Abstract
The utility model discloses a buffering structure of a tube-type heat exchanger. The buffering structure of the tube-type heat exchanger comprises a shell body. A swell is arranged on the shell body in a protruding mode. A steam inlet is formed in one side of the swell. A straight pipe connected with the shell body is arranged on the inner side of the swell. An air inlet at the upper end of the straight pipe is higher than the steam inlet. The upper end of the straight pipe is connected with the swell through tie pieces. The lower end of the straight pipe is connected with the shell body into a whole in a welded mode. A plurality of water condensation holes are formed at the lower end of the straight pipe. According to the buffering structure of the tube-type heat exchanger, impacting force on a heat exchange pipe bundle by steam can be reduced, meanwhile the swell has the function of an expansion joint, and therefore the service life of the heat exchanger is prolonged.
Description
Technical field
The utility model relates to a kind of tubular heat exchanger, is specifically related to the buffer structure of tubular heat exchanger.
Background technology
The steam-heated heat exchange mode of the employing that has in the tubular heat exchanger; when entering shell side, steam has bigger impulsive force; in order to protect heat exchanger tube; many times all be to add impingement baffle; but increase impingement baffle and cause many difficulties tube bank is installed; when steam inlet was bigger, the erosion control effect was unsatisfactory.Therefore, the inventor envisions a kind of novel buffer structure of design, so that Steam Heating is more even, prolongs the service life of heat exchanger tube.
The utility model content
The purpose of this utility model is to provide a kind of buffer structure that uses on tubular heat exchanger, this buffer structure modern design makes Steam Heating comparatively even, and buffering effect is more excellent.
The utility model to achieve these goals, the technical solution of employing is:
The buffer structure of tubular heat exchanger, comprise housing, be raised with bulge on the described housing, one side of bulge is provided with steam inlet, the inboard of described bulge is provided with the straight tube that joins with housing, straight tube upper end air inlet is higher than steam inlet, and the upper end of straight tube is connected with bulge by lacing wire, and the lower end and the housing of straight tube are integrally welded.
Preferably, the lower end of described straight tube has a plurality of condensations water hole.
The beneficial effects of the utility model:
This kind buffer structure, on housing, increase the bulge of a projection, straight tube that joins with housing of inner increase, straight tube upper end air inlet is higher than steam inlet, the upper end of straight tube is connected with bulge by lacing wire, to strengthen the ability that straight tube bears steam impringement, have a plurality of condensations water hole in the lower end of straight tube, discharge to make things convenient for condensed water.This kind buffer structure can reduce the impulsive force that the steam heat exchanging is restrained, and bulge simultaneously can be played the effect of expansion joint, increases the service life of equipment.
Description of drawings
Fig. 1 is the structural representation of the buffer structure of tubular heat exchanger.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1, the buffer structure of tubular heat exchanger comprises housing 1, is raised with bulge 2 on the described housing 1, and a side of bulge 2 is provided with steam inlet 3, is connected with air inlet pipe 4 on the steam inlet 3, and air inlet pipe 4 is fixing by ring flange 5.The inboard of described bulge 2 is provided with the straight tube 6 that joins with housing 1, straight tube 6 upper end air inlets are higher than steam inlet 3, the upper end of straight tube 6 is connected with bulge 2 by lacing wire 7, and the lower end of straight tube 6 and housing 1 are integrally welded, has a plurality of condensations water hole 8 in the lower end of straight tube 6.
This kind buffer structure, on housing, increase the bulge of a projection, straight tube that joins with housing of inner increase, straight tube upper end air inlet is higher than steam inlet, the upper end of straight tube is connected with bulge by lacing wire, to strengthen the ability that straight tube bears steam impringement, have a plurality of condensations water hole in the lower end of straight tube, discharge to make things convenient for condensed water.This kind buffer structure can reduce the impulsive force that the steam heat exchanging is restrained, and bulge simultaneously can be played the effect of expansion joint, increases the service life of equipment.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
Claims (2)
1. the buffer structure of tubular heat exchanger, it is characterized in that, comprise housing, be raised with bulge on the described housing, one side of bulge is provided with steam inlet, and the inboard of described bulge is provided with the straight tube that joins with housing, and straight tube upper end air inlet is higher than steam inlet, the upper end of straight tube is connected with bulge by lacing wire, and the lower end and the housing of straight tube are integrally welded.
2. the buffer structure of tubular heat exchanger according to claim 1 is characterized in that, the lower end of described straight tube has a plurality of condensations water hole.
