Abstract
The invention relates to a dedusting grain drying machine, which belongs to the technical field of grain processing machinery and equipment. The dedusting grain drying machine comprises a drying cabin, a hot air blower, a hot air pipeline, a coil pipe and a boiler, wherein the hot air blower is communicated with the drying cabin through the hot air pipeline, the coil pipe is arranged in the drying cabin, and the boiler and the coil pipe are communicated through a hot water pipeline. Since the dedusting grain drying machine uses both the hot air blower and the coil pipe to dry the grains in the drying cabin, the advantages of the hot air blower and the coil pipe are combined together; and thus, drying effect is better and drying efficiency is higher. As an activated carbon purification section is arranged at the air outlet of the hot air blower and a plurality of layers of activated carbon particles are arranged in the activated carbon section at intervals, secondary pollution resulting from blowing of indrawn dust into the drying cabin by the hot air blower can be prevented. Moreover, a corona discharger is arranged after the activated carbon purification section; and the corona discharger ionizes air to form plasma which is carried by air to the drying cabin, thereby achieving the purposes of neutralizing static charges and collecting dust.
Description
Technical field
The present invention relates to a kind of dedusting foodstuff drying device, belong to Cereals Processing Machines equipment technical field.
Background technology
Grain is human lives's necessity, and various countries all pay much attention to grain-production deposit.But before receipts grain puts in storage, because weather or other reason large portion grain do not dry and moldy metamorphism immediately, not only affect grain quality and also potential harm is present in other health.The grain moisture content of new harvesting is generally at about 17%-32%, and the safe moisture of grain storage, about 14%, can store if therefore need safety stock grain must reach safe moisture to grain precipitation.At present, carry out drying mainly adopt following several method to grain, one is the method adopting the sun to be exposed to the sun; Two is the methods adopting fixing warehouse for drying, in use all there is following deficiency in two kinds of methods, first, adopt the method that the sun is exposed to the sun, although cost is lower, but this method is limited to weather and place, so, use inconvenience; And use the method for warehouse for drying, although can not by the restriction of weather, the one-time investment of warehouse for drying be comparatively large, and meanwhile, warehouse for drying is when oven dry amount is less, and its cost run is also higher.
The generic way that current world food is dried adopts vertical grain drying tower.Its thermal source generally comes spontaneous combustion coal, fuel oil, combustion rice husk, stalk, and fuel produces hot blast through Combustion of Hot Air Furnace, hot blast is passed into grain heap, by grain heat-drying.This drying mode shortcoming is more: general about 150 DEG C of the flue gas after fuel combustion, directly enters air, and the flue gas of heat does not utilize, and produces energy waste.It is shorter that hot blast passes the silo time, generally about a second, exchanges thorough, be with the air of temperature of having a surplus directly to enter air and cause energy waste after exchanging.The air simultaneously extracting temperature lower from air again heats.For my north, dry season generally in the winter of cold, outdoor temperature, at about-20 DEG C, extracts-20 DEG C of air and heats, again the gas of about 40 DEG C above freezing is entered in air after heat exchange, and waste is serious.Traditional tower oven dry hot blast needs to penetrate 60-80cm grain heap, and hot blast can produce very large resistance through during grain heap, and energy loss is larger.Traditional tower oven dry operation energy consumption is very large, and drying its general power of 500T drying tower day is 255kw, is all operate power, is mainly used on blower fan, elevator, does not produce oven dry heat.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of good drying effect and with the dedusting foodstuff drying device of dust removing effects.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of dedusting foodstuff drying device, comprise warehouse for drying, air-heater, hot air duct, coil pipe and boiler, described warehouse for drying is provided with grain-entering mouth and grain outlet, described air-heater is communicated with warehouse for drying by hot air duct, the air outlet of described air-heater is provided with active carbon purifying section, also be provided with corona discharger after described active carbon purifying section, described coil pipe is arranged in warehouse for drying, and described boiler is communicated with by hot water pipeline with coil pipe.
The improvement of technique scheme is: be interval with multilayer activated carbon granule in described active carbon purifying section, and described active carbon purifying section two ends are provided with separation net.
The improvement of technique scheme is: described warehouse for drying top is provided with air outlet.
The improvement of technique scheme is: described grain-entering mouth is at least one.
The improvement of technique scheme is: described air-heater is at least one.
The improvement of technique scheme is: described warehouse for drying outer surface is enclosed with heat-insulation layer.
The improvement of technique scheme is: described hot air duct outer surface is enclosed with heat-insulation layer.
The improvement of technique scheme is: described hot water pipeline outer surface is enclosed with heat-insulation layer.
The present invention adopts the beneficial effect of technique scheme to be: 1) owing to being dried the grain in warehouse for drying together with coil pipe by air-heater, combine the advantage of air-heater and coil pipe, and make drying effect better, drying efficiency is higher; 2) because the air outlet of air-heater is provided with active carbon purifying section, in active carbon purifying section, be interval with multilayer activated carbon granule, can prevent air-heater that the dust of suction is blown into the secondary pollution that warehouse for drying causes grain; 3) because warehouse for drying outer surface is enclosed with heat-insulation layer, the heat loss in warehouse for drying can be prevented; 4) because hot air duct outer surface is enclosed with heat-insulation layer, the heat loss in hot air duct can be prevented; 5) because hot water pipeline outer surface is enclosed with heat-insulation layer, the heat loss in hot water pipeline can be prevented; 6) owing to being also provided with corona discharger after active carbon purifying section, this corona discharger ionized air forms gas ions, arrival warehouse for drying is taken out of by air-flow, with electrostatic and dedusting object in reaching, by the common dedusting of active carbon purifying section and corona discharger, active carbon and corona discharger is made to form complementation.
