Double-U-shaped smoke guiding pipe dedusting car of tamping coke furnace

Abstract

The invention relates to a double-U-shaped smoke guiding pipe dedusting car of a tamping coke furnace, comprising car-body steel structure, a travelling device, smoke guiding pipes, an ascending tube operating device, an ascending tube sweeping device, an electronic control room, a hydraulic pressure room and a driver cab. The double-U-shaped smoke guiding pipe dedusting car is characterized in that the car-body steel structure forms framework of the whole car, two travelling beams are arranged at the lower part of a car body, the travelling device is installed on the car body, the driver cab is arranged at the lower part of the car-body steel structure, a platform at the upper part of the steel structure is provided with the smoke guiding pipe A, the smoke guiding pipe B, the electronic control room, the hydraulic pressure room, ascending tube operating device and the ascending tube sweeping device. The double-U-shaped smoke guiding pipe dedusting car has the advantages of simple structure, good dedusting effect, wide application region, strong seasonal applicability and good environmental protection effect. The smoke guiding pipe dedusting car is not needed to be provided with a furnace top dedusting ground station system and a combustion washing-type dedusting car with complicated structure, but utilizes the original gas system of the coke furnace to be switched with high-low ammonia water to lead the charged flue gas to be introduced into a gas collecting system in a controllable way through 1-3 channels by the smoke guiding pipe dedusting car, thus achieving the aims of recovering the gas, eliminating atmospheric pollution and protecting the environment of factory production and surrounding residents.

Description

technical field [0001] The invention belongs to the technical field of coke oven dust removal, in particular to a tamping coke oven double U-shaped smoke guide pipe dust removal vehicle, which is suitable for smoke and dust removal on the top of 4.3-6.25m tamping coke oven, and can also be used for 3.2-3.8m The technical transformation of the old coke oven smoke and dust removal vehicle is underway. Background technique [0002] The currently used tamping coke oven dedusting vehicles are as follows: [0003] 1. Combustion washing type dust removal vehicle, which can extract the furnace flue gas from the carbonization chamber through the fan, collect it into the combustion chamber for combustion, and discharge it to the atmosphere after washing and cooling, separation of steam and water, dust removal and filtration, the structure is complex, and the water system in winter Freezing equipment is difficult to use normally. [0004] 2. Dry-type dedusting vehicle. Furnace loadin...

AI Technical Summary

Problems solved by technology

[0003] 1. Combustion washing type dust removal vehicle, which can extract the furnace flue gas from the carbonization chamber through the fan, collect it into the combustion chamber for combustion, and discharge it to the atmosphere after washing and cooling, separation of steam and water, dust removal and filtration, the structure is complex, and the water system in winter Icing equipment is difficult to use normally

[0004] 2. Dry-type dedusting vehicle. Furnace loading flue gas of this vehicle relies on the fan of the dedusting station on the floor of the coke oven and the huge bag dust removal system to extract the furnace-loading flue gas through the dry dedusting vehicle, and passes through the dedusting drying along the entire length of the coke oven The pipe is introduced into the ground station for filtration. In order to reduce the temperature of the flue gas, there are flue gas adjustment and air conditioning devices on the dust removal vehicle. This kind of dust removal vehicle has a better dust removal effect than the combustion and washing type dust removal vehicle. complex, long construction period

The disadvantage is that the dust removal effect is not ideal, and it cannot meet the environmental protection requirements.
