The utility model relates to a steam recycling device in the steel-making industry.
Background
At present, as shown in fig. 1, a steelmaking plant needs to use vaporized steam, and the vaporized steam also contains certain energy after the use, so that the steelmaking plant generally generates electricity. Referring to fig. 1, a plurality of boil-off steam recovery circuits 10 are grouped together in a collection line 11, and the collection line 11 is connected to a downstream power plant 13 (e.g., a steam turbine) via a transfer line 12.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem who solves: in practice, the pressure recovered from each vaporized vapor recovery pipeline is normally 0.8MPa, but the pressure of the gas delivered to the downstream of the collecting pipeline is high or low due to different operation conditions of each vaporized vapor recovery pipeline or other reasons, and the power generation equipment can hardly generate power when the pressure of the delivered gas is lower than 0.4MPa, but the gas is still delivered, which causes energy waste.
The technical scheme of the utility model specifically does:
the utility model provides an air supply device for vaporization steam power generation, includes the manifold pipeline, and its exit end that communicates a plurality of vaporization steam recovery pipelines, manifold pipeline intercommunication conveying pipeline's entrance point, conveying pipeline can communicate the power generation facility of low reaches, and conveying pipeline is equipped with the air-vent valve.

Detailed Description
Referring to fig. 2, the air supply device for vaporization steam power generation includes a collecting duct 11 communicating with outlet ends of a plurality of vaporization steam recovery ducts 10, the collecting duct 11 communicating with an inlet end of a delivery duct 12, and the delivery duct 12 communicating with a downstream power generation facility 13.
The delivery line 12 is provided with a pressure regulating valve 20.
The pressure regulating valve 20 is disposed at the inlet end of the conveying pipeline 12, and is a self-operated pressure regulating valve, and the minimum value of the pressure regulating valve is generally 0.6 MPa.
As shown in fig. 3, for convenience of adjustment, a valve body 32 is fixed in an inner cavity of the pressure regulating valve 20, the inner cavity is divided into a water inlet cavity 31 and a water outlet cavity 30 by the valve body 32, a tapered through hole 33 with a small upstream and a large downstream is formed in the valve body 32, a tapered valve core 34 with a small upstream and a large downstream is arranged in the through hole 33, the valve core 34 is fixed at one end of a valve rod 35, a sealing chamber 40 is fixed on the outer side of a shell of the pressure regulating valve 20, a piston 41 is arranged in the sealing chamber 40, the other end of the valve rod 35 extends into the sealing chamber 40 and is fixed on the side surface of the piston 41, a compression spring 42 is arranged between the other.
In the case where some of the devices upstream of the boil-off vapor recovery line temporarily do not discharge vapor, the vapor in the collecting line 11 may flow in the reverse direction to cause damage, and for this reason, a check valve 21 is fixed to the outlet end of each boil-off vapor recovery line 10.
The working principle is as follows:
when the pressure in the collecting pipe 11 is high, as shown in fig. 4, the pressure in the inlet chamber 31 is high, the valve core 34, the valve rod 35 and the piston 41 move to the side of the compression spring 42 as a whole, the through hole 33 is opened, the inlet chamber 31 is communicated with the outlet chamber 30, and power generation can be realized.
As shown in fig. 3, when the air pressure in the collecting pipeline 11 is small, the pressure in the water inlet chamber 31 is small, the pressure spring 42 causes the valve core 34, the valve rod 35 and the piston 41 to move to one side of the through hole 33 as a whole, the through hole 33 is blocked, the water inlet chamber 31 and the water outlet chamber 30 are not communicated, the air in the collecting pipeline 11 does not leak, and when the air pressure in the collecting pipeline 11 is large enough, the power generation is continued.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
