JOHN C. HAYES. JR... OF CHICAGO, ILLINOIS, 'ASSIGNOR TO FREYN ENGINEERING COMPANY. OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.
GAS WASHER.
Application filed September 26, 1927. Serial No. 221,907.
The present invention relates to improvements in gas washers.
More particularly the present invention relates to gas washers such as are used in blast furnace installations for washing the gas delivered from the blast furnaces before said gas is delivered to the burners. Ordinarily the gas is washed with a water spray. and one of the great difliculties in effective operation has been to secure an even distribution of the water. When the water is not well distributed there is a tendency for the gas to channel. that is to say. a greater quantity of gas will pass through the zone of lesser spray density thus cutting down very materially the efficiency of the washer. Attempts have been made to overcome this difliculty and certain of the installations have very considerable merit. However, all those arrangements with which applicant is familiar fail to completely accomplish the desired distribution of the water spray.
An object of the present invention is to provide means for distributing water in a gas washer which will avoid the channeling above referred to.
A further object is to provide an improved water distributing means for a gas washer which is simple in construction. which may be installed at small expense and which is adaptable to the gas washers as at present known and used.
A further object is to provide a gas Washer which will, without any increase in the amount of water used, effect a more complete cleaning of the gas. 4
Further objects will appear as the description proceeds.
Referring to the drawings- I Figure 1 is a vertical sectional view of the top portion of a gas washer illustrating one embodiment of the present invention.
Figure 2 is a sectional View taken along the plane indicated by the arrows 22 of Figure 1.
Figure 3 is a sectional view taken along the planes indicated by the arrows 33 of Figure 1; and
Figure 4 is a detail showing a water pipe having a plurality of nozzles which cooperates with the structure shown in the preceding figures.
Referring first to Figure 1, the numeral indicates a gas washer which is illustrated in the form of a cylinder having its axis vertically disposed. According to usual practice, the gas to be cleaned will be delivered to said washer near the bottom thereof and will be discharged through the outlet 11 at, the top thereof. Intermediate of the height of the washer 10 are a plurality of hurdle's 1212. Only one bank of hurdles is illustrated though any preferred number of banks will be used. The hurdles 12-12 may take any preferred form and no novelty is claimed for said hurdles in this application.
Located above the top bank of hurdles 12 is a checkerwork construction indicated by the numeral 13 which checkerwork construction is made up of a plurality of boards 1414 providing a series of square openings 1515 which preferably have considerable length relative to the width thereof. The checkerwork 13 preferably covers the entire cross sectional area of the washer. Located above each square opening 15 is a spray nozzle 16, which nozzles 1616 are supplied with water from the pipes 17-17 which are supplied by the central distributing pipe 18.
The structure above described has the advantage that the nozzles 1616 insure the correct distribution of the water. and in addition, the checkers tend to distribute the gas flow over the entire cross section of the washer. It will be clear that as the gas passes upwardly in the Washer it will find its,
way uniformly through the checkers or passageways 1515 and each column of gas will be treated by a spray delivered by the nozzle 16 immediately above the corresponding checker ,or opening. By reason of the elongated passageways 1515. the particles of the gas have an opportunity to cling to the walls of the checkerwork, resulting in eflicient washing. Channeling of the gas is therefore avoided, and the gas is washed with materially greater efficiency than has heretofore been the practice.
It will be noted that the spray nozzles are all located at substantially the same level. Inasmuch asthe water is obtained from a common source, a more even distribution of Water is obtained than. has been possible in certain prior practice where it has been attemped to spray gas by means of nozzles set in groups at different elevations.
Though a preferred embodiment of the present invention has been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications as fall Within the scope of the appended claim.
What is claimed is- A gas Washer comprising, in combination, a conduit for gas, hurdles Within said conduit, dividing means Within said conduit, said dividing means being'disposed in position to carry said gas after said gas has passed said hurdles, said dividing means comprising a plurality of Walls arranged in right-angular relationship with one another providing a plurality of elongated passageways uniformly distributed throughout substantially the cross sectional area of said conduit, and a nozzle located adjacent to the exit of each of said passageways for delivering Water in intimate relationship with the gas passing through each of said passageways.
