Abstract

The invention discloses a fully-enclosed condensed water recovery process and system thereof. The process comprises lifting the condensed water to a pressure water collation tank through a vacuum water returning device, then lifting to a high-level deaerator through a spray pressurizing device, delivering the condenser water and softened water in the deaerator together to a boiler through a boiler feed pump to finish fully-enclosed condensed water recovery. The invention has the advantages of advanced process, reasonable system structure, remarkably improved boiler utilization rate, reduced cost, and environmental friendliness.

Description

Condensed water totally-enclosed reclamation process and system thereof
Affiliated technical field
The present invention relates to the improvement of a kind of condensate water totally-enclosed reclamation process and system thereof, it mainly is applicable to the recycling of boiler condensate water.
Technical background
Adopt traditional open type recovery system that the condensate tank steam drain is directly communicated with atmosphere, can produce a large amount of secondary flash steams, also have a large amount of discharge of steam in atmosphere, produce thermal pollution, originally the condensate water of deoxygenation dissolved oxygen once more shortens service life of water tank.There are many correlation technique improvement projects to be suggested for this reason, for example, comprise the boiler initial steam is flowed to gas utilization unit about proposing its technology in " a kind of closed water recovery process and device therefor thereof of condensing " for Chinese patent CN99122073.0 number, form condensate water after discharging the latent heat of vaporization, this condensate water is collected in the water tank by closed Condensate recovery device, returning boiler through pump again continues to use, the used equipment of this technology comprises drain valve, pump, water treatment facilities, low level, heating power deaerator, the Industrial Control Computer that automation detects is characterized in that also comprising Condensate recovery device and condensate water and softening water transport orchestration.The closed water recovery process that condenses of the present invention is that Condensate recovery device is contained between gas utilization unit and the boiler, makes whole heat supply network form a closed circuit circulatory system, and is further perfect but its Processes and apparatus awaits.
Summary of the invention
Task of the present invention is that a kind of condensate water totally-enclosed reclamation process and system thereof will be provided, it has solved the secondary flash distillation that condensate water causes when the drain valve draining, steam water two phase flow and the condensate water of condensate water in collection conduit is resolved to the cavitation erosion problem of carrying water pump, the heat energy utilization rate of boiler greatly improves, reduce production costs, improve working environment.
Task of the present invention is real to be finished as follows.The totally-enclosed recovery system of this condensate water is used multiple gas utilization unit, the negative pressure water recovery apparatus, the pressure water collect tank, high-order oxygen-eliminating devices etc. are formed a totally enclosed recovery system, its technology is by the negative pressure water recovery apparatus, condensate water in the condensate water collection conduits is promoted to the pressure water collector, by spraying supercharging device condensate water is transported in the high-order oxygen-eliminating device then, meanwhile enter softened water tank behind the running water process soft water treatment exchanger, boiler feed pump is transported to boiler together with the condensate water and the demineralized water of oxygen-eliminating device, finishes the totally-enclosed recovery of condensate water.

The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is a condensate water totally-enclosed reclamation process sketch of the present invention.
Fig. 2 is the totally-enclosed recovery system structure chart of condensate water of the present invention.
Among the figure 1, the high pressure gas utilization unit, 2., middle pressure gas utilization unit, 3, input port, 4, the negative pressure water recovery apparatus, 5, the pressure water collect tank, 6, spray supercharging device, 7, output port.
Concrete implementation content
As can be seen from Figure 1, the technological process of the totally-enclosed recovery system of this condensate water is:
This system's adopting process is by the negative pressure water recovery apparatus, condensate water in the condensate water collection conduits is promoted to the pressure water collect tank, by spraying supercharging device condensate water is transported to high-order oxygen-eliminating device then,, finish the sealing of condensate water and reclaim after boiler feed pump is delivered to boiler together with the condensate water and the demineralized water of oxygen-eliminating device.
In Fig. 2, the totally-enclosed recovery system of this condensate water is mainly by multiple gas utilization unit, negative pressure water recovery apparatus (4), pressure water collect tank (5), spray supercharging device (6) and hydrophobic pipe network, the hot water conveying pipe, high-order oxygen-eliminating device is formed, an input port (3) of high pressure gas utilization unit (1) joins with jet chimney, and the hydrophobic pipe network of middle pressure gas utilization unit (2) is communicated with negative pressure water recovery apparatus (4), pressure water collect tank (5) one ends are connected with negative pressure water recovery apparatus (4), and its output then connects an injection supercharging device (6), and output port (7) is connected to high-order oxygen-eliminating device.High pressure gas utilization unit (1) and middle pressure gas utilization unit (2) are accepted from the next steam of boiler steam pipe by input port (3) like this, hydrophobic pipe network rises to pressure water collect tank (5) to the condensate water of collecting by negative pressure water recovery apparatus (4), spray supercharging device (6) then condensate water is delivered to high-order oxygen-eliminating device by output port (7), and running water enters Softening box after handling through the exchange of demineralized water treatment exchanger, boiler feed pump is transported to boiler together with condensate water in the high-order oxygen-eliminating device and demineralized water, thereby has finished the totally-enclosed recovery of condensate water.The compact conformation of the totally-enclosed recovery system of this condensate water, reasonable in design, the heat energy utilization rate of boiler is improved greatly, energy consumption and cost reduce.
