Problems solved by technology

Nowadays, nitrogen-generating equipment is gradually developing towards miniaturization, and more and more are applied to small places such as laboratories. Large-scale nitrogen-generating machines are used in the hands of small and medium-sized users, and the cost investment is too large to bring too much to users. practical value

Abstract

The invention discloses a nitrogen separation device. The device comprises a separation device body, wherein the separation equipment body comprises a shell, an adsorption mechanism, a first valve mechanism, a second valve mechanism and a controller; the adsorption mechanism is arranged in a second cavity; the adsorption mechanism is respectively connected with an air compression device and a nitrogen buffer tank through the first valve mechanism; the nitrogen buffer tank is connected with the second valve mechanism; the adsorption mechanism comprises two adsorption towers, and the two adsorption towers are mutually connected through the first valve mechanism; the controller is arranged on the left surface of a separation plate and is electrically connected with the first valve mechanism and the second valve mechanism; and the two adsorption towers are arranged in the second cavity through connecting parts. According to the nitrogen separation device, nitrogen is prepared by a conventional eight-valve pressure-swing adsorption principle, the adsorption mechanism is installed in the shell and is safe and reliable, and the device is small in overall size and is suitable for small fields such as laboratories and the like. The maximum yield is 33 m<3> / h, and the gas outlet concentration can reach 99.999%.

Description

technical field [0001] The invention relates to the technical field of nitrogen preparation devices, more specifically, the invention relates to a nitrogen separation device. Background technique [0002] Pressure swing adsorption air separation nitrogen production (referred to as P.S.A nitrogen production) is an advanced gas separation technology. It uses high-quality imported carbon molecular sieve (CMS) as the adsorbent and adopts the principle of pressure swing adsorption (PSA) at room temperature to separate air to produce high-purity gas. Specifically, the diffusion rates of oxygen and nitrogen gas molecules on the molecular sieve surface are different, and the gas molecules with smaller diameters (O 2 ) The diffusion rate is faster, and more gas molecules enter the carbon molecular sieve pores, and the gas molecules with larger diameters (N 2 ) The diffusion rate is slow, and there are fewer micropores in the carbon molecular sieve. The difference in selective adsor...
