cooling and Heat Source why do not have large tracts of land to use and popularization mainly is because its water quality can not satisfy desired water standard in the present water circulation system, often contain the dirt that stops up heat transmission equipment in the source of sewage, effectively remove dirt to guarantee that sufficient the stablizing of flow system flow is the precondition that source of sewage can be utilized.But the water treatment technology such as chemical, biochemical does not have feasibility because investment, operating cost are very high; The source of sewage containing filth amount is large, and the scrubbing facilities such as traditional large-scale filter screen, mechanical grille need larger investment and take up an area the space, thereby has limited the on a large scale Application and Development of source of sewage; Therefore sewage is carried out the technological means that physical filtering just becomes a kind of key, taking up an area the few filtering surface waterpower cyclic regeneration filter method of scalp becomes the Perfected process that source of sewage is utilized.
At present, regeneration problem based on the scrubbing filtering surface, main patent has ZL200410020630.1, ZL200420031799.2, ZL200410043654.9 and ZL 200720127607.1 etc., its main thought is for utilizing the sewage after filtering that the scrubbing filtering surface is carried out backwash, alleviated to a great extent the blockage problem of dirt to water pump and heat transmission equipment, but owing to increased filter plant, and the system process relative complex, the trouble point is relative with maintenance point increases.
At present, in the sewage source heat pump system that does not increase filter plant, adopting wide runner heat exchanger is a kind of comparatively reasonably technological means, its architectural feature is that sewage and intermediary's water are walked respectively runner separately, sewage runner and intermediary water flow passage cross section are rectangle, each surface of sewage runner is planar structure, this has just caused the runner plane that is arranged in the bottom easily to make dirty foreign material deposition in the drainage flow process, and easily fouling, affected the design of heat exchanger performance, the serious system that causes can't move.
Summary of the invention
The deficiency that exists in order to overcome prior art, solve effectively that dirt stops up and prior art for the technological process that realizes anti-clogging and cause complicated with the problems such as occupation of land is huge, propose a kind of dirt by arbitrary size in the sewage, whole heat-exchange system front end need not arrange and filter the sewage source heat pump dedicated heat exchanger that deters device.
The technical solution adopted for the present invention to solve the technical problems is: whole device comprises intermediary's water water inlet pipe, intermediary's water outlet pipe, intermediary's water baffle pipe, intermediary's water side runner, the special-purpose runner of sewage, sewage water inlet pipe, sewage outlet pipe, sewage bobbin carriage and shell; Intermediary's water enters from intermediary's water water inlet pipe, passes through successively intermediary's water side runner, intermediary's water baffle pipe, intermediary's water outlet pipe; Sewage enters from sewage water inlet pipe, passes through successively left side sewage bobbin carriage, the special-purpose runner of sewage, right side sewage bobbin carriage, the special-purpose runner from right side sewage bobbin carriage baffling to next sewage then, is finally discharged by the sewage outlet pipe; Intermediary's water is opposite all the time with the flow direction of sewage, countercurrent flow.
Adopt sewage special use runner to prevent that dirt from stopping up heat transmission equipment, the outer intermediary's water of the special-purpose runner of sewage becomes countercurrent flow with sewage, high, the anti-obstruction of this heat-exchanger rig heat exchange efficiency, anti-dirt, anticorrosive and easily cleaning.Front end need not arrange to filter and deter device in the source of sewage utilization, simplify the technological process of whole system, reduce the fault point, thoroughly having solved dirt stops up the complex process that causes with anti-clogging and takes up an area the problems such as huge, significantly improve systematic function, can utilize heat pump techniques to carry out cold and heat supply with sewage as the low level Cooling and Heat Source, or refrigerating industry equipment.
The invention has the beneficial effects as follows, the special-purpose runner of sewage is up-narrow and down-wide structure, sewage in flow process density greater than water, dirty foreign material are easier smooth and easy flowing in wider lower end, and the trafficability characteristic of sewage is stronger, is not easy to form dirty foreign material deposition, also be difficult for scraping foreign material, be not easy fouling.
