Technical field
It the utility model is related to oily sludge Non-oxygen pyrolytic and energy conservation field, more particularly to a kind of oily sludge
From heat supply Non-oxygen pyrolytic equipment.
Background technology
Oiliness sludge (especially sludge caused by Oil-production Enterprises, oil refining enterprise, coal chemical enterprise etc.) typically containing oils~
50% (wt), aqueous~5% (wt), slag class~45% (wt)；Its Main physical property is：Volume is big, and viscosity is big, grease boiling point
It is high, not volatile etc..
Existing oily sludge more using drying equipment handle, it is dried~100 DEG C containing smelly high humidity part tail gas more using rotation
The laggard boiler of wind separator dedusting discharges after burning deodorization, and this technological advantage is to accomplish that oily sludge minimizing is handled, and shortcoming is：
1. boiler generates~500 DEG C of high-temp waste gas after burning deodorization, its exhaust-gas treatment has 3 kinds of modes, first, air is directly discharged, two
It is that cold medium (such as air, process water) recovery heat, but the exhaust temperature of high-temp waste gas are heated using indirect heat exchanger
At~200 DEG C, third, using~20 DEG C of direct spraying coolings of process water, waste gas exhaust temperature can be controlled in~60 DEG C, but produces
A large amount of~60 DEG C of oily waste waters, this 3 kinds of mode all easily produce secondary pollution to environment；2. dried~100 DEG C of high humiditys contain
Smelly tail gas, which enters boiler burning, needs fuel (such as coal, oil, natural gas) to provide the heat required for burning, and does not save.
Utility model content

Middle Non-oxygen pyrolytic oil-containing wet mud evaporates oil gas, whole high temperature gas phase formed it is closed circulated from lazy formula ,~150 DEG C of oil gas and~
500 DEG C of high-temperature flue gas are hardly outer to be arranged.And the combustion-supporting air quantity needed when needing the exhaust gas volumn of outer row to be burned equivalent to oil gas, this
Partial fume amount only accounts for the 5~10% of circulating flow rate, and waste gas discharge capacity is small, while even if need the flue gas discharged, and in batch mixing
Emptied in the chuck of conveyer after Btu utilization cooling, alkali liquor absorption, charcoal absorption deodorization, to environment without primary pollution and two
Secondary pollution, environmental protection.
Waste water：Produced in the utility model without waste water.
It is useless solid：Oil-containing wet mud forms solid slag, body in swinging pyrolysis oven in the utility model after Non-oxygen pyrolytic
Product reduces, and has accomplished minimizing；Solid slag contains calorific value simultaneously, and burning can be mixed with coal dust, has accomplished recycling.
(3) heat integration utilizes
The combustion air of direct combustion incinerator is the air-flow conveying air after being exchanged heat with waste residue in the utility model, and it is warm
Degree can be from~20 DEG C of heat exchange to~60 DEG C；Oil-containing wet mud carries heat indirectly heat using flue gas is discharged in batch mixing conveyer,
Its temperature can be from~20 DEG C of heat exchange to~100 DEG C；It is comprehensively utilized heat.
(4) solves viscous wall using returning charge
In the utility model in batch mixing conveyer, conveyed using air-flow, after~20% pyrolysis is blended in oil-containing wet mud
Waste residue, reduce moisture content while, can effectively solve the problems, such as in swinging pyrolysis oven glue wall.
(5) anaerobic sealing and circulating, system safety
Whole technical process is carried out in the system of high-temperature flue gas sealing and circulating in the utility model, and this system is equivalent to lazy
Property confined gas circulating system, making the preheating, pyrolysis and oil gas of oiliness sludge, to burn etc. carried out in oxygen-free environment, is
System safety.
