Detailed description of the invention

Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.

A kind of scrubbing tower of the preventing urea from caking of this utility model offer that Fig. 1 is shown, including tank body 1 with lay respectively at tank body 1 top, the air vent 15 of afterbody, sewage draining exit 14, air vent 15 is convenient discharges clean gas outside tank body 1 after gas scrubbing, and sewage draining exit 14 precipitate in liquid after cleaning is discharged outside tank body 1.nullWashing, purifying device 2 it is disposed with from top to bottom in described tank body 1、Valve plate 3、Eddy flow flaggy 4、Deflection plate 5、Water mist separator 17、Shower 6、Screen plate 6,And on shower 6, it is provided with spray head 6a,The dust remained in gas is carried out by the current that the gas after being filtered by screen plate 6 is sprayed by spray head 6a,And the water smoke after cleaning leads to water mist separator 17 and separates gas and water smoke,Gas after separation by deflection plate 5 make gas rise while repeatedly bending move up,The clean result making gas is more preferable,Cross eddy flow flaggy 4 and rotate rising,While rotating rising, remaining water smoke can be discharged by eddy flow flaggy 4,Finally it is fully finished the gas after washing then further to be removed by valve plate 3,Finally ensure that gas carries out absorbing by washing, purifying device 2 to decompose,The final gas discharged outside tank body 1 is clean gas,Complete the washing of carbamide.

Described valve plate 3, deflection plate 5 are multiple structure, every layer of interlaced setting of deflection plate 5, the bending repeatedly of the gas after being separated by water mist separator is made to move up, increase the contact area of gas, and every layer of the most downward-sloping setting of deflection plate 5, the angle of inclination of deflection plate 5 is 10 ° ~ 30 °, preferably 15 °, can be prevented effectively from because the water smoke of residual is accumulated on deflection plate 5, and cause being formed on deflection plate 5 urea from caking;Every layer of interlaced setting of valve plate 3, and the free end of valve plate 3 is provided with baffle plate, the passage allowed gas between valve plate 3 turns round, and improves the effect of gas scrubbing;It is provided with web plate 7 below described screen plate 6, and web plate 7 is arranged with on filter cylinder 8, and filter cylinder 8 winding and is provided with spiral deflector 10;And web plate 7, filter cylinder 8, spiral deflector 10 surface are all coated with PTFE film, the low friction of PTFE thin film and antistick characteristic, the frictional resistance between dust and web plate 7, filter cylinder 8, spiral deflector 10 in gas can be reduced, be greatly improved purification efficiency.It is collecting tank 11 below described filter cylinder 8, collecting tank 11 sidewall is provided with the reflux line 12 being connected with shower 6, and on reflux line 12, is provided with reflux pump 13;It is provided with air inlet 9 on described tank body 1 sidewall, and air inlet 9 is positioned at above collecting tank 11.The gas in tank body 1 is entered into by air inlet 9, first spin along the periphery of filter cylinder 8 upper body according to the water conservancy diversion of spiral deflector 10, while motion of spinning, the dust in gas is first filtered, and remain in the current that on spiral deflector 10 and filter cylinder 8, dust is sprayed by spray head 6a after filtering and dust flushing is fallen in collecting tank 11, the gas entered in filter cylinder 8 enters into above web plate 7 again by web plate 7, the sewage in collecting tank 11 precipitation by self simultaneously, the clear water on collecting tank 11 upper strata is transported to shower 6 by the reflux pump 13 on reflux line 12 and reuses, in collecting tank 11, the precipitate of precipitation is then discharged outside tank body 1 by sewage draining exit 14.

The outer rim of described spiral deflector 10 and the inwall seamless welding of tank body 1, it is ensured that enter into the gas in tank body 1 and all spin motion, the filter effect of raising gas;Being additionally provided with observation window 16 on described tank body 1, observation window 16 is convenient to be observed the washing situation of gas in tank body 1;Described spiral deflector 10, filter cylinder 8, web plate 7 are PE material, because the corrosivity of carbamide is bigger, it is to avoid after filtering for a long time, spiral deflector 10, filter cylinder 8 and web plate 7 are caused corrosion;It is provided with level sensor, it is to avoid water level in collecting tank 11 is too high causes the liquid in collecting tank 11 to enter in air inlet 9, and filter cylinder 8 is cylindrical, and specially filter cylinder 8 is consistent with the shape of tank body 1 in collecting tank 11.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
