Dust removal equipment in galvanizing plant and bag dust collector used in zinc powder treatment and recycling system of galvanizing plant have the characteristics of large flue gas and high efficiency. It is improved on the basis of the previous generation of dust collectors, with good heat preservation and anti-condensation effects, and is an ideal equipment for recycling zinc powder.
Dust removal equipment for galvanizing plant, zinc powder treatment design principles:
(1) Hot-dip galvanizing blows inside and outside instead of using ordinary gas source, but uses pressure steam. Because the moisture content in the steam is larger than ordinary gas, the zinc powder gas entering the dust removal equipment has a higher moisture content. The dust bag filters and purifies the zinc powder. Zinc powder is easy to stick, clogged, vent holes, and the recovered dust is in the form of solid mud. The filtering dust removal effect is poor. In addition, the amount of zinc powder accumulated on the bag is too large. Spontaneous combustion may occur, and the bag will be damaged. Measures are to be used for internal and external purge of steel pipes of dust removal equipment.
(2) Due to the high temperature of the zinc powder gas generated after hot-dip galvanizing, the bag material must not only have sufficient strength and air permeability, but also have high temperature resistance. The temperature of the zinc dust chamber (box) is generally below 200 ℃. The material of the selected bag does not deform at this temperature, and does not affect the permeability and strength. By comparing the dust removal area, air inlet and filtration speed of the bag, domestic polyester is selected. Needle felt cloth bag material.
(3) In order to prevent the high-temperature flue gas containing zinc dust from entering the dust removal equipment of the galvanization plant and the zinc powder treatment equipment of the galvanization plant, when it contacts the cold air in the ventilation duct and the dust collector to form condensation, it should be on the outer wall of the dust collector. Lay a thermal insulation layer and connect the steam channel to maintain the constant temperature of the dust collector room.
(4) In order to prevent the zinc in the zinc powder gas from being diffused without filtering and endangering human health, the sealing problem of the upper and lower chambers of the bag filter must be solved.
Structural principle of galvanizing plant dust removal equipment and zinc powder processing equipment:
During the galvanizing process, the flue gas after galvanizing decreases from high temperature. In this process, the flue gas absorbs the moisture in the air. Due to the effect of wind speed and airflow, especially in the northern region, the air suddenly changes in the cold and heat. Cooling. Condensed water is easy to form inside the pipe, and it is more difficult to clean the dust on the surface of the dust collector bag. Therefore, the choice of dust collector bag is very important. When waterproof and oil proof dust collector bag or temperature control is good, other filters such as polypropylene fiber can be used material.
》既保证了您在的使用效果，又节约了您的生产成本. 采取适当的加热措施。 Our company specially designed pulse bag type dust collector for galvanizing plant. " Working Principle of Bag Dust Collector " not only guarantees the effect of your use, but also saves your production cost. Take appropriate heating measures. For example, far-infrared electric heaters and electric heaters are installed in the dust removal equipment of the galvanization plant, or a radiator is installed in the bag dust collector, so that the flue gas temperature of the host can be appropriately increased. Strengthen the dust removal equipment and dust removal system of the galvanization plant. Temperature monitoring, to grasp the use of bag dust collectors to prevent condensation. Dust-containing gas should be evenly distributed in the dust collector to prevent condensation problems caused by eddy currents at the corners, reduce the amount of gas passing through the dust collector, and form a local low temperature .
