Embodiment approach 1

[0028] Implementation of a gas-liquid two-phase distributor provided by the present invention includes an existing gas distribution tower 1 and a liquid distribution plate 5; its specific implementation is as follows:

[0029] A gas-liquid two-phase distributor 22 is composed of a gas distribution tower 1 and a liquid distribution plate 5 connected through a gas-liquid separation tank 3; a number of " S" type liquid seal pipe 15, several cooling water nozzles 14 are evenly distributed on the lower end surface; circular liquid storage distribution tank 10 is used to store the liquid separated by "S" type liquid seal pipe 15, and passes through the small hole of the bottom plate The cooling water nozzle 14 connected to the hole is used for spraying distribution; the upper port of the "S" type liquid seal pipe 15 is connected to the lower liquid hole at the bottom of the gas-liquid separation tank 3, and the lower liquid hole is used for cooling water to enter the "S" type liquid ...

specific Embodiment approach

[0037] Implementation of a coke quenching oven that uses a gas-liquid two-phase distributor 22 provided by the present invention, the coke quenching oven is to apply the gas-liquid two-phase distributor 22 to a coke quenching oven, and the coke quenching oven is sequentially controlled by high temperature Coke pre-storage area 19, high-temperature coke and gaseous cooling medium reverse cross-flow contact first cooling area 21, cooling medium distribution area 29, hot coke co-flow liquid cooling medium uniformly sprayed radially, second cooling area 23 and discharge area 24 The high-temperature mixed gas outlet 30 is arranged on the upper end of the upper mixed gas channel 20 where the high-temperature coke and the gaseous cooling medium cross-flow in reverse and contact the first cooling zone 21; the gas-liquid two-phase distributor 22, the mixed gas inlet 2 and the liquid inlet 4 are arranged on Coke quenching oven cooling medium distribution area 29. Its structure is to ins...

Embodiment approach 3

[0050]The conditions of the experimental device in this embodiment are: the height of the high-temperature coke pre-storage area 19 is 900 mm, the inner diameter is 600 mm, the top cover is lined with a steel plate of heat-insulating material, there is a valve at the connection between the high-temperature coke pre-storage area 19 and the cooling area, and the inner diameter of the valve is Ф300. There are 150mm high and 45°C sloping conical cylinders at the top and bottom, so that the gas can be better exported to the quenching oven; when coke is put into the high-temperature coke pre-storage area 19, the valve is closed, and a valve is opened 5mm below the valve. High-temperature mixed gas outlet 30; cooling zone height 1200mm, internal diameter 600mm, discharge zone 24 height 300mm, outlet diameter 150mm; the bottom of gas-liquid two-phase distributor 22 with three-layer conical carbon baffle plate 8 is located at 800mm from the upper valve, the gas The liquid two-phase dist...

Abstract

Disclosed are a gas-liquid two-phase distributor and a coke quenching furnace using the same. The gas-liquid two-phase distributor is arranged in the coke quenching furnace. The gas-liquid two-phase distributor is formed by communication of a gas distribution tower and a liquid distribution disc through a gas-liquid separation tank, and is supported in the middle of the coke quenching furnace through a support rod fixed on the inner wall of the coke quenching furnace. The gas-liquid two-phase distributor is small in resistance and large in flow, and enables a gas-liquid even distribution area to be formed in the coke quenching furnace. The coke quenching furnace utilizes gas-liquid two-phase distribution, multi-step quenching and mixed cooling medium circulation quenching, and is high in quenching efficiency, strong in processing capacity, and wide in application range.

Description

technical field [0001] The invention relates to a gas-liquid two-phase distributor and a coke quenching oven thereof, in particular to a gas-liquid two-phase distribution coke quenching oven in which a gas-liquid two-phase distributor communicates with gas and liquid. technical background [0002] US 4437936, the United States patent discloses "process for utilizing waste heat and for obtaining water gas during the cooling of incandescent coke". The device is composed of a pre-chamber, a cooling chamber, a quenching chamber, and a discharge chamber; the medium-temperature coke is cooled by spraying cooling water mist into the quenching chamber, and the coke releases a large amount of heat during the cooling process, making the cooling water vapor Turned into water vapor, part of the water vapor rises, and in the process of rising, the water vapor reacts with red hot coke to generate synthesis gas. The syngas, water vapor and some other dust are exported from the high-temper...
