Multi-purpose gathering combustion type rotary furnace

Abstract

The invention discloses a multi-purpose gathering combustion type rotary furnace. The multi-purpose gathering combustion type rotary furnace comprises a furnace base. An outer furnace barrel and an inner furnace barrel are installed on the furnace base in a rotating mode and are synchronous. The two ends of the outer furnace barrel are connected with a feeding and discharging end base and a gathering combustion end base in a dynamic sealing mode correspondingly. One end of the inner furnace barrel is connected with a sealed feeding device. A combustion isolation body which stretches into the inner furnace barrel is arranged on the gathering combustion end base, a gathering combustion channel is formed in the portion, corresponding to a material gathering region, of the combustion isolationbody, and a slag falling opening is formed in the gathering combustion end base. A combustion supporting air supply pipe is arranged in the gathering combustion channel, and an annular flame retardant layer is arranged in the inner furnace barrel. A gas resistance device is arranged between the gathering combustion end base and the portion, located outside the material gathering region, of the inner furnace barrel, and the inner furnace barrel is connected with a gas supplement device. According to the multi-purpose gathering combustion type rotary furnace, the combustion heat can preheat rawmaterials, organic matter components can be precipitated and subjected to thermal decomposition to be gasified, the air flow enables the gaseous combustible materials to arrive at the gathering combustion channel and to be gathered, the centralized and powerful combustion is easily formed, and therefore the residual combustible materials inside the raw materials can be prompted to be sufficientlyburnt, and the number of hazardous substances in the tail gas can also be obviously reduced.

Description

technical field [0001] The invention relates to a boiler, in particular to a multipurpose gathering combustion type rotary kiln. Background technique [0002] Crude oil will pollute the soil in the process of exploration, mining, transportation and storage. The physical and chemical properties of oil-bearing soil will change due to the presence of crude oil, and it will cause adverse effects on the human living environment on multiple levels through the pollution of groundwater and the transfer of pollution. coercion. The existence of oily soil not only affects the environment and restricts economic development, but also makes it difficult to reuse crude oil resources in the soil. [0003] Industrial tail waste refers to the waste generated in the industrial production process, such as the tail dust filtered by the bag filter and the dried sludge of the sewage treatment plant. Based on the combustion technology of many boilers at present, the tail dust still contains a lar...

Problems solved by technology

These wastes contain a large number of bacterial viruses, and have certain characteristics of space pollution, acute virus infection and latent infection. If management is not strengthened and discarded at will, it is easy to cause the spread of diseases and seriously endanger people's physical and mental health.

Combustible components account for 92% of the total weight of medical waste. At present, high-temperature incineration is the mainstream method to treat medical waste, but there are few incineration methods that can completely burn it and reduce secondary pollution.
