Abstract
The present invention belongs to the field of environment protecting technology, and is especially one converter shop dust collecting cover device. The converter shop dust collecting cover device is set over the steel making converter for collecting secondary fume of the converter and ventilating the converter shop. The converter shop dust collecting cover device is one vertical shaft steel structure with valve combination for airflow direction change. When the converter shop dust collecting cover device is used for ventilating the converter shop, the valve to the atmosphere is opened while the dedusting valve to the dedusting system is closed. When it is used for dedusting fume, the valve to the atmosphere is closed while the dedusting valve to the dedusting system is opened for conveying the fume to the dedusting system. The valve combination is pneumatically interlinked.
Description
Technical field
The invention belongs to the environmental protection equipment technical field, be specially a kind of essemer converter factory building dormer cover dust arrester installation.This device both can effectively capture the converter secondary flue gas, can carry out the ventilation of factory building dormer formula to the steel-making hot shop again.
Background technology
At present, a lot of steelmaking converter flue gas ash removal effects are undesirable, the analysis of tracing it to its cause, and the most basic one is exactly to lack the flue gas of converter when the hot metal charging effectively captured.
The high concentration flue gas of overflowing from fire door when existing converter mill generally can't be to the converter hot metal charging effectively captures.Reason is that converter converts iron when operation converter mouth and tilt to the ladle direction, when ladle is toppled over molten iron in stove and the fire door close together.Can't be provided with petticoat pipe around and the dirt source be carried out effectively airtight this moment.Hot metal charging when operation because of high temperature liquid iron from eminence flow at high speed in stove, the contrary molten iron flow direction of a large amount of high concentration flue dust of generation flows.Because of the flue gas flow rate height, belong to the paroxysmal flue dust, the flue gas trapping difficulty.But this part dust concentration height, instantaneous generating capacity are big, and particularly along with the converter smelting cycle shortens, the flue dust total amount is big, and is serious to the workshop internal contamination.Its flue gas trapping more and more comes into one's own.
Existing converter dust-removing technology can only rely on enclosed hood or roof petticoat pipe around the converter to capture for the flue gas of converter when the hot metal charging.The converter enclosed hood can't effectively capture the flue gas that converter escapes when hot metal charging, conventional roof petticoat pipe is with the sealing of converter hot metal charging side roof, and the roof petticoat pipe is set, and this type structure complexity, takies the roofing area, because of the workshop sealing, indoor environmental condition is poor after the hot metal charging end of job.
The converter shop dust collecting cover device that the present invention proposes, escape phenomenon at the flue gas of converter when the hot metal charging exactly, utilize the design of factory building dormer ventilation, carry out Creative Design, make it both can effectively capture the converter secondary flue gas, can utilize the factory building discrepancy in elevation again, carry out dormer formula gravity-flow ventilation ventilation, effectively improve environment in the workshop, energy savings.
Summary of the invention
Of the present inventionly be to provide a kind of and not only can have effectively captured the converter secondary flue gas, but also can improve the converter shop dust collecting cover device of environment in the workshop.
The converter shop dust collecting cover device that the present invention proposes is that the original ventilation dormer in converter mill is improved, and specifically is that air shaft is set, and utilizes the switching of triple valve group, satisfies the capture of converter hot metal charging flue gas and gravity-flow ventilation requirement at ordinary times.
Converter shop dust collecting cover device of the present invention is located at the steelmaking converter top, is exclusively used in escaping flue gas and improving workshop condition when capturing the converter hot metal charging.It is made up of ventilation dormer, air shaft, switch valve, dedusting valve and cleaning shaft, and its structure as shown in Figure 1.Wherein, air shaft 2 is arranged in the ventilation dormer 3, and is communicated with the converter factory building; Cleaning shaft 5 one ends are arranged at the middle part of air shaft 2, and an end leads to dust pelletizing system; Switch valve 1 is arranged in the air shaft 2 interface corresponding to cleaning shaft 5; Dedusting valve 4 is arranged at the exit that cleaning shaft 5 leads to dust pelletizing system.
Among the present invention, dormer cover (being air shaft) is designed to vertical shaft type, and adopts steel construction.Switch valve 1 and dedusting valve are formed valve sets, are used for control and switch air flow direction in the vertical shaft type dormer cover.When converter shop dust collecting cover device is used to make steel hot shop when carrying out the ventilation of dormer formula, the switch valve 1 that leads to atmosphere in the valve sets is opened, and the dedusting valve 4 that leads to dust pelletizing system is closed automatically; During flue gas ash removal when converter shop dust collecting cover device is used to the converter hot metal charging, lead to the switch valve 1 of atmosphere in the valve sets, be closed, and the dedusting valve 4 that leads to dust pelletizing system is opened automatically, flue gas is sent into dust pelletizing system purify; Valve sets adopts pneumatic interlocking.
Among the present invention, can be set up in parallel a plurality of cleaning shafts 5 (being generally 1-4) according to the width of air shaft 2, each cleaning shaft is provided with switch valve 1 and dedusting valve 4 respectively.
Novel practical of the present invention, simple in structure, easy to operate both can satisfy capture and purification to ash-laden gas, can utilize gravity-flow ventilation to get rid of the interior waste heat of factory building again.It is a kind of efficient, energy-conservation flue gas trapping device.

The specific embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described.
If the cross section of air shaft 2 is a rectangle, be of a size of 15 * 4m, be set up in parallel in the middle part of air shaft 2 and establish 3 cleaning shaft 5 interfaces, the cleaning shaft cross section also is a rectangle, in the air shaft 2, the interface of corresponding cleaning shaft 5 is provided with 3 switch valves 1 respectively, and each switch valve 1 is of a size of 6 * 4m.Cleaning shaft 5 is of a size of 1.5 * 1.5m, in 3 cleaning shafts 5 dedusting valve 4 is set respectively, is of a size of 1.5 * 1.5m.Switch valve and dedusting valve all adopt three-way valve.Wherein, the structure of switch valve 1 as shown in Figure 4.It is made up of valve body 10, connecting rod 9 and valve cylinder 8.Whole dust arrester installation is arranged at the top of converter mill steelmaking converter, assembles as shown in Figure 2.
When gravity-flow ventilation, the switch valve 1 in the three-way valve group is opened, and dedusting valve 4 is closed, and the thermal current in the steelshop diffuses outside the factory building by vertical shaft type ventilation dormer 3; When the converter secondary flue gas was captured, the switch valve 1 in the three-way valve group was closed, and dedusting valve 4 is opened, and the ash-laden gas in the steelshop enters dust pelletizing system by cleaning shaft 5 and carries out purified treatment.
