Skid-mounted organic solid waste pyrolysis device

Abstract

A skid-mounted organic solid waste pyrolysis device comprises a double-shell sealed furnace body (11), a material conveying device (21) and a plurality of radiant tubes (4), a feeding port (1), a steam outlet (2) and a pyrolysis oil gas port (3) are sequentially formed in the upper wall of the double-shell sealed furnace body (11), a discharging port (6) is formed in the lower wall of the double-shell sealed furnace body (11), the material conveying device (21) is arranged in the middle of the double-shell sealed furnace body (11), and a plurality of radiant tubes (4) are uniformly distributed above and below a chain plate (211) at the upper part of the material conveying device (21). The skid-mounted organic solid waste pyrolysis device is characterized in that a material distributor (5) is arranged on the upper surface of the chain plate (211) at the upper part close to the feeding hole (1), and a slag scraping device (31) is arranged below the chain plate (211). According to the invention, the materials are in the most efficient pyrolysis temperature field, the heating is sufficient, and the device has the characteristics of high pyrolysis quality, wide range of used materials, low particle size requirement, high pyrolysis efficiency and safe and reliable operation.

Description

technical field [0001] The invention is a skid-mounted organic solid waste pyrolysis device, relates to an organic solid waste pyrolysis device, and belongs to the field of environmental protection equipment. [0002] technical background [0003] Pyrolysis technology is one of the cutting-edge technologies for organic solid waste treatment at home and abroad. This technology uses a continuous process and a factory production method to make the organic pollutants in the organic solid waste pyrolyze or thermally condense to obtain the corresponding liquid phase oil, gas, coke and inorganic substances. At the same time, resources such as oil and combustible gas are recovered, realizing harmlessness and recycling. [0004] At present, pyrolysis treatment is more and more widely used in waste treatment, biomass, hazardous waste heat and other treatment. For example, expand pyrolysis and gasification to soil remediation, disposal of hazardous waste oily sludge, chromium-containi...

AI Technical Summary

Problems solved by technology

However, domestic pyrolysis technology started relatively late, and the development of the industry is not perfect

[0005] At present, the oily sludge pyrolysis treatment devices mainly include rotary type, spiral type, etc.; the problems of the rotary type are as follows: first, the problem of poor sealing in the continuous feeding state, and second, the problem of coking and dust removal caused by the large amount of dust ; while the spiral type is limited by the structure of the furnace body and the heating method, it is poor in material adaptability and thermal efficiency, especially when the material is stirred in the spiral, resulting in a large amount of dust at the outlet, which is likely to cause coking and blockage of pipe elbows and valves. Therefore, the frequency of equipment maintenance is high
