Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching system equipment, in particular to a novel dry coke quenching water seal cover. Background Art

[0002] The CDQ system is a key production unit in a coking plant, consisting of multiple pieces of equipment and process flows, and boasts a high degree of automation. The loading device is used to load red coke into the CDQ furnace. When loading red coke, the loading device's mobile trolley is pre-positioned to the CDQ furnace entrance, positioning the mobile hopper just below the fixed hopper and dust hood. The sliding water seal surrounding the mobile hopper, guided by guide rails on both sides of the track, falls into the water seal groove. Fireproof cloth is used on the sliding water seal and hopper.

[0003] The function of the sealing device here is to prevent dust from rushing upward after the red coke is loaded. If not blocked, the dust will seriously pollute the environment and bring a lot of inconvenience to on-site operations. In the existing technology, high-temperature sealing cloth and water tank are used in combination to achieve the technical effect of sealing.

[0004] However, in the current CDQ system, there is a gap between the sliding water seal cover and the moving hopper. Although coke powder will not escape from the water seal tank into the atmosphere during the coke loading process, it will fall into the water seal tank. In addition, the existing technology and measures are limited, and the coke powder in the water seal tank is difficult to clean, and manual cleaning is often required under high temperatures and dangers. If it is not cleaned in time or the effect is not ideal, coke powder will accumulate in the water seal tank, and the tank wall will be baked by high temperature. The heat cannot be taken away in time, causing leakage in the water seal tank and water leakage into the CDQ furnace, which has a great impact on the safe and normal operation of the CDQ system. After the leakage occurs, coke loading needs to be stopped and maintenance needs to be arranged, which increases labor costs and equipment expenses. Utility Model Content

[0005] The utility model aims to provide a new type of CDQ water seal cover, which adds a cover plate to the skirt of the existing CDQ sliding seal cover. When loading coke, the lower cover plate can well cover the water seal groove to prevent coke powder and coke blocks from falling into the water seal groove.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A new type of dry quenching water seal cover includes a movable hopper, a sliding water seal cover and a water seal groove. A fireproof cloth is connected between the upper end of the sliding water seal cover and the outer side of the movable hopper. The sliding water seal cover moves up and down outside the movable hopper. Lower cover plates are also connected to the inner and outer sides of the sliding water seal cover. The sliding water seal cover is inserted downward into the water seal groove, and the lower cover plates on both sides are respectively covered on the inner and outer sides of the top of the water seal groove.

[0008] By adopting the above technical solution, a lower cover plate is added to the skirt of the existing dry coke quenching sliding sealing cover. When loading coke, the lower cover plate can well cover the water seal groove. The inner lower cover plate can prevent coke powder from falling into the water seal groove, and the outer lower cover plate can prevent coke blocks from falling into the water seal groove when loading coke. Even if they fall onto the lower cover plate, the coke powder and coke can be cleaned in a non-high temperature area away from the furnace mouth after the loading device trolley is moved away, which facilitates cleaning and improves the working environment of workers.

[0009] Furthermore, an upper cover plate is connected to the inner side of the sliding water seal cover, the upper cover plate is arranged on the outer side of the movable hopper, and the lower cover plate is located below the fireproof cloth.

[0010] By adopting the above technical solution, the upper cover plate can be sealed with the lower edge of the movable hopper when loading coke, reducing the smoke from entering under the fireproof cloth, extending the service life of the fireproof cloth, and also playing the role of double-layer sealing.

[0011] Furthermore, the inner edge of the lower cover plate is also provided with a high-temperature resistant flexible sealing edge.

[0012] By adopting the above technical solution, coke powder is mainly produced at the inner furnace mouth and is sealed in the water seal groove through the high-temperature resistant flexible sealing edge, further preventing the coke powder from falling into the water seal groove and improving the sealing performance.

[0013] Furthermore, the high temperature resistant flexible sealing edge is detachably connected to the edge of the lower cover plate.

[0014] By adopting the above technical solution, the disassembly and replacement of the high-temperature resistant flexible sealing edge can be facilitated, and the sealing performance can be guaranteed.

[0015] Furthermore, the high temperature resistant flexible sealing edge includes a ceramic fiber rope arranged along the length direction of the lower cover plate.

[0016] By adopting the above technical solution, the ceramic fiber rope is used to improve the high temperature resistance of the sealing structure between the water seal groove and the water seal groove, and the stability of its sealing function is improved.

[0017] Furthermore, the high temperature resistant flexible sealing edge abuts against the upper edge of the water seal groove.

[0018] By adopting the above technical solution, the high-temperature resistant flexible sealing edge can be pressed against the upper edge of the water seal groove through its elasticity, thereby improving its sealing performance and preventing coke powder from falling into the water seal groove.

[0019] Furthermore, the edge of the upper cover plate is provided with a high-temperature resistant flexible sealing edge.

[0020] By adopting the above technical solution, the fireproof cloth is sealed under the fireproof cloth, which reduces the smoke from entering under the fireproof cloth, prolongs the service life of the fireproof cloth, and also plays the role of double sealing.

[0021] Furthermore, one side of the edge of the inner and outer lower cover plates is tilted downward, forming an umbrella shape.

[0022] By adopting the above technical solution, when a large amount of coke powder or coke blocks accumulates on the lower cover plate, the coke powder or coke blocks can automatically slide into or outside the furnace.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. This application adds a double-layer cover plate to the skirt of the existing CDQ sliding sealing cover, with high-temperature resistant flexible sealing material fixed to the edge of the cover plate. When loading coke, the lower cover plate can effectively cover the water seal groove to prevent coke powder on the inside and coke blocks on the outside from falling into the water seal groove. Even if coke powder and coke fall onto the lower cover plate, they can be cleaned in a non-high-temperature area away from the furnace mouth after the loading device trolley is removed, which facilitates cleaning and improves the working environment for workers.

[0025] 2. The upper cover plate provided in this application can be sealed with the lower edge of the movable hopper when loading coke, thereby reducing the entry of smoke under the fireproof cloth, extending the service life of the fireproof cloth, and also playing the role of double-layer sealing.

[0026] 3. The lower cover is designed in an umbrella-like structure, so that when coke powder or coke lumps accumulate on the lower cover, they can automatically slide into or outside the furnace, making it easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS
