Abstract
The invention discloses a desulfurizing air door for utilizing waste heat in a positive and negative pressure flue, which relates to a baffle door for blocking off flue gas in a flue desulfurizing system. According to the desulfurizing air door, a flue waste heat recovering air heater system is used to replace the traditional air electric heating system and provides a heat source for sealing air; and after the baffle is closed, hot air in filled in a baffle cavity to form a sealing air curtain, thus the separation of the flue gas is realized. The desulfurizing air door has the advantages of compact mechanism, simpleness and reliability for operation, convenience for maintenance, energy saving and environment friendliness.
Description
Technical field
The present invention relates to a kind of flue gas desulfurization device, particularly a kind of for flue gas desulphurization system smoke gas isolating type baffle door.
Background technology
Be used at present the normally two shutters of multiaxis of baffle door that the flue gas desulphurization system flue gas isolates, realize isolating fully by the flue gas that the sealing wind system provides hot secluding air to guarantee the baffle plate both sides.When baffle door was in buttoned-up status, all baffle plates went on the same plane, and middle hot sealing air is constantly charged in the baffle plate cavity, and overflowed from baffle plate sealing surface gap, played the effect of isolated flue gas.What this traditional form provided sealing wind system thermal source is the electrical heating air heater, exists mechanism's complexity, and system is loaded down with trivial details, probability of malfunction height, problem such as energy consumption is big.
Summary of the invention
For overcoming the problem that exists in the existing sealing wind system, the invention provides a kind of simple in structure, at the bottom of the cost, the desulfurization air door that energy consumption is little.
Can realize by following scheme for achieving the above object, a kind of positive negative pressure flue residue heat utilizes the desulfurization air door, the door body that comprises sealing wind heating system and air door, the door body of described air door is by baffle plate, door frame, jointed gear unit, sealed tube is formed, the door body is arranged side by side in the door frame by a plurality of baffle plates, wherein baffle plate is by axle, diaphragm seal, panel, the baffle plate framework is formed, the baffle plate framework is the strip framework of a cross section rectangle, axle is positioned at the two ends of baffle plate framework, panel is positioned at the surface of baffle plate framework, diaphragm seal is positioned at four limits of panel, the axle envelope is positioned at the axle output shaft position in the door frame outside, bearing is positioned at axial end, each is arranged on the straight line of door frame, jointed gear unit links to each other with each, sealed tube links to each other with the door frame top, when baffle door is closed, each baffle plate is linearly arranged, described air heater system is that flue residue heat reclaims air heating system, described flue residue heat reclaims air heating system and comprises upper shell, bearing, tube sheet, heat pipe, the gas approach flange, the exhanst gas outlet flange, Taper Pipe one, Taper Pipe two, Taper Pipe three, Taper Pipe four, lower shell, the sealing air suction flange, the sealing air outlet(discharge) flange, described bearing is connected in the lower shell bottom, tube sheet is connected between upper shell and the lower shell, the heat pipe radial arrangement is fixedlyed connected with tube sheet with the lower shell bosom in upper shell, Taper Pipe one, Taper Pipe two, Taper Pipe three, the big end of Taper Pipe four links to each other with lower shell with upper shell respectively, the gas approach flange is connected with Taper Pipe one small end, the exhanst gas outlet flange is connected with Taper Pipe two small ends, the sealing air suction flange is connected with Taper Pipe three small ends, and the sealing air outlet(discharge) flange is connected with Taper Pipe four small ends.
Operation principle of the present invention and process: flue residue heat utilizes the air heater upper shell to be the first flue gas loop, lower shell is sealing air secondary road, by heat pipe the fume high-temperature in the upper shell is conducted to the air in the lower shell, realize the heat temperature raising of sealing air.
The door body provides rotating torque by pneumatic or electric operator, guarantees a baffle plate parallel rotation by the connecting rod rotating mechanism, and corner is harmonious mutually.During sealing state, each baffle plate arranges that linearly the adjacent screen diaphragm seal overlaps mutually, and baffle plate and door frame diaphragm seal overlap mutually, forms mechanical seal.Seal wind system work simultaneously, the blower fan unlatching enters flue residue heat with normal temperature air by the blower fan supercharging and utilizes the air heater lower shell, by with the upper shell heat exchange, forming high-temperature gas charges in the baffle plate cavity by non-return valve, shut-off valve access door body, and from baffle plate sealing surface gap, overflow, form the isolated of flue gas.During unlatching, baffle plate is to counter-rotation, and diaphragm seal breaks away from overlap joint, and along with being rotated further of damper shaft, the door body is opened gradually, and shut-off valve cuts out, and blower fan cuts out, and the sealing wind system quits work.
Compare with existing air door, the present invention has simple in structure, and is simple and reliable for structure, power consumption energy-conserving and environment-protective, the beneficial effect that waits easy to maintenance.
