技术领域Technical Field
本实用新型属于废气处理设备领域，具体涉及一种橡胶废气处理用喷淋塔。The utility model belongs to the field of waste gas treatment equipment, and specifically relates to a spray tower for treating rubber waste gas.
背景技术Background Art
喷淋塔是通过喷淋吸收塔的冷却、吸收、过滤和洗涤，以达到废气的降温、过滤作用的废气处理设备。轮胎制造、废旧轮胎加工等橡胶工业生产过程中会产生大量的橡胶废气，通常需要用到喷淋塔来进行废气处理。现有的喷淋塔都是采用废气自下而上、喷淋水自上而下的对流设置，为了提高废气与喷淋水的接触面积，喷淋塔内部一般设置有多层填料，设备结构相对比较简单，普遍存在的主要通病就是排放气体中的含水量大，而且填料使用寿命短，废气处理效率低，净化不够彻底；另外，针对橡胶工业废气即便经过喷淋塔洗涤，排空废气中依然带有一股胶皮异味，对于周围环境内的居民生活会造成一定的影响。因此，亟需对现有喷淋塔进行进一步的改造和完善。The spray tower is a waste gas treatment equipment that achieves the cooling and filtering effects of waste gas through the cooling, absorption, filtering and washing of the spray absorption tower. A large amount of rubber waste gas will be generated in the rubber industry production process such as tire manufacturing and waste tire processing, and a spray tower is usually required for waste gas treatment. The existing spray towers all adopt the convection setting of waste gas from bottom to top and spray water from top to bottom. In order to increase the contact area between the waste gas and the spray water, the spray tower is generally equipped with multiple layers of fillers. The equipment structure is relatively simple. The main common problem is that the water content in the exhaust gas is large, and the service life of the filler is short, the waste gas treatment efficiency is low, and the purification is not thorough enough; in addition, even if the rubber industrial waste gas is washed by the spray tower, the exhaust gas still has a rubber smell, which will have a certain impact on the lives of residents in the surrounding environment. Therefore, it is urgent to further transform and improve the existing spray tower.

橡胶废气经切线进气口进入旋风分离器，形成螺旋状气旋，再携带上所述喷淋嘴喷出的高压水雾，进一步形成气动水旋，与此同时废气中的部分粉尘粒子与水雾充分接触融合进而形成体积、质量较大的混合液滴，又在离心力作用下甩向旋风分离器内壁并经底部沉降排液口流下，经所述锥形底汇聚最终回收至循环水箱内。同时经过初步洗涤后的废气由顶部分离出气口排出，再经导气间隙变向引导起到一定的气流缓冲作用，最后经底部进气口进入填料塔，改变了传统喷淋塔直接底部进气、顶部出气的直线式气液对流洗涤，极大地有利于减少排放废气中的含水量。气流在通过各填料层之前先经旋流板引导形成漩涡状气流，再经填料层不同类型的填料，使得上升气流与所述喷淋头的下喷水雾形成更加充分的对流接触，进一步完成对橡胶废气的充分洗涤。经过充分洗涤净化后的废气再经除雾器进一步降低废气中的含水量，再经除异味吸附床对橡胶废气中的胶皮异味分子进行吸附除味，最终由填料塔顶部出气口排出喷淋塔系统，如果除异味效果仍不够理想，还可以在排空管道上适当增设抽屉式活性炭吸附箱等环保设备对排空废气进行更加彻底的净化处理。The rubber waste gas enters the cyclone separator through the tangential air inlet, forming a spiral cyclone, and then carries the high-pressure water mist sprayed from the spray nozzle to further form a pneumatic water cyclone. At the same time, some dust particles in the waste gas fully contact and fuse with the water mist to form mixed droplets with large volume and mass, which are thrown to the inner wall of the cyclone separator under the action of centrifugal force and flow down through the bottom sedimentation discharge port, converge through the conical bottom and finally recovered into the circulating water tank. At the same time, the waste gas after preliminary washing is discharged from the top separation outlet, and then guided by the air guide gap to play a certain air flow buffering role, and finally enters the packing tower through the bottom air inlet, which changes the linear gas-liquid convection washing of the traditional spray tower with direct bottom air intake and top air outlet, which is greatly beneficial to reduce the water content in the discharged waste gas. Before passing through each packing layer, the air flow is first guided by the swirl plate to form a vortex air flow, and then passes through different types of fillers in the packing layer, so that the rising air flow and the lower spray water mist of the spray head form a more sufficient convection contact, further completing the full washing of the rubber waste gas. The exhaust gas after sufficient washing and purification is then passed through a demister to further reduce the water content in the exhaust gas, and then passed through an odor removal adsorption bed to adsorb and remove the rubber odor molecules in the rubber exhaust gas, and finally discharged from the spray tower system through the air outlet at the top of the packing tower. If the odor removal effect is still not ideal, environmental protection equipment such as drawer-type activated carbon adsorption boxes can be appropriately added to the exhaust pipe to purify the exhaust gas more thoroughly.
本实用新型的技术方案并不限于上述具体实施例的限制，在不偏离所说明实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的，凡在本实用新型的精神和原则之内，所作的任何技术变形，均落入本实用新型的保护范围之内。The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the protection scope of the present invention.
