Abstract
The utility model discloses a pressured anticorrosion and anti-freezing system for an outdoor-type waste heat boiler, and the system comprises a plurality of partitioning fixed-point drainage pollution discharge collection points of a boiler and a recovering and centralizing device, wherein the partitioning fixed-point drainage pollution discharge collection points of the boiler and the recovering and centralizing device are connected with control valves by virtue of independent pipelines; the recovering and centralizing device is communicated with the water inlet end of the heating pipe of a feed water heater and is provided with the control valve; the water outlet end of the heating pipe of the feed water heater is communicated with a deaerator and a water feeding pump; and a control valve is arranged between the deaerator and a water feeding pump. According to the pressured anticorrosion and anti-freezing system for the outdoor-type waste heat boiler, the problem of a pipeline valve freezing because of improper air temperature variation regulation for drainage pollution discharge can be solved. In addition, heat loss which is released originally is secondarily utilized to heat newly-added water of the boiler to achieve an obvious energy saving effect. Then, when the boiler is in a blowing-down state, the boiler does not need to discharge water, so that the boiler is still in a pressured anticorrosion state, an overhauling and checking link for restarting the boiler by the traditional dry anticorrosion is omitted, and the operation cost is lowered.

The utility model content
The purpose of the utility model is exactly to eliminate the deficiency of above-mentioned prior art; Provide a kind of outdoor type waste heat boiler band to press anticorrosion, winterization system, it is anticorrosion to have adopted band to press, and when boiler shutdown is safeguarded, needn't discharge water; Make boiler body be in band all the time and press anticorrosion state; Highly beneficial service life to prolonged boiler, native system reclaims second use with the water that the hydrophobic blowdown of conventional boiler emits simultaneously, reduces cost.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of outdoor type waste heat boiler band is pressed anticorrosion, winterization system; Comprise several subregions of each boiler fix a point hydrophobic blowdown bleeding point with reclaim centralised arrangement; Each boiler subregion fix a point hydrophobic blowdown bleeding point with reclaim centralised arrangement and be connected through independent pipeline, the recovery centralised arrangement is communicated with feed-water heater heating tube water inlet end, feed-water heater heating tube water side connection oxygen-eliminating device and feed pump.
Preferably, said boiler subregion fixes a point to be provided with the secondary control valve between hydrophobic blowdown bleeding point and recovery centralised arrangement, reclaims between centralised arrangement and feed-water heater and is provided with the one-level control valve, is provided with the one-level control valve between oxygen-eliminating device and feed-water heater.
Preferably, said recovery centralised arrangement is selected the combination of tank container or tubulose water collector or tank container and tubulose water collector for use.
Preferably, said recovery centralised arrangement selects for use tank container and tubulose collector group fashionable, is provided with the one-level control valve between tank container and tubulose water collector.
The beneficial effect of the utility model:
That outdoor type waste heat boiler band that the utility model provides is pressed is anticorrosion, winterization system at first all is provided with bleeding point with each boiler subregion hydrophobic blowdown pipeline place that fixes a point; The water of hydrophobic blowdown place discharging is concentrated to retracting device; The unified feed-water heater that is communicated with of retracting device has not only solved hydrophobic blowdown and has regulated the improper bursting by freezing pipe valve problem that causes because of temperature Change, and the thermal losses second use that originally emits newly dropped into water to boiler heat; It is too high to have solved the recycle-water temperature; Cause the problem of water pump vaporization, improved feed temperature simultaneously, energy-saving effect significantly improves economy; Secondly when the boiler shutdown state, needn't carry out draining, make boiler be in band all the time and press anticorrosion state, reduce the maintenance inspection link when conventional dry is anticorrosion to restart boiler, cut operating costs boiler.
