Description

technical field [0001] The invention belongs to the related technical field of suction filtration equipment, and more specifically relates to a suction filtration system and a solid-liquid separation method suitable for solid-liquid separation. Background technique [0002] Modern society relies heavily on traditional fossil energy. According to statistics, about 74% of the world's total energy consumption comes from primary energy such as coal, oil, and natural gas. Although fossil energy has promoted the progress of society, non-renewable energy is being exhausted day by day, and at the same time, it will cause serious environmental pollution problems, which seriously threaten the survival and development of human beings. Biomass energy is a kind of renewable energy that can be stored. During its utilization, it can realize zero emission of carbon dioxide by relying on its own carbon cycle. It is a renewable carbon source, and there are abundant biomass reserves on the ear...

Problems solved by technology

In the laboratory, it is generally necessary to filter and wash through multiple washing liquids. Traditional suction filtration devices usually require experimenters to use beakers or other containers to hold and add washing liquid back and forth, which is complicated to operate.

At the same time, the outlet of the filter head of the traditional laboratory suction filtration device is set horizontally. After the actual suction filtration experiment, it is found that it is easier to suck the liquid into the rubber tube and then into the vacuum pump, which will easily cause various unfavorable problems such as damage to the vacuum pump and reduced filtration efficiency. influences

In addition, the commonly used clamping method for laboratory suction filtration devices is to use a simple clamp. Although this method is simple and feasible, it is easy to cause the seal to be not tight enough, thereby reducing the efficiency of suction filtration, and because the speed of suction filtration itself is very slow, Some suction filtration processes even take more than a few days. The amount of washing liquid required for suction filtration is large, and the capacity of the Buchner funnel commonly used for suction filtration is small. If you do not pay attention, the washing liquid in the Buchner funnel will was drained, causing the filter paper to rupture and the solid product in the Buchner funnel to fall into the filter bottle, resulting in the failure of the suction filtration process
