Description
技术领域technical field
本实用新型涉及废气处理设备领域，尤其是一种烟道废气的喷淋洗涤系统。The utility model relates to the field of waste gas treatment equipment, in particular to a spray washing system for flue waste gas.
背景技术Background technique
喷淋洗涤塔在环保等领域应用广泛。常规的喷淋洗涤塔只是将烟道废气通入洗涤塔后利用吸收塔上端的喷淋头进行喷淋洗涤，然后再通过除雾器处理后将废气排出，其喷淋洗涤效果差。Spray scrubbers are widely used in environmental protection and other fields. Conventional spray scrubbers just pass the flue exhaust gas into the scrubber and use the spray head on the upper end of the absorption tower to spray and wash, and then discharge the exhaust gas after being treated by a demister, which has a poor spray scrubbing effect.
实用新型内容Utility model content
本实用新型的目的是为了解决上述技术的不足而提供一种能有效的提高洗涤和降温效果的烟道废气的喷淋洗涤系统。The purpose of this utility model is to provide a flue exhaust gas spray washing system that can effectively improve the washing and cooling effect in order to solve the above technical deficiencies.
为了达到上述目的，本实用新型所设计的一种烟道废气的喷淋洗涤系统，它包括喷淋洗涤塔、除雾器、工艺水箱和浆液箱，所述的除雾器设置在喷淋洗涤塔内部的上端，所述的除雾器通过管道和冲洗水泵与工艺水箱连接，所述的浆液箱通过管道和浆液泵连接至喷淋洗涤塔内部，在喷淋洗涤塔的中下部的侧壁上设置有一个进气烟道，在进气烟道内设置有若干个喷淋头，在进气烟道与除雾器之间的喷淋洗涤塔内部设置有若干个喷淋头；所述的各个喷淋头通过管道连接至喷淋洗涤塔的底部，且在该管道上设置有循环泵；在喷淋洗涤塔底部设置有排出泵；在喷淋洗涤塔的顶部设置有出气烟道。In order to achieve the above purpose, a spray washing system for flue exhaust gas designed by the utility model includes a spray washing tower, a demister, a process water tank and a slurry tank, and the demister is arranged in the spray washing At the upper end of the tower, the demister is connected to the process water tank through a pipeline and a flushing water pump, and the slurry tank is connected to the inside of the spray scrubber through a pipeline and a slurry pump, and the side wall of the middle and lower part of the spray scrubber An intake flue is arranged on the top, several spray heads are arranged in the intake flue, and several spray heads are arranged inside the spray scrubber between the intake flue and the mist eliminator; Each spray head is connected to the bottom of the spray scrubber through a pipeline, and a circulation pump is arranged on the pipeline; a discharge pump is arranged at the bottom of the spray scrubber; and an outlet flue is arranged at the top of the spray scrubber.
所述的进气烟道位于喷淋洗涤塔的外部，且与喷淋洗涤塔的中部连通，位于进气烟道内的喷淋头的喷淋方向与进气烟道内的废气流动方向一致。该技术方案，适合较低浓度的浆液，循环浆液从塔底抽出打入到设置在喷淋洗涤塔上的进气烟道内的喷淋头，在一个相对集中的空间内充分的混合。由于浆液、烟气与烟道壁会发生碰撞，湍流现象较为强烈，能起到较好的预洗涤效果。随后烟气和浆液导入到塔内，烟气再次与塔上部喷下的浆液相混合，发生二次洗涤。此方案的烟道进口段较短，且在塔主体外，所以结构上相对简单，只适合于浓度较低的循环浆液。浆液浓度一般在1.05 t/m3以下适用。The air intake flue is located outside the spray scrubber and communicates with the middle of the spray scrubber, and the spraying direction of the spray head located in the air intake flue is consistent with the flow direction of the exhaust gas in the air intake flue. This technical solution is suitable for slurry with a relatively low concentration. The circulating slurry is pumped from the bottom of the tower and poured into the spray head in the air inlet flue arranged on the spray scrubber, where it is fully mixed in a relatively concentrated space. Because the slurry, flue gas and the flue wall will collide, the turbulence phenomenon is relatively strong, which can have a better pre-washing effect. Then the flue gas and slurry are introduced into the tower, and the flue gas is mixed with the slurry sprayed from the upper part of the tower again, and secondary washing occurs. The flue inlet section of this scheme is relatively short and outside the main body of the tower, so the structure is relatively simple, and it is only suitable for circulating slurry with low concentration. The slurry concentration is generally applicable below 1.05 t/m 3 .
所述的进气烟道从喷淋洗涤塔的中部进入喷淋洗涤塔后竖直向下延伸，且进气烟道的最下端高于喷淋洗涤塔内部的液面；位于进气烟道内的喷淋头处于进气烟道竖直向下的部分内部，且该喷淋头的喷淋方向竖直向上。该技术方案，适应于浓度中等的浆液，有一个伸到塔内部的烟道延伸段。该延伸段主体延伸方向向下，喷淋方向则向上，可以起到相向对冲、交流效果。能使烟气和浆液颗粒间的湍流混合得到大幅加强、洗涤降温更为充分。由于该延伸段是直管结构，能帮助浆液更好的向下扩散，延缓管道壁结垢现象的发生。浆液浓度一般在1.05 t/m3以上适用。The air intake flue extends vertically downward after entering the spray scrubber from the middle of the spray scrubber, and the lowermost end of the air intake flue is higher than the liquid level inside the spray scrubber; it is located in the air intake flue The spray head is located inside the vertically downward part of the air intake flue, and the spray direction of the spray head is vertically upward. This technical scheme is suitable for slurry with medium concentration, and has a flue extension section extending to the inside of the tower. The extending direction of the main body of the extension section is downwards, and the spraying direction is upwards, which can achieve opposite hedging and communication effects. The turbulent mixing between flue gas and slurry particles can be greatly enhanced, and the washing and cooling can be more sufficient. Since the extension section is a straight pipe structure, it can help the slurry to diffuse downwards better and delay the occurrence of scaling on the pipe wall. The slurry concentration is generally applicable above 1.05 t/m 3 .
所述的进气烟道为喷淋洗涤塔的一部分，且位于喷淋洗涤塔的侧边，进气烟道为竖直向下，进气烟道的中上部与喷淋洗涤塔隔开，进气烟道的底端与喷淋洗涤塔连通，位于进气烟道内的喷淋头的喷淋方向竖直向上。该技术方案适合浓度较高的浆液，其延伸段改成为与塔身一体化的设计，这样可以使得延伸段内部空间更大，在建造施工和日常维修上更为便利。浆液浓度一般在1.15 t/m3以上适用。The air intake flue is a part of the spray scrubber, and is positioned at the side of the spray scrubber, the air intake flue is vertically downward, and the middle and upper part of the air intake flue is separated from the spray scrubber, The bottom end of the intake flue communicates with the spray scrubber, and the spraying direction of the spray head located in the intake flue is vertically upward. This technical solution is suitable for slurry with high concentration, and its extension section is changed to an integrated design with the tower body, which can make the interior space of the extension section larger and facilitate construction and daily maintenance. The slurry concentration is generally applicable above 1.15 t/m 3 .
所述的冲洗水泵、浆液泵、循环泵、排出泵均为两台并联，一台运行、一台备用。也可以都设置为单台或多台并联的型式。The flushing water pump, the slurry pump, the circulation pump and the discharge pump are all connected in parallel, one is running and the other is standby. It can also be set as a single or multiple parallel models.
本实用新型所得到的一种烟道废气的喷淋洗涤系统，其在进气烟道内设置喷淋头，加强烟气也浆液颗粒之间的湍流和碰撞作用，从而有利于提高洗涤、降温的效率；而且通过两次洗涤、强弱配合的方式，进一步保证了洗涤的充分和可靠，同时基本不增加洗涤塔的阻力，更加节能环保。A spray washing system for flue exhaust gas obtained by the utility model, which is provided with a spray head in the intake flue, strengthens the turbulent flow and collision between the flue gas and the slurry particles, which is beneficial to improve the efficiency of washing and cooling Efficiency; and through two washings and the combination of strength and weakness, it further ensures that the washing is sufficient and reliable, and at the same time basically does not increase the resistance of the washing tower, which is more energy-saving and environmentally friendly.
