Description
SPECIFICATION
Cleaning waste gases
The present invention relates to a method of cleaning waste gases from destruction plants for dealing with industrial and household waste from toxic chlorine compounds and/or heavier hydrocarbons, and to a plant for performing the method according to the invention.
Conventional incinerators for household and industrial waste have been found to give off not inconsiderable quantities of substances injurious to health in the form of chlorine compounds, for instance, dioxines. These compounds are produced in the combustion chamber due to low combustion temperatures occurring locally. They may also be produced when the exhaust gases are cooled if the gases contain chlorine and/or hydrogen chloride.
As yet there is no suitable method of ensuring that such chlorine compounds are not formed, nor is there any method of removing them from the exhaust gases coming from these types of destruction plants.
One object of the invention is to effect a method of cleaning waste gases from destruction plants for industrial and household waste, which ensures that the gases do not contain toxic chlorine compounds.
Another object of the invention is to achieve a cleaning process which also eliminates the content of heavier hydrocarbons such as tar and the like.
Yet another object of the invention is to produce a plant for performing the method according to the invention.
The method according to the invention is characterised in that chlorine compounds occurring in the waste gases are decomposed by means of irradiation with UV light in a cracking chamber and in that heavier hydrocarbons occurring in the waste gases are simultaneously cracked by supplying external thermal energy, independent of the combustion.
According to one embodiment of the invention, the UV irradiation is effected by conducting a part of the gases through an electric arc generated in the cracking chamber to heat parts of the gas flow to ionization temperature while at the same time increasing the physical heat content of the gases.
According to another embodiment of the invention the UV irradiation is effected by conducting the waste gases througha chamber into which a gas heated to ionization temperature in a plasma generator is introduced.
Treatment with plasma gas, either generated by transferred arc, i.e. by an arc generated in the chamber, or by the use of a plasma generator, causes heating of the gases in the chamber, the physical thermal content in the gases being utilized to crack any heavier hydrocarbons, such as tar, present in the waste gases from the furnace.
The waste gases are suitably introduced tangentially into the cracking chamber and are caused to rotate so that uniform irradiation of the entire quantity of gas flowing through is obtained.
To prevent dioxines being re-formed, for instance, or the formation of other toxic chlorine compounds, a second process step may be performed according to the invention in which the cleaning gases after cooling, e.g. by heat-e#chang- ing to 350-700 C, are introduced into a reactor filled with a suitable acceptor for removing chlorine and/or hydrogen chloride from the gas, as well as for condensing any metal vapour in the gas.
Quicklime or slaked lime and/or dolomite is/are preferably used as acceptor.
In destruction plants operating with a deficiency of oxygen, according to the present invention the waste gases may be subjected to a carburizing step after irradiation, whereupon the gas is caused to pass a reactor filled with solid carbonaceous material in lump form, e.g. coke, possibly with an additive such as an alkali compound to increase the reactivity. The physical heat of the gas is then utilized to heat the coke to the temperature of the gas, the carbon in the coke reacting with oxygen, carbon dioxide and water vapour in the gas, to form carbon monoxide and hydrogen gas, thus increasing the thermal value of the gas.
The plant for performing the method according to the invention includes a furnace for the destruction of industrial and household waste and conventional means for heat exchanging, cleaning and cooling, and comprises a cracking chamber, preferably heat-insulated, containing a source for UV irradiation as well as a source for the supply of thermal energy.
The cracking chamber is preferably designed as a heat-insulated reactor into which the waste gases are conducted tangentially and pass through the chamber in a rotary movement along the wall to the outlet at the opposite end of the chamber.
According to one embodiment of the invention the source of UV irradiation and the supply of thermal energy consist of two electrodes inserted in the chamber, between which an electric arc is generated inside the chamber, through which a part of waste gases is caused to flow.
According to an alternative embodiment of the plant according to the invention, the source of UV irradiation and supply of thermal energy consists of at least one plasma generator arranged in the immediate vicinity of the cracking chamber, in which plasma generator a gas flow is heated to ionization temperature in an electric arc generated between two electrodes in the plasma generator, said ionized gas being subsequently introduced into the chamber.
According to another embodiment of the invention, the plant includes a carburizing shaft filled with coke, arranged immediately after the cracking chamber.
According to yet another embodiment of the invention, the plant includes a reactor filled with a suitable acceptor for chlorine and and/or hydrogen chloride in the gas. The acceptor preferably consists of quicklime or slaked lime and/or dolomite.
The reactor preferably consists of a vertical shaft with supply means for the acceptor at its top and tapping means for removal of the products ab sorbed.
Further advantages and features of the invention will be revealed in the following detailed description with reference to the accompanying drawing, in which
Figure 1 shows schematically an waste-destruction plant according to the invention,
Figure 2 shows schematically an alternative embodiment of a waste-destruction plant according to the invention,
Figure 3 shows schematically a cracking chamber operating in accordance with one embodiment of the invention, in combination with a carburizing shaft, and
Figure 4 shows schematically a cracking chamber operating in accordance with an alternative embodiment of the invention, in combination with a carburizing shaft.
The plant shown schematically in Figure 1 comprises an incinerator 1 operating with an excess of oxygen, i.e. pure combustion. The waste gases are conducted to a cracking chamber 2, to be described in more detail below, in which the chlorine compounds injurious to health which occur in the gas are cracked by means of UV irradiation. Heavier hydrocarbons are disintegrated by the thermal energy supplied simultaneously.
The scrubbed gases are then suitably conducted from the cracking chamber, possibly after chlorine scrubbing which is described in more detail with reference to Figure 2, to a heat-exchanger 3, a scrubbing and cooling means 4 and are then discharged from a chimney 5. These steps represent conventional technology and will not be dealt with further here.
The plant shown schematically in Figure 2 comprises a destruction plant 10 which utilizes oxygen deficiency and can thus be used for the production of combustible gases. The waste gases are conducted from the furnace to a cracking chamber 11 of the same type as indicated above, which will be described more fully below. The gas from the cracking chamber 11 is conducted into a carburizing shaft 12 arranged immediately thereafter, in which the thermal value of the gas is increased by making use of its physical thermal content.
The gas is carried from the carburizing shaft via a cooler or heat-exchanger 13, in which the temperature is reduced to a temperature of ca. 350 700 C, to a chloride scrubbing unit 14 in which chlorine and/or hydrogen chloride in the gases are removed by means of an acceptor in the form of quicklime or slaked lime andlor dolomite.
The gas thus cleaned and improved in quality can then be caused to pass conventional treating units or may be withdrawn for combustion or some other application.
Figure 3 shows a cracking chamber 30 arranged in conjunction with a carburizing shaft 31. It should be noted that the cracking chamber in the plant shown in Figure 1 operates separately and that a carburizing shaft is not obligatory. The same of course applies to the embodiment of the cracking chamber shown in Figure 4.
In the embodiment shown in Figure 3 the cracking chamber according to the invention is designed as a reactor with a tangential inlet 32 for the waste gases from the combustion furnace. The chamber contains a bottom electrode 33 and an annular electrode 34, between which an electrode arc 35 is generated. Upon passage through the arc a small part of the waste gases will achieve ionization temperature and will therefore emit UV radiation.
Since the waste gases flow with a rotary movement, they will be uniformly and completely irradiated.
The physical thermal content of the gas is further increased in the cracking chamber by the electric energy supplied, enabling the thermal content to be utilized in the subsequent carburizing step. The carburizing shaft 31 comprises a coke inlet 36 at the top and an outlet 37 for remaining products at the bottom. The waste gases are introduced at the bottom of the reactor and discharged through an upper gas outlet 38.
The coke filler in the shaft is heated to the temperature of the gas by the physical thermal content of the gas and oxygen, carbon dioxide and water vapour are converted with the carbon in the coke to carbon monoxide and hydrogen gas. After this the gas may be cleaned from sulphur in conventional manner if required.
After said sulphur purification, if any, the gas is cooled or heat-exchanged to approximately 350 700 C and passed through a suitable acceptor for chlorine and hydrogen chloride, suitably quicklime or slaked lime and/or dolomite. A vertical reactor filled with the acceptor is advantageously used.
Figure 4, like Figure 3, shows a cracking chamber 40 arranged in immediate conjunction with a carburizing shaft 41. A gas, suitably a single-atom gas, is supplied to a plasma generator 42 and heated to ionization temperature in an electric arc generated therein. The gas thus heated is introduced into the cracking chamber 40 at 43 while the waste gas is introduced tangentially through inlet 44 and is thus irradiated by the UV radiation emitted by the plasma gas. At the same time, the waste gases are heated at least slightly by the hot plasma gas and this heat can then be used as before in the carburizing shaft. The quantity of heat added in this way can per se also be controlled.
