Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching, in particular to a dust recovery device for dry coke quenching. Background Art

[0002] Dry quenching is a coke quenching method that uses inert gas to extinguish red-hot coke. Dry quenching can recycle the sensible heat of red coke, improve the quality of coke, and reduce the pollution of the quenching operation to the environment. The dust generated during dry quenching needs to be recovered by a dust recovery device. The existing recovery device humidifies and collects the dust by spraying water through a nozzle. The nozzle sprays a large amount of water, and the dust humidity is too high when the dust is humidified and recovered, which is not conducive to the recovery of dust. Utility Model Content

[0003] The utility model aims to solve the shortcomings of the prior art that the water spraying amount of the nozzle is large and the dust humidity is too high when the dust is humidified and recovered, and proposes a dust recovery device for dry coke quenching.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A dust recovery device for dry coke quenching is designed, including a box body, wherein:

[0006] A partition is fixedly connected to the box body, and the partition divides the box body into a first chamber and a second chamber. A motor is fixedly connected to the upper end of the box body, and the output end of the motor extends into the second chamber. An open cylinder is fixedly connected to the output end of the motor, and the bottom end of the open cylinder passes through the partition and extends into the first chamber. A through hole is provided at the upper end of the side wall of the open cylinder, and a dust recovery pad is connected to the inner wall of the open cylinder. A humidification mechanism for humidifying the dust recovery pad is connected to the box body.

[0007] Preferably, the box body and the partition are an integral structure.

[0008] Preferably, the dust recovery pad is a dust-removing wool pad.

[0009] Preferably, the humidification mechanism includes an incomplete hollow ring, which is fixedly connected to the open cylinder, and a plurality of conduits are connected on the inner wall of the incomplete hollow ring at equal intervals along the axial direction, and the bottom end of each of the conduits is connected to a drip irrigation head, which is inserted into the upper end of the dust recovery pad.

[0010] Preferably, the conduit is a high temperature resistant plastic tube.

[0011] Preferably, the gap of the incomplete hollow ring is connected to the through hole.

[0012] The utility model proposes a dust recovery device for dry coke quenching, which has the following beneficial effects:

[0013] After the motor is powered on, it drives the open cylinder to rotate, and the open cylinder drives the dust recovery pad to rotate. The humidification mechanism supplies water to humidify the dust recovery pad, so that the dust recovery pad remains in a moist state. The dust gas entering the open cylinder contacts the rotating dust recovery pad, and the dust in the gas contacts the moist dust recovery pad, thereby humidifying the dust in the gas and preventing the dust humidity from being too high.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1

[0021] Reference Figure 1-3 , a dust recovery device for dry coke quenching, comprising a box 1, wherein:

[0022] A partition 2 is fixedly connected to the box body 1, and the box body 1 and the partition 2 are an integral structure. The partition 2 divides the box body 1 into a first chamber and a second chamber. The first chamber is connected to an air inlet pipe, and a sealing plate is detachably connected to the first chamber. The second chamber is connected to an air outlet pipe. A motor 3 is fixedly connected to the upper end of the box body 1, and the output end of the motor 3 extends into the second chamber. An open cylinder 4 is fixedly connected to the output end of the motor 3, and the bottom end of the open cylinder 4 passes through the partition 2 and extends into the first chamber. A through hole 5 is opened at the upper end of the side wall of the open cylinder 4, and a dust recovery pad 6 is connected to the inner wall of the open cylinder 4. The dust recovery pad 6 is a dust-removing wool cloth pad. A humidifying mechanism 7 for humidifying the dust recovery pad 6 is connected to the box body 1.

[0023] Working process: when the dust is being recovered, the motor 3 is powered on and started, and after the motor 3 is powered on and started, it drives the open cylinder 4 to rotate, and the open cylinder 4 drives the dust recovery pad 6 to rotate, and the humidification mechanism 7 delivers water to humidify the dust recovery pad 6, so that the dust recovery pad 6 remains in a moist state;

[0024] The dust gas enters the first chamber through the air inlet pipe, and the dust gas in the first chamber enters the open cylinder 4. The dust gas entering the open cylinder 4 contacts with the rotating dust recovery pad 6, and the dust in the gas contacts with the wet dust recovery pad 6 to humidify the dust in the gas. After humidification, the dust adheres to the dust recovery pad 6. As the dust on the dust recovery pad 6 gradually increases, the dust on the dust recovery pad 6 falls into the first strong chamber when the dust recovery pad 6 rotates, and the dust in the gas is recovered. The dust in the gas is humidified and recovered by the wet dust recovery pad 6, which will not cause the humidity of the dust to be too high. The treated gas passes through the through hole 5 and the outlet pipe in turn and is released from the outlet pipe.
