Abstract

An air-flow drying machine capable of recycling waste heat of tail gas comprises an air heat exchanger, a feeding system, a drying pipeline, cyclone separators, a discharging spiral conveyer and a tail gas pipeline. The air heat exchanger, the feeding system, the drying pipeline, the cyclone separators, the discharging spiral conveyer and the tail gas pipeline are sequentially connected. The tail gas pipeline passes through a fan and is connected with a waste heat recycling device. The waste heat recycling device comprises a shell and a waste heat exchanger arranged in the shell, wherein a tail gas inlet, a tail gas outlet, an air inlet and an air outlet are formed in the shell. A pipeline in the air outlet is connected with the air heat exchanger. The waste heat is utilized, waste is reduced, the waste heat recycling device is additionally arranged on the tail gas pipeline of the air-flow drying machine, the heat of the tail gas is utilized for heating air entering the drying machine, and dry air is preheated, so that steam consumption is reduced, the effects of energy conservation and emission reduction are achieved, and better economic benefits and environmental benefits are obtained.

Description

A kind of pneumatic drier can using waste heat from tail gas reclaiming
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of manufacture of pneumatic drier, relates in particular to a kind of pneumatic drier that carries out using waste heat from tail gas recovery.
Background technology
Pneumatic drier is under negative pressure state, utilization, after over-heat-exchanger heat exchange, reaches the high speed thermal current of 160 ℃ ~ 180 ℃ of left and right, makes the wet stock of the granular that disperseed, in drying tube, under suspended state, conduct heat, mass transfer, finally reach the object of dry powder; Powder enters airlock from cyclone separator and enters discharging spiral conveyor discharge again, and damp-heat is disposed to atmosphere by blower fan; The temperature of damp-heat air is at 54 ℃ ~ 65 ℃.The damp and hot vapour being disposed in atmosphere contains a large amount of calorific values, is directly disposed to the waste that atmosphere is not only a kind of heat energy, and surrounding environment is had to some impact, haves much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, provides a kind of and can effectively reclaim using waste heat from tail gas, saves the energy, the antipollution pneumatic drier can using waste heat from tail gas reclaiming.
Key problem in technology of the present utility model is to set up heat recovery device on exhaust pipe, utilizes the waste heat of tail gas to carry out preheating air, for follow-up dry processing, saves the energy, and using waste heat from tail gas is effectively reclaimed.Its concrete technical scheme is: a kind of pneumatic drier can using waste heat from tail gas reclaiming, comprise the air heat exchanger, feed system, drying pipeline, cyclone separator, discharging spiral conveyor and the tail gas pipeline that connect in turn, it is characterized in that tail gas pipeline passes through blower fan, pipeline connects waste-heat recovery device, described waste-heat recovery device comprises housing, is arranged at the residual-heat exchanger in housing, on housing, be provided with tail gas into and out of air port and air into and out of air port, described air air outlet pipeline connects air heat exchanger.
As further improvement of the utility model, described tail gas air inlet is provided with air cleaner.By this kind, the impurity in effective filtration tail gas is set, improves efficiency of heat exchanger and extend its service life.
As further improvement of the utility model, in the housing of described waste-heat recovery device, separately have additional purging system.
As further improvement of the utility model, described residual-heat exchanger is plate-fin heat exchanger.Using the dull and stereotyped and fin heat exchanger as heat transfer element.It mainly consists of plate bundle and end socket etc.Plate is intrafascicular some passages.Between two flat boards of every layer of passage, place fin, and seal with strip of paper used for sealing in both sides.Different according to fluid-flow mode, cold and hot fluid channel spacing is overlapped, also soldering one-tenth is whole in arrangement, i.e. manufactured Board bundle.Two fluid-flow modes have adverse current, cross-flow and wrong adverse current etc.A, B fluid import plate beam passage separately by entrance end socket through the flow deflector of a dispensing section respectively, then are directed at outlet end socket and draw through the flow deflector of another dispensing section, and two fluids are the heat exchange of adverse current partition.The forms such as that conventional fin has is straight, porous, sawtooth and ripple.Its advantage is: one, usefulness is high.Because of the disturbance of fin convection cell, the boundary layer that forms thermal resistance is constantly updated, heat transfer coefficient is generally 3 times of shell-and-tube heat exchanger; And under the little temperature difference (1.5~2 ℃), heat (cold) amount recovering effect is good.During for the heat exchange of gas-gas, effect is best.
Two, compactness.Because most of heat is to transmit by flat board through fin, the heat transfer area of FU volume can reach 1500 meters 2/ rice 3.
Three, lightweight.When heat transfer area is identical, weight is bordering on 1/5 of shell-and-tube heat exchanger.4. firm.Because plate Shu Weiyi single piece and fin play supporting role between two flat boards, therefore can bear higher operating pressure.In addition, also can in same equipment, realize multiple fluid heat exchange simultaneously.But plate-fin heat exchanger passage is narrow and small, easily obstruction, and cleaning maintenance is more difficult, and manufacturing process is more complicated.Its large multiplex aluminium alloy manufacture, also available copper, stainless steel and titanium etc.Due to aluminium, to have good cryogenic property, weight light again, therefore aluminum plate-fin heat exchanger is specially adapted to the profound hypothermia equipment such as oxygen, ethene and helium liquefaction, also can be used in power set.Aluminum plate-fin heat exchanger is generally used for design pressure, and to be less than 6.3 MPas, design temperature be the occasion of+200~-270 ℃.
The beneficial effects of the utility model: the utility model utilizes waste heat, cut the waste, on the exhaust pipe of pneumatic drier, increase heat recovery device, utilize the heat of tail gas to heat the air that enters drying machine, make dry air obtain preheating, thereby can reduce the consumption of steam, reach the effect of energy-saving and emission-reduction; Receive good economic benefit and environmental benefit.
