[0002] During the coal chemical production process, SO2 is generated and mixed in the waste gas. When the waste gas needs to be discharged, it needs to be desulfurized before it can be discharged. When treating the waste gas, a waste gas desulfurization device is needed. When the existing waste gas desulfurization device is in use, since the waste gas contains a large amount of solid particles, the waste gas generally needs to be dusted first and then discharged into the desulfurization tower.

After long-term use, the dust particles are easy to clog the filter screen. The staff may not be able to find and clean it in time, resulting in reduced exhaust efficiency and affecting the desulfurization efficiency of the device. For this reason, we propose a coal chemical desulfurization device. Utility Model Content

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

[0024] Example 1

[0025] See also Figures 1 to 6 The utility model provides a technical solution: a coal chemical desulfurization device, comprising a gas dust removal mechanism 1 and a desulfurization tower device 2, wherein the gas dust removal mechanism 1 and the desulfurization tower device 2 are commonly connected by a connecting pipe 3;

[0026] The gas dust removal mechanism 1 includes a dust removal box 11 and a cleaning assembly 12. A filter plate 13 is installed inside the dust removal box 11, the connecting pipe 3 is located at the bottom of the filter plate 13, and the cleaning assembly 12 is located at the top of the filter plate 13. Two symmetrical through grooves 14 are provided inside the filter plate 13, and a collecting frame 15 is slidably connected at the bottom of the filter plate 13 and located at the position of the through groove 14. Two symmetrical notches 16 are provided inside the dust removal box 11, and sealing gaskets 17 are provided inside the two notches 16. One end of the collecting frame 15 is located inside the sealing gasket 17. An air inlet pipe 18 is provided on one side of the top of the dust removal box 11, and the air inlet pipe 18 is located on the top of the filter plate 13. A box cover 19 is provided on the top of the dust removal box 11. A dust concentration sensor 110 and a control device 111 are respectively installed on one side of the outside of the dust removal box 11. A transparent observation window 112 is provided on one side of the dust removal box 11 and located at the bottom of the dust concentration sensor 110 and the control device 111;

[0027] The cleaning assembly 12 includes a protective cover 121 installed on the outside of the dust removal box 11, a motor 122 is installed inside the protective cover 121, a fixed seat 123 is installed inside the dust removal box 11, a screw rod 124 is connected to the inside of the fixed seat 123, the power drive end of the motor 122 is connected to the screw rod 124, the connection between the screw rod 124 and the fixed seat 123 is movably connected through a bearing, and a movable seat 125 is connected to the outside of the screw rod 124, a limiting plate 126 is installed on the top of the movable seat 125, and a limiting groove 127 is provided on one side of the interior of the fixed seat 123. The limiting plate 126 is located inside the limiting groove 127 and is a sliding connection structure. A cleaning brush 128 is installed at the bottom of the movable seat 125, and the cleaning brush 128 is located on the top of the filter plate 13. One side of the cleaning brush 128 is slidably connected to the inside of the dust removal box 11.

[0028] Exhaust gas enters the dust removal box 11 from the air inlet pipe 18, and dust particles in the exhaust gas are filtered through the filter plate 13. The clean gas after filtration is transported from the connecting pipe 3 to the desulfurization tower device 2 for desulfurization. The dust detection value of the dust concentration sensor 110 is adjusted by the setting of the control device 111. When the dust concentration sensor 110 detects that the dust in the dust removal box 11 reaches a certain value, the cleaning component 12 is activated to clean the filter plate 13. The staff can also observe the situation in the dust removal box 11 through the transparent observation window 112 to prevent excessive dust from clogging the filter plate 13.

[0029] When the cleaning assembly 12 cleans the filter plate 13, the motor 122 is operated, and the motor 122 drives the screw rod 124 to rotate. Through the setting of the limit plate 126 and the limit groove 127, the movable seat 125 is located inside the fixed seat 123 and moves linearly. At this time, the movable seat 125 drives the cleaning brush 128 to move on the top of the filter plate 13. The cleaning brush 128 cleans the filter plate 13 back and forth to prevent dust particles from clogging the filter plate 13 and improve the filtering effect. After rotating for a certain period of time, the motor 122 rotates in the opposite direction, so that the movable seat 125 drives the cleaning brush 128 to move back and forth;

[0030] The motor 122 can be set through programming, which is an existing well-known technology and will not be described in detail here; the working principle of the dust concentration sensor 110 is: the external air enters the sensor darkroom through the maze-type air inlet under the suction of the exhaust fan; when the suspended dust in the air is irradiated by the parallel light emitted by the laser generator in the darkroom, the scattered light intensity of the dust is proportional to the mass concentration, and the scattered light is converted into a photocurrent by the photoelectric converter, and converted into a photoelectric pulse number proportional to the scattered light intensity by the photocurrent integration circuit of the main control board; the relative mass concentration of the dust can be measured by calculating the number of pulses, and the K value is preset on the setting keyboard by calibration, and the dust mass concentration (mg / m3) in the air can be directly displayed on the digital display screen during operation.

[0031] Example 2

[0032] like Figures 1 to 6 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the cleaning brush 128 is located on the top of the filter plate 13 and moves back and forth to clean the dust particles on the filter plate 13 to the position of the two through grooves 14. The dust particles fall into the two collection frames 15 through the two through grooves 14. When cleaning the dust particles in the collection frames 15 later, the user only needs to hold the handle set on the front side of the collection frame 15 and pull the collection frame 15 out of the sealing gasket 17. At this time, the dust and particles in the collection frame 15 can be cleaned. The setting of the sealing gasket 17 increases the tightness of the connection between the collection frame 15 and the slot 16.
