Work process and the principle of system are described further.
In duty shown in Fig. 2, adsorption tower 1 carries out absorption process, adsorption tower 2
Carry out cold blowing operation, adsorption tower 4 and adsorption tower 5 with adsorption tower 3 and carry out hot blow operation.
For the ease of understanding the connection feelings of each pipeline of adsorption cleaning system under this duty
The opening and closing situation of condition and valve, gives the rough schematic view that Fig. 3, Fig. 3 are Fig. 2.Figure
The valve remained in 3 is all opened, valve not shown in Fig. 3 shown in Fig. 2
It is all Guan Bi, and then, the connection of pipeline can also be found out with being apparent from by the opening and closing of valve
Situation.
Below in conjunction with Fig. 3, further illustrate in absorption process, cold blowing operation and hot blow operation
Gas flow.
Absorption process: unstripped gas sequentially passes through unstripped gas house steward 10 and raw material from unstripped gas entrance
Gas branch pipe 11 enters into and carries out adsorption cleaning process in adsorption tower 1, is cleaned the raw material of process
Gas becomes purification gas and sequentially passes through purification gas branch pipe 21 and purify gas house steward 20 and go out from purifying gas
Mouth is discharged.
Cold blowing operation: regeneration gas from regeneration gas entrance sequentially pass through the first regeneration gas house steward 30,
First regeneration gas arm 31 and purification gas branch pipe 22 enter in adsorption tower 2 and carry out cold to adsorbent
Blowing, then unstripped gas arm 12 and the 3rd is discharged and sequentially passed through to this regeneration gas from adsorption tower 2
Regeneration gas arm enters regeneration gas chiller 6, and regeneration gas is carried out by regeneration gas chiller 6
Cooling, then cooled regeneration gas sequentially passes through the 4th regeneration gas arm and purifies gas branch pipe
23 entrance adsorption towers 3 carry out cold blowing to adsorbent.
Hot blow operation: the regeneration gas discharged from adsorption tower 3 is through unstripped gas arm 13 and the
Five enter regeneration gas heater 7 heats, and heated regeneration gas sequentially passes through the 6th again
Angry arm and purification gas branch pipe 24 enter in adsorption tower 4 and adsorbent are carried out hot blow；Connect
, regeneration gas sequentially passes through unstripped gas arm 14 and the 5th regeneration gas arm enters regeneration gas and adds
Thermal 8 heats, and heated regeneration gas sequentially passes through the 6th regeneration gas arm and purification
Gas branch pipe 25 enters and carries out hot blow in adsorption tower 5, and last regeneration gas sequentially passes through unstripped gas and props up
Pipe 15 and the second regeneration gas house steward 60 discharge from regeneration gas outlet.
Shown in Fig. 4 is the subsequent work state of the duty shown in Fig. 2, and Fig. 5 is to figure
3 simplify after schematic diagram.In the duty shown in Fig. 4, adsorption tower 3 is carried out
Absorption process, adsorption tower 2 and adsorption tower 4 carry out cold blowing operation, adsorption tower 1 and adsorption tower
5 carry out hot blow operation.
Can be clear that from Fig. 3 and Fig. 5, no matter under which duty, then
Angry chiller 6, regeneration gas heater 7 and regeneration gas heater 8 can and its
In four adsorption towers be in series connection, only just complete four absorption by a small amount of regeneration gas
Tower carries out the work of desorption, and therefore, this adsorption cleaning system of the present embodiment is to regeneration gas
Consumption greatly reduce.
