Abstract
The invention relates to improvement on a device for absorbing SO3 generated in the process of preparing sulfuric acid. The device is characterized in that: coolers are connected with circulation grooves of a primary absorption tower and a secondary absorption tower through pumps; the liquid inlet pipe of an absorption liquid distributing groove is connected with liquid outlet pipes of the two coolers; the bottom of the absorption liquid distributing groove is provided with two liquid drain pipes which are respectively connected with the liquid inlet pipes of the primary absorption tower and the secondary absorption tower; and the side wall of the upper part of the absorption liquid distributing groove is provided with an overflow pipe which is connected with the circulation grooves of the absorption towers. In the device for absorbing the SO3 generated in the process of preparing the sulfuric acid, two originally mutually independent systems are subjected to coordinated control, if one system goes wrong, the other system still can supply acid to the two systems, the capability of an absorption pump can be automatically improved to the maximum and the acid supply quantity of the two absorption towers can be ensured to the greatest extent, so that the absorption effect of the whole absorption process is ensured.
Description
Technical field
The present invention relates to a kind of SO for preparing sulfuric acid process
3The improvement of absorption unit.
Background technology
At sulfuric acid industry, absorption system technology has two kinds usually: a kind of is an absorption technique, and this technology is applicable to acid making system on a small scale; Another kind is twice absorption technique, and this technology is applicable to fairly large acid making system.Adopt the sulfate system of twice absorption technique at present; An absorption tower (be called for short one and inhale tower) and secondary absorption tower (be called for short two and inhale tower) all have separately independently recycle acid system usually; But in case the dried sucking pump of two any systems of recycle acid system breaks down, all can cause the system can not ordinary production, a large amount of emptyings of flue gas; Surrounding enviroment are caused detrimentally affect, then possibly cause industrial accident when serious.As, when a sucking pump is jumped car, can't go up acid once inhaling tower, through the SO in the flue gas of one, two, three layer of convertor conversion
3Inhale one and can not get in the tower absorbing, get into four layers of convertor then after because SO
3Concentration is too high can't proceed SO
2Conversion, after inhaling towers and absorb through two, the SO of emptying
2And SO
3Concentration all higher, environment has been caused secondary pollution; When two sucking pumps are jumped car, just can't be absorbed through the flue gas of four layers of conversion, so the SO in the flue gas of emptying
2And SO
3Concentration also higher.
Summary of the invention
The objective of the invention is to be directed against the deficiency that exists in twice absorption technique flow process in the above-mentioned prior art, provide a kind of flow process simple, easy to operate, can carry out the SO of the preparation sulfuric acid process of automatic chain control
3Absorption unit.
The objective of the invention is to realize in the following manner.
A kind of SO for preparing sulfuric acid process
3Absorption unit, its device comprises absorption tower and absorption tower circulation groove, secondary absorption tower and absorption tower circulation groove; It is characterized in that its structure also comprises:
Water cooler-this water cooler is the anodic protection water cooler, is two, connects through the pump configuration with the circulation groove on absorption tower and secondary absorption tower respectively;
Distribution trough-this distribution trough is a header tank to absorb liquid, and the drain pipe of its liquid-inlet pipe and two water coolers links; Absorption liquid distribution trough bottom is established two liquid discharging tubes and is linked with absorption tower and secondary absorption tower liquid-inlet pipe respectively; On absorption liquid distribution trough upper portion side wall, be provided with the upflow tube that links with the absorption tower circulation groove.
A kind of SO for preparing sulfuric acid process of the present invention
3Absorption unit; Be provided with a sulfuric acid absorption liquid divider; Recycle acid in the circulation groove on one-level and two absorption towers is protected water cooler through pump delivery to anode, after cooling, is delivered in the divider again, and is unified again to the concentrated confession acid in absorption tower and secondary absorption tower by divider; Be provided with on the acid delivering pipeline on divider to each absorption tower electric control valve with and pressure-measuring-point with so that regulate to supply the acid amount according to pressure; For the sake of security, in both sides, divider top an overflow spout is set respectively and leads in the circulation groove, when liquid level is too high in the divider, the vitriol oil can through overflow spout with get back to circulation groove separately, avoid emitting the groove accident.
A kind of SO for preparing sulfuric acid process of the present invention
3Absorption unit; Will be originally mutually independently two independently system carry out chain control; In case a system goes wrong, another system will supply acid still for two systems, and can be automatically that the capability improving of absorption pump is extremely maximum; Can guarantee the confession acid amount on two absorption towers most possibly, thereby guarantee the assimilation effect of whole absorption technique.

Embodiment
A kind of SO for preparing sulfuric acid process
3Absorption unit, its device comprises absorption tower 1 and absorption tower circulation groove 2, secondary absorption tower 3 and absorption tower circulation groove 4; Its structure also comprises:
Absorbing this distribution trough of liquid distribution trough 9-is a header tank, and the drain pipe 10,11 of its liquid-inlet pipe and two water coolers links; Absorption liquid distribution trough bottom is established two liquid discharging tubes 12,13 and is linked with absorption tower and secondary absorption tower liquid-inlet pipe respectively; Be provided with the upflow tube 14,15 that links with the absorption tower circulation groove in absorption liquid distribution trough upper portion side wall.
During ordinary production; Inhaling tower circulation groove and two toward one, to inhale implantation concentration in the tower circulation grooves be 92.5% the vitriol oil, starts one and inhale tower cyclic acid pump and two absorption tower cyclic acid pumps, sulfuric acid in the circulation groove is delivered to the cooling of anodic protection water cooler after; All get in the absorption liquid divider; Through after the secondary distribution respectively from the divider bottom go out acid tube from flowing into an absorption tower and two absorption towers, contact with from bottom to top flue gas adverse current in the tower, with SO wherein
3After the absorption, inhale flue gas that tower comes out from one and continue into that two absorption towers transform, inhale flue gas that towers come out through the tail gas funnel emptying from two; Automatic control motorized valve and tensimeter are installed on the liquid discharging tube 12, automatic control motorized valve and tensimeter are installed on the liquid discharging tube 13, the acid amount of advancing a suction tower and two suction towers is controlled and regulated.When a suction tower cyclic acid pump broke down, it was that two absorption towers confessions are sour that two suction tower cyclic acid pumps are just concentrated, and two absorption towers can be kept ordinary production basically in the short period of time; When two suction tower cyclic acid pumps break down, is that two absorption towers supply acid once inhaling the tower cyclic acid pump concentrated, ordinary production also can be kept basically in two absorption towers in the short period of time; The pump that breaks down can put into production use by rush repair.Like this,, do not influence normally carrying out of production, can not occur chimney yet and emit opium and environment is caused secondary pollution no matter fault appears in which pump.
