The embodiment of dregs of a decoction steam multitube stoving process of the present invention, comprising the following steps: can refer to Fig. 1 to Fig. 5.
(1), the jet chimney 19 of roller drying machine discharge end side is opened, high-temperature steam enters rolling by jet chimney 19
Roller drier is preheated in steam multitube in cylinder drier, steam multitube includes air inlet pipe 14 and exhaust pipe 15 two
Point, steam multitube rotates together with roller.Specifically, air inlet of the high-temperature steam first by jet chimney 19 through rotary joint 13
131 enter in inlet box 16, enter back into the air inlet pipe 14 being connected with inlet box 16, preheat to roller drying machine.
(2), the dregs of a decoction (water content about 80%~90%) (water content about 40%~60%) after dewaterer mechanical dehumidification, falls
Enter onto belt conveyor 3.
(3) dregs of a decoction after preliminary hydro-extraction deliver into charger through belt conveyor 3, by charger through feed end 8
It is sent into roller drying machine.
(4), the dregs of a decoction are rotationally advancing in the roller of roller drying machine with roller, while being contacted with air inlet pipe 14, into
The high-temperature steam of tracheae 14 and dregs of a decoction heat exchange carry out heating, drying to the dregs of a decoction, and the steam after cooling is discharged by exhaust pipe 15.
High-temperature steam in air inlet pipe 14 with, because temperature reduces, some vapor can condense into droplet, these droplets after dregs of a decoction heat exchange
Fumer 17 can be entered with exhaust pipe 15, be discharged after rotary joint 13 by drainage pipeline 18.
(5), the dregs of a decoction after drying move to the discharge end of roller, and most of dregs of a decoction are fallen into out due to self weight by discharge port
In material machine 7, exported after further being broken up stirring in discharging machine 7.Small part swims in the dregs of a decoction in hot wind, then is removed by whirlwind
Dirt device 6 traps, and is also fallen into discharging machine 7 after dedusting, exports after further being broken up stirring in discharging machine 7.Contain
There is the tail gas of dust to be then discharged by the air outlet of cyclone dust collectors by air-introduced machine 5.
Above-mentioned stoving process can be implemented by the drying equipment of dregs of a decoction steam multitube drying equipment embodiment of the present invention, but not
It is confined to the equipment.
Stoving process of the invention has following characteristics:
(1) high production efficiency.It is compared with traditional intermittence type drying apparatus, which uses the drying work of roller frame
Skill reduces human input, greatly improves yield, it can be achieved that continuous continual production in 24 hours.
(2) device structure layout is succinct, reasonable.Firstly, roller drying machine tilts installation according to certain gradient.The dregs of a decoction with
Barrel body rotation the dregs of a decoction are discharged more easily, the dregs of a decoction stopped in roller as less as possible from high-end mobile to low side
Amount；Secondly, discharge end inlet and outlet of the high-temperature steam by roller；High-temperature steam is entered by low side, with the dregs of a decoction at counter current contacting.
Contact of the dregs of a decoction with heat source is more abundant, shortens drying time.
(3) product quality is easy to guarantee.The method that traditional dregs of a decoction stoving process uses flue gas directly to contact drying, can not
Pollution is generated to the dregs of a decoction with avoiding；And the present invention is equipped with steam multitube in roller, forms steam multitube drying machine.The dregs of a decoction and dry
Dry medium mediate contact avoids secondary pollution of the dried medium to the dregs of a decoction.
(4) thermal efficiency of roller drying machine is high.The thermal efficiency of steam multitube drying machine is mainly reflected on exhaust flow, with
Direct drying machine is compared, and the exhaust flow of steam multitube drying machine is small, thus the thermal energy taken away is seldom.It is, in general, that reaching
To identical dry mass, thermal energy needed for steam multitube drying machine is the 1/2~1/3 of direct dryer, and as the dregs of a decoction are wet
The advantage of the reduction of degree, steam multitube drying machine can dramatically increase.In addition, drainage pipeline 18 steams recycle heat exchange with can be convenient after
The condensed water that vapour is formed, improves the utilization rate of thermal energy.
(5) drying course is easy to control.Jet chimney and drainage pipeline are all independent systems, in respective pipe-line system
Be equipped with the devices such as corresponding thermometer, filter, pressure reducing valve, can according to the actual needs of production and to the temperature of steam,
Pressure and flow velocity etc. carry out necessary adjusting, convenience and high-efficiency in due course.
(6) drying course environmental protection.During the drying process, it because the exhaust flow of generation is small, is not easy to carry dust secretly；Simultaneously because
Containing compared with juicy in exhaust, be conducive to the recycling of waste heat in some special solvents and tail gas.In production process substantially without
Flue gas emission reaches exhaust gas evacuation standard, not can cause environmental pollution.
The present invention is not limited to above-mentioned preferred forms, anyone can show that other are various under the inspiration of the present invention
The product of form, however, make any variation in its shape or structure, it is all that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
