DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1 and Figure 2 A benzene raw material feed preheating device comprises a benzene raw material preheating device body 1, the outside of the benzene raw material preheating device body 1 is fixedly connected with an exhaust pipe 2 for exhaust, and a filtering structure is arranged at the top of the exhaust pipe 2; the filtering structure comprises a filter box 3, a first filter plate 5 and a second filter plate 6 detachably mounted inside the filter box 3; a mounting seat 10 slidably connected to the first filter plate 5 and the second filter plate 6 is arranged inside the filter box 3, and a fixing piece connected to the mounting seat 10 is arranged inside the first filter plate 5 and the second filter plate 6.

[0026] In this embodiment, a cavity 4 is provided inside the filter box 3, and there are four mounting seats 10, and the four mounting seats 10 are symmetrically installed in groups of two between the left and right inner walls of the cavity 4. The second filter plate 6 and the first filter plate 5 are distributed up and down and slidably installed between the four mounting seats 10 and fixed by fixing members.

[0027] The second filter plate 6 is an activated carbon filter plate, which can filter the gas, and avoid the raw materials being discharged into the air with the tail gas to cause air pollution. A condenser 9 is installed inside the filter box 3, and the condenser 9 can cool the gas and keep it in reserve, so as to facilitate the subsequent discharge of the gas into the benzene raw material preheating device body 1. The upper surface of the filter box 3 is fixedly connected to a cover body 7, and the upper surface of the cover body 7 is fixedly connected to an air duct 8, and the other end of the air duct 8 is connected to an air duct device.

[0028] It should be noted that the benzene raw material preheating device body 1 is a conventional technology known to the public in the prior art, so the specific structure and working principle thereof will not be described in detail in this article. An inspection plate for sealing the cavity 4 is detachably installed on the outside of the filter box 3, so as to facilitate the subsequent inspection of the first filter plate 5 and the second filter plate 6.

[0029] Embodiment 2:

[0030] See also Figure 3 and Figure 4 On the basis of the first embodiment, the fixing member includes a sleeve 11, a reset spring 13 disposed inside the sleeve 11, and a clamping block 14 fixedly mounted at both ends of the reset spring 13 and extending to the outside of the sleeve 11 and clamping with the mounting seat 10. The sleeve 11, the mounting seat 10, the first filter plate 5, and the second filter plate 6 are provided with a perforation 15, and the two clamping blocks 14 extend to the outside of the sleeve 11 through the perforation 15 and penetrate the inside of the mounting seat 10, the first filter plate 5, and the second filter plate 6.

[0031] The sleeve 11 has a mounting groove 12 in communication with the through hole 15, and a guide member for limiting the two clamping blocks 14 is arranged in the mounting groove 12. The guide member includes a guide rod 16 fixedly mounted on the inner wall of the mounting groove 12 on the opposite side and penetrating the two clamping blocks 14. The two clamping blocks 14 are both provided with a sliding sleeve 17 sleeved on the outside of the guide rod 16. By installing the guide member, the linear displacement of the two clamping blocks 14 is ensured, the extrusion of the reset spring 13 is improved, the reset spring 13 is stably deformed, and the installation effect is improved.

As the first filter plate 5 or the second filter plate 6 moves, until the first filter plate 5 or the second filter plate 6 abuts against the end of the mounting seat 10, the return spring 13 stops deforming, so that the block 14 is inserted into the hole 15 to achieve installation and fixation, which facilitates the disassembly and assembly of the first filter plate 5 or the second filter plate 6.

[0034] The working principle of the above embodiment is:

[0035] When in use, the benzene raw material is preheated by the benzene raw material preheating device body 1. When exhaust gas needs to be discharged, the exhaust gas in the benzene raw material preheating device body 1 is extracted by the air intake device at one end of the air intake pipe 8. The gas enters the filter box 3 and is filtered by the first filter plate 5 and the second filter plate 6, thereby preventing the raw material from being discharged into the air with the exhaust gas and causing air pollution. At the same time, the condenser 9 can cool the gas and keep it in reserve, thereby preventing the raw material from being discharged into the air with the exhaust gas and causing air pollution.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
