Description

Technical Field

[0001] The utility model relates to a steam-water separation device, in particular to a volute-type steam-water separation device built-in a steam boiler. Background Art

[0002] Steam boiler refers to boiler equipment that produces steam. It uses coal, oil, gas, natural gas, biomass and other fuels to produce steam or hot water through the heat generated by combustion, thereby meeting various production needs. Oil and gas industrial boilers often use a horizontal full wet back two-pass / three-pass structure, which has the advantages of compact structure, small size, fully assembled factory, small footprint, high degree of automation, etc., and is widely welcomed by people. A steam-water separation device is set on one side of the steam boiler, which can be used to separate the water vapor discharged from the steam boiler into liquid and gas.

[0003] In the prior art: CN202320294941.5 A boiler steam-water separation device, the utility model discloses a boiler steam-water separation device, including a cylinder, a head is arranged on both sides of the cylinder, and a high-pressure manhole device is arranged on the side of the head. The wet saturated steam generated by the water-cooled wall of the utility model enters the cylinder, and enters the cylinder tangentially through the introduction pipe through the steam-water mixture with a higher flow rate to generate a rotational motion. Under the action of centrifugal force, water droplets are thrown to the inner wall of the cylinder to make the steam and water initially separated. The separated water flows into the water volume of the steam drum through the guide vanes around the cylinder, and the saturated steam flows upward in the cylinder and flows in a zigzag manner in the gap of the corrugated plate of the top cap.

[0004] In the prior art, under the action of centrifugal force and inertial force, small water droplets are thrown onto the corrugated plate, and form a water film under the action of adhesion, and flow into the steam drum water volume through the cylinder wall, so that the steam and water are further separated. The discharge port set at the bottom of the cylinder facilitates the discharge of the separated water, thereby ensuring the practicability of the device. However, the middle part in the prior art cannot perform good liquid separation and diversion. Utility Model Content

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0018] The steam boiler has a built-in volute type steam-water separation device, which is provided with a separation device 1. The separation device 1 is provided with an air inlet 2 and an air outlet 3, and the air inlet 2 and the air outlet 3 are respectively located on both sides of the separation device 1.

[0019] When steam-water separation is required, the steam-water containing liquid is introduced into the separation device 1. A separation net 5 is provided in the separation device 1. The separation net 5 is used to condense the liquid, and then the condensed liquid drips into the bottom liquid collection component. The liquid collection component is used to store the liquid. Generally, the liquid collection component is a collection cavity 7. The collection cavity 7 is located at the bottom of the separation device, and a liquid outlet is provided on the separation device.

[0020] A transmission pipe 8 is provided on the liquid outlet. The transmission pipe 8 and the collecting chamber 7 are interconnected. A control valve is provided on the transmission pipe 8.

The discharge efficiency is further improved, and the liquid can be discharged in stages.

[0021] Water vapor containing liquid enters the separation device 1. Due to a certain temperature difference, the liquid will condense on the separation net 5. There are circular holes on the separation net 5 to utilize the dripping of the liquid. At the same time, the separation net 5 is divided into a top separation net and a bottom separation net. A separation gap is arranged between the top separation net and the bottom separation net. A guide component is arranged in the separation gap. The guide component can be used to guide the liquid, and the dripping liquid can be guided more centrally.
