Description

Telescopic spraying device of European smelting furnace
Technical Field
The invention relates to a telescopic spraying device of a European smelting furnace.
Background
In order to realize the functions of energy conservation and environmental protection, the Er-Mey furnace reforms a COREX top gas filler washer and an adjustable venturi scrubber into a gravity dust removal and dry dust removal system. The dry dedusting gas purification process is adopted to replace the original wet dedusting process of the COREX shaft furnace gas, the normal working temperature range of the furnace top of the shaft furnace is 150-280 ℃, if the furnace condition fluctuates, the temperature of the gas at the furnace top of the shaft furnace can reach 600 ℃ under the abnormal working condition, and the dry dedusting cloth bag can only adapt to the working condition of about 200 ℃, otherwise, the cloth bag is burnt or the service life of the cloth bag deduster is shortened, and the gas quality and the normal production of the European and metallurgical furnace are affected. The technical scheme of the initial stage of opening the furnace of the European smelting furnace is that a water spraying device is arranged at the top of the shaft furnace, but the temperature of the furnace top is controlled in a range, but the service life of a nozzle of a core component of the water spraying device is short, and the nozzle is easy to burn and crack under the working conditions of high temperature environment and temperature alternation of the furnace top of the shaft furnace, so that the furnace cannot be used normally, and normal production is influenced. Meanwhile, after the nozzle is cracked, the liquid water cannot be effectively atomized, the cooling is uneven, the water cannot be uniformly mixed with the gas, and the effect of reducing the temperature of the gas cannot be achieved.
Disclosure of Invention
The invention aims to provide a telescopic spraying device of an European and metallurgical furnace, which can adapt to alternating working conditions, is uniform in atomization, protects furnace top refractory materials, and prevents furnace burden adhesion and cloth bag dust removal equipment from being damaged.
The purpose of the invention is realized in the following way: the utility model provides a scalable atomizer of ouye stove, includes the water course casing of installing on the shaft furnace through sealed big flange, the inlet tube tip of water course casing is setting up into the water course casing internal fixation suit that is close to the export is setting up a section of locating sleeve, the intraductal slip fit suit of locating sleeve is being equipped with a nozzle water course inner shell, the intraductal compression spring that is located of locating sleeve of nozzle water course inner shell is being equipped with in the casing, the intraductal annular fender shoulder that has of locating sleeve, constitute the annular space between locating sleeve and the intraductal shell of nozzle water course, compression spring be located the annular space, the intraductal side of nozzle water course inner shell is being equipped with a slider piston, have two sealing washer on the slider piston periphery, sealing washer and the sealed cooperation of water course casing inner peripheral wall, the fixed suit is being equipped with a sliding sleeve on the intraductal peripheral wall of nozzle water course inner shell of locating sleeve outside end, the sealed cooperation of sealing washer and the inner peripheral wall of water course inner shell of sliding sleeve, the outside end fixed the nozzle of nozzle inner shell is being equipped with the atomizing nozzle, atomizing nozzle drives in the water course casing by the nozzle water course and slides in the water course.
When the spraying device works, the water inlet flange is communicated with the high-pressure water pipe, high-pressure water is injected into the nozzle water channel, the inner shell of the nozzle water channel is pushed to move outwards, the spraying nozzle of the spraying device can do work through the pressure of atomized water, and the spraying nozzle is moved to the front end of the spraying device, so that enough spraying area is ensured. The spray nozzle of the spraying device can do work through spring force, the spray nozzle is moved into the spraying device, and the spray nozzle is ensured to retract into the spraying device when not working, and is not heated by long-term baking of high-temperature gas to fail. 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 3um-4um, the atomization nozzle can be fully mixed with gas, the gas is favorable for cooling and regulating the quantity, and atomized particles basically keep unchanged in the whole water quantity change range. The energy is obviously saved, and the micro atomization can be realized under the condition of lower water pressure. The sliding block piston and the front end face of the nozzle water channel inner shell form a certain working area, so that the atomized water pressure can effectively overcome the friction resistance and the double resistance formed by the pressure in the shaft furnace, and effectively do work, compress the spring and push the nozzle water channel to move into the furnace. After the pressure of the atomized water is lost, the nozzle water channel can move outside the furnace through the expansion of the spring force. The device has long service life, can adapt to high temperature and alternating working conditions of the furnace top of the shaft furnace, is uniform in atomization, protects furnace top resistant materials, and prevents furnace burden from adhering and cloth bag dust removing equipment from being damaged.
