Abstract

The invention discloses a device and a method for condensing and separating water in methane, belongs to the field of methane purification, and aims at solving the problems that the operation is complex and the energy consumption is large in the process that water in methane is eliminated by using the conventional condensing method. The device comprises a first tank, a methane intake tube, a methane outtake tube, a methane outtake valve, a first water discharging tube, a first water discharging valve, a first floating ball level meter and an isolating film pump, wherein the first tank body is a sealed tank body; the first tank body is communicated with the methane intake tube; the upper part of the first tank body is further communicated with the methane outtake tube; the methane outtake valve is arranged on the methane outtake tube; one end of the first water discharging tube penetrates through the first tank body and penetrates into the bottom of the first tank body; the other end of the first water discharging tube is arranged outside the first tank body and is communicated with a liquid inlet of the isolating film pump; the first water discharging valve is arranged on the first water discharging tube; the floating ball on the first floating ball level meter is arranged inside the first tank body; and the lower end of the first tank body is arranged below the ground. The device and the method are applicable to methane purification.

Description

technical field [0001] The invention relates to a device and method for condensing and separating water in biogas, belonging to the field of biogas purification. Background technique [0002] With the promulgation of my country's Renewable Energy Law, people began to maximize the research and development of various renewable energy project technologies. Anaerobic fermentation technology is to ferment agricultural and animal husbandry and other biomass wastes to generate biogas for power generation. A technique that has been widely used. Therefore, in order to improve the efficiency and stability of the anaerobic fermentation system, there are more and more researches on various devices and treatment technologies in the anaerobic fermentation process. The temperature in the anaerobic fermentation process is relatively high, and the biogas contains water. At the same time, the biogas contains sulfurous gases such as hydrogen sulfide. If the biogas contains a lot of water, it w...
