Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid distributors, in particular to a trough-plate type gas-liquid distributor for catalytic reaction distillation. Background Art

[0002] The slotted plate type gas-liquid distributor is a key device used to effectively separate and distribute gas and liquid phases to the catalyst bed in the reactor. It is usually composed of a series of horizontally placed slotted plates, each of which has some small holes or other forms of channels so that gas and liquid can pass through. This design helps to achieve effective contact between gas and liquid, thereby promoting the catalytic reaction. During the catalytic reaction, the gas and liquid mixture enters the slotted plate type gas-liquid distributor. Through the holes or channels on the slotted plate, the gas is dispersed into small bubbles, and the liquid is also evenly distributed on the slotted plate. In this way, the gas and liquid can fully contact on the slotted plate, thereby improving the efficiency of the reaction. At the same time, due to the design of the slotted plate type gas-liquid distributor, the flow of gas and liquid in the distributor can be controlled, so that it enters the catalyst bed more evenly, avoiding problems such as runaway reaction or local overheating of the catalyst bed caused by uneven flow. In general, the slotted plate type gas-liquid distributor plays a vital role in catalytic reaction distillation. It can effectively separate the gas and liquid phases and evenly distribute them to the catalyst bed, thereby improving the efficiency and selectivity of the reaction.

[0003] For example, the application number CN217005103U discloses a mixed liquid distribution trough disc distributor, which consists of a plurality of liquid troughs and a liquid baffle plate at the bottom, wherein the liquid trough consists of two vertically arranged drainage plates and a bottom plate connecting the two drainage plates, and each drainage plate is provided with a waist-shaped hole at the upper portion for the rising gas to flow out; symmetrical trough bottom liquid holes are respectively provided at the lower portions of the two vertically arranged drainage plates for the liquid to flow out vertically downward, and the liquid holes are equidistantly distributed along the axial direction of the drainage plates and perpendicular to the axial direction of the drainage plates to achieve uniform point distribution of the liquid, and two rows of trough side liquid holes are also provided on the bottom plate for the liquid to flow out to both sides, and the aperture diameter of the trough side liquid holes is the same as that of the trough bottom liquid holes, and left and right liquid baffle plates are respectively provided at the lower outer portions of the two vertically arranged drainage plates for shielding the liquid flowing out of the liquid trough side liquid holes and allowing the liquid to flow down along the liquid baffle plates. The utility model has the advantages of simple structure, convenient production, installation and disassembly, low manufacturing cost and greatly improved distillation performance of fillers.

[0004] However, this mixing liquid distribution trough disc distributor does not take into account that the trough disc type gas-liquid distributor is usually composed of many tiny holes or channels, and these pores are easily blocked by sediments or accumulations produced in the catalytic reaction, affecting the separation efficiency and reducing the working efficiency of the device.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a trough-plate type gas-liquid distributor for catalytic reaction distillation is proposed. Utility Model Content

[0006] The utility model aims to provide a trough-disc type gas-liquid distributor for catalytic reaction distillation, so as to solve the problem in the above background technology that the channel is easily blocked by the sediment or accumulation produced in the catalytic reaction, thus affecting the separation effect and reducing the working efficiency of the device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a trough-disc type gas-liquid distributor for catalytic reaction distillation, comprising a gas lifting trough, a plurality of liquid separation holes are arranged through the gas lifting trough, a mounting plate is fixedly arranged on the gas lifting trough, a telescopic rod is arranged at the bottom of the mounting plate, a mounting shell is movably arranged on the outer surface of the gas lifting trough, a plurality of dampers are fixedly arranged on the inner wall of the mounting shell, a spring is arranged on the outer surface of the damper, a push plate is fixedly arranged at one end of the damper, a cleaning brush is arranged on one side of the push plate, and the cleaning brush corresponds to the liquid separation hole.

[0008] Furthermore, a bottom plate is provided at the bottom of the air lifting groove, and an air lifting cap is provided above the air lifting groove.

[0009] Furthermore, a support plate is provided in the air lifting groove, and the top of the support plate is connected to the air lifting cap.

[0010] Furthermore, a plurality of liquid guide plates are arranged on the inner wall of the gas lifting groove, and the liquid guide plates are connected with the liquid separation holes.

[0011] Furthermore, a protective shell is fixedly provided on the bottom of the mounting plate, and the protective shell forms a protective wrapping for the telescopic rod.

[0012] Furthermore, a plurality of first sliding blocks are fixedly disposed on the outer surface of the air lifting groove, and the first sliding blocks are located at the top of the liquid separation hole.

[0013] Furthermore, a second slider is fixedly arranged on the push plate, and the second slider is movably located on one side of the first slider and is symmetrically arranged.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model provides a cleaning brush. When the liquid separation hole of the trough-disc type gas-liquid distributor of the catalytic reaction distillation is blocked, the mounting shell is set in an L shape and movably located on the outer surface of the gas lifting slot. The damper is set corresponding to the multiple liquid guide plates. The push plate serves to provide a role in installing the cleaning brush. The telescopic operation of the telescopic rod can drive the mounting shell and the cleaning brush to move up and down at the same time. When the cleaning brush moves to correspond to the liquid guide plate, the elastic expansion and contraction effect of the damper and the spring will push the cleaning brush to pass through the liquid separation hole. The cleaning brush can form a breaking and penetrating effect on the blockage in the liquid separation hole, which effectively solves the problem that the channel is easily blocked by sediments or accumulations generated in the catalytic reaction, which affects the separation effect and reduces the working efficiency of the device.

When the liquid separation hole of the trough-disc type gas-liquid distributor of the catalytic reaction distillation is cleaned, a protective shell is provided to protect the telescopic rod. When the telescopic rod drives the mounting shell to move, the first slider and the second slider are provided in a triangular shape. When moving, the second slider will follow the angle of the first slider to drive the push plate and the cleaning brush to extend and retract, thereby positioning the angle of the cleaning brush and the liquid separation hole and forming a moving space for the cleaning brush to avoid the problem of contact and extrusion with the side wall of the gas lifting groove to reduce the service life.

The telescopic operation of the telescopic rod 211 can drive the mounting shell 3 and the cleaning brush 314 to move up and down at the same time. When the cleaning brush 314 moves to correspond to the liquid guide plate 113, the elastic expansion and contraction effect of the damper 31 and the spring 311 will push the cleaning brush 314 to pass through the liquid separation hole 114. The cleaning brush 314 can break and penetrate the blockage in the liquid separation hole 114, effectively solving the problem that the channel is easily blocked by sediments or accumulations generated in the catalytic reaction, which affects the separation effect and reduces the working efficiency of the device.

The air lifting trough 1 and the bottom plate 11 are existing structures and therefore no further details are given. The support plate 111 serves to provide stable support for the installation of the air lifting cap 112.

[0027] Embodiment 2

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a trough-disc type gas-liquid distributor for catalytic reaction distillation proposed by the utility model is another embodiment of the utility model compared to Example 1. A protective shell 21 is fixedly arranged at the bottom of the mounting plate 2, and the protective shell 21 forms a protective package for the telescopic rod 211. A plurality of first sliders 12 are fixedly arranged on the outer surface of the gas lifting trough 1, and the first slider 12 is located at the top of the liquid separation hole 114. A second slider 313 is fixedly arranged on the push plate 312, and the second slider 313 is movably arranged on one side of the first slider 12 and is symmetrically arranged.

[0029] Furthermore, when the liquid separation hole 114 of the trough-disc type gas-liquid distributor of the catalytic reaction distillation is cleaned, the protective shell 21 is provided to protect the telescopic rod 211. When the telescopic rod 211 drives the mounting shell 3 to move, the first slider 12 and the second slider 313 are arranged in a triangular shape. When moving, the second slider 313 will follow the angle of the first slider 12 to drive the push plate 312 and the cleaning brush 314 to extend and retract, thereby positioning the angle of the cleaning brush 314 and the liquid separation hole 114, and forming a moving space for the cleaning brush 314, thereby avoiding the problem of contact and extrusion with the side wall of the gas lifting tank 1 to reduce the service life.

[0030] Working principle: When using this kind of trough-disc type gas-liquid distributor for catalytic reaction distillation, first, when the liquid separation hole 114 of the trough-disc type gas-liquid distributor for catalytic reaction distillation is blocked, the mounting shell 3 is set to be L-shaped and movably located on the outer surface of the gas lifting slot 1, and the damper 31 is set corresponding to the multiple liquid guide plates 113. The push plate 312 serves to provide a cleaning brush 314 for installation. The telescopic operation of the telescopic rod 211 can drive the mounting shell 3 and the cleaning brush 314 to move up and down at the same time. When the cleaning brush 314 moves to correspond to the liquid guide plate 113, the elastic expansion and contraction effect of the damper 31 and the spring 311 will push the cleaning brush 314 to pass through the liquid separation hole 114. The cleaning brush 314 can break and penetrate the blockage in the liquid separation hole 114, effectively solving the problem that the channel is easily blocked by sediments or accumulations generated in the catalytic reaction, which affects the separation effect and reduces the working efficiency of the device.

[0031] Finally, when the liquid separation hole 114 of the trough-disc type gas-liquid distributor of the catalytic reaction distillation is cleaned, the protective shell 21 is provided to protect the telescopic rod 211. When the telescopic rod 211 drives the mounting shell 3 to move, the first slider 12 and the second slider 313 are arranged in a triangular shape. When moving, the second slider 313 will follow the angle of the first slider 12 to drive the push plate 312 and the cleaning brush 314 to extend and retract, thereby positioning the angle of the cleaning brush 314 and the liquid separation hole 114, and forming a moving space for the cleaning brush 314 to avoid the problem of contact and extrusion with the side wall of the gas lifting tank 1 to reduce the service life.
