Full-automatic internal circulating gas drying device

Abstract

The invention discloses a full-automatic internal circulating gas drying device. A front oil removing filter is respectively connected with a first drying tower and a second drying tower through a first valve and a second valve; the first drying tower and the second drying tower are both filled with moisture absorbents; the first drying tower and the second drying tower are respectively connectedwith a rear dust removing filter through a seventh valve and an eighth valve; the rear dust removing filter is connected with a finished product gas output system; the first drying tower and the second drying tower are also respectively connected with a regeneration gas regulating valve through the seventh valve and the eighth valve; the regeneration gas regulating valve is connected with a pressure blower; the pressure blower is connected with an electric heater; the electric heater is respectively connected with the first drying tower and the second drying tower through a fifth valve and a sixth valve; the first drying tower and the second drying tower are respectively connected with a cooler through a third valve and a fourth valve; the cooler is connected with the inlet of the front oil removing filter or the first valve and the second valve; and the first drying tower and the second drying tower form a circulating operation form that one of the first drying tower and the second drying tower adsorbs and the other one regenerates. The full-automatic internal circulating gas drying device has a reasonable structure and is good in working performance.

Description

technical field [0001] The invention relates to a gas drying device. Background technique [0002] With the rapid development of gas drying technology and the widespread application of adsorption dryers, the unit comprehensive energy consumption of product gas has become an important parameter to evaluate the drying performance of drying equipment. While ensuring the quality of product gas is stable, the energy consumption of equipment can be minimized , has become the development direction of drying technology and the goal of scientific research. At present, most of the adsorption drying equipment uses part of the product gas for regeneration in the process. For example, the heatless regeneration adsorption dryer has short switching time, high frequency, and large regeneration gas consumption (10~16%), while the heat regeneration adsorption dryer The heater needs the heater to heat the gas, and consumes 8~12% of the finished gas at the same time. Therefore, the large cons...
