Problems solved by technology

[0002] The steam drum is an indispensable part of the waste heat of the cement kiln head for power generation, and the steam-water separation device inside the water bubble is a very important structure of the steam drum. The quality of its design directly affects the purity of the separation of gas and water. At present, The steam drum is not designed with a steam-water separation device, so that the gas in the steam drum entering the superheater contains moisture, causing the superheater to burst and affecting the life of the entire boiler operation

Embodiment Construction

[0014] see figure 1 It can be seen that the water vapor separation device is installed in the steam drum of the waste heat boiler at the kiln head of the cement kiln to dehumidify the gas output from the steam drum. The pipe 2 is arranged on the top of the steam drum body 1 to output steam upwards, the steam outlet pipe 5, and the water supply pipe 10 extending into the steam drum, the continuous sewage pipe 9, the dosing pipe 11 and the water surface sewage pipe 12.

[0015] The water-steam separation device of the present invention mainly adopts the mode of two separations, wherein the first separation is arranged at the mouth of the inner rising pipe 2 of the steam-water mixture input on the steam drum body, and the secondary separation device is arranged at the steam drum body 1 to output the steam of the gas. At the mouth of the outlet pipe 3, such a combination can achieve a better separation effect.

[0016] The primary separation device includes an arc-shaped buffer c...

Abstract

The invention discloses a steam and water separation device for a steam dome, and the device provided by the invention comprises a primary separation device and a secondary separation device, wherein the primary separation device is arranged on the mouth of an ascending tube used for inputting a steam and water mixture in a steam dome body; and the secondary separation device is arranged on the mouth of a steam extraction tube for outputting gas in the steam dome body. The device has a simple structure and is convenient to manufacture, install and overhaul; meanwhile, good water circulation working condition can be guaranteed, and overlarge circulation resistance can be avoided; and in addition, the device can effectively carry out steam and water separation so as to lower the tube explosion possibility of the superheater, and satisfies the operation reliability of the boiler and user requirements.

Description

technical field [0001] The invention relates to the technical field of recovering waste heat from a cement kiln for power generation, and more specifically relates to a steam-water separation device for a steam drum of a waste heat boiler at the kiln head of a cement kiln. Background technique [0002] The steam drum is an indispensable part of the waste heat of the cement kiln head to generate electricity, and the steam-water separation device inside the water bubble is a very important structure of the steam drum. The quality of its design directly affects the purity of the separation of gas and water. Currently, The steam drum is not designed with a steam-water separation device, so that the gas in the steam drum entering the superheater contains moisture, causing the superheater to burst and affecting the life of the entire boiler operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a steam-water separa...
