Description
Technical field
The utility model relates to a kind of condensate water recovery device, relates in particular to the condensate water recovery device that a kind of conveyance conduit is positioned at underground vapour system.
Background technology
The vapour system that general band condensed water reclaims function mainly comprises the boiler that steam is supplied with, steam conveying pipe, and condensed water recovery channel and condensed water reclaim water collect tank.Factory for some self-produced steams and application, owing to use the remote needs of carrying in gas workshop to each from boiler, when designing in early days the dispensing of its steam be responsible for and the condensed water recovery channel some be in below ground, the condensed water recovery channel needs the lifting (as 5～8 meters) of certain altitude to reclaiming water collect tank, so there is certain back pressure (as 0.5-0.8Barg) in recovery channel.
And in the factory owing to produce and the needs of maintenance, not operation constantly always always of vapour system needs relevant gas equipment of switch and vapour system through regular meeting.In the system boot stage, system's rate of rise is slower, to guarantee certain heating coil time.At this moment, steam pressure was lower in the steam dispensing was responsible for; Exist owing to recovery channel has certain back pressure (as 0.5-0.8Barg), be full of condensed water in the condensed water recovery channel when shut down last time, can't get rid of fully, therefore, start boost phase Automatic steam trap Trap normally exhaust steam dispensing is responsible for interior condensed water.Because the temperature of the steam dispensing person in charge and condensed water recovery channel is different, the expansion length of two pipelines is also different, and the pipe joint that welding appears in the water-collecting bag place that therefore often causes the steam dispensing to be responsible for is broken; And there is water hammer to take place in the main steam header, safety in production is threatened; In addition, condensed water contains materials such as oxygen, carbon dioxide, is trapped in the pipeline pipeline is easily caused corrosion.
The factory owner will adopt following solution at present:
1. boost, utilize when shutting down the stage emptying manually to remain in the condensed water of the not emptying in the condensed water recovery channel and the steam dispensing person in charge at system boot, shortcoming is not only to waste energy and water resource, and needs labor intensive;
2. boost, utilize when shutting down the stage magnetic valve with water-collecting bag and the emptying of condensed water recovery channel be responsible at system boot, shortcoming is still to waste energy and water resource.
3. install an electrodynamic pump additional in the pipeline appropriate location condensed water in water-collecting bag and the recovery channel is directly returned the recovery water collect tank, the energy that can recycle water resource and wherein contain.But shortcoming is, because condensate temperature higher (about 100 ℃), the blade of electric pump can be subjected to cavitation hazard, shortens service life, has improved maintenance cost.
The power mechanical pump principle is different from electrodynamic pump, can not be subjected to the harm of cavitation, but has the shortcoming that flow rate is restricted.In the small steam system of some factory, because gas equipment is more single, quantity is few, highly not high, therefore introduce power mechanical pump in use sometimes, directly condensed water is recovered to water collect tank, so just can reduce the condensed water recovery channel, but problem is a dynamic power machine pumping system unit price is more than 20 times of Automatic steam trap Trap cost at least, so the factory the inside has only the just independent working power mechanical pump of visual plant basically, and only uses Automatic steam trap Trap on main steam header road and condensed water recovery line.
