The system integrates bag-breaking, unloading and dust-removing functions, which solves the problem of dust flying in the process of adding and avoids possible environmental pollution and dust deflagration, and at the same time reduces the labor intensity of workers. The whole system is a complete set of equipment, the bag breaking capacity is calculated according to the following formula:
(water plant water volume of 300,000 cubic meters / day, the activated carbon dosage of 20mg / l, activated carbon per bag of 25kg)
The bag breaking capacity = the water plant water volume * the activated carbon dosage/1000/24/25
= 300000 * 20 / 1000 / 24 / 25
=10 bags/hour
2. Mixing tank and stirring device
The mixing tank mixes the activated carbon powder with water, and then formulates the suspended emulsion into a certain concentration through stirring. Its effective volume is calculated according to the following formula:
(water quantity of water plant is 300,000 cubic meters/day, activated carbon dosage is 20mg/l, preparation concentration is 10%)
Effective volume = water quantity of the water plant * activated carbon dosage/1000/24 / preparation concentration
= 300000 * 20 / 1000 / 24 / 10%
= 2500kg
This is a kind of mixing tank which is used to mix activated carbon powder and water to form a suspension emulsion of certain concentration through mixing. 2500kg
= 2.5m3
3, spraying dust removal device
The device is installed above the mixing tank, spraying the mixing tank with water in the air and around the tank, and flushing the dust that may be generated in the mixing process into the mixing tank.
4, dosing screw pump
For the configuration of the activated carbon suspension emulsion quantitatively added to the dosing point, the flow rate is calculated according to the following formula:
(water plant water volume of 300,000 cubic meters / day, the activated carbon dosage of 20mg / l, the preparation of the concentration of 10%)
The flow rate = the water plant water volume * activated carbon dosage/1000/24 / the preparation of the concentration
=300000 p>
=300000 * 20 / 1000 / 24 / 10%
=2500kg/h
=2.5m3/h
5. Piping system
Piping system
Piping is made of UPVC pipe, which is corrosion-resistant, and doesn't produce rust and corrosion to pollute water quality.
6, electronic control system
The electronic control system controls the starting and stopping of each equipment, realizing the dosing automation.
