Description
Technical field
The present invention relates to the Ammonia adding System of power plant chemistry water system.
Background technology
To being used as therrmodynamic system working media and cold in Chemical Water Treatment System in Power Plant Thermal Power Station Water vapour images
But the water of medium has stringent water quality requirement, as high pressure boiler water supply do not require nothing more than hardness is low, and dissolved oxygen amount is atomic, solids content and
Content of organics is also atomic, be not reaching to the water of water quality standard will make power plant equipment can not safety economy operation, it is necessary to
Stringent control water water quality.
Wherein, in order to enable the pH matter of water quality reaches the set quota, it is necessary to add ammonium hydroxide to water, feedwater plus ammonium hydroxide are
System is Ammonia adding System.In the actual motion of Ammonia adding System, with the use of ammonium hydroxide in ammonium hydroxide fluid reservoir, ammonium hydroxide constantly subtracts in tank
It is few, when ammonium hydroxide is reduced to a certain extent in tank, it is necessary to supplement the higher ammonium hydroxide of new concentration to ammonium hydroxide fluid reservoir, be usually
The ammonium hydroxide of 25% concentration is dumped into inside ammonium hydroxide fluid reservoir, then is blended into water so that the ammonia concn in ammonium hydroxide fluid reservoir reaches
About 3% or so, then the ammonium hydroxide that ammonium hydroxide fluid reservoir concentration inside is about 3% is added in chemical water by the ammonification pump of Ammonia adding System and is gone,
The water of pH value qualification is made.
But in practical operation, the ammonium hydroxide of 25% concentration is dumped into inside ammonium hydroxide fluid reservoir by operating personnel, first
The bung of ammonium hydroxide packing container is opened, then directly ammonium hydroxide is dumped into inside ammonium hydroxide fluid reservoir, during toppling over, ammonia
Water can be significantly evaporate into air, and taste is difficult to hear, and long-term a large amount of suction ammonium hydroxide can cause operating personnel to be poisoned.
The content of the invention
In order to overcome the prior art since directly ammonium hydroxide is dumped into inside ammonium hydroxide fluid reservoir, during toppling over,
Ammonium hydroxide can be significantly evaporate into air, and taste is difficult to hear, and long-term a large amount of suction ammonium hydroxide can cause the deficiency of poisoning, the present invention
A kind of supply air system of Ammonia adding System is provided.
The technical solution adopted by the present invention to solve the technical problems is：Supply air system includes supply air system air inlet, height
Position air outlet, low level air outlet, gutter electric guard board, ventilating fan, the opening of the supply air system air inlet are located outside, high
The air outlet of position air outlet is higher than the tank deck of ammonium hydroxide fluid reservoir, positioned at the top of ammonium hydroxide fluid reservoir；The air outlet of low level air outlet
Top edge is highly less than the tank deck of ammonium hydroxide fluid reservoir；Ventilating fan is installed on wall higher position；Gutter electric guard board is installed on row
On the cavity that ditch is formed through wall ground, hole is completely covered in baffle.
Including supply air system air inlet, high-order air outlet, low level air outlet, gutter electric guard board, ventilating fan it is each
Covered with guard in air port.
In order to strengthen fresh air, including multiple supply air system air inlets, high-order air outlet, low level air outlet, gutter are electronic
Baffle, ventilating fan.
Observed in operation for the ease of operating personnel, high-order air outlet end is connected using hose, including air outlet is adopted
It is made of transparent material.
In general, gutter electric guard board is outwards opened.
In control method, comprising a controller, the hard contact control of generally use, when ventilating fan starts, together
When close gutter electric guard board.
The present invention operation principle be：When needing to supplement ammonium hydroxide for ammonium hydroxide liquid storage pipe, close the doors and windows, open air draft
Fan, closes gutter electric guard board, with the work of ventilating fan, room air is sucked into outdoor, forming chamber inner air pressure
The slightly less than situation of ambient atmospheric pressure, at this moment, fresh outdoor air by supply air system air inlet, high-order air outlet,
Low level air outlet, adds to interior, since high-order air outlet, low level air outlet are placed exactly in the region residing for operating personnel, makes
Obtain the miniclimate that operating personnel region forms a fresh air aggregation.Whole process is due to effectively accurate by fresh air
The region residing for operating personnel is really sent to, protects operating personnel.
The beneficial effects of the invention are as follows：The first, fresh air is effectively accurately sent to the region residing for operating personnel, protected
Operating personnel, in contrast, the air inlet of the prior art is located at window, door region, and fresh air is unfavorable away from operating personnel
In protection operating personnel.2nd, pressure differential energy saving, that the present invention is produced using ventilating fan, driving fresh air are added to from outdoor
Interior, does not increase any extra fan, has reached the dual-purpose effect of a fan, has saved the energy, in contrast, existing skill
If the fan of the separately installed supply air system of art is, it is necessary to additionally consume the energy.
