Abstract
The invention discloses a sealing device for a boiler rotary heater. The sealing device comprises a circular ring structure; two annular holes are formed on an air flue cover plate on the upper side of the heater, and the arc length of the two annular holes is 1/4 circumference of the concentric circle. The circular ring is arranged on the two annular holes which are formed on the air flue cover plate on the upper side of the heater; a semi-opening structure is welded with the air flue cover plate on the upper side of the heater; and the circular ring is propped tightly by a nut in a screwed hole of the semi-opening structure during running. A steam pipeline 3 passes through two symmetrical round holes in the circular ring; the circular ring moves in the symmetrical round holes along with the steam pipeline during rotation; and two screwed holes are formed on a long side of the semi-opening structure. The sealing device for the boiler rotary heater provided by the invention has the advantages of safety and reliability, convenient operation, and simple installation, can effectively prevent air leakage, and has good popularization and application value.
Description
Technical field
The present invention relates to boiler rotary air heater, relate in particular to the sealing device of a kind of boiler rotary air heater steam fairlead and air channel upper side cover.
Background technology
The boiler steam air heater is the heat transmission equipment that preheating enters the air preheater cold air, large-sized station boiler divides wind steam air heater and secondary wind steam air heater, its structure is identical with principle, and effect is to improve the air themperature that enters air preheater, prevents the cold end corrosion of air preheater low-temperature zone.That is to say that unless in the winter of cold, steam air heater does not need to put into operation in the most of the time in 1 year.Yet, even steam air heater does not put into operation, because still can there be resistance in the existence of steam air heater heat-transfer surface in the air channel.The appearance of rotary air heater preferably resolves this problem, but the operation of actual rotation is relatively more difficult, and is main because the layout more complicated of heat-transfer surface steam supply pipe and drain pipe.As previously mentioned, the import of rotary air heater is a steam, outlet is water, because the specific volume of water and steam is different,, and be arranged in the both sides of heat-transfer surface if steam supply pipe and drain pipe are a pipe, then the diameter of two pipes is different certainly, be the diameter that the diameter of steam supply pipe is greater than drain pipe, and in order to prevent short circuit, steam supply pipe and drain pipe can not be positioned at collinear position, heat-transfer surface both sides (coaxial).In order to conduct heat evenly, the structure of one every sheet heat radiator is that a side is arranged two steam inlet tubes, and opposite side is arranged a drain pipe, but this layout causes staying the annular distance that two jet chimneys are used to rotate on the cover plate of steam air heater upside air channel.No matter whether steam air heater moves, if annular distance is not handled, will cause leaking out, not only cause damage, also influence site environment.
Summary of the invention
The objective of the invention is to overcome above-mentioned prior art deficiency, a kind of steam air heater sealing device is provided.
Technical scheme of the present invention is achieved in that on the cover plate of steam air heater upside air channel and has two annular distances that the arc length of annular distance is 1/4 concentric circles girth; Annulus is placed on two annular distances of steam air heater upside air channel cover plate, half shape of the mouth as one speaks structure is connected with steam air heater upside air channel cover plate, utilizes the nut in the screwed hole of half shape of the mouth as one speaks structure that annulus is held out against during operation; Jet chimney passes in two symmetrical circular holes from annulus, and annulus moves in symmetrical circular hole with jet chimney.
Steam air heater needs rotation among the present invention, so annular distance that on the cover plate of the upside air channel of steam air heater, must have jet chimney to be used to rotate, in the process of rotary air heater, annulus is because of being enclosed within on the jet chimney, so can rotate together along with steam air heater, so just can guarantee no matter what state steam air heater is in, and can make annular distance be in sealing state.The present invention is not only safe and reliable, and is easy to operate, and installs simply, can prevent from effectively to leak out, and has the excellent popularization using value.
Description of drawings
Fig. 1 steam air heater is installed the schematic diagram behind the sealing device; Fig. 2 is the A-A cutaway view of Fig. 1.
Label among the figure is represented respectively: 1, steam air heater upside air channel cover plate; 2, annular distance; 3, jet chimney; 4, circular hole; 5, annulus; 6, nut; 7, half shape of the mouth as one speaks structure.
The specific embodiment
With reference to Fig. 1, shown in Figure 2, comprise an annulus 5, steam air heater upside air channel cover plate 1, some half shape of the mouth as one speaks structures 7 etc.Have two annular distances 2 on steam air heater upside air channel cover plate 1, the arc length of annular distance 2 is 1/4 concentric circles girth; Annulus 5 is placed on two annular distances 2 of steam air heater upside air channel cover plate 1, half shape of the mouth as one speaks structure 7 and 1 welding of steam air heater upside air channel cover plate then utilize the nut 6 in the screwed hole of half shape of the mouth as one speaks structure 7 that annulus 5 is held out against during operation; Jet chimney 3 has from annulus 5 in two symmetrical circular holes 4 and passes, and annulus 5 moves in symmetrical circular hole 4 with jet chimney 3 when rotation; Have two screwed holes on the long limit of half shape of the mouth as one speaks structure 7.As shown in Figure 2, some half shape of the mouth as one speaks structures 7 is characterized in that, have two screwed holes on the long limit of this structure, dual-side and the welding of steam air heater upside air channel cover plate.The sealing device guarantees the steam air heater rotation freely, and easy for installation, can rotate steam air heater in unit running process.
When rotary air heater is installed, annulus 5 is packed into jet chimney, two sides with some half shape of the mouth as one speaks structures 7 are welded on respectively on the steam air heater upside air channel cover plate 1 of annulus 5 bilateral symmetry positions then, and guarantee that annulus 5 can rotate with steam air heater in half shape of the mouth as one speaks structure 7.When putting into operation steam air heater, it is gone to the position of work after, with two screwed holes of nut 6 by half shape of the mouth as one speaks structure 7 annulus 5 is held out against (Fig. 2).In the time will stopping the rotation the steam air heater operation, nut 6 can be unclamped, at this moment rotary air heater is gone to suitable position, once more nut 6 is tightened.This structure can guarantee that not only steam air heater rotates freely, does not influence the operate as normal of steam air heater, and can prevent from effectively to leak out, and has the excellent popularization using value.
