Description
Technical field
The utility model is related to a kind of heat power engineering, and in particular to a kind of big temperature difference heat-exchanger rig of freon.
Background technology
In recent years, continuing to develop with China's urban construction, the contradiction between regional development and heat demand is also increasingly
Highlight.All city cities area is all constantly expanding, and main city zone scale cell is continuously increased, and old town significantly increases newly every year
Area, the area of Xincheng District also constantly expands.From the thermal source and heat supply network heat capacity of current city, city is much can not meet
The need for city's fast development.If heat supply does not catch up with, it will urban development is met with bottleneck.To solve this concerning urban development
With the contradiction of common people's vital interests, various regions generally start centralized heating project construction, increase area of heat-supply service newly, increase engineering newly and throw
Money.Specifically include newly-built pipe-networks engineering, the old net improvement project in part, newly-built booster pump station, Ji Kong control centres, newly-built heat exchange station
And heat exchange station improvement project etc..
Heat supply improvement project is divided into heat source side and heat supply network side：
Heat source side generally comprises unit heat supply transformation and heat supply initial station construction project, and specially power plant and power ＆ light company is new
Increase networking area of heat-supply service, Xincheng District boiler room heat supply network area of heat-supply service, district heating company heat supply network area of heat-supply service etc..
Heat supply network side is mainly to be changed to the pipeline of old town extended active duty, and heat supply pipeline can be controlled effectively after changing
Evaporating, emitting, dripping or leaking of liquid or gas processed, greatly reduces because stopping hot number of times caused by tube leaks, greatly improves heating effect.
Central heating is realized in certain old town in nineteen eighty-three September, and pipe network has run 27 years so far.Through measurement, 1985
10mm when the old pipe network caliber that year installs by installing originally is thinned to 4~6mm, and severe local corrosion, and in the heat supply phase
Often there is leakage event.Heating network section of tubing has extended service in the army, and often occurs tube leaks phenomenon during heat supply, leads
Heating quality is caused to decline.If do not transformed, once there are tube leaks, must stage stop heat, this can to resident living
Cause very big influence.Power ＆ light company's investment is transformed old town heating network, changes all thinning and corrosion pipeline,
About 5 kilometers of the reconstruction scope pipe network total length, is related to 570,000 square meter area of heat-supply services, is roughly equal to the family of user 5000, injects capital into 17,000,000 yuan.
After the completion of engineered, the stability of the district heating quality and heat supply is greatly improved.By pipe network improving, main city zone thermal source fills
Foot, can bear the normal heat supply of resident, retail shop and enterprise.
Most of certain power plant's heat supply main pipeline network construction service life, what is had was even up to 30 years all more than 18 years.This portion
It is in charge of net because building time is long, along with the period of construction technical matters falls behind, to making insulation, overcoat serious damage, pipe network
Aging, seriously corroded.In recent years, supervisor's net leakage accident frequently occurred, and each runtime occurs tens times.In every submain
During net repairing, repair personnel all suffers from more than 95 DEG C high pressures, the threats of high-temperature water, and repairing every time sluices all small up to more than 30
When, cause large area residential building to stop heat, the serious situation of part underground pipe network bursting by freezing.Central heating secondary network aspect is present
Problem is also more protruded, especially early stage building and pipe abandon arcola room heat supply building grid-connected in recent years, the aging corrosion of pipe network
As many as the weight of degree, quantity seriously threaten the normal life of city heat supply safety and influence resident.
666 kilometers of certain heat supply group heating network length, wherein once netting long 165 kilometers, secondary network is long 501 kilometers.
About 400 kilometers are built before nineteen ninety-five.Because most of pipeline network construction times are long, aging seriously corroded, pipe network system is caused
Evaporating, emitting, dripping or leaking of liquid or gas is extremely serious, and radiation loss reaches 0.35 GJ/square metre year.The average temperature drop of every kilometer of heat distribution pipe network is all 2
More than DEG C, the average percentage of water loss of pipe network system is about 3%.Because fluid loss is big, heat is lost seriously, almost all of once net,
The hydraulic misadjustment problem of secondary network all various degrees, because pipe network is aging and without forensic science regulation, therefore heating enterprise
The heating quality of user is difficult to ensure that in heat supply.
In decades, central heating cause for China city development construction and living standards of the people raising be made that weight
Big contribution.Nowadays the outstanding problem that the central heating network of large area is aging, seriously corroded has become influence central heating, sternly
Heat supply safety and common people's normal life in city are threaten again.
It has been the task of top priority for carrying out city heat supply work to implement central heating network transformation.Can be significantly by pipe network improving
The evaporating, emitting, dripping or leaking of liquid or gas of pipe network high is dropped, and drop high-energy source consumption energy saving improves energy utilization rate；Can look forward to heat supply by pipe network improving
Sparetime university's amount uses of the new technology, new technology, improves the science regulating power of heating enterprise, improves overall heat supply level；By pipe network
Transformation can General Promotion heating system safety and heat supply supportability, improve constantly the use thermal mass of numerous residents, benefit
The common people.It is the act benefited the nation and the people to implement central heating network transformation, early to implement early being benefited.
Implement central heating network improvement project, emphasis is exactly to remove waste and old heat supply pipeline, lay the new pipeline of heat supply, this is needed
Put into huge fund.How to accomplish using existing pipeline, or less or thinner pipeline can be laid, only spend less
Investment, can equally reach the heating load of needsThis is the frequent problem thought deeply of scientific worker that designs and construct.
