Description

Technical Field

[0001] The utility model relates to a steam exhaust device, in particular to a deep well casting steam exhaust control device, belonging to the technical field of steam exhaust. Background Art

[0002] During the deep well casting process, the ingots are cooled by secondary cooling water, and a large amount of steam will be generated in the casting well, which is not conducive to the operator observing the surface quality of the ingots in the casting well. In the prior art, the deep well casting steam discharge device is composed of a centrifugal fan, a pipe pre-buried between the centrifugal fan and the deep well steam guide pipe, and a steam collection hood connected to the deep well steam guide pipe. The water vapor is discharged to the outside of the factory through the pipes set on the deep well platform and the centrifugal fan installed on the pipeline. However, a large amount of steam is blown out of the room during the discharge process, resulting in a large amount of steam zone around, which leads to serious safety hazards around the factory.

[0003] How to control the potential safety hazards of steam emissions from deep well casting and ensure production safety and product quality is a technical problem that needs to be urgently solved by technicians in this field. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a deep well casting steam emission control device, which can effectively control the steam emission while ensuring the normal steam emission during the casting process, reduce the amount of discharged steam, and avoid the safety hazards caused by steam emission.

[0005] The technical solution adopted by the utility model to solve the technical problem is:

[0006] A deep well casting steam emission control device includes a steam emission unit and a steam emission control unit. The steam emission control unit includes an outdoor steam guide pipe, a steam condensation device, a steam condensate collection tank, a drainage pipeline and a support frame. One end of the outdoor steam guide pipe is connected to the steam emission unit and the other end is connected to the steam condensation device. The steam condensation device is connected to the steam condensate collection tank, and the bottom of the steam condensation device is supported by the support frame.

[0007] The steam discharge unit includes a centrifugal fan, a steam collecting hood, a deep well steam guide pipe and an indoor steam guide pipe. The centrifugal fan is connected to the steam collecting hood. One end of the steam collecting hood is connected to the deep well steam guide pipe and the other end is connected to the indoor steam guide pipe.

[0008] The drainage pipeline is connected with the rainwater pipeline through a valve.

[0009] The support frame is welded from waste angle steel materials and is welded to the bottom end of the steam condensing device.

[0010] In the deep well casting project, a large amount of steam is generated after the casting starts due to the contact between the high-temperature ingot and water. The generated steam enters the deep well casting steam emission control device through the deep well steam guide pipe, and enters the indoor steam guide pipe through the centrifugal fan. The generated steam is discharged from the indoor steam guide pipe to the outdoor steam guide pipe. The outdoor steam guide pipe is connected to a steam condensing device. Cooling water is contained in the steam condensing device. After the steam enters the steam condensing device, the amount of steam will be reduced after passing through the cooling water. The condensed water is collected through a steam condensate collecting tank, and is discharged into the rainwater pipe through a valve through a drainage pipeline. The residual steam is discharged through the opening above the condensate collecting tank. The utility model installs a steam condensing device at the steam discharge port, collects the steam in the steam condensing device through a steam guide pipe, and then discharges it after treatment.

[0011] The positive and beneficial effects of the utility model are as follows:

[0012] 1.

[0015] 4. The utility model is equipped with a centrifugal fan (37KW 50000m³ / h), which is connected to the steam collecting hood arranged above the deep well steam guide pipeline through a pipeline. The steam generated in the casting well is discharged to the outside through the negative pressure generated by the centrifugal fan in the pipeline. The impeller is made of stainless steel, and a drainage hole is arranged at the bottom of the fan to prevent the impeller from rusting due to long-term steam discharge and reduce safety hazards.
