Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of acid mist recovery, in particular to a high-temperature acid mist recovery device. BACKGROUND

[0002] Acid mist is mainly generated in the process of using acid in industries such as chemical industry, electronics, metallurgy, electroplating, textile, and mechanical manufacturing, such as acid production, pickling, electroplating, electrolysis, and acid battery charging. Acid mist is a substance between flue gas and water mist. Since acidic substances have strong corrosive properties, acid mist also has strong corrosive properties. There are many types of acid mist. In order to treat acid mist well, it is necessary to adsorb and recover acid mist. Most existing high-temperature acid mist recovery devices use liquid absorption and solid absorption methods for recovery. Liquid absorption method has the disadvantages of poor recovery effect, low efficiency, high energy and water consumption, and inability to recover the heat generated by high-temperature acid mist. Solid absorption method has the disadvantages of limited adsorption capacity of adsorbent and intermittent operation. Therefore, solid adsorption method is only suitable for purifying waste gas with low acid mist concentration.

[0003] The patent with publication number CN114259829B provides a storage tank absorption acid mist recovery device. An air suction pump is fixedly installed on the recovery tank, which sucks acid mist into the recovery tank. An electric push rod drives a vertical screw to lift, and a threaded sleeve in the vertical screw rotates with a rotating drum, driving the spoiler to rotate synchronously, thereby achieving fast and stable flow disturbance, which is conducive to the adsorption of the inner adsorption sleeve and the bottom adsorption pad. At the same time, the flow disturbance mechanism can realize forward and reverse rotation, improving the flow disturbance effect. The lifting speed of the vertical screw controls the rotating speed of the flow disturbance mechanism, which is easy to control. However, this structure has limited adsorption capacity, intermittent operation, low efficiency, and is only suitable for purifying waste gas with low acid mist concentration, which has great limitations.

[0058] The working principle of the application is as follows: Figure 1 The use mode and corresponding scene of the application are given, the recovery function of high-temperature acid mist is determined by the cooling heat recovery device 1, the mechanical centrifugal separation device 2 and the pure water spray absorption device 4, the cooling heat recovery device 1 recovers heat in order to better form acid liquid droplets from high-temperature acid mist, to assist the gas-liquid separation of the mechanical centrifugal separation device 2, and the recovery and absorption efficiency of the pure water spray absorption device 4 is determined by the centrifugal efficiency of the mechanical centrifugal separation device 2, so the working posture of the mechanical centrifugal separation device 2 becomes the core.

[0059] For example, in Example One, the high-temperature acid mist enters the cooling tower body 105 from the acid mist input pipeline 107 of the cooling heat recovery device 1, is cooled and heat is recovered by the semicircular heat sink cover 108 and the mesh cooling cover 109, and forms acidic mist droplets and acidic gaseous substances, thereby completing the cooling and heat recovery functions. The acidic mist droplets and acidic gaseous substances enter the mechanical centrifugal separation device 2 from the cooling output pipeline 106, the transmission 213 drives the centrifugal inner cylinder 203 to rotate, thereby completing the gas-liquid separation function. The separated acidic liquid droplets are thrown into the centrifugal outer cylinder 202 by the centrifugal force, the eccentric wheel disc 206 drives the centrifugal outer cylinder 202 to vibrate, causing the liquid droplets to fall and collect in the centrifugal outer box 201, and then flow into the acid liquid recovery tank 5 from the centrifugal outer box 201, thereby completing the vibrating liquid droplet collection function.
