Reach the multipurpose for reducing Waste volume, eliminating poisonous and harmful substance, reclaim available energy and environmental protection.
For the incineration treatment technology of petrochemical industry solid waste, situations below is presently, there are:
1)Burn dyestuff and adopt fuel oil, such as《Petrochemical industry environmental protection》(" brief talk is by the burning disposal of chemical industry waste
Technology ", the 1st phase of volume 26 in 2003,43-44), as petroleum resources are nervous, the use of fuel oil must cause production fortune
Row high cost, the situation of the wasting of resources occur, and are unfavorable for the sustainable development of the energy;
2)A large amount of petrochemical industry solid wastes, such as:Waste liquid, solid slag, body refuse etc. are admitted to incinerator, which are entered using high temperature
Row is burned, and the burning of burning process sinopec solid waste is uneven, can cause the reduction of efficiency of combustion, cause incinerator tail gas
The excess of middle CO, affects the processing pressure of tail gas.
Existing patent document CN103386413A(A kind of garbage combustion device and method, 2013-11-13)Propose one kind
Including the garbage combustion device of broken coal delivery unit, powder unit processed, pulverized coal conveying unit and waste incineration unit, by original rubbish
Rubbish burning fuel oil replaces with coal, is burnt away the refuse using coal dust, preferably solve due to China's oil resource scarcity and
The problems such as burning high cost that causes, raw material obtain difficult, significantly reduces the cost of garbage disposal and to narrow resources
Utilize.
Existing patent document CN104482548A(A kind of efficient burning low pressure drop co incinerators, 2015-04-01)In burning
In device, regenerated flue gas distribution cavity, auxiliary air distribution cavity and primary air distribution cavity are set, using the vertical tube structure being obliquely installed,
Auxiliary air, regenerated flue gas incision regenerated flue gas rotary flow device is made, the kinetic energy of regenerator flue gas is made full use of, when reducing rotation
Droop loss, increase flue gas eddy flow, so as to realize the abundant burning of flue gas.
Utility model content
The purpose of this utility model is to provide the coal-fired incinerator for petroleum industry discarded object, is substituted using coal dust
Fuel oil is burnt, and decapacitation reduces outside industrial cost, by the use of tail gas as coal dust pumped (conveying) medium, moreover it is possible to carried in tail gas
Pollutant is burnt again, reduces tail gas pollution degree;Oxygen-enriched obtained in PSA adsorbent equipments being conducive to is passed through in intermediate zone
Second-time burning abundant, it is to avoid primary combustion zone because burn insufficient and carries the pollutants such as CO, NO entrance intermediate zone, enter
One step improves the efficiency of combustion of incinerator, reduces the purification pressure of tail gas from incinerator.
The utility model is achieved through the following technical solutions:For the coal-fired incinerator of petroleum industry discarded object, including
Incinerator, is equipped with coal powder entrance on incinerator primary combustion zone and intermediate zone, the coal powder entrance connection closing
Coal dust channel, sets communicating pipe between tail gas from incinerator outlet and coal dust channel, sets air blast within the communicating pipe;In incinerator
The secondary air inlet of intermediate zone sets PSA adsorbent equipments, and Secondary Air sends into incinerator second-time burning after PSA adsorbent equipments
Area.
Deflector is set in the incinerator inner wall, the deflector is located at the top of primary combustion zone, and is inclined at and is burnt
Burn stove inwall.
The deflector is in 45 ° with the angle of incinerator inner wall.
The deflector arranges multilayer along incinerator inner wall annular, on the deflector sets pod apertures.
The utility model compared with prior art, with advantages below and beneficial effect:
(1)The utility model is passed through oxygen-enriched obtained in PSA adsorbent equipments in intermediate zone, is fully burnt, it is to avoid
Primary combustion zone carries the pollutants such as CO, NO and enters intermediate zone because burning insufficient, further improves the combustion of incinerator
Efficiency is burnt, reduces the purification pressure of tail gas from incinerator.
(2)The utility model mentions the fuel oil that is related in prior art as the burning fuel of incinerator using coal dust,
On the one hand, industrial cost can be reduced, on the other hand, conveying power is used as by tail gas coal dust is sent into incinerator, moreover it is possible to tail
The pollutant carried in gas is burnt again, is reduced tail gas pollution degree, simultaneously as tail gas has high temperature, can be improved burning
The ignition temperature of stove, improves efficiency of combustion.
(3)Design of the utility model using deflector, the flue gas that produce can primary combustion zone are entering second-time burning
