Description
A kind of multiple technologies scheme of energy-conservation dryer relates in particular to the multiple technical schemes of energy-saving industrial cloths dryer that specialty washing factory uses.
The energy consumption of employed industrial drying machines such as the shop of the washing of the specialty in hotel, hotel and society at present, specialty washing factory is all very big, and especially the energy consumption of the employed large quantities of dryers of the specialty big factory of washing is surprisingly big especially! A large amount of waste heats is discharged to place in vain, has not only wasted the energy and capital, but also has polluted environment! In order to solve energy-saving and emission-reduction, reduce cost, problems such as protection environment, I have invented multiple multiple technical schemes of energy-saving industrial cloths dryer.
In order to implement the energy-conservation purpose of industrial drying machine, it is as follows to the present invention proposes multiple embodiments:
One, the separated heat pipe thermal energy recoverer energy-saving scheme that combines with the general industry dryer and use.
Because general general industry dryer all is not energy-conservation, main cause is that industrial drying machine is when drying, once the hot gas of also underusing is drained, caused energy waste, in order to reduce the waste of heat energy, the best way is exactly that recovery waste heat utilizes again, for reaching this purpose, people have invented the heat pipe waste-heat recoverer, use beyond example still but really the heat pipe waste-heat recoverer is used in to combine on the industrial drying machine, the precedent that especially adopts separated heat pipe thermal energy recoverer and general industry dryer to be used in combination is not more seen.In order to realize energy-conservation purpose, the present invention has adopted such scheme.The assembled scheme of so-called separated heat pipe waste-heat recoverer and industrial drying machine is: in the bottom of industrial drying machine, the dryer of middle-size and small-size (75-200 pound) air exhauster is on the room of its exhausting duct front end, hypomere heat pipe comb case (heat pipe comb case can be selected for use refrigerant condenser to change series connection and use for back in parallel is communicated with, and also can directly add inside and outside fin with heat-transfer pipe and assemble) is installed.Install (section) heat pipe case on the top of industrial drying machine heat exchanger next door, two tanks is connected with the copper pipe that is suitable for mutually up and down then, after integral body finds time to fill working medium then, forms a split type waste-heat recoverer.Its operation principle is: after the industrial drying machine starting, be full of vapours or electronic box on the top in the heat exchanger and begun heating.Because the draft effect of the exhaust blower of dryer bottom, two sides, the side air of heat exchanger on the top, be drawn through the heat-exchanger fin comb and absorb the heat energy intensification, enter then in the machine by rotating the clothes layer of upset, clothing is heated, and the damp and hot waste gas that is evaporated to aqueous vapor is taken away outside the discharge machine in the lump.After airflow duct was introduced the damp-heat air of discharging separated heat pipe waste-heat recoverer hypomere comb case and passed through, in line to go into atmosphere aerial.Because when damp-heat air passes through hypomere comb case, finned tube is heated, heat transfer medium in the pipe is heated simultaneously and is evaporated to gas, enter separated heat pipe epimere comb case along connecting heat pipe toward rising, meet and emit heat energy and cooling after cold and become liquid and wander hypomere, the cold air that flows through outside epimere fin comb case siphons away heat energy in other words, cause air flowing to be heated intensification, the cooling of the temperature of hot gaseous medium in pipe mistake simultaneously becomes liquid and wanders hypomere again, absorbs heat energy once more, repeats aforesaid process, thus and thus, Zhou Erfu rises, and dryer is just constantly obtained preheated air, thereby the consumption that has reduced the energy realizes purpose of energy saving.
Two, integrated thermal waste-heat recoverer and dryer combination energy-saving scheme:
Transform energy-conservation dryer as for the ease of existing industrial drying machine, can adopt the integrated thermal waste-heat recoverer to be loaded on dryer rear exhaust port place.Its operation principle is after allowing hypomere heating, the heat pipe hypomere of waste hot gas by the heat pipe recover be heated, and the vaporization of can absorbing heat of the medium in the pipe rises to epimere.Heat pipe case epimere just can heat up, and the cold air of epimere process can absorb heat energy and be rapidly heated, and simultaneously, is cooled to liquid and wanders hypomere after the steam heat release in the pipe.Air after the intensification is delivered to the air inlet that heat exchanger is gone up on the dryer top by conduit, be inhaled into heat exchanger then, after further heating, directly enter suction drying in the dryer, the damp-heat that produces is finally again outside exhaust outlet discharge machine, enter section under the integrated thermal waste-heat recoverer then again, repeat aforesaid process again, thus and thus, Zhou Erfu rises, dryer just can obtain pre-warmed heated dry air continuously and help drying, thereby has reduced the consumption of thermal source, reaches purpose of energy saving.
Three, the dryer energy-saving scheme that combines with multistage outer fin comb case:
Because the manufacturing technology and the cost requirement of preceding two kinds of heat pipe waste-heat recoverers are all higher, though it is handy, energy-saving effect is also fine, but in order to save cost, simultaneously can reach purpose of energy saving again, the present invention adopts dryer and multistage outer fin comb case combination energy-saving mode, and specific embodiments is such.Industrial drying machine behind exhaust outlet a multistage inside and outside fin comb case is installed, the air inlet sealing that the outlet of case face adopts wireway and dryer top to go up heat exchanger is connected leads to, perhaps the next door of the heat exchanger on the top of industrial drying machine; One or both sides are installed all adorn the above outer fin comb casees of a secondary or three grades (annotating and adopt the existing condenser transformation of the way, is one-level in each rice of flow process).With air conduit multistage outer fin or the air inlet of the inside and outside exhaust bobbin carriage that fin all arranged and the exhaust outlet of industrial drying machine are connected then.In the exhaust ports of multistage fin comb case a power-assisted air exhauster is installed again then, even if so new energy-saving industrial dryer successful installation.Its operation principle is: so-called multistage fin comb case is actual to be exactly a gas one gas formula air heat exchanger.After the industrial drying machine starting, the damp-heat air that its exhaust outlet is discharged enters when one-level one-level ground flows through in the comb of multistage fin comb case, fin comb heat temperature raising wherein, yet at one time, the cold air that the comb outside of multistage fin comb case is flow through also constantly spreads out of next heat energy in the absorption tube, heating up gradually becomes preheated air, and the heat exchanger that enters dryer is accepted further heating, and enters the water content in the heating evaporation clothing in the dryer.Because dryer is constantly obtained the preheated air of multistage fin comb case produced (30-50 degree temperature is arranged approximately), therefore reduced the consumption of electric energy or steam heat energy, finally realize the target of energy savings.
Four, industrial drying machine knot platform automatic control switch valve or air exhauster use energy-saving scheme:
To power-economizing method and embodiment, people's requirement is more and more higher, not only requires energy-conservation manyly, and requires that energy-saving equipment is simple, practical, cost is low, easy to operate again more wants attractive and durable easy-maintaining.Now introducing the 4th kind of scheme is one of them.So-called dryer uses energy-saving scheme in conjunction with automatic switch valve or air exhauster, a kind ofly really compete energy-conservation economical and practical again good scheme, its structure is by electronic box automatic valve of control or an automatic wind exhaust machine, be installed on the industrial drying machine exhaust outlet behind, and form with the closed connection of the heat exchanger air inlet at wireway and dryer top.Its operation principle is: when industrial drying machine is started working, waste hot gas endlessly just can be discharged in its back, yet this waste hot gas is the disposable clothing layer that passes in the machine, and in fact its heat and water absorbing capacity are not utilized fully, have just been wasted outward by the exhaust blower shedder.I have designed automatic reflux valve door pipeline owing to this reason, the waste hot gas of discharging in the machine is blocked back the dryer heat exchanger to be reheated, again utilize, after waiting to recycle a period of time, treat that drying built-in temperature speed rises to about 80 ℃-120 ℃, drain tap is opened automatically, damp-heat air in the machine just can be discharged fast, when waiting to reach the scheduled time, valve can be closed again automatically, repeats aforementioned process.Thus and thus, Zhou Erfu rises, because waste hot gas is fully used, thereby has reduced the thermal energy consumption of industrial drying machine, has finally reached purpose of energy saving.In addition, can not want automatic valve yet, replace with the air exhauster of a same model.But air exhauster must install an one-way cock additional at exhaust outlet, controls air exhauster on schedule or temperature work with circuit control box.Can realize energy-conservation purpose too.
Five, the industrial drying machine energy-conservation drying scheme that combines with heat pump and use:
Aforementioned four kinds of energy-conservation dryer schemes all are to reclaim the power-economizing method of heat energy.Now the 5th kind of energy-conservation drying scheme of Jie Shaoing is that concrete structure is based on the up-to-date methods of the generation drying energy: the heat exchanger at existing common dryer top is dismantled not! Other adorns and utilizes hot-air that heat pump discharges and cold dry air as energy drying clothes suitable (100 pounds dryer is joined six to ten heat pumps).Concrete operation principle is: so-called cold and hot unit heat pump: also be refrigeration unit, air-conditioner or be title such as air dryer.Since the cold and hot air made of heat pump all have can drying clothes performance, and both can singly supply with the dryer use with also merging together, promptly so-called low temperature drying agent just is meant the cold dry air that heat pump is made and the mixing air of hot-air.After the heat pump starting, what discharged by radiator is 40-60 ℃ hot-air, and what discharged by condenser is 10-16 ℃ the cold dry air that has removed moisture content, after these two kinds of hot cold airs are sucked by dryer, can absorb the water content in the clothing body when passing the clothing layer soon, be equivalent to the drying ability of 80 ℃ of hot-airs.But its power consumption generates heat than direct electricity consumption and adds the hot-air drying and compare, again could using electricity wisely how three times! All more far better than above-mentioned any power-economizing method energy-saving effect! But comparatively speaking its manufacturing technology, safeguard uses, manufacturing cost etc. also all than above-mentioned several energy-saving schemes requirements from!
Six, combined burning stove and heat exchange of heat pipe combination dryer energy-saving scheme.
In order fundamentally to reduce cost, with energy savings except adopt the waste heat recovery scheme energy-conservation, adopt the combined burning stove to combine again and produce the energy-saving scheme that thermal source uses for dryer with heat exchange of heat pipe, start unit heat supply new model, work along both lines and reduce energy resource consumption, its structure and operation principle are as follows: generally washing factory all is to adopt the combined heat mode, use for tens steam as one or more large-sized boiler to hundreds of platform dryer, this heat supply mode is of great benefit to large-scale production, cost is lower, particularly production scale is little but to miniaturization laundry, the little factory that business is flat wants starting large steam boiler or purchase large-sized boiler steam supply just not to conform to and lets it pass.Calculate cost just less than unit heat supply calculated.The combined burning stove is the energy-conserving and environment-protective gasification burner of available diversified economy fuel heat supply.Add that heat exchange of heat pipe cooperates heat supply gas to use compared with using electrical heating to industrial drying machine, or more than the cost of Boiler Steam heat supply will hang down three one-tenth.Why? output less again must be big with the starting loss of cauldron air feed sometimes because heat supply distance heat-energy losses is how! Starting time is long, loses time to equal to lose money! Therefore integrate just many not as single stove unit heat supply advantage.Concrete structure is: the bottom is a pluralities of fuel vaporization combustion stove, top is fin heat pipe comb case, fin comb case heat exchanger divides open and closed two kinds, open comb case divides two kinds of through type and turning multi-stags again, no matter that is a kind of, its heat exchange form all is to flow from the bottom up in the stove fire feeding comb, in flowing, give fin outside the pipe thermal energy transfer, after giving heating the outer cold air then of the comb of flowing through then, by industrial drying machine by communicating pipe hot gas suction dryer drying clothes.Closed comb case has another name called heat pipe comb case, and what its operation principle was different with the former is, stove fire does not directly feed in the comb, and just as enamelware pot, the pyrotechnics waste heat is drained from another smoke exhaust pipe.Advantage is an easy clean surface dust stratification carbon distribution, and the heat transfer heat exchange efficiency is than open comb height.Have the each side advantage because comprehensive combination stove heat exchanger and dryer are used in combination, finally can realize energy-saving and emission-reduction, the purpose that reduces cost is that washing facility manufacturer should select the production product, also is the equipment that specialty washing factory should select!
