Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and more specifically, to a dust collector ash outlet storage device for automatic collection of dust emissions. Background Technology

[0002] In industrial production processes, dust collectors are widely used for the collection and treatment of secondary dust. The dust discharge port of the dust collector is a critical part for dust discharge, but in actual operation, dust can easily escape from the dust discharge port, leading to environmental pollution and resource waste.

[0003] In traditional offline pulse jet dust collectors, the lifting valve at the top of the dust collector is closed before the pulse jet is applied to cut off the flow of flue gas in the pulse jet chamber.

[0004] At this time, the pulse-jet cleaning chamber is in a prohibited state compared to other dust collector chambers. During this process, compressed air is instantly introduced into the filter bags through the air-bag pulse-jet cleaning device, creating an impact force that causes the dust on the surface of the filter bags to fall into the ash hopper under the action of the jet cleaning. It is then stored at the bottom of the ash hopper. At this time, traditional dust collection devices will have the following three problems:

[0005] 1. When the dust removal device is in operation, the area near the flue outlet is prone to dust collection due to the uneven suction of the induced draft fan, which can easily lead to poor dust removal effect inside the dust collector.

[0006] 2. After falling to the bottom of the ash hopper, if the flue valve at the ash hopper inlet is not closed, a passageway will be formed with other compartments. The main flue will still have suction, which will draw some of the dust that was falling into the ash hopper back into other compartments. This cycle repeats, preventing the ash from falling into the ash hopper effectively.

[0007] 3. When there is a lot of ash in the ash hopper, if the dust needs to be conveyed out of the system, it is usually necessary to use a rotary feeder for unloading; if a traditional ton bag is used for receiving the material, the unloading process will cause dust to be generated, which will lead to further environmental pollution.

[0008] Traditional dust collectors, in terms of offline pulse jet cleaning / ash unloading / dust collection, cannot detect whether ash is falling into the ash hopper. This requires manual intervention to be present at the system's perimeter throughout the entire operation process, increasing labor costs and making the operation cumbersome.

[0009] Most existing ash discharge storage devices suffer from poor sealing and ineffective dust control, creating an urgent need for a device that can automatically collect and disperse dust. Utility Model Content

[0010] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dust collector bottom ash outlet storage device for automatic collection of dust dispersion, so as to solve the problems that most bottom ash outlet storage devices in the prior art have poor sealing performance and poor dust control effect.

[0011] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust collector ash outlet storage device for automatic collection of emitted dust, comprising...

[0012] The dust collection chamber includes an offline lifting valve, a dust hopper, a bag filter air manifold jet cleaning mechanism, a partition inclined plate, and a flue gas inlet pipe. The offline lifting valve is installed inside the top of the dust collection chamber. The dust hopper is fixedly installed at the bottom of the dust collection chamber. The bag filter air manifold jet cleaning mechanism is installed above the dust hopper. The flue gas inlet pipe is installed on the side of the dust collection chamber. The top of the flue gas inlet pipe is connected to the dust collection chamber and is equipped with a partition inclined plate. The bottom end of the flue gas inlet pipe is connected to the dust hopper inlet. The side of the dust hopper inlet is equipped with a dust anti-backflow mechanism. Multiple evenly distributed guide plates are fixedly installed in the inner cavity of the top of the dust hopper.

[0013] The bottom of the ash hopper is provided with an ash receiving and sealing box, and a dust collection pipe is installed on the upper surface of the ash receiving and sealing box. The top of the dust collection pipe is sleeved and installed on the lower surface of the ash hopper opening and is connected to the ash hopper opening.

[0014] The inner surface of the bottom side of the ash silo pipe opening is fixedly installed with multiple thin steel strips, and the upper edge of the ash silo pipe opening is fixedly installed with a perforated steel plate at a 15° downward angle.

[0015] The dust anti-reverse mechanism includes a shaft, the two ends of which are fixedly installed to the inner wall of the ash hopper. A filter cloth is hinged to the outer surface of the shaft, and a round steel bar is fixedly installed at the bottom of the filter cloth.

[0016] It also includes an automatic control module, which includes the logic control of sensors, controllers, and actuators.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In the above scheme, the device can achieve efficient dust collection during the operation of the dust removal system: when the flue gas passes through the uniformly distributed guide plate in the ash hopper chamber, the array of fine steel bars set in the ash hopper pipe ensures that the dust is evenly distributed. At the same time, the dust anti-reverse mechanism effectively improves the dust removal efficiency by colliding and falling the heavy dust into the ash hopper.

[0019] In the above scheme, when the compartment is offline: the bag filter air manifold jet cleaning mechanism is activated, and the dust accumulated on the surface of the filter bag falls off instantly under the pulse action. At this time, the negative pressure suction of the main flue of the dust removal system causes the dust anti-backflow mechanism to tightly adhere to the surface of the thin steel strip to form a sealed state, ensuring that all the fallen dust is retained in the ash hopper, and completely avoiding the phenomenon of dust backflow to other compartments due to negative pressure backflow.

[0020] In the above scheme, when the ash hopper is full and unloading ash, an ash-receiving sealing box is installed below the unloader. By connecting the dust removal flue negative pressure system to the sealing box, the negative pressure environment of the existing dust removal device is cleverly utilized to achieve dust collection during the ash unloading process, ensuring clean operation of the material transfer process.

[0028] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0029] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a dust collector lower ash inlet storage device for automatic collection of dust emissions, including...

[0030] The dust removal chamber 1, offline lifting valve 2, ash hopper 3, bag filter air manifold jet cleaning mechanism 4, partition inclined plate 5, and flue gas inlet pipe 6 are provided. The offline lifting valve 2 is installed inside the top of the dust removal chamber 1. The ash hopper 3 is fixedly installed at the bottom of the dust removal chamber 1. The bag filter air manifold jet cleaning mechanism 4 is installed above the ash hopper 3. The flue gas inlet pipe 6 is installed on the side of the dust removal chamber 1. The top of the flue gas inlet pipe 6 is connected to the dust removal chamber 1 and is equipped with partition inclined plate 5. The bottom end of the flue gas inlet pipe 6 is connected to the ash hopper pipe port 7. The side of the ash hopper pipe port 7 is equipped with dust anti-backflow mechanism 8. Multiple evenly distributed guide plates 11 are fixedly installed in the inner cavity of the top of the ash hopper 3.

[0031] By setting up a uniformly distributed guide plate 11, the principle of the nearest passage under the action of flue gas suction is utilized; the uniformly distributed guide plate 11 is set at the flue outlet so that the flue gas passes through the uniformly distributed guide plate 11 and is rectified; thus, the dust collector filter bag can be uniformly dusted in all places.

[0032] Among them, the bottom end of the ash hopper 3 is provided with an ash receiving and sealing box 10, and the upper surface of the ash receiving and sealing box 10 is equipped with a dust collection pipe 9. The top end of the dust collection pipe 9 is sleeved and installed with the lower surface of the ash hopper pipe opening 7, and is connected to the ash hopper pipe opening 7.

[0033] By setting up structures such as dust collection pipe 9 and dust receiving sealing box 10, when the storage inside the dust hopper 3 reaches the upper limit, the unloading mechanism below the dust hopper 3 needs to be activated. This mechanism is located at the interface between the dust hopper 3 and the dust receiving sealing box 10 to collect the material into a ton bag. During the unloading process, the ton bag needs to be fixed and supported while the unloading area is sealed, and it also has the function of automatic dust collection. The specific operation is as follows:

[0034] (1) Ash receiving sealing box 10: The ash receiving sealing box 10 is placed in the area below the ash discharge valve of the ash hopper. Its size is determined according to the ton bag frame. During the ash discharge process, it can facilitate the ash discharge and fall smoothly into the ton bag, while sealing off the dust in the ash discharge area to prevent the ash dust from spreading.

[0035] (2) Dust collection pipe 9: This pipe connects to the inlet area of ​​the ash hopper pipe 7 in one direction and to the top of the ash receiving sealing box 10 in the other direction. During the ash unloading process of the ash hopper, the dust in the ash receiving sealing box 10 is effectively collected by the suction force of the dust collector flue inlet through this collection pipe. An electric control valve is added in the middle of the pipe to open and close as needed to prevent the collection pipe from being constantly open and wasting the negative pressure effect of the dust collector.

[0036] (3) Automatic control module 12: The automatic control module 12 includes sensors, a controller, and an actuator. ① The sensors detect the ash discharge status of the material in the storage bin; the controller opens the electric valve in the dust collection pipe 9 according to the sensor signal, thus achieving effective material collection; ② Conversely, when the sensors do not detect ash discharge, the controller closes the electric valve according to the sensor feedback; ③ At the same time, when no ash discharge is detected, the controller controls the ash hopper auxiliary ash discharge device to operate.

[0037] Among them, multiple thin steel strips 70 are fixedly installed on the inner surface of the bottom side of the ash silo pipe opening 7, and a perforated steel plate 71 is fixedly installed on the upper edge of the ash silo pipe opening 7, and is horizontally downward at 15°.

[0038] The dust anti-reverse mechanism 8 includes a shaft 80, the two ends of which are fixedly installed on the inner wall of the ash hopper 3. A filter cloth 81 is hinged to the outer surface of the shaft 80, and a round steel bar 82 is fixedly installed at the bottom of the filter cloth 81.

[0039] By setting up a dust backflow prevention mechanism 8, which consists of a common shaft 80, filter cloth 81, and round steel 82, a dust backflow prevention mechanism 8 is added at the ash hopper inlet 7 to prevent dust from falling into other compartments under the suction of the main inlet flue when the dust collector is offline and cleaning is in progress. When the dust collector compartment is in operation, this mechanism opens under the suction of the induced draft fan. Utilizing the air permeability of the filter cloth 81 and its fixation with the round steel 82, the backflow prevention mechanism forms a passage for dust removal under negative pressure through the action of the shaft 80. When the offline valve is closed, the suction at the top of the compartment disappears, and the mechanism, relying on the suction of the main flue inlet, engages with the inlet of the ash hopper inlet 7 to prevent dust leakage.

[0040] It also includes an automatic control module 12, which includes the logic control of sensors, controllers and actuators.

[0041] The working process of this utility model is as follows:

[0042] This device is suitable for offline pulse bag dust collectors with multiple compartments. The device is placed in the ash hopper of each dust collection compartment. When the dust collection system is running, it can effectively collect dust. At the same time, when the flue gas passes through the uniformly distributed guide plate 12 inside the ash hopper 3 compartment, the multiple thin steel bars 70 set inside the ash hopper pipe 7 play the role of uniformly distributing dust. The dust anti-reverse mechanism 8 plays the role of heavy dust collision falling into the ash hopper, thereby increasing the dust collection efficiency.

[0043] When the corresponding compartment is offline: the bag filter air bag blowing mechanism 4 is turned on, and the dust adsorbed on the surface of the filter bag will fall off instantly. At this time, the dust anti-backflow mechanism 8 is closed due to the suction force of the main flue. The dust will be completely retained inside the ash hopper, avoiding the situation where the ash falls into other compartments through the flue due to negative pressure back suction.

[0044] When the ash hopper is full, the ash needs to be unloaded using a discharger for material storage. At this time, an ash receiving and sealing box 10 is installed below the discharger. The dust is collected through a pipe to the ash receiving and sealing box 10 by utilizing the negative pressure of the dust removal flue. This allows the existing dust removal device to be used to collect dust.

[0045] Through automated control, the dust collector has achieved automation in the processes of pulse jet cleaning, ash unloading, and dust collection, greatly reducing manual operation costs.

[0046] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
