Fully automatic integrated dosing device

1、 Overview of the process of fully automatic integrated dosing device

The fully automatic integrated dosing device mainly includes four parts: drug dispensing system, metering and dosing system, safety system and environmental control system.

Solid drugs are added to the dissolving tank, and then mixed with industrial water in proportion to dissolve. They are then added to the dosing point through a metering system. The dosing control can be done manually. It can also be controlled according to the control signal output by the floating charge meter or the upper system, and automatically added

2、 Advantages of fully automatic integrated dosing device technology

Stable water quality treatment effect: Due to the need for various experimental screening of the added agents to determine the agent configuration plan and concentration, the water treatment agents are configured according to the water quality of the system, and the treatment specific effect is stable. Quick effectiveness of water treatment: With the operation of the system and the injection of chemical agents, the water treatment agents quickly diffuse and evenly distribute in the water. Wide range of applications and applicability: Chemical water treatment for circulating water can effectively treat circulating cooling water in various fields as long as the drug concentration of the system is ensured. High concentration multiple operation: The selection of reagents can be adjusted and configured reasonably according to the operating requirements of the system concentration multiple, solving the limitations of low concentration multiple operation conditions in physical methods.

3、 Application scope of fully automatic integrated dosing device:

Boiler injection of chemical solution is mainly used in situations where boilers are used in thermal power plants, chemical industry, metallurgy, ships, centralized heating, etc. Used for pre-treatment and dosing of tap water supply, mainly used in urban water plants, large enterprise owned water plants, textile printing and dyeing, steel, papermaking and other industries. Dosing in wastewater and sewage treatment in environmental protection is mainly used for wastewater and sewage treatment in cities, industrial and mining enterprises, large hotels, and restaurants.

4、 The main applications of the fully automatic integrated dosing device are:

1. Dosing in power plant furnaces: ammonia addition to feedwater, hydrazine addition, phosphate addition to boiler water, coordinated control of phosphate addition to boiler water, ammonia addition to condensate water, etc.

2. Dosing outside the power plant: adding coagulants to raw water, adding coagulants to raw water, adding stabilizers (corrosion inhibitors) to circulating water, adding scale inhibitors to circulating water, adding bactericides to circulating water, adding ammonia to the start-up boiler room, adding phosphate to the start-up boiler room, and coating the condenser with ferrous sulfate.

3. Water treatment dosing: adding coagulants, coagulants, defoamers, etc. to sewage.

5、 Process principle of fully automatic integrated dosing device

Natural water bodies contain a certain amount of colloidal particles, which can overcome the influence of gravity and maintain dynamic equilibrium under the action of electrostatic repulsion and Brownian motion, and will not condense or precipitate, thereby affecting the turbidity index of water. The commonly used method for removing colloidal particles is to add highly charged ions or polymer substances to the water body, and use principles such as electrical neutralization, adsorption bridging, and net capture to destabilize, coagulate, precipitate, and clarify the water quality. Common coagulants (coagulants) include aluminum salts, iron salts, and corresponding polymers.
