Natural gas purifying device

Abstract

The invention relates to a natural gas purifying device which has a solid, semi-solid and liquid paraffin removing function. A shell is divided into a natural gas collecting chamber, a natural gas feed chamber, a heating chamber and a slag collecting chamber from top to bottom by an upper partition plate, a middle partition plate and a lower partition plate. A natural gas exhaust outlet is reserved at the top of the natural gas collecting chamber. A natural gas inlet is reserved on the upper portion of one side of the natural gas feed chamber while a clearing port is reserved on the lower portion of the side of the natural gas feed chamber. A heating gas inlet is reserved on the upper portion of one side of the heating chamber, and a heating gas outlet is reserved on the lower portion of the side of the heating chamber. A slag outlet and a valve are arranged at the bottom of the slag collecting chamber, and a liquid-level controller is arranged on one side of the slag collecting chamber. An overflow pipe of a cyclone separating pipe extends into the natural gas collecting chamber upwards, a gas inlet of the cyclone separating pipe is reserved in the natural gas feed chamber, a cylindrical section and a conical section of the cyclone separating pipe are located in the heating chamber, and an underflow pipe of the cyclone separating pipe extends into the slag collecting chamber downwards. The natural gas collecting chamber is communicated with the slag collecting chamber by a return pipe. By the natural gas purifying device, the problem that separating equipment is jammed by impurities such as paraffin in a paraffin removing process for natural gas, and continuous separation of the impurities such as the paraffin in the natural gas is realized.

Description

technical field [0001] The invention relates to the technical field of natural gas purification, in particular to a natural gas purification device with the function of removing solid, semi-solid and liquid paraffin. Background technique [0002] A natural gas purification device is a device that separates solids and liquids in natural gas. Patent 201120125520.7 combines the inlet and intake chambers that produce inertial pre-separation, the direct-flow multi-pipes that produce centrifugal separation, the exhaust chamber that produces gravity sedimentation, and the mist trap that produces coalescence and separation to separate fine droplets in natural gas. Patent 03134160.8 directly utilizes its pressure energy, or expansion refrigeration of refrigerators, or methanol instillation and ammonia compression refrigeration system refrigeration, or methods such as methanol instillation to dehydrate natural gas and recover liquid hydrocarbons in natural gas. Patent 01138807.2 incl...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the patent of the present invention is: in order to overcome the technical problem that the existing natural gas purification device cannot separate solid paraffin, the patent of the present invention provides a method for separating solid, semi-solid and liquid paraffin entrained in natural gas, and can also separate Other natural gas purification devices that separate dust and water together. In addition, the cyclone separation tube can continuously discharge wax, so that the invention can continuously dewax, and the installation, commissioning, operation and maintenance are convenient
