Abstract

The present invention relates to an oven-drying machine for drying formed carbon stick in artificial charcoal industry. Its structure includes air intake pipe, dry oven and its exhaust pipe, the outlet of said exhaust pipe is connected with an induced draught fan, the delivery pipe of said induced draught fan is connected with a closed tank, on the tank wall of said closed tank several through holes are set, in which the portion of said through holes is connected with a feed water header by means of water intake pipe, on the feed water header a water inlet is set, another portion of said through holes is connected with a water tank by means of drain pipe, the water outlet of the drain pipe is extended into the water body of said water tank. The hot air discharged by said invention is undergone the processes of filtration, adsorption, dissolving, cooling and precipitation of water body so as to obtain the purification, after having been cooled the wood tar is precipitated in the water bottom, can be recovered, and can be used as chemical dyestuff.

Description

A kind of dryer

Technical field

The present invention relates to a kind of drying plant, especially belong to a kind of dryer that is used for the drying forming carbon rod in artificial charcoal's industry.

Background technology

The operation principle of dryer is to be the thermal source medium with the hot dry wind, and waits to dry by the fire after the material heat exchange dry by the baking material, last in the baking oven, and hot blast carrying flue gas secretly, dry by the fire associated gas that material distributes and dust granules etc. arranges to atmosphere from the exhaust duct of dryer.Draw the problem of two aspects thus, the one, direct discharging meeting atmosphere pollution, the 2nd, contain the material of recyclable utilization in the emission.

At present, just there is such problem in artificial charcoal's industry.Its drying plant generally adopts airflow dryer, fluidized bed dryer or revolving drum drier etc., and still, this class machinery all has similar characteristics: all directly arrange to atmosphere without exception from the hot blast that the dryer exhaust duct comes out.At this moment, will carry volume of smoke secretly in the discharging hot blast, often contain a large amount of wood tar, dust and pernicious gas in the flue dust, not only contaminated air also causes corresponding waste, because wood tar can be used as chemical dyestuff after reclaiming.

Summary of the invention

For solving the problems referred to above that prior art exists, the present invention aims to provide a kind of dryer with novel structure, the hot blast that this dryer comes out from its exhaust duct is arranged when atmosphere, not only wherein dust granules, pernicious gas reduce in a large number, and utility for example wood tar can also obtain recycling.

For achieving the above object, the present invention has adopted following technical scheme:

A kind of dryer, comprise blast pipe, baking oven and exhaust duct thereof, and one and the air-introduced machine that links of said exhaust pipe outlet, the enclosed case that joins with the ajutage of air-introduced machine, be provided with several through holes on the tank wall of enclosed case, partial through holes wherein communicates with a water-inlet header through water inlet pipe, water-inlet header is provided with water inlet, another part through hole communicates with a water tank through outlet pipe, the delivery port of outlet pipe extends in the water tank water body, it is characterized in that: the enclosed case is formed through the pipeline serial connection by some pillar buoys, and the pipe diameter that is used to be connected in series is less than the barrel dliameter of pillar buoy.

The mouth of pipe of the water inlet pipe of enclosed case is provided with water atomization plant.

The degree of depth that the delivery port of enclosed case outlet pipe extends the water tank water body is 40-50 centimetre, and the degree of depth of water tank water body is 100-150 centimetre.

Beneficial effect: the present invention is provided with emission-control equipment by the outlet at the dryer exhaust duct, original directly row is caused in the water body to the hot blast of atmosphere, cause the flue gas, dust granules and the related substances that contain in the hot blast through effects such as the filtration of water body, absorption, dissolving, cooling precipitations, not only reduced pollution, also can effectively reclaim wood tar as chemical dyestuff to atmosphere.

Description of drawings

Accompanying drawing is an overall structure floor map of the present invention.

The specific embodiment

Referring to accompanying drawing, sequence number is represented respectively among the figure: baking oven 1, exhaust duct 2, water-inlet header 3, water inlet pipe 4, water inlet 5, enclosed case 6, water body 7, water tank 8, outlet pipe 9, air-introduced machine 10, blast pipe 11, ajutage 12, pipeline 13.

The structure of dryer is not done any change among the embodiment, therefore, has only done schematic expression in the drawings, comprises blast pipe, baking oven and exhaust duct thereof.100-150 ℃ hot dry wind flows after blast pipe 11 is sent into baking oven 1 from the below of baking oven 1 from lower to upper, carry out heat exchange with the moulding carbon rod on the baking bed, at last, cause the hot blast treating apparatus at air-introduced machine 10 rear portions from exhaust duct 2 under the effect of air-introduced machine 10, the hot blast temperature of this moment has dropped to about 40-50 ℃.

Ajutage 12 is sent into hot blast in the enclosed case 6.Enclosed case 6 is the casing of a hollow tube-shape, has drawn two among the figure, and two enclosed casees 6 are by pipeline 13 serial connections, and the diameter of this pipeline 13 to play depressurization, slows down the hot blast flow velocity less than the barrel dliameter of enclosed case 6.Quantity as for enclosed case 6 is The more the better from effect, and its shape can be varied certainly.

Some through holes are set on the tank wall of enclosed case 6, and partial through holes communicates with the water-inlet header 3 at top through water inlet pipe 4, establishes water inlet 5 on the water-inlet header 3 and joins with running water pipe.Another part through hole communicates with a water tank 8 through outlet pipe 9, and the delivery port of outlet pipe 9 stretches in the water body 7 in the water tank 8.The degree of depth that delivery port stretches in the water body 7 is advisable with 40-50 centimetre, and the degree of depth of water body 7 is 100-150 centimetre in the water tank 8.

During concrete enforcement, the mouth of pipe of the water inlet pipe 4 of enclosed case 6 is provided with water atomization plant, and this device can adopt the structure of sprinkle nozzle, makes the water atomization that enters enclosed case 6.

For further deepening the impression, below the applicant will make a presentation again its course of work in conjunction with the accompanying drawings.After the ajutage 12 of air-introduced machine 10 is sent into hot blast in the enclosed case 6, at first be subjected to the spray of atomized water, then, the delivery port through outlet pipe 9 drains in the water body 7 again.Hot blast is purified through effects such as the filtration of water body 7, absorption, dissolving, cooling precipitations, arranges to atmosphere after water body 7 comes out again, thereby has reduced pollution to atmosphere, and wood tar cooling postprecipitation is in water, and recovery promptly can be used as chemical dyestuff.

Water tank 8 can adopt open type water tank type structure, and big I is decided according to actual conditions.Certainly, water tank 8 also can adopt adds a cover closedly, and the air-flow that will come out from water body with pipeline is concentrated and guided airborne release into again.
