Abstract
The utility model discloses a bypassing automatic protective structure inside a dust remover, which comprises a bypassing air cylinder. The bypassing air cylinder is arranged on an upper box body of the dust remover, the bottom end of a bypassing air cylinder rod is connected with a bypassing valve plate provided with an internal bypassing flexible sealing strip, and an internal bypassing opening is closed by the internal bypassing flexible sealing strip. The bypassing automatic protective structure adopts an overhead bypassing structure, thereby realizing the automatic protection function of the internal bypassing.
Description
Technical field
The utility model relates to a kind of deduster structure, and particularly a kind of deduster internal bypass is protected structure automatically.
Background technology
The deduster internal bypass is the core component of deduster.At first, the deduster internal bypass adopts the underneath type structure, that is: stablize under the prerequisite of supply gas pressure at compressed air gas source, and the bypass cylinder promotes the link end valve plate and compresses the internal bypass mouth; When extreme case occurring, too high as flue-gas temperature, or the flue gas moisture content is when excessive, and the bypass cylinder raises up the bypass valve plate, and flue gas begins by-passing, and protection filter bag of dust collector and other critical components are avoided destroying.
A very big defective of underneath type bypass is: when compressed air gas source supply gas pressure instability (under the extreme case, bleed pressure be reduced to zero), internal bypass can't be opened (also of no avail even PLC provides signal instruction).Simultaneously, because the decline of bleed pressure causes the off-line cylinder can't support the weight of off-line valve plate, the off-line valve plate falls, and covers the off-line mouth.At this moment, the deduster inlet and outlet is all shut, but blower fan is still in operation, and the consequence that directly causes is: wind pipe negative pressure absolute value increases rapidly, and the blower fan stall if pipeline strength design is not enough, pipeline and deduster body part structure might takes place step on sunken; At the air intake oral-lateral, the intake stack absolute value reduces rapidly, even malleation occurs, and the result makes the boiler can't operate as normal, even the phenomenon that the boiler explosion proof door is blown takes place.This phenomenon took place in actual motion, and was quite dangerous!
The utility model content
The utility model technical issues that need to address just are to overcome the defective that existing deduster internal bypass adopts the underneath type structure, provide a kind of deduster internal bypass to protect structure automatically, and it adopts the overhead by-pass structure, has realized the automatic protection functions of internal bypass.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of deduster internal bypass of the utility model is protected structure automatically; comprise the bypass cylinder; described bypass cylinder is arranged on the deduster upper box; bypass cylinder rod bottom connects the bypass valve plate; internal bypass soft seal bar is installed, described internal bypass soft seal bar sealing internal bypass mouth on the described bypass valve plate.
On the described bypass cylinder rod bypass counterweight is installed.
The beneficial effect of the technical scheme that the utility model provides is:
The utility model adopts the overhead by-pass structure, that is, the bypass cylinder is arranged on the upper box, and under the situation of compressed air gas source pressure stability, the bypass cylinder drives the bypass valve plate and holds out against the internal bypass mouth all the time.In the time of in bleed pressure drops to certain limit, when the lifting force that the off-line valve plate overcomes the off-line cylinder will fall, the bypass valve plate is under the effect of bypass counterweight, open internal bypass mouth (about 10s clock) in advance, at this moment, the bypass valve plate falls rapidly, and a large amount of flue gases directly enter the air-out passage through the internal bypass mouth.This has just realized the automatic protection functions of internal bypass.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1; a kind of deduster internal bypass of the utility model is protected structure automatically; comprise bypass cylinder 1; described bypass cylinder is arranged on the deduster upper box 2; bypass cylinder rod bottom connects bypass valve plate 3; internal bypass soft seal bar 4 is installed, described internal bypass soft seal bar sealing internal bypass mouth 5 on the described bypass valve plate.On the described bypass cylinder rod bypass counterweight 6 is installed.
The utility model adopts the overhead by-pass structure, that is, the bypass cylinder is arranged on the upper box, and under the situation of compressed air gas source pressure stability, the bypass cylinder drives the bypass valve plate and holds out against the internal bypass mouth all the time.In the time of in bleed pressure drops to certain limit, when the lifting force that the off-line valve plate overcomes the off-line cylinder will fall, the bypass valve plate is under the effect of bypass counterweight, open internal bypass mouth (about 10s clock) in advance, at this moment, the bypass valve plate falls rapidly, and (dotted line position as shown in Figure 1) a large amount of flue gases directly enter the air-out passage through the internal bypass mouth.This has just realized the automatic protection functions of internal bypass.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1, a kind of deduster internal bypass is protected structure automatically; comprise the bypass cylinder; it is characterized in that: described bypass cylinder is arranged on the deduster upper box; bypass cylinder rod bottom connects the bypass valve plate; internal bypass soft seal bar is installed, described internal bypass soft seal bar sealing internal bypass mouth on the described bypass valve plate.
2, deduster internal bypass as claimed in claim 1 is protected structure automatically, it is characterized in that: on the described bypass cylinder rod bypass counterweight is installed.
