Abstract
The invention discloses a gas dilutor. The gas dilutor comprises 1, an A path gas inlet, an A path orifice flow sensor, an A path air-capacitor and an A path diaphragm pump orderly connected, 2, a B path gas inlet, a B path orifice flow sensor, a B path diaphragm pump and a B path one-way valve orderly connected, 3, a three-way valve connected to the A path diaphragm pump and the B path one-way valve, 4, a mixed gas outlet connected to a gas outlet of the three-way valve, 5, a control system, 6, an input / output device, and 7, a gas pressure and temperature sensor. The control system is connected to the A path orifice flow sensor, the B path orifice flow sensor, the A path diaphragm pump, the B path diaphragm pump, the input / output device and the gas pressure and temperature sensor. The gas dilutor has a compact structure, a small volume and light weight, is convenient for carrying, has a high intelligentization degree, a wide diluted-concentration range, a high preparation precision and a high flow precision, and can be used for diluting special gas containing steam, dust and organics such as oil gas.
Description
technical field [0001] The invention relates to a gas diluter, which is used for generating gas with a specific dilution ratio, and is especially suitable for diluting special gas containing organic matter such as oil and gas, water vapor and dust. Background technique [0002] Existing gas diluters mainly use mass flow controllers to generate a mixed gas with a specific dilution ratio by controlling the flow. This type of instrument has the following problems: 1. With the increase of the dilution factor, the precision of the mixed gas will be greatly reduced, resulting in inaccurate gas distribution; 2. Due to the mass flow controller, it is impossible to control the gas containing oil, dust, water vapor, etc. 3. It is impossible to provide on-site gas distribution, and the work efficiency is low. [0003] Therefore, to provide a gas diluter that can accurately distribute gases containing special components such as oil, gas, dust, water vapor, etc., has a simple structure,...
