Abstract
The utility model relates to an automatic compensation device for radial seal of an air pre-heater. The automatic compensation device is composed of a hinge type seal sliding block and a sector plate lifting automatic control device. The hinge type seal sliding block is installed on the side face of a shifting board of the air pre-heater. The sector plate lifting automatic control device is composed of a sector plate lifting actuator and an electrical control cabinet. The sector plate lifting actuator is installed on a truss of the air pre-heater and is connected with a sector plate through a connecting rod. The electrical control cabinet is installed on an operation platform of the air pre-heater. The sector plate lifting actuator and the electrical control cabinet are connected through a wire. The automatic compensation device for radial seal of the air pre-heater is compact in structure, reasonable in design, flexible in response, convenient to maintain and use, high in compensation precision, stable in operation, and capable of effectively lowering radial air leakage of the air pre-heater, realizing control over radial air leakage of the air pre-heater, and effectively lowering the air leakage rate of the air pre-heater.
Description
Technical field
The utility model relates to a kind of automation field, especially relates to a kind of air preheater radial seal autocompensation installation.
Background technology
At present, rotary regenerative air preheater is a visual plant in modern thermal power plant, its height that leaks out is the fatal shortcoming of this equipment, can greatly reduce the economic benefit of factory, thereby its air leak rate of air curtain is to weigh an important indicator of air preheater manufacturing technology and performance driving economy.The leaking out of air preheater comprise radially leak out, axially leak out, bypass leaks out and carries and leak out etc., wherein radially leak out and account for 70% of total inleakage, but radially air leak rate of air curtain height is very scabrous, so how radially the leaking out of reduction air preheater of maximum possible is the most important thing of Air leakage control technology.
Summary of the invention
The purpose of this utility model is to overcome the weak point existing in above-mentioned technology, a kind of compact conformation, reasonable in design is provided, working stability, can effectively reduce air preheater and radially leak out, and keeps in repair air preheater radial seal autocompensation installation easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is: be made up of hinge type sealing slide block and fanning strip lifting automaton, described hinge type sealing slide block is arranged on the shifting board side of air preheater, described fanning strip lifting automaton is made up of fanning strip lifting executing agency and electrical control cabinet, described fanning strip lifting executing agency is arranged on air preheater truss, fanning strip lifting executing agency is connected with fanning strip by connecting rod, described electrical control cabinet is arranged on air preheater operating platform, fanning strip lifting executing agency is connected by wire with electrical control cabinet.
The utility model has the advantages that:
Compact conformation, reasonable in design, is quick on the draw, and keeps in repair easy to usely, and compensation precision is high, and working stability can effectively reduce air preheater and radially leak out, and can realize the radially Air leakage control of air preheater, effectively reduces the air leak rate of air curtain of air preheater.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is made up of hinge type sealing slide block 1 and fanning strip lifting automaton, described hinge type sealing slide block 1 is arranged on the shifting board side of air preheater, described fanning strip lifting automaton is made up of fanning strip lifting executing agency 3 and electrical control cabinet 4, described fanning strip lifting executing agency 3 is arranged on air preheater truss, fanning strip lifting executing agency 3 is connected with fanning strip 2 by connecting rod, described electrical control cabinet 4 is arranged on air preheater operating platform, fanning strip lifting executing agency 3 is connected by wire with electrical control cabinet 4.
Air preheater radial seal autocompensation installation of the present utility model is made up of two parts, a part is hinge type sealing slide block 1, another part is fanning strip lifting automaton, hinge type sealing slide block 1 is arranged on the shifting board side of air preheater, fanning strip lifting automaton is made up of fanning strip lifting executing agency 3 and electrical control cabinet 4, fanning strip lifting executing agency 3 is arranged on air preheater truss, fanning strip elevating mechanism 3 is connected with fanning strip 2 by connecting rod, electrical control cabinet 4 is arranged on air preheater operating platform, fanning strip lifting executing agency 3 is connected by wire with electrical control cabinet 4, fanning strip lifting executing agency 3 is connected by wire with electrical control cabinet 4.After air preheater operation, hot end of rotor is radially expanded degree and is greater than cold junction, air preheater central shaft in the time of hot operation upwards expands simultaneously, the deadweight that adds upper rotor part is very large, so air preheater there will be the rotor periphery mushroom shaped of distortion downwards in the time of hot operation, thereby produces radial clearance.Now, electrical control cabinet 4 provides instruction, fanning strip lifting executing agency 3 moves, by connecting rod, fanning strip 2 is transferred to stopping apart from radial seal agreement that contracts a film or TV play to an actor or actress 5mm-8mm place, hinge type sealing slide block 1 contacts with fanning strip 2 gaplesss and forms sealing, can effectively reduce the radially air leak rate of air curtain of air preheater.Treat that unit load increases, the mushroom distortion that air preheater produces can strengthen, and radial clearance increases thereupon, and autocompensation installation repeats said process automatically, can complete the sealing of radially leaking out of air preheater, thereby reduce in time the radially air leak rate of air curtain of air preheater.
