Description
Technical field
The utility model relates to color-coating line waste heat utilization equipment, especially a kind of easy cleaned color-coating line cigarette water heat exchange
Device.
Background technique
Cigarette water- to-water heat exchanger is mainly used in the burned waste gas system of color-coating line, is used for VOC (volatile organic matter matter)
The heat that waste gas burning generates is recycled, and is provided heat source to pre-processing device, is reached energy-saving and environment-friendly requirement.Currently on the market
There are many structure type of cigarette water- to-water heat exchanger, and various heat exchanger structures are similar.Namely flue gas is walked outside pipe, water is walked in pipe, is led to
Cross heat exchange method heat cycles water.But from the point of view of the knowhow of many years, the heat exchanger tube inside heat exchanger is easy to block,
Because what is walked in pipe is lye or hot water, long-play forms very thick alkali dirt on inside pipe wall.Heat exchanger area is caused to become
It is small, it is more serious to lead to the blockage that exchanges heat, it causes water temperature low, seriously affects production.In addition, due to the heat exchange of traditional heat exchanger
Pipe is welded to inside, can not be cleared up at all, and typically by the way of weak base cleaning, but this cleaning way is not
The alkali dirt in heat exchanger tube can thoroughly be cleaned up.
Utility model content
To solve the above problems existing in the prior art, the utility model designs one kind and can preferably clear up in heat exchanger tube
The easy cleaned color-coating line cigarette water- to-water heat exchanger of alkali dirt.
To achieve the goals above, the technical solution of the utility model is as follows: a kind of easy cleaned color-coating line cigarette water changes
Hot device, including shell, exhaust gases passes and aquaporin, the aquaporin include inlet attack, ponding short tube, heat exchanger tube and outlet
Connector；The shell is mounted on bottom plate, on the basis of the bottom plate is mounted on by bracket；The heat exchanger tube is mounted on
It holds on card, both ends are connect with ponding short tube respectively；The outer end of the ponding short tube is connect with rectangular flange, the rectangle
The outside of flange and rectangular flange lid are tightly connected.
Further, it is sealed between the rectangular flange and rectangular flange lid with asbestos rubber pad, passes through high-strength bolt
Fastening.
Further, the asbestos rubber mat thickness be 5 ± 1mm, 450 ± 10 DEG C of heatproof.
Further, the heat exchanger tube is 304 stainless-steel seamless pipes.
Further, rectangle groove is set on the inside of the rectangular flange lid.
Further, handle is arranged in the rectangular flange outer side of lid.
Compared with prior art, the utility model has the following beneficial effects:
If 1, exchanging heat blockage, the utility model can be laid down the rectangular flange lid at the heat exchanger both ends of blocking, very
Intuitively see that the stopping state inside heat exchanger tube can be cleared up manually using tool, it is ensured that heat exchanger if plugged
It is unimpeded.
2, the rectangular flange lid of the utility model is formed using lathe process, thickness 30mm, it is ensured that rectangular flange lid
Expanded by heating is indeformable, and asbestos rubber pad is pressed in flange groove.
3, the utility model solves the problems, such as that heat exchange blockage can not be handled, and the heat exchanger of this structure design can be throughout the year anti-
It is multiple to use, will not due to tube blockage integral replacing.
4, the utility model substantially prolongs the service life of heat exchanger, reduces business equipment input cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the rectangular flange lid of the utility model.
In figure: 1, bracket, 2, bottom plate, 3, ponding short tube, 4, asbestos rubber pad, 5, rectangular flange, 6, rectangular flange lid, 7,
Heat exchanger tube, 8, end card.
Specific embodiment
The utility model is further described through with reference to the accompanying drawing.As shown in Figs. 1-2, a kind of easy cleaned coloured silk
Apply line cigarette water- to-water heat exchanger, including shell, exhaust gases passes and aquaporin, the aquaporin include inlet attack, ponding short tube 3,
Heat exchanger tube 7 and outlet connection；The shell is installed on a base plate 2, on the basis of the bottom plate 2 is mounted on by bracket 1；Institute
The heat exchanger tube 7 stated is mounted on the card 8 of end, both ends are connect with ponding short tube 3 respectively；The outer end of the ponding short tube 3 and square
Shape flange 5 connects, and the outside of the rectangular flange 5 and rectangular flange lid 6 are tightly connected.
Further, it is sealed between the rectangular flange 5 and rectangular flange lid 6 with asbestos rubber pad 4, passes through high-strength spiral shell
Bolt fastening.
Further, the asbestos rubber pad 4 is with a thickness of 5 ± 1mm, and 450 ± 10 DEG C of heatproof.
Further, the heat exchanger tube 7 is 304 stainless-steel seamless pipes.
Further, rectangle groove is set on the inside of the rectangular flange lid 6.
Further, handle is set on the outside of the rectangular flange lid 6.
Specific embodiment of the present utility model is as follows:
Heat exchanger tube 7 is 304 stainless-steel seamless pipes, length of straight pipe about 3032mm, and heatproof reaches 500 DEG C, and water walks in pipe, cigarette
It makes leave with rage and exchanges heat outside pipe.7 both ends of heat exchanger tube are fixed on the card 8 of end, and sealing welding is not allowed using dye penetration inspection
Leak.
Rectangular flange 5 is arranged in 7 both ends sealing welding ponding short tube 3 of heat exchanger tube, 3 outer end of ponding short tube, and ponding short tube 3 is
304 stainless steel materials, thickness 8mm, with end 8 sealing welding of card.
It is sealed between rectangular flange 5 and rectangular flange lid 6 with asbestos rubber pad 4, flange is fastened with the high-strength bolt of M20.
Asbestos rubber pad 4 thickness 5mm, 450 DEG C of heatproof.
