Device for eliminating particulates in exhaust gas and method for eliminating the particulates

The present invention provides a PCB decomposing apparatus capable of decomposing PCB efficiently. The PCB decomposing apparatus comprises a PCB extracting container for extracting PCB from a PCB-containing material with an organic solvent. A distilling tower provided on the downstream side of the PCB extracting container distills the organic solvent to separate the PCB. A primary reactor provided on the downstream side of the distilling tower includes a nozzle for supplying aqueous Na CO solution and a nozzle for supplying an oxidizing agent into the container. A liquid cyclone provided on the downstream side of the primary reactor can remove Na CO having a large particle size. A secondary reactor formed by a long pipe is connected to the liquid cyclone. A gas-liquid separator provided on the further downstream side of the secondary reactor can separate a gas from a solution. A film separator separates treated water into purified water and a concentrated solution, and the purified water is supplied as circulating water to the upstream side of a pressure pump.

Apparatus for decomposing PCB

CaS oxidation has CaS particles oxidized into CaSO completely as far as to the interior of the particle. The interior of an oxidation apparatus is partially partitioned by a partition to thereby form a first fluidized bed on the inner side, a second fluidized bed on the outer side and a space portion thereabove. A heat exchanger having a baffle plate is disposed on the inner side of the partition and an in-bed heat exchanger is disposed on the outer side of same. A desulfurizing product-containing fine powder and coarse powder and a mixture gas of nitrogen, oxygen and steam are supplied into the second fluidized bed . Also, coal and coal char are supplied into the first fluidized bed from below. Of the particles oxidized in the second fluidized bed and supplied into the first fluidized bed from below with the flow of a mixture gas , the fine powder entrains into the space portion as entrained particles and a major part thereof falls down into the second fluidized bed as particles . The completely oxidized particles are discharged as discharged ash and entrained ash

Method for decomposing PCB

This invention relates to a PCB decomposition process which comprises the steps of reacting an organic material with sodium hydroxide to form sodium carbonate, and decomposing PCB with the aid of the sodium carbonate so formed.

PCB decomposition process

In a coal gasification power generator, coal gas 500 obtained by gasifying a coal 100 by a gasifying furnace is introduced into a desulfurization furnace in which the coal gas 500 is desulfurized by limestone 400. A coal gas 501 after desulfurization is burned by a combuster 5 after it has passed through a dust removing unit 3 so that high temperature combustion gas 800 is supplied to a gas turbine. The gas turbine 7 drives a power generating unit. Exhaust gas 801 from the gas turbine is supplied to an exhaust gas boiler 8. Char 60a produced in the gasifying furnace and limestone 60b containing CaS emitted from the desulfurization furnace are burned in an oxidation furnace, and by using the resultant combustion gas, water vapor introduced from the exhaust gas boiler 8 is heated by a heat exchanger, and thereafter it is supplied to the gasifying furnace as a gas. With the above construction, chemical energy possessed by the coal is effectively converted into electric energy, and also the rate of desulfurization of coal gasifying gas is improved thereby reducing emitted sulfur oxide.

A char 60a produced in the gasifying furnace 1 and limestone 60b containing CaS emitted from the desulfurization furnace 2 are burned in an oxidation furnace 4, and by using the resultant combustion gas, water vapor 30a introduced from the exhaust gas boiler 8 is heated by a heat exchanger 10, and thereafter it is supplied to the gasifying furnace 1 as a gas 700. With the above construction, chemical energy possessed by the coal 100 is effectively converted into electric energy, and also the rate of desulfurization of coal gasifying gas is improved thereby reducing emitted sulfur oxide.
