It is divided into two flows below according to function of the present utility model to be illustrated.
Compression heat regeneration flow：Using the first described tank body as regeneration barrel, the second described tank body is as absorbing cylinder
Example.High-temperature gas enters described air inlet pipe and is split, and portion gas enters the first described pipeline 1 as first regeneration gas, separately
A part of gas enters the second described pipeline 2 as gas to be dried.Now, the 13rd described control valve K13 is opened, and is led to
Cross the size of the valve passage of the 13rd described control valve K13 of control and lead to the gas of the first pipeline 1 and the second pipeline 2 to control
Body flow proportional.Now, the 3rd described control valve K3 is opened, and the 5th control valve K5 is closed, and regeneration gas passes through described the tenth
Three control valve K13 and the 3rd control valve K3, then from the first described tank body（The drying tower of enough steam is absorbed）A ends
Into flowing through the adsorbent that need to be regenerated, using heat possessed by regeneration gas, to adsorbent heat temperature raising, obtain adsorbent
Thorough dehydration regeneration, due to, without gas consumption, farthest having saved energy in thermal regeneration process.The 8th described control valve

The 13rd control valve K13 aperture open to 75% or so, the gas for being now diverted to the connecting line of described heater 7 accounts for
1/3 or so of the total tolerance of high-temperature gas flow, in field adjustable, fine-tuning proportional control valve, it is ensured that pass through described heater 7
Gas outlet temperature more than 180 DEG C so that regeneration gas temperature is sufficiently high, can fully heat adsorbent, reach and regenerated
Full effect.
Regeneration gas by the second described cooler and the gas to be dried by the first cooler lead to described the
Four pipelines 4, new gas to be dried is converged in connecting line, the 12nd described control valve K12 and the 11st control valve K11 are opened
Open, the tenth control valve K10 is closed, described new gas to be dried, dry in absorbing cylinder into the B ends of the second described tank body
Drying prescription brings out after being adsorbed from the A of the second described tank body, enters outlet via the second described control valve K2 again afterwards
Pipe.

Open, the 9th described control valve K9, the tenth control valve K10, the 7th control valve K7 are closed；The gas passed by the first tank body out
The 3rd described control valve K3 of body warp leads to the 6th pipeline 6, then leads to the 4th pipeline 4, and be directly communicated to the portion of the second tank body
Divide gas, converge and lead to the second tank body, the 12nd described control valve K12, the 11st control valve K11, the second control valve K2 are opened
Open, the 4th described control valve K4 is closed.In order to prevent reverse adsorption during described cold blowing, adsorption column outlet temperature can be passed through
Degree controls the cold blowing time, and temperature spot may be configured as 60 DEG C, because adsorbent at >=60 DEG C substantially without adsorption effect, therefore when detection
When reaching 60 DEG C to cold blowing air outlet temperature, stop cold blowing flow, but now adsorption tower temperature from top to bottom about at 40 DEG C to 60 DEG C
It is distributed into ladder, to prevent that adsorption temp rise influences performance after next stage double tower from switching, and can increase 5min on stream
Double tower adsorption time, it is ensured that performance during switching is unaffected.
Further, the utility model can use cooling driers, can be controlled by after cooler air outlet temperature, can be by temperature
Point is arranged to 38 DEG C, and in after cooler escape pipe reload temperature sensor, if air outlet temperature >=38 DEG C, cooling driers are opened automatically
Open, cooling driers design intake air temperature is 10-50 DEG C, to ensure that equipment being capable of normal operation in summer.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from it is of the present utility model spirit or surmount scope defined in appended claims, this
A little change also should be regarded as the scope of protection of the utility model.
