Be accompanied by the fast development of global economy and people to the growing interest of environment, sewage load increases at a high speed, has caused the rapid expansion of sludge yield.At present, China's annual discharging dewatered sludge is about 5,000,000 tons, and quantity is also constantly increasing.If the improper meeting of sludge treatment causes serious secondary pollution, and the investment of sludge treatment and working cost are huge, account for 25%～65% of whole Sewage Plant investment and working cost, become the heavy burden that the municipal sewage plant faces.Therefore, economic, efficient treating excess sludge how realizes that sludge stabilizing, innoxious, resource utilization are the current important topics that solve be badly in need of.
Contain a large amount of microorganism cellss and organism colloid in the mud, caused the sludge dewatering difficulty, the dehydrated sludge cake water ratio is up to about 80% usually.The means of sludge disposal mainly comprise compost, landfill and burning.
When mud is used for compost material, usually need to add the amendment reduction moisture to 50～60%, the amendment total amount that needs to add is about 60% of mud, and such as finding no sale of sludge composting product, sludge quantity does not only reduce on the contrary increase.
Mud is admitted with garbage sanitary filling field in domestic indivedual city, because moisture percentage in sewage sludge is high, easily cause landfill operation difficulty, leachate quality deterioration and landfill heap body unstable, therefore, in fact, at present most domestic garbage sanitary filling field refusal mud is marched into the arena.
Burning is the effective means that realizes sludge reduction, and the calorific value that usually requires to burn material is greater than 1200 kcal/kg, according to the average shale level of municipal sludge, only has water ratio could satisfy this requirement less than 50% the time.Therefore the dehydrated sludge cake of water ratio 80% all should not be directly processed in landfill, compost and burning, and for satisfying disposal standard and arts demand, water ratio will be reduced to below 60% at least.How efficient low-consume ground is reduced to 60% with moisture percentage in sewage sludge by 80%, becomes the key problem in technology that ensures that mud is effectively disposed.This adopts the mummification mode usually.But sludge drying need to consume a large amount of energy, and as adopting the steam mummification, one ton of mud need to consume the steam of 0.8-1 ton, and running cost is high.
The sludge dewatering difficulty is that to this, people have done a large amount of correlative studys because the water in the mud is subject to the constraint of multi-acting force.The hydro-thermal drying technique is rapidly a kind for the treatment of process of development in recent years, by with the mud heating, makes the viscosity hydrolysis of organic matter in the mud under certain temperature and pressure, destroys the colloidal structure of mud, can improve simultaneously dewatering and anaerobic digestion performance.With the increase of hydrothermal temperature and pressure, the particle collision probability increases, and intergranular collision has caused the destruction of colloidal structure, and irreducible water is separated with solid particulate.In addition, heating is decomposed the protein in the mud, and cell breaks, and the moisture in the born of the same parents is released.Pass through the mud of hydrothermal treatment consists in the situation that do not add flocculation agent, mechanical dehydration can make below the water ratio decrease to 50%, has greatly improved the dewatering of mud, and Sludge Disposal Techniques is to possibility low-cost, sustainable future development.
But existing sludge water heat drying treatment device exists the problem that reaction effect is relatively poor, the material continuity is relatively poor, so the efficient of sludge water heat drying is still very low.

The materials that input in the reactor tank body 201 fall into first in the end socket 207, and the materials in the end socket 207 stir through the drive of stirring anchor frame 421, can realize the even 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 stirring frame 422 places, the combination of the stirring frame 422 of a plurality of different sizes can both mix and be heated by the interior material of realization response device tank body uniformly.When the temperature of charge in the reactor tank body 201 had reached reaction conditions, material can export hydrothermal reactor to by 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, namely the diameter of material outlet 205 should be greater than the diameter of material inlet 204.Preferably, large 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 abundant mixing that realizes material, the purpose of thermally equivalent, the motor of agitator 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 tank body 201 and agitator 202 all needs to carry out polished finish, and its material should be chosen as according to material characteristic and has erosion resistance and anti abrasive material.
The pulp reactor of sludge water heat drying treatment device of the present utility model is for the large characteristics of material viscosity, increased the function that stirs first, passes into steam preheating, not only avoid in the reactor tank body, occurring stirring the phenomenon of blind area, generation solid accumulation, and make material in the reactor tank body, realize sufficient preheating, stirring, to reach the purpose of pulp.By in the reactor tank body, passing into steam, forming the environment of certain temperature and pressure, and make material carry out quickly and evenly mass-and heat-transfer by the stirring of agitator, to promote the temperature of mud material, ready for carrying out hydro-thermal reaction.By using pulp reactor of the present utility model, can solve the problem of the material poor continuity of existing sludge drying processing, be conducive to improve efficient and the quality of sludge water heat drying.
