Because material is better mobile; Therefore the rotation of blade 422 can drive the Flow of Goods and Materials in the reactor drum tank body 201; And the baffle plate 403 that the autoreactor inner tank wall is given prominence to is through stopping flow direction of material and making material produce moving of vertical direction along the baffle plate direction; Thereby form convection current up and down, be beneficial to the uniform mixing of material and be heated.
Preferably; In the agitating vane assembly 402 the blade 422 of below stretch in the end socket of reactor drum tank body; The material that then inputs in the reactor drum tank body 201 falls into earlier in the end socket 207; Materials in the end socket 207 stir through the drive of blade 422, can realize the uniform mixing of material and are heated, and avoid forming stirring the blind area.And along with the continuous input material liquid surface of material rises to other blade 422 places, the combination of blade 422 and baffle plate 403 can both mix and be heated by the intravital material of realization response device jar uniformly.When the temperature of charge in the reactor drum tank body 201 had reached reaction conditions, material can export flashing reactor to through material outlet 205.
Cotton-shaped solid accumulation occurs and form obstruction for fear of material outlet 205, the caliber of material outlet 205 should be tried one's best greatly, and to guarantee the unimpeded of discharging, promptly the diameter of material outlet 205 should be greater than the diameter of material inlet 204.Preferably, big one or two grade of the diameter of the comparable material inlet 204 of the caliber of material outlet 205.For example the caliber of material inlet 204 is DN50, and material outlet 205 calibers exceed one or two grade so, are taken as DN65 or DN80.
Preferably, for the thorough mixing of realizing material, the purpose of thermally equivalent, the motor of whisking appliance 202 adopts frequency control motor, and can be set to be operated in than the slow speed of revolution.
Further, for fear of material sagging phenomenon occurring, the outside surface of the internal surface of reactor drum tank body 201 and whisking appliance 202 all need carry out polished finish, and its material should be chosen as according to material characteristic and has erosion resistance and anti abrasive material.
The hydrothermal reactor of the sludge water heat drying treatment unit of the utility model is to the big characteristics of material viscosity; Increased the function of first stirring, back chopping; Not only avoid in the reactor drum tank body, occurring stirring the phenomenon of blind area, generation solid accumulation; And make material in the reactor drum tank body, realize chopping fully, stir, to reach the purpose of homogeneous.Through using the hydrothermal reactor of the utility model, can make the mud material that hydro-thermal reaction can take place to mud material even heating and pressurize full and uniformly, thereby realize the purpose of dehydration.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
