Abstract

A dryer for drying and molding carbon rod in artificial charcoal industry consists of a blast pipe and a drying oven with an exhaustion pipe, wherein, the outlet of the exhaustion pipe is connected with an induced draught fan having a blast tube communicated with a closed type box; the wall of the closed type box is provided with a plurality of through holes with part of the through holes communicated with a feed-water header having a water intake through an admitting pipe and the other part of the through holes with a water tank through a rising pipe having an outlet extending into the water body inside the water tank; the nozzle of the admitting pipe of the closed type box is disposed with a water atomization device; the closed type box is formed by a plurality of column-shaped drums connected in series through a pipeline with the diameter being less than that of the column-shaped drums. The utility model has the advantages of that: the released hot blast is purified through treatments such as water body filtration, absorption, dissolution, cooling and deposition, thereby reducing air pollution; in addition, wood tar deposits under water after being cooled down and can be reclaimed for being used as chemical dyes.

Description

A kind of dryer

Technical field

The utility model relates to a kind of drying plant, especially belongs 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 utility model 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 utility model has adopted following technical scheme:

A kind of dryer, comprise blast pipe, baking oven and exhaust duct thereof, it is characterized in that: further comprising an air-introduced machine that links with said exhaust pipe outlet, and 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, and water-inlet header is provided with water inlet, another part through hole communicates with a water tank through outlet pipe, and the delivery port of outlet pipe extends in the water tank water body.

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

Described 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 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 utility model 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 the utility model overall structure floor map.

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 water, 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.
