Abstract

The utility model relates to the technical field of wood drying and in particular relates to a wood drying and carbonizing integrated device. The wood drying and carbonizing integrated device comprises a kiln body and an integrated controller, wherein the kiln body is internally provided with a fan, a heater, a water spraying pipe used for spraying atomized water and a steam water channel used for producing saturated steam, the top of the kiln body is provided with a moisture removal window, a motor of the fan is electrically connected with a frequency converter, and the frequency converter is electrically connected with the integrated controller. According to the wood drying and carbonizing integrated device, drying and carbonizing are combined and carried out in one kiln body, difficulty of a drying and carbonizing integrated technology is overcome, wood is cooled and directly carbonized without being taken out from a kiln after the wood is dried, energy consumption is reduced, and effects of saving energy and reducing emission are achieved.

Description

A kind of drying of wood charing integrated device

Technical field

The utility model relates to a kind of drying of wood charing integrated device.

Background technology

Existing is first that timber is dry in dry kiln to the carbonization of wood, and then cooling entering again carried out charing in carbonizing kiln, and this just makes, and the process-cycle is long, equipment cost is high, energy consumption is high, is unfavorable for energy-saving and emission-reduction.And dry treatment temp with charing is different with the wind speed requirement, overcome technical difficulty as wanting integrated needs.

The utility model content

Be to solve the problem that prior art exists, the utility model provides that a kind of rapid drying and charing, energy consumption are low, the drying of wood charing integrated device of automatic control.

Drying of wood charing integrated device described in the utility model, it comprises kiln body and one control

Instrument processed, blower fan, well heater are set in described kiln body, are used for the water jet standpipe of atomized water spraying and for generation of the steam tank of saturation steam, described kiln body top arranges moistureproof window, and described blower motor is electrically connected to a converter plant, and described converter plant is electrically connected to described integrative control instrument.

Drying of wood charing integrated device described in the utility model, its beneficial effect is:

Drying and charing are concentrated in a kiln body carry out, installed the water pipe of atomized water spraying and the tank that produces saturation steam additional in the kiln body, the timber after charing is lowered the temperature, regulated in the kiln body humidity and protects timber when the charing; Blower fan connects a converter plant, can automatically strengthen or reduce wind speed in different steps under the control of integrative control instrument, overcome the difficulty on dry charing integrated technique, kiln discharge is not cooling after the drying of wood directly carries out charing, reduce energy consumption, reached the effect of energy-saving and emission-reduction.

Description of drawings

The picture that this description of drawings provides is used for assisting the further understanding to utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:

Accompanying drawing 1 is side-looking structural representation Fig. 1 of the utility model free stuff quick drying kiln.

Accompanying drawing 2 is side-looking structural representation Fig. 2 of the utility model free stuff quick drying kiln.

Embodiment

The below will describe the utility model in detail with specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

As shown in accompanying drawing 1 ~ 2, drying of wood charing integrated device described in the utility model, its bag

Draw together kiln body 01 and be arranged on the integrative control instrument that kiln is external, be used for controlling the interior working part closure or openness of kiln body and processing parameter, described kiln body 01 is interior arranges blower fan 05, well heater 02, be used for the water jet standpipe 03 of atomized water spraying and for generation of the steam tank (figure does not mark) of saturation steam, described kiln body top is provided for regulating the moistureproof window 07 of humidity in the kiln body, described blower motor 06 is electrically connected to a converter plant, and described converter plant is electrically connected to described integrative control instrument.Kiln body 01 end face has wicket 08, and described wicket has the door system of opening 09 outward.

With the method for above-mentioned drying of wood charing integrated device drying, charred wood, it comprises the steps:

Primary drying: timber to be dried enters in the kiln body, opens the integrative control instrument, its control

Blower fan processed and well heater are started working, and well heater progressively heats kiln temperature to 50 ~ 75 ℃, and timber is carried out conventional drying until moisture content 10% ~ 12%, and primary drying finishes.

Redrying: by in advance thermograde and time that the integrative control instrument sets, one

Body controller control heater begins that gradient increased temperature is to 120 ~ 130 ℃ of kiln temperatures stage by stage from 65 ~ 75 ℃, and wet-bulb depression progressively expands 25 ℃ to, treats that moisture content is down to 2% ~ 4%, and redrying finishes.

The intensification charing: integrative control instrument control heater is rapidly heated to kiln temperature

180 ~ 220 ℃; then keep temperature-resistant; timber is carried out high temperature carbonization; the integrative control instrument is controlled converter plant and then is controlled blower motor power and strengthen simultaneously; the blower fan wind speed strengthens, the steam tank sprays saturated vapor as shielding gas; and to keep wet-bulb temperature in the kiln body be that 99.5 ~ 100 ℃ or oxygen level are less than 2%; after charing finishes, moisture content is less than 0.5%; at this moment make hemicellulose and the degraded of cellulosic pars amorpha in timber, in timber, hygroscopic hydroxyl quantity greatly reduces.Extract such as resin in while timber, terpenoid, tannin, acids contain a large amount of volatilizations such as thing.Thereby the water absorbability of timber reduces greatly, and dimensional stability and erosion resistance significantly improve.

Cooling damping: after charing finishes, integrative control instrument control heater stopped heating and stop spraying saturated vapor, open simultaneously spraying water pipe the timber atomized water spraying is cooled to temperature to 116 in the kiln body ~ 112 ℃, not only play cooling effect, and can make the suitable humidification of almost absolutely dry timber, at this moment again by steam tank spray saturated vapor, with the relative humidity of medium and the water ratio of timber in the raising kiln, and the elimination unrelieved stress, to moisture content be 4% ~ 5%, damping finishes;

Cooling kiln discharge: at this moment, if direct kiln discharge, hot timber is blown by the outer cold wind one of kiln, immediately

Will ftracture, with blower fan to carrying out cooling in the kiln body until the kiln inside and outside temperature difference is down to 25 ~ 30 ℃, get final product kiln discharge, arrive this, dry charing finishes.

The above technical scheme that the utility model embodiment is provided is described in detail, this paper has used specific case principle and the embodiment of the utility model embodiment has been set forth, and the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
