Description

Heat treatment system with circulative cooling function

Technical Field

The invention relates to the technical field of material heat treatment, in particular to a heat treatment system with a circulating cooling function.

Background

With the expansion of cities in China and the gradual implementation of the policy of turning partial rural areas into towns, pollutants such as household garbage discarded by urban residents, sludge of sewage plants, leachate of garbage incineration plants, kitchen garbage, biological garbage of farms and the like are rapidly increasing, and the pollution of the pollutants to the living environment of people is urgently solved. At present, two kinds of landfill and incineration are adopted in most places for treating urban domestic garbage, and the landfill wastes land and is accompanied with the problem of seepage of dirty water of garbage at the bottom of a pit, so that the land and underground water resources are seriously polluted. If the burning temperature of the waste and the emission treatment of the flue gas are not well controlled, toxic gases such as fly ash, sulfur oxide, hydrogen chloride, dioxin and the like can be discharged to the atmosphere, and serious harm can be caused to any living beings.

If the huge resource can be screened and classified, then the organic garbage is subjected to environment-friendly heat treatment, and the produced fuel gas can be used for extracting chemical products and burning for power generation, so that the waste is recycled.

Furthermore, with the improvement of the living standard of people, automobiles go into thousands of households, the automobiles generate a large amount of waste tires, and the disposal of the tires also becomes a very troublesome problem. The reclaimed rubber becomes the third major rubber source in China, the profitability of the industry is rapidly increased, the development situation is good, and as China is not the main production place of natural rubber and relatively speaking, rubber resources are relatively in short supply, the reutilization of the waste rubber can relieve the condition of resource shortage and alleviate the problem of environmental pollution, and has profound practical significance.

The conventional heat treatment furnace bottom burns biomass and garbage, and has the following defects:

1. the products after heat treatment are not cooled and collected, so that the recovery efficiency is low.

2. Biomass and garbage are accumulated and combusted, the combustion is not thorough, toxic substances are easy to generate, the body health of workers is influenced, or secondary environmental pollution is caused;

3. an exothermic reaction occurs in the combustion process of the garbage, and the existing heat treatment furnace has no mechanism for correspondingly treating the redundant heat, thereby causing waste;

4. substances which need to be isolated from oxygen decomposition, such as heat treatment, cannot be treated, and the applicability is not high;

5. the waste rubber material particles can be retained on the shaft of the shaft screw conveyor, so that residual materials are burnt and even adhered to the shaft screw conveyor, the burnt materials adhered to the shaft screw conveyor are difficult to clean, and burnt materials are doped in new materials entering a machine barrel, so that the quality and the yield of regenerated rubber raw materials are influenced. The existing waste rubber normal-pressure continuous regeneration equipment adopts a steam-free normal-pressure continuous regeneration mode, and has the problems of easy generation of screw and machine barrel sticky materials, easy carbonization of materials, uneven regeneration, large Mooney fluctuation, large peculiar smell of the regenerated materials, unstable quality and the like in the production process;

6. when the waste tires are treated, an intermittent feeding mode is usually adopted, the whole process is not continuous, and the efficiency is low; and the tire fragments are piled up together for carbon black after the reaction is gathered into a cluster, is not favorable for follow-up discharging, and is easy to block the reactor after long-time use, and needs to be cleaned regularly, thus affecting the working efficiency. Meanwhile, a common hopper is additionally provided with a screw rod for feeding, and because the tire fragments have elasticity, the discharge hole is blocked during discharging, so that the discharging is influenced.

In summary, in the social and economic activities, the application of heat treatment (thermal decomposition, thermal reduction) is that no matter in the environmental protection field, the material regeneration field, or the coal chemical industry field, a more intensive, more energy-saving, more environment-friendly, efficient and more convenient equipment technology is needed, and the technology can exert its characteristics in the above fields.
