Description
Technical field
The utility model belongs to desulphurization plant technical field, specifically a kind of movable melt pit cover board arrangement.
Background technology
With the fast development of China's economy, electricity needs constantly increases, and disposal of pollutants also constantly increases.According to related research
It points out, China's about hundreds of millions yuan of economic loss caused by disposal of pollutants every year, economic loss about 5000 caused by Acid Rain Pollution
Hundred million yuan.With industrial expansion and the improvement of people's living standards, the craving of the energy is also continuously increased, in coal-fired flue-gas
SO2The main reason for having become atmosphere pollution, power industry control SO2The task of discharge is still severe.Therefore, power-plant flue gas
Desulfurization technology is particularly important.
At present there are many fume desulphurization method in industry, wherein it is that Gypsum Wet flue gas takes off that application is relatively broad
Sulphur, principle are that slurries are made as desulfurization absorbent using agstone, are mixed in absorption tower with the smoke contacts of entrance,
Calcium carbonate in sulfur dioxide and slurries in flue gas and the oxidation air blasted are chemically reacted, and end reaction is main
By-product is gypsum.Desulfuration absorbing tower melt pit system refers to a melt pit in desulfuration absorbing tower regional extent, is responsible for collecting and inhale
Each component cooling water in tower region, machine water shutoff, overflow slurry, flushing water etc. are received, so as to which slurries be avoided to waste, saves production cost,
Melt pit cover board is then the lid, cover or top for closing or covering melt pit outlet end or top.Usually in melt pit in production practices
Manhole steel deck-plate is set in outlet, and when inspection melt pit equipment can carry out maintenance dimension by opening the manhole steel deck-plate to internal unit
Shield.The weight of current manhole steel deck-plate needs two people to be opened simultaneously using the lift of cover board handrail, its melt pit equipment can be examined
Running equipment in maintenance or inspection melt pit is repaiied, use is extremely inconvenient.When a people makes an inspection tour equipment, then it is difficult to open cover board, is only capable of
Pit stirrer top speed reducer, motor and sump pump upper motor etc. are maked an inspection tour, can not further check blender axis in operation
And blade etc., it may cause only to make an inspection tour melt pit surface equipment in the course of time, ignore running equipment in melt pit；Secondly, current lid
After plate is opened, also need to prevent falling from high altitude problem in detection process, production security needs to be further improved.
Through retrieval, the structure on absorption tower melt pit cover board is improved, and existing related patents disclose at present.Such as Chinese patent
Application number：2012202863774, the applying date：On June 9th, 2012, invention and created name are：Cover board, this application discloses one
Kind cover board, for being closed box opening, including：The main cover plate and activity for being covered in box opening are fixed on main cover plate
The auxiliary cover board of side, main cover plate include preliminary examination through hole, and auxiliary cover board covers preliminary examination through hole.When this application needs article in detection case body
It waits, without cutting off cover board, avoids cutting off the additional heavy industry caused by cover board, improve the ability to dismantle of cover board；But this application
Auxiliary cover board simply cover on preliminary examination through hole, not there are one good support, and open it is not convenient enough.
