Description

Energy-conservation rapid drying device
Technical field
The utility model belongs to the field that the drying of wood is handled, and specifically, it relates to a kind of is the energy-conservation rapid drying device of medium with the hot blast.
Background technology
Chang Yong method for drying wood comprises conventional drying, high temperature drying, removal moisture drying, solar energy drying, vacuum drying, dielectric drying, microwave drying and flue gas drying etc. so far, wherein conventional drying refers to make drying medium with the normal pressure humid air, make thermal source with steam, hot water, furnace gas or deep fat, the indirect air, the drying medium temperature is below 100 ℃; Can be divided into Natural Circulation hothouse and forced circulation compartment kiln according to the medium circulation characteristic, wherein forced circulation compartment kiln is divided into indoor type against the wind, indoor fan type, chamber terminal fan type and Puffer type again.Existing dry kiln has tangible shortcoming at aspects such as energy-conservation, reduction of discharging, environmental protection, quality on the market, and the device structure complexity, and investment is big, and therefore very difficult adaptation, is necessary to improve instantly to environmental protection and energy-conservation new demand.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation rapid drying device, it has overcome in the dry run that timber is easy to crack, distortion, look become, drying time, length waited bottleneck, problems such as Combustion of Hot Air Furnace chamber non-complete combustion of fuel have also been overcome, realize high-effect, high-quality, low emission, effect cheaply.
The purpose of this utility model is achieved in that energy-conservation rapid drying device comprises deduster, hot-blast stove and dry kiln, is connected with smoke pipe between deduster and the dry kiln, is connected with warm-air pipe, cool air hose between hot-blast stove and the dry kiln; Be provided with heat exchanger tube in the described hot-blast stove, heat exchanger tube is staggered with positive triangle, and the sidewall of hot-blast stove is provided with the secondary air mouth; Also be connected with smoke pipe between described dry kiln and the hot-blast stove, the upper end in the dry kiln is provided with air channel dividing plate, circular arc deflector, deep bead, and the side in the dry kiln is provided with the water conservancy diversion deep bead, and the hot blast axial flow blower is arranged on the dividing plate of air channel.
The beneficial effects of the utility model are:
One, realized the seamless combination of stove and kiln, overcome other drying equipment structure complexity, investment is big, and dry mass is poor, and arid cycle is long, and toxic emission is big, and the shortcoming that not environmental protection is not energy-conservation really meets the requirement of the energy-conserving and environment-protective drying of wood of new generation.
Two, owing to farthest completing combustion of fuel, flue gas can take full advantage of, and the waste gas of discharge is totally pollution-free, reduces drying cost and environmental protection.
Three, the supervising device that kiln is interior and stove is provided with, the operator can understand the drying regime in the kiln at any time.
Four, flame does not have direct contact heat-exchanging pipe, and stove prolongs service life.
Five, the refluence setting in the kiln body makes indoor air pressure more even, reduces turbulent phenomenon and takes place, and improves rate of drying and dry quality.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the energy-conservation rapid drying device of the utility model.
Fig. 2 is the front view of hot-blast stove.
Among the figure: 1-deduster, 2-warm-air pipe, 3-smoke pipe, 4-smoke pipe, 5-dry kiln, 6-axial flow blower, 7-air channel dividing plate, 8-circular arc deflector, 9-deep bead, 10-water conservancy diversion deep bead, 11-plank, 12-cool air hose, 13-hot-blast stove, 14-secondary air mouth, 15-heat exchanger tube, 16 insulation materials.
The specific embodiment
As shown in Figure 1 and Figure 2, the energy-conservation rapid drying device of the utility model comprises deduster 1, hot-blast stove 13 and dry kiln 5, is connected with smoke pipe 4 between deduster 1 and the dry kiln 5, is connected with warm-air pipe 2, cool air hose 12 between hot-blast stove 13 and the dry kiln 5; Be provided with heat exchanger tube 15 in the described hot-blast stove, heat exchanger tube is staggered with positive triangle, and the sidewall of hot-blast stove is provided with secondary air mouth 14; Also be connected with smoke pipe 3 between described hot-blast stove and the deduster, the upper end in the dry kiln is provided with air channel dividing plate 7, circular arc deflector 8, deep bead 9, and the side in the dry kiln is provided with water conservancy diversion deep bead 10, and hot blast axial flow blower 6 is arranged on the dividing plate of air channel.
Air outlet warm-air pipe 2 and the smoke pipe 3 of hot-blast stove 13 are provided with device for monitoring temperature, and described device for monitoring temperature comprises thermometric instrument, temperature sensor.
Be provided with the checkout gear of wet and dry bulb temperature and humidity in the dry kiln 5, allow the user grasp the interior situation of kiln more intuitively, improve dry mass greatly.
Timber 11 neat stackings on plate layer frame, are sent into precalculated position in the kiln with fork truck, close wicket, finish the loading of kiln action.Culled wood fuel is sent into burner hearth to burn, the unburnt fuel of part is brought secondary combustion chamber into flue gas, realize the real completing combustion of fuel by the size of regulation and control secondary air mouth, also regulated the flue-gas temperature that enters heat exchanger tube simultaneously, improve heat exchange efficiency.Observe stove into and out of the place, air port and into and out of the device for monitoring temperature at flue gas mouth place, guarantee the desirable kiln hot blast temperature that advances.The hot blast of recuperative furnace output is brought in the kiln through connecting pipe and hot blast discharge pipe, constantly be circulated in air channel, circular arc deflector, refluence deep bead and each rick between air channel dividing plate and the kiln top gap in stacking by the hot blast axial flow blower in the kiln with certain speed, thereby to the oven dry of the timber forced convertion in the kiln and evenly heating, oven dry rear section residue is brought into the air of certain heat and is carried out further heat exchange and circulation again in the stove, utilized heat energy greatly, reduced fuel cost, real realization exhaust gas utilization, energy-conserving and environment-protective.The flue gas that recuperative furnace is discharged carries out heat convection through the air in kiln internal flue and the kiln after filtering by deduster again, effectively utilized the heat of useless flue gas, guaranteed the stability of kiln temperature, the overall temperature difference of desiccated wood is little, prevents that timber from the part occurring and tearing the generation of substandard products such as distortion.The fuel cost that while also reduces, energy-conserving and environment-protective.
The kiln body of dry kiln 5 adopts aluminium alloy structure, and its outer wall coats insulation material 16, and described insulation material is any one in phenolic aldehyde heat preserving material, polyurethane heat insulation material, these three kinds of materials of rock wool.
