Abstract
The utility model discloses a sulfur trioxide bearing tail gas absorption device which comprises an absorption tower and a sulfur trioxide reaction tower; the interior of the absorption tower is divided into an upper alkali tank and an neutralization tank by a partition board; a sprinkler head is arranged on the partition board; a circulation pipe is arranged at the upper part of the neutralization tank; a gas delivery pipe is arranged at the lower part of the neutralization tank; the gas delivery pipe is communicated with the sulfur trioxide reaction tower; and the circulation pipe is communicated with the gas delivery pipe. The sulfur trioxide bearing tail gas absorption device provided by the utility model has the advantages of simple structure, easiness in accomplishment, convenience in installation and maintenance, and strong tail gas absorption effect, and effectively reduces the gas pollution caused during the process of making concentrated sulphuric acid by sulfur trioxide.
Description
Technical field
The utility model relates to concentrated sulfuric acid process units field, is specially a kind of sulfur trioxide device for absorbing tail gas.
Background technology
The sulfuric acid of high concentration is a kind of industry raw materials for production commonly used, and as can being used as the electrolyte of electromobile battery, the gas washing in SA production of high concentration generally is that the sulfuric acid through sulfur trioxide and low concentration reacts and obtains.In the tail gas behind sulfur trioxide and the sulfuric acid reaction, contain acid pollution gas, therefore need absorb, pollute in order to avoid directly be disposed to atmosphere to tail gas.
The utility model content
The utility model purpose provides a kind of sulfur trioxide device for absorbing tail gas, with the problem of tail gas absorption behind solution sulfur trioxide and the gas washing in SA production high-concentration sulfuric acid.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The sulfur trioxide device for absorbing tail gas; It is characterized in that: the sulfur trioxide reaction tower that comprises absorption tower, magnetic tape trailer gas outlet; Separated by dividing plate in the said absorption tower and be the alkali pond on top and the neutralization pond of bottom, the sprinkler head that sprays to neutralization pond is installed on the said dividing plate, be positioned at the neutralization pond upper portion side wall circulation pipe is installed; The neutralization pond lower sides is equipped with appendix; Said appendix is communicated to sulfur trioxide reaction tower tail-gas outlet, and said circulation pipe is communicated on the said appendix, and on the said circulation pipe aspiration pump is installed.
The utility model is simple in structure, is easy to realize, installation and maintenance is convenient.Carrying out tail gas through the absorption tower that is communicated with sulfur trioxide reaction tower tail-gas outlet absorbs; The absorption tower is divided into alkali pond and neutralization pond by dividing plate; Acid tail gas feeds in the neutralization pond; Through sprinkler head the alkaline matter in the alkali pond is sent into the acid tail gas of neutralization in the neutralization pond, the gas circulation after circulation pipe will neutralize is simultaneously sent in the neutralization pond, guarantees that sour gas is by neutralization fully.The circulating tail gas assimilation effect of the utility model is stronger, has alleviated the gaseous contamination that the sulfur trioxide system concentrated sulfuric acid causes effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1.The sulfur trioxide device for absorbing tail gas comprises the sulfur trioxide reaction tower 3 of absorption tower 1, magnetic tape trailer gas outlet 2, is separated the neutralization pond 5 of the alkali pond 4 and the bottom that are top in the absorption tower 1 by dividing plate; The sprinkler head 6 that sprays to neutralization pond is installed on the dividing plate; Be positioned at neutralization pond 5 upper portion side wall circulation pipe 7 is installed, neutralization pond 5 lower sides are equipped with appendix 8, and appendix 8 is communicated to sulfur trioxide reaction tower 3 tail gas outlets 2; Circulation pipe 7 is communicated on the appendix 8, and on the circulation pipe 8 aspiration pump 9 is installed.
