Description

Technical Field

[0001] The present invention relates to the technical field of bag dust collectors, in particular to a bag dust collector for furnace power plants. Background Art

[0002] Boiler power refers to equipment or systems related to boilers and electricity. These equipment or systems will remove flue gas containing a large amount of impurities. The flue gas has a low water content and needs to be dusted before discharge. The dust removal equipment commonly used in boiler power is mainly bag dust collector, also known as bag dust collector or filter dust collector. It is a dry and efficient dust removal equipment widely used in various industrial fields. The bag dust collector uses a fan to inhale flue gas. The flue gas passes through a baffle to filter out large particles of impurities, and then enters from the outside of multiple groups of filter bags for filtration. For example, Chinese invention patent with authorization announcement number CN102784526B discloses a bag dust collector, including: a box with a purified gas outlet; multiple dust removal bags arranged in the box; an ash hopper arranged at the bottom of the box, which has a dust-laden gas inlet; and a partition arranged in the box to divide the box space into at least two isolated dust removal zones, each of which is connected to the ash hopper through an on-off valve. However, current bag dust collectors have the following defects when used in the boiler power field:

[0003] Long-term dust removal work will cause impurities to accumulate on the outside of the filter bag, resulting in increased air intake resistance. In particular, the flue gas of the furnace power system has more impurities, which requires the filter bag to be cleaned. At present, the main method of cleaning is blowing. Although the blowing method is used, the impurities are not blown off. Instead, air several times the amount of jet air is used to enter the filter bag to form air waves. This air wave causes the filter bag to expand, deform and vibrate rapidly, thereby shaking off the dust on the filter bag. In fact, it is the shaking of the filter bag during expansion and contraction that shakes off the dust. When used in the furnace power system, the cleaning frequency is high, and the filter bag often expands and deforms, which greatly reduces the life of the filter bag and is not conducive to use.

[0004] For this reason, we propose a bag dust collector for furnace power to solve the above problems. Summary of the Invention

[0048] Example 3:

[0049] See also Figure 1-12 , which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is used, the exhaust duct 24 is connected to the exhaust equipment, and the flue gas is introduced by a fan. The flue gas enters from the air inlet pipe 35, passes through the conical baffle 310 to block most of the large particles of impurities, enters the silo 21, enters from the outside of the filter bag 28, and is then discharged from the exhaust duct 24. When the gas resistance in the silo 21 reaches a threshold, the dust removal is turned off. At this time, the valve 2618 is opened, and air is blown into the backflush assembly 25 through the blowing sub-pipe 263. At the same time, the second servo reduction motor 2615 is started to drive the backflush assembly 25 to rotate, and then the filter bag 28 is backflushed and cleaned through the nozzle 252. After completion, the dust removal work continues; The air inlet channel 33 in the dust collection component 3 of the present invention is small at the top and large at the bottom. In this way, when the smoke enters, it will be better blocked by the conical baffle 310, and more large particle impurities will be filtered out, avoiding more particle impurities from adhering to the surface of the filter bag 28. Compared with the traditional baffle, the effect is better. When the dust is sprayed during cleaning, the present invention not only sprays at the top, but also sprays through multiple nozzles 252. At the same time, the high-speed joint 264 rotates slowly, and multiple nozzles 252 are used for spraying to achieve backblowing cleaning. In this way, all positions of the filter bag 28 will be backblown, and there is no need to expand the filter bag 28. Only backblowing can be used to blow off the surface impurities. In this way, the filter bag 28 will not be deformed during cleaning, thereby extending the service life of the filter bag 28.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
