Abstract
A concurrent flow drying device for materials can be widely applied in the fields of chemical industry, coal, building materials and metallurgy, and is formed by a casing as well as a feed hopper, a discharge hopper, a hot airflow inlet, a hot airflow outlet, a flow guide block/strip and a flow guide plate which are mounted on the casing, wherein a heat insulation layer is wrapped around the casing. After being fed into the device, the materials to be dried are instantly exposed to the hot air flow fed from the hot airflow inlet, and conduct heat exchange in the regions provided with the flow guide block/strip, and then the moisture evaporates and the temperature of the air flow is reduced. Next, heat exchange is conducted continuously in the material waterfall position formed on the flow guide plate until the materials reach the standard of drying, and then the materials and the air flow leave the system from the bottom of the system. The whole device is in the negative pressure state. As the device adopts concurrent flow drying, the device is characterized by great output force, high efficiency, small pollution and low energy consumption. Furthermore, the concurrent flow drying device solves the problems that spontaneous combustion can be caused because small particles are too dry and the temperature of the discharged materials is too high.
Description
Technical field
The utility model relates to a kind of drying equipment of material, can be widely used in fields such as chemical industry, coal, building materials, metallurgy.
Background technology
Dry technology is divided into direct heating, indirect two classes on the mechanism of drying.And directly heating is divided into physical dryness and chemical modification two classes.
In the convection drying, at present mature technique is the rotary pipe type dry technology, but its energy consumption height, floor space are big, and because material contacts inhomogeneously with drying medium, usually can cause the problem of heat transfer.Because the restriction on the drying mechanism, the unit power output of such device are difficult to enlarge.Though adopt hot blast to improve the utilization ratio of heat energy greatly as the fluidized bed drying technology of drying medium, improved unit power output, but the energy consumption height, and the raw material granularity that enters drier is strict, otherwise can cause the problem of fluidisation control, limit the development of fluidized bed drying technology.
Contact drying mainly is to adopt low-pressure steam as thermal source, in fluid bed with the form indirect material of pipe laying.But the granularity of material has strict requirement equally, and the fluidisation energy consumption is not improved.
Processes such as other mechanical dehydration, hot pressing dehydration, HTHP dehydration, also very immature at present, be in laboratory stage.From drying medium, use to contain the high drying medium of oxygen, the situation in hot-spot issues the danger of being conigenous combustion easily.And use water vapour as drying medium, and need to overcome the gasification latent heat of water again, cause huge energy waste.
A kind of in the last few years vibrating mixed flow drying method has caused people's attention.This method is mainly material and sends into the vibrating mixed flow dryer system by the air-locked type batcher, and material carries out heat exchange and water evaporates with the thermal current that makes progress in the process that moves downward afterwards.Material drops on the vibration drying bed after sending into system, by the vibration of vibrated bed and the upwards effect unrestrained repeatedly fluidized drying of quilt down of mobile thermal current.The particle of upper bed falls into behind lower floor's bed further dry by thermal current again, is discharged by the air-locked type discharger until reaching qualified moisture again.This method has must advantage, but because the difficulty of the control of the goods fluid on the vibration drying plate is very big, and the material bed pressure drop of vibrated bed is big, and the material needed power of kicking up is very big, has brought very big energy consumption.In addition, because design principle, the air-flow that granule is made progress constantly lifts, in system the time of staying long, the problem of super-dry can not be well solved, and controls the improper potential safety hazard of bringing easily.And because this system adopts the mode of material and air-flow adverse current, material outlet place air-flow and material all are in maximum temperature, and as the danger that nature takes place, this has not just limited the temperature of dry gas stream in control, make dry effect be adversely affected.
The utility model content
At the problem that prior art exists, it is little that the purpose of this utility model provides a kind of energy consumption, and the efficient height can be avoided granule super-dry and the too high concurrent flow drying device of material outlet temperature.
The technical solution of the utility model is as follows:
A kind of material concurrent flow drying device, this device comprises housing, be wrapped in the outer sealed insulating layer of housing, be arranged on the deflector in the housing, thermal current air inlet and thermal current gas outlet, be provided with more than one feed hopper in described case top, be provided with dump skip at housing bottom, it is characterized in that: described thermal current air inlet is arranged in the upper lateral part of housing, the thermal current gas outlet is arranged in the side lower part of housing, arranges distributing baffle or flow guide bar at the internal upper part fork of described housing, and staggered downward-sloping multilayer deflector is installed in the middle and lower part of housing, three limits and the housing of every layer of deflector are fixed, and integral body is " Z " shape.
Above-mentioned material concurrent flow drying device, described deflector downward-sloping with angle horizontal plane be 25 °～70 °.Described dump skip is material envelope formula dump skip.
The utility model compared with prior art has the following advantages and outstanding effect:
1. the baffle of housing internal upper part or flow guide bar have prolonged the time of staying of material at the housing internal upper part, and violent in this regional heat exchange, hot stream temperature significantly descends, and moisture evaporates in a large number in the material.
2. deflector is fixed, and need not consumed energy, has significantly reduced the energy consumption of device.
3. adopt concurrent, the hot stream temperature highest point is the temperature of charge lowest part just, though and dump skip place temperature of charge is the highest, the temperature of air-flow is minimum herein, housing inner bottom part material and thermal current all can maintain 78 ℃～100 ℃, have therefore solved the too high problem of drop temperature.
4. following current also makes granule reduce in the intrasystem time of staying, has solved short grained super-dry problem, has prevented the tendency of intrasystem spontaneous combustion and blast effectively.
5. because native system adopts the structure of closed negative pressure, the gas in the device can't leak, and has reduced the pollution to environment effectively.
In sum, the utility model is a kind of material drying device preferably, uses native system that water content is reduced more than 15%, has good drying effect, the drying and dehydrating of especially suitable coal industry.
