ABSTRACT:
This application claims the benefit of Estonian Patent Application No. 199900336, entitled Cyclic Installation for Utilization of Waste Containing Polymer Compounds, and filed Oct. 27, 1999.
The invention belongs to the field of devices for the utilization of waste products containing polymeric compounds, primarily worn automobile tires.
Worn-out tires of all types and uses present a serious ecological problem for the entire world. With a rather low storage density (approximately 160 kg/m
3
), they require a great deal of storage space and may cause the combustion and instability on the whole of other waste products. The total accumulated mass of old automobile tires in developed countries is, according to different estimates, from 10 to 20 kg for each resident. Synthetic or natural rubber, which according to its chemical composition is a product of the polymerization of unsaturated hydrocarbons, is the primary component of the rubber mass.
The existing patent is EE02943B1 Int. C1.6 CO8J 11/2; C10G 1/10 “Utilization of rubber waste products by a solid shale heat carrier decomposing thermal process.” The holders and authors are: K. Senchugov, V. Chikul, A. Kaidalov, L. Shaparenko, A. Popov, B. Kindorkin, A. Elenurm, M. Marguste, Ju. Lushnyak; the patent application publication date is Dec. 15, 1995.
The existing invention relates to the utilization of polymeric waste products, primarily those of worn automobile tires, by means of thermal processing (semi-coking) with the goal of the manufacture of oil and gas for the chemical and power industries.
The complete utilization of rubber waste products takes place according to the solid heat-carrier method with the destructive thermal processing of a mixture of crushed rubber and shale.
This is a rather complicated technological process, which requires additional handling of the automobile tires—the crushing, which takes place at a low temperature (no more than 800° C.) and involves the necessary addition of shale.
The existing utility model is EE9800195U1, Int. C1.6 CO8J 11/12; C10G 1/10“Line for the complete utilization of waste rubber tires”, authors: A. Reiner, M. Marguste, Ju. Pjarnits, Ju. Kann, Ju. Kriis, publication date of the application Apr. 15, 1999.
The existing line consists of a semi-coking mechanism, a mixing tank, a furnace and a rubber crusher.
The process for the utilization of waste rubber tires proceeds in two stages, includes a preliminary crushing, and is complicated and time-consuming, which significantly increases the cost of its use.
The goal of the present invention is:
to present a cyclical apparatus for the utilization of waste products containing polymeric compounds, primarily those used in automobile tires, with a high degree of utilization (more than 90%) due to the high temperature (up to 1400° C.) of the consuming gases.
Taking into consideration the need to protect the environment and the need to resolve the established goal, the cyclical apparatus for the utilization of waste products containing polymeric compounds, primarily those used in automobile tires, contains two basic assemblies:
a gasification unit, consisting of a gas generator
1
and a primary air blower
2
,
an assembly for the utilization of organic gas consisting of a combustion and utilization injector
24
, a gas line
13
of 130-160 mm diameter, a valve for secondary air
23
of 100-250 mm diameter, a secondary air blower
21
a pipe
20
of 400-600 mm diameter, insulated from within by heat-resistant concrete.
The gas generator
1
is made up of a tank (outer shell)
3
, of 3-4 meters in diameter and 4-5 meters high, containing a chute
17
for loading automobile tires and removing ashes, a reactor
4
with an upper spherical lid
10
upon which a chimney
14
of 150-300 mm diameter and height of 1-2 meters is positioned.
The bottom of the reactor,
4
, contains from 80 to 120 injectors for the introduction of primary air into the reactor
4
.
The present invention permits a significant increase in the process's degree of utilization (up to 90%), due to the increase in the temperature of the consuming gases, and at the same time significantly lowers the cost of the utilization process.
The invention is presented in drawings.
