Description

Technical Field

[0001] This utility model belongs to the technical field of coal charging and coke pushing in coking plants and flue gas purification at the coke side furnace head, specifically involving a water seal device with spark capture and cooling functions. Background Technology

[0002] The dust sources in the coal charging and coke pushing of coking plants and the flue gas from the coke side furnace head are not fixed, and the dust generation point moves along the track with the coke quenching car or coke pushing car. In addition, the collected flue gas contains a lot of large spark-like particles and is at a high temperature. In order to protect the filter bags, the process technology route of water sealing tank + fire extinguishing cooler + dust removal ground station is often adopted for coking side and coke pushing dust removal.

[0003] In actual engineering implementation, there is often a problem of insufficient site space, which makes it impossible to install a fire-extinguishing cooler alone; or the cooling area of ​​the cooler is limited, so it is necessary to improve the temperature resistance standard of the filter bag. Both of these situations will significantly increase the project cost. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a water seal device with both spark capture and cooling functions. By modifying the original water seal trough, it saves equipment installation space, reduces project costs, and conserves project investment.

[0005] The technical solution of this utility model is: a water seal device with spark capture and cooling functions, including a water channel and a gas channel, the water channel and the gas channel being welded into a whole, the water channel resting on a slide rail, a movable support being provided at the lower part of the slide rail, and a support block being provided at the lower part of the movable support; the movable support and the support block are connected by bolts; a U-shaped bend is provided inside the water channel, and a cooling plate assembly and a positioning support sleeve are provided inside the gas channel; the U-shaped bend is inserted into the water channel and communicates with the gas channel, for guiding the flue gas collected by the U-shaped bend into the gas channel.

[0006] According to an embodiment of the present invention, a cooling plate assembly is arranged vertically and vertically inside the air duct groove along the airflow direction, and the cooling plate assembly is rigidly connected to the air duct groove through a positioning support sleeve.

[0007] According to an embodiment of the present invention, cooling plate groups are provided at intervals on the positioning support sleeve, and the positioning support sleeve and the cooling plate groups are connected by plug-in connection.

[0008] According to an embodiment of this utility model, a sewage hopper is welded below the water channel; a drain valve is connected below the sewage hopper; an air duct drain valve is connected below the air duct via a pipe; and the drain valve and the air duct drain valve are connected to the drain pipe via flanges.

[0009] According to an embodiment of this utility model, the U-shaped bend is fixedly connected to the dust collection pipe on the coke pusher or coke catcher through a flange.

[0010] According to an embodiment of the present invention, the air channel is a closed space enclosed by a steel plate and water, and the air channel and the water channel are rigidly connected.

[0011] According to an embodiment of the present invention, the cooling plate assembly is a multi-layer louvered structure.

[0012] According to an embodiment of the present invention, a maintenance manhole is provided at the bottom of the airway groove.

[0013] The cooling plate assembly adopts a staggered, wave-like layout, which forces the flue gas to form a serpentine flow path within the tank, effectively extending the gas residence time.

[0014] The flue gas collected by the U-shaped bend passes through the cooling plate assembly. Under the influence of inertial collision and gravitational settling, large particles and sparks in the flue gas directly settle in the gas channel, achieving the purpose of spark capture. The flue gas exhibits a serpentine flow trajectory, significantly increasing the contact area with the cooling plates and surrounding steel plates, thereby significantly improving heat exchange efficiency. During this process, large particles and sparks settle, reducing the mass of the flue gas and further increasing the heat exchange temperature difference, accelerating the cooling of the flue gas. In addition, the water-sealed trough is typically over 300 meters long, allowing for the installation of a sufficient number of cooling plate assemblies, forming a heat exchange area far exceeding that of conventional independent fire-extinguishing coolers, resulting in more significant cooling efficiency.

[0015] The added cooling plate assembly uses high-temperature and corrosion-resistant Mn material and a multi-layer louvered structure to enhance heat exchange efficiency. It also has the functions of spark interception and uniform heat dissipation, reducing the risk of bag filter bags burning in subsequent dust removal processes.

[0016] The air duct is equipped with a maintenance manhole at the bottom. Maintenance personnel only need to open the latch to enter the duct and clean up large particles and sparks that have settled, thus achieving regular dust removal and maintenance. This operation can maintain the air duct's flow space and ensure that the cooling plate assembly continues to perform its spark capture and pre-dust removal functions.

[0017] This utility model innovatively transforms the traditional structure of the water seal device tank by carefully arranging cooling plate groups inside the water seal tank. This cleverly replaces the fire-extinguishing cooler device that must be configured independently in the original process, achieving multiple benefits at once. It effectively reduces the temperature of the flue gas and deeply purifies the flue gas.

[0018] Moreover, this utility model abandons the original separate fire-extinguishing cooler equipment and only scientifically modifies the air passage of the water seal tank. While retaining the original function of the water seal device, it adds a cooling and purification function, thereby greatly saving the land area occupied by the project, significantly reducing the project cost, and saving a lot of capital investment for the project construction.

[0019] The advantages of this invention are its simplicity and practicality. Compared with traditional water seal devices, it significantly improves spark capture efficiency, requires no additional floor space, and is highly economical. Specifically, by adjusting the structure of the gas duct and adding cooling plate assemblies, large dust particles and sparks in the flue gas can be efficiently separated from the flue gas, successfully achieving the functions of flue gas cooling and pretreatment. At the same time, this water seal device can directly replace the independently installed fire-extinguishing cooler in the original process flow, further reducing the overall project footprint, lowering project costs, and bringing tangible economic benefits to the project construction.

[0027] The air passage 6 is equipped with a cooling plate assembly 7, which is connected to the air passage 6 via a positioning support sleeve 8.

[0028] Multiple cooling plate groups 7 are intermittently arranged along the direction of the coke oven, and supports are provided between the cooling plate groups 7 to ensure the strength of the cooling plate groups 7.

[0029] The positioning support sleeve 8 is equipped with a cooling plate group 7 and is connected by a plug-in connection; the flue gas collected by the U-shaped bend 5 passes through the cooling plate group 7, and under the action of inertial collision and gravity settling, large particles and spark-like substances in the flue gas are directly deposited in the gas channel trough 6, and the flue gas temperature is rapidly reduced, so as to achieve the purpose of spark capture and cooling of the flue gas.
