What are the introduction and precautions of PAC dosing device

Dosing has always been an important link in industrial production, because the production and preparation need to use the addition reaction of materials, and it is necessary to control the time and quantity, so naturally there are related dosing equipment to ensure the efficiency and accuracy of operation, PAC dosing device is one of the more commonly used, so let's take a look at PAC dosing device How to use the PAC dosing device and what should be paid attention to.

一、 Introduction of PAC dosing device

1. Dissolving tank: put PAC polyaluminum chloride and water into the dissolving tank quantitatively, start the mixer to mix and dissolve when the medicine enters the water, the material of dissolving tank can be PE / PP / PVC / carbon steel / stainless steel according to the environmental requirements, and the volume can be 100-2000l according to the water treatment capacity requirements;

2. Medicine storage barrel: the medicine storage barrel is placed under the medicine dissolving barrel, and the PAM solution dissolved in the medicine dissolving barrel flows to the medicine storage barrel by gravity for storage. The material can be PE / PP / PVC / carbon steel / stainless steel according to the environmental requirements, and the volume can be 100-10000l according to the water treatment capacity requirements;

2. Mixer: material can be PP / PVC / carbon steel / stainless steel / carbon steel rubber lining according to requirements, shaft length: 100-5000mm, blade diameter: 100-3000mm, blade layer number: 0-3, power: 0.12kw-11kw, speed: 0-80rpm;

3. PAC polyaluminum chloride dosing device metering pump: pump head material according to the use environment can choose PP / PVC / PVDF / stainless steel 304 / stainless steel 306, flow range: 0-5000l / h, pressure: 0-50mpa;

4. Safety valve back pressure valve: PVC / stainless steel 304, diameter: DN 15-dn 40, pressure: 0-50 MPa;

5. Buffer: PVC / stainless steel 304, volume: 0.5-20l;

6. Backwash device of PAC polyaluminum chloride dosing device: backwash Y-type filter, metering pump and its pipeline system for several minutes regularly or before pump shutdown, so as to ensure that the pipeline system is clean and unobstructed, and solve the blockage phenomenon;

7. Control cabinet: turbidity meter, flowmeter, etc. can be selected to collect field data and upload them to the upper computer for linkage control of reagent dosing;

二、 Precautions for PAC dosing device

1. Check that all pipes and valves are in normal working condition.

2. Check that the stepless speed regulator, magnetic pump and agitator of each dosing equipment are in normal working condition.

3. Check that the electrical equipment is in normal working condition.

4. All chemicals must be stored separately to prevent moisture.

5. The dosing equipment shall be inspected regularly and the sundries in the dosing tank shall be discharged regularly.

6. Regularly check the lubrication condition of mixing stepless governor and magnetic pump, and carry out maintenance once every three months.

If you want to do a good job in the dosing operation, in addition to the above knowledge, the device is also very important, so you must choose professional equipment to put into use, only in this way can you guarantee the later operation and reduce the probability of problems.
