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,...
