Problems solved by technology

Due to the difference in the nature of the raw materials, it is difficult to ensure the preparation of a stable liquid slurry that meets the requirements of the process when a variety of raw materials are blended. How to achieve different flow properties in the raw materials or a liquid slurry that cannot exist stably after blending The same-chamber gasification is one of the thorny difficulties faced by the development of gasification technology. In addition, when one of the raw materials in the raw material is a combustible gas, it is also very dangerous to routinely mix the combustible gas with a common gasification agent (such as oxygen) , therefore, it is necessary to develop a multi-channel atomizer and propose an operation method for gasification reaction using a multi-channel atomizer

Abstract

The invention discloses a multi-channel atomizer and a gasification reaction operation method. The multi-channel atomizer includes a multi-channel liquid slurry atomization structure and a cooling protection structure. The multi-channel liquid slurry atomization structure It includes M sleeves with different inner diameters and coaxially stacked from the inside to the outside in the order of inner diameters from small to large. The M sleeves have n+1 gas flow channels and n liquid flow channels, and n+1 The gas flow channel and the n liquid flow channels are arranged alternately from the inside to the outside according to the sequence of the gas flow channel and the liquid flow channel; the gasification reaction operation method includes: 1. Multi-channel atomizer Installation; 2. Atomization and dispersion of raw materials; 3. Gasification reaction of raw materials. The invention can realize the atomization of large-scale raw materials, not only can realize the purpose of simultaneous gasification reaction of various liquid slurries with different flow properties in one gasification reactor, but also can realize the gasification of two heterogeneous raw materials in one gasification reactor. The purpose of simultaneous gasification reaction in the reactor.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a multi-channel atomizer and a gasification reaction operation method. Background technique [0002] Wet entrained gasification technology is one of the more advanced clean coal technologies at present. This technology mostly uses coal as raw material to produce synthetic feed gas, which is further used to produce bulk products including synthetic ammonia, methanol, natural gas, and fuel oil. Basic chemicals have been widely used in many domestic enterprises. In recent years, with the further expansion of the production scale of enterprises, energy processing enterprises have gradually increased their demand for large-capacity wet gasification technology. About 2000t / day, when the processing capacity increases, the risk of atomizer wear and ablation increases greatly, which greatly limits the large-scale improvement of the processing capacity of a single s...
