Description

Fluorine Lyons-sewage heat exchanger
Technical field
The present invention relates to heat-exchange apparatus, particularly relate to fluorine Lyons-sewage heat exchanger.
Background technology
Utilize municipal sewage as Cooling and Heat Source, by sewage source heat pump building is carried out heating air conditioning, can directly reduce the consumption of other short energy, can also reach simultaneously the purpose of twice laid, be resource regeneration, develop a circular economy, build a conservation-minded society, the important measures of friendly environment.
Sewage source heat pump has been realized the recycling of city used heat, turns waste into wealth, and is that novel renewable and clean energy resource utilizes technology, the requirement of meet sustainable development, building a resource-conserving society.The water source heat pump system technology is combined with municipal sewage, utilizes scope, expand and have far reaching significance aspect the urban sewage treatment benefit enlarging municipal sewage.
Sewage source heat pump is the states of matter circulation change that relies on the agent of source pump internal refrigeration storage, absorbs heat winter from sewage, and to building heat supplying, the heat transferred sewage in the building, thereby realize cooling by source pump summer after source pump heats up.Sewage has substituted cooling tower, has the outstanding advantages such as energy-efficient, environmental protection, safe and reliable, a tractor serves several purposes.
At present, sewage source heat pump system has obtained propagation and employment in most of city of China, such as: the ground such as Beijing, Tianjin, Shanxi, Shandong, Shijiazhuang, Xinjiang, Guangxi.
Along with the raising of entire society's energy savings, environmental consciousness, the application of sewage source heat pump is also in continuous expansion.Except in urban heat supplying refrigeration, produce the domestic hot-water uses, also all be applied in food, biochemistry, pharmaceuticals industry, plantation cultivation and agricultural byproducts processing storing field.Further all kinds of reproducible low-temperature heat sources of digging utilization or used heat thermal source improve and promote the sewage source heat pump technology, towards setting up conservation-minded society's development.
Sewage source heat pump can be divided into direct-type sewage source heat pump and indirect type sewage source heat pump two classes.In the direct-type system, with the medium of sewage heat change be cold-producing medium, in the indirect type system, with the medium of sewage heat change be intermediary's water or anti-icing fluid.Between the former sewage and the cold-producing medium through the direct heat transfer of heat exchanger wall; There is intermediary's medium in latter, thereby heat transfer resistance increases, and causes heat pump system efficiency to descend thereupon.The direct-type system is Disciplinary Frontiers and the developing direction of present sewage source heat pump research.
The direct-type system compares with the indirect type system very large advantage, mainly is:
1, under same water condition, confess the heat of as much, evaporating temperature can improve about 5 ℃, and source pump efficient is greatly improved, and the total power consumption of system can reduce more than 15%.
2, saved sewage heat exchanger and corresponding intermediary water circulation water pump, the machine room floor space reduces, and not only greatly reduces civil engineering and investment of equipment, and reduces pump energy consumption.
3, obtain the heat of as much, required sewage quantity can reduce about half.The temperature difference loss of heat exchange in the middle of the indirect type system need to consider, this has just limited the cooling extent of sewage.
When adopting native sewage water to be thermal source, generally all adopt the filters such as filter screen, grid, Automatic sieve filter, sewage is processed.Although before source pump, sewage is filtered fully, fluorine Lyons-sewage heat exchanger generally all can not long-time steady operation, so, fluorine Lyons-sewage heat exchanger that current China makes Cooling and Heat Source with native sewage water is also rare, the sewage source heat pump that document is reported almost is the indirect type sewage source heat pump.The indirect type sewage source heat pump is owing to the impact of the intermediate systems such as sewage heat exchanger, and sewage resource utilizes cost large, and invest and operating cost is also larger.
Although utilize fluorine Lyons-sewage heat exchanger superiority obvious, saved sewage heat exchanger, heating efficiency and operating cost all are better than the indirect type sewage source heat pump,, the development of current fluorine Lyons-sewage heat exchanger is also insufficient, and reason is:
1, direct sewage source heat pump system requires the evaporator/condenser of source pump can " device is dual-purpose ", and evaporator/condenser has been proposed specific (special) requirements.
2, the source pump of use fluorine Lyons-sewage heat exchanger needs through specially treated, and technical difficulty is larger.Although people have a lot of imaginations and test, Shortcomings.
3, the direct-type system requirements is done larger transformation to the evaporator/condenser of source pump, and corresponding producer is less.Indirect type sewage source heat pump, sewage directly do not advance unit, and the sewage-water-to-water heat exchanger before the required unit is succeeded in developing.
Up to the present, also do not popularize widely fluorine Lyons-sewage heat exchanger system; The sewage source heat pump technology has adopted the indirect type system since being born substantially, and this is the conservative measure of taking from the consideration of reliability angle.
Realize being to utilize sewage as the key problem in technology of heat pump Cooling and Heat Source, especially for fluorine Lyons-sewage heat exchanger without stopping up Continuous Heat Transfer.Solving obstruction and the pollution of abominable water quality heat exchanging equipment and pipeline, realize anticorrosion and pollution-free heat exchange, is a worldwide technological puzzle.The impact of municipal sewage water quality heat exchanger mainly contains corrosion and scaling and obstruction.Common way is between municipal sewage and heat pump, and sewage filter device and sewage-water-to-water heat exchanger are set, and intermediary's water of heat pump absorbs heat from sewage, or in the sewage release heat.Sewage behind the positive energy exchange from return pipe, turns back in the exhaust system of municipal sewage.
Because sewage viscosity is large, the coefficient of heat transfer is low, sewage heat exchanger must be done very hugely; When with sewage as the Cooling and Heat Source of heat pump, sewage must purify, and through a sewage-water-to-water heat exchanger of additionally setting up before unit, and heat or the cold of sewage is delivered to heat pump intermediary water, this process will cause energy loss, reduce the Energy Efficiency Ratio of heat pump.If sewage without strict purification, without sewage-water-to-water heat exchanger, directly enters heat pump, sewage and cold-producing medium directly carry out heat exchange, and the sewage flow pipeline in the heat pump is usually blocked soon, to such an extent as to heat pump can not be worked fully.
The sewage filter device that before sewage heat exchanger, arranges, its filter bores can not be very little, otherwise sewage filter device is blocked soon.Such sewage filter device can solve the blockage problem of sewage heat exchanger, but the tiny sticky contaminant in the sewage, can pass through sewage filter device, enter sewage heat exchanger, constantly in the inner sedimentation of sewage heat exchanger, in heat exchanger plates surface deposition, fouling, the heat exchanger plates surface resistance of heat transfer is increased, and the heat exchanger overall performance degenerates soon.
In industrial or agricultural and people's lives, discharge various sewage.Sewage heat exchanger and common heat exchanger condition of work have very large difference, the method for designing of common heat exchanger, and use experience can not simply be used for sewage heat exchanger.Although the method for designing of common heat exchanger and manufacturing process are all very ripe,, the sewage heat exchanger science design method so far, does not also have fine solution.

Fig. 3 has provided the freon pipe road figure of fluorine of the present invention Lyons-sewage heat exchanger embodiment.
The freon pipe road of fluorine of the present invention Lyons-sewage heat exchanger embodiment, it comprises two parts: pipeline is regulated in heat-transfer pipe and fluorine Lyons, and heat-transfer pipe comprises: heat-transfer pipe 220, heat-transfer pipe 225, heat-transfer pipe 245, heat-transfer pipe 250, heat-transfer pipe 270 and heat-transfer pipe 275; Fluorine Lyons is regulated pipeline and is comprised: fluorine Lyons import 210, inlet tube 212, female pipe 215, female pipe 230, female pipe 240, female pipe 255, female pipe 265, female pipe 280, unsteady flow pipe 235, outlet 260 and fluorine Lyons outlet 290.
Two one-tenth are a pair of up and down for heat-transfer pipe, and an end of paired up and down two heat-transfer pipes connects up and down, and this port is referred to as closed end, and the other end, the heat-transfer pipe port that joins with female pipe is referred to as openend.
In the freon pipe road, fluorine Lyons process of circulation is as follows:
1, as fluorine Lyons evaporimeter, fluorine Lyons import 210 below, fluorine Lyons outlet 290 is up;
2, fluorine Lyons enters heat exchanger from import 210 and inlet tube 212, flows into female pipe 215.The outlet of female pipe 215 connects heat-transfer pipe 220, but this is not a pipe, but a heat-transfer pipe row, usually is made of several or tens heat-transfer pipes.
3, then the heat-transfer pipe 225 by the next flow process of heat-transfer pipe 220 inflows enters female pipe 230.
4, manage 230 out from mother, enter unsteady flow pipe 235.The effect of unsteady flow pipe 235 is from fluorine Lyons that heat-transfer pipe 225 flows out, to enter two female pipes through unsteady flow pipe 235, i.e. female pipe 240 and female pipe 265.Then, flow into respectively again two heat-transfer pipe rows, i.e. heat-transfer pipe 245 and heat-transfer pipes 270.
This be because, in the heat-transfer pipe 225 of the heat-transfer pipe 220 of first pass and the second flow process, fluorine Lyons is heated, partial gasification, mobile volume increases, the flow area that flows must enlarge, otherwise flow resistance is excessive.
5, fluorine Lyons one road enters heat-transfer pipe 250 from heat-transfer pipe 245, and another road enters heat-transfer pipe 275 from heat-transfer pipe 270.Then enter respectively female pipe 255 and female pipe 280.
6, fluorine Lyons from mother manage 255 and female pipe 280 flow out, enter outlet 260, last, export 290 outflow heat exchangers from fluorine Lyons.
7, if as fluorine Lyons condenser, the structure of heat exchanger is constant, and just the flow direction in fluorine Lyons is opposite, enters heat exchanger from the top, behind the steam condensation of fluorine Lyons, flows out from the below.
8, inlet tube 212, unsteady flow pipe 235 and outlet 260 can be located at outside the box heat exchanger, also can be placed in the casing, are also placed in the sewage runner, carry out heat exchange with sewage.
9, the unsteady flow pipe can be more than one, and to two combs, or two combs are to four combs such as a comb, or four combs to six stream comb etc., respectively establish a unsteady flow pipe; But outlet only has one, and it is before outlet, converges the fluorine Lyons among each pipe row of last flow process, focuses in the outlet unified outflow fluorine Lyons outlet 290.
Heat-transfer pipe is carbon steel pipe, be immersed in the sewage runner of level, the two-end structure of horizontally disposed heat-transfer pipe is different, one end is openend, the mouth of pipe of openend is received fluorine Lyons and is regulated pipeline, and the other end is closed end, and the mouth of pipe of the closed end of two heat-transfer pipes is connected up and down, per two heat-transfer pipes form one horizontal U-shaped loop; The openend of heat-transfer pipe places outside the box heat exchanger usually, regulates pipeline by fluorine Lyons, through openend, injects fluorine Lyons from heat-transfer pipe acceptance or to heat-transfer pipe; The heat-transfer pipe setting party to effluent stream to parallel, sewage can not the transversal flow heat-transfer pipe.
The adjustable pipe route fluorine Lyons import of fluorine Lyons, inlet tube, several female pipe, several unsteady flow pipe, outlet and the export mixes of fluorine Lyons, it communicates with the openend of each heat-transfer pipe, receives or supply with fluorine Lyons of each heat-transfer pipe.When fluorine Lyons is subjected to thermal evaporation in heat-transfer pipe, volume increases, or condensation heat, smaller volume, pipeline is regulated by changing the heat-transfer pipe radical in fluorine Lyons, changes circulation area, reaches the purpose of regulating flow velocity, prevents that flow velocity is too high, increase flow resistance, prevent that also flow velocity is excessively low, impact is conducted heat.
Fig. 4 has provided the overall construction drawing of fluorine of the present invention Lyons-sewage heat exchanger embodiment.
Fluorine of the present invention Lyons-sewage heat exchanger embodiment is a kind of special shell-and-tube heat exchanger, and its profile is a case structure.
Space in its casing 115 is the runner of sewage, a lot of deflection plates 140 and back flow plate 160 are arranged, and an end of deflection plate 140 and back flow plate 160 has upper and lower opening, and sewage is by these openings, enter next horizontal flow process by a upper horizontal flow process, the mobile of sewage turned; Heat-transfer pipe placed side by side in the sewage runner, parallel with flow direction, along deflection plate and back flow plate, also turn, effluent stream and heat-transfer pipe row are non-intersect.Heat-transfer pipe is seamless steel pipe, is cold-producing medium freon in the pipe.
The left upper end of box-shaped casing 115 has sewage import 110.After sewage enters heat exchanger, along the sewage runner of level, the heat-transfer pipe 275 in the parallel baffled sewage runner, the purpose of the fluorine Lyons heat exchange in realization sewage and the heat-transfer pipe.
In the sewage runner, the internal layer runner 130 between heat-transfer pipe 275 and deflection plate 140, its height are not less than 1 centimetre, and internal layer runner 130 flow velocitys are slower, conduct heat slightly poor.Outer runner 120 outside heat-transfer pipe, this is the sprue of sewage, and flow velocity is very fast, and heat exchange is better, and it highly is not less than 3 centimetres.Internal layer runner 130 and outer runner 120 communicate, and by heat-transfer pipe row's gap, the sewage of two-layer runner can exchange, and heat-transfer pipe row's gap can not be less than 1 centimetre.The internal layer runner is positioned at the upper and lower surface of deflection plate 140, and all the other are outer runners, comprises the upper lower flow channel of back flow plate 160, all is outer runner.
Sewage flows, from the top down from a flow process to another flow process when the baffling mouth 150 of the end of the deflection plate 140 of flowing through.In heat exchanger, after sewage is finished heat exchange, drain from outlet of sewer 190.
Freon enters heat exchanger from fluorine Lyons import 210 of heat exchanger lower left, at first arrives female pipe 215, manages 215 heat-transfer pipe rows in the heat exchanger through mother.Through come and go flowing of a level, namely experience two flow processs after, fluorine Lyons enters unsteady flow pipe 235.From two outlets of unsteady flow pipe 235, fluorine Lyons enters two heat-transfer pipe rows simultaneously, and cross section of fluid channel amasss and increases, and this is the gasification because fluorine Lyons is heated, and the volume that flows enlarges, and necessary simultaneously circulation expansion area is with limited flow rate and flow resistance.At last, by two heat-transfer pipe rows, comprising heat-transfer pipe 275, through outlet, arrive fluorine Lyons outlet 290, outflow heat exchanger.
Deflection plate 140 and back flow plate 160 all are the dividing plates in the heat exchanger.Deflection plate 140 and back flow plate 160 are alternate settings, and namely a deflection plate is followed a back flow plate, follow a deflection plate, another back flow plate again.The open-ended opposite direction of deflection plate and back flow plate, a upper on the left side opening, next just opening on the right, the like, from top to bottom, form continuous segmental baffle, and arcuate flow path.
Sewage is along arc runner, and is from top to bottom, tortuous mobile; In the arc heat-transfer pipe of freon in arcuate flow path, flow from bottom to top.This is for the heat exchanger as evaporimeter, if condenser, flow direction is all opposite.Water and freon heat exchange be countercurrent flow always, can obtain best heat-transfer effect.
At the heat exchanger shell of box-shaped, on the facade side plate adjacent with the baffling mouth, corresponding each runner has a Butterworth Hatch 152.Utilize Butterworth Hatch, can put in camera and observe the inner incrustation situation of heat exchanger, in case of necessity, utilize high pressure water jet pipe, clean by Butterworth Hatch heat exchanger inner flow passage.
In order to prevent the corrosion of sewage heat exchanger, to the inner surface of casing 115, the both side surface of deflection plate 140, the outer surface of the both side surface of back flow plate 160 and heat-transfer pipe 275 is all wanted surface treatment.Wherein, the outer surface of heat-transfer pipe can be electroplated corrosion resistant metal, such as: chromium, nickel, all the other plate body surfaces can adopt baking vanish anticorrosion.
Fig. 5 is the outline drawing of fluorine of the present invention Lyons-sewage heat exchanger embodiment.
Fluorine Lyons-sewage heat exchanger of fluorine of the present invention Lyons-sewage heat exchanger embodiment is the horizontal shell and tube type heat exchanger, and its casing is hexahedral box-shaped.
In the casing of box-shaped, heat-transfer pipe is horizontally disposed with, and freon flows in heat-transfer pipe, and sewage is outside pipe.In order to improve the flow velocity of the outer sewage of pipe, deflection plate and the back flow plate of polylith level is housed in heat exchanger, form the runner of the multiple-layer horizontal of sewage.
Flow in pipe in cold-producing medium fluorine Lyons, filling amount is few, and flow velocity is higher, easily solves the problem that lubricating oil returns compressor.In addition, because sewage is outside heat-transfer pipe, heat-transfer pipe can bursting by freezing.
Fluorine of the present invention Lyons-sewage heat exchanger embodiment both can be used as evaporimeter, also can be used as condenser.
When it during as evaporimeter, fluorine Lyons enters heat exchanger from fluorine Lyons import 210, through several flow processs, through unsteady flow pipe 235, passes through outlet 260 again, from the sewage heat absorption, sewage is lowered the temperature, the evaporation of fluorine Lyons, fluorine Lyons steam is from fluorine Lyons outlet 290 outputs.Sewage enters from the sewage import 110 of heat exchanger top, discharges from the outlet of sewer 190 of heat exchanger below.
When it during as condenser, import and export on the contrary, fluorine Lyons steam enters heat exchanger from the top, fluorine Lyons steam conducts heat to sewage, sewage is heated, condense in fluorine Lyons, liquid fluorine Lyons is from the output of heat exchanger below.Sewage then enters from the below, flows out from the top.
Heat convection is always taked in sewage and fluorine Lyons, can obtain best heat transfer effect.
Adopt the horizontal shell and tube type heat exchanger of fluorine Lyons in pipe, as fluorine of the present invention Lyons-sewage heat exchanger embodiment, mainly be to consider when it is used as evaporimeter the lubricating oil in the cold-producing medium, can along with the flow at high speed of tube refrigerant, return together compressor.Particularly when adopting fluorine Lyons as cold-producing medium, this almost is the unique form that can select, because lubricating oil is lighter than fluorine Lyons, if outside heat-transfer pipe, is difficult to separate.
