Abstract
Abstract - 13 -ABSTRACT For their wet purification, gases flowing in a line are sprayed with scrubbing liquor, the resulting mixture of gas and liquid is passed through a cyclone separator. The gas is initially sprayed in a pre-scrubbing line and the gas which contains scrubbing liquor is subsequently conducted through a substantially horizontal accelerating line having at its entrance a cross-sectional area which is 1.5 to 5 times larger than the cross-sectional area at its exit. The exit of the accelerating line communicates with the cyclone separator. Purified gas is withdrawn from the cyclone separator.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
A process for the wet purification of a gas, which is sprayed with scrubbing liquor as the gas flows in a line, whereafter the resulting gas-liquid mixture is passed through a cyclone separator and purified gas and contaminated scrubbing liquor are separately withdrawn from said separator, characterized in that the gas containing impurities is sprayed with scrubbing liquid in a pre-scrubbing line, the gas which comes from the pre-scrubbing line and contains scrubbing liquor is passed through a substantially horizontal accelerating line, which at its entrance has a cross-sectional area that is 1.5 to 8 times larger than its cross-sectional area at its exit, additional scrubbing liquor is sprayed into the gas in the accelerating line, and the gas-liquid mixture is passed from the accelerating line into the cyclone separator.
Claim 2
Dependent Claim
130 words
A process for the wet purification of a gas, which is sprayed with scrubbing liquor as the gas flows in a line, whereafter the resulting gas-liquid mixture is passed through a cyclone separator and purified gas and contaminated scrubbing liquor are separately withdrawn from said separator, characterized in that the gas containing impurities is sprayed with scrubbing liquid in a pre-scrubbing line, the gas which comes from the pre-scrubbing line and contains scrubbing liquor is passed through a substantially horizontal accelerating line, which at its entrance has a cross-sectional area that is 1.5 to 8 times larger than its cross-sectional area at its exit, additional scrubbing liquor is sprayed into the gas in the accelerating line, and the gas-liquid mixture is passed from the accelerating line into the cyclone separator.
Claim 3
Dependent Claim
26 words
A process according to claim 1, characterized in that the gas is sprayed in the accelerating line with larger liquid droplets than in the pre-scrubbing line.
Claim 4
Dependent Claim
29 words
A process according to claim 1 or 2, charac-terized in that the gas is passed through at least one spraying station in each of the pre-scrubbing and accelerating lines.
Claim 5
Dependent Claim
27 words
A process according to claim 1 or 2, charac-terized in that the accelerating line is fed with sprayed liquid at a lower rate than the prescrubbing line.
Claim 6
Independent Claim
117 words
An apparatus for the wet purification of gases, comprising a gas-conducting duct, which is provided with at least one sprayer and opens into a cyclone separator, from which purified gas and scrubbing liquor, which contains impurities, are separately withdrawn, characterized in that the gas-conducting duct consists of a pre-scrubbing duct, which is provided with at least one sprayer, and a succeeding, substantially horizontal accelerating duct, which communicates with the cyclone separator, the accelerating duct is provided with at least one sprayer and the cross-sectional area of the accelerating duct at the entrance for the gas is 1.5 to 8 times larger than the cross-sectional area of the accelerating duct at its exit leading to the cyclone separator.
Claim 7
Independent Claim
117 words
An apparatus for the wet purification of gases, comprising a gas-conducting duct, which is provided with at least one sprayer and opens into a cyclone separator, from which purified gas and scrubbing liquor, which contains impurities, are separately withdrawn, characterized in that the gas-conducting duct consists of a pre-scrubbing duct, which is provided with at least one sprayer, and a succeeding, substantially horizontal accelerating duct, which communicates with the cyclone separator, the accelerating duct is provided with at least one sprayer and the cross-sectional area of the accelerating duct at the entrance for the gas is 1.5 to 8 times larger than the cross-sectional area of the accelerating duct at its exit leading to the cyclone separator.
Claim 8
Dependent Claim
19 words
An apparatus according to claim 5, charac-terized in that the accelerating duct is provided with an outlet for liquid.
Claim 9
Dependent Claim
23 words
An apparatus according to claim 6, charac-terized in that each of the proscribing and accelerating ducts is provided with at least one sprayer.
Claim 10
Dependent Claim
30 words
An apparatus according to claim 5, 6 or 7, characterized in that the accelerating duct has a length which is 4 to 20 times the diameter of its entrance cross-section.
Claim 11
Dependent Claim
24 words
An apparatus according to claim 5, 6 or 7, characterized in that the pre-scrubbing duct is provided with at least one outlet for liquid.
