A dust collector capable of reducing flue gas velocity

Abstract

This utility model discloses a dust collector capable of reducing flue gas velocity. It includes a flue gas inlet located in the settling chamber at the bottom of the dust collector body. Inside the settling chamber, several upper and lower baffles are arranged in a staggered manner above the flue gas inlet. A flue gas rising channel is provided between the upper and lower baffles. By installing staggered lower and upper baffles inside the settling chamber of the dust collector, this utility model can not only block and intercept coarse dust particles in the flue gas from falling down without affecting the flue gas flow rate, but also reduce the flue gas velocity. This allows more particles to be collected in the settling chamber, avoiding high-speed impact on the dust collector bags and greatly extending the service life of the dust collector bags.

Description

Technical Field

[0001] This utility model relates to the field of dust collectors, specifically to a dust collector capable of reducing flue gas velocity. Background Technology

[0002] In the baghouse dust collector of the cleanroom, high-temperature flue gas typically enters the settling chamber from the lower flue gas inlet and flows upwards (e.g., Figure 5 As shown, dust is filtered through multiple enclosed dust collector bags installed at the top. The purified flue gas exits from the top outlet, while the filtered dust falls and accumulates in the lower settling chamber. However, the flue gas entering the settling chamber from the inlet travels at a relatively high velocity and contains a significant amount of dust. This dust exerts a severe impact on the upper dust collector bags, leading to accelerated wear and tear and a reduced lifespan. Therefore, the existing technology urgently needs improvement to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a dust collector capable of reducing flue gas velocity.

[0004] This utility model is achieved through the following technical solution:

[0005] A dust collector capable of reducing flue gas velocity includes a flue gas inlet located in the settling chamber at the bottom of the dust collector body. Inside the settling chamber, there are several upper and lower baffles arranged in a staggered manner above the flue gas inlet, and an upward channel for flue gas is provided between the upper and lower baffles.

[0006] Alternatively, the upper and lower spoilers include support partitions that are staggered vertically, and umbrella-shaped baffles are installed at the upper and lower ends of the support partitions of the upper and lower spoilers, respectively.

[0007] Alternatively, the width of the umbrella-shaped baffle is the same as the width of the ascending channel.

[0008] Alternatively, several air vents can be opened on both sides of the umbrella-shaped baffle.

[0009] Alternatively, the axis of the blow-out hole is set perpendicular to the side of the umbrella-shaped baffle.

[0010] Alternatively, the blow-off holes may be tapered.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: By installing staggered lower and upper baffles inside the settling chamber of the dust collector, this utility model can not only block and intercept coarse dust particles in the flue gas from falling down without affecting the flue gas flow rate, but also reduce the flue gas velocity, so that more particles can be collected in the settling chamber, avoiding high-speed impact on the dust collector bags and greatly extending the service life of the dust collector bags.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 As shown, a dust collector capable of reducing flue gas velocity includes a flue gas inlet 3 located in the lower settling chamber 2 of the dust collector body 1. Inside the settling chamber 2, there are several upper and lower baffles 6 and lower baffles 5 arranged in a staggered manner above the flue gas inlet 3. A flue gas rising channel 7 is provided between the upper baffles 6 and the lower baffles 5.

[0020] By employing staggered upper and lower baffles, the upward velocity of the flue gas is slowed down after it enters the settling chamber, increasing its residence time and improving dust removal efficiency. The upward channel between the upper and lower baffles ensures the flue gas can continue to rise smoothly after deceleration, preventing blockage. This design effectively solves the problem of reduced dust collector efficiency caused by excessively high flue gas velocity. Compared to existing technologies, this solution significantly improves dust collector performance, reduces wear on filter bags, and extends their service life through simple structural improvements, demonstrating high practicality and economic efficiency.

[0021] like Figure 2 As shown, the upper spoiler 6 and the lower spoiler 5 include support partitions 8 that are staggered vertically. Umbrella-shaped baffles 9 are installed at the upper and lower ends of the support partitions 8 of the upper spoiler 6 and the lower spoiler 5, respectively. The staggered vertical arrangement of the support partitions causes the flue gas to be blocked and dispersed by the umbrella-shaped baffles when passing through the rising channel, thereby effectively reducing the speed of the flue gas.

[0022] like Figure 2 As shown, the width of the umbrella-shaped baffle 9 is the same as the width of the rising channel 7. This design ensures that the flue gas is evenly distributed when passing through the rising channel, reducing localized impact on the upper dust collector bags. This design also results in smoother flue gas flow, reducing wear on the dust collector bags and extending their service life.

[0023] In a preferred embodiment, the width of the umbrella-shaped baffle can be adjusted by changing the installation position of the supporting partition, so that the edge of the umbrella-shaped baffle is aligned with the inner wall of the rising channel. Furthermore, the width of the umbrella-shaped baffle can also be adjusted by changing its shape and size to accommodate rising channels of different widths. For example, the umbrella-shaped baffle can adopt an arc-shaped design to better guide the flow of flue gas.

[0024] like Figure 3 , 4 As shown, several blowing holes 10 are opened on both sides of the umbrella-shaped baffle 9. The setting of the blowing holes allows the flue gas to be distributed more evenly when passing through the umbrella-shaped baffle, reducing the direct impact of local high-speed airflow on the dust collector bag. At the same time, the flue gas moving upward from the blowing holes 10 can prevent particulate dust from accumulating on the umbrella-shaped baffle 9.

[0025] like Figure 4 As shown, the axis of the blow-out hole 10 is perpendicular to the side of the umbrella-shaped baffle 9. This design allows the blow-out hole to more effectively guide the flow of flue gas, ensuring that the flue gas is evenly dispersed when passing through the umbrella-shaped baffle. This arrangement allows the blow-out hole to better control the flow direction and speed of the flue gas, thereby reducing the impact of the flue gas on the dust collector bag and extending the service life of the filter bag.

[0026] like Figure 4 As shown, the dispersing orifice 10 adopts a conical design. This conical design causes the flue gas velocity to gradually decrease as it passes through the orifice, resulting in more uniform gas dispersion. This dispersion effect helps reduce the overall velocity of the flue gas in the rising channel, minimizing direct impact on the upper dust collector bags and thus extending their service life. The conical orifice design not only improves the flue gas dispersion efficiency but also helps reduce dust accumulation around the dispersing orifice, further optimizing the dust removal effect.

[0027] The implementation principle of a dust collector capable of reducing flue gas velocity according to an embodiment of this application is as follows:

[0028] High-temperature flue gas enters the settling chamber 2 through the flue gas inlet 3 and passes through the rising channel 7 between the lower baffle 5 and the upper baffle 6. When passing through the rising channel 7, it is blocked by the umbrella-shaped baffles 10 that are staggered vertically. Without affecting the flue gas flow rate, it can not only block and intercept coarse dust particles in the flue gas to fall, but also reduce the flue gas velocity, so that more particles can be collected in the settling chamber, avoiding high-speed impact on the dust collector bag 4 and greatly extending the service life of the dust collector bag 4.
