Description

A kind of heat exchanger that can anti-blocking deslagging
Technical field
The utility model relates to a kind of heat exchanger that can anti-blocking deslagging, particularly a kind of heat exchanger that can be used for reclaiming heat energy in the papermaking draining
Background technology
In paper, generally produce paper per ton and will use about 7-10 ton water.Paper technology need be used hot water, also is hot water so waste water is discharged in papermaking, and temperature can reach more than 40 ℃.Water also need be reduced to water temperature about 35 ℃ in the anaerobic-aerobic treatment process after being discharged to the sewage-farm processing.The general method that adopts the cooling tower heat radiation looses the heat in the draining to aerial, has both wasted heat energy, has consumed power again, and also some foul smell also has been discharged in the environment.Adopting heat exchanger to reclaim heat energy can address the above problem, but since the papermaking draining to contain solid content more, general heat exchanger can stop up very soon, can't operate as normal.
Summary of the invention
The purpose of the utility model provides a kind of heat exchanger that can anti-blocking deslagging, is particularly suitable for having the heat recovery of the papermaking draining of solid content, adopts this heat exchanger can improve paper machine room water inlet water temperature, reduces the energy consumption in the technical process.
For reaching above-mentioned goal of the invention, the utility model adopts following technical scheme:
This heat exchanger that can anti-blocking deslagging; It comprises: heat exchanger main body 1; Main body is provided with dirty hot water inlet 3, outlet of sewer 4, clear water import 8 and heat-clearing water out 13, and bottom part body is provided with slagging coutrol valve 12 and sediment outlet 11, and heat exchanger top one end is established a flushing water distributor 2; The flushing water distributor is connected with the axle of being intake by the rotation of driven by motor; Rotate the swivel joint 6 that is coupling of intaking, the water under high pressure outlet of swivel joint one side joint circulating pump 9, pump inlet connects from drain filter 10 outlets.
Described flushing water distributor is fan-shaped.
The top of described flushing water distributor is provided with guide wheel 14, and this guide wheel cooperates with guide rail 15 on being located at main body inner wall.

The specific embodiment
This heat exchanger comprises: heat exchanger main body 1; Main body is provided with dirty hot water inlet 3, outlet of sewer 4, clear water import 8 and heat-clearing water out 13, and bottom part body is provided with slagging coutrol valve 12 and sediment outlet 11, and heat exchanger top one end is established a flushing water distributor 2; The flushing water distributor is connected with the axle of being intake by the rotation of driven by motor; Rotate the swivel joint 6 that is coupling of intaking, the water under high pressure outlet of swivel joint one side joint circulating pump 9, pump inlet connects from drain filter 10 outlets.
Among Fig. 2, the top of flushing water distributor is provided with guide wheel 14, and this guide wheel cooperates with guide rail 15 on being located at main body inner wall, and 16 is the tubulation of heat exchanger.
Among Fig. 3 a, Fig. 3 b, 6-7 is the shell of swivel joint, and 6-6 is the import that connects water under high pressure, and 6-8 is the inner core of swivel joint; Inner core and axle are with threaded engagement, and 6-1 is a spring collar, and 6-2 is a bearing group; 6-3 is sliding spring seat and spring, and 6-4 is the sealing rotating ring, and 6-5 is sealing Jing Quan.17 is the gear that is connected with rotation water inlet axle, and rotation water inlet axle adopts key 18 with being connected of gear 17.
The course of action of this heat exchanger is:
The papermaking thermal wastewater gets into from dirty hot water inlet 3, through tubular heat exchanger main body 1 tube side, is discharged by outlet of sewer 4.Clear water is got into by clear water import 8, through 1 tubular heat exchanger main body shell side, is discharged by clear water output 13, reaches the heat exchange purpose.
Heat exchanger top one end has a flushing water distributor 2, and the flushing water distributor is rotated by motor 5, decelerator driven gear slowly, covers the Tube Sheet of Heat Exchanger inject high pressure water of part simultaneously to quilt, washes away and is blocked in the solid content that precipitates in the pipe.
The slagging coutrol valve 12 of heat exchanger bottom and sediment outlet 11 are regularly opened and are discharged the deposition solid content.
By circulating pump 9, be connected by pipeline, form a flushing water circulatory system from drain filter 10, swivel joint 6, rotation water inlet axle and flushing distributor.Water is from heat exchanger body, and through removing the middle impurity that anhydrates from drain filter 10 (outsourcing finished product), circulating pump 9 (outsourcing finished product) improves water pressure, to the flushing water distributor, removes to wash away the pipe of heat exchanger through swivel joint.The flushing water distributor is intake with rotation and is adopted flange, bolt and pad to be connected between the axle.
From drain filter 10, the solid content that can be about to certainly filter out is discharged automatically.Swivel joint 6 (outsourcing finished product) and mechanical seal 7 (outsourcing finished product) make equipment in motion, can guarantee seal for pipe joints, do not reveal.
On the flushing water distributor outward flange guide wheel is arranged, guide wheel rolls along heat exchanger shell upper rail, resists the deboost that differential water pressures causes in the flushing water distributor, also is convenient to reduce the resistance that the flushing water distributor rotatablely moves.
