Description

Technical Field

[0001] This utility model relates to the technical field of fixed-bed reactor equipment, specifically a series continuous flow hydrogenation fixed-bed reactor. Background Technology

[0002] A series continuous flow hydrogenation fixed bed is a device commonly used in the chemical industry for continuous hydrogenation reactions. The main feature of this device is that it fills one or more reactors in series with catalyst, and the reactants are brought into contact with hydrogen through continuous flow, thereby achieving a highly efficient hydrogenation reaction.

[0003] In this continuous hydrogenation reactor, the reactor is one of the main components. The reactor is filled with granular solid catalysts or solid reactants to form a bed of a certain height. Gas or liquid materials flow through the gaps between the particles through the stationary fixed bed, realizing a heterogeneous reaction process. However, the reactors in the existing series continuous flow hydrogenation fixed beds have short internal reaction paths, which leads to short reaction times, resulting in low reaction efficiency and inconvenience in use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the short reaction time in existing series continuous flow hydrogenation fixed bed reactors leads to low reaction efficiency and inconvenience in use due to the short internal reaction path, and to provide a series continuous flow hydrogenation fixed bed reactor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a series continuous flow hydrogenation fixed bed reactor, comprising: a reactor tank, a feed tank cover assembly fixedly disposed at one upper end of the reactor tank, a reaction chamber assembly fixedly disposed inside the reactor tank, and a discharge tank seat fixedly disposed at one lower end of the reactor tank.

[0006] As a further embodiment of this utility model: the feed tank cover assembly includes a feed tank cover body, a feed pipe is fixedly inserted through the middle of the feed tank cover body, a discharge ring seat is fixedly provided at one end of the feed pipe, a buffer discharge head is fixedly connected to one end of the discharge ring seat, and a discharge through hole is opened on the side of the buffer discharge head.

[0007] As a further embodiment of this utility model: a can cover connecting flange ring is fixedly provided on one side of the feed tank cover body, and a can cover mounting through hole is opened inside the can cover connecting flange ring. Multiple sets of buffer discharge head, discharge through hole and can cover mounting through hole are provided.

[0008] As a further embodiment of this utility model: the reaction chamber assembly includes a sealed chamber cylinder, a fan-shaped connecting plate is fixedly installed at one upper end of the inner side of the sealed chamber cylinder, a hollow inner tube is fixedly installed at one end of the fan-shaped connecting plate, and a spiral plate is fixedly installed at one outer end of the hollow inner tube.

[0009] As a further embodiment of this utility model: an upper ceramic ring is fixedly installed at the upper part of the sealed chamber near the fan-shaped connecting plate, a lower ceramic ring is fixedly installed at one end of the lower part of the sealed chamber, a supporting mesh plate is installed at one end of the lower ceramic ring, and the outer side of the lower ceramic ring is fixedly connected to the sealed chamber.

[0010] As a further embodiment of this utility model: the number of the fan-shaped connecting plates is arranged in multiple sets, the hollow inner tube protrudes above the fan-shaped connecting plates, and the spiral plate is arranged between the upper ceramic ring and the lower ceramic ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the raw material liquid enters the discharge ring seat through the feed pipe and flows out evenly through the discharge holes of multiple sets of buffer discharge heads. At this time, the raw material liquid falls onto the reaction chamber assembly below and flows into the interior through the gaps between multiple sets of fan-shaped connecting plates. After passing through the upper ceramic ring, it reacts with the internal granular solid catalyst or solid reactant, and flows along the spiral plate from top to bottom, finally passing through the lower ceramic ring and the supporting mesh plate and flowing out through the discharge pipe at the bottom of the discharge tank seat to complete the reaction. This structure can effectively improve the reaction effect between the raw material liquid and the granular solid catalyst or solid reactant, and the extended path allows the raw material liquid and the granular solid catalyst or solid reactant to react more evenly, making it more convenient to use.

[0020] Reference Figure 1 and Figure 2 In this embodiment of the present invention, a series continuous flow hydrogenation fixed bed reactor includes: a reactor tank 1, a feed tank cover assembly 2 fixedly disposed at one upper end of the reactor tank 1, a reaction chamber assembly 3 fixedly disposed inside the reactor tank 1, and a discharge tank seat 4 fixedly disposed at one lower end of the reactor tank 1.

[0021] Reference Figure 3The feed tank cover assembly 2 includes a feed tank cover body 20. A feed pipe 21 is fixedly inserted through the middle of the feed tank cover body 20. A discharge ring seat 22 is fixedly installed at one end of the feed pipe 21. A buffer discharge head 23 is fixedly connected to one end of the discharge ring seat 22. A discharge through hole 24 is opened on the side of the buffer discharge head 23. A tank cover connecting flange ring 25 is fixedly installed at one end of the side of the feed tank cover body 20. A tank cover mounting through hole 26 is opened inside the tank cover connecting flange ring 25. Multiple sets of buffer discharge head 23, discharge through hole 24 and tank cover mounting through hole 26 are provided.

[0022] The above scheme is adopted: by connecting the feed pipe to the feed pipe 21, the raw material liquid enters the discharge ring seat 22 through the feed pipe 21 and flows out evenly through the discharge through holes 24 of multiple sets of buffer discharge heads 23. This structure can effectively buffer the feeding of the raw material liquid.

[0023] Reference Figure 4 The reaction chamber assembly 3 includes a sealed chamber cylinder 30. A sector-shaped connecting plate 31 is fixedly installed at one end of the upper inner side of the sealed chamber cylinder 30. A hollow inner tube 32 is fixedly installed at one end of the sector-shaped connecting plate 31. A spiral plate 33 is fixedly installed at one end of the outer side of the hollow inner tube 32. An upper ceramic ring 34 is fixedly installed at the upper inner side of the sealed chamber cylinder 30 near the sector-shaped connecting plate 31. A lower ceramic ring 35 is fixedly installed at one end of the lower inner side of the sealed chamber cylinder 30. A supporting mesh plate 36 is installed at one end below the lower ceramic ring 35.

The spiral plate 33 is located between the upper ceramic ring 34 and the lower ceramic ring 35. The outer side of the lower ceramic ring 35 is fixedly connected to the sealed chamber cylinder 30.

[0024] The above scheme is adopted: the raw material liquid falls into the reaction chamber assembly 3 below, flows into the interior through the gaps between multiple sets of fan-shaped connecting plates 31, passes through the upper ceramic ring 34 and reacts with the internal granular solid catalyst or solid reactant, and flows down along the spiral plate 33 from top to bottom, finally passing through the lower ceramic ring 35 and the supporting mesh plate 36 and flowing out from the discharge pipe below the discharge tank seat 4 to complete the reaction. This structure can effectively improve the reaction effect between the raw material liquid and the granular solid catalyst or solid reactant, and the extended path allows the raw material liquid and the granular solid catalyst or solid reactant to react more evenly and make the use more convenient. In addition, the hollow inner tube 32 is located above the fan-shaped connecting plate 31 and protrudes a section, which can effectively prevent the raw material liquid from flowing out from the hollow inner tube 32.

[0025] The working principle of this utility model is as follows: First, granular solid catalysts or solid reactants are filled onto the outside of the spiral plate 33 inside the sealed chamber cylinder 30. Then, the entire reaction chamber assembly 3 is installed inside the reactor tank 1. Next, the feed tank cover assembly 2 and the discharge tank seat 4 are fixedly installed on the upper and lower sides of the reactor tank 1 using bolts. At this time, a feed pipe is connected to the feed pipe 21, and the raw material liquid enters the discharge ring seat 22 through the feed pipe 21 and flows out evenly through the discharge through-holes 24 of multiple sets of buffer discharge heads 23. The raw material liquid then falls into the lower... On the square reaction chamber assembly 3, the liquid flows into the interior through the gaps between multiple sets of fan-shaped connecting plates 31, passes through the upper ceramic ring 34, reacts with the internal granular solid catalyst or solid reactant, and flows down the spiral plate 33 from top to bottom, finally passing through the lower ceramic ring 35 and the supporting mesh plate 36, and flows out from the discharge port below the discharge tank seat 4 to complete the reaction. This structure can effectively improve the reaction effect between the raw material liquid and the granular solid catalyst or solid reactant, and the extended path allows the raw material liquid and the granular solid catalyst or solid reactant to react more evenly, making it more convenient to use.
