DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The present invention provides a benzene compound continuous evaporation device, which belongs to the field of chemical equipment. The benzene compound continuous evaporation device is used to heat benzene compounds, benzene compound ethers, etc., and then the material can be heated by the benzene compound continuous evaporation device to generate material vapor. The benzene compound continuous evaporation device can be used to preheat the material before replenishing the material, avoiding interruption of material vapor after replenishing the material.

[0023] In some preferred embodiments, the benzene compound continuous evaporation device includes an evaporation component 100 and a preheating component 200. The evaporation component 100 includes a first furnace body 110 and a first heating element 120. The top of the first furnace body 110 is provided with an air guide port 111, and the first furnace body 110 is also provided with an inlet port 112. The first heating element 120 is built into the first furnace body 110 and is used to heat the material in the first furnace body 110. The preheating component 200 includes a second furnace body 210, a second heating element 220 and a stop valve 230. The second furnace body 210 is provided with a feed port 211 and a discharge port 212. The discharge port 212 is connected to the inlet port 112. The second heating element 220 is built into the second furnace body 210 and is used to heat the material in the second furnace body 210. The stop valve 230 is installed between the discharge port 212 and the inlet port 112 to close or open the material passage between the discharge port 212 and the inlet port 112.

[0024] In the above embodiment, the stop valve 230 is first closed, and the material in the first furnace body 110 is heated by the first heating element 120. The material in the first furnace body 110 is heated, and the material vapor generated by the evaporation of the material is discharged from the outlet 212. When it is necessary to replenish the material in the first furnace body 110, the material can be first put into the second furnace body 210. Under the heating effect of the second heating element 220, the material in the second furnace body 210 is heated. When the temperature in the second furnace body 210 is equal to the temperature in the first furnace body 110, the stop valve 230 can be opened to introduce the material in the second furnace body 210 into the first furnace body 110, and then the material replenishment in the first furnace body 110 can be completed. By using the continuous evaporation device for benzene compounds provided by the utility model, the material can be preheated before replenishing the material in the first furnace body 110. Therefore, after the new material enters the first furnace body 110, the temperature in the first furnace body 110 will not drop, ensuring that the first furnace body 110 can continuously generate material vapor, avoiding interruption of material vapor after replenishing the material.

[0025] If the pressure in the first furnace body 110 is higher than that in the second furnace body 210, it will make it difficult to introduce the material in the second furnace body 210 into the second furnace body 210. In some preferred embodiments, the preheating assembly 200 also includes an introduction pump 240, which is arranged between the introduction port 112 and the outlet port 212 to pressurize the material in the second furnace body 210 into the first furnace body 110.

[0026] In the above embodiment, after the stop valve 230 is opened, the material in the second furnace body 210 can be introduced into the first furnace body 110 by the introduction pump 240, and then under the pressure of the introduction pump 240, it can be ensured that the material in the second furnace body 210 can be smoothly introduced into the first furnace body 110.

[0027] Based on the above embodiments, in some preferred embodiments, the preheating assembly 200 further includes a one-way valve 250, which is installed between the introduction pump 240 and the introduction port 112. The one-way valve 250 can be used to prevent the material in the first furnace body 110 from flowing back into the second furnace body 210.

[0028] Any implementation method that can heat the material in the second furnace body 210 is feasible. In some preferred embodiments, the second heating element 220 includes an electric heating plate 221, which is installed at the bottom of the second furnace body 210 and emits heat to heat the material in the second furnace body 210. Since the second furnace body 210 only serves as a preheating function, the evaporation rate of the material does not need to be considered, and therefore only the electric heating plate 221 with a simple structure can be used.

[0029] Any implementation method is feasible as long as the material in the first furnace body 110 can be heated. In some preferred embodiments, the first heating element 120 includes a plurality of electric heating rods 121, which are vertically arranged in the first furnace body 110 to heat the material in the first furnace body 110. The use of a plurality of vertically arranged electric heating rods 121 can make the material in the first furnace body 110 evaporate quickly.

[0030] Based on the above embodiments, in some preferred embodiments, the outer periphery of the electric heating rod 121 has a plurality of heat sinks 1211. The heat sinks 1211 are used to increase the heating area of ​​the material, so that the material in the first furnace body 110 can evaporate quickly, thereby increasing the evaporation speed of the material.

[0031] In some preferred embodiments, a water vapor port 213 is provided at the top of the second furnace body 210, and a water vapor valve 214 is installed at the water vapor port 213. As the material is heated in the second furnace body 210, water vapor will be continuously generated, and water will be vaporized first due to its low boiling point. At this time, the water vapor valve 214 can be opened to discharge the water vapor.

[0032] In some preferred embodiments, the outlet 212 is located at the bottom of the second furnace body 210 to facilitate complete outlet of the materials in the second furnace body 210 .

[0033] In some preferred embodiments, the first furnace body 110 has a conical guide plate surrounding the outlet 212, so that the material vapor in the first furnace body 110 can be more smoothly discharged through the conical guide plate.

[0034] In some preferred embodiments, the first furnace body 110 and the second furnace body 210 are both metal furnace bodies, so that the first furnace body 110 and the second furnace body 210 have sufficient structural strength.

[0035] First, the stop valve 230 is closed, and a plurality of vertically arranged electric heating rods 121 are used to quickly evaporate the material in the first furnace body 110. The material in the first furnace body 110 is heated, and the material vapor generated by the evaporation of the material will be discharged from the outlet 212. When it is necessary to replenish the material in the first furnace body 110, the material can be first put into the second furnace body 210, and the electric heating plate 221 is installed at the bottom of the second furnace body 210, and the electric heating plate 221 emits heat to heat the material in the second furnace body 210. The material in the second furnace body 210 is heated. When the temperature in the second furnace body 210 is equal to the temperature in the first furnace body 110, the stop valve 230 can be opened. Under the pressure of the introduction pump 240, it can be ensured that the material in the second furnace body 210 can be smoothly introduced into the first furnace body 110. Then, the material replenishment in the first furnace body 110 can be completed. By using the continuous evaporation device for benzene compounds provided by the utility model, the material can be preheated before replenishing the material into the first furnace body 110. Therefore, after the new material enters the first furnace body 110, the temperature inside the first furnace body 110 will not drop, ensuring that the first furnace body 110 can continuously generate material vapor and avoiding interruption of material vapor generation after replenishing the material.

[0036] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
