A Fischer-Tropsch Synthesis Slurry Bed Reactor Containing Shell and Tube Heat Exchangers

Abstract

The invention relates to the field of chemical equipment, and in particular, relates to a multitubular heat exchanger and a Fischer-Tropsch synthetic slurry bed reactor, wherein the multitubular heatexchanger includes a storage structure, a cooling structure, a diversion structure, a holding structure, a first drive structure, a cam, a second drive structure, a waste heat utilization structure and an adjustment structure; the cooling structure for heat transfer is arranged inside the holding structure; the side wall of the holding structure is provided with the second drive structure, the second drive structure is connected to the waste heat utilization structure inside the storage structure; the storage structure for storing a Fischer-Tropsch synthetic fuel is enclosed between the wasteheat utilization structure and the holding structure. The second drive structure cooperates with the use of the waste heat utilization structure to promote the circulation of gas or liquid inside theholding structure, the internal pressure of a drainage hole for discharging the Fischer-Tropsch synthetic fuel is increased, then the transportation of the Fischer-Tropsch synthetic fuel is more efficient, the cooling structure and the waste heat utilization structure cooperate with the use of the storage structure, and then the waste heat in the Fischer-Tropsch synthetic fuel is rationally utilized.

Description

Technical field[0001]The invention relates to the field of chemical equipment, in particular to a Fischer-Tropsch synthesis slurry-bed reactor containing a tubular heat exchanger.Background technique[0002]With the continuous development of science and technology, the production of liquid fuels from coal is an effective way to alleviate the shortage of petroleum resources. Fischer-Tropsch synthesis is one of the main methods; Fischer-Tropsch synthesis uses coal or natural gas as raw materials for synthesis The method for producing hydrocarbon or alcohol liquid fuel under the catalysis of iron or cobalt at a temperature of 400~500℃ with synthesis gas, tubular heat exchanger and Fischer-Tropsch synthesis slurry bed The reactor is an important equipment for Fischer-Tropsch synthesis technology.[0003]However, a Fischer-Tropsch synthesis slurry bed reactor containing a tubular heat exchanger mentioned in the patent application number 201520939585.3 has low utilization efficiency of waste ...
