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 heat exchanger special for sewage utilizing source of sewage to be 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 making heat supply in winter and cooling in summer consumption become energy resource consumption gradually.Create the product of a lot of economize energy: wherein heat pump solves part heating and the requirement of freezing for this reason, but be subject to the place restriction of distribution of water resources and earth source heat pump, can not apply widely.The utilization of source of sewage, can alleviate current energy-intensive situation, have good energy-saving effect, 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 why these Cooling and Heat Source do not have large area to use and promote mainly because its water quality can not meet water standard required in current water circulation system, the normal dirt containing blocking heat transmission equipment in source of sewage, effectively removing dirt to ensure that flow system flow abundance is stablized is the precondition that source of sewage can utilize.But the water treatment technology such as chemical, biochemical is very high due to investment, operating cost, does not have feasibility; Source of sewage containing filth amount is large, and traditional scrubbing facility such as large-scale filter screen, mechanical grille needs larger investment and takes up an area space, thus limits the Application and Development on a large scale of source of sewage; Therefore the technological means that physical filtering just becomes a kind of key is carried out to sewage, take up an area the Perfected process that the few continuous regenerate filtration method of filtering surface waterpower of scalp becomes source of sewage utilization.
At present, based on the regeneration issues of scrubbing filtering surface, main patent has ZL200410020630.1, ZL200420031799.2, ZL200410043654.9 and ZL 200720127607.1 etc., its main thought is utilize the sewage after filtering to carry out backwash to scrubbing filtering surface, alleviate the blockage problem of dirt to water pump and heat transmission equipment to a great extent, but owing to adding filter plant, system process relative complex, trouble point is relative with maintenance point increases.
At present, do not increasing in the sewage source heat pump system of filter plant, wide runner heat exchanger is adopted to be one comparatively reasonably technological means, its architectural feature is that sewage and intermediary's water walk respective runner respectively, sewage runner and intermediary's water flow passage cross section are rectangle, each surface of sewage runner is planar structure, this just causes the runner plane being arranged in bottom easily makes dirty foreign material deposit in drainage flow process, and easily fouling, have impact on design of heat exchanger performance, the serious system that causes cannot be run.
Summary of the invention
In order to overcome the deficiency that prior art exists, effectively solve dirt blocking and prior art be realize technological process that anti-clogging causes complicated with occupation of land the problem such as huge, propose a kind of dirt by arbitrary size in sewage, whole heat-exchange system front end does not need to arrange the heat exchanger special for sewage of filtering and deterring 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 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, successively through intermediary's water side runner, intermediary's water baffle pipe, intermediary's water outlet pipe; Sewage enters from sewage water inlet pipe, passes through left side sewage bobbin carriage, the special runner of sewage, right side sewage bobbin carriage successively, then from right side sewage bobbin carriage baffling to the special runner of next sewage, is finally discharged by sewage outlet pipe; Intermediary's water is contrary all the time with the flow direction of sewage, countercurrent flow.
Adopt sewage special runner to prevent dirt from blocking heat transmission equipment, the intermediary's water outside the special runner of sewage becomes countercurrent flow with sewage, this heat-exchanger rig heat exchange efficiency is high, anti-clogging, anti-dirt, anticorrosive and easy cleaning.During source of sewage utilizes, front end does not need to arrange filtration and deters device, simplify the technological process of whole system, reduce the fault point, thoroughly solve complex process that dirt blocking causes with anti-clogging and take up an area the problems such as huge, significantly improve systematic function, can, using sewage as low level Cooling and Heat Source, heat pump techniques be utilized to carry out cold and heat supply, or refrigerating industry equipment.
The invention has the beneficial effects as follows, the special runner of sewage is up-narrow and down-wide structure, and sewage is greater than water at flow process Midst density, dirty foreign material are at the easier smooth outflow in wider lower end, and sewage stronger by property, is not easy to form dirty foreign material deposition, also not easily scrape foreign material, be not easy fouling.
