Intelligent constant temperature and ultrasonic wave promoting desorption integrated coal sample tank and using method thereof

Abstract

The invention discloses an intelligent constant temperature and ultrasonic wave promoting desorption integrated coal sample tank and a using method thereof. The coal sample tank comprises a tank bodyand a tank cover, the tank cover is provided with an exhaust pipe, and the exhaust pipe is provided with a gas flow meter and an air exhaust valve. A temperature regulating inner container is arrangedon the inner wall of the tank body, and a thermal insulating layer is further arranged between the temperature regulating inner container and the inner wall of the tank body. A temperature sensor isinstalled in the tank body, and an intelligent temperature control device is installed on the side wall of the tank body. The temperature regulating inner container and the temperature sensor are bothelectrically connected with the intelligent temperature control device. According to the intelligent constant temperature and ultrasonic wave promoting desorption integrated coal sample tank and theusing method thereof, intelligent dynamic regulation and ultrasonic wave desorption promotion of the temperature inside the tank body can be performed for arbitrary downhole temperature, and adsorption gas in a coal sample is evenly oscillated, so that the gas desorption rate in the coal sample is accelerated, the desorption is more complete, and the determination of gas content in underground coal samples is more accurate.

Description

Technical field [0001] The invention belongs to the technical field of mining engineering, and particularly relates to a coal sample tank integrated with intelligent constant temperature and ultrasonic acceleration and desorption and a use method thereof. Background technique [0002] Coal seam gas content is not only one of the important parameters for predicting the risk of coal and gas outburst, but also determines whether the gas in the coal seam has the value of commercial exploration and development, and is an important basis for safe production and gas drainage design. The original gas content of the coal seam includes the amount of coal sample gas loss, coal sample desorption volume and residual gas volume. The accuracy of the underground gas desorption measurement directly affects the accuracy of the original coal gas amount. [0003] According to theoretical research and field measurement process, it is found that temperature and vibration have an important influence on ...

AI Technical Summary

Problems solved by technology

The existing measurement equipment has the following problems: the traditional coal sample tank does not have the function of heat preservation, and the coal sample tank with heat preservation function is only added with an insulation layer, which cannot intelligently adjust the temperature inside the tank for any downhole temperature; the traditional coal sample tank does not With vibration function, some coal sample tanks are added with a stirrer, which has an unsatisfactory desorption effect and makes the instrument bulky. Accurate, but also a waste of manpower and material resources
