Abstract: Galvanizing plant electroplating pickling workshop processing will produce a large amount of waste gas, according to the provisions of the local environmental protection bureaus need to install a set of discharge dust concentration of the pulse bag filter is also known as bag filter, cloth bag Dust collector, boiler dust collector and so on.
Galvanizing plant electroplating pickling workshop and galvanized production process produce hydrochloric acid, sulfuric acid, nitrogen oxides and other harmful gases such as: hydrogen chloride, sulfur dioxide, hydrogen fluoride, hydrogen sulfide and phosphoric acid and other gases and acid mist. Some galvanizing plants use basic gases such as sodium hydroxide, sodium carbonate, and sodium phosphate due to heating and other process operations. There are also chromic acid mists produced in the chrome plating process, which are extremely toxic. And cyanide plating residues, such as cyanide copper plating, galvanized and imitation gold. The cyanide budget mixes to produce highly toxic hydrogen cyanide gas. It is very harmful to the human body and it also has great air pollution. According to the requirements of local environmental protection bureaus, it is necessary to install a set of pulse bag dust collectors with emission dust concentration standards, also known as bag filter, bag filter, boiler dust collector and so on.
What type of bag filter should be used for galvanizing plant flue gas treatment?
Regardless of the number of baghouses used in galvanizing plants, we first consider the emission concentration standards. If the emission concentration is not up to standard, we are almost equivalent to installing white bag filter. If the emission is not up to standard, our air will not be improved and our personal health will not be improved. Such as: 11 m × 1.7 m zinc pot requires a set of 900 square meters can handle bag filter.
Design concept: safe operation, low investment costs, low maintenance rate, clean dust treatment, small footprint, emissions to meet the "local air pollutant emission standards" and so on. So Haofeng engineers according to different requirements of users Galvanized plant site design different bag type dust removal equipment.
Design advantages First, the bag cage: bag cage as one of the core of the dust collector, Hao Feng uses a round skeleton (external filter type), which is the rib of the filter bag <<bag>>, lightweight design, easy installation and maintenance, dust The quality of the skeleton directly affects the filtering condition and service life of the filter bag.
Advantages in design II. Flower board: The thickness of the board is ≥ 6mm. The hole in the board is punched. According to the size of the board, the backboard is increased in the area of the board. The connection between the board and the bag cage is smooth without scratching the filter bag; the board is installed. Meet the relevant technical standards, the overall flatness after installation ≤ 5mm.
Advantages of Design III. Electrical Control Box: Composed of fan control and pulse control instrument, the introduction of power supply is 380V three-phase four-wire, contactor, continuation electric appliance, pulse control instrument, button, indicating composition of low voltage control system
Design Advantages IV. Impulse Valves: Impulse valves are assembled with high-quality materials. The number of injections can reach 1.01 million times. Anti-aging hoses can be connected and seals can be easily maintained.
5. Advantages of the design 5. No box weld welding, smooth appearance, increase the apron in the middle of the box, strengthen the box to reduce the resonance noise.
