1. flasks are mainly used for reactions between solutions or between liquids and solids. It can be heated, but it needs to be padded with asbestos mesh, and a gas generator can be assembled. Commonly used instruments in filtration are glass rods, beakers and funnels. Pay attention to the principle of one low, two stickers and three supports when filtering. The function of beaker and funnel is to heat and control the reaction.
2. Funnel is an instrument used for filtration. By pouring the liquid into a small mouth container, a pungent and water-soluble gas is generated, which is used to assemble the tail gas absorption device and the filtering device. The function of the funnel is to make the liquid flow into the container smoothly by controlling the inclination of the funnel, so as to realize the filtration process.
3. Instruments needed for filtration include glass rods, beakers and funnels. Glass rod is a kind of stirring and drainage device, which is mainly used to filter or transfer liquid. Be careful not to use too much force, not to hit the wall of the instrument, and clean it in time to prevent pollution. Don't put the end of the glass rod immersed in liquid on the table. Pay attention to the principle of one low, two stickers and three leanings when filtering to ensure the filtering effect.
4. Bag filter is a new type of water filtering equipment, and the main filtering medium is filter bag. It consists of filter cartridge, filter cartridge cover, quick-opening mechanism, stainless steel filter bag reinforcing net and other main components. The filtrate flows into the filter bag from the side water inlet pipe of the filter shell, and the filter bag itself is installed in the reinforced mesh basket. When the liquid permeates through the filter bag with the required fineness grade, the impurity particles are intercepted by the filter bag, and the qualified filtrate can be obtained.
The purpose of filtration
Filtration is the process of separating impurities or solid particles in the mixture from the fluid by physical or chemical methods. The purpose of filtration is to make the fluid clearer or purer, or to remove impurities or solid particles in it to meet different application requirements.
There are many kinds of filtration methods and equipment, including bag filter, filter element, filter screen, filter plate, centrifuge, steam filter and so on. According to different filtration methods and process characteristics, these filtration devices can filter different liquids or gases to remove suspended particles, impurities or sediments.
