A Diluter Low-set Ultrasonic Spray Tower

Abstract

A low-set ultrasonic spray tower with a diluter, including a tower body, a gas distributor is arranged at the top of the tower body, a circulating acid pipe is fixedly connected to the outside of the tower body, and a spray pipe is arranged in the tower body, and the circulating acid pipe passes through The circulating acid spray head is connected with the spray pipe, and it is characterized in that the spray pipe is evenly equipped with ultrasonic nozzles, and a sedimentation tank is arranged under the spray pipe, and the sedimentation tank is located in the middle section of the tower body, and a dilution tank is arranged below it. chamber, an expansion chamber is provided below the dilution chamber in the tower body, and a dilution acid tank is provided at the bottom of the tower body. The invention improves the uniformity of the sprayed liquid acid mist particles, the gas absorption efficiency is obviously high, the concentrated acid concentration accuracy after dilution is controlled within ±0.9%, the uniformity of the diluted acid is increased, the violent vibration of the diluter is effectively reduced, and the failure rate of the diluter is reduced by 30% %above. The invention expands the range of working conditions for acid concentration and acid temperature control in the process, and has good future economic benefits, huge market and broad industrialization prospect.

Description

technical field [0001] The invention relates to a dry suction dilution device for sulfuric acid production, in particular to a diluter-integrated spray tower in a waste heat recovery system. technical background [0002] At present, the low-temperature waste heat recovery spray tower mainly has the following disadvantages: 1. The spray droplet particles are relatively large, which causes erosion and corrosion of the spray pipe, and the efficiency of absorbing acid gas is low. 2. The diluter integrated spray tower has a simple structure, uneven dilution and violent reaction, which will affect the life of the equipment. Therefore a new solution should be provided to solve the above problems. Contents of the invention [0003] In order to solve the shortcomings of the traditional spray tower, the present invention provides a new type of diluter integrated spray tower structure - the ultrasonic spray tower with a low diluter, which solves the problem that the existing spray t...
