Problems solved by technology

Due to the change of steam consumption in the steam system, the steam pressure fluctuates frequently. When the steam user load suddenly increases and the pressure in the heat accumulator suddenly drops, a large amount of saturated water in the heat accumulator will flash, and a large amount of steam will be directly discharged from the outlet. When the steam velocity is high, this makes the steam carry a lot of water, which affects the steam quality at the outlet of the heat accumulator

Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] The structure of the vapor-water separation device of the variable pressure steam accumulator of the present invention is as follows: figure 1 figure 2 As shown, it includes a heat accumulator body 1 , a pipe with non-uniform holes 2 , a steam outlet main pipe 3 , a spiral dehydrator 4 , a steam inlet main pipe 5 and a circulation cylinder 6 . On the upper part of the heat accumulator body 1, a non-uniform flute pipe 2 is arranged parallel to the axis of the heat accumulator. The flange is connected with the spiral dehydrator 4. The steam inlet main pipe 5 is connected with the circulation drum 6 through the distribution pipe.

[0019] The structure of screw dehydrator 4 of the present invention is as image 3 Figure 4 As shown, in the spiral dehydrator 4, the steam inlet pipe 7 is tangentially connected to the dehydrator cylinde...

Abstract

A separation device of steam and water for heat accumulator in change pressure type sets flute pipe with non-uniform hole at upper part of the heat accumulator and to set in parallel with shaft centre of it connects screw dewaterer at outlet flange of steam output main pipe as steam input pipe of the screw dewaterer to be connected with dewaterer cylindrical body in tangential direction, steam output pipe to be inserted into cylindrical body for fixing, steam input pipe baffle to be set in the steam input pipe in tilt to block a half area of flowing for steam stream. The device can decrease a lot of water contained in the steam o f heat accumualtor in change pressure to raise effectively the quality of steam.

Description

Technical field: [0001] The invention relates to a steam-water separation device for a pressure-variable steam heat accumulator, which is applied to a steam system with a pressure-variable heat accumulator, and relates to the fields of chemical industry, energy, light industry and the like. Background technique: [0002] Variable pressure steam heat accumulator is installed in the place where the steam pressure fluctuates greatly, and it uses the nature of steam and saturated water to store heat when the steam pressure changes, so that the load of the boiler basically does not change when the steam user load changes. change, to achieve the purpose of stabilizing the steam source pressure by cutting peaks and filling valleys. When the user's demand is small, the excess steam generated by the boiler is stored in the heat accumulator; when the user's demand is large, the heat accumulator will release the stored steam. In order to make the most of the space in the accumulator, ...
