[0001] This utility model relates to the technical field of high mast light protection devices, and in particular to a methylcyclohexane feed gas preheating device. Background Technology

[0002] Methylcyclohexane is an organic compound, a colorless and transparent liquid, insoluble in water but soluble in ethanol, ether, acetone, benzene, petroleum ether, carbon tetrachloride, etc. It is mainly used as a solvent, a standard substance for chromatographic analysis, and a standard for calibrating thermometers. It is also used in organic synthesis.

[0003] In the prior art, when utilizing methylcyclohexane feedstock gas for profit, dehydrogenation equipment is often required to dehydrogenate it. However, existing dehydrogenation equipment consumes a lot of energy because it directly processes the feedstock gas. It has been verified that preheating the methylcyclohexane feedstock gas can effectively reduce the energy consumption of the dehydrogenation equipment, thereby reducing production costs. Therefore, this application proposes a methylcyclohexane feedstock gas preheating device. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a methylcyclohexane feedstock gas preheating device. The solution includes a preheating cylinder, characterized in that a sleeve is coaxially fixedly connected inside the preheating cylinder, a baffle is fixedly connected to the left side of the inner wall of the sleeve, a gas guide hole is opened on the outer edge of the sleeve located to the left of the baffle, a spiral oil guide pipe is coaxially arranged between the sleeve and the preheating cylinder, an oil storage tank is arranged on the upper side of the preheating cylinder, an overflow assembly is fixedly installed on the inner wall of the oil storage tank, and a connection is fixedly connected to the overflow assembly on the inner wall of the oil storage tank. The heating tank has a corresponding component. A first heating plate arranged horizontally is fixedly connected to the side wall of the heating tank.

A protective plate that abuts against the left end of the first heating plate is fixedly connected to the inner wall of the oil storage tank. An oil outlet hole is opened on the right side wall of the heating tank. The bottom of the oil storage tank is fixedly connected to the inlet end of a heat transfer oil discharge component. The outlet end of the heat transfer oil discharge component is fixedly connected to the inlet end of an oil guide pipe. The outlet end of the oil guide pipe is fixedly connected to the inlet end of a recovery component. The outlet end of the recovery component is connected to the inlet end of the oil tank.

[0005] Preferably, the overflow assembly includes an oil tank that is fixedly connected to the oil storage tank and the heating tank, and the left side wall of the oil tank has an overflow channel corresponding to the heating tank.

[0006] Preferably, the inlet and outlet ends of the oil guide pipe are fixedly connected to the side wall of the preheating cylinder, and the space between the sleeve and the preheating cylinder is a preheating cavity.

[0007] Preferably, the air guide holes are multiple and evenly distributed around the axis of the sleeve.

[0008] Preferably, the heat transfer oil discharge assembly includes an inlet end of a discharge pipe that is fixedly connected to the outlet end of the oil storage tank, an inlet end of a front conveying pipe that is fixedly connected to the outlet end of the discharge pipe, an outlet end of the front conveying pipe that is fixedly connected to the inlet end of the oil guide pipe, and a discharge valve installed on the discharge pipe.

[0010] The beneficial effects of this utility model are: 1. In use, the raw material gas is transported from the left end to the preheating cylinder for preheating, and the preheated raw material gas is discharged from the right end of the preheating cylinder and transported to the dehydrogenation equipment for processing, thereby effectively reducing the energy consumption of the dehydrogenation equipment.

[0011] 2. During preheating, the first and second heating plates are energized to generate a certain amount of heat. An appropriate amount of heat transfer oil is added to the oil tank in the oil reservoir. The heat transfer oil flows from the overflow channel in a thin water curtain shape to the first heating plate in the heating tank, and then flows from the second heating plate to the bottom of the heating tank. The thin heat transfer oil is heated to a certain temperature as it flows through the first and second heating plates. The first heating plate is arranged horizontally, while the second heating plate is arranged obliquely to ensure the heating time of the heat transfer oil, so that the temperature of the heat transfer oil is suitable for preheating the raw material gas.

[0012] 3. After being heated by the first and second electric heating plates, the heat transfer oil enters the oil guide pipe through the discharge assembly. The oil guide pipe then exchanges heat with the raw material gas in the preheating cylinder to achieve the purpose of preheating. The spiral shape of the oil guide pipe ensures the heat exchange effect. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0021] In the first embodiment, the technical solution is as follows: During use, the raw material gas is transported from the left end to the preheating cylinder 1 for preheating. The preheated raw material gas is then discharged from the right end of the preheating cylinder 1 and transported to the dehydrogenation equipment for processing, thereby effectively reducing the energy consumption of the dehydrogenation equipment. During preheating, the first heating plate 9 and the second heating plate 10 are energized to generate a certain amount of heat. An appropriate amount of heat-conducting oil is added to the oil tank 15 in the oil storage tank 6. The heat-conducting oil flows from the overflow channel 16 in a thin, water-like curtain shape to the first heating plate 9 in the heating tank 8, and then flows from the second heating plate 10 to the bottom of the heating tank 8. The thin heat-conducting oil is heated to a certain temperature as it flows through the first heating plate 9 and the second heating plate 10. The first heating plate 9 is arranged horizontally, while the second heating plate 10 is arranged obliquely to ensure sufficient heating time for the heat-conducting oil, making its temperature suitable for preheating the raw material gas. After being heated by the first heating plate 9 and the second heating plate 10, the heat transfer oil enters the oil guide pipe 5 through the discharge assembly. The oil guide pipe 5 then exchanges heat with the raw material gas in the preheating cylinder 1 to achieve preheating. The spiral shape of the oil guide pipe 5 ensures effective heat exchange. A recovery assembly 14 facilitates the recycling of the heat transfer oil.

[0022] In Example 2, based on Example 1, specifically, in this application, the raw material gas enters through the left end of the preheating cylinder 1 for preheating, and then exits from the right end of the preheating cylinder 1 and is sent to the dehydrogenation equipment through corresponding pipelines. This application will not provide a detailed description. The space between the preheating cylinder 1 and the sleeve 2 is a preheating chamber 17. The oil guide pipe 5 is arranged in a spiral shape in the preheating chamber 17. After the raw material gas enters the preheating cylinder 1 from the left end, it enters the preheating chamber 17 through the gas guide hole 4 under the obstruction of the baffle 3. The volume of the preheating chamber 17 is significantly smaller than that of the preheating cylinder 1, and the spiral shape of the oil guide pipe 5 in the preheating chamber 17 can impede the raw material gas to a certain extent. This ensures the effective contact area and contact time between the raw material gas and the heat transfer pipe, ensuring the heat exchange effect between the heat transfer oil and the raw material gas when passing through the heat transfer pipe, thereby guaranteeing the preheating effect.

[0023] During preheating, the drain valve 20 is opened to ensure the drain pipe 18 is unobstructed. Both the first heating plate 9 and the second heating plate 10 are energized and generate high heat. Consequently, the heat transfer oil in the oil tank 15 overflows downwards through the overflow channel 16 in a thin curtain-like manner onto the first heating plate 9. Under the obstruction of the protective plate 11, the heat transfer oil passes relatively evenly through the first heating plate 9 and the second heating plate 10, and then falls downwards to the bottom of the heating tank 8. The horizontally arranged first heating plate 9 and the obliquely arranged second heating plate 10 ensure the contact time between the heat transfer oil and the heating plates, ensuring that it is heated to a certain extent. The heat transfer oil is heated and flows from the oil outlet 12 on the heating tank 8 to the bottom of the oil storage tank 6. Then it enters the oil guide pipe 5 through the discharge pipe 18 and the front conveying pipe 19, and exchanges heat with the raw material gas through the oil guide pipe 5 to achieve the purpose of preheating. After heat exchange, the heat transfer oil flows from the oil guide pipe 5 to the recovery pipe 21, and then is pumped from the recovery pipe 21 to the rear conveying pipe 23 under the action of the conveying pump 22. This allows the heat transfer oil to return to the oil tank 15 through the rear conveying pipe 23 under the action of the conveying pump 22, so as to facilitate the recycling of the heat transfer oil.
