Abstract
The utility model discloses an air damp door of a flue, comprising a baffle door. The baffle door is connected with a rack transmission device and is driven to move up and down by the rack transmission device. The vertical direction of the baffle door is provided with a guiding location part, the horizontal direction is provided with two treadle bars, and the treadle bars are fixed and compacted with sealing rubber strips. The baffle door moves up and door through the driving of the rack transmission device, and is located and guided by utilizing the guiding location part in up and down moving. Flue gas is sealed by the sealing rubber strips, and the treadle bars are fixed and compacted with the sealing rubber strips, therefore, the utility model has the advantages of tight sealing, stable operation, little maintenance and long operating time.
Description
Technical field
The utility model relates to a kind of flue wind blocking door, is applicable to the technical field of boiler exhaust gas passage and flue gas desulfurization passage.
Background technology
At present, in boiler exhaust gas and the flue gas desulfurization production run, in order to cut off, open wide the circulation area of flue and adjustment flue, the general wind blocking door that adopts is controlled, thereby reaches the purpose of adjusting exhaust gas volumn at home.Domestic existing wind blocking door roughly has two kinds: the one, and easy board plug type wind blocking door; The 2nd, inner turnover plate type wind blocking door.Adopt easy board plug type wind blocking door serious to surface air leakage usually; Inner turnover plate type wind blocking door, the air that adopts seal fan to provide is pushed down interior panelling, and interior panelling causes interior panelling to contact and closes because the air pressure that frequent dust stratification and seal fan provide is less than normal, and leakage is serious, and influence is operation normally.Inner turnover plate type wind blocking door, because with sealing wind sealing baffle, air supply duct must be arranged, steel consumption height, the corresponding investment cost that increased, and seal fan moves constantly, corresponding operating cost and maintenance cost are higher, and when inner dust stratification, inner turnover panel is closed not in place, even can't close, had a strong impact on operation.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of flue wind blocking door simple in structure, easy to use is provided.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of flue wind blocking door comprises a baffle door, and this baffle door is connected with rack gearing, is driven by rack gearing to move up and down; Vertical direction is provided with guide-localization parts; Horizontal direction is provided with two press strips; Sealing rubber strip is fixed and compressed to press strip.
Baffle door moves up and down the adjustment throttle opening by the driving of rack gearing, utilizes the guide-localization parts to position when moving up and down and leads, and flue gas is sealed by sealing rubber strip, sealing rubber strip is fixed and compressed to press strip, make sealing tight, stable, safeguard less, long operational time.
The beneficial effects of the utility model are: running quality simple in structure, easy to use, as to improve wind blocking door, reduce investment, and reduce maintenance cost, energy savings.
