Abstract

The utility model discloses a drying cylinder of internal-heating continuous biomass charring equipment. The drying cylinder mainly consists of a cylinder body 1, positioning rods 2 and brackets 3, wherein the upper part of the contour of the cylinder body is of a semispherical shape, the lower part is of a cylindrical shape, and the bottom is open; the thickness of the cylinder body is generally 2.5-3mm; four brackets 3 are welded at the lower part of the drying cylinder; the brackets 3 can be directly mounted at a taper opening of the furnace body without fixed connection; four positioning rods 2 are arranged at the upper middle part of the drying cylinder; the positioning rods are used for positioning the drying cylinder; and when the drying cylinder is mounted and dismounted, the operation is convenient by adjusting the length of the positioning rods. The drying cylinder divides a biomass raw material in the furnace body into thin layers; and through the countercurrent hot air drying principle of the thin layers, the material drying can be accelerated, the equipment productivity is improved, and the charcoal quality is improved.

Description

A kind of interior heating continuous biomass carbonization device dram

Technical field

The utility model belongs to field of renewable energy technology, be specifically related to a kind of interior heating continuous biomass carbonization device dram, especially can realize treating the thin layer adverse current warm air drying of the biomass material that charing is processed, be applicable to comprise the dry pre-treatment before the biomass material pyrolysis charring of different kind organism matter granular fuel.

Background technology

Charcoal can be applicable to a plurality of fields, can improve soil in agriculture production, increase soil fertility, improve plant growth environment, charcoal has active effect to environment protection, it has good absorption property and stable chemical property, can anti-strong acid, highly basic, can stand water logging, the High Temperature High Pressure effect is not broken, the objectionable impuritiess such as curable heavy metal and remains of pesticide; At energy field, charcoal is good " carbonized biomass coal ", and calorific value is high, cleanliness without any pollution, and efficiency of combustion is high, the fossil energies such as alternative combustion gas, coal.Biomass charing device mostly is laboratory scale at present, take basic research as main, charcoal output is lower, character is changeable, and the higher biomass granule fuel for water ratio especially, after hot blast takes lower floor's material moisture to the upper strata condensation, easy pigment upper materials, greatly reduce charcoal quality and charcoal yield, therefore, before the biomass granule fuel pyrolysis charring, be necessary to carry out drying treatment.

Summary of the invention

For further improving biomass carbonated equipment charing efficiency and product quality, the utility model discloses a kind of interior heating continuous biomass carbonization device dram, utilize thin layer counter current drying principle, biomass material is carried out before entering the pyrolysis charring district to drying and processing.

The utility model is to reach the technical scheme that this purpose takes to be: a kind of interior heating continuous biomass carbonization device dram comprises cylindrical shell, backstay, support.It is characterized in that cylindrical shell is the core of dram, dram is provided with 4 backstays and 4 supports, and backstay is welded on position on the upper side, cylindrical shell middle part, and support welding is at cylinder body bottom.

Described cylindrical shell adopts the good steel plate of heat transfer property to make, and steel plate thickness is generally at 2.5～3mm, and cylindrical shell appearance profile top is semisphere, and bottom is cylindrical, presses and forms by punching press or volume, the cylindrical shell bottom end opening.

Described backstay is comprised of swivel nut, screw rod and setscrew nut etc., and rotary screw can be regulated the length of backstay, facilitates the dismounting of the installation of dram in body of heater.

Described dram is with body of heater without being fixedly connected with, and support is arranged on the cone ports top of body of heater, and backstay is positioned on the inner cylinder face of body of heater, but dram barrel diameter Seriation Design, according to material characteristic, is selected the dram of different barrel diameters.

A kind of interior heating continuous biomass carbonization device dram of the present utility model, can make the material shape lamellar in burner hearth, and the thin layer material is slowly descending, and the hot blast that the biomass oxidative pyrolysis produces is up, can accelerate the rate of drying of material.Dram is with body of heater without being fixedly connected with, and installation and removal are convenient.

The beneficial effects of the utility model are, utilize thin layer adverse current warm air drying principle, before pyrolysis charring, biomass material are carried out to drying and processing, can improve equipment charing efficiency.Especially to grain forming fuel, can effectively prevent the upper materials pigment that cause because of water vapor condensation, guarantee carbonization quality, improve the charcoal yield.

The accompanying drawing explanation:

Fig. 1 is a kind of interior heating continuous biomass carbonization device dram schematic diagram of the present utility model.

Fig. 2 is the positional lever structure schematic diagram.

Fig. 3 is interior heating continuous biomass carbonization device dram scheme of installation.

In Fig. 1, (1) is cylindrical shell, and (2) are backstay, and (3) are support.

In Fig. 2, (4) are swivel nut, and (5) are setscrew nut, and (6) are screw rod.

In Fig. 3, (7) are dram, and (8) are body of heater.

Embodiment:

As shown in Figure 1, the core of dram is cylindrical shell 1, cylindrical shell 1 appearance profile upper part is semisphere, lower part is cylindrical, its radius is generally at 220～300mm, steel plate punched or volume that available 2.5～3mm is thick are pressed into, the cylindrical shell bottom end opening, and the cylindrical shell that is heated can be contacted thermal conduction formula drying to material.

2 pairs of dram of backstay play the role of positioning, and generally install 4 groups.Backstay 2 mainly is comprised of swivel nut 4, setscrew nut 5 and screw rod 6 three parts, and swivel nut 4 is welded on the position of cylindrical shell upper middle, but when dram is installed, manual regulation screw rod 6 is to suitable position, and the setscrew nut 5 that then screws up with a wrench gets final product.

Support 3 is supports of dram, generally installs 4 groups, because support is at the upside in body of heater oxidative pyrolysis district, temperature higher (500～600 ℃), will guarantee physical strength under its hot conditions while therefore designing.

As shown in Figure 2, during installation, dram 7 is directly inserted in body of heater 8 and is got final product, without being fixedly connected with.After installation, support 3 is stuck in the cone surface tip position of body of heater, and the length of regulating backstay 2 can be by the stable placement of dram.

Finally it should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to better case study on implementation, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
