Description
Technical field
The utility model relates to a kind of portable fluorine removal device of electroslag fire door.
Background technology
Electroslag furnace is one of important smelting equipment producing high quality steel alloy, it can improve the purity of metal, improve the over-all properties of metal, but a large amount of smoking gas containing fluorines produced in electroslag furnace production process also bring serious pollution to atmospheric environment, general dust-removal system can be drawn onto in ash silo smelting the dust produced, but finally still can be discharged in atmospheric environment, this device can adsorb the fluorine gas produced in flue gas completely, finally by the chemical reaction removing fluorine gas in filter paper, such device belongs to metallurgical Electro Slag Remelting Steel and smelts novel appts field, environmental protection innovative means.
When Electro Slag Remelting Steel is smelted, dedusting is mainly by crystallizer cleaning shaft below, and this dedusting method is not for having effect fluorine gas often, because after being drawn onto ash silo, final fluorine gas still can be dispersed in air and go.According to Site Detection, adopt the electroslag furnace of CaF2/Al2O3 slag system refusion and smelting, fire door fluoride concn can up to 130mg/m
3, dust concentration 305mg/m
3, be far longer than the fluoride concn 1mg/m of the highest permission of country
3, dust 10mg/m
3requirement.This not only pollutes workshop condition, also causes tremendous influence to the health of employee.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to siphon away dust, and removing fluorine gas, ensures enterprise employee health, avoid the portable fluorine removal device of the electroslag fire door of environmental pollution.
The purpose of this utility model is achieved in that
The portable fluorine removal device of the utility model electroslag fire door, comprise moving body, roller is equipped with in the bottom of described moving body, the side-wall hole of described moving body is also equipped with dedust air duct, one end of this dedust air duct stretches out in moving body, the other end stretches in moving body inside, described moving body inside is fixed with suction fan in the one end relative to dedust air duct, filter mesh layer is provided with on rear side of the inherent dedust air duct of described moving body, this filter mesh layer is formed by multiple filter screen laid out in parallel, described filter screen applies NaOH, Na
2c0
3, CaO, is provided with dust-removal cloth-bag between described filter mesh layer and suction fan.
The beneficial effects of the utility model are:
The portable fluorine removal device of this electroslag fire door is Portable, convenient mobile operation, it is by being placed in the fire door of electroslag furnace by dedust air duct, start suction fan just flue gas out in stove to be passed in filter mesh layer and dust-removal cloth-bag and filter, fluorochemical in flue gas and dust all can be filtered, thus avoid fluorine gas and dust to enter workshop, avoid workshop condition contaminated, ensure that employee's is healthy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the portable fluorine removal device of the utility model electroslag fire door.
Wherein: moving body 1, roller 2, dedust air duct 3, suction fan 4, filter mesh layer 5, filter screen 6, dust-removal cloth-bag 7.
Embodiment
See Fig. 1, the utility model relates to a kind of portable fluorine removal device of electroslag fire door, comprise moving body 1, the bottom of described moving body 1 is equipped with roller 2 and can be moved with car body, the side-wall hole of described moving body 1 is also equipped with dedust air duct 3, one end of this dedust air duct 3 stretches out in moving body 1, it is inner that the other end stretches in moving body 1, described moving body 1 inside is fixed with suction fan 4 in the one end relative to dedust air duct 3, this suction fan 4 is for air draught, make dedust air duct 3 can by the flue gas inspiration moving body 1 in electroslag furnace, filter mesh layer 5 is provided with on rear side of the inherent dedust air duct 3 of described moving body 1, this filter mesh layer 5 is formed by multiple filter screen 6 laid out in parallel, described filter screen 6 is coated with alkaline chemical, as NaOH, Na
2c0
3, CaO etc., can be used for absorbing fluorochemical contained in flue gas, be provided with dust-removal cloth-bag 7 between described filter mesh layer 5 and suction fan 4, this dust-removal cloth-bag 7 is for siphoning away the dust in flue gas.
The portable fluorine removal device of this electroslag fire door is Portable, convenient mobile operation, it is by being placed in the fire door of electroslag furnace by dedust air duct, start suction fan just flue gas out in stove to be passed in filter mesh layer and dust-removal cloth-bag and filter, fluorochemical in flue gas and dust all can be filtered, thus avoid fluorine gas and dust to enter workshop, avoid workshop condition contaminated, ensure that employee's is healthy.
