Technical Field

[0001] The present invention relates to the technical field of pollution treatment, and particularly to a furnace pollution treatment device. Background Art

[0002] During the process of pouring molten iron from the furnace, the molten iron is prone to generating a large amount of smoke when contacting with air. The smoke contains dust and water vapor, resulting in environmental pollution. At the same time, due to the volatilization of part of the gaseous molten iron, the loss is serious. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a furnace pollution treatment device, which can extract air at the top of the furnace mouth, absorb dust and water vapor, reduce gas pollution, and can adjust the coverage of the umbrella cover according to the situation of the steam.

[0004] The furnace pollution treatment device according to an embodiment of the present invention includes:

[0005] A gantry, which is erected on the furnace;

[0006] A suction device, which is installed on the gantry. The suction device includes an umbrella cover and a negative pressure device. The umbrella cover is installed on the gantry through a lifting bracket, the negative pressure device is installed on the gantry, and an air outlet hole is opened at the top of the umbrella cover. The air outlet hole is connected to the negative pressure device through a suction pipe;

[0007] The umbrella cover includes a main layer umbrella cover and at least one sub-layer umbrella cover. The sub-layer umbrella cover is movably installed on the main layer umbrella cover. The main layer umbrella cover includes a main layer umbrella frame and a main layer umbrella surface. The main layer umbrella surface covers the main layer umbrella frame. The sub-layer umbrella cover includes a sub-layer umbrella frame and a sub-layer umbrella surface. The sub-layer umbrella surface covers the sub-layer umbrella frame. A telescopic device is installed on the main layer umbrella frame. One end of the sub-layer umbrella frame is connected to the telescopic device. The telescopic device is used to drive the sub-layer umbrella frame to extend or retract.

[0008] The furnace pollution treatment device according to an embodiment of the present invention has at least the following beneficial effects: A suction device is arranged at the top opening of the furnace to suck the smoke generated during the processing of the furnace, so as to prevent the dust and water vapor from being randomly dispersed into the environment and causing environmental pollution. Among them, the umbrella cover of the suction device is covered above the opening at the top of the furnace through a lifting bracket. When the furnace is processing or pouring molten iron, the suction device is started at the same time. The smoke generated by the furnace is sucked above the furnace due to the suction of the negative pressure device and flows to the air outlet hole of the umbrella cover under the aggregation and guidance of the umbrella cover, and then flows to the next treatment mechanism through the suction pipe.

[0009] Moreover, the umbrella cover is provided with two layers, including a main umbrella cover and a secondary umbrella cover. The secondary umbrella cover can be extended or retracted under the drive of a telescopic device to change the covering range of the overall umbrella cover over the opening of the furnace. On the one hand, the applicability of the umbrella cover can be improved. On the other hand, the effect of gathering and guiding the smoke by the umbrella cover can be ensured. The overall structure is compact, which helps to improve the production environmental protection benefits of the enterprise and improve the production environment of workers.

[0010] In the furnace pollution treatment device according to an embodiment of the present invention, at least one support rod is provided between the main umbrella frame and the secondary umbrella frame. One end of the support rod is movably connected to the main umbrella frame, and the other end is fixedly connected to the secondary umbrella frame. Wherein, the support rod is used to strengthen the connection stability between the main umbrella frame and the secondary umbrella frame.

[0011] In the furnace pollution treatment device according to an embodiment of the present invention, the lifting bracket includes an annular bracket, a first connecting rod, and a second connecting rod. The annular bracket is connected to the gantry through the first connecting rod, and the umbrella cover is connected to the annular bracket through the second connecting rod.

[0012] In the furnace pollution treatment device according to an embodiment of the present invention, the umbrella cover is an openable structure. The annular bracket is provided with a first drive, a circular guide rail, and rollers. The rollers are installed in cooperation with the circular guide rail. The first drive is connected to the rollers. One end of the second connecting rod is connected to the rollers, and the other end of the second connecting rod is connected to the movable edge of the umbrella cover. It should be noted that the umbrella cover can be folded. When the furnace is processing or pouring molten iron, the first drive is started simultaneously to drive the rollers to rotate. The rollers move along the circular guide rail to drive the umbrella cover to open. And workers can control the opening degree of the umbrella cover by controlling the stroke of the rollers. When workers need to store and fold the umbrella cover, the first drive can be reversed. The structure is compact and reliable, avoiding manual operation of workers to open or fold the umbrella cover, which helps to ensure the production safety of workers, and can also reduce the labor intensity of workers and improve production efficiency.

[0013] In the furnace pollution treatment device according to an embodiment of the present invention, a steam pressure sensor is provided on the side of the umbrella cover facing the furnace. The steam pressure sensor is used to monitor the steam impulse generated during the reaction of the furnace to facilitate adjusting the opening degree of the umbrella cover.

[0014] In the furnace pollution treatment device according to an embodiment of the present invention, a gas sensor is provided on the side of the umbrella cover facing the furnace. The gas sensor is used to detect the components and concentration in the suctioned gas to judge the reaction situation in the current furnace.

[0015] In the furnace pollution treatment device according to an embodiment of the present invention, a cooling device is further included. The cooling device is connected to the suction device. The cooling device is used to cool the suctioned gas, cool and solidify the dust, and recover the iron materials, which helps to reduce the loss of the enterprise and reduce the production cost.

[0016] According to the furnace pollution treatment device of the embodiment of the present invention, both the main layer umbrella surface and the secondary layer umbrella surface are made of heat-resistant materials. Since the smoke generated during the furnace reaction contains high-temperature water vapor, using heat-resistant materials for the main layer umbrella surface and the secondary layer umbrella surface can extend the service life of the umbrella cover.

[0017] According to the furnace pollution treatment device of the embodiment of the present invention, both the main layer umbrella surface and the secondary layer umbrella surface are made of aluminum foil. The umbrella surface made of aluminum foil has the advantages of heat insulation, moisture resistance, and easy cleaning.

[0018] According to the furnace pollution treatment device of the embodiment of the present invention, an X-axis moving mechanism and a Y-axis moving mechanism are provided on the gantry. The X-axis moving mechanism is connected to the gantry, the Y-axis moving mechanism is connected to the X-axis moving mechanism, and the suction device is connected to the Y-axis moving mechanism.
