Description

Technical Field

[0001] This utility model relates to the field of boiler exhaust gas treatment technology, and in particular to a desulfurization and dust removal system for boilers. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy.

[0003] Boiler exhaust gas often contains sulfides. To prevent direct discharge and environmental pollution, desulfurization is usually required. Currently, common desulfurization methods often involve ammonia water, using ammonia water or liquid ammonia as an absorbent. This absorbent comes into countercurrent contact with the gas in the desulfurization tower, resulting in an acid-base neutralization reaction that removes the sulfur-containing components from the exhaust gas. While these methods can achieve desulfurization, the flue gas discharged from the boiler also carries a significant amount of dust particles, requiring filtration. Existing filters often use filter plates to adsorb and filter dust. However, as the amount of dust adsorbed increases, the filter pores on the filter plates become clogged, affecting the filtration effect and reducing the efficiency of exhaust gas treatment. Therefore, we propose a desulfurization and dust removal system for boilers. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-3The desulfurization and dust removal system for boilers shown includes an ammonia spray tower 100 and a separator 200. The ammonia spray tower 100 is externally provided with a pipe 500, and a filter structure 300 is externally provided with the pipe 500. The filter structure 300 includes a filter box 301 and a filter plate 302. The filter box 301 is fixedly provided on the outer wall of the pipe 500. A box cover 307 is movably provided on the top of the filter box 301. The filter plate 302 is movably provided in the inner cavity of the filter box 301. A connecting component is provided on the filter plate 302 for connecting and fixing the filter plate 302 and the box cover 307.

[0021] For details, please refer to the following: Figure 1 and Figure 2 In this embodiment, there are two pipes 500, located on one side and one at the top of the ammonia spray tower 100, respectively. The pipe 500 at the top is used to connect the ammonia spray tower 100 to the separator 200. The filter structure 300 is installed on the side pipe 500, allowing the exhaust gas from the boiler to be dusted before entering the ammonia spray tower 100 through the pipe 500. This provides preliminary treatment of the exhaust gas, reducing the number of subsequent treatment steps and improving the effectiveness and efficiency of exhaust gas treatment. The filter plate 302 is connected to the cover 3 via a connecting assembly. 07 Fixed installation: The cover 307 is embedded in the top of the filter box 301. By removing and installing the cover 307, the filter plate 302 can be removed and installed simultaneously. This allows the filter plate 302 to be cleaned of dust residue after a period of use, preventing dust from clogging the filter plate 302, reducing the probability of filter hole blockage, effectively improving the filtration effect of the filter plate 302, and also improving the convenience and flexibility of the filter plate 302's installation and removal. This also provides convenience for the filtration treatment of boiler exhaust gas.

[0022] The connecting assembly includes a connecting plate 303, a connecting rod 304, and a connecting hole 306. The connecting hole 306 is formed on the filter plate 302. The connecting rod 304 is movably disposed on the connecting plate 303. The connecting plate 303 is fixedly disposed at the bottom end of the cover 307. The connecting rod 304 is movably connected to the inner cavity of the connecting hole 306. A spring 305 is fixedly disposed between the connecting rod 304 and the connecting plate 303. The spring 305 is sleeved on the outer wall of the connecting rod 304. The cross-section of the connecting plate 303 is an inverted U-shape, and the cross-section of the connecting rod 304 is T-shaped.

[0023] For details, please refer to the following: Figure 3The connecting plate 303 is fixed to the cover 307 by bolts. The U-shaped design of the connecting plate 303 covers the front and rear positions of the filter plate 302, thus cooperating with the connecting rod 304 to connect the opposite end faces of the filter plate 302. In this embodiment, there are two connecting plates 303, and two connecting rods 304 are installed on each connecting plate 303. The T-shaped design of the connecting rods 304 facilitates the operator to pull the connecting rods 304 and provides a force structure for the movement of the connecting rods 304. The inner cavity of the connecting hole 306 is connected to the opposite end face of the filter plate 302. Therefore, there is one connecting hole 306 under the two connecting rods 304. Through the connection between the connecting rod 304 and the connecting hole 306, the filter plate 302 can be connected to the cover 307. Therefore, when the cover 307 is removed from the filter box 301, the filter plate 302 can be moved out of the inner cavity of the filter box 301 simultaneously, effectively improving the efficiency of disassembling and assembling the filter plate 302. At the same time, the connection between the connecting rod 304 and the connecting plate 303 is through the spring 305. Under the setting of the spring 305, the connecting rod 304 can be connected to the connecting plate 303, and can also move laterally under the action of external force. Thus, after the filter plate 302 is taken out of the filter box 301 along with the cover 307, the connecting rod 304 can be pulled to separate the connecting rod 304 from the connecting hole 306, so that the filter plate 302 can be quickly removed separately. This allows the filter plate 302 to be cleaned and replaced separately, further improving the flexibility of disassembling, assembling and cleaning the filter plate 302.

[0024] The outer wall of the filter box 301 is provided with a driving structure 400, which includes a driving component 401, a support plate 402 and an adsorption assembly. The driving component 401 is fixedly disposed on the top of the support plate 402, and the support plate 402 is fixedly disposed on the outer wall of the filter box 301. The adsorption assembly is disposed between the driving component 401 and the box cover 307. The adsorption assembly includes a movable plate 403, a vacuum pump 404 and a suction cup 405. The vacuum pump 404 is fixedly disposed on the top of the movable plate 403, and the suction cup 405 is connected to the vacuum pump 404. The movable plate 403 is fixedly disposed on the top of the driving component 401.

[0025] For details, please refer to the following: Figure 1 and Figure 2The driving component 401 can be either an electric telescopic rod or a cylinder. The driving component 401 is mounted and stabilized on the filter box 301 via the support plate 402. The top of the driving component 401 is connected to the movable plate 403. The movable plate 403 moves vertically by the drive of the driving component 401. The vacuum pump 404 and the driving component 401 are both electrically connected to an external power supply via an external switch. The suction cup 405 is located below the movable plate 403. The suction cup 405 can perform vacuum adsorption through the vacuum pump 404. Thus, the suction cup 405 adsorbs the cover 307, allowing the cover 307 to move with the position of the suction cup 405. This allows the cover 307 to be flexibly disassembled and assembled with the filter box 301, facilitating the disassembly and assembly of the cover 307 and improving the efficiency of disassembly and cleaning of the filter plate 302.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
