Description
Technical field
The present invention relates to the sludge water heat drying processing technology field, particularly a kind of sludge water heat drying treatment device and hydrothermal reactor thereof.
Background technology
Be accompanied by the fast development of global economy and the people growing interest to 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 municipal sewage plant faces.Therefore, economic, efficient treating excess sludge how, realize that sludge stabilizing, innoxious, resource utilization are the current important topics that solves of being badly in need of.
In mud, contain a large amount of microorganism cellss and organism colloid, caused the sludge dewatering difficulty, the dehydrated sludge cake water ratio is up to 80% left and right 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 need to add is about 60% of mud, and as finding no sale of sludge composting product, sludge quantity does not only reduce increase on the contrary.
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, usually requires the calorific value that burns material greater than 1200 kcal/kg, according to the average shale level of municipal sludge, only has water ratio could meet this requirement less than 50% the time.Therefore landfill, compost and burning all should not directly be processed the dehydrated sludge cake of water ratio 80%, and for meeting disposal standard and technique needs, water ratio will be reduced to below 60% at least.How efficient low-consume ground is reduced to 60% by 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 adopted 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 due to the water in mud, to be subject to the constraint of multi-acting force, and to this, people have done a large amount of correlative studys.The hydro-thermal drying technique is development in recent years a kind for the treatment of process rapidly, and by by mud heating, the viscosity hydrolysis of organic matter make mud under certain temperature and pressure in, destroy 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 the collision that particle is asked has caused the destruction of colloidal structure, and irreducible water is separated with solid particulate.In addition, heating is decomposed the protein in mud, and cell breaks, and the moisture in 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 water ratio decrease to 50%, greatly to have 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 poor, the material continuity is poor, so the efficiency of sludge water heat drying is still very low.
