Ultraphonic spray tower with low-placed dilution device

Abstract

The invention provides an ultraphonic spray tower with a low-placed dilution device. The spray tower includes a tower body. A gas distributor is disposed on the top of the tower body, circulatory acid pipes are fixedly connected outside the tower body, and shower pipes are disposed inside the tower body. The circulatory acid pipes communicate with the shower pipes with circulatory acid sprayers. The spray tower is characterized in that ultraphonic nozzles are uniformly disposed on the shower pipes, a depositing tank is disposed below the shower pipes wherein the depositing tank is placed in the middle of the tower body, a dilution chamber is disposed under the depositing tank, an enlargement chamber is disposed below the dilution chamber, and a dilution acid tank is disposed at the bottom of the tower body. The spray tower improves the uniformity of spraying liquid acid mist particle, improves the gas absorption rate obviously, controls the accuracy range of concentrated acid concentration after dilution is + / - 0.9%, increases the uniformity of dilution acid, reduces the strenuous vibration of the diluter effectively, and reduces the failure rate of the diluter more than 30%. The control of the working-condition range for acid concentration and acid temperature in the technology is enlarged, and the spray tower has good economic benefit in future, huge market, and wide industrial 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...
