Description

Technical Field

[0001] The invention belongs to the technical field of coke quenching, and in particular relates to a dry-wet combined coke quenching device and process. Background Art

[0002] Coke quenching technology, as a key link in the coking production process, has the main goal of cooling the hot coke out of the furnace to room temperature. At present, the industry mainly uses two methods: wet quenching and dry quenching.

[0003] Wet quenching technology is applicable to a wide range of coking enterprises. Its principle is to cool down the high-temperature red coke by directly sprinkling water on it. In specific operations, the quenching car transports the red coke to the quenching tower. There are several groups of spray heads on the top of the tower. Water mist is sprayed on the red coke to generate a large amount of steam. These steam escape from the top of the quenching tower to complete the cooling process. In contrast, dry quenching technology is more efficient and is mainly used in coking enterprises. It uses circulating inert gas as a heat carrier. The cold gas is sent into the red coke cooling chamber through a circulating fan to cool the high-temperature coke to below 250°C. Then, the circulating hot gas that absorbs heat is introduced into the waste heat boiler to recover the heat and generate steam. After the cooled gas is dust-removed, it is sent back to the cooling chamber by the fan again, forming a circulating cooling process, which allows the red coke to be effectively cooled. Therefore, the quenching efficiency can be improved by combining dry and wet methods.

[0004] During use of the existing dry-wet combined quenching device, it was found that during the wet quenching process, the position of the nozzle was fixed, resulting in a limited spraying range.

[0064] Step 5: dry quenching, close the wet quenching unit 200, and transport the inert gas in the inert gas storage tank 301 to the coke hood through the pump body 3011 to complete the dry quenching operation.

[0065] The implementation principle of a dry-wet combined coke quenching device and process of this embodiment is as follows:

[0066] Open the feed door 1013, put the coke to be quenched into the quenching hood 101, and place the coke as a whole on the filter plate 103, then open the discharge pipe 104, and inject water into the nozzle 2051 through the water tank 2054. The nozzle 2051 sprinkles water on the coke to achieve the quenching effect.

[0067] Then, the hydraulic push rod 201 is started, and the mounting cover 202 connected through the fixing seat 2011 is driven to move by the hydraulic push rod 201, and the structural strength of the connection is improved by the inclined plate 2012. The movement of the mounting cover 202 can drive the connecting bracket 2021 to move, and the position of the positioning gear 203 on the connecting bracket 2021 changes synchronously, and the positioning gear 203 slides on the positioning rack 2031, which can drive the positioning gear 203 itself to rotate, and finally drive the position of the sliding rod 2032 on the positioning gear 203 to change, and the bar groove 2041 on the swing arm 204 slides in the sliding rod 2032. The swing arm 204 is moved, and then the swing arm 204 swings back and forth, and the swing arm 204 drives the rotating shaft 2042 to rotate, and the rotating shaft 2042 can drive the fixed rod 2052 to rotate. The fixed rod 2052, which can adjust the length, is convenient for adjusting the spraying height. When the fixed rod 2052 rotates, the collecting cover 205 equipped with the nozzle 2051 can be driven to swing, and then the pitch angle of the nozzle 2051 can be driven to change, thereby increasing the spraying range. The entire wet quenching unit 200 moves inside the quenching cover 101, which can drive the nozzle 2051 to move horizontally, further increasing the spraying range, reducing the spraying dead angle, and making the quenching more complete.

[0068] During the rotation of the positioning gear 203, the shifting roller 206 is driven to rotate, and the position of the cylindrical cam groove 2061 on the shifting roller 206 changes synchronously. At this time, the cylindrical cam groove 2061 can drive the limited shifting slider 2062 to slide. The shifting slider 2062 slides along the fixed limiting rod 2063 at this time, and can squeeze the reset spring 2064 on the limiting rod 2063, so that the reset operation can be facilitated later through the reset spring 2064.

[0069] The shifting slider 2062 drives the stirring column 208 to move. At this time, the stirring column 208 moves in the coke, so that the coke at different positions is mixed, which is convenient for the water mist and the coke to fully contact, and the stirring column 208 as a whole slides along the positioning plate 207. The guide protrusion 2071 on the positioning plate 207 will squeeze the insertion rod 209 to move vertically, and the pressure plate 2091 on the insertion rod 209 will press downward. The pressure plate 2091 and the partition 2082 can squeeze the extrusion spring 2092, and the extrusion spring 2092 is convenient for later resetting.

[0070] When the insertion rod 209 moves downward, the insertion rod 209 has a downward squeezing force on the rocker arm 2112, and the rocker arm 2112 tilts, thereby driving the slide plate 211 to slide along the guide rod 2111, and the slide plate 211 squeezes the rocker arm 2104, and the rocker arm 2104 rotates around the positioning shaft 2103, and the side rod 210 connected to the positioning shaft 2103 rotates synchronously, so that the first stirring plate 2101 and the second stirring plate 2102 on the side rod 210 begin to swing, so that the stirring is more sufficient, thereby improving the quenching efficiency.

[0071] When the wet quenching unit 200 is completed, the operator pumps the inert gas in the inert gas storage tank 301 to the inside of the coke hood, completing the dry quenching operation.
