Description

Technical fields:

[0001] This utility model belongs to the field of high-temperature raw oil and gas treatment technology, and more specifically relates to a mechanical unblocking device for the extraction of high-temperature raw oil and gas. Background technology:

[0002] High-temperature oil and gas in dust removal devices in pyrolysis and purification fields such as low-temperature coal pyrolysis and coal gas stations are prone to condensation and dust accumulation. Especially at the coal gas outlet, it is more likely to be blocked by oil and dust, and cannot be cleaned online, which cannot guarantee long-term operation, poses certain safety hazards, and affects the continuous operation of production and economic benefits.

[0003] Our company's prior patent application, National Utility Model Patent No. 202323458593.X, discloses a cross-shaped exhaust device for high-temperature raw oil gas, which can clean the high-temperature raw oil gas adhering to the pipes in the horizontal and vertical directions, avoiding the generation of dead corners and preventing the adhering high-temperature raw oil gas from clogging the air inlet of the dust collector or furnace body or the air outlet of the rotary kiln.

[0004] The four-way exhaust principle addresses the issue of high-temperature oil and gas in the rotary kiln failing to exit when high-temperature dry distillation gas encounters a malfunction in the subsequent purification workshop. This presents several problems: First, operators are prone to operational errors, requiring production shutdowns for maintenance, which seriously threatens the long-term continuity and safety of production. Second, vertical dust collectors are susceptible to malfunction due to gravity, causing pipe blockages and necessitating production shutdowns for maintenance, again seriously threatening production safety. Conventional methods cannot achieve precise oxygen sealing, and pressure fluctuations are prone to occur during the cleaning process, causing disturbances to subsequent systems. Utility Model Content:

[0005] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a mechanical unblocking device for high-temperature crude oil and gas extraction.

[0006] The first technical problem to be solved is that the high-temperature oil and gas in the rotary kiln cannot be discharged when the high-temperature dry distillation gas encounters a malfunction in the subsequent purification workshop. This has the following problems: First, operators are prone to misoperation, requiring production to be stopped for maintenance, which seriously threatens the long-term continuity and safety of production; Second, the vertical dust collector is prone to malfunction due to gravity, causing pipeline blockage, requiring production to be stopped for maintenance, which seriously threatens production safety.

[0007] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the mechanical unblocking device for high-temperature raw oil and gas extraction includes a three-way pipe, wherein the three-way pipe includes a main pipe and a branch pipe, and the branch pipe is connected to the side wall of the main pipe.

[0008] Along the tangential direction of the side wall of the high-temperature raw oil and gas outlet pipe, the branch pipe is set at a 45-degree angle to the high-temperature raw oil and gas outlet pipe.

[0009] One end of the main pipe is equipped with a mechanical unblocking structure, and the other end is connected to the air inlet of the dust collector or furnace body.

[0010] The mechanical unblocking structure includes a valve body, inside which a valve stem, a tensioner, and a scraper are installed, and on the outside of the valve body is a drive unit that drives the valve stem to reciprocate.

[0011] Furthermore, the high-temperature raw oil and gas outlet pipe is arranged in a vertical direction.

[0012] Furthermore, the high-temperature raw oil and gas outlet pipe is the outlet pipe of a rotary kiln, circulating fluidized bed, moving bed particle dust collector, fixed bed particle dust collector, high-temperature cyclone dust collector, or gravity dust collector.

[0013] Furthermore, the drive unit is configured as a hydraulic cylinder or a pneumatic cylinder, and the drive unit drives the valve stem to reciprocate along the main shaft.

[0014] Furthermore, the scraper can reciprocate along the main shaft and extend to the dust collector or furnace body by pushing and pulling the valve stem.

[0015] Furthermore, the scraper engages with the inner wall of the main pipe.

[0016] The beneficial effects of this utility model are:

[0017] One advantage of this invention is that it provides a mechanical unblocking device for unidirectional cleaning of high-temperature grease and gas, which can clean the high-temperature grease and gas adhering to the pipeline, avoid dead corners, and effectively reduce the equipment failure rate.

[0018] Along the tangent direction of the side wall of the high-temperature raw oil and gas outlet pipe, the branch pipe is set at a 45-degree angle to the high-temperature raw oil and gas outlet pipe; one end of the main pipe is equipped with a mechanical unblocking structure, and the other end is connected to the air inlet of the dust collector or furnace body to prevent pipe blockage caused by personnel misoperation, prevent the scraper from being blocked by gravity, and achieve safe, continuous and stable long-term operation of production.

[0019] One advantage of this invention is that it provides a mechanical cleaning device for high-temperature raw oil and gas. The scraper can reciprocate through the push and pull of the valve stem and extend into the quench tower or subsequent purification section, which can prevent condensed oil and gas from clogging the outlet.

[0024] The specific embodiment of this utility model: The mechanical unblocking device for high-temperature crude oil and gas extraction includes a three-way pipe; the improvement of this utility model is as follows:

[0025] The tee pipe includes a main pipe 7 and a branch pipe 8, with the branch pipe 8 connected to the side wall of the main pipe 7.

[0026] Along the tangent direction of the side wall of the high-temperature raw oil and gas outlet pipe 9, the branch pipe 8 is set at a 45-degree angle to the high-temperature raw oil and gas outlet pipe 9.

[0027] Among them, the high-temperature raw oil and gas outlet pipe 9 is the outlet pipe of rotary kiln, circulating fluidized bed, moving bed particle dust collector, fixed bed particle dust collector, high-temperature cyclone dust collector, and gravity dust collector. The high-temperature raw oil and gas outlet pipe 9 is arranged in the vertical direction.

[0028] One end of the main pipe 7 is equipped with a mechanical unblocking structure, and the other end is connected to the air inlet of the dust collector or the furnace body 10.

[0029] The mechanical unblocking structure includes a valve body 2, inside which are a valve stem 3, a tensioner 5, and a scraper 1. On the outside of the valve body 2 is a drive unit 6 for driving the valve stem 3 to reciprocate.

[0030] In a preferred embodiment of this utility model: the drive unit 6 is configured as a hydraulic cylinder or a pneumatic cylinder, and the drive unit 6 drives the valve stem 3 to reciprocate along the axis of the main pipe 7. The scraper 1 can reciprocate along the axis of the main pipe 7 and extend to the dust collector or furnace body 10 by the push and pull of the valve stem 3. The scraper 1 is fitted with the inner wall of the main pipe 7.

[0031] It should be noted that this utility model is a mechanical unblocking device for the extraction of high-temperature crude oil and gas. In specific operation...

[0032] 1. Name “Drive Unit 6” as Cylinder #1 and control it by Operating Lever #1;

[0033] 2. Check that the hydraulic hose connections are normal. Confirm the position markings on push rod #1, ensuring that all pistons are outside the T-junction structure; the hydraulic cylinder should be fully retracted into the cylinder.

[0034] 3. Power on the hydraulic station or air source and check that the oil pressure is normal and does not exceed the upper limit.

[0035] 4. Under normal circumstances, operate cylinder #1 to complete the "pull out-retract" action.

[0036] 5. During operation, two people should work together: one person pushes the #1 operating lever outwards, while the other person simultaneously checks whether the hydraulic rod of the #1 cylinder is extending normally. Under normal circumstances, it should extend at a uniform speed. Continue pushing until it can no longer be pushed, then retract it.

[0037] 6. After confirming that the cylinder has been retracted into place, the hydraulic station or cylinder is powered off, completing one "unblocking operation".

[0038] 7. The scraper 1 cooperates with the inner wall of the main pipe 7, and the reciprocating scraper 1 cleans the high-temperature grease and gas adhering to the inner wall of the main pipe 7.

[0039] In particular: the scraper 1 can reciprocate and extend into the dust collector or furnace body 10 by pushing and pulling the valve stem 3. This can prevent the attached high-temperature raw oil gas from clogging the outlet of the high-temperature raw oil gas outlet pipe 9, and can clean the attached high-temperature raw oil gas in the pipe, avoiding the generation of dead corners and effectively reducing the equipment failure rate.

[0040] Along the tangential direction of the side wall of the high-temperature raw oil and gas outlet pipe 9, the high-temperature raw oil and gas can be cut out in a swirling manner to avoid pipe blockage. The branch pipe 8 is set at a 45-degree angle to the high-temperature raw oil and gas outlet pipe 9 to prevent the scraper 1 from being blocked by gravity, thus achieving safe, continuous and stable long-term operation of production.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
