Description

A kind of horizontal integrated thermal heat exchanger

Technical field the utility model relates to a kind of heat-pipe heat exchanger.

Background technology is present, industries such as oil, chemical industry, iron and steel, electric power are for the energy-conservation temperature that the high-temperature flue gas that produces in the technical process is improved the combustion-supporting cold medium that equipment such as boiler need use by heat exchange, enter next technological process separately after reaching pre-provisioning request.This just need reach the purpose of heating-cooling by this equipment of heat exchanger, consumes to save the energy, to reduce.Its structure of horizontal heat exchange of heat pipe that is widely used now mainly is: heat pipe fills the vacuum tube of heat-transfer working medium in being, some above-mentioned heat pipes are formed the heat pipe bundle, their middle part is fixed on the vertical sagging plate, two ends place respectively on the end tube sheet, and from the horizontal by certain inclination angle, on the end limit of above-mentioned sagging plate and end tube sheet both sides, be provided with side plate its with the square tube of two upper and lower openings of above-mentioned three tube sheets formation, one of them is cold dielectric chamber, another is a smoke chamber, and their two ends are respectively equipped with the import and export pipe.Be provided with bobbin carriage plate in addition with its containing in the outside of two ends tube sheet.The weak point of above-mentioned heat exchange of heat pipe is: two kinds of cold media of a heat exchanger preheating simultaneously, if want two kinds of cold media of preheating simultaneously, just need processing that the heat exchange of heat pipe of two platform independent is installed, so just improved equipment cost, cause unnecessary economic loss, also do not meet energy-saving and cost-reducing requirement.

The summary of the invention the purpose of this utility model is to provide that a kind of equipment manufacturing cost is low, a kind of horizontal integrated thermal heat exchangers little, two kinds of cold media of preheating simultaneously take up room.The utility model mainly includes: heat pipe bundle, sagging plate and end tube sheet, smoke chamber, cold dielectric chamber, smoke entrance pipe, cold medium I, cold medium II import and export pipe and bobbin carriage plate.Wherein, heat pipe fills the vacuum tube of heat-transfer working medium in being, preferably heat pipe is provided with helical fin or fin or fin or ailhead etc. outward, and some above-mentioned heat pipes constitute two groups of heat pipe bundles.The middle part of these two groups of heat pipe bundles is fixed on separately on the vertical sagging plate and is tightly connected, so that flue gas and cold medium are separated.Preferably connect by flange seal, promptly flange sealing surface compresses filler and can guarantee sealing between cold and hot fluid, is convenient to change separately the heat pipe that lost efficacy or damaged again.The two ends of above-mentioned two groups of heat pipe bundles place respectively in each self-corresponding two ends tube sheet through hole, and every group of heat pipe bundle is from the horizontal by 2 °～20 ° inclination angles.The end tube sheet high-order corresponding with heat pipe is the outer end tube sheet, and the end tube sheet corresponding with the heat pipe low level is inner tube sheet, and two inner tube sheet tops link to each other, and tube sheet outside, two outer ends is respectively equipped with the bobbin carriage plate with its containing.On the end limit of above-mentioned two sagging plates and end tube sheet both sides, be provided with biside plate, itself and sagging plate and end tube sheet constitute the square tube of four upper and lower openings, adjacent centre two square tubes are two smoke chambers, and their two ends up and down are a shared flue gas inlet tube and a smoke outlet tube respectively; The square tube of both sides is two cold dielectric chambers, the opening of each cold dielectric chamber upper/lower terminal links to each other with the upper and lower opening of upper and lower transition case respectively, each transition case outwards respectively is provided with the side opening of the opposite direction of smoke-box (promptly towards), and they are respectively the import or export of two kinds of cold media.These two kinds of cold media can be identical gas, also can be different gas.

The course of work of the present utility model is as follows: the high-temperature flue gas that enters from flue gas inlet tube is under the two inner tube sheets guiding that link to each other, enter respectively in two smoke chambers, the evaporator section of two groups of heat pipe bundles in being provided in a side of two smoke-boxes is heated, heat-transfer working medium in it absorbs heat of vaporization becomes steam state, and the eminence that moves to heat pipe promptly is arranged in the condensation segment of two cold dielectric chambers of smoke chamber both sides, the condensation segment of these two groups of heat pipes respectively with separately independently two kinds of cold media in two cold dielectric chambers carry out exchange heat, when cold medium temperature raises, heat-transfer working medium in the heat pipe discharges behind the heat temperature and descends and be condensed into liquid and flow to evaporator section naturally along the pipeline that tilts, and carries out next circulation then.

The utility model compared with prior art has following advantage:

1, the utility model can utilize the two kinds of cold media of high-temperature flue gas preheating simultaneously in the same flue, makes equipment become one by two, has reduced almost half equipment cost.

2, the shared exhaust gases passes of the utility model, compact conformation, take up room little, bring big flexibility to technological design and site operation, be suitable for the restricted occasion of installing space, also created good condition for the optimization of the comprehensive utilization of heat energy and heat energy utilization.

3, the inefficacy of the utility model unit heat pipe does not influence the normal operation of other unit heat pipes, and is little to the influence of whole heat exchange effect simultaneously yet.
