Chemical dosing device

详情

Working principle
The system metering and dosing is achieved by the mechanical pulse action and stroke control principle of a metering pump. By the following two modes of control, automatic dosing is realized.
 
Time Control mode:
Use the time control switch of microcomputer to control the timing opening and closing of the metering pump and blow off valve, achieving dosing and blow-off at
 
Indicator Control mode:
Using changes in water quality indicators to control real-time opening and closing of the metering pump and blow off valve, achieving automatic dosing and blow-off.
 
Product features
 Automatic dosing - uniform and accurate measurement:
 Automatic blow-off - effective control of the concentration factor;
 Online monitoring - intuitively reflecting water quality trend;
 Remote monitoring - easy to implement centralized management;
 Needless to human intervention - avoiding manmade lag.
 
Scope of application
Central air conditioning and circulating cooling water system:
Industrial (open or closed) cooling water system;
Circulating water system of power plants and power stations;
Circulating water system of warships, ships and vehicles;
Circulating water system of oil fields and coal exploration platforms;
Circulating water system of coastal industries and fisheries.
 
Solutions for the circulating water system from France are:
Mexel***1 cooling water system treatment program;
Mexel***1 closed chilled water system treatment program
Mexel***1 friction control treatment program
 
The substance of innovative R & D
Mexel treatment program replaces [treating the surface] with [changing water quality];
• The fundamental difference between Mexel treatment program and traditional water treatment is that Mexel is not a water treatment agent but a (system processing agent].
Its characteristics are:
It is insoluble in water but can be dispersed in water. During treatment, it will form(a composite membrane of disperse polar molecules) on the surface of the system and ‘water is only a means of transport for transporting MEXEL to the system surface so as to achieve the treatment effect.
 
 
Characteristics of chemicals
(1) Mexel with a dispersible membrane treatment formulation can be attached to the surface of the system to form to an uninterrupted disperse - polarized molecules - bilayer functional membrane:
(2) Mobility - composite membrane is able to prevent the formation of incrustation deposition mechanism and Mexel with its powerful dispersing polarization properties is able to remove the existing incrustation step by step;
(3) Mexel not only can inhibit surface corrosion of the system, but also can prevent the pining and other common corrosion caused by chloride ions; (4) The characteristics of membrane treatment can solve the problems of organism blockage and attachment and also can drop attached organism and mucosa membrane;
(5) *9.7 % of ingredients of Mexel product are taken from the natural product, so it can be discharged directly.
 
Functions and Benefits
To provide effective protection from freshwater/seawater corrosion; To prevent the incrustation of the condenser and the heat exchanger; To inhibit the formation of organisms and the attachment of biological membrane;
To gradually remove the blockage caused by organic and inorganic corrosion within the system;
Supplementary water does not need a chemical pre-treatment; Applicable to freshwater, seawater and recycled wastewater and a higher concentration factor is allowable;
Applicable to steel, iron, alloy, plastic, cement, timber and other materials; compatible with a variety of water treatment chemicals; Saving power and water and no wastewater retreatment burden; Be environmental friendly and quickly and completely biodegradable.
