[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1 As shown, the utility model provides a technical solution: an environmental protection device for collecting the mother liquid after the reaction of sulfur dioxide gas and soda water with centrifugation, comprising:
[0021] A shell 1 and a delivery pipe 5, a delivery pump 4 is arranged at the upper end of the side wall of the shell 1, the inlet end of the delivery pump 4 is connected to the mother liquor to be recovered through the delivery pipe 5, the outlet end of the delivery pump 4 is connected to the inside of the shell 1 through the delivery pipe 5, a draft fan 2 for conveying the residual sulfurous acid gas in the mother liquor to an external desulfurization tower is arranged on the top of the shell 1, a one-way valve 6 is arranged on the side wall of the delivery pipe 5 on the inlet end of the delivery pump 4, and a mother liquor alkali-making pipeline 8 for discharging the mother liquor and contacting it with soda ash for recovery is arranged on the side wall of the shell 1. This design uses the delivery pump 4 to deliver the mother liquor to be recovered to the inside of the shell 1 through the delivery pipe 5, and under the action of the one-way valve 6, the residual sulfurous acid gas in the mother liquor is prevented from flowing out in reverse, and at the same time, the draft fan 2 is operated to drain and discharge the residual sulfurous acid gas in the mother liquor entering the inside of the shell 1 to the inside of the desulfurization tower for treatment, thereby avoiding the sulfurous acid gas from flowing out to pollute the air and cause harm to the human body during alkali-making, thereby enhancing the environmental protection effect.
[0022] Reference Figure 1 and Figure 2 The other end of the mother liquid alkali-removing pipeline 8 is connected to a alkali-removing barrel for recovering the mother liquid and containing soda ash. This design facilitates the mother liquor to flow out of the mother liquid alkali-removing pipeline 8 and enter the alkali-removing barrel containing soda ash for mixing with the soda ash to be converted into a soda ash aqueous solution. An induced draft duct 3 connected to an external desulfurization tower is provided on the top of the induced draft fan 2. This design facilitates the connection of the fan to the external desulfurization tower by using the induced draft duct 3, so that the sulfurous acid gas enters the desulfurization tower for treatment.
[0023] Reference Figure 2 An air collecting plate 13 connected to the induced draft fan 2 is arranged on the upper side of the inner wall of the shell 1, and a plurality of air collecting holes 14 are arranged at the bottom of the air collecting plate 13. This design increases the drainage area for the sulfurous acid gas by using a plurality of air collecting holes 14, thereby facilitating the sulfurous acid gas to enter the interior of the air collecting plate 13 and be discharged from the induced draft fan 2, thereby accelerating the speed at which the sulfurous acid gas is discharged from the shell 1 and enters the interior of the external desulfurization tower.
[0024] Reference Figure 2 , Figure 3 and Figure 4A liquid dispersion pipe 10 is arranged inside the shell 1 and is placed below the gas collecting plate 13. Both ends of the liquid dispersion pipe 10 are closed ends. One end of the liquid dispersion pipe 10 is connected to the delivery pipe 5 on the outlet end of the delivery pump 4. A plurality of nozzles 11 are symmetrically arranged on the opposite side walls of the liquid dispersion pipe 10. A waterproof and breathable membrane 12 for shielding the plurality of gas collecting holes 14 is arranged at the bottom of the gas collecting plate 13. The design arranges a plurality of nozzles 11 on the opposite sides of the liquid dispersion pipe 10, so that the mother liquor is evenly dispersed when it enters the shell 1 from the delivery pipe 5, so that the residual sulfurous acid gas in the mother liquor is evenly dispersed and cooperates with the plurality of gas collecting holes 14, thereby further accelerating the discharge speed of the sulfurous acid gas.
[0025] Reference Figure 2 A stirring motor 7 is provided at the bottom of the shell 1, and a stirring rod 9 placed inside the shell 1 is provided on the output shaft of the stirring motor 7. The design drives the stirring rod 9 to rotate by using the stirring motor 7, so that the mother liquor is evenly dispersed, which is convenient for accelerating the subsequent melting treatment with the soda ash inside the alkali barrel containing soda ash and the speed of converting the alkali into a soda ash aqueous solution. A sealed bearing is provided at the connection between the output shaft of the stirring motor 7 and the shell 1, and a valve 81 is provided on the side wall of the mother liquor alkali pipeline 8, which improves the rationality of the design.
[0026] Reference Figure 1-Figure 4 As an embodiment of the utility model: when the mother liquor needs to be recovered, the staff uses the delivery pump 4 to deliver the mother liquor to be recovered to the inside of the shell 1 and into the inside of the liquid dispersion pipe 10, and the mother liquor is uniformly sprayed out from the multiple nozzles 11 arranged on the opposite side walls of the liquid dispersion pipe 10, thereby improving the uniformity of the residual sulfurous acid gas in the mother liquor to be dispersed into the inside of the shell 1, and at the same time, the induced draft fan 2 works under the action of the multiple gas collecting holes 14 of the gas collecting plate 13 to increase the area of the induced draft, so that the sulfurous acid gas remaining in the mother liquor sprayed uniformly from the multiple nozzles 11 can be quickly discharged from the multiple gas collecting holes 1 4 enters the interior of the gas collecting plate 13 to speed up the discharge of the sulfurous acid gas. Finally, the sulfurous acid gas, under the action of the induced draft fan 2, flows along the induced draft pipe 3 into the interior of the external desulfurization tower for treatment, thereby preventing the sulfurous acid gas from flowing out to pollute the air and cause harm to the human body during alkali treatment, thereby enhancing the environmental protection effect. Under the action of the one-way valve 6, the sulfurous acid gas remaining in the mother liquor is prevented from flowing out in reverse. Under the action of the waterproof and breathable membrane 12, the mother liquor sprayed from the nozzle 11 is prevented from entering the interior of the gas collecting plate 13, and does not affect the sulfurous acid gas from entering the interior of the gas collecting plate 13, thereby improving the practicality of the utility model.
