Problems solved by technology

One is to use the auxiliary booster device to recycle the regeneration gas into the system, which requires additional energy consumption
One is to regenerate the adsorbent in the drying tower with the gas generated by the auxiliary device (such as a blower), which requires a large power consumption. On the other hand, it cannot be used for adsorption drying of flammable and explosive compressed gases, and cold blow also consume a small amount of compressed gas

Embodiment Construction

[0015] The present invention will be further described by using the accompanying drawings, but the examples in the accompanying drawings do not constitute any limitation to the present invention.

[0016] Workflow one of the present invention (A tower heating regeneration), such as figure 2 Shown:

[0017] The unsaturated high-temperature gas above 110°C discharged by the compressor PA is divided into two paths, and the flow distribution is automatically adjusted by the manual regulating valve NV and the self-adaptive micro-pressure automatic regulating valve V according to the working conditions, one of which flows through the automatic control valve BUV2, Adaptive regulating valve V, rear cooler C1, the gas cooled to below 40°C flows to the mixing tee M. The other gas flows to the heater H through the manual regulating valve NV, the automatic control valve BUV1, and the four-way valve ABV3. If the compressor exhaust temperature is lower than 110°C (otherwise the heater wil...

Abstract

The invention relates to a zero-discharge absorption-type compressed gas drying method and a drier. The absorption-type compressed gas drier comprises a pipeline inlet connected with a gas connected with and a pipeline outlet used for providing low dew point compressed gas, and the zero-discharge absorption-type compressed gas drier is arranged between the pipeline inlet and the pipeline outlet. The zero-discharge absorption-type compressed gas drier comprises an automatic control cabinet, a micro pressure automatic regulating valve and several control valves, and also comprises a front heater, a central section cooler, a central section gas-water separator, a rear portion cooler, a rear portion gas-water separator, and two adsorption towers with a fully filled adsorbent. The zero-discharge absorption-type compressed gas drier is characterized in that compressed gas discharged by the compressor is deeply dried, even the dew point of -70 DEG C can be reached, and the zero discharge of a whole process can be realized.

Description

technical field [0001] The invention relates to a dryer, in particular to a zero-emission adsorption compressed gas dryer. Background technique [0002] At present, there are three main types of zero-emission compressed gas purification devices. One is to use the auxiliary booster device to recycle the regeneration gas into the system, which requires additional energy consumption. One is to regenerate the adsorbent in the drying tower with the gas generated by the auxiliary device (such as a blower), which requires a large power consumption. On the other hand, it cannot be used for adsorption drying of flammable and explosive compressed gases, and cold blow Also consume a small amount of compressed gas. The last one is to use all the intake air directly for regeneration. A small amount of compressed gas still needs to be discharged during cold blowing. The filling amount of the adsorbent is large and the load of the double rear coolers is large. The cooling water or co...
