Description

Technical Field

[0001] The utility model relates to the field of dust removal equipment, and more specifically, to a cyclone dust removal device for a hot blast stove. Background Art

[0002] Hot blast stoves are widely used and are now widely used as heat sources in tobacco, vegetables and other agricultural product baking houses. Its working principle is as follows: fuel is conveyed to the furnace of the hot blast stove through a feeding device for combustion, the smoke and fire pass through the heat exchange pipes of the heat exchanger and then are discharged through the smoke pipes. There is wind outside the heat exchange pipes to generate hot air, and the hot air is conveyed to the baking house to provide heat for the baking work. Since a large amount of dust is generated after the fuel is burned, a dust remover is usually used to perform dust removal operations on the air after heat exchange. Currently, the commonly used dust remover is a cyclone dust remover. Although it can remove dust, due to the relatively light mass of dust particles in the flue gas, an ordinary cyclone dust remover cannot remove dust well. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0004] A cyclone dust removal device for a hot blast stove, which includes a dust removal device body. The dust removal device body includes a cyclone cylinder. A cloth bag mounting bracket is arranged in the cyclone cylinder. The cloth bag mounting bracket is sleeved with a cloth bag cylinder with an opening downward. A discharge port is arranged at the top end of the cyclone cylinder. A cover plate is arranged at the discharge port, and an exhaust pipe is arranged at the bottom end surface of the cover plate.

[0005] As a preferred solution of the utility model, the cloth bag mounting bracket includes a mounting sleeve with an opening downward. The bottom end of the mounting sleeve is provided with a connecting angle connected to the cylinder wall of the cyclone cylinder. A plurality of mounting sleeve openings are arranged along the circumferential direction of the mounting sleeve.

[0006] As a preferred solution of the utility model, a fixing mechanism for fixing the cloth bag cylinder is arranged in the cyclone cylinder. The fixing mechanism includes an annular plate for abutting the bottom end of the cloth bag cylinder against the mounting sleeve. Vertical rods are arranged along the circumferential direction of the mounting sleeve at the annular plate. A connecting rod is arranged at the top end of the vertical rod, and a pressing rod for abutting against the connecting rod is arranged at the cover plate.

[0007] As a preferred solution of the utility model, an air inlet pipe communicating with the cyclone cylinder is arranged at the side wall of the upper end of the cyclone cylinder; a dust discharge port is arranged at the bottom end of the cyclone cylinder.

[0008] As a preferred solution of the utility model, the cover plate is bolted to the cyclone cylinder.

[0009] By adopting the above technical solutions, the beneficial effects that the utility model can achieve are as follows:

[0010] Compared with the currently common cyclone dust removal equipment, the utility model can further filter the dust with smaller mass remaining in the flue gas through the setting of the cloth bag cylinder, further improving the dust removal effect on the flue gas, and thus preferably avoiding the discharge of the dust with smaller mass in the flue gas into the air.

[0014] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0015] Embodiment 1

[0016] As Figures 1-3 shown, this embodiment provides a cyclone dust removal equipment for a hot blast stove, which includes a dust removal equipment body 100. The dust removal equipment body 100 includes a cyclone cylinder 110. An air inlet pipe 130 communicating with the cyclone cylinder 110 is provided at the side wall of the upper end of the cyclone cylinder 110; a dust discharge port 310 is provided at the bottom end of the cyclone cylinder 110. A cloth bag mounting bracket 210 is provided in the cyclone cylinder 110. A cloth bag cylinder 220 with an opening downward is sleeved on the cloth bag mounting bracket 210. An air discharge port 230 is provided at the top end of the cyclone cylinder 110. A cover plate 120 is provided at the air discharge port 230. The cover plate 120 is bolted to the cyclone cylinder 110. An air discharge pipe 240 is provided at the bottom end surface of the cover plate 120.

[0017] During use, the heat-exchanged flue gas is introduced into the cyclone cylinder 110 from the air inlet pipe 130 through a fan. After the flue gas enters the cyclone cylinder 110, the flue gas rotates in a spiral shape at high speed from top to bottom. During the rotation, the dust particles are thrown to the inner wall of the cyclone cylinder 110 under the action of a large centrifugal force and collide with the wall surface, gradually losing speed, and then fall along the wall of the cyclone cylinder 110 to the conical part under the action of gravity, and finally are discharged from the bottom dust discharge port 310. After the flue gas rotates to the bottom end of the cyclone cylinder 110, it starts to rise. During the rising process of the flue gas, it is filtered by the cloth bag cylinder 220 and discharged from the air discharge pipe 240.

[0018] Since the dust particles with relatively small mass in the flue gas may not be thrown to the inner wall of the cyclone 110, the cloth bag cylinder 220 can further filter the dust particles with relatively small mass remaining in the flue gas during the upward movement of the flue gas at the bottom end of the cyclone 110. Therefore, compared with the common cyclone dust removal equipment at present, the dust removal effect on the flue gas is further improved, and the dust particles with relatively small mass in the flue gas are preferably prevented from being discharged into the air.

[0019] In this embodiment, the cloth bag mounting bracket 210 includes a mounting sleeve 250 with an opening downward. A connecting angle 260 connected to the cylinder wall of the cyclone 110 is provided at the bottom end of the mounting sleeve 250. A plurality of mounting sleeve openings 270 are provided along the circumferential direction of the mounting sleeve 250.

[0020] Through the setting of the structure of the cloth bag mounting bracket 210, the cloth bag cylinder 220 can be installed at the mounting sleeve 250 and at the same time the cloth bag cylinder 220 can be supported, avoiding the deformation of the cloth bag cylinder 220 in the cyclone 110. Therefore, the stability of the cyclone dust removal equipment for the hot blast stove during use is preferably improved.

[0021] In order to further prevent the cloth bag cylinder 220 from displacing in the cyclone 110, a fixing mechanism for fixing the cloth bag cylinder 220 is provided in the cyclone 110. The fixing mechanism includes an annular plate 280 for abutting the bottom end of the cloth bag cylinder 220 against the mounting sleeve 250. Vertical rods 290 are provided along the circumferential direction of the mounting sleeve 250 at the annular plate 280. A connecting rod 2100 is provided at the top end of the vertical rod 290. A pressing rod 2110 for abutting against the connecting rod 2100 is provided at the cover plate 120.

[0022] Through the setting of the fixing mechanism, the bottom end of the cloth bag cylinder 220 can be tightly abutted against the bottom end of the mounting sleeve 250 by the annular plate 280, thereby further improving the stability of the cyclone dust removal equipment for the hot blast stove during use.

[0023] The working principle of the cyclone dust removal equipment for the hot blast stove in this embodiment is as follows:

[0024] During installation, first open the cover plate 120, then put the cloth bag cylinder 220 on the cloth bag installation bracket 210, then put the fixing mechanism on the outside of the cloth bag cylinder 220, and then install the cover plate 120. Fix the cloth bag cylinder 220 to the cloth bag installation bracket 210 through the cover plate 120, and then the filtering operation of the flue gas can be carried out. When filtering the flue gas, the flue gas enters the cyclone cylinder 110 from the inlet pipe 130. After the flue gas enters the cyclone cylinder 110, the flue gas rotates at a high speed in a spiral shape from top to bottom. During the rotation, the dust particles are thrown to the inner wall of the cyclone cylinder 110 under the action of a large centrifugal force and collide with the wall surface, gradually losing speed, and then fall along the wall of the cyclone cylinder 110 to the conical part under the action of gravity, and finally are discharged from the bottom ash discharge port 310. After the flue gas rotates to the bottom end of the cyclone cylinder 110, it starts to rise. During the rising process, the flue gas is filtered through the cloth bag cylinder 220 and discharged from the exhaust pipe 240. After the work is completed, the cover plate 120 can be opened and the fixing mechanism can be taken out to clean or replace the cloth bag cylinder 220.

[0025] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
