Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical tail gas treatment, in particular to an environmentally friendly petrochemical tail gas purification treatment device. Background Art

[0002] Petrochemical is the abbreviation of petrochemical industry, also known as petrochemical industry. During production, petrochemical industry often produces exhaust gas containing a variety of harmful substances. These exhaust gases may contain sulfur oxides, nitrogen oxides, volatile organic compounds, particulate matter and other toxic and harmful gases. However, when the existing exhaust gas treatment equipment treats the dust inside the exhaust gas, the dust will adhere to the inner wall and damage the inner wall, making it inconvenient to clean.

[0003] In order to solve the above problems, the announcement number CN211753850U discloses "a petrochemical tail gas treatment device" which starts the generator, then the generator rotates and generates current and transmits the current to the inside of the vibrator, then the vibrator works and generates vibration force, then the vibration force is transmitted to the inside of the filter chamber through the outer shell, and acts on the inner wall of the filter chamber, and at the same time, the vibration on the inner wall will fall, which can ensure the cleanliness of the inside of the outer shell and facilitate the collection and treatment of dust. However, the device still has certain defects in actual use. This device adopts Vibration cleaning is very simple to operate, has a simple mechanical structure, and is very reliable when running. However, if the vibration intensity is too small, the cleaning effect is not very strong. If the vibration intensity is too large, the connections of the internal components will become loose, or even damaged. At the same time, this device uses adsorption filtration to adsorb harmful gases in the exhaust gas. However, the adsorption capacity of the filter is limited. After saturation, it needs to be replaced or regenerated in time. However, when replacing this device, the outer shell needs to be removed, and then the filter needs to be removed for replacement, which is time-consuming, labor-intensive and inefficient.

[0024] The following is a detailed description of the environmentally friendly petrochemical tail gas purification device. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] See also Figure 1-6 In the embodiment, an environmentally friendly petrochemical tail gas purification treatment device is provided, including: a filter box 1, one side of the filter box 1 is fixedly connected to an intake pipe 11, a plurality of filter plates 12 are arranged inside the intake pipe 11, a plurality of connecting rods 13 are fixedly installed on the other side of the filter box 1, one end of the plurality of connecting rods 13 is fixedly connected to a desulfurization box 14, a cleaning component, the cleaning component is arranged inside the filter box 1, and is used to clean the dust on the inner wall of the filter box 1, and a disassembly component is arranged inside the intake pipe 11, so as to facilitate the replacement of the filter plate 12.

[0028] Example 2

[0029] On the basis of Example 1, the cleaning assembly includes: a rotating rod 2 arranged inside the filter box 1, a driving motor 21 is fixedly installed on the side of the filter box 1 away from the air inlet pipe 11, the driving shaft of the driving motor 21 is connected to the rotating rod 2, a sleeve 22 is arranged on the outside of the rotating rod 2, two symmetrically arranged mounting plates 23 are arranged on the outside of the sleeve 22, and a plurality of cleaning brushes 24 distributed at equal intervals are fixedly installed on the outside of the two mounting plates 23, and the plurality of cleaning brushes 24 are distributed in a spiral structure, and a plurality of symmetrically arranged sliding sleeves 25 are fixedly connected to the opposite sides of the outside of the sleeve 22, and a piston rod 26 is slidably connected inside the plurality of sliding sleeves 25, and one end of the piston rod 26 is connected to the mounting plate 23, two hubs 27 are fixedly installed on the outside of the sleeve 22, and a plurality of fan blades 28 are fixedly installed on the outside of the two hubs 27, and a plurality of air outlet holes 29 are provided on the side of the filter box 1 away from the air inlet pipe 11.

[0030] When treating petrochemical tail gas, the tail gas discharge pipe is connected to the intake pipe 11, and the tail gas continuously enters the filter plate 12 inside the intake pipe 11 to filter and absorb harmful gases, and then enters the filter box 1. A small amount of dust is entrained in the filtered tail gas, and the dust will adhere to the inner wall of the filter box 1. The drive motor 21 is started. After the drive motor 21 is started, the rotating rod 2 is driven to rotate, and the rotating rod 2 drives the sleeve 22 and the sliding sleeve 25 to rotate at the same time. The centrifugal force generated during the rotation causes the piston rod 26 inside the sliding sleeve 25 to be pushed out, and the piston rod 26 is pushed out so that the mounting plate 23 and the filter are connected. The inner wall of the filter box 1 fits together, and the cleaning brush 24 is driven to rotate when the mounting plate 23 rotates. Since the cleaning brush 24 is distributed in a spiral structure, the upper and lower cleaning brushes 24 can evenly cover the inner wall of the filter box 1 during rotation, and the dust on the inner wall of the filter box 1 is cleaned off by continuous brushing. At the same time, the sleeve 22 rotates while driving the hub 27 to rotate, and the hub 27 drives the fan blades 28 to rotate. The rotation of the fan blades 28 generates suction, and then the cleaned dust can be transported to one side and discharged through the air outlet 29 for the next step of processing, so that the dust on the inner wall of the filter box 1 can be cleaned.

[0031] Among them, multiple connecting rods 13 are externally slidably connected to two positioning plates 4, and mounting holes 41 are respectively opened on the two positioning plates 4.

One end of the connecting pipe 42 is connected to the air outlet 29, and the other end of the connecting pipe 42 is connected to the desulfurization box 14. An exhaust hole 43 is arranged on one side of the desulfurization box 14.

[0032] The adsorbed and filtered gas is discharged from the air outlet 29 and enters the connecting pipe 42, and then enters the desulfurization box 14 along the connecting pipe 42 for the next step of treatment, so as to purify the petrochemical tail gas. After the treatment, the gas is discharged into the air through the exhaust hole 43. The positioning plate 4 can support the connecting pipe 42 to prevent the connecting pipe 42 from contacting the drive motor 21, effectively preventing heat conduction, and preventing the connecting pipe 42 from being melted and deformed by the heat generated by the drive motor 21.
