The negative pressure thermal analysis apparatus operation principle of the present invention is as follows:
First, high water content sludge is entered in negative pressure thermal analysis apparatus by charging aperture 11, after charging aperture 11 is processed,
Mud is evenly distributed on the guipure 134 of mummification transporting reticulation belt equipment 13, automaton 2 passes through by certain thickness
The rotating speed of line traffic control frequency conversion motor, cooperation reductor controls the rotating speed of drivewheel 132, thus controlling mummification transporting reticulation belt equipment 13
Guipure 134 gait of march, while high water content sludge is advanced on guipure, part moisture can ooze from the mesh of guipure
Under filter, fall on water filtration separator 14, by drainage collecting device 15, filter water extraction is processed.
But when mud advances to end on guipure 134, due to shuttle operating structure, mud can be at guipure 134 end
End falls, because three mummification transporting reticulation belt equipment 13 are stepped in staggering, therefore the mud falling can be fallen next mummification and pass
On the guipure 134 of defeated guipure equipment 13, can not fall because the high-moisture percentage of mud can lead to partial sludge to be attached on guipure 134
Under, now automaton 2 controls air-introduced machine 6 to introduce high-temperature flue gas, sprays high-temperature gas by high-temperature flue gas spout 17, is inciting somebody to action
The mud of attachment blow off the guipure to next mummification transporting reticulation belt equipment 13 while also play the role of a mummification to mud.
High water content sludge passes through the mummification of said process and removes water, processes eventually through sludge outlet 18 natural excrement.
Wherein, high pressure backwashing equipment 16 adopts water jets under high pressure on demand or opens within the fixed cycle, within cleaning
Water filtration separator 14, water jets under high pressure connects, by line, the high-pressure hydraulic pump 3 controlling by automaton 2 to be provided.
Above-mentioned high-temperature flue gas spout 17 is while persistently blowing off the mud being attached on guipure 134 additionally it is possible to be to protect
Warm space make-up temperature and cleaning guipure 134 prevent guipure hole plug, and high-temperature flue gas spout 17 can enable the temperature in space
It is maintained within the temperature range of requirement, meet the requirement of the mummification temperature of mud on transporting reticulation belt 134, mummification in closing space
The humid flue gas that mud produces then by air-introduced machine 6 after exhanst gas outlet 12 pump-and-treat system qualified discharge it is ensured that in closing space
Smoke moisture scope within requiring.Mud after being processed by said process will greatly reduce moisture, the character of mud
Also will change, and solid-state like mud fragment can be become by muddy water shape liquid sludge.
