Abstract

The invention relates to a linkage control method for a low-pressure gas storage cabinet and a booster fan. The method is characterized in that that a balance weight plate is arranged in the multi-bag-cavity low-pressure gas storage cabinet, and at least two sets of Hall proximity sensors are arranged at the high position and the low position in the multi-bag-cavity low-pressure gas storage cabinet separately, wherein the position of the balance weight plate indicates the amount of biogas in the multi-bag-cavity low-pressure storage gas cabinet, and the at least two sets of Hall proximity sensors are used for sensing the proximity of the balance weight plate; when the balance weight plate of the multi-bag-cavity low-pressure gas storage cabinet reaches the high position or the low position, the Hall proximity sensors are used for generating a switch signal and sending the switch signal to a control cabinet; the control cabinet is used for converting the switch signal into start-stop signal for the booster fan and sending the start-stop signal to the booster fan; and the booster fan is started or stopped according to the start-stop signal so as to convey biogas in a large-capacity bag-cavity type gas storage cabinet to the multi-bag-cavity low-pressure gas storage cabinet or stop conveying the biogas in the large-capacity bag-cavity type gas storage cabinet to the multi-bag-cavity low-pressure gas storage cabinet.

Description

technical field

[0001] The present invention relates to a method for automatically replenishing gas from a biogas storage tank in low-pressure biogas transmission and distribution, and more specifically relates to a linkage control method between a low-pressure gas storage tank and a booster fan, which controls the operation of the booster fan according to the gas volume of the low-pressure gas storage tank to achieve linkage control. Background technique

[0002] Existing composite gas holder systems include multiple multi-cavity low-pressure gas holders, large-capacity air storage bags, controllers, pressure sensors, booster fans, etc. These components are combined into a constant-pressure exhaust system.

[0003] For single biogas projects with a tank capacity of less than 1000 cubic meters, there are problems such as unstable gas production, frequent fluctuations in gas production and gas consumption, and inconsistent time points between gas production peaks and gas cons...
