LABORATORY INSTALLATION FOR MEASURING VOLUME OF BIOGAS PRODUCED BY DECOMPOSITION OF ORGANIC MATERIALS IN ANAEROBIC CONDITIONS

摘要

The utility model refers to laboratory equipment, namely, to the installation facilities under anaerobic conditions of biodegradability, the biogas potential of organic materials by measuring the volume of biogas formed. The technical result is an increase in the accuracy of measurements and reliability of the results obtained in the study of highly heterogeneous organic materials with a high gas generating capacity due to a sufficiently high mass of the material being investigated and eliminating the need for increasing the free space in the incubation chamber of the installation and avoiding a risk of leakage. The essence of the useful model is that in a laboratory installation for measuring the volume of biogas produced by the decomposition of organic materials under anaerobic conditions, comprising a hatching chamber 1 with a sealed cover 2, a gas measuring system according to claim 1 of the formula, the gas measuring system comprises a pressure vessel 10 with a pressure fluid 9 in which a gas-receiving graduated container 5 is placed upwards, a gas-evacuation tube 3 with a single-way valve 4 installed in a cover 2 of the incubation chamber 1, a gas sampling tube 6 with a single-pass valve 12, as well as a tube 7 and a discharge container 8 of the displaced pressure liquid 9, the gas-discharge tube 3 being located inside the pressure vessel 10 with the possibility w biogas inlet 15 into the inner space of the gas inlet vessel 5, and the sampling tube 6 - gas inlet at the top of the container 5, with the fence 15 biogas pressure above the liquid level 9, the discharge tube 7 is disposed in the upper part of the pressure vessel 10 and the sealed cover 2 is made with a technical pipe 11. In addition, according to claim 2, the pressure liquid 9 is an acidified saline solution, 1 zp. f-ly, 3 ill.
