Abstract

The invention discloses a technique for recovering smoke dust recovering and extracting pyroligneous liquor and wood tar in the process of making charcoal by using straws. The technique comprises the recovery of the smoke dust and the extraction of pyroligneous liquor and wood tar, and is characterized in that a smoke tube is arranged at the outlet of a charring kiln; the smoke tube is in an interlayer type; cooled water is filled in the interlayer; and an atomized water spray thrower is arranged at the highest position of the smoke tube to wet the smoke dust in the charring process which is recovered by a hopper, i.e. the pyroligneous liquor and the wood tar primary solution. The fertilizers of the straws per ton can be used for 2 mu of lands, and can prevent insects and sterilize due to the tar contained therein, the grains produced by farming is free of chemical fertilizers and pesticides; the processes of making charcoal by using the straws, cooking, getting warm to farming do not have any pollution, thus the technique is a true project of saving energy and protecting the environment.

Description

Flue dust in a kind of process of making charcoal by using straws reclaims and " pyrolkigneous liquid ", " wood tar " extractive technique

Affiliated field: the present invention relates to a kind of the recovery and reach " pyrolkigneous liquid ", " wood tar " extractive technique with the flue dust in the agricultural crop straw charcoal processing carbonization process.

Background technology: China is large agricultural country, and every product 1kg grain just has the 2kg stalk.

Calculate every mu by land area and can produce 1 ton of stalk, but 1 ton of per 4 tons of stalk charcoal processing, and the flue dust in the charcoal processing carbonization process contains multiple organic substance and " pyrolkigneous liquid ", " wood tar ", can prepare agricultural fertilizer 5m ³For using in 2 mu of farmlands." pyrolkigneous liquid ", " wood tar " have improve the soil, the insect protected sterilization promotes the plant growth, many effects such as degrading pesticide residues, especially " pyrolkigneous liquid " abroad (beautiful, Japan and Korea S.) be applied to aspects such as agricultural production, food processing, medicines and health protection, gardening, Lin Guo already, with straw charcoal processing carbonization process extract " pyrolkigneous liquid ", " wood tar " has research, explores value.

Summary of the invention: the flue dust that the purpose of this invention is to provide in a kind of process of making charcoal by using straws reclaims and extracts " pyrolkigneous liquid ", " wood tar " technology.

Technical measures of the present invention are in order to achieve the above object: the charcoal base of straw press forming is gone into the flue dust that kiln igniting produced and is entered interlayer chimney and upright chimney, through the spray of the cooling of cooling water and atomized water spray thrower with the flue dust condensation, reclaim through funnel, be " pyrolkigneous liquid ", " wood tar " stoste.

Advantage of the present invention:

1, but 3-4 mu of ground stalk charcoal processing is 1 ton, and enough average family heatings were cooked with 1 year.

2, the stalk on 1 mu of ground regenerant in carbonization process can supply 2 mu of fertilizer that use in the farmland, can insect protected, sterilization, kind ground be without fertilizer and pesticide.

3, cook from the making charcoal by using straws to the heating, farming does not all have any pollutant emission and really accomplishes energy-conserving and environment-protective.

4, the present technique difficulty is low, and is understandable, be easy to do, easily popularize.

5, from process of making charcoal by using straws, reclaim flue dust, extraction " pyrolkigneous liquid ", " wood tar " they are that initiative has originality both at home and abroad.

Description of drawings: the present invention is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the cutaway view of interlayer chimney of the present invention.

Fig. 2 is the stereogram of atomized water spray thrower of the present invention.

Embodiment: the present invention is this realization: crushed stalk, press forming is gone into the kiln igniting and is begun to heat up, moisture content in the stalk, oil content, various volatile materials enter in the interlayer chimney 1 shown in Figure 1 with flue gas, owing in the interlayer cooling water 2 is arranged, chimney inwall 3, relative temperature is lower, flue-gas temperature is up to more than 300 ℃, meet cold condensed water and the wood tar of just condensing into, flow into funnel 4 along chimney inwall 3, another part particulate charcoal, flue dust and nitrogen oxide, meet the water that atomized water spray thrower 6 shown in Figure 2 is sprayed through upright chimney 5 risings, flue gas drenched reduce to funnel 4 together, be " pyrolkigneous liquid " through exporting 9 outflow recovery, " wood tar " stoste, verify through farming, animal husbandry and fishery Bioexperiment research center, the Inner Mongol, the every 100g of this thing is nitrogenous 0.41%, phosphorus 0.22%, potassium 287.96mg, organic 49.96% (survey report NO.09083100789).Cooling water is inlet 10 inflows by the parallel bottom water of interlayer chimney in the interlayer of interlayer chimney 1, flow out by upright chimney 5 most significant end delivery ports 11 again, atomized water spray thrower 6 has all micropores 7 for the rounded lower portion inboard, and a water valve that communicates with the water source 8 arranged, place the top and the inwall 3 of upright chimney 5 tightly to assemble, prevent the flue gas leakage.

Claims

1. the flue dust in the process of making charcoal by using straws reclaims and " pyrolkigneous liquid ", " wood tar " extractive technique, it is characterized in that: the charcoal base of stalk press forming go into flue dust that kiln igniting produced enter interlayer chimney (1) and upright chimney (5) through the spray of the cooling of cooling water (2) and atomized water spray thrower (6) with the flue dust condensation, reclaim through funnel (4).

2. reclaim and " pyrolkigneous liquid ", " wood tar " extractive technique according to the flue dust in the described a kind of process of making charcoal by using straws of claim 1, it is characterized in that: have cooling water (2) to be entered by parallel bottom inlet (10) in the interlayer of described interlayer chimney (1), the most significant end outlet (11) of upright chimney (5) is flowed out.

3. according to claim, flue dust in described a kind of straw charring process reclaims and extracts the technology of " pyrolkigneous liquid ", " wood tar ", it is characterized in that: described atomized water spray thrower (6) is for circular, and lower inside has all micropores (7) and a water valve that communicates with the water source (8) is arranged.
