Abstract
The utility model discloses a jet pump applied to the wet desulphurization forced-oxidization. The utility model includes a nozzle 5, a pipe inlet 2, a pipe 3, a diffusing pipe 7, a tail pipe 8 and an air suction pipe 1. The utility model is characterized in that a current disturber 6 is fixed on the inner wall of the pipe 3, and the current disturber 6 is produced into a spiral shape. The design of the utility model is more rational, the air suction volume is larger, the contact area of the two phrases of the gas and liquid is increased, the increase of the oxygen utilization rate is facilitated, the oxygen can be effectively charged, and the operating energy consumption is lowered.
Description
Technical field
The utility model belongs to a kind of environment protection desulphurization technical field, specifically, is the Jet injector of using in a kind of wet desulphurization forced oxidation.
Background technique
Two kinds of forms of forced oxidation and autoxidation are arranged in the limestone wet-process flue gas desulfurization technique, in the autoxidation technology because problems such as fouling and obstruction often take place, influence the normal operation of whole system, thus at present in the world wet desulfurizing process mainly based on forced oxidation.
The forced oxidation system mostly relies on blower fan or air compressor as the forced oxidation air power source, blasts air in lime stone slurry; Recycling for slurries, need add the slurries circulatory system.The forced oxidation systematic comparison is stable, and adaptability is extensive, but has equipment complexity, big, the shortcomings such as occupation of land is many, coefficient of oxygen utilization is low, operating cost is high, capital investment is big, noise is high, maintenance management difficulty of structure volume.For overcoming above-mentioned shortcoming, adopted lime stone slurry jet oxidation technology in the foreign department branch engineering, this technology utilizes lime stone slurry as working fluid exactly, entrainment air by Jet injector and enter the slurries pond with slurries, in the slurries pond under the well-off situation of oxygen, the oxidation fan of can stopping transport so reduced operating cost, can save energy about 20%.
The Jet injector that uses in the jet oxidation technology comprises jet pipe now, this Jet injector top is that funnel shape, middle part are cylindrical, the bottom is conical, the funnel shaped sidewall on described Jet injector top is communicated with air intake pipe, stretched into nozzle from described Jet injector top, have following shortcoming: gettering quantity is few, and air mixes inhomogeneous with lime stone slurry, Jet injector outlet bubble is bigger, this has reduced the area of contact of gas-liquid two-phase, and the utilization ratio of oxygen reduces, and has increased operation energy consumption.
The model utility content
Technical problem to be solved in the utility model is to provide the Jet injector of using in the wet desulphurization forced oxidation that a kind of gas-liquid two-phase area of contact is big, band tolerance is sufficient, oxygen transfer efficiency is high.
The technical solution of the utility model is as follows: the Jet injector of using in the wet desulphurization forced oxidation, comprise nozzle, trunnion inlet, trunnion, diffusing tube, tail pipe and air intake pipe, its key is: be fixed with turbolator on the inwall of described trunnion, this turbolator is made helical.Lime stone slurry through pressurization is injected trunnion at a high speed from nozzle, high-speed liquid can produce negative pressure when flowing through the trunnion inlet herein, entrainment the air in air intake pipe and the hollow tubular, air that is entrainmented and lime stone slurry fully mix in trunnion, spray into the limestone slurry liquid pool through tail pipe, oxidation air is provided, replenishes lime stone slurry.Described jet pipe middle part trunnion is installed turbolator, when gas and liquid mixture is flowed through herein, produces gas-liquid high speed whirlpool, blending, air is divided into countless micro-bubbles, these micro-bubbles have increased the area of contact of gas-liquid two-phase, help improving coefficient of oxygen utilization, have reached the purpose of efficient oxygenation.
Described air intake pipe is drawn a hollow tubular, and the one end is fixed on the described air intake pipe outer wall, and the sidewall that the other end passes nozzle enters in this nozzle, and its termination is extended down to the nozzle of described nozzle.The hollow tubular diameter is 10～30% of an orifice size.In nozzle, increase hollow tubular, the portion of air of air intake pipe is delivered to nozzle, can increase the area of contact of gas-liquid two-phase, increase the air-breathing area and the gettering quantity of Jet injector simultaneously, the hollow tubular diameter is designed to 10～30% of orifice size and reaches above-mentioned better effects if.
Described turbolator is made with steel, and length is 30～50% of length of throat, and Thickness Design is 1mm.Design is more reasonable like this, and effect is better.
Beneficial effect: it is big to the utlity model has gettering quantity, and air mixes more even with lime stone slurry, and Jet injector outlet bubble is cut into micro-bubble, increased the area of contact of gas-liquid two-phase, help improving coefficient of oxygen utilization, reached the purpose of efficient oxygenation, reduced operation energy consumption.
