Abstract
A waste heat utilization desulphurization air door for positive-pressure and negative-pressure flues relates to a baffle plate door for insulating flue gas in a flue desulphurization system. A flue waste heat recovery air heater system is used for replacing the prior-art air electric heater system, thereby providing a heat source for sealed air. A sealed air curtain is formed through filling hot air in a chamber of the baffle plate after the baffle plate is closed, thereby realizing flue gas insulation. The waste heat utilization desulphurization air door has the following advantages: compact structure, easy and reliable operation, high convenience in maintenance, reduced energy consumption and environment-friendly performance.
Description
Technical field
The utility model relates to a kind of flue gas desulfurization device, particularly a kind of flue gas desulphurization system smoke gas isolating type baffle door that is used for.
Background technology
Be used for the normally two shutters of multiaxis of baffle door that the flue gas desulphurization system flue gas isolates at present, realize isolating fully through 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 from baffle plate sealing surface gap, overflowed, and played the effect of isolated flue gas.Problems such as what this traditional form provided sealing wind system thermal source is the electrical heating air heater, exists mechanism's complicacy, and system is loaded down with trivial details, and probability of malfunction is high, and energy consumption is big.
Summary of the invention
For overcoming the problem that exists in the existing sealing wind system, it is a kind of simple in structure that the utility model provides, at the bottom of the cost, and the desulfurization air door that energy consumption is little.
For realizing that the foregoing invention purpose can realize that a kind of positive negative pressure flue residue heat utilizes the desulfurization air door by following scheme, comprise the door body of sealing wind heating system and air door; The door body of described air door comprises that baffle plate, door frame, jointed gear unit, sealed tube form, and a body is arranged side by side in the door frame by a plurality of baffle plates, and wherein baffle plate is made up of axle, diaphragm seal, panel, baffle plate framework; The baffle plate framework is the strip framework of a cross section rectangle, and axle is positioned at the two ends of baffle plate framework, and panel is positioned at the surface of baffle plate framework; Diaphragm seal is positioned at four limits of panel, and the axle envelope is positioned at the axle output shaft position in the door frame outside, and bearing is positioned at axial end; Each is arranged on the straight line of door frame, and jointed gear unit links to each other with each, and sealed tube links to each other with the door frame top; When baffle door is closed; Each baffle plate arranges that linearly described air heater system is that flue residue heat reclaims air heating system, and described flue residue heat reclaims air heating system and comprises upper shell, bearing, tube sheet, heat pipe, gas approach flange, exhanst gas outlet flange, Taper Pipe, lower shell, sealing air suction flange, sealing air outlet(discharge) flange; Said bearing is connected in the lower shell bottom; Tube sheet is connected between upper shell and the lower shell, and the heat pipe radial arrangement is fixedly connected with tube sheet with the lower shell bosom in upper shell, and an end of Taper Pipe links to each other with lower shell with upper shell respectively; The gas approach flange is connected with Taper Pipe one end; The exhanst gas outlet flange is connected with Taper Pipe one end, and the sealing air suction flange is connected with Taper Pipe one end, and the sealing air outlet(discharge) flange is connected with Taper Pipe one end.
Operation principle of the utility model 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; Through 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 through the connecting rod rotating mechanism, and corner is harmonious each other.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 each other, forms mechanical seal.Seal wind system work simultaneously; Blower fan is opened normal temperature air is utilized the air heater lower shell through blower fan supercharging entering flue residue heat; Through with the upper shell heat exchange; Form high-temperature gas and charge in the baffle plate cavity, and from baffle plate sealing surface gap, overflow, form the isolated of flue gas through non-return valve, shut-off valve access door body.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 utlity model has simple in structure, simple and reliable for structure, power consumption energy-conserving and environment-protective, the beneficial effect that waits easy to maintenance.
