The heat stirring kiln comprises a kiln body, wherein the kiln body is a two-layer side wall structure and divided into an inner side wall and an outer side wall, a heat cavity is formed between the inner side wall and the outer side wall, the inner edge of the heat cavity is circumferentially provided with a spiral separation plate from top to bottom, the heat cavity forms a spiral heat passage through the spiral separation plate, one end of the spiral heat passage is provided with a heat opening, the other end is provided with a heat outlet, the axis of the kiln body is provided with a stirring shaft, the stirring shaft is provided with a plurality of stirring blades, the tail end of the stirring shaft is provided with a driving mechanism, the upper end surface of the kiln body is provided with an upper end cover, the upper end cover is provided with a feeding opening, the lower end surface of the kiln body is provided with a lower end cover, and the lower end cover is provided with a discharging opening. By adopting the technical scheme, the effect for pyrolyzing the polluted soil is good, and the speed is high; moreover, the equipment integration property is high, the size is small, the energy consumption is low, and the cost is greatly reduced.
Description
Technical field
The present invention relates to field of Environment Protection, be specifically related to a kind of thermal agitation kiln for Pyrolysis Contamination soil.
Background technology
China mostly adopts incineration technology in the time processing hazardous waste and contaminated soil, and its technique is simple, and it is convenient to implement, but burn the character of directly having destroyed soil itself, make soil lose original function, and energy consumption is higher, a part of combustion product easily produces atmosphere pollution.Compare incineration technology, the pollutant that hot analytic technique separates in soil by mode of heating has been subject to increasing attention.While using hot analysis mode, because temperature used is not too high, if contaminated soil or static, heat is difficult to evenly thoroughly reach each several part contaminated soil, its treatment effeciency is also lower, and heating equipment is to be generally wound around reaction kiln with hot channel, and overall structure is disperseed too fat to move huge, heating equipment can be gathered together with reacting kiln so be badly in need of at present one, and with the reaction kiln of agitating device.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of thermal agitation kiln for Pyrolysis Contamination soil is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of thermal agitation kiln for Pyrolysis Contamination soil, comprise kiln body, described kiln body is double side walls structure, be divided into madial wall and lateral wall, between described madial wall and lateral wall, form heating chamber, in described heating chamber, edge is circumferentially provided with helical baffle from top to bottom, described heating chamber forms a spiral Tong Redao by described helical baffle, described spiral Tong Redao one end is provided with Tong Rekou, the other end is provided with heating outlet, be provided with in the heart shaft in described kiln axon, on described shaft, be provided with multiple paddles, be provided with driving mechanism at described shaft end, on the upper surface of described kiln body, be provided with upper end cover, on described upper end cover, be provided with charging aperture, on the lower surface of described kiln body, be provided with bottom end cover, on described bottom end cover, be provided with discharging opening.
Preferably, the direction of heat flow of described spiral Tong Redaonei is contrary with the contaminated soil feedstock direction in described kiln body.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, the effective speed of pyrolysis purifying contaminated soil is fast, and integration of equipments is high, and volume is little, and energy consumption is low, and cost reduces greatly.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of thermal agitation kiln for Pyrolysis Contamination soil, comprise kiln body 1, described kiln body 1 is double side walls structure, be divided into madial wall 11 and lateral wall 12, between described madial wall 11 and lateral wall 12, form heating chamber 13, circumferentially be provided with from top to bottom helical baffle 2 on the interior edge of described heating chamber 13, described heating chamber 13 forms a spiral Tong Re road 21 by described helical baffle 2, 21 one end, described spiral Tong Re road are provided with logical heat mouth 22, the other end is provided with heating outlet 23, on described kiln body 1 axle center, be provided with shaft 3, on described shaft 3, be provided with four paddles 4, be provided with driving mechanism 5 at described shaft 3 ends, on the upper surface of described kiln body 1, be provided with upper end cover 14, on described upper end cover 14, be provided with charging aperture 15, on the lower surface of described kiln body 1, be provided with bottom end cover 16, on described bottom end cover 16, be provided with discharging opening 17.
Preferably, the direction of heat flow in described spiral Tong Re road 21 is contrary with the contaminated soil feedstock direction in described kiln body 1.
Principle of the present invention:
The hot-fluid of heat supply is along flowing on spiral Tong Re road 21 screws, for providing pyrolysis, the soil in kiln body 1 analyses needed heat, paddle 4 in kiln body 1 Stirring soil in the time that contaminated soil is analysed in pyrolysis, resolves its thermally equivalent, after having purified, by discharging opening 17, soil is discharged.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
