Device for continuously separating gas hydrate

Abstract

The invention discloses a device for continuously separating gas hydrate, which comprises an upper box body and a lower box body, wherein the upper box body is a gas collecting cavity (7), the upper end of the upper box body is provided with a separated gas outlet (10), a safety valve port (16) and a pressure meter port (17), and the lower part of the upper box body is provided with a silk screen mist eliminator (6); the lower box body is shaped as a cuboid, the upper part of the lower box body is provided with a hydrate slurry inlet (1), the tail end of the hydrate slurry inlet (1) is provided with a flow equalizing plate (2) in a vertical direction, the bottom end of the flow equalizing plate (2) is provided with a sieve plate (3), the sieve plate (3) is alternatively connected with a drainage plate (4) to form a separating channel; a water collecting cavity (8) is arranged between the separation channel and the lower box body, and the lower part of the separation channel is provided with a separated water outlet (11); and the lower end of the separation channel is connected with a hydrate storing cavity (9), and the bottom end of the hydrate storing cavity (9) is provided with a hydrate outlet. The invention has the advantages of simple structure, small occupation area and convenience for maintenance.

Description

technical field [0001] The invention belongs to the field of gas, liquid and solid separation devices, in particular to a device for continuous separation of other hydrates. Background technique [0002] At present, using the unique chemical and physical characteristics of hydrates can develop a series of high-tech, involving water resources, environmental protection, climate, oil and gas storage and transportation, petrochemical, biopharmaceutical and many other fields. Typical examples include the hydrate desalination of seawater to make up for the shortage of fresh water resources; the hydrate method permanently reduces the greenhouse gas CO 2 Storage in the seabed to improve the global climate environment; storage, transportation, and distribution of natural gas in the form of hydrate; hydrate separation of low-boiling gas mixtures (such as ethylene cracking gas, various refinery dry gas and natural gas), etc. An important link in the application of these technologies i...

Problems solved by technology

Since most of the gravity sedimentation separation equipment has the disadvantages of large volume, complex structure, long processing time, poor separation effect, and discontinuous work, the use of various separation equipment in the process will inevitably increase investment costs, operation management and maintenance costs.
