Application of dosing device

The dosing device is a complete set of equipment that integrates dosing, stirring, liquid transportation, and automatic control. It is widely used in power plants' raw water, boiler high-pressure feedwater, circulating cooling water, oilfield surface gathering and dehydration treatment systems, various dosing systems in the petrochemical industry, and wastewater treatment systems. Such as adding coagulants, phosphates, ammonia solution, lime water, water quality stabilizers (corrosion inhibitors), scale inhibitors, liquid insecticides, etc. 2、 The working structure principle of the dosing device mainly consists of a solution tank, a mixing tank, a mixer, a storage tank, a metering pump, a liquid level gauge, an electric control cabinet, pipelines, valves, safety valves, check valves, pressure gauges, filters, bases, escalators, etc. (can be configured according to actual user requirements). The dosing device is prepared in the mixing tank according to the required concentration of the drug, and after being stirred evenly by the mixer, it is put into the solution tank. The prepared solution is then transported to the dosing point or designated system using a metering pump (dosing pump). The complete dosing device has the characteristics of compact structure, simple safety, and easy operation and use. The device can also be designed and configured with necessary components according to the requirements of different process flows of users, achieving functional suitability (such as automatic remote control) and economic practicality.

2、 Equipment performance characteristics

a) Fully automatic operation, constant drug concentration, accurate dosing and measurement. b) The device has a sophisticated structure, occupies a small area, and is easy to install and debug. c) The equipment is equipped with advanced imported components, which have a long service life. d) The equipment tank body is made of corrosion-resistant and high-quality materials, which are beautiful and durable. e) The control system is advanced, and the equipment operates continuously, smoothly, and safely.

3、 Selection precautions

1. When users choose a dosing device, they first determine the specifications based on the amount of solution needed by the system (including metering pump parameters, mixing tank volume, solution tank volume, and on-site conditions), and then determine the dosing method based on the dosing situation (usually using the "one on, one backup" method)

2. Select the materials of each component of the dosing device (stainless steel, carbon steel, non-metallic materials, fiberglass), the model of the metering pump (diaphragm pump, plunger pump) as needed, or provide our company with the parameters of the dosing agent (name, concentration, temperature, density, viscosity, corrosiveness, etc.)

3. Users have special requirements for the dosing device based on the design process flow.
