Description

Technical Field

[0001] The present application relates to the field of waste alkali liquor treatment equipment, and in particular to a desulfurization waste alkali liquor treatment tower. Background Art

[0002] In the desulfurization system, the lower section of the desulfurization tower is designed to adopt a vacuum potassium carbonate desulfurization process, and 5% NaOH alkaline solution is added to the upper section for circulation washing. A part of the circulating alkaline solution is continuously sent to the ammonia distillation device to decompose fixed ammonium.

[0003] The concentration of NaOH solution increased to 17.3%, resulting in a large amount of waste alkali liquor that could not be disposed of. In addition, the salt content of the waste alkali liquor after the upper desulfurization stage was as high as 20%. After the waste alkali liquor was mixed with the remaining ammonia water, the sulfide content of the waste alkali liquor used to decompose the fixed ammonium salts during ammonia evaporation was an average of 7.8g / l, and the cyanide content was about 20mg / l. This resulted in high TDS, sulfide, and cyanide content in the ammonia evaporation wastewater, affecting the biochemical system and salt balance of the water treatment plant. Therefore, the desulfurization waste alkali liquor needed to be treated to ensure the normal discharge of the wastewater. For example, a waste alkali liquid treatment device disclosed in China Publication No. CN207827943U neutralizes the strong alkalinity of the waste alkali liquid through an acid-base neutralization treatment method, stirs it through a stirring mechanism, mixes it fully, and has a good neutralization effect, and then adsorbs the harmful gases generated by the neutralization. The treatment effect is good, but the continuity of the waste alkali liquid treatment is poor. When treating the waste alkali liquid, the device cannot neutralize and filter the alkaline waste liquid in advance, thereby reducing the treatment effect of the alkaline waste liquid inside the treatment tower.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figures 1-6 The present application provides a desulfurization waste alkali liquid treatment tower, including a waste liquid treatment component 10 and a pre-filtration mixing component 20.

[0028] Among them, the waste liquid treatment component 10 can treat the waste alkali liquid generated by desulfurization, and the pre-filtration mixing component 20 can mix the waste alkali liquid with the neutralization liquid before it enters the treatment tower 110 and filter it through the filter element 290 for pre-treatment before entering the treatment tower 110 for further reaction.

[0029] See also Figure 1 and Figure 4 The waste liquid treatment assembly 10 includes a treatment tower 110, with a top cover 120 disposed on top of the treatment tower 110. Specifically, a liquid outlet is disposed at the bottom of the treatment tower 110, and support legs 160 are mounted on the bottom sidewalls of the treatment tower 110. A liquid outlet hose 270 extends through the top cover 120 into the interior of the treatment tower 110. The waste alkali liquid enters the interior of the treatment tower 110 through the liquid outlet hose 270.

[0030] In this embodiment, downwardly inclined guide plates 140 are equidistantly provided on both sides of the interior of the treatment tower 110. A filter plate 150 is installed at the bottom of the treatment tower 110. Among them, when the waste liquid enters the interior of the treatment tower 110 through the liquid outlet hose 270, it will first pass through the first guide plate 140, then fall into the second guide plate 140, and then fall into the third guide plate 140. After the action of multiple guide plates 140, it will fall onto the filter plate 150 and be discharged through the discharge pipe 130 after filtration. Through the cooperation of multiple guide plates 140, the time for the waste liquid to fall to the bottom of the treatment tower 110 can be extended, thereby increasing the mixing time between the waste alkali liquid and the neutralizing liquid, and when falling on the guide plate 140, the waste alkali liquid and the neutralizing liquid will have a certain collision, thereby improving the mixing effect, thereby making the treatment effect of the waste alkali liquid better.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The pre-filtration mixing assembly 20 includes a mounting plate 210, which is disposed on the top of the waste liquid treatment assembly 10. Specifically, a support column is installed at the bottom of the mounting plate 210, and the bottom end of the support column is connected to the top cover 120. A mixing chamber 220 is mounted on the mounting plate 210, and a filter element 290 is disposed inside the mixing chamber 220. The mixing chamber 220 is provided with an openable chamber cover 230, and the chamber cover 230 is connected to a waste liquid inlet pipe 250. The side of the waste liquid inlet pipe 250 is connected to a neutralizing liquid inlet pipe. A vibration motor 260 is installed on the outer wall of the mixing chamber 220. A liquid outlet hose 270 is connected to the bottom of the mixing chamber 220, and the bottom end of the liquid outlet hose 270 extends to the interior of the waste liquid treatment assembly 10. Among them, the waste alkali liquid and neutralizing liquid generated by desulfurization enter the mixing chamber 220 through the waste liquid inlet pipe 250 and the neutralizing liquid inlet pipe at the same time for mixing. The mixed waste liquid is filtered by the filter element 290 and then flows out through the liquid outlet hose 270 into the treatment tower 110. At the same time, the vibration motor 260 vibrates, so that the mixed liquid has a better mixing effect. When the filter element 290 needs to be replaced, the chamber cover 230 can be opened to clean and replace it. Through the arrangement of the mixing chamber 220 and the filter element 290, the waste alkali liquid and the neutralizing liquid can be filtered and mixed in advance, thereby improving the treatment effect of the waste alkali liquid and saving the time of the waste alkali liquid treatment. The chamber cover 230 can be opened and arranged on the mixing chamber 220, making it convenient to replace and clean the filter element 290, thereby improving the filtering effect of the mixed liquid.

[0032] In this embodiment, the mixing chamber 220 and the chamber cover 230 are hinged on one side, and a locking member 240 is provided on both sides of the mixing chamber 220 and the chamber cover 230. The locking member 240 includes a U-shaped mounting base 241, which is fixed to the side wall of the mixing chamber 220. A rotating shaft 242 is rotatably mounted on the U-shaped mounting base 241. Specifically, the rotating shaft 242 and the U-shaped mounting base 241 are configured to dampen rotation. A locking rod 243 is fixedly connected to the rotating shaft 242. The locking rod 243 can lock the mixing chamber 220 and the chamber cover 230. The sides of the mixing chamber 220 and the chamber cover 230 are each provided with a clearance groove that cooperates with the locking rod 243. Among them, when it is necessary to open the bin cover 230, the locking rod 243 is rotated outward, so that the rotating shaft 242 is rotated outward, so that the locking rod 243 leaves the two make way slots, and the bin cover 230 can be opened. When closing, the locking rod 243 is rotated again so that the locking rod 243 is located inside the two make way slots, thereby realizing the connection and locking of the bin cover 230 and the mixing bin 220.

[0033] In the specific setting, an elastic member 280 is arranged between the mixing bin 220 and the mounting plate 210. The elastic member 280 includes a first mounting block 281 and a second mounting block 282. The first mounting block 281 and the second mounting block 282 are respectively connected to the side walls of the mounting plate 210 and the mixing bin 220. A spring 283 is connected between the first mounting block 281 and the second mounting block 282.

[0034] The working principle of the desulfurization waste alkali liquor treatment tower:

[0035] The waste alkali liquor and neutralizing liquid generated by desulfurization simultaneously enter the mixing chamber 220 through the waste liquid inlet pipe 250 and the neutralizing liquid inlet pipe for mixing. The mixed waste liquid is filtered through the filter element 290 and then flows out through the liquid outlet hose 270 into the treatment tower 110. At the same time, the vibration motor 260 vibrates, which makes the mixed liquid mixing effect better. When the filter element 290 needs to be replaced, the chamber cover 230 can be opened to clean and replace it. The arrangement of the mixing chamber 220 and the filter element 290 allows the waste alkali liquor and the neutralizing liquid to be filtered and mixed in advance, thereby improving the treatment effect of the waste alkali liquor and saving the time of the waste alkali liquor treatment. The chamber cover 230 can be opened and arranged on the mixing chamber 220, making it convenient to replace and clean the filter element 290 and improving the filtering effect of the mixed liquid.

[0036] It should be noted that the specific model and specifications of the vibration motor 260 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principle of the vibration motor 260 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
