Description

Technical Field

[0001] The invention relates to the technical field of sulfur-containing gathering and transportation, and in particular to a wet gas pressurization pretreatment device for a high-sulfur gas field. Background Art

[0002] Conventional natural gas boosting usually uses a booster after gravity separation, and is equipped with a gravity separator for primary separation. An interstage or final stage separator is installed inside the booster unit, and high-efficiency oil removal is not considered. The mid-body venting adopts high-point discharge, and no centralized venting facilities are set up.

[0003] In the existing technology, sulfur is easily precipitated during the middle and late stages of development of high-sulfur gas fields, resulting in sulfur blockage of pipelines and equipment. The use of conventional gravity separation facilities cannot solve the sulfur blockage problem. At the same time, the use of gas-liquid mixed transmission technology in high-sulfur gas fields will cause water flooding to the horizontal filtration separation, reducing the separation effect of the filter separator.

[0006] Specifically, the diameter of the upper end of the cyclone tube is greater than the diameter of the lower end of the cyclone tube, and the outer diameter of the spiral guide plate gradually decreases from top to bottom.

[0007] Specifically, the bracket includes a connecting plate fixed to the lower end of the vortex tube, a sliding sleeve is fixed on the connecting plate, the lower end of the lower rotating shaft is located in the sliding sleeve, the lower rotating shaft can rotate in the sliding sleeve, and the lower rotating shaft can slide in the sliding sleeve along its axial direction.

[0011] 2. The rotation of the spiral guide plate can increase the centrifugal force generated by the solid phase, liquid phase and part of the gas phase during the downward rotation in the cyclone tube, further improving the dispersion efficiency of the gas phase.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figure 1-Figure 8 As shown, a high-sulfur gas field wet gas pressurization pretreatment device includes an inlet separator 200, the upper end of the inlet separator 200 is fixedly connected to a cyclone separator 100, the lower end of the inlet separator 200 below the cyclone separator 100 is fixedly connected to a solid phase outlet pipe 400, the upper end of the inlet separator 200 is fixedly connected to a gas phase outlet pipe 500, and the lower end of the inlet separator 200 below the gas phase outlet pipe 500 is fixedly connected to a liquid phase outlet pipe 600. A plurality of baffles 300 are staggeredly installed in the inlet separator 200 on the right side of the cyclone separator 100, and the gas phase outlet pipe 500 and the liquid phase outlet pipe 600 are located on the right side of the plurality of baffles 300.

[0025] The gas outlet pipe 2 and the gas phase outlet pipe 500 of the cyclone separator 100 are connected to the additional unit.

[0026] The cyclone separator 100 includes a tank body 1, the lower end of the tank body 1 is connected to the interior of the inlet separator 200, the outlet pipe 2 is fixed at the upper end of the tank body 1 and connected to the interior of the tank body 1, a plurality of cyclone tubes 4 are fixed in the tank body 1, the cyclone tubes 4 are connected to the inlet pipe 3 fixed on the tank body 1 through the diverter pipe 5, the diverter pipe 5 is arranged along the tangential direction of the cyclone tube 4 connected thereto, the upper end of the cyclone tube 4 is fixedly connected to a connecting pipe 6, the connecting pipe 6 is connected to the tank body 1, and the lower end of the cyclone tube 4 is connected to the tank body 1.

[0027] The diameter of the upper end of the cyclone tube 4 is greater than the diameter of the lower end of the cyclone tube 4 .

[0028] An upper rotating shaft 7 is concentrically arranged in the cyclone tube 4, and a spiral guide plate 8 is fixed on the outer side of the upper rotating shaft 7, and the outer diameter of the spiral guide plate 8 gradually decreases from top to bottom. A lower rotating shaft 11 is concentrically arranged below the upper rotating shaft 7, and a turbine blade 12 is fixed on the outer side of the lower rotating shaft 11. The upper part of the turbine blade 12 is located in the lower end of the cyclone tube 4, and the lower rotating shaft 11 is movably connected with a bracket fixed at the lower end of the cyclone tube 4. Specifically, the bracket includes a connecting plate 16 fixed at the lower end of the cyclone tube 4, and a sliding sleeve 17 is fixed on the connecting plate 16. The lower end of the lower rotating shaft 11 is located in the sliding sleeve 17, and the lower rotating shaft 11 can rotate in the sliding sleeve 17, and the lower rotating shaft 11 can slide in the sliding sleeve 17 along its axial direction.

[0029] A vertical square hole 9 is formed in the lower end of the upper rotating shaft 7, and a square rod 10 is fixed to the upper end of the lower rotating shaft 11. The square rod 10 is slidably inserted in the square hole 9, and the square rod 10 is elastically connected to the upper rotating shaft 7. Specifically, the upper end of the square rod 10 is fixedly connected to the lower end of the tension spring 13, and the upper end of the tension spring 13 is fixedly connected to the upper hole wall of the square hole 9.

[0030] A plurality of grooves 14 are provided in the vertical direction on both opposite sides of the square rod 10 , and a plurality of spring pins 15 corresponding to the grooves 14 are installed in the square hole 9 , and the free ends of the spring pins 15 are snap-fitted with the grooves 14 on one side thereof.

[0031] When in use, the wet gas from the sulfur-containing gas field enters each cyclone tube 4 through the air inlet pipe 3 and the shunt pipe 5. Since the shunt pipe 5 is arranged along the tangential direction of the cyclone tube 4 connected thereto and a spiral guide plate 8 is arranged on the upper rotating shaft 7, the wet gas from the sulfur-containing gas field enters the cyclone tube 4 and rotates downward. Under the action of centrifugal force, the liquid phase and solid phase of the wet gas from the sulfur-containing gas field rotating downward approach the inner wall of the cyclone tube 4, and part of the gas phase of the wet gas from the sulfur-containing gas field is discharged into the tank body 1 through the connecting pipe 6 and then discharged through the air outlet pipe 2, and the rest of the gas phase of the wet gas from the sulfur-containing gas field moves downward with the solid phase and the liquid phase.

[0032] When the liquid phase, solid phase and part of the gas phase of the wet gas in the sour gas field pass through the turbine blades 12, since the diameter of the lower end of the swirl tube 4 is smaller than the diameter of the upper end of the spiral tube, the pressure of the liquid phase, solid phase and part of the gas phase of the wet gas in the sour gas field flowing in the lower end of the swirl tube 4 increases, thereby driving the turbine blades 12 to rotate. The turbine blades 12 can block and disturb the liquid phase, solid phase and part of the gas phase of the wet gas in the sour gas field, further improving the efficiency of the gas phase dissipation in the liquid phase and solid phase.

[0033] When the turbine blades 12 rotate, they drive the lower rotating shaft 11 to rotate. The lower rotating shaft 11 drives the upper rotating shaft 7 and the spiral guide plate 8 to rotate through the square rod 10. During the rotation of the spiral guide plate 8, the centrifugal force of the sour gas field wet gas spiraling downward in the cyclone tube 4 can be increased, thereby further improving the efficiency of dissipation of the gas phase in the sour gas field wet gas.

[0034] After the solid phase, liquid phase and part of the gas phase of the wet gas in the sulfur-containing gas field are blocked by the rotating turbine blades 12 during the downward rotation, the turbine blades 12 drive the lower shaft 11 to move downward, the tension spring 13 is stretched, and the upper part of the turbine blades 12 slides out of the lower end of the cyclone tube 4, so that the solid phase, liquid phase and part of the gas phase rotating downward can be effectively discharged.

[0035] When the square rod 10 slides downward, the spring pin 15 will be squeezed intermittently, and the spring pin 15 can intermittently knock the square rod 10, which can make the square rod 10, the lower shaft 11 and the turbine blades 12 vibrate, thereby shaking off the solid phase on the turbine blades 12, avoiding the solid phase adhering to the turbine blades 12 and causing jamming.

[0036] After the solid phase, liquid phase and part of the gas phase of the wet gas in the sulfur-containing gas field enter the inlet separator 200, the solid phase and the liquid phase gather at the bottom of the inlet separator 200, and the solid phase is deposited in the inlet separator 200, and the solid phase can be regularly discharged from the solid phase outlet pipe 400. The liquid phase can be regularly discharged from the liquid phase outlet pipe 600.

[0037] The gas phase entering the inlet separator 200 is deflected by the baffle plate 300, and the mist droplets in the gas phase in the inlet separator 200 condense into liquid droplets on the baffle plate 300 and drip into the inlet separator 200. Arranging a plurality of baffle plates 300 can reduce the liquid phase content in the gas phase discharged from the inlet separator 200.

[0038] The gas phase discharged from the gas outlet pipe 2 and the gas phase outlet pipe 500 is increased by the additional unit and then output.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
