Embodiment 1

[0018] The leak test device of the biogas digester in this example is figure 1 As shown, the biogas digester sealing test device is composed of a biogas digester 1, a pressure gauge 4, a surface thermometer 5 and a liquid level sensor 6. The pressure gauge 4 is connected to the air duct 2 of the biogas digester 1, and the thermocouple wire of the surface thermometer 5 Part of it is pasted to the inside of the top of the gas chamber 3 of the biogas tank 1, and the probe end of the liquid level sensor 6 is placed at the bottom of the biogas tank 1.

[0019] The method of using the leak test device of the biogas digester in this example is as follows:

[0020] The first step is to measure the geometric dimensions of biogas digester 1, calculate the maximum volume of gas chamber 3, and measure the maximum height H of gas chamber 3 1 , The inner diameter of the bottom surface of the air chamber 3 r 1 And the maximum water height of the lower half of the pool H 2 , The air chamber 3 can ...

Abstract

The invention belongs to a biogas tank sealing test device in the field of testing devices, which is composed of a biogas tank (1), a pressure gauge (4), a surface thermometer (5) and a liquid level sensor (6), wherein the pressure gauge (4) ) is connected to the gas guide pipe (2) of the biogas digester (1), the thermocouple wire part of the surface thermometer (5) is pasted to the inside of the top of the gas chamber (3) of the biogas digester (1), and the probe end of the liquid level sensor (6) It is placed at the bottom of the digester (1). The invention solves the technical problem that the existing air chamber is a ball-deficient hard-body commercial biogas digester sealing test device that is difficult to ensure the accuracy of test data, and provides a biogas digester sealing test device for people with a simple structure, strong operability and high operability. High test accuracy.

Description

Technical field [0001] The invention belongs to the field of testing devices, and specifically relates to a method for testing the tightness of a biogas tank. Background technique [0002] At present, hardware commercial biogas digesters include glass fiber reinforced plastic biogas digesters, hard plastic biogas digesters, reinforced cement commercial biogas digesters and steel commercial biogas digesters. Most of the gas chambers of hard commercial biogas digesters are spherical. As for the test of the sealability of commercial biogas digesters of this kind, they are mostly tested and judged based on or refer to NY / T 1699-2010 "Glass Fiber Reinforced Plastic Household Biogas Digesters" standard. In the standard leak test method, only the change in air chamber pressure is measured, which is used as the basis for judging whether the air chamber is leaking or not. In actual operation, the atmospheric pressure and ambient temperature have changed before and after the pressure is ma...
