Abstract

The utility model relates to a large-scale straw carbonization kiln, which is provided with an enclosed kiln body with a kiln door for loading and unloading materials, a temperature increasing hole which can be opened and closed and is communicated with the inner cavity of the kiln body is arranged on the peripheral wall of the kiln body, and a plurality of oxygen increasing holes which can be opened and closed and are communicated with the inner cavity of the kiln body are distributed on the peripheral wall of the kiln body, a plurality of air flues at the bottom in the kiln body are led out from the lower portion to be communicated to a main air flue, and the main air flue is communicated with a chimney. A helical disk pipe cooling device whose one end is a water inlet and the other end is a water outlet is mounted in the chimney, and a temperature sensor is mounted in the kiln body. The large-scale straw carbonization kiln can carbonize straws in large scale, the bigger the capacity of a carbonizing kiln, the more the raw materials which are held, and the bigger the quantity of carbonizing straws in each time, and the carbonizing period is short. The large-scale straw carbonization kiln is suitable for industrialized production, and is easy for forming industrialized standard, and the operation is easy for standardization. Raw materials which need to be carbonized are charged in a flat-plate raw material car, raw materials are convenient and fast to get into the large-scale straw carbonization kiln, and end products are convenient and fast to get out of the large-scale straw carbonization kiln, and radiating speed is fast. Straws can be carbonized into high grade anthracite coal through utilizing the large-scale straw carbonization kiln.

Description

Large-scale straw charring kiln

Technical field:

The utility model relates to a kind of large-scale straw charring kiln, is used for industrialization charing stalk and produces high-quality anthracite.

Background technology:

Stalk is a kind of wide renewable energy resources of originating, and the stalk land occupation resource of throwing aside in a large number causes topsoil again if burn.A kind of equipment with straw charring is arranged at present, need give birth to hot charing by fashion of extrusion with after the crushed stalk, the degree of charing is low, and unstable product quality has black smoke during burning.

Summary of the invention:

The purpose of this utility model provides a kind of large-scale straw charring kiln, and the charing stalk is realized suitability for industrialized production on a large scale.

The purpose of this utility model realizes as follows: this large-scale straw charring kiln relates to the sealing kiln body that has wicket, after opening, wicket can load and unload material, on kiln body perisporium, be provided with communicate with the kiln intracoelomic cavity can open, close heat mouth, also be furnished with the some oxygenation mouths that can open, close that communicate with the kiln intracoelomic cavity on the kiln body perisporium, kiln body inner bottom part has some flues to draw from the bottom to be communicated to flue collector, and flue collector connects chimney.The various stalks of not pulverizing are put into carbonizing kiln, heating a mouthful given supplying heat source, the general use lighted the stalk heat supply that heats mouth, open all oxygenation mouths, after heating the stalk absorption heat at mouthful place, pyrolytic reaction takes place, stalk is through drying stage, pre-charing stage, charing stage, the rapid heat release of oxygen reaction that the carbon monoxide that above-mentioned three phases produces, methane, ethene, methyl alcohol etc. and oxygenation mouth suck, and carbonic acid gas, water, tar will be gone out by smoke stack emission.Adjustment heats the open and-shut mode of mouth and the unlatching size of oxygenation mouth according to kiln temperature, along with the temperature in the kiln rises, constantly suitably reduce the oxygenation amount of oxygenation mouth, make temperature-stable in the kiln between 400-500 ℃, after 8-10 hour, moisture discharge amount in the chimney is attenuated to almost nil, and closeall oxygenation mouth also seals chimney, and the interior straw charring of kiln this moment is promptly accused and finished.

The kiln body is equipped with temperature sensor, detects the temperature in the kiln in good time.

Refrigerating unit is housed in the chimney, condenses into water and liquid tar when water vapour in the flue and tar process condensing works, remaining gas enters atmosphere.

Refrigerating unit is that an end is that water-in, the other end are the spiral pipe of water outlet, can be used as thermal source output after recirculated water is heated.

The utility model is the charing stalk on a large scale, and the carbonizing kiln volume is big more, and the raw material that is held is just many more, and the amount of each charing stalk is just big more; The charing cycle is short, is fit to suitability for industrialized production, and operation is easy to standardization, is easy to form industrialized standard; Need the raw material of charing to be contained on the flat former truck, raw material advances kiln, the finished product kiln discharge is convenient and swift, and radiating rate is fast.Utilize it straw charring can be become a kind of high-quality anthracite, and then can the deep processing shaped coal, the activation profit rises and becomes gac, mosquito-repellent incense etc.

Description of drawings:

Accompanying drawing is the structural representation of the large-scale straw charring kiln of the utility model.

Embodiment:

With reference to accompanying drawing, a sealing kiln body 1 that has the wicket 2 that is used to load and unload material is arranged, kiln body 1 outer wall is covered with lagging material, the front and back of kiln body 1 can all be provided with wicket 2, on kiln body 1 perisporium, be provided with and can opening that kiln body 1 inner chamber communicates, that closes heats mouthfuls 3, heat mouthfuls 3 modes that are designed on opening, install additional vertical hinged door, also be furnished with some and can opening that kiln body 1 inner chamber communicates on kiln body 1 perisporium, the oxygenation mouth 5 of closing, oxygenation mouth 5 is designed to be equipped with the mode of gate on opening, kiln body 1 inner bottom part has some flues 4 to draw from the bottom to be communicated to flue collector 6, and flue collector 6 connects chimneys 10.It is that water-in 7, the other end are the helical disk tubular type refrigerating unit 8 of water outlet 9 that one end is housed in the chimney 10, and kiln body 1 is equipped with temperature sensor 11, and the probe apparatus of temperature sensor 11 is in kiln body 1, and probe quantity is decided according to kiln body 1 capacity.
