Abstract

The invention discloses a zero gas generator comprising an air compressor, an air-water separator, a molecular sieve, a pressure control valve and a filter group which are connected in sequence, wherein a pipeline arranged between the molecular sieve and the pressure control valve is connected with an air storage tank. Through additionally providing the molecular sieve, the zero gas generator can further filter out and remove water in air so that the water removal is more thorough; the air storage tank is added to adjust the pressure so that the output pressure is more stable. The zero gas generator has relatively simple entire structure, stable and reliable performance, high filtering and removing efficiency and low noise.

Description

technical field [0001] The invention relates to a gas treatment device, in particular to a zero gas generator. Background technique [0002] Zero gas is the gas that adjusts the minimum scale of the gas analyzer, and the gas that shows zero when entering the analyzer. The zero gas should not contain components to be sided or interfering substances, but may contain components irrelevant to the determination. Generally, high-purity nitrogen or clean air that does not contain the components to be measured is used as the zero gas. The zero gas generator is a device used to process air to obtain zero gas. It can be widely used in environmental monitoring stations, industrial and mining enterprises, etc. as a zero point calibrator for gas analysis instruments. Existing zero gas generators, such as American Thermoelectric 111 zero gas generators, such as figure 1 As shown, the treatment process is to let the air pass through the air compressor, the water storage bottle, the pres...
