Utility Model Essence

In order to increase the cost-effectiveness and efficiency in the known pyrolysis furnace, crushed tires are worn out, containing the upper and lower parts, interconnected by means of a conical connector Mioro, mounted in the cavity of the upper part of the furnace with the formation of a wall wall and a ceiling with a common gap, the pyrolysis chamber facing down with an open end, nozzles for supplying and removing heating gas and means for removing 1 pyrolysis products, according to a utility model, are fixed on the bottom of the furnace with a concentric pyrolysis chamber a seagull, the cavity of which through its open upper end is connected with a gap between the ceiling of the furnace and the upper end closed by the end of the pyrolysis chamber, there is a grate on the shell for placing tires, made in the form of a removable annular mesh basket having an inner diameter larger than the largest diameter of the shell, and - smaller internal diameter of the pyrolysis chamber, while the contacting surfaces of the conical detachable connection are made with windows for the passage of heating gas.

With this design of the furnace, comprehensive heat treatment of the tires is provided, both in the bunk: the other and the inner diameter.

It is also new that, on the axis of the furnace, a deflector is installed with a clearance on its bottom inside the shell, and a guide flange is fixed on the furnace ceiling for free entry of the upper end of the deflector.

This makes it possible to increase the efficiency of heat transfer due to an increase in the flow rate of heated gas. At the same time, the deflector serves as a centralizer during the lowering and lifting of the upper part of the furnace.

In addition, the shell and deflector contain upper and lower parts, which are interconnected using detachable joints located at the level of the grate, while the upper parts are changed depending on the diameters of the processed tires.

This increases the efficiency of the furnace due to the possibility of transforming it to work with different groups of tire diameters.

To ensure quick and convenient replacement of the upper parts of the shell and deflector, detachable connections are made with bayonets.

Compa ny, verifying the feasibility of implementing a utility model

The furnace for the propholysis of unshredded worn-out tires contains the upper I and lower 2, parts connected to each other by a conical detachable connection, the contact surfaces of which are made with windows 4 for the passage of heating gas. Pyrolysis chamber 5 is installed in the upper part of I netjH, facing open end down. It forms a common gap with the side walls of the furnace and its ceiling.

In the upper part of the furnace there is a tangential pipe b for supplying gas and a means for removing pyrolysis products made in the form of an annular tray 7 with a pipe 8 for outputting pyrolysis products. A shell consisting of upper 9 and lower 10 parts is coaxially mounted on the lower part 2 of the furnace. The cavity of the shell through its open end is connected to the gap by the ceiling of the furnace and the upper end closed by the end of the pyrolysis chamber about. iia of the upper part 9 of the shell, a grate in the form of a removable mesh basket II is installed, the internal dividing of which is larger than the outside diameter of the shell, and the outer one is smaller than the internal diameter of the pyrolysis chamber 5. On the lower part of the 10 shell there is a pipe 12 for removing heating gas. the axis of the furnace on its bottom inside the shell has a deflector consisting of the upper -13 and lower 14 parts. The upper end of the deflector freely enters the guide flange 15, mounted on the ceiling of the furnace. f g The upper and lower parts of the shell and deflector are interconnected using detachable bayonet connections. (Fig.3,4,5), containing a groove 16 and a latch 17. The detachable connections are located at the level of the grate-bottom of the removable ring basket II. The furnace operates as follows; Before starting the furnace, it is assembled; first, the upper removable shell part 9, the upper removable part of the deflector, the upper removable part I of the furnace, depending on the busbars / Metres of the processed tires, and the corresponding ring basket II are selected (see figure). I and 2). The assembly is carried out in the following sequence: On the lower part 14 of the deflector, by rotation, fix its upper part 13 using a bayonet connection (Figs. 3,4,5). In the same way, the upper part of the shell is fixed on its lower part 10. The annular basket II loaded with tires is mounted on the shell. The upper part I of the furnace is installed on the lower part: 2 and a conical detachable joint is fixed 3. After that, the furnace is started by feeding the heating vase to the tangential pipe 6. The heating gas, twisting, enters through the window 4 into the gap between the side walls of the furnace and pyrolysis 5 , rises to the ceiling of the furnace, flows around the upper closed end of the pyrolysis chamber, changing the direction of movement in the opposite direction, enters the gap between the shell and the deflector down to the outlet pipe 12. A comprehensive heating of automobile of the tires in Kaiviepe pyrolysis 5, and their thermal decomposition with the formation of gas, 2 a small phase solid oil and a solid hydrocarbon residue with a metal cord. the schrolysis liquid flows through the openings of the annular basket II into the annular tray 7 and, together with the generator gas, is discharged through the nozzle 12. Further, the generator gas and liquid enter a condenser (not shown), where gas radium is separated from the liquid, the liquid fraction enters the collecting tank, and az-in gas recovery (not shown).

After processing the tire package, the heating gas supply is stopped, the lyrolysis chamber 5 is blown with inert gas or steam, the upper part of the furnace I is lifted, the ring basket And is removed from the furnace, and then another basket 1u is loaded into the furnace and the upper part I is returned on foot the tire pyrolysis process is carried out again and again. At this time, the wire cord and carbon residue are unloaded from the removed basket.

The economic effect is achieved due to the comprehensive heating of the processed tires and increase the efficiency of heat transfer, reduce energy consumption, labor costs of maintenance; ; yvaniya, as well as reducing the height and weight of the furnace.

The profitability of the proposed utility model is also achieved by maintaining the invariability of the lower part of the furnace, which contains the basic problems necessary for the normal functioning of the furnace, when transforming the upper part of the furnace depending on the diameters of the tires being processed.
