According to the leaching tower, the blockage can be effectively avoided, and the labor intensity of workers can be greatly reduced; the reaction contact area between a gas phase and a liquid phase can be increased, and the reaction efficiency can be improved; and the phenomenon that the tail gas is discharged to the atmosphere when the polycrystalline silicon is produced can be avoided, and the guarantee of tail gas recovery can be provided for the environment-friendly production of polycrystalline silicon.
Description
Technical field
The utility model relates to production of polysilicon equipment and device technique field, is specifically related to a kind of processing acidifying washing smoke tower.
Background technology
In the production of polysilicon at home,, need corresponding absorption plant and accomplish owing to there is a large amount of waste gas in art production process, to discharge; Because it is acid that waste gas is mostly; Usually wash neutralization with alkaline solution or water, but because present domestic elution device unreasonable structure, can occur the phenomenon that a large amount of obstructions and drip washing fully neutralize aborning; There are a large amount of chlorosilanes and hydrogen chloride gas to overflow, periphery and equipment and environment have been caused very big influence.In addition, the fluid-tight of existing eluting column is on the upper strata, and uncontrollable height liquid seal causes the interior hydrolysate of tower in time to discharge, and causes frequently stifled tower, and equipment can't run well, and has greatly increased maintenance load.
The utility model content
The utility model technical problem to be solved provides a kind of processing acidifying washing smoke tower that can improve reaction efficiency, reduce labor strength, safety and environmental protection.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The utility model comprises interconnected two cylindrical shells and the pond that is fixed on two cylindrical shell lower ends; The top of said two cylindrical shells is fixed with shower respectively; Be fixed with gas approach on the cylinder lateral wall, another cylinder top is fixed with exhanst gas outlet, connects through tube connector between said two cylindrical shells; Upper end, said pond is fixed with the cylindrical shell deck, and said two cylindrical shells are fixed on the cylindrical shell deck and form a sealing integral body with the pond.
Said air inlet cylindrical shell is fixed with two showers that are crisscross arranged respectively with the top of the cylindrical shell of giving vent to anger, and said shower constitutes with the spiral nozzle that is connected with the insertion gas thread by inserting pipe.
Said tube connector " Y " shape for standing upside down, the top has the gas purging mouth.
Said two cylindrical shell bottoms are fixed with and are used for the bearing of cylindrical shell holding on the cylindrical shell deck.
The good effect of the utility model is following:
Be connected through tube connector between two cylindrical shells of the utility model; Increased the reaction time of gaseous phase materials, changed the reaction way of contact of gas-liquid phase materials, thereby improved reaction efficiency at Ta Nei and liquid phase material; The upper end has the gas purging mouth simultaneously; Can remove the hydrolysate in the tube connector, can effectively prevent to stop up, greatly reduce labor strength; The shower of the utility model adopts spiral nozzle, has increased the contact area of gas-liquid phase reaction, has improved reaction efficiency; The height of pond liquid level is exactly the height liquid seal of eluting column, can effectively the hydrolysate in the tower be taken out of outside the tower, has avoided in the production of polysilicon tail gas to the phenomenon of airborne release, produces for realizing the polysilicon environmental protection, and the guarantee of tail gas recycle is provided.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, the pond; 2, bearing; 3, tube connector; 4, gas approach; 5, cylindrical shell, 6, shower; 7, exhanst gas outlet; 8, cylindrical shell deck; 9, gas purging mouth.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1; The utility model comprises interconnected two cylindrical shells 5 and the pond 1 that is fixed on two cylindrical shell lower ends, and the top of said two cylindrical shells is fixed with respectively on 6, one cylinder lateral walls of two showers that are crisscross arranged and is fixed with gas approach 4; Another cylinder top is fixed with exhanst gas outlet 7; Connect through tube connector 3 between said two cylindrical shells, upper end, said pond is fixed with cylindrical shell deck 8, and said two cylindrical shells are fixed on the cylindrical shell deck whole with pond formation one sealing.
Use the utility model eluting column; The acidifying flue gas gets into from the gas approach of a cylindrical shell, when contacting reaction with the spray liquid that sprays in the shower, gets into another cylindrical shell by tube connector; Continue and the spray liquid reaction; The gas that has reacted is discharged by the exhanst gas outlet on top, the bottom-open of two cylindrical shells, and leacheate is spilled over to the pond from the bottom.
The utility model tube connector has adopted " Y " type threeway that has certain inclination angle that is handstand; Its two ends are connected with two cylindrical shells respectively through flange; Increased the reaction time of gaseous phase materials at Ta Nei and liquid phase material; Thereby improved the reaction efficiency of tower, reaction efficiency improves more than 20% on existing basis.The upper end has the gas purging mouth, utilizes high pressure nitrogen to purge and prevents communicating pipe to stop up, and has significantly reduced the number of times that stops up, and has greatly reduced labor strength.
The utility model shower inserts pipe by a stainless steel and constitutes through the stainless steel spiral nozzle that is threaded, and spiral nozzle is a kind of nozzle that produces taper or umbrella water curtain, mainly is configured to a screw cone.Current receive the guide effect of the spiral conical surface when spraying at a high speed, produce rotation and since centrifugal force to around the formation water curtain that scatters.Can produce umbrella, taper jeting effect by different cone curved surfaces, therefore increase the contact area of gas-liquid phase reaction, improve reaction efficiency.
The utility model bearing twines the middle and lower part that the method manufacture craft is fixed on cylinder body outer wall through machinery; Be fixed with the cylindrical shell deck on the pond; Two cylindrical shells and pond through the bearing holding on cartridge mount; It is whole to form a sealing, and the height of pond liquid level is exactly the height liquid seal of eluting column, can effectively the hydrolysate in the tower be taken out of outside the tower.
The above; Preferable case study on implementation for the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
