Continuous high temperature and atmospheric pressure desulfurizer

Abstract

The invention discloses a continuous high-temperature atmospheric-pressure desulphurization machine which comprises at least three desulphurization cylinder units and one or more cooling cylinder units, wherein each desulphurization cylinder unit as well as each cooling cylinder unit is provided with an independent frequency modulation motor as a power driving device. According to the reaction process of rubber power desulphurization, the reaction time of rubber power in each desulphurization cylinder unit can be controlled in a segmented mode, and the production accidents of blocking and insufficient desulphurization can be prevented. The cooling cylinder unit can rapidly cool the desulphurized recycled rubber powder, and high-temperature steam of the rubber powder, a softener and an activator can be changed into liquid to permeate the recycled rubber powder, so that damage to the environment is avoided, and the prominent technical problem during waste rubber powder desulphurization is solved. According to the invention, the continuous high-temperature atmospheric-pressure desulphurization machine does not need a rack, has a compact structure and occupies a small space; different types of desulphurization devices can be combined at will to provide convenience for processing different rubber powders; during maintenance, a user only needs to replace a faulted unit; the transportation cost, equipment cost and maintenance cost are greatly reduced.

Description

technical field [0001] The invention relates to a desulfurization device for waste rubber. Background technique [0002] In recent years, the annual waste tires produced in my country have been increasing at a rate of 8% to 10%. In 2012, my country's waste tire production amounted to about 300 million pieces, and the recycling rate was only about 50%, which was less than 30% of that in Western developed countries, resulting in a huge waste of resources. [0003] Waste tires have strong heat resistance, mechanical resistance and degradation resistance. How to deal with waste tires has become a huge social problem. There are three main treatment methods for waste tires: the first method is tire retreading. There are few old tires that can meet the requirements of tire retreading. Major safety accidents occur; the second method is oil refining, the disadvantage is that it will release a large amount of toxic and harmful gases such as hydrogen sulfide, sulfur dioxide, benzene,...

Problems solved by technology

In 2012, my country's waste tire production amounted to about 300 million pieces, and the recycling rate was only about 50%, which was less than 30% of that in western developed countries, resulting in a huge waste of resources

There are three main treatment methods for waste tires: the first method is tire retreading. There are few old tires that can meet the requirements of tire retreading. Major safety accidents occur; the second method is oil refining, the disadvantage is that it will release a large amount of toxic and harmful gases such as hydrogen sulfide, sulfur dioxide, benzene, xylene, etc., and the toxic and harmful waste residues also seriously pollute the land and water sources; the third method is after desulfurization Produce recycled rubber, this treatment method can make the utilization rate of waste tires reach more than 99%, and does not cause harm to the environment

[0004] The disadvantages of traditional high-pressure desulfurization tanks are: continuous production is not possible, production efficiency is low, and safety accidents are prone to occur; there are also continuous desulfurization equipment, such as patent 201110130933. The reason is that rubber desulfurization is an extremely complicated chemical reaction. During the flow of waste tire rubber powder, the rubber powder will expand, because the material flow of each desulfurization pipe cannot be controlled separately, which may easily cause blockage of the desulfurization pipe. ;Because the temperature of the reclaimed rubber powder at the outlet of this technical solution is relatively high, the reclaimed rubber powder together with the gasified softener and activator are sent to the discharge conveyor, which easily causes the gaseous softener and activator to be discharged into the air, causing great harm to the environment; and the structure is complex and difficult to adjust the process
