Problems solved by technology

[0003] The advantage of the single-nozzle direct-injection gasifier lies in its simple structure and control, and low cost. However, since the pressurized gasification process involves high temperature, high pressure, fluid flow under heterogeneous In the chemical reaction process, the production capacity of the single-nozzle gasifier is greatly limited, so it cannot meet the needs of large-scale development of the device
[0004] Due to the uneven distribution of the flame field in the multi-nozzle opposed gasifier, it is easy to cause ablation of the internal refractory material, which affects the service life of the refractory bricks, which will also seriously affect the production capacity of the gasifier

Abstract

The invention relates to a protrusion type partition reactor. The protrusion type partition reactor comprises a reaction chamber 17 and a cooling chamber 20, the reaction chamber 17 is communicated with the cooling chamber 20 through a slag port 18, and the reaction chamber 17 and the cooling chamber 20 have the joint central axis. Compared with an existing gasifier, the protrusion type partition reactor has the advantages of being large in coal feeding amount, high in gasification efficiency, long in service life of a refractory lining and the like. Synthesis gas produced by utilizing the protrusion type partition reactor can be used as chemical engineering raw material gas and fuel gas, can be used for preparing hydrogen and synchronizing liquid fuels and the like, and is extremely wide in application.

Description

【Technical field】 [0001] The invention belongs to the technical field of clean and efficient utilization of energy. More specifically, the present invention relates to a raised zoned reactor. 【Background technique】 [0002] Gasification technology using hydrocarbons as raw materials has been widely used in synthetic ammonia, synthetic methanol industry, power generation (IGCC), coal-to-oil and other technical fields. This reactor is used to produce syngas CO+H 2 Therefore, many scientific and technical personnel have developed various types of reactors. In the existing advanced entrained entrained gasification technology, the reactors used include coal water slurry gasifier, GSP, Shell pulverized coal gasifier, etc. At the same time, the reactor can be divided into a single-nozzle gasifier and a multi-nozzle gasifier according to the feeding method, furnace lining, number and arrangement of nozzles, and different gasifiers have their own advantages and disadvantages.
