Problems solved by technology

There are several commonly used regeneration methods: heating with steam (need to heat up, consumes a lot of energy), or vacuuming (desorption is not thorough enough), or heating with hot air (the amount of gas used is large, additional heating is required, and the oxygen brought in There is a risk of burning or even explosion)

Embodiment Construction

[0012] Such as figure 1 The shown regeneration system using exhaust gas itself as a heating carrier has an adsorption-desorption tank containing adsorption fillers, and the adsorption-desorption tank has an exhaust gas inlet, a desorption gas inlet, a purified gas outlet, and a regeneration gas outlet; the desorption gas inlet What enters is the exhaust gas itself, and a heating device is installed on the pipeline between the exhaust gas source and the desorption gas inlet to heat the exhaust gas, and use the higher temperature exhaust gas to bake and desorb the adsorption filler.

[0013] The valve of the purified gas outlet can be closed at the initial stage of adsorption, opened at the later stage of adsorption, and closed during the whole desorption process; the valve of the regeneration gas outlet is closed during the whole adsorption process and opened during desorption.

Abstract

The invention discloses a regenerating system using waste gas itself as a heating carrier, which is provided with an absorption and desorption tank with an absorbing filler; the absorption and desorption tank is provided with a waste gas inlet, an absorption and desorption inlet, a purified gas outlet, a regenerating gas outlet; the waste gas is desorbed and absorbed by itself; a heating device isarranged on the pipeline between the waste gas source and the absorption and desorption gas inlet. By using the waste gas itself as the absorption and desorption gas source, no detonation is happened; the safety is good and the cost is low.

Description

technical field [0001] The invention relates to an adsorption regeneration device. Background technique [0002] The adsorption regeneration device (or adsorption regeneration tower) has the dual function of being able to adsorb harmful components in the exhaust gas and then desorb and regenerate them. There are several commonly used regeneration methods: heating with steam (need to heat up, consumes a lot of energy), or vacuuming (desorption is not thorough enough), or heating with hot air (the amount of gas used is large, additional heating is required, and the oxygen brought in There is a risk of burning or even explosion). Contents of the invention [0003] Purpose of the invention: To provide a regeneration system that uses exhaust gas itself as a heating carrier without consuming additional raw materials and bringing additional impurities. [0004] Technical solutions: [0005] The regeneration system using waste gas itself as a heating carrier of the present inve...
