Abstract

The utility model relates to a directly drying device using the waste heat of flue gas. The upper half part of a furnace cavity has a hole plate; the lower half part has wind distributing net; the hole plate and the wind distributing net divide the furnace cavity into a condensing cavity, an evaporation chamber, and a hot wind mixed distributing chamber; the middle of one end of the hot wind mixed distributing chamber has a wind inlet pipe for the flue gas and a wind distributing pipe for air; a thermocouple is arranged in the hot wind mixed distributing chamber; the evaporation chamber has a front and a back furnace doors; a material vehicle and a track for the material vehicle are arranged in the evaporation chamber. The materials are directly dried and blown by the flue gas with positive pressure. Evaporated moisture enters the condensing cavity following the flue gas. One part is led out by the condensing. The other part is drawn away by a chimney. Thereby, the problem of dew-point change in process of the drying is solved. Thermal efficiency is increased. The utility model is ideal equipment which uses the waste heat of the flue gas to dry the non-edibility materials with the high moisture.

Description

A kind ofly relating to the direct-type drying unit that fume afterheat utilizes, be specially adapted to the oven dry of non-food ore deposit plant material product, is the desirable drying plant of industries such as moulded coal factory, charcoal factory, Bricks and Tiles Plant.

Utilize the drying unit of fume afterheat at present, it all is indirect type, utilize fume afterheat heating quirk or heat exchanger tube, and then add hot-air, utilize the hot air dries material, this drying unit, complex structure, the heat energy utilization rate is low, and drying efficiency is low, be difficult for oven dry to moisture up to the material more than 30%, mostly adopt natural air drying.

The purpose of this utility model provides a kind of directly drying unit of the non-food of oven dry ore deposit plant material product of fume afterheat that utilizes.

The utility model is achieved in that a rectangle arch top body of heater with front and back door, in the middle of body of heater one bottom portion, be provided with flue gas blast pipe and air aid distributing pipe, the furnace chamber first half has an orifice plate, furnace chamber is divided into condensation chamber and drying chamber, Lower Half has wind distributing mesh, drying chamber is divided into vaporization chamber and hot blast compounding chamber again, quilt baking material just is contained in the truck and advances the back door to pull out by the Qianmen, Batch Process, flue gas is drawn from boiler flue by air-introduced machine, blasts hot blast compounding chamber through the flue gas blast pipe, according to the temperature of hot blast compounding chamber, can adjust air air distribution amount; The flue gas of band malleation, through wind distributing mesh, the Mars in the flue gas is by under the wind distributing mesh retaining, and rising uniformly, directly material is blown in baking, and moisture evaporated is taken condensation chamber to by the flue gas of rising, and a part of condensation is drawn, and another part is taken away from chimney with flue gas.

This drying unit is compared with existing baking oven, baking kiln: flue gas directly baking blows material, heat energy utilization rate height; Because of having set up condensation chamber, solved baking oven, the dew point variation issue of baking kiln in drying course, improved drying efficiency; Fire door before and after this device has, material advances the back door to pull out with the truck Qianmen, and Batch Process is easy to use, is the ideal device of non-food ore deposit plant material product oven dry.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is the front view of fume afterheat direct-type drying unit.

Fig. 2 is the side view of fume afterheat direct-type drying unit.

Among Fig. 1-2: 1, housing adopts metal or brick building, around in housing (1) and bottom is filled out and is lined with insulation material (2), 3, inwall adopts refractory brick to build by laying bricks or stones or iron plate is made, Lower Half has wind distributing mesh (5) to adopt the wire netting and the angle bar in φ 1-8mm aperture to make Double-level Reticulated, the two layers of mesh spacing is greater than 10mm, be fixed on housing (1) or the inwall (3), be that thermocouple (4) is arranged in the flue gas compounding chamber (13) below the wind distributing mesh (5), flue gas blast pipe (14) is arranged outward, air aid distributing pipe (15), be vaporization chamber (12) above, respectively there is a fire door (16) front and back, in truck track (6) and truck (7) are arranged, truck (7) adopts flower iron or wire netting framework to make.The armored concrete cast is all adopted on abacus (8), arch top (9) on housing (1), also can adopt iron plate making, there are circular hole or slot uniform on the orifice plate (8), the dash platform is arranged around the upper surface aperture, laterally, the waterway slope is arranged vertically, drain into outside the stove always, go up condensation chamber (11) above the orifice plate (8), communicate with chimney (10).

Claims (4)
