Abstract
A kind of deflection plate used on corrugated tube heat exchanger, comprise deflection plate, deflection plate is provided with multiple through hole, protective jacket is connected with at through hole internal fixtion, described protective jacket is tubular, introducing port is provided with at the two ends of protective jacket, and on the outer wall of protective jacket, be also provided with a breach, the utility model provides a kind of deflection plate used on corrugated tube heat exchanger, the problem such as play, vibration that bellows causes due to excesssive gap at deflection plate place can be reduced, reduce the wearing and tearing of bellows, extend the service life of bellows, improve the equipment cycle of operation.
Description
Technical field
The utility model relates to the deflection plate that heat-exchange apparatus uses, particularly a kind of deflection plate used on corrugated tube heat exchanger.
Background technology
The research and development of China's corrugated tube heat exchanger from the eighties.For over ten years, have developed diversified corrugated tube heat exchanger (as shown in Figure 5), and achieve good benefit in practice, compared with common tubular heat exchanger, this technology is improved obviously in raising heat exchange efficiency and reduction system pressure etc., and tube side not easily blocks up, and maintenance is convenient, take up an area little, be widely used in solution-air, liquid-liquid heat exchange occasion.
The bellows of corrugated tube heat exchanger in process of production, due to the particularity of technique, can not ensure that the crest often propping up pipe is at same position (as shown in Figure 6), therefore once deflection plate is in wave trough position, then the gap of this place's pipe and deflection plate is larger, easy induced vibration, thus cause pipe fatigue wear to be broken.Deflection plate fails bellows is effectively supported, thus makes pipe amount of deflection herein larger.In gas liquid exchanger, under the impact of shell side inlet gas, long pipe span easily produces pipe high vibration.Dither causes Metal Material Fatigue, thus causes the intensity of stainless steel wave grain material and toughness to disappear.And then pipe is cracked or makes pipe original crack Rapid Expansion, ultimate failure.Destruction place be everlasting pipe cross long span place.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of deflection plate used on corrugated tube heat exchanger, the problem such as play, vibration that bellows causes due to excesssive gap at deflection plate place can be reduced, reduce the wearing and tearing of bellows, extend the service life of bellows, improve the equipment cycle of operation.
In order to solve the problem, technical solutions of the utility model are: a kind of deflection plate used on corrugated tube heat exchanger, comprise deflection plate, deflection plate is provided with multiple through hole, protective jacket is connected with at through hole internal fixtion, described protective jacket is tubular, is provided with introducing port at the two ends of protective jacket, and on the outer wall of protective jacket, be also provided with a breach.
Further, described protective jacket adopts the mode of local welding to be fixedly connected in through hole, and the solder joint on protective jacket outer wall is positioned on the position away from breach.
Further, described introducing port is expand outwardly tubaeform.
The technique effect after this structure is adopted to be: bellows, in the process of swollen system, in the position of heat exchanger traverse baffle, places a protective jacket in advance.Two, left and right crest tightly blocks by protective jacket, make it can not play, reduce vibration and the wearing and tearing of bellows, extend the service life of bellows, the raising equipment cycle of operation, the oscillation phenomenon because of the larger generation in gap when bellows trough is in Lourver position can be efficiently solved.
And the horn mouth of the breach be provided with on protective jacket for expanding and convenient plug, and then bellows can not be affected in installation poling process, under the elastic force effect of protective jacket self, make to be inserted into bellows in protective jacket by protective jacket firm grip; Solder joint on protective jacket is positioned at the position away from breach, is because solder joint is positioned at the expansion that this position can not affect breach.

Detailed description of the invention
As shown in Fig. 1 to 4, a kind of deflection plate used on corrugated tube heat exchanger, comprise deflection plate 1, deflection plate 1 is provided with multiple through hole 11, protective jacket 2 is connected with at through hole 11 internal fixtion, described protective jacket 2 is tubular, is provided with introducing port 21 at the two ends of protective jacket 2, and is also provided with a breach 22 on the outer wall of protective jacket 2.
Further, described protective jacket 2 adopts the mode of local welding to be fixedly connected in through hole 11, and the solder joint 23 on protective jacket 2 outer wall is positioned on the position away from breach 22.
Further, described introducing port 21 is tubaeform for what expand outwardly.
Bellows 3, in the process of swollen system, in the position of heat exchanger traverse baffle 1, places a protective jacket 2 in advance.Two, left and right crest tightly blocks by protective jacket 2, make it can not play, reduce vibration and the wearing and tearing of bellows 3, extend the service life of bellows 3, the raising equipment cycle of operation, the oscillation phenomenon because of the larger generation in gap when bellows 3 trough is in deflection plate 1 position can be efficiently solved.
And the horn mouth of the breach 22 be provided with on protective jacket 2 for expanding and convenient plug, and then bellows 3 can not be affected in installation poling process, under the elastic force effect of protective jacket 2 self, make to be inserted into bellows 3 in protective jacket 2 by protective jacket 2 firm grip; Solder joint 23 on protective jacket 2 is positioned at the position away from breach 22, is because solder joint 23 is positioned at the expansion that this position can not affect breach 22.
