Abstract
The utility model discloses a kind of emergency automatic medicine adding apparatus of the cold outer cold water of Converter Station Valve based on time control, including time controller, dosing pump, medicine storing drum and chemical feed pipe.Wherein the contact closure of time controller when, dosing pump startup pumps the medicament in medicine storing drum into the cold outer cold water of Converter Station Valve by chemical feed pipe；When the contact of time controller disconnects, dosing pump is stopped.Due to can timing in outer cold water delivering medicament, without monitoring water quality in real time, eliminate water quality monitor, simplify structure, reduce cost, be more suitable for Emergency use.
Description
Technical field
The utility model is related to technical field of electric power, and in particular to a kind of cold outer cold water of Converter Station Valve based on time control
Emergency automatic medicine adding apparatus.
Background technology
In the cold outer cold water circulating system of Converter Station Valve, due to the evaporation of water, various inorganic ions and organic substance it is dense
Contracting, largely the factors such as growth can lead to the snakelike pipe outer wall of heat exchange, outer cold water pipe encrustation, equipment corrosion, pipeline to microorganism
The problems such as blocking, inner cold water temperature increases.
To prevent the appearance of the above situation, a set of special external cold water is generally had in Converter Station Valve cooling system preliminary design
Water quality carries out the automatic device of Adding medicine control.But also some times of building a station, configuration was not outer cold for Converter Station Valve cooling system earlier
The outer cold water chemicals dosing plant of water chemistry processing unit or some websites damage, the short time be difficult to repair or it is existing plus
Medicine device cannot match the chemical agent of update.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of Converter Station Valves based on time control
The emergency automatic medicine adding apparatus of cold outer cold water is simplified and is improved to existing chemicals dosing plant, in case emergent need.
To achieve these goals, the technical scheme adopted by the utility model is that：
The emergency automatic medicine adding apparatus of the cold outer cold water of a kind of Converter Station Valve based on time control, including time control
Device, dosing pump, medicine storing drum and chemical feed pipe；
During the contact closure of time controller, dosing pump startup pumps the medicament in medicine storing drum to the change of current by water pipe
In the cold outer cold water of valve of standing；When the contact of time controller disconnects, dosing pump is stopped.
The emergency of Converter Station Valve cold outer cold water of the another kind based on time control provided by the utility model adds automatically
Medicine device, periodically the delivering medicament in outer cold water, without monitoring water quality in real time, eliminates water quality monitor, simplifies structure, drop
Low cost, is more suitable for Emergency use.
Description of the drawings
Fig. 1 is the knot of the emergency automatic medicine adding apparatus of the cold outer cold water of Converter Station Valve of the utility model based on time control
Structure schematic diagram.
Specific embodiment
Further the utility model is explained with reference to specific embodiment.
The emergency automatic medicine adding apparatus of the cold outer cold water of Converter Station Valve based on time control of this programme, as shown in Figure 1,
Including time controller, dosing pump, medicine storing drum and chemical feed pipe (or pvc pipe).Time controller connects dosing pump, dosing pump connection
Medicine storing drum, the water outlet connection chemical feed pipe of medicine storing drum, chemical feed pipe lead to outer cold water pond.
By the artificial monitoring to water quality index, the administration timing of drug and dosage of rule are calculated, it (can by time controller
Adjust) the real-time keying of control metering pump, dosing is controlled with this, it is final to control water quality in claimed range.Work as time controller
When normally-closed contact disconnects, system is automatically stopped dosing, the system Automatic Dosing when time controller normally opened contact is closed.If any work
Making exception has autoalarm.
Medicine storing drum liquid level visual alarm in a low voice can also be configured as needed, convenient for control medicine system explosive barrel medicament
Surplus, when explosive barrel medicament is in low liquid level, device context sends out sound-light alarm as prompting.
This programme advantage is low cost, and pipeline is laid with simply, without detecting instrument, controls simply, installation is quick, suitable to answer
It is anxious to use.Shortcoming is to determine dosage after needing manually periodically to analyze sampling of water quality.
Above-listed detailed description is illustrating for the utility model possible embodiments, which is not to limit
The scope of the claims of the utility model, all equivalence enforcements or change without departing from carried out by the utility model are intended to be limited solely by this case
In the scope of the claims.
Claims (2)
1. a kind of emergency automatic medicine adding apparatus of the cold outer cold water of Converter Station Valve based on time control, which is characterized in that
Including time controller, dosing pump, medicine storing drum and chemical feed pipe；
