Description

Technical Field

[0001] This utility model relates to the field of construction technology for dry quenching coke boilers, and in particular to a drainage device for the outlet flue of a dry quenching coke boiler. Background Technology

[0002] Currently, during long-term operation, water inevitably accumulates in the outlet flue of dry quenching coke boilers. This water accumulation affects boiler production efficiency, leading to a decrease in thermal efficiency, hindering effective heat transfer, accelerating steel structure corrosion, shortening equipment lifespan, increasing maintenance costs, and creating safety hazards. Failure to drain the water regularly can also force boiler shutdown for maintenance. Furthermore, because the water in the outlet flue of dry quenching coke boilers cannot be automatically drained during operation, manual cleaning of the outlet flue is required during boiler maintenance, resulting in low production efficiency.

[0003] Therefore, keeping the outlet flue of the dry quenching boiler dry is an important measure to ensure the stable operation of the boiler during boiler operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a drainage device for the outlet flue of a dry quenching coke boiler, so as to achieve regular drainage and prevent a large amount of water from accumulating in the flue.

[0005] The present invention adopts the following technical solution:

[0006] A drainage device for the outlet flue of a dry quenching coke boiler includes a U-shaped bend plate. The top of the U-shaped bend plate is fixedly installed on the bottom guard plate of the outlet flue. One end of the U-shaped bend plate is welded to a square ring steel plate. The other end is connected to a drain pipe. A valve is connected to the other end of the drain pipe. A hand hole is installed on the square ring steel plate.

[0007] Preferably, the handhole door includes a handhole door steel plate and a handhole door handle. The handhole door handle is fixedly welded to the handhole door steel plate, and the handhole door steel plate is connected to the square ring steel plate by a bolt, a nut, and a washer.

[0008] Preferably, a square annular gasket is installed between the handhole door steel plate and the square annular steel plate.

[0009] Preferably, the drain pipe is connected to the valve via a flange using two bolts, two nuts, and two washers.

[0010] Preferably, a spiral wound gasket is installed between the flange and the valve.

[0011] Preferably, the drain pipe is installed at the other end of the U-shaped bend via a perforated steel plate.

[0012] Preferably, the U-shaped bend is made from a single piece of steel plate.

[0013] Preferably, the portions of the U-shaped bend plate extending outwards from both sides of the bottom liner of the outlet flue are sealed with sealing steel plates.

[0014] The beneficial effects of this utility model are: This utility model provides a simple drainage device for the outlet flue of a dry quenching coke boiler; using this drainage device facilitates regular drainage on site, simply by opening the valve, thereby improving the production efficiency of the dry quenching coke boiler, ensuring the normal operation of the boiler, and reducing the operational risks caused by boiler water accumulation.
