[0001] The invention relates to the technical field of gas field ground processing equipment, in particular to a device for separating sulfur particles and liquid droplets in a high-sulfur gas field. Background Art

[0002] When processing gas containing sulfur particles from high-sulfur gas fields, sulfur particles are prone to deposition in the pipeline due to their presence. Therefore, the sulfur particles should be removed as much as possible while removing the droplets in the demister.

[0003] When the wire mesh demister is processing gas containing sulfur particles and droplets in high-sulfur gas fields, it is prone to clogging and requires manual flushing at irregular intervals. Production must be stopped before flushing, and automatic flushing is difficult to achieve. The folded plate demister has the characteristic of not being easily clogged, but as the operating time increases, the folded plate demister may also be clogged with sulfur particles. In order not to affect normal production work during flushing, it is very necessary to achieve automatic flushing of the folded plate demister without stopping production. Summary of the Invention

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] Example:

[0027] like Figure 1-3 As shown, the embodiment of the present invention provides a separation device for sulfur particles and droplets in high-sulfur gas fields, comprising an inlet section 1, a folding plate section 2, an outlet section 10, a sewage chamber 6, a water washing system 3, a top plate 9 and a base 8. The inlet section 1 is gradually expanded, the inlet section 1 is connected to the folding plate section 2, and each flow channel of the folding plate section 2 is provided with two arc-shaped baffles 22-1 and 22-2. A water washing system 3 is provided above the folding plate section 2. The water washing system 3 consists of a water inlet pipe 31, a telescopic hose 33, a water collecting pipe 32 and water washing pipes 34-1, 34-2, 34-3, 34-4, 34-5, the water inlet pipe 31 is fixed through the top plate 9 by the pipe clamp 35-1 to connect the telescopic hose 33, the water inlet pipe 31 above the top plate 9 is equipped with an induction switch 5-3, the telescopic hose 33 is connected to the water collecting pipe 32 through the pipe clamp 35-2, and the two ends of the water collecting pipe 32 are fixed in the tracks 4-1 and 4-2 at the upper end of the inlet and outlet of the folding plate section 2 by sliders 41-1 and 41-2. The tracks 4- 1, 4-2 are equipped with reciprocating drives 43-1, 43-2 at the front end, and the reciprocating drives 43-1, 43-2 are equipped with induction switches 5-1, 5-2. The bottom of the sliders 41-1, 41-2 is connected to the partitions 42-1, 42-2 that can just block a flow channel. The partitions 42-1, 42-2 pass through the tracks 4-1, 4-2. The water collecting pipe 32 is connected to several water washing pipes 34-1, 34-2, 34-3, 34-4, 34 -5, the water washing pipes 34-1, 34-2, 34-3, 34-4, and 34-5 do not enter the folding plate section 2 but are above the folding plate 21. The outlet section 10 is connected to the back of the folding plate section 2 and is tapered. The intelligent pressure difference sensor 7 is connected to the inlet section and the outlet section. The sewage chamber 6 is arranged in an arc shape below the inlet section 1 to the outlet section 10 of the device and is installed on a base 8 with a matching shape. The sewage pipe 61 is led out from the bottom of the sewage chamber 6 and passes through the base 8 horizontally.

[0028] When the device for separating sulfur particles and droplets in high-sulfur gas fields is working as a whole, the gas carrying droplets and sulfur particles passes from the inlet 11 through the inlet section 1 into the folded plate section 2. After the gas enters the folded plate section 2, the droplets and sulfur particles are removed in the folded plate section 2, and then enters the outlet section 10. All the settled droplets and sulfur particles fall into the sewage chamber 6 and are discharged through the sewage pipe 61.

[0029] When encountering the arc baffles 22-1, 22-2 or the bend of the folding plate 21 in the flow channel of the folding plate section 2, the liquid droplets and sulfur particles in the gas cannot change their movement direction in time with the change of the airflow direction due to their relatively large mass and inertia. They collide with the folding plate 21 and settle, thereby achieving the effect of separating the liquid droplets and sulfur particles in the gas. After the airflow collides with the arc baffles 22-1, 22-2, the liquid droplets and sulfur particles carried in the gas are further separated. The settled liquid droplets and sulfur particles slide down from the arc baffles 22-1, 22-2 or the folding plate 21 into the sewage chamber 6 and are discharged from the device through the sewage pipe 61.

[0030] Sulfur particles are easily deposited and agglomerated at the collision point between the arc-shaped baffles 22-1, 22-2 and the windward surface of the folding plate 21. The demister may have the problem of blockage of the flow channel when it is operated for a long time. When the thickness of the sulfur particle deposition on the windward surface of the arc-shaped baffles 22-1, 22-2 and the folding plate 21 continues to increase, the pressure difference between the inlet and outlet also gradually increases. When the pressure difference increases to a certain value, the intelligent pressure difference sensor 7 sends a signal. The signal receiving end is the induction switch 5-3 of the water inlet pipe 31 and the induction switches 5-1, 5-2 installed on the reciprocating drivers 43-1, 43-2. The induction switches 5-1, 5-2, and 5-3 that receive the signal are turned on, and water enters the telescopic hose 33 through the water inlet pipe 31 and reaches the water collecting pipe 32 with the same shape as the folding plate 21, and finally flows out from the water washing pipes 34-1, 34-2, 34-3, 34-4, and 34-5, thereby achieving a flushing effect without dead angles. The flushed droplets and sulfur particles fall into the sewage chamber 6 and are discharged from the sewage pipe 61.

[0031] When the value of the intelligent pressure difference sensor 7 does not reach the value of turning on the sensing switches 5-1, 5-2, and 5-3, the sliders 41-1, 41-2, the partitions 42-1, 42-2, and the water collection pipe 32 are located at the front end of the tracks 4-1 and 4-2, on the outside of the boundary fold 21. When the value of the intelligent pressure difference sensor 7 reaches the value of turning on the sensing switches 5-1, 5-2, and 5-3, the sliders 41-1, 41-2 move along the tracks 4-1 and 4-2 with the partitions 42-1, 42-2 and the water collection pipe 32. The function of the partitions 42-1 and 42-2 is to block the airflow to prevent the airflow from carrying the droplets again during flushing. When the pressure difference drops below the value of turning on the sensing switches 5-1, 5-2, and 5-3, the reciprocating drivers 43-1 and 43-2 drive the sliders 41-1, 41-2 back to the front end of the tracks 4-1 and 4-2.

[0032] The inlet section 1 is gradually expanding, and the pressure increases, while the outlet section is gradually contracting, and the pressure decreases, which has a certain balancing effect on the pressure difference between the inlet and the outlet.

[0033] In summary, the embodiments of the present invention provide a device for separating sulfur particles and droplets in high-sulfur gas fields, which can remove sulfur particles and droplets carried by the gas in high-sulfur gas fields. If the accumulation of sulfur particles reaches a certain value, automatic flushing without dead angles can be achieved without stopping production, while avoiding secondary entrainment of droplets by the airflow during flushing.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
