Description
Technical Field
The utility model relates to a scalable atomizer of ou ye stove.
Background
In order to realize the functions of energy conservation and environmental protection, the Ou-Meta furnace modifies a COREX top gas filling washer and an adjustable venturi washer into a gravity dust removal and dry dust removal system. The method adopts a dry dust removal gas purification process to replace the original COREX shaft furnace gas wet dust removal process, the normal working temperature of the top of the shaft furnace ranges from 150 ℃ to 280 ℃, if the temperature fluctuates in case of furnace conditions, the temperature of the top gas of the shaft furnace can reach 600 ℃ under abnormal working conditions, and because a dry dust removal cloth bag can only adapt to the working conditions of about 200 ℃, otherwise, the cloth bag is burnt or the service life of the cloth bag dust remover is shortened, and the gas quality and the normal production of the Europe and metallurgy furnace are influenced. The technical scheme at the initial blowing-in stage of the Euler furnace is that a water spraying device is arranged at the top of the shaft furnace, but although the temperature of the furnace top is controlled within a range, the service life of a core component nozzle of the water spraying device is short, and the water spraying nozzle is easy to burn and crack under the working conditions of high-temperature environment and alternating temperature of the furnace top of the shaft furnace, so that the water spraying nozzle cannot be normally used and normal production is influenced. Meanwhile, the nozzle can not effectively atomize liquid water after cracking, the cooling is not uniform, the water can not be uniformly mixed with the coal gas, and the effect of reducing the temperature of the coal gas can not be achieved.
Disclosure of Invention
An object of the utility model is to provide a scalable atomizer of eupatorium stove can adapt to the operating mode condition of reversal, and the atomizing is even, protects the resistant material of furnace roof, prevents that the furnace charge from bonding and sack dust collecting equipment from damaging.
The purpose of the utility model is realized like this: a telescopic spraying device of an Ou metallurgical furnace comprises a water channel shell installed on a shaft furnace through a large sealing flange, wherein a water inlet flange is arranged at the end part of a water inlet pipe of the water channel shell, a positioning sleeve is fixedly sleeved in the water channel shell close to an outlet, a nozzle water channel inner shell is sleeved in the positioning sleeve in a sliding fit manner, a compression spring is sleeved on the shell of the nozzle water channel inner shell in the positioning sleeve, an annular retaining shoulder is arranged in the positioning sleeve, an annular space is formed between the positioning sleeve and the nozzle water channel inner shell, one end of the compression spring is abutted against the annular retaining shoulder, the compression spring is positioned in the annular space, a sliding block piston is sleeved at the outer side part of the nozzle water channel inner shell, two sealing rings are arranged on the outer peripheral surface of the sliding block piston, the sealing rings are in sealing fit with the inner peripheral wall of the water channel, the sliding sleeve periphery wall is inlayed and is equipped with the sealing washer, and this sealing washer is sealed with the interior perisporium of water course casing and is cooperated, and nozzle water course inner shell outside end is fixed and is being set up atomizing nozzle, and atomizing nozzle is driven by nozzle water course inner shell and is slided in the water course casing.
The utility model discloses the during operation is linked together the flange of will intaking with high-pressure water pipe, and in the high pressure water injected nozzle water course, promote the outside motion of nozzle water course inner shell, atomizer's atomising nozzle accessible atomized water's pressure does work, moves the atomising nozzle to atomizer's front end, ensures to have sufficient spraying area. The spray nozzle of the spraying device can do work through spring force, the spray nozzle is moved to the inside of the spraying device, and the spray nozzle is enabled to retract into the inside of the spraying device when not working, so that the spray nozzle is not failed due to long-term baking and heating of high-temperature coal gas. Through the structural adjustment of the atomizing nozzle, the coverage area of atomized water mist is large. The maximum atomization diameter of the atomization nozzle can reach 3-4 um, the atomization nozzle can be mixed with coal gas more fully, the coal gas cooling and quantity regulation are facilitated, and the atomization particles are basically kept unchanged in the whole water quantity variation range. The energy is saved obviously, and the micro atomization can be realized under the condition of lower water pressure. The front end face of the inner shell of the sliding block piston and the nozzle water channel forms a certain working area, so that the atomizing water pressure can effectively overcome double resistance formed by friction resistance and pressure in the shaft furnace, and effectively work to compress the spring to push the nozzle water channel to move towards the inside of the shaft furnace. After the pressure of atomized water is lost, the nozzle water channel can move out of the furnace by the expansion work of the spring force. The furnace top atomization device has long service life, can adapt to the high temperature of the furnace top of the shaft furnace and the alternating working conditions, atomizes uniformly, protects the refractory material of the furnace top, and prevents the bonding of furnace materials and the damage of cloth bag dust removal equipment.
