Description

Technical Field

[0001] The utility model relates to the technical field of spray recovery of tail gas, in particular to a spray recovery system for tail gas. Background Art

[0002] The tail gas left over from the PTA production process contains a large amount of organic matter, which contains a large amount of acetic acid. These tail gases are generally discharged into the atmosphere after simple treatment, thus affecting the air quality and polluting the environment.

[0003] The existing patent with publication number CN204147737U proposes a spray recovery system for exhaust gas. The recovery system includes an acetic acid spray tower and a water spray tower. The acetic acid spray tower is connected to the exhaust gas discharge pipe. The top of the side wall of the acetic acid spray tower is connected to an acetic acid liquid inlet pipe, and the bottom of the acetic acid spray tower is connected to a liquid outlet pipe. The top of the acetic acid spray tower is provided with an air outlet pipe, which is connected to the side wall of the water spray tower. The top of the side wall of the water spray tower is connected to a water inlet pipe. The bottom of the water spray tower is a liquid outlet pipe, and the top is connected to the exhaust gas treatment device through the exhaust gas discharge pipe.

[0004] Although the above-mentioned recovery system equipment processes the exhaust gas before discharge, it does not have the function of quickly disassembling and cleaning the filter plate when spraying and filtering the exhaust gas. Impurities and pollutants in the exhaust gas are easily attached to the filter plate after filtering for a long time. If not cleaned in time, it is easy to cause blockage, affecting the exhaust gas filtration and purification treatment, and reducing the recovery and treatment efficiency of the exhaust gas. In view of the above problems, we propose an improved and upgraded exhaust gas spray recovery system. Utility Model Content

[0005] The utility model aims to provide a spray recovery system for tail gas to solve the problems raised in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model device is provided with a fixing frame, a filter plate, a slider, a plug-in plate, a pressing buckle, a card slot cover, an insert rod and other components. The buckle is manually pressed to detach from the card slot cover, and then the plug-in plate is pulled out of the fixing frame by using the insert rod. At this time, the handle is pulled to slide the filter plate out of the slide groove on the fixing frame by using the slider. The filter plate can be quickly disassembled for cleaning, avoiding problems such as surface blockage caused by long-term use that affects exhaust gas treatment, which is beneficial to improving the stability of exhaust gas treatment recovery, and the result is simple.

[0015] 2. The utility model device is provided with components such as a spray tower, a circulation pump, a spray head, a demisting layer, and an activated carbon box. The circulation pump is driven to extract the medicine in the dosing barrel and the water inside the circulating water tank. The internal tail gas is deacidified by the spray head on the two brackets connected to the outer wall of the drainage frame. At this time, the deacidified tail gas passes through two filter plates and rises to the inside of the demisting layer. The tail gas is then transported to the inside of the activated carbon box through the air outlet for secondary adsorption of impurities. The purified tail gas is then discharged from the discharge pipe outlet by a blower. The tail gas can be fully purified and recycled, and the operation is simple.
