Description

The device relates to the wood processing industry and is intended for the production of charcoal and a mixture intended for the production of charcoal briquettes from waste wood and can be used for independent or additional production at wood processing enterprises.

A device for producing charcoal (DU) is known, which includes a furnace communicating with a pyrolysis chamber containing removable retorts. The device is additionally equipped with a drying chamber with gas flow guiding elements representing vertical columns, while the drying chamber is placed behind the pyrolysis chamber and connected in series with it via air ducts through the walls (RF patent for utility model No. 66334, published on 09/10/2007) .

The closest technical solution chosen by the applicant as a prototype is a device for producing charcoal, including a firebox communicating with a pyrolysis-drying chamber containing removable retorts and gas collectors located under the retorts, [RF patent for utility model No. 74914 publ. July 20, 2008].

The disadvantage of this design is the impossibility of producing a mixture intended for the production of charcoal briquettes, without the use of third-party binder material.

The technical task of the model is to expand the technological capabilities of the device for the production of a mixture intended for briquetting and reduce the cost of its production.

The technical problem is achieved by the fact that the known device contains a furnace communicating with a pyrolysis-drying chamber containing removable retorts equipped with gas collectors located under the retorts with gas ducts for diverting steam and gas into the furnace and for condensation, while the device is additionally equipped with reactors with gas ducts for supplying a gas-vapor mixture from the lower part of the retort to the upper part of the reactors, as well as the gas ducts for supplying the vapor-gas mixture from the lower part of the reactor to the furnace.

Comparison of the proposed solutions with the prototype shows that it differs in the following features:

- the device is equipped with reactors with gas ducts for supplying a gas-vapor mixture from the lower part of the retort to the upper part of the reactors;

- the device is equipped with gas ducts for exhausting ASG from the bottom of the reactor to the furnace.

Therefore, we can assume that the utility model meets the criterion of "novelty."

The utility model can be manufactured on standard equipment using well-known technological processes, using standard units and components. Therefore, it meets the criterion of "industrial applicability".

The proposed technical solution is illustrated by drawings. Figure 1 shows the device in plan, figure 2 is a view along aa.

The device is composed of a furnace 1 and a pyrolysis-drying chamber 2 and consists of a metal casing 11, a hearth 12, a side wall 13. Between the side wall 13 and the metal casing 11 a heater 14 is placed.

In the vault 7 of the pyrolysis-drying chamber 2 and reactors 10 there are openings 15 for installation of removable retorts 5 in the device.

From above, the pyrolysis-drying chamber 2 and reactors 10 are closed by a vault 7 with roof covers 8 installed in a sand gate 9.

Inside the pyrolysis-drying chamber 2 and the reactors 10 are equipped with gas collectors 6 with supporting sheets 16.

The gas collectors 6 at the front of the pyrolysis-drying chamber 2 are equipped with gas flues 3 of the exhaust gas condensate drainage to the upper part of the reactor 10 and the gas flues 4 of the exhaust gas-condensing mixers from the lower part of the reactor to the furnace 1. Gas collectors 6 at the rear of the pyrolysis-drying chamber 2 are equipped with a pipe 17 for venting firebox 1.

The device operates as follows. Initially, wood is loaded into the furnace 1 through the opening of the furnace 18 with the equipped door of the furnace 19 and burned. The resulting coolant is flue gases, through the smoke hole 20 for the exit of flue gases from the furnace 1 is fed into the pyrolysis-drying chamber 2.

Vegetable carbon-containing waste is loaded into a vertical retort 5, with a grill 21 installed in the lower part. The grill 21 prevents the loss of raw materials from the retort 5.

In the pyrolysis-drying chamber 2 through holes 15 in the vault 7, removable retorts 5 with raw materials are installed in the device. The holes 15 in the vault 7 are closed by the covers of the vault 8 installed in the sand gate 9.

When water vapor is released at the rear of the pyrolysis-drying chamber 2, they exit the retort 5, which is installed in the sand gate 9 on the support sheet 16, and enter the gas collector 6. From the gas collector 6, water vapor is sent through the pipe to the vapor 17 to the furnace 1 afterburning.

Removable retorts 5, with finished charcoal, cools naturally. Then, if necessary, the coal is supplied for grinding to a known grinding device suitable for grinding obtained coal, for example, a DIM-B-800 roll crusher. In the reactor 10 install a removable retort 5 with finished charcoal. The reactor is closed with a lid 22.

When steam gases are separated in the front part of the pyrolysis-drying chamber 2, they exit the retort 5 installed in the sand gate 9 on the support sheet 16 and enter the gas collector 6. From the gas collector 6, the vapor gases are directed through the gas ducts 3 to exhaust the ASG to the upper part of the reactor , with a pre-extracted retort 5 with pre-installed charcoal installed there. Passing charcoal in the reactor 10, the droplet phase of the ASG condenses on its surface, and then, the tarred ASG is sent through the flues 4 of the outlet of the ASG from the bottom of the reactor 10 to the furnace 1 for combustion.

The presence of flues for the removal of combined cycle gases into the reactor allows to obtain a mixture intended for briquetting in the process of manufacturing charcoal on this device.

Resin acts as a binder for briquetting. The final product of the proposed installation is charcoal and (or) the mixture is sent to briquetting without adding third-party binder material.

Thus, the claimed useful allows you to get a mixture for the production of briquettes and reduces the cost of not producing it.
