Description
Technical field
The utility model belongs to biological sludge recycling treatment field, is related to a kind of intermittent pyrohydrolysis system.
Background technique
With the continuous development of society and economy the yield of the biological sludges such as biogas residue, activated sludge is increasing.Currently,
The pretreated research hotspot of biological sludge include high-temperature-hot-water solution, biological acidification hydrolysis, high temperature and pressure oxidation, ultrasonication,
High temperature homogeneous, ozone chemistry processing etc., wherein the characteristics of high-temperature-hot-water solution technology is that biological sludge is warmed to 150-180 DEG C,
To achieve the purpose that destroy flocculation structure, destroy cell wall tissue and degradation part macromolecular substances.Due to high-temperature-hot-water solution energy
Solid particle and macromolecular substances difficult to degrade be in enough bio-sludge degradings to increase the content of organic acid and dissolved organic matter,
In this, as the preposition preprocessing process of anaerobic digestion, is conducive to the gas production for increasing anaerobic digestion and reduces the production for consuming biogas residue
Output, thus high-temperature-hot-water solution technology is used for the preposition pretreatment of anaerobic digestion.
Existing sludge hot hydrolysis system mainly includes intermittent pyrohydrolysis system (such as CAMBI (health is green) product), continuous vertical
Formula baffle plate pyrohydrolysis system (such as Veolia Exelys product) and hot oil tubular heating system (such as Ovivo water

For, intermittent pyrohydrolysis system includes preheating pulp tank, hot water solution reaction kettle and pressure release flash tank, and main flow includes will
Dry solid content is pumped into preheating pulp tank for the dewatered sludge of 16-18% and is preheated to 90-100 DEG C, and it is anti-to be then pumped into pyrohydrolysis
It answers kettle to be heated to 165 DEG C, and reacts at this temperature 20-30 minutes, sludge is sent into the cooling of pressure release flash tank after the reaction was completed
To 100 DEG C, temperature needed for continuing cool to anaerobic digestion later.But intermittent pyrohydrolysis system and technique there are still with
Lower shortcoming: it is passed through steam preheating in the preheating pulp tank of big volume, since dewatered sludge dry solid is at concentrations up to 16-
18%, being heated evenly property of sludge is poor in heating process, and heat transfer efficiency is low, so as to cause heating the time required to long, steam consumption

Increase the manufacture and operating cost of equipment.It can be seen that equipment employed in existing high-temperature-hot-water solution technology is in processing Gao Gu
Generally existing following problems when body content sludge: heat-transfer effect is poor, material uneven heating is even, steam consumption is big, heating time is long,
It is poor to operate continuously stability, and thus leads to equipment input cost height, processing cost height, poor processing effect.In addition,
The biological sludges such as activated sludge are pre-processed using existing high-temperature-hot-water solution equipment and technique in actual application, then
High-temperature-hot-water solution treated product is subjected to anaerobic digestion, whole gas production can not be significantly improved, this is primarily due to existing
There are pyrohydrolysis equipment and technique to be difficult to the hardly degraded organic substance in the biological sludges such as hydrolysing activity sludge, and these are difficult to degrade organic
Object is difficult to effectively degrade in existing anaerobic digestion process, so as to cause the reduction of anaerobic digestion rate, imitates the degradation of anaerobic digestion
Fruit and whole gas production are bad.The presence of the above problem limits the application effect and application range of anaerobic digestion techniques, very
Be unfavorable for biological sludge be effectively treated and recycling recycle, the due value of biological sludge can not be played.Therefore, such as
What, which is effectively improved the above problem, obtains that a kind of heat-transfer effect is good, being heated evenly property of material is good, steam consumption is small, heating time
