Abstract

The utility model provides an indirect dryer special for rotary drum type garbage processing for drying organic fertilizers. Flue gas enters from a smoke inlet pipe after air distribution and thermoregulation, then is distributed in an external smoke channel and an internal flue via a smoke branched pipe, and finally is collected via a smoke collection pipe and is output by the smoke outlet pipe. A spacer plate in the external smoke channel is used for separating the external smoke channel, which increases the velocity of flow gas and prevents deposition, meanwhile, bringing convenient to process and manufacture; the spacer plate and a tube structure commonly stress, which raises the stiffness of the drier. The flue gas seals arranged on the smoke inlet and outlet pipes replace the old seal arranged on a cylinder. On the job, the dryer uniformly rotates while material enters a drying chamber from a fork feed pipe on the tip end of the dryer; a heat radiation frying plate and a cooling plate transform heat energy to the material at the process that the material is endlessly fried up, blocked, and fell down; the material is moved to the tail end because of the installation angle of the dryer and gravitational effect; the material which is dried is exhausted from a discharge port. An air inlet is used for delivering normal temperature air to the drying chamber, which ensures a gas-pressure balance in the drying chamber; exhaust gas is output by an air guide port.

Description

The special-purpose indirect dryer of rotation drum type garbage disposal

Affiliated technical field

The utility model relates to the drier that uses when a kind of organic compost that is exclusively used in the production of producing fertilizer from refuse in daily life treatment process carries out deep processing.

Background technology

It is comparatively ripe that China is used for the dry technology of industrial powder, particle, block and fluid of industries such as metallurgy, building materials, chemical industry, food, medicine, and the phase formula is arranged its drying equipment and belt dryer, sulfuration bed dryer, pneumatic conveyer dryer, spray dryer, drum dryer and turning circle cartridge type are straight, indirect dryer and high-frequency dryer and microwave dryer etc.Because various driers all have its material application scope, and the material properties difference of every profession and trade, therefore required drier all has very strong specific aim.The dry general flue gas that produces with the incinerator of the oversize of burning away the refuse of organic compost is a thermal source, and owing to have differential very big, the unit weight difference is very big and moisture content is higher characteristics between the organic compost particle, on the drier type, only turning circle cartridge type drier is applicable to the drying of organic compost, and, cause existing turning circle cartridge type indirect dryer to be not suitable for the drying of organic compost because flight structure, flue gas type of flow in drier of turning circle cartridge type indirect dryer make it be restricted in the use of organic compost drying.So the garbage disposal industry is used for the turning circle cartridge type convection drying device that the equipment of organic compost drying all is employing metallurgy, building materials, chemical industry use at present.But its is that flue gas that incinerator produces directly contacts pollution organic composts such as the organic gas that can make flue gas and heavy metal with organic compost being used for shortcoming one that organic compost exposes when dry, influences product quality; The 2nd, when the waste gas that dry run produces was discharged with flue gas, the fine particle in the organic compost also can be taken away by flue gas, and this has not only increased the burden of dust removal installation, has also increased the flue gas intractability; The 3rd, the variation of the start of drier, shutdown operation and material water ratio has a strong impact on the pressure balance of incinerator system in the dry run, thereby causes the furnace temperature fluctuation of incinerator even cause blowing out, causes environmental pollution and economic loss.

Summary of the invention

In order to solve the problem that the organic compost dry run exists, the utility model has adopted a kind of rotation drum type indirect dryer of new structure, the turning circle cartridge type indirect dryer that has overcome other industry is used for the restriction of organic compost drying, also preferably resolve the problem that exists when turning circle cartridge type convection drying device is used for the organic compost drying, and because outer cylinder body has adopted the regular polygon structure to make processing and fabricating more convenient.

The technical scheme that its technical problem that solves the utility model adopts is: high-temperature flue gas is entered by the smoke-intake pipe of drier head end after the temperature that air distribution obtains suiting, by smoke separating pipe with smoke distribution in the external flue and internal flue formed by regular polygon outer cylinder body and circular inner tube body and dividing plate, the internal flue outlet diameter dwindles, being beneficial to flue gas distributes to external flue, through smoke collection pipe flue gas is come together in the pipe identical with the smoke-intake pipe diameter afterwards and draw, enter flue gas treating process.The dividing plate of external flue is used for preventing the resistance that the flue gas turbulent flow brings and increases the flow velocity of flue gas in external flue preventing that dust is deposited in the external flue inner product in the flue gas.The turnover smoke pipe sealing of drier all is installed in outside the cylindrical shell, has reduced sealing area and sealing difficulty, increased the stability of drier operation.Organic compost enters hothouse from the forked type feed pipe of drier head end, and the heat radiation flight that is located at the inner barrel inboard is constantly taken up organic compost, fall in the cylindrical shell rotation process, simultaneously thermal energy transfer is played desiccation to material.The heat sink that is located at the internal flue outer wall also can block the material that falls after part is taken up by the flight that dispels the heat, and carrying out once more, heat transmission increases drying effect.The regular polygon outer cylinder body contacts with external circular steel band with carrying, driving and sealing and swathes.Driving mechanism makes drier by the design direction uniform rotation by the gear ring effect under the duty.Material moves to the drier tail end from the drier head end because of the influence of gravity effect and setting angle, and dried material is discharged from the discharging opening of drier tail end.The air inlet of feed end is used for to sending into normal temperature air in the hothouse guaranteeing the air pressure balance in the hothouse, also can send into air after the heat exchanger heating thus for improving dryer output.The waste gas that produces in the hothouse in the dry run is drawn by the air-vent of drier tail end and is handled.

The effect that the utility model is useful is: the organic compost contact drying, and flue gas was to the pollution of material when material and flue gas had separately been avoided convection drying; Avoided the particle in the material to be taken away the efficient that influences dust pelletizing system by flue gas; Avoided that drier leaves, in the stopping process and material moisture influence the CIU pressure balance when changing; This indirect dryer has used the flight structure of convection drying device simultaneously, avoided material and drier inwall and flight bonding to influence drying effect, improved the flow regime of flue gas in drier, prevented in the flue gas dust accumulating in the inside and outside flue of drier, both solved existing indirect dryer because of flight structure and flue structure defective are not suitable for the problem of organic compost drying, and solved the convection drying device again and be used for the problem that organic compost exists when dry.
