The present invention is a coke oven gas cooling ordination pump filtration that can easily remove the coke lumps and other foreign matter contained in the ordination to cool the coke oven gas at the coke oven outlet in the ordination circulation pump Relates to a device.

In general, the ordination circulation pump is a device for cooling a high temperature coke oven gas of about 800 ℃ generated in the coke oven to about 80 ℃.

Coke lumps and other foreign substances are easily introduced into the cooling water circulating in the ordination circulation pump, and NH _{3 is} also contained in a large amount, so the tar component contained in the coke oven gas is cooled in the separator when the coke oven gas is cooled. Some tar and coke lumps and other substances that could not be separated by the car are introduced into the ordinal pump.

On the other hand, in the conventional water pump structure as shown in Figs. 1 and 2, the water inlet 12a and the water outlet 12b are formed on the left and right sides of the eye pump filtration apparatus 11, and there are holes in the interior. A strainer 14 having a number of perforations (13) is installed vertically, a cover 15 is provided on an upper side of the ordinal pump filtration unit 11, and a hole 16 is formed on the bottom thereof, It is made of a structure connected to the drain valve (17).

The conventional ordination circulation pump filtration device configured as described above is filtered through the ordination inlet 12a by a strainer 14 vertically placed in the filtration device 11 in a size of about 60 × 80 cm. The coke lumps and other foreign matters are filtered out of the ordinal water flowing into the apparatus 11 and then discharged through the ordinal outlet 12b.

However, since the strainer 14 installed in the filtering device 11 is formed in a rectangular shape, foreign matters are easily attached, and when the foreign matters are attached, the suction area of the ordination is drastically reduced, as well as the strainer 14. Since the perforated hole 13 has a diameter of about 1.5 mm, the coke lump having a larger diameter easily closes the hole 13, so that the effect of filtration is greatly reduced.

In addition, since the cover 15 is fixed to the upper side of the filtration device 11 by the bolt (B), not only can not be confirmed when backwashing, but also the coke lumps and foreign substances are discharged through the holes 16 formed at the bottom during backwashing. It should be, but the hole 16 is narrow, the foreign matter remains in the filtration device 11, there is a problem that causes the occurrence of a safety accident due to toxic gas and pollute the environment during the internal cleaning operation to remove this. .

In addition, the holes 11 drilled in the strainer 14 are too large in diameter (1.5 mm), resulting in fine coke lumps being included in the ordination to block the spray nozzles, resulting in a load on the coke manufacturing process. There was a problem.

The present invention was devised to improve the general conditions and problems as described above, the purpose of which is to provide a wall space formed by bending the both ends of the elliptical strainer, the upper side of the filtration device for cleaning steam pipe While a check hole is opened and closed by a handle to the upper side of the cover, the bottom part is provided with a drain port where a part is cut and foreign matters can be collected. Accumulated through the space portion to be naturally settled, it can be easily removed through the drain port, as well as to reduce the diameter of the hole formed in the strainer to prevent clogging of the spray nozzle by ordination mixed with foreign matter, and In case of closing, use cleaning state through check hole after back washing. In particular, residues that are not sedimented naturally stuck to the strainer are sprayed with steam or high pressure air by a cleaning steam tube installed in the upper part of the cover, and the coke oven gas cooling ordination can easily remove and remove the residues. To provide a pump filtration device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a structural diagram showing a coke oven gas cooling ophthalmic pump filtration apparatus according to the present invention, and FIG. 4 is a view showing a strainer installed in the ophthalmic pump filtration device of the present invention. Left and right, the ordination inlet (2a) and the ordination outlet (2b) is spoken, the strainer (4) is installed vertically therein, the drain valve (7) is connected to the bottom of the ordination pump filtration device (1) In the elliptical shape, the wall spaces 6a and 6b, which are bent, are provided at both end portions of the strainer 4, which are formed in an elliptical shape, and the holes 3 are perforated, respectively. A confirmation port 9b for opening and closing by the handle 9a is installed at an upper side of the cover 5 in which the steam pipe 8 is extended, while a drain port 10 in which a part is cut off and foreign matters can be collected. ) Installed drain valve (7 ), Which is composed in speech.

In the figure, reference numeral H denotes a handle for opening and closing the drain valve 7.

Referring to the operation and effects of the present invention made of such a configuration as follows.

As shown in FIG. 3 and FIG. 4, since the strainer 4 installed at the inlet of the ordination circulation pump filtration device 1 is made into an elliptical shape, the strainer 4 is introduced into the front of the strainer 4 through the ordination inlet 2a. As the ordination passes through the ordination through the hole 3 by the suction force, foreign matter is momentarily hit by the strainer 4 and slipped and accumulated in the wall space portions 6a and 6b which are bent at both ends, and the specific gravity with the ordination The coke mass and the foreign matter settled to the bottom by the bottom, the bottom of the water pump filtration device (1) is cut off and collected in the drain port (10) rounded above the drain valve (7), and then the drain valve (7) is opened. Easily discharged.

On the other hand, by making the shape of the strainer 4 elliptical as described above, the suction area of the ordination becomes larger than that of the conventional rectangular strainer, so that the rated capacity of the ordination circulation pump can be maintained, and the closing period of the strainer 4 is extended. Coke lumps and foreign matter can be easily removed as described above to reduce the diameter (1 mm) of the hole (3) perforated in the front of the strainer (4), thereby preventing clogging of the spray nozzle.

In addition, when the strainer 4 is closed, the cleaning state can be easily confirmed through a check hole 9b installed on the upper side after backwashing. By allowing high pressure steam or air to be injected through the cleaning steam tube 8 installed at the upper portion thereof, the residue adhering to the strainer 4 can be easily separated and removed.

As described above, according to the coke oven gas cooling ordination pump filtration device of the present invention, the coke lumps and foreign substances mixed in the ordination are accumulated through the wall space portion by the suction wall to naturally settle, and thus easily through the drain port. In addition, the diameter of the hole formed in the strainer can be reduced to prevent clogging of the spray nozzle by the ordinal mixed with foreign substances, and the cleaning state can be easily checked through the check hole after backwashing when the strainer is closed. Residue that is not sedimented on the strainer by spontaneous sedimentation has an effect of easily discharging and removing the residue by spraying steam or high pressure air by a cleaning steam tube installed on the cover.
