Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry quenching technology, specifically to a dry quenching dust removal device. Background Technology
[0002] The coke produced by dry quenching is over 200 degrees Celsius and is a mixture of coke lumps and coke powder. The dust generated by dry quenching has a diameter of five to fifty micrometers. During the conveyor belt process, due to the temperature of the coke itself and the bumps of the belt, a large amount of dust is generated. Large dust particles fall to the ground relatively quickly, and in severe cases, they can even affect the operation of the belt. Small particles are suspended in the air, causing reduced visibility and a harsh working environment. This situation exists from the time the coke comes out of the dry quenching coke until it reaches the coke transfer shed. Utility Model Content
[0003] Therefore, this utility model provides a dry quenching coke dust removal device to solve the problems existing in the above-mentioned technology.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A dry quenching coke dust removal device, characterized in that it comprises:
[0006] A cleaning chute is installed at the coke outlet of the dry quenching coke, and the cleaning chute is inclined and gradually decreases in height from the coke outlet side. The bottom of the cleaning chute has a hollow structure, and the lower end of the cleaning chute is located above the conveyor belt.
[0007] The air duct is located at the bottom of the cleaning chute and completely encloses the hollow structure at the bottom of the cleaning chute. An air inlet is provided on one side of the air duct for connecting to a compressed air source.
[0008] A dust collection hood is installed on top of the cleaning chute and completely covers the top of the cleaning chute. The dust collection hood is connected to a collection device through a conveying pipe.
[0009] Optionally, the cleaning chute is a U-shaped trough structure, with both ends of the U-shaped trough serving as baffles, and several air holes formed at the bottom of the U-shaped trough to create a hollow structure.
[0010] Optionally, the air duct is a sealed shell structure with an opening at the top, and the top opening of the air duct is fixed to the bottom of the cleaning chute to seal the air holes at the bottom of the cleaning chute.
[0011] Optionally, the angle between the cleaning chute and the horizontal plane is 30°.
[0012] Optionally, the bottom opening of the dust collection hood is fixedly connected to the top of the inclined chute and is sealed to the top opening of the inclined chute, and the top of the dust collection hood is connected to the dust removal station.
[0013] This utility model has at least the following beneficial effects:
[0014] This invention places an inclined cleaning chute at the coke outlet, allowing the coke to roll downwards along the chute. During this downward rolling process, compressed air is blown into the air duct at the bottom of the cleaning chute, blowing off the dust adhering to the outside of the coke blocks. The dust is then collected by the dust collector at the top, ensuring that the coke falling onto the conveyor belt has less or no dust adhering to it. This prevents dust from being generated during the conveyor belt transport process, improving the quality of the working environment and visibility. Attached Figure Description

[0024] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or devices, or steps or units added based on further optimizations of the inventive concept.
[0025] like Figures 1-3 As shown, this utility model discloses a dry quenching coke dust removal device, comprising:
[0026] A cleaning chute 1 is installed at the coke outlet of the dry quenching coke, and the cleaning chute 1 is inclined and gradually decreases in height from the coke outlet side. The bottom of the cleaning chute 1 has a hollow structure, and the lower end of the cleaning chute is located above the conveyor belt 2.
[0027] Air duct 3 is located at the bottom of the cleaning chute 1 and completely covers the hollow structure at the bottom of the cleaning chute 1. An air inlet 4 is provided on one side of the air duct 3 for connecting to a compressed air source.
[0028] Dust collection hood 5 is installed on top of the cleaning chute 1 and completely covers the top of the cleaning chute 1. The dust collection hood 5 is connected to the collection device through the conveying pipe 6.
[0029] The aforementioned cleaning chute 1 can be fixed at the coke outlet, and the cleaning chute 1 is set at an inclination, with the end connected to the coke outlet being higher and the end away from the coke outlet being lower, forming a slope structure. The slope is generally 30°, but can also be adjusted according to actual needs (coke size, etc.). After the coke comes out of the coke outlet, it rolls down along the inclined cleaning chute 1. High-pressure air is used to blow away the dust adhering to the coke surface. The end of the cleaning chute 1 away from the coke outlet is fixed above the conveyor belt 2, and the coke after dust removal falls onto the conveyor belt 2 to complete the conveying.
[0030] The coke outlet and conveyor belt 2 mentioned above can both be equipped with existing devices. The cleaning chute 1 can be fixed between the two to complete the dust removal.
[0031] The bottom of the above-mentioned cleaning chute 1 has a hollow structure. The size of the air hole 7 in the hollow structure should be 3-4mm to serve as a ventilation hole 7, while avoiding blocky coke from clogging the air hole 7.
[0032] The bottom of the cleaning chute 1 is connected to the air duct 3. The air duct 3 completely covers the air hole 7 at the bottom of the cleaning chute 1, forming a sealed structure. The bottom of the cleaning chute 1 has an air inlet 4 connected to a compressed air source. Compressed air is introduced into the air duct 3 and blown into the cleaning chute 1 along the air hole 7. As the coke rolls along the cleaning chute 1, the dust attached to the coke is blown off, thereby ensuring that the dust attached to the coke can be completely cleaned.
[0033] A dust collector hood is installed on top of the cleaning chute 1. The dust collector hood covers the top of the cleaning chute 1 and is connected to the dust collection station through the conveying pipe 6. Compressed air blows the dust upwards, and the dust collection station's suction pump collects the blown dust.
[0034] The cleaning chute 1 has a U-shaped trough structure, with baffles at both ends and several air holes 7 formed at the bottom of the U-shaped trough to create a hollow structure.
[0035] The aforementioned cleaning chute 1 is designed with a U-shaped structure, and the baffles formed on both sides can ensure sealing and material discharge.
[0036] The air duct 3 is a sealed shell structure with an opening at the top. The opening at the top of the air duct 3 is fixed to the bottom of the cleaning chute 1 to seal the air hole 7 at the bottom of the cleaning chute 1.
[0037] The aforementioned air duct 3 can also be a double-layered U-shaped cleaning chute 1 with air holes 7 in the upper layer and a sealed lower layer forming the air duct 3.
[0038] The bottom opening of the dust collection hood 5 is fixedly connected to the top of the inclined chute and is sealed to the top opening of the inclined chute. The top of the dust collection hood 5 is connected to the dust removal station.
[0039] The dust collector hood described above is shaped like a funnel, which facilitates the flow of dust and allows for faster dust collection.
[0040] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0041] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
[0042] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
