Abstract
A vacuum super conductive heat pipe exchanging device comprises a case for water with water inlet and outlet, chimney channels formed by heat conductive material, the said chimney channel fixed inside the case, when the smoke inlet of the channel connected with the smoke outlet boiler, smoke outlet connected with the air or dedust inlet, boiler smoke will change heat with the water inside the case.The heated water can be used for multi purpose, saving boiler coal 10%-25%. It can also reduce the temperature of the boiler, improve the running environment of the deduster to improve its durability.
Description
Technical field
The present invention relates to a kind of heat-exchanger rig, relate in particular to a kind of heat recovery that can boiler smoke is entrained, the device that is reused.
Background technology
Produce flue gas after coal burns in boiler, contain toxic gas and dust in these flue gases, also contain a large amount of heat energy simultaneously, known technology is often only paid attention to the elimination to toxic gas and dust, deduster for example is set, after the dedusting of boiler smoke process deduster, enters atmosphere again.Do like this, though solved certain environmental issue, the heat in the flue gas does not but obtain utilizing, and has been lost in vain.Simultaneously, the heat in the boiler smoke can have a negative impact to deduster, at high temperature works for a long time, greatly reduces the service life of deduster, has increased the environmental protection cost.
Especially for coal-fired steam boiler, after water is heated to form steam, need supplementing water in boiler constantly.If what replenish is normal-temperature water, normal-temperature water is heated to boiling, will consume a large amount of fire coals, if what replenish is the condensed condensed water of steam, generally at 30～40 ℃, though situation can be better, the thermal efficiency increases, but still unsatisfactory.
Summary of the invention
Technical problem to be solved by this invention provides a kind of superconducting heat pipe, this device in recirculated water, is reused the heat recovery in the boiler smoke by simple structure again, not only save the energy, and improved the thermal efficiency of boiler.
For solving the problems of the technologies described above, technical scheme of the present invention is: superconducting heat pipe, comprise a casing that is used to be filled with water, described casing is provided with water inlet and delivery port, it also comprises the exhaust gases passes that is made of Heat Conduction Material, described exhaust gases passes is fixed in box house, and described exhaust gases passes has the mouth that advances that can be connected with the pipe of boiler, and can directly communicate with atmosphere or can be connected outlet flue with the flue dust import of deduster.
As a kind of improvement, the tube wall of described exhaust gases passes is provided with some heat abstractors, and described heat abstractor is made of the vacuum heat-conduction pipe that heat-conducting medium is housed.
As a kind of specific embodiment, described heat-conducting medium is an absolute ethyl alcohol, and the can amount of described absolute ethyl alcohol accounts for 10%～25% of described metal tube cavity.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: owing to be provided with exhaust gases passes in the described casing, exhaust gases passes is made of Heat Conduction Material, so when the mouth that advances of exhaust gases passes is connected with the pipe of boiler, its outlet flue communicates with atmosphere or when being connected with the flue dust import of deduster, water just carries out exchange heat by exhaust gases passes in boiler smoke and the casing.After water in the water tank is heated, multiple use can be arranged,, can save boiler fired coal 10%～25% if be applied to coal-fired steam boiler.Moreover, boiler smoke is reduced through temperature behind this heat-exchanger rig, and the flue gas after the cooling enters deduster, has improved the running environment of deduster, has increased the service life of deduster.
Because the tube wall of described exhaust gases passes is provided with some heat abstractors, described heat abstractor is made of the heat pipe that heat-conducting medium is housed, described heat pipe is a vacuum metal pipe, described heat-conducting medium is an absolute ethyl alcohol, at first absolute ethyl alcohol absorbs heat in the heat pipe hot junction, volatilization absorbs big calorimetric simultaneously for gas.Gas motion is met condensation and is become liquid to cold junction, discharges big calorimetric.The liquid of condensation comes back to the hot junction under the gravity effect, enter next circulation.According to above-mentioned principle, heat-conducting medium can not be filled in the vacuum heat-conduction pipe, must leave certain evaporating space, could improve its heat-conducting effect, facts have proved, when heat-conducting medium adopts absolute ethyl alcohol, its can amount should account for 10%～25% of described metal tube cavity, best results.Extracting vacuum in the pipe can guarantee the not managed interior air pressure influence of vaporization of liquid.The moment heat conduction of this heat pipe, the two ends isothermal even still can operate as normal under the very little situation of cold junction and warm end temperature difference, thereby have been accelerated heat exchange efficiency.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
Superconducting heat pipe as shown in drawings, comprise a casing that is used to be filled with water 2, described casing 2 is provided with water inlet 3 and delivery port 4, the top of described casing 2 is provided with at least one gas outlet 21, it also comprises the exhaust gases passes 1 that is made of Heat Conduction Material, described exhaust gases passes is fixed in casing 2 inside, and it advances mouth and be connected with the pipe of boiler, and its outlet flue directly communicates with atmosphere or is connected with the flue dust import of deduster.
The tube wall of described exhaust gases passes 1 is provided with some heat abstractors 11; Described heat abstractor 11 is made of the vacuum heat-conduction pipe that heat-conducting medium is housed, described heat-conducting medium is an absolute ethyl alcohol, absolute ethyl alcohol is also not exclusively filled the vacuum heat-conduction pipe, but to leave certain evaporating space, its can amount had better not surpass 1/2 of whole vacuum heat-conduction pipe, facts have proved that the can amount of absolute ethyl alcohol accounts for 10% of described metal tube cavity～25% o'clock best heat-conducting effect.Described heat-conducting medium also can adopt known other the heat-conducting medium of those skilled in the art.Described heat pipe stretches into the inside of described exhaust gases passes 1, has both strengthened the contact area of the tube wall of the cigarette that has heat and exhaust gases passes 1, has also extended the holdup time of cigarette in exhaust gases passes 1, helps the carrying out of heat exchange more.
Described water inlet 3 is arranged at the bottom of casing 2, and described delivery port 4 is arranged at the top of casing 2, helps circulating of water; Because described exhaust gases passes 1 takes the shape of the letter U, make the bottom of exhaust gases passes 1 locate just to have entered in the middle of the cold water of casing 2 simultaneously always, help heat exchange.
The bottom of described exhaust gases passes 1 is provided with the dedusting mouth 5 that stretches out described casing 2 outsides, and described dedusting mouth 5 places are provided with seal cover 6, and dust removal process is carried out in can be regular seal cover 6 be opened by 5 pairs of described exhaust gases passes 1 of dedusting mouth.
