Fully automatic water treatment dosing device

Shandong Zhengyuan Environmental Protection Manufacturer specializes in customizing water treatment equipment dosing devices. The main models of automatic dosing devices include dual pump single control combination, three pump dual control combination, and combined boiler water R-value automatic control devices. The prices are also different, and the structures of each type are slightly different. Next, Shandong Zhengyuan's dosing device manufacturer will explain them to you in depth.

Introduction to dosing device for water treatment equipment:

Fully automatic dosing equipment is often used in fields such as power, petroleum, chemical, metallurgical, environmental engineering, water treatment, etc. It is necessary to continuously and automatically inject a certain liquid into another liquid to form a mixture, or to cause a chemical reaction between the added agent and a certain component present in the liquid to achieve the expected process requirements. To achieve the best results, we automatically track and adjust the dosing rate of the added chemical agents under changing working conditions. Therefore, in the automatic dosing device, we adopt advanced automatic control methods to control the dosing amount.

Price of water treatment dosing device:Starting from 700 yuan, the specific price needs to be quoted based on the model.

The main features of the dosing device for water treatment equipment are:

1. The water treatment dosing device adopts intelligent instrument fully automatic control, fully automatic operation, saving labor;

2. The parts in contact with the medium are made of corrosion-resistant engineering plastics and stainless steel, which have good corrosion resistance performance;

3. Solid drugs are accurately added using a dry powder dosing machine, with precise and adjustable dosing amounts to ensure stable drug ratios;

4. Set up fault alarms in the control box, and make alarms, automatic manual switching, single machine stop, system stop and other actions according to different situations to ensure the safe operation of the equipment;

5. The entire water treatment dosing equipment adopts a three tank overflow solution operating system, which makes the equipment structure simple, small in size, and easy to install. Suitable for the process flow of dissolving and continuously adding chemicals.

6. The water treatment dosing system adopts multiple tanks to ensure thorough dispersion and maturation.

Structure of water treatment dosing device:

The fully automatic dosing device for water treatment mainly consists of an automatic control cabinet, recorder, AC motor, dosing pump, etc. There are frequency converters, regulators, detectors, etc. inside the automatic control cabinet, as shown in the table below. The selection of the detector is determined by the type of medication added by the user. For example, for ammonia addition, the detector can use a conductivity meter or a pH meter. For phosphate addition, a fast phosphate analyzer can be used. For neutralization tanks, a pH meter can be used. For coordinated phosphate treatment, an R meter is required. For coagulation, a flow current meter is used. For chlorine addition, a residual chlorine meter is required.

Principle of water treatment dosing device:

The dosing pump motor of the dosing device is driven by an AC frequency converter to inject the medicine into the liquid. The concentration of the medicine is detected by a detector, which inputs an electrical signal proportional to the concentration to the regulator and compares it with the set value to obtain a deviation signal. The regulator performs proportional and integral calculations on the deviation signal according to the process requirements, and the calculated result signal is sent to the frequency converter. The frequency converter changes the frequency of the motor's working power supply according to the adjustment signal output by the regulator, causing the motor speed to change, changing the concentration of the medicine in the injected liquid, and controlling the concentration of the medicine within the optimal range.

Application scope of water treatment dosing device:

1. Wastewater treatment: flocculation treatment of urban or industrial wastewater, treatment of sludge dewatering process, third or fourth level sewage treatment of municipal wastewater;

2. Drinking water treatment: a water treatment plant that uses surface water as a water source, and a dosing system for water purifiers and coagulants;

3. Process dosing: dosing for wastewater treatment processes in the food, beverage, and pharmaceutical industries, and dosing for wastewater treatment processes in the chemical, petroleum, and pulp and paper industries;

4. Other industries: electroplating, food and beverage industry wastewater treatment, chemical, petroleum, pulp and paper industry wastewater treatment, mineral smelting industry wastewater treatment.

Precautions for purchasing water treatment dosing devices:

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

2. Select the materials of each component of the dosing device (stainless steel, carbon steel, non-metallic materials), the model of the metering pump (diaphragm pump, plunger pump), or the metering parameters for the added medication (name, concentration, temperature, density, viscosity, corrosiveness, etc.) as needed;

3. The ordering system includes several boxes and several pumps;

4. Is the metering pump a plunger pump or a diaphragm pump;

5. Measure pump flow and pressure;

6. Is the system manually controlled or automatically controlled;

7. Other special requirements for dosing devices.
