The present invention relates to a water seal chamber device for condensed water generated in the flue gas stack of an activated carbon regeneration furnace, and to obtain the vibration effect and expansion tube replacement effect of a manned blower.

In general, the exhaust gas containing harmful components and dust generated in the process of regenerating waste activated carbon in the activated carbon regeneration furnace is cooled in a cooler and a wet precipitator after secondary combustion in a reburner, and after removing dust, a manned blower By means of exhaust through the stack to the atmosphere.

That is, in the conventional exhaust system related to the above technology, as shown in FIG. 1, the exhaust gas passing through the cooler cools the exhaust gas containing a large amount of high temperature and dust while passing through the wet dust collector 1 installed on one side. After the dust is collected, it is discharged into the atmosphere by the blower 3 along the suction duct 2 through the lead duct 4 and the stack 5.

At this time, expansion pipes (6a) and (6b) are connected to the connection between the attracting blower (3) and the suction duct (2) and between the discharge duct (4) and the flue (5), respectively. The valve 7 and the drain pipe 8 were comprised.

However, the exhaust gas discharged through the path is condensed water is generated by the temperature difference of the flue (5), the condensate is dust and harmful substances, such as SOX, NOX, etc. that are not completely removed from the wet dust collector (2) Since it contains a large amount of dust, the drain valve 7 and the drain pipe 8 below the flue 5 are blocked, so that the condensed water cannot be drained and accumulated under the flue 5, and is discharged through the discharge duct 4 Backflow to (3), the backflow condensate is attached to the impeller (impeller) of the manned blower (3) to cause the vibration and imbalance of the fan to damage the discharge side expansion pipe (6b), discharge duct (4) as well as It is disadvantageous to stop the operation of the activated carbon regeneration furnace by preventing the manned blower 3 from operating.

In addition, the condensed water generated by the temperature difference between the discharge duct 4 and the flue 5 outside air flows directly into the manned blower 3 because there is no discharge pipe, thereby increasing the failure of the manned blower 3. The surface of the discharge duct (4) and the flue (5) has a number of problems, such as corrosion due to the accumulated condensed water is promoted to form a pore, resulting in environmental pollution due to leakage of the exhaust gas.

The present invention has been made to improve the above-mentioned problems, and its object is to provide a water seal chamber having a partition wall formed at the rear end of an induced blower for sucking and discharging exhaust gas from an activated carbon regeneration furnace, and the bottom side thereof. By installing a condensate outlet hole so that the condensate generated in the flue is easily discharged into the drain pipe, the condensate generated in the stack (Stack) can be efficiently recovered and drained to prevent the blockage and corrosion of the flue, as well as the condensate Maximize the efficiency of the manned blower by preventing the backflow of the manned blower in advance, and by eliminating the discharge duct and the expansion tube according to the conventional method, the manned blower is directly spoken in the year, simplifying the equipment and vibrating the manned blower. It is to provide a water seal chamber device to prevent the back.

Hereinafter, a preferred embodiment of the present invention based on the accompanying drawings.

2 is a block diagram showing the exhaust system of the activated carbon regeneration furnace in which the water seal chamber device according to the present invention is installed, and FIG. 3 is a front sectional view of the main part of the present invention showing the internal structure of the water seal chamber device. A wet dust collector 1 is installed to cool and collect dust and exhaust gas, and one end of the induction blower 3 is connected to the flue 5. The water seal chamber 10 is mounted between the manned blower 3 and the flue 5, and the rear flange portion of the manned blower 3 and the front flange portion of the water seal chamber 10 are bolted (not shown). And a partition wall 11 and an outer wall 10b are formed on an outer circumferential side of the inner wall 10a at an upper portion of the water seal chamber 10. The partition 11 has a height lower than that of the outer wall 10b and the inner wall 10a, and the partition wall 11 and the outer wall of the lower plate 10c formed from the lower end of the outer wall 10b to the outer circumferential surface of the inner wall 10a. Between the 10b, there is a drain pipe 14 with a drain valve 13 and an outflow hole 12 extending. A fresh water supply path 16 is installed to penetrate the outer wall 10b and the partition wall 11 to supply fresh water between the partition wall 11 and the inner wall 10a. The partition wall 11 and the inner wall 10a are also provided. The flue 5 is formed in between.

In addition, a cover 15 for covering the water seal chamber 10 is provided on the outer circumferential side of the flue 5.

In the figure, reference numeral "W" denotes condensate generated in the year (5).

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

As shown in FIG. 2 and FIG. 3, the exhaust gas passing through the cooler cools and dusts are removed from the wet dust collector 1, and the flue (5) is passed through an induction blower (3) installed behind the suction duct (2). When discharged to the condensate (W) generated by the temperature difference with the outside is collected in the water seal chamber 10 installed at the rear end of the manned blower (3), the condensate (W) at this time is a large amount of molecules ( Dust) and harmful substances, so that fresh water is supplied through the fresh water supply passage 16 spoken to the upper side of the water seal chamber 10 to dilute it.

Then, as shown in FIG. 3 by the partition wall 11 provided in the water seal chamber 10, a large amount of dust is collected, and the drain valve through the condensate outlet 12 installed in the bottom. By being discharged to the outside by the 13 and the drain pipe 14, the phenomenon that the drain valve 13 and the drain pipe 14 are blocked by the dust can be prevented in advance.

In addition, the vibration generated in the manned blower 3 is attenuated by the condensed water W and the supplied fresh water in the water seal chamber 10 so that the vibration is not transmitted to the flue 5.

As described above, according to the water seal chamber device of the present invention, a water seal chamber having a partition wall is installed at the rear end of a manned blower that sucks and discharges the exhaust gas of the activated carbon regeneration furnace, and a condensate outlet hole is installed at one side of the bottom. By easily discharging condensate generated in the flue into the drain pipe, the condensate generated in the flue can be efficiently recovered and drained to prevent clogging and corrosion of the flue and drain pipe, as well as to prevent the condensate from being returned to the manned blower. It prevents the failure of the manned blower, prevents the failure of the manned blower, maximizes its efficiency, and eliminates the discharge duct and the expansion tube according to the conventional method, so that the manned blower is delivered directly to the year, thereby simplifying the equipment and vibrating the manned blower. It is to have an effect that can prevent.
