Description
Technical field
The utility model relates to a kind of water cooling plant, relates in particular to a kind of water composite cooling pipe multichannel, pre-cleaning type that is provided with.
Background technology
The industries such as the electric power of China, iron and steel, nonferrous metallurgy, building materials, chemical industry, pharmacy, casting usually can produce high-temperature dusty gas in process of production at present; because production technology is different, contain again other the pollutant such as dust, Sox, NOx, heavy metal in these high-temperature flue gas.
For these pollutants are processed, reach country to the discharge standard of different pollutants, need various treatment facilities to be removed for above pollutant.The equipment such as general employing deduster carry out the dust removal process rear emptying discharging of just carrying out up to standard to these high-temperature flue gas.But the temperature of this type high temp dust-laden gas is very high, have up to 800 ℃ about, if will be so the dusty gas of high-temperature directly carry out dust removal process, then can damage cleaner, normal production is impacted.So needing cooling before high-temperature dusty gas is carried out dedusting processes.The volume that can reduce on the one hand flue gas is processed in cooling; Can pollute the in addition removal of part in the flue gas certain according to the characteristics of smoke property and cooling system on the other hand, reduce the processing load of follow-up equipment, thereby guarantee treatment effect; Third aspect high-temperature flue gas has proposed higher requirement to the material of cooling device and the installation and repairing of equipment etc., and the production cost of enterprise is increased.
It mainly is after making high-temperature flue gas enter water cooling plant that cooling is processed, make it fully to contact with the heat-transfer surface of water cooling plant, by convection heat transfer' heat-transfer by convection with the heat in the flue gas by high-temperature flue gas to the cooling water transmission, thereby reach the purpose of cooling, then discharge by outlet through the cooled gas of water cooling plant, and cooling water reuse after circulation.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and the Multi-channel water cooling tube of a kind of good cooling results, long service life is provided, and can effectively protect follow-up cleaner safety.
In order to reach above-mentioned effect, the utility model provides a kind of pre-cleaning type water composite cooling pipe, comprise the multichannel cooling tube body that is formed by outer wall and inwall, the interior week formation exhaust gases passes of its inwall, the bottom of described exhaust gases passes is provided with a plurality of deflectors, and described deflector is inclined at exhaust gases passes inside.
Because the stopping of deflector, enter flue gas stream in the water composite cooling pipe and produce and swerve, grit wherein is because the inertia effect, thereby grit is separated with flue gas, sinks because of Action of Gravity Field again.Want large many because of the inertia force of dust than the gravity of dust, the treatment effeciency of therefore comparing expansion chamber is much higher, can trap the particle of 10um.
The preferred version of such scheme is that described deflector and horizontal direction are miter angle.
In order to improve heat exchange efficiency, be installed with heat exchange fin in the middle of described outer wall and the inwall.Because the existence of heat exchange fin, so that the heat exchange of the unit length of water cooler has increased than the heat exchange area of smooth pipe is about 20%, thereby heat transfer efficiency is higher.
In order to reduce exhaust gases passes to the on-way resistance of flue gas, the inboard of described inwall is provided with one deck smooth layer.
The turnover direction of cooling water and the turnover opposite direction of flue gas in the passage of described cooling tube.Be that water composite cooling pipe chuck interior cooling water and high-temperature flue gas carry out countercurrent flow, the driving force of heat transfer of its counter-flow heat exchange is greater than the driving force of heat transfer of the parallel type of the same period, the larger then heat transfer rate of driving force of heat transfer is faster, and this that is to say that counter-flow heat exchange is faster than the heat transfer rate of parallel type heat exchange.
In order to prevent that the grits such as heavy metal in flue gas from damaging the inwall of water composite cooling pipe and cause damage to equipment, described inwall is provided with wearing layer, and described wearing layer is positioned at the periphery of deflector.
During work, after high-temperature flue gas entered water composite cooling pipe, making it with the inwall of water composite cooling pipe was that heat-transfer surface fully contacts, and carries out heat exchange, reduced flue gas heat, reached the purpose to flue gas cool-down.Big particle in the flue gas produces by deflector and swerves simultaneously, and meeting sedimentation owing to its centrifugal inertial force effect is discharged by ash discharging hole, reaches the effect that some dust in the flue gas are removed, and has alleviated the dedusting pressure of follow-up cleaner.Through field experiment, at 12 ℃-20 ℃, and different according to the particle diameter in the high-temperature flue gas, efficiency of dust collection is about 20%-40% to high-temperature flue gas through the temperature difference behind the water composite cooling pipe of the present utility model of unit length.
So the beneficial effects of the utility model have:
1, the bottom of exhaust gases passes is provided with deflector, flue gas is produced swerve, and wherein dust granules is removed the dust of 20%-40% in the flue gas owing to centrifugal inertial force effect sedimentation is discharged, and has alleviated the dedusting pressure of follow-up cleaner.
2, owing to be installed with heat exchange fin in the middle of the outer wall of water composite cooling pipe and the inwall, increased approximately 20% so that heat exchange area without the smooth pipe of heat exchange fin is compared in the heat exchange of its unit length, thereby heat transfer efficiency is higher.
3, because the turnover direction of the interior cooling water of the passage of cooling tube and the turnover opposite direction of flue gas make cooling water and high-temperature flue gas carry out countercurrent flow, its heat transfer rate is fast, heat exchange efficiency is high.
4, because the inboard of inwall is provided with one deck smooth layer, reduce the on-way resistance to flue gas; The inwall that is positioned at the air deflector periphery is provided with wearing layer, prevents that the grits such as heavy metal in flue gas from damaging and the useful life of extension device the inwall of water composite cooling pipe, and has effectively protected the safety of follow-up cleaner.
