Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a petrochemical impurity filtration device. Background Technology

[0002] In the petrochemical industry, a large amount of associated petroleum gas is generated during crude oil processing. This associated petroleum gas often contains various impurities. If water droplets and water vapor in the gas are not effectively separated and filtered, they will cause many problems for subsequent processing technology and equipment.

[0003] Traditional petrochemical impurity filtration equipment, when processing associated petroleum gas, suffers from poor gas-liquid separation efficiency and uniformity in existing gas-liquid separation devices. Ordinary separation structures struggle to evenly disperse the rising airflow on its surface, resulting in airflow concentration in localized areas and insufficient gas-liquid contact. Consequently, a large number of water droplets and water vapor cannot be effectively separated from the gas, thus affecting the purity of the subsequent gas. Therefore, this application provides a petrochemical impurity filtration device to meet this requirement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a petrochemical impurity filtration device to address the issues of poor efficiency and uniformity of existing gas-liquid separation devices, the inability of ordinary separation structures to evenly disperse rising airflow, the tendency of airflow to concentrate in local areas, insufficient gas-liquid contact, and the difficulty in separating a large number of water droplets and water vapor from the gas, which affects the purity of the subsequent gas.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A petrochemical impurity filtration device includes a tank, the inner wall of which is equipped with a filter assembly for filtering gaseous impurities in petroleum.

[0007] The filter assembly includes a feed pipe connected to one side of the tank. An exhaust pipe is connected to the top of the tank. Several separation plates are slidably arranged on the inner wall of the tank. Connecting plates are fixedly arranged on both sides of the separation plates. The connecting plates slide against the inner wall of the tank. Several separation holes are opened on the separation plates. A baffle is fixedly arranged on the inner wall of the tank on one side of the feed pipe. A defoaming block is fixedly arranged at one end of the exhaust pipe near the tank. A liquid level controller pipe is connected to the side of the tank away from the feed pipe.

[0008] Preferably, the inner wall of the tank is further equipped with a shaking component to shake the water droplets condensed on the surface of the separation plate. The shaking component includes a fixed block, and several fixed blocks are fixedly arranged on the inner wall of the tank. The inner wall of the fixed block is provided with a sliding groove, and a spring is fixedly arranged on the inner wall of the sliding groove. One end of the spring is fixed to the side near the sliding plate.

[0009] Preferably, the demister block includes a housing, which is fixedly disposed on the inner wall of the exhaust pipe. A support structure is fixedly disposed on the inner wall of the housing, and the support structure bracket is provided with a plurality of wire meshes.

[0010] Preferably, the support structure is arranged in a vertical direction.

[0011] Preferably, the diameter of the filter holes in the wire mesh is smaller than that of the separation holes.

[0012] Preferably, the separation plate is cone-shaped.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above scheme, by setting up the filter components and using the functions of the separation plate, demister block and other structures, the gas, liquid and water in the associated petroleum gas are effectively separated by the principles of density difference, temperature change and wire mesh coagulation, so that the gas discharged in the end is pure and the purity and quality of the resource are improved.

[0015] By setting up the filter components, water droplets dripping from the demister block are broken and dispersed as they pass through the separation plate and its separation holes, which helps the residual gas in the water droplets to escape, further improving the gas recovery rate and reducing gas waste.

[0016] By using the shaking component, the up-and-down shaking of the separation plate can effectively shake off the water droplets condensed in the separation plate and separation holes, preventing water droplets from accumulating on the separation plate and affecting the separation effect, thus ensuring that the separation plate can work continuously and efficiently.

[0017] By setting up the shaking component, larger water droplets can be broken up again during the shaking process, allowing the gas entrained in the water droplets to escape further, thereby significantly improving the gas-liquid separation effect and increasing the purity and separation efficiency of the gas.

Detailed Implementation

[0027] The present invention provides a petrochemical impurity filtration device in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] like Figures 1-5 As shown, an embodiment of the present invention provides a petrochemical impurity filtration device, including a tank 1, and a filter assembly 2 for filtering gaseous impurities in petroleum is installed on the inner wall of the tank 1.

[0029] Specifically, the filter assembly 2 includes a feed pipe 201 connected to one side of the tank body 1. An exhaust pipe 202 is connected to the top of the tank body 1. Several separation plates 203 are slidably arranged on the inner wall of the tank body 1. The separation plates 203 are conical, which allows the airflow moving upward from the tank body 1 to be evenly dispersed on its surface, avoiding the airflow from concentrating in a local area, thereby improving the efficiency and uniformity of gas-liquid separation. Due to the large bottom area of ​​the conical structure, the gas first contacts the bottom of the separation plate 203 during its ascent, and then gradually diffuses upward along the conical surface, allowing the gas to contact the separation plate 203 more fully. When the gas contacts the separation plate 203, water droplets in the gas will condense on the surface of the separation plate 203. The conical design makes it easier for the condensed water droplets to converge towards the bottom of the separation plate 203 under the action of gravity, and then slide down quickly along the conical surface, thereby effectively separating the water droplets from the gas.

[0030] Connecting plates 204 are fixedly installed on both sides of the separating plate 203. The connecting plates 204 slide against the inner wall of the tank body 1. Several separating holes 205 are opened on the separating plate 203. A baffle 206 is fixedly installed on one side of the inner wall of the tank body 1 near the feed pipe 201. A defoaming block 3 is fixedly installed at one end of the exhaust pipe 202 near the tank body 1. The defoaming block 3 includes a housing 301, which is fixedly installed on the inner wall of the exhaust pipe 202.

[0031] The shell 301 is made of corrosion-resistant, high-strength 304 stainless steel, which can adapt to complex working environments and effectively prevent corrosion damage caused by contact with associated petroleum gas and other impurities during long-term use, ensuring the overall structural stability and service life of the demister block 3. A support structure 302 is fixedly installed on the inner wall of the shell 301. The support structure 302 is supported by several wire meshes 303. The support structure 302 is set vertically, which makes it easier for water droplets in the gas to slide down the surface of the support structure 302 under the action of gravity. When the water vapor in the gas comes into contact with the vertical support structure 302, the water vapor will condense into water droplets on the surface of the structure. Since the direction of gravity is perpendicular to the support structure 302, the water droplets can quickly gather and flow down the support structure 302 under the action of gravity, thereby avoiding excessive accumulation of water droplets on the support structure 302 and affecting the demister effect.

[0032] The diameter of the filter holes in the wire mesh 303 is smaller than that of the separation holes 205. The separation holes 205 are mainly used for the preliminary separation of larger water droplets or liquid droplets in petroleum gas. The wire mesh 303 has a smaller filter hole diameter, which can perform finer filtration on the gas after the preliminary separation through the separation holes 205, intercept and condense smaller water droplets or water vapor in the gas, further improve the gas-liquid separation effect, make the final discharged gas purer, and reduce the impact of liquid droplets carried in the gas on subsequent equipment or processes. The side of the tank body 1 away from the feed pipe is connected to the liquid level controller pipe 207.

[0033] During the oil processing, associated petroleum gas needs to be filtered. Crude oil containing associated petroleum gas enters the tank 1 through the feed pipe 201. When the crude oil comes into contact with the baffle 206 at the outlet of the feed pipe 201, the flow direction is blocked by the baffle 206 and changes downward. Then it comes into contact with the cone-shaped separation plate 203 at the bottom of the tank 1. The separation plate 203 gradually narrows from the side closer to the tank 1 to the side of the exhaust pipe 202, causing the crude oil to flow along the outer wall of the separation plate 203 and the separation holes 205 on the plate to the bottom of the tank 1. During this process, the gas carried in the crude oil begins to move upward due to the density difference.

[0034] As the gas rises, it comes into contact with multiple cone-shaped separation plates 203 in sequence. Due to factors such as temperature changes, the water vapor carried in the gas condenses into larger water droplets and slides down the cone surface of the separation plate 203 to the bottom of the tank 1. When the gas reaches the demister block 3 at the top of the tank 1, the fine water droplets or water vapor carried in it enter the vertical support structure 302 of the demister block 3 and come into contact with the internal wire mesh 303. Under the action of the wire mesh 303, these tiny droplets further condense into larger water droplets, thereby achieving fine filtration of associated petroleum gas. The pure gas filtered by the demister block 3 enters the exhaust pipe 202 and is discharged from the tank 1.

[0035] Water droplets dripping from the defoaming block 3 are broken and dispersed by the separation plates 203 and their separation holes 205 as they pass through multiple separation plates 203. This process helps the residual gas in the water droplets to escape, while the oil collected at the bottom of the tank 1 is discharged under the control of the liquid level controller, thus completing the filtration operation of the associated gas in the oil and achieving effective separation of gas, liquid and water.

[0036] Furthermore, the inner wall of the tank body 1 is also equipped with a shaking component 4 to shake the water droplets condensed on the surface of the separation plate 203. The shaking component 4 includes a fixed block 401, and several fixed blocks 401 are fixedly arranged. Several fixed blocks 401 are fixedly arranged on the inner wall of the tank body 1. A sliding groove 402 is opened on the inner wall of the fixed block 401. A spring 403 is fixedly arranged on the inner wall of the sliding groove 402. One end of the spring 403 is fixed to the side near the sliding plate.

[0037] When the gas moves upward inside the tank 1, it comes into contact with the separation plate 203. At this time, the upward airflow generates a thrust that causes the separation plate 203 to move. Since the separation plate 203 is connected to the connecting plate 204, it causes the connecting plate 204 to slide along the inner wall of the tank 1. During the sliding process of the connecting plate 204, it exerts a squeezing effect on the spring 403 connected to it. After being subjected to force, the spring 403 stores elastic potential energy. When the gas thrust weakens, the spring 403 releases its potential energy and resets itself due to its own elasticity. This reset process pushes the connecting plate 204 in the opposite direction, thereby causing the separation plate 203 to shake up and down along the inner wall of the tank 1. Through this continuous up and down shaking, on the one hand, the water droplets condensed in the separation plate 203 and the separation hole 205 can be effectively shaken off, and on the other hand, larger water droplets can be dispersed again. After this operation, the gas entrained in the water droplets can be further released, thereby significantly improving the gas-liquid separation effect.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
