Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a fiberglass pickling tower with a waste gas recovery mechanism. Background Technology
[0002] In the production processes of industries such as chemical engineering, electroplating, and metallurgy, large amounts of waste gas containing acidic substances such as hydrochloric acid mist, sulfuric acid mist, and nitric acid mist are generated. Currently, fiberglass pickling towers are commonly used to treat these acidic waste gases. Existing fiberglass pickling towers generally purify the waste gas by spraying alkaline absorbent liquid and utilizing the packing layer for a neutralization reaction.
[0003] The existing FRP pickling towers have poor exhaust gas treatment performance, resulting in some exhaust gas being discharged directly without being fully absorbed and treated, thus causing environmental pollution.
[0004] To address these issues, we provide a fiberglass pickling tower with a waste gas recovery mechanism. Utility Model Content
[0005] The purpose of this invention is to provide a fiberglass pickling tower with a waste gas recovery mechanism, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass pickling tower with a waste gas recovery mechanism, comprising a pickling tower body, a recovery mechanism provided on the inner side of the pickling tower body, an observation and maintenance window provided on one side of the pickling tower body, and an air inlet provided on the outer side of the pickling tower body.
[0007] The recycling mechanism includes a first recycling component disposed inside the body of the pickling tower, and a second recycling component is disposed at one end of the first recycling component.
[0008] Preferably, the first recovery component includes a water tank disposed at the bottom of one side of the pickling tower body, a water pump fixedly connected to one side of the water tank, a conduit fixedly connected to the top of the water pump, a rotating atomizing nozzle rotatably connected to one end of the conduit, a grid plate fixedly installed on the inner wall of the pickling tower body, a dosing tank disposed on one side of the water pump, and an air guide pipe disposed at the top of the pickling tower body.
[0009] Preferably, the second recovery component includes a recovery box disposed at one end of the gas guide pipe, a condenser pipe disposed inside the recovery box, a condenser fixedly connected to one end of the condenser pipe, an activated carbon adsorption layer disposed directly below the condenser pipe, an air outlet fixedly connected to the bottom end of the recovery box, a pipe fixing bracket fixedly connected to the outside of the air outlet, and a fan disposed on one side of the air outlet.
[0010] Preferably, there are at least two sets of rotating atomizing nozzles, which rotate and atomize water under water pressure.
[0011] Preferably, there are at least two sets of grid plates, and the top of the grid plates is filled with filler material.
[0012] Preferably, the water pump is used to drive water circulation between the water tank and the rotating atomizing nozzle.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a first recovery component, where a water pump drives water from a tank to circulate to a rotating atomizing nozzle. Under water pressure, this forms a fine water mist, increasing the contact area between the waste gas and the water treatment medium, significantly improving the absorption efficiency of acidic gases. A multi-stage reaction layer is formed through the combination of a grid plate and filler material, extending the contact path between the waste gas and the atomized droplets, further enhancing reaction efficiency. A second recovery component, using a condenser tube and condenser, liquefies and recovers condensable organic matter from the waste gas, reducing pollutant emissions. Finally, an activated carbon adsorption layer adsorbs the remaining harmful gases, further improving the purification effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 As shown, a fiberglass pickling tower with a waste gas recovery mechanism includes a pickling tower body 1, a recovery mechanism 2 is provided on the inner side of the pickling tower body 1, an observation and maintenance window 3 is provided on one side of the pickling tower body 1, and an air inlet 4 is provided on the outer side of the pickling tower body 1. By setting the observation and maintenance window 3, the spraying status inside the device can be observed. At the same time, if a malfunction occurs, it can be disassembled for repair and replacement. By setting the air inlet 4, the waste gas can be effectively transported into the device.
[0022] The recycling mechanism 2 includes a first recycling component 21 disposed inside the pickling tower body 1, and a second recycling component 22 disposed at one end of the first recycling component 21.
[0023] Furthermore, the first recovery component 21 includes a water tank 211 located at the bottom of one side of the pickling tower body 1. A water pump 212 is fixedly connected to one side of the water tank 211, and a conduit 213 is fixedly connected to the top of the water pump 212. A rotating atomizing nozzle 214 is rotatably connected to one end of the conduit 213. A grid plate 215 is fixedly installed on the inner wall of the pickling tower body 1. A dosing tank 216 is located on one side of the water pump 212, and an air guide pipe 217 is located at the top of the pickling tower body 1. The water tank 211 is used to store the sprayed... The water required for rinsing is effectively circulated in the water tank 211 by the water pump 212. The water in the water tank 211 is introduced into the rotary atomizing nozzle 214 through the conduit 213. The rotary atomizing nozzle 214 increases the contact area between the exhaust gas and the water, significantly improving the absorption efficiency of acidic gases. The grid plate 215 extends the contact time of the atomized droplets, improving the reaction effect. The addition tank 216 allows for the targeted addition of neutralizing agents, enabling customized treatment of different acidic exhaust gases.
[0024] Furthermore, the second recovery component 22 includes a recovery box 221 disposed at one end of the gas guide pipe 217. A condenser pipe 222 is disposed inside the recovery box 221. A condenser 223 is fixedly connected to one end of the condenser pipe 222. An activated carbon adsorption layer 224 is disposed directly below the condenser pipe 222. An outlet is fixedly connected to the bottom end of the recovery box 221. A pipe fixing bracket 225 is fixedly connected to the outside of the outlet. A fan 226 is disposed on one side of the outlet. The recovery box 221 is used to install and fix the condenser pipe 222. The condenser pipe 222, in conjunction with the condenser 223, liquefies the condensable organic matter in the waste gas, reducing pollutant emissions. The activated carbon adsorption layer 224 can adsorb the remaining volatile organic matter. The pipe fixing bracket 225 enhances the structural stability of the system. The fan 226 provides continuous negative pressure to discharge the purified gas to the outside.
[0025] Furthermore, there are at least two sets of rotating atomizing nozzles 214. The rotating atomizing nozzles 214 rotate and atomize water under the action of water pressure. With this setting, the contact area is increased compared with traditional nozzles, ensuring that acidic gases are purified without dead angles.
[0026] Furthermore, there are at least two sets of grid plates 215, and the top of the grid plates 215 is filled with filler material. With this arrangement, when the exhaust gas passes through...
[0027] Furthermore, the water pump 212 is used to drive the water circulation between the water tank 211 and the rotating atomizing nozzle 214. This arrangement ensures that a stable closed loop is formed between the water tank 211 and the rotating atomizing nozzle 214, thus avoiding water waste in traditional open systems.
[0028] Working Principle: During operation, the exhaust gas pipe is first connected to the inlet 4, allowing the exhaust gas to enter the pickling tower body 1. Water pump 212 pumps water from water tank 211 through conduit 213 to the rotating atomizing nozzle 214, where it is sprayed out. Under the action of the grid plate 215 and the packing material, the contact time between the atomized droplets and the exhaust gas is extended, promoting a thorough neutralization reaction between the water and the exhaust gas. Different types of neutralizing agents can be added through the dosing tank 216 to accommodate acidic exhaust gases of varying properties. The pre-purified exhaust gas enters the recovery tank 221 through the guide pipe 217. With the synergistic action of the condenser pipe 222 and condenser 223, condensable organic matter in the exhaust gas is liquefied and recovered. Subsequently, the remaining exhaust gas undergoes secondary adsorption purification through the activated carbon adsorption layer 224. Finally, driven by the negative pressure of the fan 226, it is discharged from the equipment through the outlet, thus completing the operation of a fiberglass pickling tower with an exhaust gas recovery mechanism.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
