Description

Technical Field

[0001] The utility model relates to the technical field of discharge tower equipment, in particular to an anti-clogging coke oven discharge tower structure. Background Art

[0002] The coke oven discharge tower is a safety measure taken to prevent the coke oven gas pressure from being too high. When the pressure of the raw gas collecting pipe continuously generated in the carbonization chamber exceeds 200MPA or the gas blower fails and there is a sudden power outage, the ignition and discharge system ignites and opens the discharge valve flap to pressurize the raw gas from the collecting pipe, ignite and burn, and then discharge.

[0003] The relief valve flap currently used in coking plants uses ammonia water to seal the gap in the relief valve flap. The ammonia water is usually open, and water overflows from the gap into the gas collecting pipe. The overflow surface acts as a water seal. Since the bearing part of the relief valve flap is rusted and blocked by the influence of ammonia water, it fails to open in time, resulting in direct discharge of raw coal gas, causing serious environmental pollution.

[0004] Therefore, a coke oven discharge tower structure with anti-clogging is provided to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the utility model is that the relief valve flap used in the current coking plant seals the gap of the relief valve flap through ammonia water. The ammonia water is always open, and water overflows from the gap into the gas collecting pipe. The overflow surface plays the role of a water seal. Since the bearing part of the relief valve flap is rusted and blocked by the ammonia water, it fails to open in time, resulting in direct discharge of raw coal gas, causing serious environmental pollution. Therefore, an anti-blocking coke oven relief tower structure is provided, and the anti-blocking coke oven relief tower structure includes:

[0006] A discharge tower body, wherein a discharge valve is arranged in the inner cavity of the discharge tower body, a discharge valve flap is arranged in the inner cavity of the discharge tower body installed above the discharge valve, the upper end of the discharge tower body is connected with an electric butterfly valve, the upper end of the electric butterfly valve is connected with an exhaust pipe, and also includes a filtering mechanism, one end of the filtering mechanism is connected with the discharge tower body, and the other end of the filtering mechanism is connected with a sewage discharge mechanism.

[0007] Furthermore, the filtering mechanism includes a water inlet pipe, a water pump, a water storage tank, a return pipe and a filter box, one end of the water inlet pipe is connected to the side wall of the discharge tower body on which the discharge valve flap is installed, the other end of the water inlet pipe is connected to the water pump, the water pump is connected to the water storage tank, the top of the water storage tank is connected to the return pipe, and the end of the return pipe away from the water storage tank is connected to the filter box.

[0008] Furthermore, the electric butterfly valve is a DN800 stainless steel electric butterfly valve, the electric butterfly valve is flange-connected to the discharge tower body, and the electric butterfly valve is flange-connected to the exhaust pipe.

[0009] Furthermore, a cover plate is installed on the top of the filter box, and the cover plate is detachably connected to the box body of the filter box. A filter element is detachably installed in the filter box.

[0010] Furthermore, it also includes a guide structure, which includes a guide pipe and a screw cover. The guide pipe is connected to the top of the water tank, and the end of the guide pipe away from the water tank is provided with a screw cover.

[0011] Furthermore, the sewage discharge mechanism is a sewage discharge pipe, and the sewage discharge pipe is connected to the filter box.

[0012] Furthermore, it also includes a stop valve, which is installed in the sewage pipe.

[0013] Furthermore, the relief valve flap is a stainless steel flap.

[0014] The implementation of this utility model has the following beneficial effects:

[0015] The utility model is provided with a stainless steel electric butterfly valve. After the stainless steel electric butterfly valve is installed, the relief valve flap can be moved regularly to prevent rust and inaction, and also plays a role of insurance in special situations; the utility model is also provided with a filter box with a filter element. When ammonia water enters the relief valve through a water pump and a water inlet pipe to water-seal the relief valve flap, the ammonia water will flow back to the inner cavity of the water storage tank through the reflux pipe. During the reflux process, when the ammonia water enters the inner cavity of the filter guide box and passes through the filter element horizontally, larger particulate impurities in the ammonia water cannot pass through and are intercepted on the outer wall of the filter element. They are separated from the ammonia water under the action of gravity, gradually sink and gather in the impurity collection area at the bottom of the filter box, and are discharged through the sewage pipe, thereby filtering the impurities in the ammonia water. At the same time, due to the provision of the reflux pipe, the problem of ammonia water flowing into the inner cavity of the gas collecting pipe all the time, thereby causing waste, is also solved.
