Embodiment Construction

[0011] Such as figure 1 and figure 2 As shown, the device for effectively reducing the circulating water of the support beam in the heating furnace includes a cooling water pipe 1 in the support beam, at least three spiral spoilers 2 and several connecting rods 3, and the spiral spoiler 2 passes through the The plurality of connecting rods 3 are sequentially connected and arranged in the cooling water pipe 1 of the support beam, and the first spiral spoiler along the water flow direction of the cooling water pipe 1 in the support beam is fixedly connected with the inner wall of the cooling water pipe 1 . The spiral spoiler 2 can be formed by helically bending a steel plate.

[0012] In order to achieve a better water flow spiral effect, the spiral angle of the spiral spoiler 2 is 45-180 degrees, and the length of the spiral spoiler 2 is 100mm-400mm. The distance between each spiral spoiler 2 is 300-3000mm.

[0013] To facilitate the manufacture of the device, the spiral sp...

Abstract

The invention discloses a device capable of reducing water recirculation rate of a supporting beam in a heating furnace effectively, namely at least three spiral-type spoilers are connected to and arranged in a supporting beam cooling water pipe through a plurality of connecting rods sequentially, and the first spiral-type spoiler is fixedly connected with the inner wall of a cooling water pipe along the water flow direction of the cooling water pipe of the supporting beam. By using the device, the adhesion of circulated water vapor bubbles on the inner wall surface of the supporting beam is avoided, the cooling effect of the supporting beam is ensured, the safety production hazard is eradicated, and the running energy consumption of the cooling circulation system is reduced.

Description

technical field [0001] The invention relates to a device for effectively reducing the circulating water volume of a support beam in a heating furnace. Background technique [0002] Generally, the heating furnace is equipped with blank supporting beams to support and place the blanks. Since the supporting beams work in the high-temperature environment in the furnace, in order to ensure their structural strength, the supporting beams in the furnace need to be cooled. The way in which water is vaporized to cool the support beam is called vapor cooling. The support beam adopting vaporization cooling will produce a large number of bubbles on the inner wall of the support beam due to the violent vaporization of saturated water in the beam. If the air bubbles cannot be quickly taken away by the water flow, an air film will be formed on the inner wall of the support beam, which will greatly reduce the heat exchange efficiency between the inner wall of the support beam and the cooli...
