Abstract
The system and method for burning organic compound is mixed the invention discloses a kind of pulverized-coal fired boiler, the system includes pretreatment system, combustion system, atomization system, purging exchange system, the steady combustion system composition of material, by effective combination of several big systems, abundant, stable burning of the organic compound in coal-powder boiler ensure that.In the flow for mixing burning, the organic compound in the external world is set to require to carry out pressure regulation according to the minimum atomization of atomizing gun, simultaneously by filtering decontamination, it is atomized into atomizing gun, atomizing type is based on mechanical atomization, while subsidiary medium atomization, and the organic compound through being fully atomized, which is sprayed into stove, to be burnt, gun head adds steady combustion cover, the disturbance of disturbance and boiler combustion wind when reducing medium atomization.The present invention solves the place to go of chemical enterprise organic liquid waste, reduces the operation expense of special disposal waste liquid, while reclaims organic compound heat, really realizes energy-saving and emission-reduction.
Description
Technical field
The invention belongs to Boiler Mixed Burning recovery technology field, and in particular to a kind of pulverized-coal fired boiler, which is mixed, to be burnt organic compound and be
System and method.
Background technology
During coal chemical industry enterprises produce final material, portion, waste liquid etc. will necessarily be produced, with energy-conserving and environment-protective
It is required that it is increasingly strict, waste gas, waste liquid need be disposed properly.At present, in coal-burning boiler tradition blending and burning technology, no matter burn gas, go back
It is to burn liquid fuel, generally existing burning is insufficient, medium atomization is bad, burning coking easily occurs in heating surface region, influences master
The problems such as wanting fuel combustion operating mode, the appearance of these problems, mainly co-combustion system, which are set, has some problems, particularly medium
Atomization system, the equal existing defects of atomizing angle, jet length, and meanwhile it is also unreasonable with main fuel spout line space design.
The content of the invention
An object of the present invention is to provide a kind of pulverized-coal fired boiler and mixes the system for burning organic compound, and the system can guarantee that
Abundant, stable burning of the machine compound in coal-powder boiler.
The second object of the present invention is the method that Boiler Mixed Burning recovery is realized with said system, solves chemical enterprise organic waste
The place to go of liquid, reduces the operation expense of special disposal waste liquid, while reclaims organic compound heat, really realizes that energy-conservation subtracts
Row.
To achieve these goals, the technical solution adopted in the present invention is：A kind of pulverized-coal fired boiler mixes burning organic compound
System, the pretreatment system of the system including material, atomization system, combustion system, purging exchange system, surely fire system.
Described pretreatment system is made up of voltage regulating station and dirt separator, and is connected by pipeline with flange；Described combustion system is
It is made up of sleeve pipe and cooling air compartment and repid cut-off valve, sleeve pipe is welded as a whole with cooling air compartment；Described atomization system be by
Atomizing gun and nozzle and assisted atomization wind composition, with nozzle using being threadedly coupled, assisted atomization wind draws atomizing gun for welded pipe line
Enter；Described purging exchange system is made up of compressed air, purging nitrogen, is formed by pipeline welding；Described steady combustion system
System is to be welded and fixed by steady combustion cover with cooling air compartment.
The present invention realizes that a kind of system described in claim 1 realizes that pulverized-coal fired boiler mixes burning organic compound with said system
Method, be by organic compound caused by chemical system, Can Shao pretreatment systems voltage regulating station be first pumped to by pipeline, through pressure
Power is 1.5MPa, and for temperature to make organic compound enter dirt separator after 40 DEG C of adjustment, the organic compound after decontamination passes through metal
Flexible pipe enters co-combustion system atomizing gun, and atomizing type is based on mechanical atomization, while subsidiary medium atomization, has through what is be fully atomized
Machine compound, which is sprayed into stove, is burnt.
The beneficial effects of the invention are as follows：By effective combination of several big systems, first, ensure that organic compound in coal dust
It is stable that burning is mixed in stove, is not interfere with each other with coal dust firing；Second, atomization is good, big drop will not be formed it is directly entered burner hearth and glue
Connect, coking etc.；Third, reduce boiler coal consumption, C H compounds burning after it is pollution-free, it is economic and environment-friendly.
