Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a device for preparing a catalyst for a high-temperature heavy oil viscosity reducer, which can prepare the catalyst for the high-temperature heavy oil viscosity reducer and filter harmful gases generated during the preparation process. Background Art

[0002] In the process of heavy oil extraction, viscosity reducers need to be added to reduce the viscosity of the oil so that it can be easily pumped out of the well. Adding a catalyst during the reaction between the viscosity reducer and the heavy oil can effectively improve the viscosity reduction effect.

[0003] The catalyst used in underground catalytic viscosity reduction production of heavy oil is transition metal sulfate, such as NiSO4, CoSO4, CuSO4 and VOSO4. NiSO4 is a weak acid or an acid with medium strength. Its molecular formula below 31 degrees is NiSO4·6H2O. After heating to 150 degrees, it turns into NiSO4·H2O. When it is heated to 300 degrees, it loses less water. However, if the temperature is raised further, the remaining water will be gradually lost. Generally, the acidity and catalytic activity are at their maximum at around 300 degrees.

[0004] The preparation of catalysts for high-temperature heavy oil viscosity reducers sometimes needs to be carried out at the mining site. During the preparation of the catalyst, the heating of metal sulfates may generate harmful gases such as sulfur dioxide and sulfur trioxide. If these harmful gases are directly discharged, they will not only harm the health of the workers, but also pollute the atmosphere. Since the preparation is carried out outdoors, it is not easy to centrally treat the harmful gases. Absorbents (such as limestone and activated carbon) must be used to adsorb the harmful gases. The adsorption capacity of the absorbent will gradually decrease with use. Traditional catalyst preparation equipment may have poor filtration efficiency because the absorbent cannot be replaced in time. Summary of the invention

[0005] The present invention provides a catalyst preparation device for a high-temperature heavy oil viscosity reducer. The weight of a solid absorbent placed on a slide plate is sensed by a spring in a filter component. When harmful gases are adsorbed to a certain extent, the solid absorbent gradually loses its adsorption capacity and its weight increases, pressing the slide plate and a support platform downward. When the spring is compressed to a certain extent, a spring push rod pushes a rectangular frame to drive the slide plate to slide out of the box, reminding a worker to replace the solid absorbent, so as to solve the problem of poor filtering efficiency of harmful gases generated in the catalyst preparation process in the background technology.

The filter assembly also comprises a shell, a chamber is provided on one side of the shell, a spring push rod is fixedly connected to the inner wall of the chamber, a rectangular frame is fixedly connected to the output end of the spring push rod, the support platform and the slide plate are located in the rectangular frame, the rectangular frame is slidably connected to the shell, an air inlet and a ventilation port are penetrated on the top of the shell, a slide groove 1 is provided on the top of the inner side of the shell, a slider is provided inside the slide groove 1, the slider is slidably connected to the slide groove 1, and a spring sheet is fixedly connected to one side of the slider.

[0008] Preferably, a turntable is fixedly connected to the bottom of the tray, and a support column is provided at the bottom of the tray, and the support column is rotatably connected to the turntable.

[0009] Preferably, a driven wheel is fixedly connected to the bottom of the support column, a plurality of electric telescopic rods are fixedly connected to the top of the driven wheel, a plurality of shaft seats corresponding to the electric telescopic rods are fixedly connected to the bottom of the tray, and the output end of the electric telescopic rod is rotatably connected to the shaft seat.

[0010] Preferably, a motor 1 is fixedly connected to the inner bottom of the base, a gear is fixedly connected to the output end of the motor 1, and the gear is meshed with the driven wheel.

[0011] Preferably, a cylinder is fixedly connected to the inner bottom of the base, and the cylinder is rotatably connected to the driven wheel.

[0012] Preferably, the ventilation pipe is made of flexible material.

[0013] Preferably, a solid absorbent is placed on the top of the slide.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention uses a support platform, a spring and a slide plate in combination. The catalyst is prepared by heating in the tank. The harmful gas generated in the preparation process passes through the pipeline through the ventilation pipe and then enters the filter assembly through the air inlet. When the filter assembly works normally, the spring will lift the support platform and the slide plate together. Part of the structure of the support platform and the slide plate will be located in the rectangular frame. Due to the limiting effect of the support platform, the spring push rod cannot push the rectangular frame out of the device at this time. As the solid absorbent placed on the slide plate continuously absorbs the harmful gas generated in the process of preparing the catalyst, its weight continues to increase, pressing the slide plate and the support platform downward, and the spring is gradually compressed until the support platform is completely squeezed out of the rectangular frame. At this time, the spring push rod can push the rectangular frame and the slide plate out of the shell, which is convenient for the staff to replace the solid absorbent and maintain the filtering capacity of the filter assembly.

[0016] 2. The present invention uses a rectangular frame and a slider in coordination. When the rectangular frame is pushed out of the filter assembly, the inner wall of the rectangular frame will fit with the spring sheet, driving the slider to slide in the slide groove 1 to block the air inlet. The slider cannot continue to move due to the limitation of the slide groove 1. Under the action of the thrust, the spring sheet is briefly squeezed and deformed, and the side wall of the rectangular frame will slide over the spring sheet and continue to move. When the solid absorbent is replaced and the rectangular frame is pushed back into the filter assembly, the outer wall of the rectangular frame will drive the spring sheet and the slider to move to open the air inlet. After the slider moves a certain distance, it will be limited by the slide groove 1. Under the action of the thrust, the rectangular frame will slide over the spring sheet and continue to move until it completely enters the filter assembly. The spring will lift the support table and fix the rectangular frame, thereby preventing the leakage of harmful gases when the solid absorbent is replaced, and further enhancing the function of protecting the environment.

[0017] 3. The present invention uses an electric telescopic rod in conjunction with a driven wheel. When the device is working outdoors and is arranged on a bottom surface with a certain slope, the multiple electric telescopic rods on the driven wheel are started to shorten the electric telescopic rod on one side and extend the electric telescopic rod on the other side, thereby driving the support column and the tray to rotate, causing the tank body to tilt. Then, the motor 1 is started, and its output end drives the gear to rotate, driving the driven wheel to rotate, and the driven wheel drives the box body to rotate. The electric telescopic rod works to adjust the appropriate angle to keep the tank body level, so that the inside of the tank body is evenly heated during the preparation of the catalyst, thereby improving product quality.

A plurality of stirring blades 209 and a plurality of fans 210 are fixedly connected to the rotating shaft 208. The stirring blades 209 rotate to make the raw materials in the tank body 202 heated more evenly. A ventilation pipe 207 is horizontally passed through one side of the pipeline 205, and the other end of the ventilation pipe 207 is connected with the internal space of the filter component 3. The harmful gas generated during the catalyst preparation process enters the filter component 3 through the pipeline 205 and the ventilation pipe 207. The filter component 3 includes a plurality of springs 301, and the tops of the plurality of springs 301 are fixedly connected with a support platform 302, and the top of the support platform 302 is provided with a slide groove 2 3021, a slide plate 303 is arranged on the top of the support platform 302, and the slide plate 303 is slidably connected to the support platform 302, the filter assembly 3 also includes a shell 311, a chamber is opened on one side of the shell 311, a spring push rod 310 is fixedly connected to the inner wall of the chamber, and a rectangular frame 304 is fixedly connected to the output end of the spring push rod 310, the support platform 302 and the slide plate 303 are located in the rectangular frame 304, and the rectangular frame 304 is slidably connected to the shell 311, an air inlet 306 and a ventilation port 305 are penetrated on the top of the shell 311, a slide groove 308 is opened on the inner top of the shell 311, a slider 307 is arranged inside the slide groove 308, and the slider 307 slides with the slide groove 308 The slider 307 is dynamically connected, and a spring sheet 309 is fixedly connected to one side of the slider 307.

The spring push rod 310 can push the rectangular frame 304 and the slider 303, and push both out of the filter component 3, so that the staff can replace the solid absorbent. In the process of the rectangular frame 304 being pushed out and pushed back into the filter component 3, the slider 307 will be driven by the spring sheet 309 to close and open the air inlet 306, so that the harmful gas will no longer enter the filter component 3 during the replacement of the solid absorbent, thereby reducing the leakage of harmful gases.

[0030] A turntable 104 is fixedly connected to the bottom of the tray 101, and a support column 103 is provided at the bottom of the tray 101. The support column 103 is rotatably connected to the turntable 104. When the turntable 104 and the support column 103 rotate, the tank body 202 will be driven to tilt. When the device is placed on a sloped ground, the tank body 202 in the device can be kept level.

[0031] A driven wheel 109 is fixedly connected to the bottom of the support column 103, and a plurality of electric telescopic rods 102 are fixedly connected to the top of the driven wheel 109. A plurality of shaft seats 105 corresponding to the electric telescopic rods 102 are fixedly connected to the bottom of the tray 101. The output end of the electric telescopic rod 102 is rotatably connected to the shaft seat 105. The extension and contraction of the electric telescopic rod 102 can drive the turntable 104 and the support column 103 to rotate, thereby facilitating the adjustment of the tilt angle of the tank body 202.

[0032] A motor 107 is fixedly connected to the inner bottom of the base 1, and a gear 108 is fixedly connected to the output end of the motor 107. The gear 108 is meshed with a driven wheel 109. When the motor 107 is started, its output end drives the gear 108 to rotate, and drives the driven wheel 109 to rotate, so that the entire box body 2 rotates. In conjunction with the electric telescopic rod 102, the appropriate angle can be better adjusted. When the device is placed on a sloping ground, the tank body 202 can be kept level.

[0033] A cylinder 106 is fixedly connected to the bottom of the inner side of the base 1 , and the cylinder 106 is rotatably connected to a driven wheel 109 . When the gear 108 rotates, the driven wheel 109 is driven to rotate around the cylinder 106 , so that the box body 2 rotates.

[0034] The ventilation pipe 207 is made of a flexible material, and when the tank body 202 is tilted in the box body 2, it still maintains the function of transmitting harmful gases.

[0035] A solid absorbent is placed on the top of the slide plate 303 to absorb harmful substances in the gas generated during the catalyst preparation process.

[0036] Embodiment 1: Figure 1-8As shown, in this embodiment, the catalyst preparation device for high-temperature heavy oil viscosity reducer is placed on the ground. If the ground has a slope, the multiple electric telescopic rods 102 on the driven wheel 109 are started to shorten the electric telescopic rod 102 on the higher side of the terrain and extend the electric telescopic rod 102 on the lower side of the terrain, driving the turntable 104 rotatably connected to the support column 103 to deflect, thereby driving the tray 101 to rotate, and rotating the tank body 202 to be parallel to the horizontal plane. If the tank body 202 is not parallel to the horizontal plane at this time, the motor 107 is started again, and its output end drives the gear 108 to rotate, drives the driven wheel 109 to rotate, and the driven wheel 109 drives the box body 2 to rotate, and cooperates with the electric telescopic rod 102 to adjust the appropriate angle until the tank body 202 is in a horizontal position, and the box cover 201 is opened, and the raw materials required for preparing the catalyst are injected into the tank body 202 from the inlet and outlet 204, and then the inlet and outlet 204 and the box cover 201 are closed. The preparation work is completed, and the preparation of the catalyst for viscosity reducer can be started.

[0037] The heating component 203 is started to heat the raw materials in the tank body 202 to reach the temperature required for catalysis. During the heating process, the motor 206 is started, and its output end drives the rotating shaft 208 to rotate, and the stirring blades 209 and the fan 210 on the rotating shaft 208 rotate together. The rotation of the stirring blades 209 can stir the raw materials in the tank body 202, so that the heating is more uniform and the preparation rate is improved. The rotation of the fan 210 allows the harmful gases generated in the preparation process to enter the pipeline 205, and then enter the ventilation pipe 207 through the pipeline 205, and then enter the filter component 3 from the ventilation pipe 207, and react with the solid absorbent in the filter component 3. Harmful components such as sulfur dioxide in the harmful gas are adsorbed, and the filtered gas is discharged into the box body 2 from the ventilation port 305. After the catalyst preparation is completed, the box cover 201 and the inlet and outlet 204 can be opened to put the catalyst into the work of reducing the viscosity of heavy oil.

[0038] During the process of filtering harmful gases by the filter assembly 3, the weight of the solid absorbent gradually increases due to continuous adsorption, and the pressure on the slide plate 303 and the support platform 302 gradually increases. The spring 301 at the bottom of the support platform 302 is gradually compressed, so that the height of the support platform 302 and the slide plate 303 gradually decreases. When the solid absorbent still has adsorption capacity, part of the support platform 302 will be located in the rectangular frame 304. At this time, due to the limitation of the support platform 302, the spring push rod 310 cannot push the rectangular frame 304. Figure 4 As shown, after the solid absorbent has been adsorbed for a long time, its weight gradually increases and its adsorption force gradually decreases, which will squeeze the support platform 302 to slide out of the rectangular frame 304. At this time, the adsorption capacity of the solid absorbent is insufficient, and the spring push rod 310 will push the rectangular frame 304 and the slide plate 303 out of the housing 311, as shown in FIG. Figure 5As shown, it is convenient for the staff to replace the solid absorbent. After the replacement is completed, the rectangular frame 304 and the slider 307 are pushed back into the shell 311, and the spring 301 will push the support platform 302 into the rectangular frame 304 to fix the rectangular frame 304, so that the filter component 3 can replace the solid absorbent in time to maintain the filtering capacity.

[0039] It should be noted that the weight difference of the solid absorbent replaced each time is small. When the spring push rod 310 pushes out the rectangular frame 304 and the slide plate 303, not the entire structure of the rectangular frame 304 and the slide plate 303 is pushed out of the filter assembly 3. The second slide groove 3021 opened on the top of the support platform 302 cooperates with the slide plate 303 to limit the pushing distance.

[0040] In the process of pushing the rectangular frame 304 and the slide 303 out of the filter assembly 3, the inner side of the side wall of the rectangular frame 304 will fit with the spring sheet 309, and push the spring sheet 309 and the slide 307 to move along the slide groove 1 308, blocking the air inlet 306, so that harmful gases stop entering the filter assembly 3. When the slide 307 moves to the edge of the slide groove 1 308, its position is restricted, and the thrust will squeeze the spring sheet 309, causing it to deform temporarily, allowing the side wall of the rectangular frame 304 to slide over the spring sheet. 309 and continue to move. When the rectangular frame 304 is pushed back into the filter assembly 3, the outer side of the side wall of the rectangular frame 304 will push the slider 307 to open the air inlet 306. When the slider 307 moves to the limit, the thrust will cause the rectangular frame 304 to slide over the spring sheet 309 and continue to move until it completes entering the filter assembly 3. At this time, the ventilation pipe 207 is connected to the filter assembly 3 again and continues to filter. Through the above steps, the leakage of harmful gases can be reduced while replacing the solid absorbent, thereby improving the reliability of the device.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
