Description
Technical field
The present invention relates to a kind of high-temperature solid bulk cargo waste-heat recovery device, more particularly to a kind of particle size and shape on a large scale
Efficient pair of hot trap solid granule waste-heat recovery device of the high-temperature solid bulk cargo of state.
Background technology
Industrial processes can usually produce big amount temperature and be up to hundreds of degrees Celsius, or even thousands of degrees Celsius of high-temp solid
The molecular sieve catalyst after blast furnace solid impurity particle, high-temperature metallurgy slag particles, roasting after bulk cargo, such as dry granulation, come out of the stove after chemistry
Product etc..The residual heat resources of these high-temperature solid bulk cargos and the high-temperature flue gas supervened are recycled, industrial energy saving are reduced discharging,
Efficiency of energy utilization is improved, there is vital effect.There are three classes for this available technical concept:(1) direct heat transfer；Typically
By empty gas and water and conduction oil etc. as heat transferring medium, heat exchange is realized by medium-solid directly contact.The method is imitated
Rate is high but cannot ensure that heat transferring medium is cleaned；(2) indirect heat exchange；Heat transferring medium takes heat by partition from high temperature bulk material, it is to avoid with
Solid granule directly contact, it is ensured that pollution-free；(3) radiant heat transfer：Heat exchange is changed into using solid granule to emission radiation energy
The heat energy of medium with realize heat transfer.
Because direct heat transfer is difficult to obtain cleaning medium, radiant heat transfer is difficult by equipment and effectively realizes.Research at present is inclined
To in indirect heat exchange, by strengthening septate heat transfer device waste heat high efficiente callback is realized.But septate heat transfer device is in commercial Application
In there is also certain limitation --- the particle size range that can be used for the granule of waste heat recovery is too small, have ignored the excellent of direct heat transfer
Gesture, excessive power set cause additional energy, the Modulatory character of equipment poor etc..Additionally, being often related to have in process industrial
Multistage cooling, heating and energy exchange unit, improperly designing can cause a large amount of industrial exhaust heats of procedures system generation, and these
Waste heat is often seldom reused, so as to cause process high energy consumption, low production efficiency, product competitiveness poor.Produce these problems
Basic reason be that single equipment or single process of the design process often only to system local is optimized, lack consider it is many
Yardstick different aspects total system it is energy-optimised integrated.
The content of the invention
It is an object of the invention to provide it is a kind of can abundant recovery waste heat resource waste-heat recovery device.The present invention passes through spiral shell
Bar conveying equipment, using medium and going hot mode to realize that many sides rapidly and efficiently take heat with cleaning, is adapted to granule chi on a large scale
The high-temperature solid bulk cargo of very little and form.Technical scheme is as follows：
A kind of efficient pair of hot trap solid granule waste-heat recovery device, including cylinder 1, the screw rod 3 with screw cavity 5, its
In,
One end of cylinder 1 offers the feeding mouth for accepting the solid high-temperature bulk cargo that industrial furnace or reactor are discharged, and
Offer air outlet slit；Other end lower section offers solid granule discharging opening, and this end top offers air intlet；It is empty in screw rod
The inwall in chamber 5 is provided with spiral rifling 6；
While screw rod 3 is rotated, the heat transferring medium of circulation is changed indirectly with reverse high-temperature solid bulk cargo in screw cavity 5
Heat, gives screw rod 3 equidirectional rotating speed as the fluid forces spiral rifling 6 of heat transferring medium；
The air preheated through industrial furnace or reactor or the oxygen rich gas comprising last time cycle gas pass through air intlet
Into after cylinder, Jing air outlet slits after heat are taken combustion-supporting into industrial furnace or reactor.
The technique effect of the present invention is as follows：
1. medium and heat exchange mode realize that efficiently quick and cleaning takes heat for many sides：Air enters cylinder through radiant heating
It is interior inversely to change indirectly with the reverse direct contact heat transfer of high-temperature solid bulk cargo, heat transferring medium (empty gas and water etc.) and high-temperature solid bulk cargo
Heat.
2. the raising of heat exchange efficiency and device controllability：The screw-rod structure of rotation improves the turbulence effect of high-temperature solid bulk cargo
Fruit and heat and property, in direct heat transfer ensure that contact is abundant, ensure to take heat in indirect heat exchange abundant；By screw speed
With the control of heat transferring medium flow velocity, the controllability of waste-heat recovery device is improve.
3. the high closeness of whole heat-exchanger rig, reduces the discharge of waste gas：The generation and flowing of whole waste gas only occurs
In residual neat recovering system.
4. the practicality of screw rod increased the scope of application of this waste-heat recovery device：It is adapted to particle size and form on a large scale
High-temperature solid bulk cargo.
5. screw cavity inwall sets spiral rifling, can be rotated with boosting screw rod, saves energy.

Wherein：1- cylinders, 2- screw conveying devices, 3- screw rods, 4- flights, 5- screw cavities, 6- spiral riflings, 7- combustions
Material stove (industrial furnace or reactor)
Specific embodiment：
Below in conjunction with the accompanying drawings the present invention will be further described in detail：
As shown in Figure 1：High-temperature solid bulk cargo is entered in cylinder 1, is moved to solid packing exit with the rotation of screw rod 3,
In the process, after the burning radiation heating of fuel air or oxygen rich gas (including last time cycle gas) passes through sky
Gas import enters cylinder 1, with the reverse direct contact heat transfer of solid high-temperature bulk cargo, takes the air after heat and is entered by air outlet slit and fire
Material stove 7 is combustion-supporting；While screw rod 3 is rotated, the heat transferring medium (empty gas and water etc.) of circulation is solid with reverse high temperature in screw cavity 5
Body bulk cargo indirect heat exchange, takes the heat transferring medium after heat and can be used to other purposes；Above procedure occurs in the system of closing, greatly
Amount reduces the discharge of waste gas (cigarette).The spiral rifling 6 with certain steering that screw cavity inwall is present, it is ensured that be situated between as heat exchange
The fluid forces spiral rifling of matter gives screw rod equidirectional rotating speed, reaches the purpose of the rotation of boosting screw rod 3, saves energy.Screw rod 6
