Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, and in particular relates to an adjustable temperature coal-to-ethanol distillation tower. Background Technology

[0002] Distillation towers are chemical equipment made of rare metals such as titanium and their alloys. They have the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance and light weight. Therefore, they are widely used in chemical, petrochemical, metallurgical, light industry, textile, alkali production, pharmaceutical, pesticide, electroplating, electronics and other fields. The working principle of distillation towers is to use the principle of fractionation to separate the components in a mixture through processes such as evaporation and condensation.

[0003] A search revealed CN222871356U, filed on April 15, 2025, which discloses a catalytic distillation column belonging to the field of distillation column technology. The column includes: a lower column body and an upper column body on a catalytic chamber; a catalytic assembly for placing a catalyst is inserted into the catalytic chamber. The lower and upper columns are connected through the catalytic chamber, and the three components together form a reaction chamber internally; the fluid material in the reaction chamber can pass through the catalyst assembly to achieve a catalytic reaction. The catalytic assembly includes: a catalyst mesh box and a packing mesh for dispersing the fluid material are clamped onto an insert plate, the packing mesh and catalyst mesh box being stacked; a sealing gasbag is embedded in the insert plate for sealing between itself and the catalytic chamber.

[0004] However, it still has the following drawbacks in practical use:

[0005] Existing adjustable temperature coal-to-ethanol distillation towers directly exhaust the high-temperature gas inside the tower for cooling after use, resulting in a large amount of heat loss and increased equipment energy consumption.

[0006] 2. Existing adjustable temperature coal-to-ethanol distillation columns involve directly sliding the catalytic module into the catalytic chamber during use. However, this method lacks a limiting effect on the catalytic chamber, making it prone to detachment during operation and resulting in poor stability. Therefore, we provide an adjustable temperature coal-to-ethanol distillation column to address the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a temperature-adjustable coal-to-ethanol distillation tower. By setting up a circulation component, a fan extracts the residual high-temperature steam in the tower body and circulates it into the heater, thereby reducing heat loss and energy consumption. Additionally, a limiting component is used to introduce gas into the gas cylinder, and under the elastic action of the spring, the T-shaped column can be quickly inserted into or removed from the limiting hole, thereby achieving or releasing the limiting effect on the sliding frame. This facilitates the quick assembly and disassembly of the sliding frame by the workers and also limits the sliding frame to prevent it from falling off.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a temperature-adjustable coal-to-ethanol distillation tower, including a tower body and a discharge pipe located at the center of its top. A catalytic chamber is provided in the middle of the tower body. Sliding grooves are provided at the top and bottom of the catalytic chamber. A sliding frame is slidably installed in the sliding grooves. An installation groove is provided at the front of both ends of the sliding frame. A circulation component is provided at the rear of the tower body. A limit component is provided inside the installation groove.

[0010] The circulation assembly includes a fan installed at the rear of the tower body, and a first connecting pipe installed at the air inlet of the fan via a pipe joint. The other end of the first connecting pipe is connected to the discharge pipe via a pipe joint.

[0011] The limiting assembly includes an air cylinder installed in a mounting slot, and pistons slidably mounted above and below the inside of the air cylinder.

[0012] The present invention is further configured such that a high-temperature steam pipe is provided on the lower side of one side of the outer wall of the tower body, a heater is provided on one side of the tower body, and a feed pipe is provided on the outer wall side of the heater.

[0013] The present invention is further configured such that a discharge pipe is provided on the other side of the outer wall of the heater, the other end of the discharge pipe is provided on the outer wall of the tower body, and limit holes are provided on both sides of the top and bottom of the chute.

[0014] The present invention is further provided with sealing grooves at the center of the top and bottom of the sliding frame, and an external air pipe at the front of the sliding frame.

[0015] The present invention is further configured such that the external air tube is connected to two sealing airbags through a pipe connector, and the sealing airbags are installed in the sealing groove.

[0016] The present invention is further configured such that the air outlet end of the blower is connected to the second connecting pipe through a pipe joint, and the other end of the second connecting pipe is connected to the feed pipe and the raw material pipe through a three-joint.

[0017] The present invention is further configured such that an air inlet pipe is provided at the center of the front end face of the air cylinder, and the other end of the air inlet pipe is connected to an external air pipe through a branch pipe.

[0018] The present invention is further configured such that a T-shaped post is installed in the middle of the outer wall of the piston, and a spring is sleeved on the outer wall of the T-shaped post, and the spring is located between the piston and the inner wall of the cylinder.

[0019] This utility model has the following beneficial effects:

[0020] This invention reduces heat loss and energy consumption by setting up a circulation component, in which a fan extracts the residual high-temperature steam in the tower and circulates it into the heater. This solves the problem of existing adjustable temperature coal-to-ethanol distillation towers directly discharging the high-temperature gas in the tower after use for cooling, resulting in a large amount of heat loss and increased equipment energy consumption.

[0021] This invention, by setting a limiting component, allows gas to be introduced into the gas cylinder, and under the elastic action of the spring, the T-shaped column can be quickly inserted into or removed from the limiting hole, thereby achieving or releasing the limiting effect on the sliding frame. This facilitates quick assembly and disassembly of the sliding frame by the operator and also limits the sliding frame to prevent it from falling off. This solves the problem of existing adjustable temperature coal-to-ethanol distillation towers where the catalyst component is directly slid into the catalyst chamber during use, but this method lacks a limiting effect on the catalyst chamber, making it prone to falling off during use and resulting in poor stability.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 5 This utility model is a temperature-adjustable coal-to-ethanol distillation tower, including a tower body 100 and a discharge pipe 102 located at the center of its top. A catalyst chamber 104 is provided in the middle of the tower body 100. Sliding grooves 104a are provided at the top and bottom of the interior of the catalyst chamber 104. A sliding frame 105 is slidably installed in the sliding grooves 104a. An installation groove 105b is provided at the front of both ends of the sliding frame 105. A circulation component 200 is provided at the rear of the tower body 100. The circulation component 200 includes a fan 201 installed at the rear of the tower body 100 and a first connecting pipe 202 installed at the air inlet of the fan 201 through a pipe joint. The other end of the first connecting pipe 202 is connected to the discharge pipe 102 through a pipe joint.

[0034] Specifically, a high-temperature steam pipe 101 is provided on the lower side of one side of the outer wall of the tower body 100, a heater 103 is provided on one side of the tower body 100, and a feed pipe 103a is provided on one side of the outer wall of the heater 103; a discharge pipe 103b is provided on the other side of the outer wall of the heater 103, and the other end of the discharge pipe 103b is provided on the outer wall of the tower body 100; limit holes 104b are provided on both sides of the top and bottom of the sliding groove 104a; a sealing groove 105a is provided at the center of the top and bottom of the sliding frame 105; an external air pipe 106 is provided in front of the sliding frame 105; the external air pipe 106 is connected to two sealing air bags 106a through a pipe joint, and the sealing air bags 106a are installed in the sealing groove 105a; the air outlet of the blower 201 is connected to the second connecting pipe 203 through a pipe joint, and the other end of the second connecting pipe 203 is connected to the feed pipe 103a and the raw material pipe 204 through a three-joint.

[0035] Furthermore, the sliding frame 105 is slidably inserted into the slide groove 104a, which facilitates quick assembly and disassembly of the sliding frame 105. High-temperature steam can be introduced into the tower body 100 through the high-temperature steam pipe 101 to adjust the temperature of the raw material liquid. The heater 103 can be used to heat the raw material liquid. The limiting hole 104b is correspondingly set with the T-shaped column 303. The sealing airbag 106a can seal the connection between the sliding frame 105 and the catalyst chamber 104.

[0036] The operation process of this embodiment is as follows: the raw material liquid is introduced into the tower body 100 through the raw material pipe 204 and needs to be heated by the heater 103 first. In order to facilitate the control and adjustment of the temperature of the raw material liquid, high-temperature steam can be introduced through the high-temperature steam pipe 101 during the distillation of the raw material liquid. After the raw material liquid is distilled, the ethanol solution is discharged. At this time, the blower 201 is started. The blower 201 runs and extracts the remaining high-temperature steam in the tower body 100 through the discharge pipe 102, and then sends it back into the heater 103 through the first connecting pipe 202 and the second connecting pipe 203, thereby reducing heat loss and reducing energy consumption.

[0037] Example 2

[0038] Please see Figure 4 and Figure 6 Based on Embodiment 1, but different from the first embodiment, a limiting component 300 is provided. The limiting component 300 includes a gas cylinder 301 installed in the mounting groove 105b, and a piston 302 slidably installed above and below the gas cylinder 301. This solves the problem that in the existing adjustable temperature coal-to-ethanol distillation tower, the catalyst component is directly slidably inserted into the catalyst chamber during use. However, this method lacks a limiting effect on the catalyst chamber, which is prone to falling off during use and has poor stability.

[0039] Specifically, an air inlet pipe 301a is provided at the center of the front end face of the air cylinder 301, and the other end of the air inlet pipe 301a is connected to the external air pipe 106 through a branch pipe; a T-shaped column 303 is installed in the middle of the outer wall of the piston 302, and a spring 303a is sleeved on the outer wall of the T-shaped column 303, and the spring 303a is located between the piston 302 and the inner wall of the air cylinder 301.

[0040] Furthermore, the piston 302 is slidably installed in the air cylinder 301, and the size of the T-shaped post 303 is smaller than that of the limiting hole 104b. Under the elastic action of the spring 303a, the positions of the T-shaped post 303 and the piston 302 can be adjusted.

[0041] The operation process of this embodiment is as follows: When the raw material liquid is introduced into the tower body 100 for distillation, the catalyst in the sliding frame 105 can be used to accelerate the ethanol distillation efficiency. When it is necessary to disassemble or replace the catalyst, firstly, the gas in the gas cylinder 301 is vented through the valve. Then, under the elastic action of the spring 303a, the upper and lower sets of pistons 302 are pushed to the middle of the gas cylinder 301, so that the T-shaped column 303 moves out of the limiting hole 104b, releasing the limiting effect on the sliding frame 105. Then, the sliding frame 105 is slidably disassembled, and the catalyst inside is replaced. During installation, the sliding frame 105 is slidably disassembled. The frame 105 can be slid into the slide groove 104a. Then, gas is introduced into the air cylinder 301 and the sealing air bag 106a through the external air pipe 106. The air pressure in the air cylinder 301 increases, pushing the upper and lower parts to move outward and compressing the spring 303a. At this time, the T-shaped column 303 will be inserted into the corresponding limiting hole 104b, which will limit the sliding frame 105 and complete the installation of the sliding frame 105. This makes it easier for workers to quickly assemble and disassemble the sliding frame 105 and also limits the sliding frame 105 to prevent it from falling off.
