Description

Technical Field

[0001] This utility model relates to the technical field of sodium methoxide production equipment, and more specifically, to a high-efficiency sodium methoxide reaction tower with a layered feeding structure. Background Technology

[0002] Sodium methoxide production equipment is a chemical plant used to produce sodium methoxide. It mainly consists of a reaction tower, feeding system, heating system, gas distribution system, liquid distribution system, and temperature control system. Its core is the reaction tower, which contains multiple reaction sections (such as sieve plates and corrugated packing). Through layered feeding, heating, and gas-liquid distribution, caustic soda and methanol vapor are brought into full contact and react to produce sodium methoxide. This equipment improves the efficiency of sodium methoxide production and reduces production costs by optimizing raw material distribution and reaction conditions.

[0003] A search revealed an existing patent (publication number: CN206334646U) that discloses a sodium methoxide reaction tower, comprising a tower body, several first reaction sections and several second reaction sections disposed inside the tower body. The top of the tower body has a gas outlet and a liquid inlet; the bottom of the tower body has a liquid outlet and a gas inlet, both of which are equipped with first heaters; a gas distributor is disposed at the bottom of the tower body, with its inlet connected to the gas inlet; each first reaction section includes a second heater and a sieve plate fixed to the inner wall of the tower body, the sieve plate being fixedly mounted on the second heater; each second reaction section includes corrugated packing, a third heater, a grid support plate, and a liquid distributor, the grid support plate being fixedly connected to the inner wall of the tower body, the third heater being fixedly mounted on the grid support plate, the corrugated packing being fixedly mounted on the third heater, and the liquid distributor being fixedly mounted on the corrugated packing. This reaction tower ensures thorough mixing of the reactants and complete reaction at high temperature, resulting in high efficiency in producing sodium methoxide and reducing the cost of sodium methoxide production.

[0004] The above-mentioned device only feeds from one inlet, and the raw material will concentrate on impacting a certain area inside the tower, resulting in an excessively high raw material concentration in that area, while the raw material concentration in other areas is low, forming an uneven distribution. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a high-efficiency sodium methoxide reaction tower with a layered feeding structure to solve the problem of uneven concentration distribution caused by single-inlet feeding.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency sodium methoxide reaction tower with a layered feeding structure, comprising: a tower body; a layered feeding assembly mounted on the tower body, the layered feeding assembly being used for layered injection and diversion of liquid; a reaction heating assembly mounted inside the tower body, the reaction heating assembly being used for heating and mixing the liquid; a gas feedstock injection assembly mounted inside the layered feeding assembly, the gas feedstock injection assembly being used for mixing gas feedstock; a bottom liquid outlet assembly mounted at the bottom of the tower body, the bottom liquid outlet assembly being used for liquid outlet and heating of the internal liquid; and a gas balancing assembly mounted at the top of the tower body, the gas balancing assembly being used for balancing the gas pressure inside the tower body.

[0007] Preferably, the stratified feeding assembly includes: a liquid inlet pipe fixedly installed on the tower body, a hopper fixedly installed at one end of the liquid inlet pipe, a rotating shaft movably installed on the tower body, and a liquid separator fixedly installed on the outer surface of the rotating shaft.

[0008] Preferably, the stratified feeding assembly further includes: a separating plate fixedly installed inside the separating hopper, the separating hopper having a liquid outlet, and two sets of liquid outlets symmetrically arranged on the separating hopper.

[0009] Preferably, the layered feeding assembly is provided in three sets, and the three sets of layered feeding assemblies are equidistantly arranged inside the tower body.

[0010] Preferably, the reaction heating assembly includes: corrugated packing fixedly installed inside the tower body, a heater fixedly installed at the bottom of the corrugated packing, a grid support plate fixedly installed at the bottom of the heater, and a liquid distributor fixedly installed at the top of the corrugated packing.

[0012] Preferably, the gas feedstock injection assembly includes: an air inlet pipe fixedly installed on one side of the tower body, and a gas distributor fixedly installed at one end of the air inlet pipe.

[0013] Preferably, the bottom liquid outlet assembly includes: a bottom cover plate fixedly installed at the bottom of the tower body, a heater II fixedly installed inside the bottom cover plate, and a liquid outlet pipe fixedly installed at the bottom of the bottom cover plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a mixture of caustic soda and methanol, which enters the hopper through an inlet pipe. Driven by a rotating shaft, a distributor plate in the hopper evenly distributes the liquid, injecting it into the tower body in layers through two symmetrically arranged outlets. Gaseous feedstock enters the gas distributor through an inlet pipe, where it is evenly dispersed and thoroughly mixed with the liquid within the tower. Inside the tower, the liquid flows through a three-component layered feed assembly and reacts with the gaseous feedstock under the action of the reaction heating assembly. The corrugated packing, heater one, grid support plate, and liquid distributor work together to evenly distribute and heat the liquid, promoting the reaction. Heater two at the bottom of the tower heats the liquid at the bottom, causing methanol to vaporize and rise, mixing with methanol vapor flowing from the gas distributor to form a supersaturated state, promoting the formation of sodium methoxide. The generated sodium methoxide solution flows downwards and is finally discharged from the outlet pipe of the bottom cover plate. A gas balance valve at the top of the tower regulates the gas pressure, ensuring stable pressure inside the tower and guaranteeing a smooth reaction process, thereby achieving uniform mixing of the reactants inside.

[0029] Example 2

[0030] Based on Example 1, a preferred embodiment of the high-efficiency sodium methoxide reaction tower with a layered feeding structure provided by this utility model is as follows: Figures 1 to 4 As shown: The reaction heating assembly 3 includes: a corrugated packing 301 fixedly installed inside the tower body 1, a heater 302 fixedly installed at the bottom of the corrugated packing 301, a grid support plate 303 fixedly installed at the bottom of the heater 302, and a liquid distributor 304 fixedly installed at the top of the corrugated packing 301.

[0031] In this embodiment, three sets of corrugated packing 301, heater 302, grid support plate 303, and liquid distributor 304 are provided, and the three sets of corrugated packing 301, heater 302, grid support plate 303, and liquid distributor 304 are equidistantly arranged inside the tower body 1.

[0035] In Examples 1 and 2, the operation of the high-efficiency sodium methoxide reaction tower with a stratified feeding structure is as follows: First, a mixed solution of caustic soda and methanol enters the hopper 202 through the inlet pipe 201.

The generated sodium methoxide solution flows downwards and is eventually discharged from the outlet pipe 503 of the bottom cover plate 501. The gas balance valve pipe 602 at the top of the tower regulates the gas pressure to ensure stable pressure inside the tower and to ensure the smooth progress of the entire reaction process, thereby achieving the effect of uniform mixing of the internal reaction raw materials.
