Abstract
The invention discloses a filter internal component for a slurry bed reactor, in order to solve the problems of a great impact on surrounding flow field, poor filtration effect, easy blocking, high gas holdup around the filter pipe and easy local pipe drying when an existing filter pipe is used for liquid-solid separation of the slurry bed reactor. The filter internal component comprises a filter tube bundle, an outer circulation cup and an internal circulation cup. The outer circulation cup and the inner circulation cup form an annular separation space, and the filter tube bundle is arranged in the annular separation space formed by the outer circulation cup and the inner circulation cup. The filter tube bundle is composed of a collection tube, an upper annular filter tube, a lower annular filter tube, an upper straight filter tube and a lower straight tube filter tube. The collection tube is a combination of a section of straight tube and an annular tube; the upper annular filter tube and the lower annular filter tube are circular tubes, the upper straight filter tube and the lower straight filter tube are straight tubes; the annular tubes and straight tubes are communicated; and the collection tube is located in the middle of the filter tube bundle.
Description
technical field [0001] The invention relates to a device for separating solid particles from liquid products, which can realize the continuous separation of liquid products and solid particles, in particular to a filter internal component of a slurry bed reactor. Background technique [0002] Slurry bed reactors are widely used in chemical, petrochemical, biochemical and other fields due to their uniform dispersion effect, good transfer performance, and convenient operation. Especially in recent years, slurry bed reactors have shown great development potential compared with fixed bed reactors in Fischer-Tropsch synthesis and methanol synthesis from natural gas, and have accumulated experience in the promotion and use of them in chemical, petrochemical, biochemical and other fields. rich experience. [0003] In the Fischer-Tropsch reaction process using a slurry bed reactor, the slurry bed reactor mainly contains gaseous synthesis gas (including carbon monoxide and hydrogen)...
