Coal synthesis gas slurry bed reactor for producing oxygenated fuel

Abstract

Provided is a coal synthesis gas slurry bed reactor for producing oxygenated fuel. On the upper portion of the reactor, a multilayer grate-type gas and liquid separator is arranged, a high-temperature hot water outlet is connected and communicated with a gas-phase product liquid-gas surface heat exchanger and a liquid-phase product liquid-liquid surface heat exchanger in series, a gas-solid mixture outlet is formed and communicated with a gas-phase product outlet of the gas-phase product liquid-gas surface exchanger through a gas-phase product gas-solid filter for discharging, and a liquid-solid mixture outlet is formed and communicated with a liquid-phase product outlet of the liquid-phase product liquid-liquid surface heat exchanger through a liquid-phase product liquid-solid filter for discharging. In the middle of the reactor, a reaction heat releasing and heat absorbing coil pipe is arranged. On a lower shell of the reactor, an upper layer reaction gas inlet, a middle layer reaction gas inlet and a lower layer reaction gas inlet are formed tangentially. According to the coal synthesis gas slurry bed reactor, an internal device is removed, the space is enlarged by 15%-30%, the probability of forming large bubbles in the rising process of small bubbles is reduced, the effective reaction contact area is enlarged, and the reaction efficiency of the slurry bed reactor is improved.

Description

technical field [0001] The invention relates to a reactor for producing oxygen-containing fuel in a slurry bed of coal synthesis gas, in particular to a reactor for producing oxygen-containing fuel in an external swirling slurry bed of coal synthesis gas. Background technique [0002] The gas-liquid-solid three-phase slurry bed reactor has the characteristics of simple structure, uniform dispersion effect, and excellent transfer performance. The huge development potential of state-bed reactors in coal chemical industry and other fields. [0003] There are still many problems to be solved urgently in the process of industrialization of the slurry bed reactor, the main reason is that the enlargement of the slurry bed reactor is very difficult. Publication No. CN1593740A is an invention patent of "high-efficiency slurry bed reactor", in which distribution plates, heating plates, and inner sleeve components are arranged in the reactor; ZL200910209536.3 discloses a slurry bed re...

[0003] There are still many problems to be solved urgently in the process of industrialization of slurry bed reactor, the main reason is that the enlargement of slurry bed reactor is very difficult

Publication No. CN1593740A is an invention patent of "high-efficiency slurry bed reactor", in which distribution plates, heating plates, and inner sleeve components are arranged in the reactor; ZL200910209536.3 discloses a slurry bed reactor, Built-in filter components are used; ZL201010125941.X discloses a slurry bed reactor, which uses a built-in cyclone and heat-absorbing coil; the main problems of slurry bed reactor amplification: distributor clogging, countercurrent, catalyst and temperature distribution Inhomogeneity, etc., the increase in diameter will change the fluid flow characteristics inside the reactor, thereby affecting the quality and heat transfer; and after the diameter increases, it is difficult to remove the heat inside the reactor in time, and the temperature distribution in the reactor is uneven, which is not conducive to maintaining Reaction speed and improved catalyst life, the existing slurry bed reactor still has bias flow, channel flow and blockage of bed parts, and fails to consider the gas-solid and gas-liquid separation factors of the system. In view of the above problems, this patent proposes a coal synthesis gas Oxygenated fuel reactor with external swirling slurry bed
