AI Technical Summary
After the primary oxidized homoanhydride trap is operated for a period of time, the homoanhydride is enriched on the trap spring, and it is impossible to effectively remove homoanhydrides from vertical, vertebral and horizontal connection parts of the container wall. Traditional methods such as hitting with a hammer is not obvious and labor-consuming and time-consuming.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of trap clogging removal equipment, in particular to a trap clogging removal equipment. Background Technique
[0002] The original capture of pyromellitic dianhydride is usually an important link in its production process. The following is the general working principle and related process:
[0003] In the production of pyromellitic dianhydride, usually 1,2,4,5-tetramethylbenzene and air are used as the main raw materials. Under the action of a catalyst (such as vanadium pentoxide, etc.), pyromellitic dianhydride is generated through an oxidation reaction. The capture principle is that the product after the oxidation reaction contains pyromellitic dianhydride gas. The capture process mainly utilizes the characteristics of pyromellitic dianhydride to sublime or condense from the gas phase under certain conditions (such as temperature, pressure, etc.). Through appropriate cooling or temperature reduction means, the pyromellitic dianhydride gas is condensed into a solid state, so as to realize the separation and capture of pyromellitic dianhydride from the reaction product.
[0004] After the original pyromellitic dianhydride trap has been operating for a period of time, pyromellitic dianhydride accumulates on the trap spring. The method of manually or electrically shaking the spring is used to remove the pyromellitic dianhydride accumulated on the spring, but the pyromellitic dianhydride on the vertical container wall, the conical part and the horizontal connection part cannot be effectively removed. The common method is to knock with a hammer, but the effect is not obvious and it is laborious and time-consuming. Content of the Utility Model

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , the present utility model provides a clogging removal device for a trap, including a connecting pipe 8. A fourth sonic soot blower 4 is fixedly installed at the top of the connecting pipe 8, and a fifth sonic soot blower 5 is fixedly installed at the bottom of the connecting pipe 8. At the same time, three groups of connected trap bodies 6 are sequentially installed on the upper left side of the connecting pipe 8, and three groups of connected trap bodies 6 are sequentially installed on the lower left side of the connecting pipe 8. Spring frames 7 are installed inside multiple groups of trap bodies 6. At the same time, the two trap bodies 6 are connected through a branch pipe, and a second sonic soot blower 2 is installed on the branch pipe. A first sonic soot blower 1 and a third sonic soot blower 3 are respectively installed on the two trap bodies 6.
[0023] Working principle: The fourth sonic soot blower 4 and the fifth sonic soot blower 5 are respectively fixedly installed at the top and bottom of the connecting pipe 8; the first sonic soot blower 1 and the third sonic soot blower 3 can perform sonic vibration work on the inside of the trap body 6; the specific working mode of the sonic soot blower is: using compressed air or nitrogen as the power source, the energy of the sound wave causes the adhesion state of the accumulated material on the surface of the equipment wall to be separated, and the original accumulated material undergoes fatigue fracture and fragmentation; under the action of the sound wave, the accumulated material is peeled off from the surface of the equipment wall and is caused to fall off by the gas flowing at a certain flow rate and gravity; relying on the sound wave oscillation and sound fatigue to achieve the purpose of soot cleaning. The role of oscillation is to prevent the material from adhering to the cooling surface, and the role of sound fatigue is to cause the dust adhering to the heated surface to be peeled off from the equipment surface through fatigue; adopting the method of sonic powder cleaning to replace the method of manually knocking the equipment wall to clean the powder, relying on the impact force of the working medium to gradually remove the accumulated material bit by bit. The sound wave directly acts on the surface of the material, thus eliminating the loss of the equipment caused by the traditional manual knocking method.
[0024] As a preferred implementation manner, the first sonic soot blower 1 includes a packing sleeve 14 fixed to the top of the trap body 6, and a sleeve flange 12 is welded to the top of the packing sleeve 14. At the same time, a mating flange 11 covers the surface of the sleeve flange 12.
[0025] The middle of the mating flange 11 is welded to the upper side of the sonic duct 15, and a sonic generator is installed at the top of the sonic duct 15. At the same time, the mating flange 11 and the sleeve flange 12 are fixed through multiple groups of bolts.
[0026] A gasket 13 is fixedly installed on the outer side of the stuffing sleeve 14, and the stuffing sleeve 14 is inserted through the opening at the top of the trap body 6 and sealed by the gasket 13.
[0027] As a preferred embodiment, an isolation mesh 17 is installed at the bottom of the acoustic waveguide 15, and a plurality of groups of filter holes are evenly formed on the surface of the isolation mesh 17. At the same time, three positioning pieces 16 are evenly and fixedly arranged on the outer side of the isolation mesh 17.
[0028] The sizes of the positioning pieces 16 and the positioning grooves 161 are adapted to each other. There are three groups of positioning grooves 161, and the three groups of positioning grooves 161 are evenly formed in the circumferential position of the inner wall at the bottom of the acoustic waveguide 15. At the same time, the positioning pieces 16 are clamped inside the positioning grooves 161 and fixed by bolts.
[0029] As Figures 1-4 shown: The isolation mesh 17 is positioned and installed at the bottom of the acoustic waveguide 15 on the first acoustic soot blower 1 through the positioning pieces 16 and the positioning grooves 161. The setting of the isolation mesh 17 can effectively prevent foreign matters such as dust, impurities, and debris from entering the interior of the acoustic soot blower. For example, in some industrial sites with relatively harsh environments, there may be a large number of fine particles. Without a filter screen, these particles are likely to enter the soot blower and affect its normal operation.
[0030] It can avoid large particles from impacting and wearing the internal sound generating elements, vibrating components, etc., and extend the service life of the acoustic soot blower. The isolation mesh 17 can intercept most of the pollutants outside, so that during maintenance and cleaning, only the filter screen and the pollutants on its surface need to be processed, rather than performing complex cleaning work on the entire interior of the soot blower.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
