Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plaster processing, in particular to a novel plaster waste gas purification tower. Background Art
[0002] Plaster waste gas purification towers are used to treat waste gas generated during the plaster production process. Plaster waste gas may contain pollutants such as particulate matter, oil smoke, organic matter, acidic or alkaline substances, and odor. The waste gas purification tower removes these pollutants through a series of treatment processes to meet environmental emission standards.
[0003] When the plaster waste gas purification tower is in operation, the final emission of flue gas is completed through the exhaust pipe. Although the purification tower has undergone a series of treatment processes, there may still be some fine particles that have not been completely removed. Therefore, it is necessary to install a filter on the exhaust pipe, which can act as an additional line of defense to capture residual particles and thus improve the cleanliness of the exhaust gas. However, in general, only one interception net is installed in the exhaust pipe. Since there is only this one interception net, when it is blocked, there is no backup filtering path, and the entire system must wait until the interception net is cleaned before it can resume normal operation. During this period, it may take a long time, resulting in greater economic losses and time costs. Based on this, a new type of plaster waste gas purification tower came into being. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new type of plaster waste gas purification tower.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Reference Figure 1-4The new plaster waste gas purification tower comprises a purification tower body 1, a base 2, a mounting cover 3, and an exhaust pipe 4. The purification tower body 1 is also equipped with an air inlet pipe. The purification tower body 1 is a conventional product and generally operates as follows: Exhaust gas enters the purification tower body 1 through the air inlet pipe. Driven by a fan, it rapidly fills the air inlet section and then evenly rises through the flow-balancing section to the various levels of filler absorption sections. On the filler surface, pollutants in the gas phase chemically react with absorbents in the liquid phase. For example, in some purification tower bodies 1, alkaline spraying may be used to remove particulate matter and some oil smoke from the exhaust gas. Surfactants, acid solutions, plant extracts, and other agents are then used to further remove various pollutant components. Unabsorbed gas continues to rise and undergoes multiple stages of treatment. In the spray section, the absorption liquid is sprayed at high speed from uniformly distributed nozzles, forming countless fine droplets that mix thoroughly with the gas, allowing the chemical reaction to continue. This process also involves heat and mass transfer. Controlling the superficial tower flow rate and residence time ensures a sufficient and stable reaction. Finally, a demisting section is provided at the top of the purification tower body 1 to remove liquid droplets entrained in the gas, achieving gas-liquid separation. The purified clean air is then discharged into the atmosphere through exhaust pipe 4. In the above description, the internal equipment components are not shown in this solution. For details, please refer to the existing technology. This solution only improves the exhaust pipe 4.
[0022] A screw 7 is provided on the mounting cover 3 through two fixing plates 6, one of the fixing plates 6 is provided with a power mechanism connected to the screw 7, a nut 9 is threadedly sleeved on the screw 7, a connecting plate 11 is provided on the nut 9 through a connecting mechanism, two matching openings 12 are provided on the connecting plate 11, and interception nets 13 are provided in the two matching openings 12, an insertion rod 14 is provided on the connecting plate 11 through an elastic mechanism, an insertion channel corresponding to the insertion rod 14 is provided on the interception net 13, and a slot corresponding to the insertion rod 14 is provided on the inner wall of the matching opening 12.
[0023] The power mechanism includes a drive motor 8 installed on the fixed plate 6. The output shaft of the drive motor 8 rotates through the fixed plate 6 and is fixedly connected to the end of the screw 7. The drive motor 8 is the power device of the screw 7. The drive motor 8 is arranged outside the purification tower body 1. Its exposed design can ensure a good heat dissipation environment during operation, and is convenient for daily maintenance, inspection, and replacement of the drive motor 8.
[0024] The connecting mechanism includes a connecting block 18 mounted on the connecting plate 11, and a connecting groove corresponding to the connecting block 18 is provided on the outer wall of the nut 9. As shown in the figure, the vertical cross-section of the connecting plate 11 is L-shaped, and the place where it contacts the nut 9 is designed as an arc-shaped recess. The above-mentioned connecting block 18 is arranged on the inner wall of the arc-shaped recess. Since the structure of the connecting block 18 is known, the connecting groove and its corresponding design are associable and are not drawn in the figure.
[0025] The elastic mechanism includes a spring 15 sleeved on the outside of the insertion rod 14, and an anti-slip block is provided at the end of the insertion rod 14. The two ends of the spring 15 are elastically connected to the outer wall of the connecting plate 11 and the outer wall of the anti-slip block respectively. The elastic potential energy provided by the spring 15 realizes the dragging of the anti-slip block, so that the insertion rod 14 slides through the connecting plate 11 and enters the matching port 12. At the same time, the end is in the slot on the inner wall of the matching port 12 and passes through the insertion channel on the interception net 13. The vertical cross-sectional views of the above-mentioned insertion rod 14, slot and insertion channel are all regular hexagons, so the interception net 13 cannot rotate in the matching port 12, ensuring its stability when installed in the matching port 12.
[0026] A limiting rod 10 is provided between the two fixing plates 6. The limiting rod 10 slides through the nut 9. The function of the limiting rod 10 is to limit the nut 9 to prevent it from rotating with the screw 7. Therefore, when the screw 7 rotates, the nut 9 will not rotate and will move.
[0027] A groove 16 is provided on the upper end surface of the mounting cover 3, and a staggered opening 17 is provided on the connecting plate 11. The groove 16 facilitates the connecting plate 11 to fall into it, thereby disengaging the connecting block 18 from the connecting groove. The staggered opening 17 is designed to enable the connecting plate 11 to descend, at which time the exhaust pipe 4 is in the staggered opening 17.
[0028] When the present invention is in use, the waste gas from the plaster enters the purification tower body 1 through the air inlet pipe for purification, and is finally discharged through the exhaust pipe 4. The interception is completed with the help of the interception net 13 in the matching port 12. When the mesh of the current interception net 13 is seriously clogged, start the drive motor 8 to drive the screw 7 to rotate. When the screw 7 rotates, the nut 9 drives the connecting plate 11 to move, so that another interception net 13 is moved to the connecting port 5, and the interception net 13 with more serious blockage will be removed, and it can be cleaned and wait for standby. If the blockage is very serious, at this time, drag the insertion rod 14 to separate it from the interception net 13, and then try to disassemble the interception net 13, disassemble it, rinse it, and then install it again.
[0029] The driving motor 8 continues to rotate, and the connecting plate 11 will continue to move. When the staggered opening 17 corresponds to the exhaust pipe 4, the connecting plate 11 has moved to the position of the groove 16. At this time, the connecting plate 11 falls into the groove 16 and disengages from the nut 9. Then the connecting plate 11 is moved horizontally to disengage from the groove 16. At this time, the exhaust pipe 4 is still in the staggered opening 17. The connecting plate 11 is lifted up to disengage from the exhaust pipe 4 to complete the disassembly of the connecting plate 11 and other components. The entire component can be easily disassembled for maintenance, inspection or replacement without the need for complicated operations on the purification tower body 1, reducing the difficulty and risk of operation.
[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
