Problems solved by technology

However, part of the water after heat exchange evaporates, and cold water needs to be supplied from an external water source to the steam drum. The supplied cold water cannot be quickly and evenly mixed with the higher temperature water in the steam drum, especially the water discharged from the...

Abstract

The invention discloses a steam bag, which comprises a shell, a yielding water temperature reduction pipe and a steam-water separation device, wherein a water supply pipe, a water outlet pipe, a backflow pipe and a steam outlet pipe are arranged on the shell; a water inlet end of the water outlet temperature reduction pipe is communicated with the water supply pipe, and the water outlet end of the water outlet temperature reduction pipe is communicated with the water outlet pipe; and the steam-water separation device is arranged in the shell and is used for separating water and steam flowing back to the shell from the backflow pipe. The steam bag of the invention can reduce the temperature of the yielding water, prevent circulating cooling water from vaporization at a circulating pump, decrease the pressure fluctuation in a circulating system and reduce the damage and the harmful influence to the circulating pump. In addition, the steam bag can effectively separate the steam and the water, thereby preventing steam from flowing into the circulating water in the lower part of the steam bag and preventing the water in a boiler from being carried out of the steam bag when the steam is discharged.

Description

technical field [0001] The invention relates to a steam drum, in particular to a steam drum used in a waste heat boiler. Background technique [0002] In the field of metallurgical industry, the waste heat boiler is used to recover the heat of the high-temperature flue gas discharged from the metallurgical furnace. The high-temperature flue gas discharged from the metallurgical furnace enters the waste heat boiler body, and the heat is recovered after heat exchange in the waste heat boiler body. The steam drum is a part of the waste heat boiler circulation system, which is used to supply cooling water to the waste heat boiler body, receive the return steam-water mixture and discharge the steam, and the water in the steam drum is recycled. [0003] In waste heat boilers using a forced circulation system, a circulation pump is usually used to supply the water in the steam drum to the waste heat boiler body. However, part of the water after heat exchange evaporates, and cold w...
