Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment equipment, in particular to a thermal hydrolysis organic waste treatment equipment. Background Art

[0002] Organic waste refers to solid, liquid or gaseous organic items and substances generated in production, life and other activities that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned. According to the form, organic waste mainly includes organic solid waste, organic wastewater and organic waste gas. Organic waste is treated by thermal decomposition, generally using a circulating fluidized bed to treat organic waste.

[0003] With the development of economy and the improvement of residents' living standards, organic solid waste has had a serious impact on environmental sanitation. Therefore, people are actively exploring better ways to treat and dispose of organic solid waste.

[0004] The circulating fluidized bed is fluidized when the gas velocity is greater than the free settling velocity of the particles. The particles are carried out by the gas flow, and after the gas and solid are separated, the solid is circulated back to the fluidized bed formed in the bed. It has many uses in industry, such as catalytic cracking. The catalyst is fluidized and transported by heavy oil vapor in the riser, and the reaction occurs at the same time. The deactivated catalyst at the top of the riser is separated from the oil and gas and enters another fluidized reactor, where it is fluidized by air and regenerated. The regenerated catalyst is circulated back to the riser to form a catalytic cracking reactor consisting of a circulating fluidized bed.

[0005] When organic waste is subjected to thermal decomposition treatment, the organic waste to be thermally decomposed is introduced into the gasifier for incineration through the feeding structure. However, when the organic waste is introduced into the gasifier, no protective structure is set at the intersection with the gasifier. In this way, the heat inside the gasifier or the flame generated by the incineration may enter the feed structure from the feeding port, causing the organic waste to be transported inside the feed structure to be ignited.
