Abstract
The problem of the utility model discloses a kind of rotational flow plate defrosters for handling phosphoric acid fluorinated tail gas, solve existing demister for handling existing easy blocking during fluorinated tail gas, and defogging effect is bad.Technical solution includes the shell ring being horizontally set at the top of tower body and the polylith eddy flow plate being diametrically mounted on shell ring, one end of the eddy flow plate is connect with shell ring, the other end is connect with tower body wall surface, and the vertical width of the eddy flow plate is gradually increased by the lateral tower body side surface side of shell ring.The utility model structure is extremely simple, is not easy to block up, and defogging effect is good.
Description
Technical field
The utility model is related to field of chemical equipment, specifically a kind of rotational flow plate defroster.
Background technology
The current phosphoric acid by wet process industrial tail gas absorption system in China generally uses venturi+cyclonic spray scrubber by wet method phosphorus
The fluorinated tail gas that sour device generates discharges after being absorbed with water, and fluoride washing system easily generates drop entrainment and mist, so as to
Destroy effectively operating and outlet content of fluoride is significantly increased for washing system, therefore the follow-up liquid also needed by entrainment in the gas phase
Drop and mist are detached could qualified discharge.
Phosphoric acid by wet process industrial production producer of the country generally sets demister in washer tower top at present, but due to process object
For phosphoric acid fluorinated tail gas, hydrolysis can occur in absorption process and generate silica gel deposit, easily extremely demister is caused to block up for fluorine tail gas
Plug, defogging effect is bad, influences normal use.
Invention content
The purpose of this utility model is in order to solve the above-mentioned technical problem, to provide that a kind of structure is extremely simple, is not easy to block up, and is removed
The rotational flow plate defroster of the good processing phosphoric acid fluorinated tail gas of fog effect.
Technical solution is by the shell ring being horizontally set at the top of tower body and the polylith eddy flow plate being diametrically mounted on shell ring
Composition, one end of the eddy flow plate are connect with shell ring, and the other end is connect with tower body wall surface, and the vertical width of the eddy flow plate
Degree is gradually increased by the lateral tower body side surface side of shell ring.
The shell ring diameter accounts for the 50~70% of inner diameter of tower.
The top and bottom of the shell ring are equipped with conical end socket.
The vertex of a cone of the cone end socket highly accounts for the 15~35% of shell ring diameter.
The problem of for background technology, inventor existing rotational flow plate defroster has been carried out maximum simplification and
Transformation, the rotational flow plate defroster are only made of shell ring, end socket and eddy flow plate, eliminate extra component, reduce blocking
Possibility.The vertical width of design eddy flow plate is gradually increased by the lateral tower body side surface side of shell ring, main to consider eddy flow plate
Between can suitably be overlapped, improve mist separative efficiency；It is cone by head design, fluorinated tail gas can be reduced in this way to shell ring
Impact, while effectively disperse fluorinated tail gas.The shell ring diameter accounts for the 50~70% of inner diameter of tower, and crossing conference makes spiral board effective
Area significantly reduces, and the too small drop that can be unfavorable for is got rid of to tower wall, is unfavorable for the support of cyclone and the distribution of fluorinated tail gas is made
With；The vertex of a cone of the cone end socket highly accounts for the 15~35% of shell ring diameter, to reach effective dispersion fluoro-gas, avoid containing
The purpose of fluorine gas impact crosses conference and increases support load and waste, too small to reduce application effect.
The utility model is simple in structure, is not easy to plug, and defogging effect is good, especially suitable for handling phosphoric acid fluorinated tail gas, tool
There is vast market prospect.

Body.
Specific embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings：
The utility model is by being horizontally set on the shell ring 102 of 3 top top layer nozzle of tower body, 2 top, being diametrically mounted to
Polylith eddy flow plate 101 on shell ring 102 and 103 composition of cone envelope mounted on the top and bottom of shell ring 102, the rotation
One end of flowing plate piece 101 is connect with shell ring 102, and the other end is connect with 3 wall surface of tower body, and the vertical width of the eddy flow plate 101
Degree h1 is gradually increased by 102 lateral 3 side surface side of tower body of shell ring.The 102 diameter h2 of shell ring accounts for the 50~70% of 3 internal diameter of tower body.
The vertex of a cone height h3 of the cone end socket 103 accounts for the 15~35% of 102 diameter h2 of shell ring.The utility model is used for wet method phosphorus
After sour industrial tail gas absorption system, compared with traditional demister, drop fog effect is apparent, and fluorinated tail gas qualified discharge persistently makes
After 3 years, no blockage problem occurs.
