Description

PLANT FOR PYROLYSIS OF RUBBER PRODUCTS

The utility model relates to the field of solid waste processing, and can be used in particular for the disposal of automobile tires.

Known Installation for the burning of worn-out tires (p. USA 5313894, MKI V09B 3/00, publ. 24.05.94). It has two chambers in the form of two vertical cylinders with water cooling and a perforated bottom. Under the bottom of each cylinder there are ventilation chambers through which air enters the cylinders. Between the cylinders there is a third afterburner, connected to the first two at different levels for better circulation of the flow in it.

In the upper part of the afterburner there is a flue gas outlet. Thus, air and flue gases move in countercurrent.

Also known is a Installation for burning tire covers (Sec. USA No. 5335. MKI F23B, publ. 09.08.94). It has a main chamber with air supply from the environment and a afterburner with a device for burning combustion products obtained in the first stage, for their most complete disposal.

The presence in the known installations of an additional afterburner increases their durability and dimensions.

Closest to the claimed device is a waste pyrolysis unit according to UK patent No. 2256435 (MKI F23G 5/00,

publ. 12/9/92). The installation comprises a chamber with a container placed inside it with a gap on all sides in the form of an open top box for waste dusty material that accumulates heat for heating the waste from a source made in the form of a microwave generator located in the upper part of the chamber. There is also a loading device for feeding pulverized material and shredded waste directly into the container. In addition, the installation is equipped with pipelines with cooling devices for removing material residues and pyrolysis products from the chamber.

This installation requires a specialized heating source and the use of auxiliary materials, which makes the disposal process more expensive.

The objective of the proposed facility is to reduce the cost of disposal of rubber waste.

To solve this problem, in the installation for the pyrolysis of rubber products, containing a chamber with a heating source, a waste container installed in it with a gap on all sides and a pipe with a cooling device for outputting pyrolysis products, according to a utility model, the container is equipped with a removable sealed lid, and the pipeline mounted with the possibility of tight connection with the container.

Making the waste container airtight improves the efficiency of heating the waste to the desired temperature, because all the heat is practically expended on heating the container (chamber walls

thermally insulated as in all furnaces) with the waste contained in it, and this reduces the cost of disposal.

As a result of patent research, the applicant was not able to identify similar design solutions to the problem of waste disposal. This suggests that the inventive device has a novelty.

The inventive installation can be widely used for the disposal of rubber products, both in stationary and field conditions, that is, can be performed mobile, because easy to maintain, therefore, is industrially applicable.

The essence of the proposed technical solution is illustrated by the drawing.

The proposed installation for the disposal of rubber waste contains a chamber 1, which is a furnace with a furnace 2 as a heating source and a cover 3. The furnace 2 is equipped with a device 4 for supplying fuel and air. Inside the chamber 1, a waste container 5 is placed, mounted on four supports 6 with the formation on all sides of the gap between the container and the walls, the bottom and the lid of the chamber 1. The container 5 is equipped with a removable lid 7 with the possibility of hermetic fastening. On the lid 7 there is a pipe 8 for withdrawing pyrolysis products from the container 5. At the same time, a hole 9 is made in the cover 3 of the chamber 1 for the outlet of the nozzle 8 outside the chamber 1. The container 5 by means of the nozzle 8, a tight sealed detachable connection 10 and a pipe 11

connected to a cooling device - a condenser-refrigerator 12. The pipe 11 is installed on the condenser-refrigerator 12 with the possibility of rotation. In the chamber 1 is mounted a chimney 13. The installation is equipped with a container 14 and a trolley 15.

Installation works as follows. The container 5 is loaded with waste products (rubber products, in particular, automobile tires) weighing about 500 kg and hermetically closed with a cover 7 with a discharge pipe 8. Then it is installed on the supports 6 in the chamber 1. The camera 1 is closed with a cover 3, while the pipe 8 is passed into hole 9 of the cover 3. The pipe 11, laid to the side when loading the container 5 into the chamber, is hermetically connected to the pipe 8 by means of a detachable connection 10 made in the form of a hose ..

In the furnace 2 through the device 4 serves liquid fuel and air in a certain ratio to obtain an operating temperature of 350 ± 20 ° C.

The heating of the container 5 with waste flue gases when loading about 500 kg is continued for 3 hours. Free circulation of flue gases in the chamber 1 allows you to effectively and evenly heat the container 5 with the waste. In this case, the latter decomposes with the release of a large amount of gas, which enters the condenser-refrigerator 12, where it turns into an oily liquid - boiler fuel. It is collected in a container 14, supplied under the condenser-refrigerator 12 with the help of the cart 15.

In the winter season, air is used as a cooler, and water at a positive ambient temperature.

Exhaust flue gases from the chamber 1 exit through the chimney 13 and filters (not shown) into the atmosphere.

At the end of the decomposition process, the pipeline 11 is disconnected from the pipe 8 and taken to the side. Remove the lid 3, take out the container 5. Remove the lid 7 and unload the solid residue, which by weight is about 10 percent of the weight of the waste. It is a valuable raw material for asphalt plants.

The installation is easy to maintain and requires minimal waste unification costs. It can operate all year round in the open air, and can use part of the boiler fuel received in it as fuel, which further increases the efficiency of the installation, i.e. reduces disposal costs.

The fuel fluid obtained at the pilot plant was tested at the boiler unit of the Experimental Base of JSC Chelyabinsk Road Machine Plant named after Kolyuschenko. Currently, a pilot plant is being installed there.
