Abstract
The utility model relates to an acid-water mixer with a nozzle; the mixer is characterized in that: the section of a pressure acid nozzle is a funnel shape which is thick at the upper part and is thin at the lower part; a mixed acid jet flow channel at the upper section takes a conical shape, and the mixed acid jet flow channel at the lower section takes an inverted conical shape and runs through the mixed acid jet flow channel at the upper section, and a water jet flow channel is arranged at one side of the outer wall of an acid-mixing device. The mixer adopts vacuum technique, and under-pressure acid liquid is jet out by the pressure acid nozzle for forming high-speed jet, and vacuum is formed in the cavity of the conical acid-mixing device, thus leading sulphuric acid to be completely mixed with water and preparing sulphuric acid solution which is mixed uniformly with needed concentration. In addition, as jet speed is rapid in the acid and water mixing process, and the proportion of acid and water is high, the liberated heat is not enough to heat the water to boiling point in the mixing process, acid mist can not be generated and can not erode a water-adding area.
Description
Technical field
The utility model relates to the acid of a kind of band nozzle, water mixer, is applicable to add the water process in the gas washing in SA production.
Background technology
In the relieving haperacidity industry at home, dried desorption system adds water, and dual mode is arranged usually: promptly directly add water and add water by acid mixing device and mix.It is simple directly to add water mode structure and Process configuration, generally is used for sulphuric acid process, but this to add the problem that the water mode exists more, mainly shows following several respects:
A, add water and concentrate, acid, water mix inhomogeneous, cause local high heat boiling, produce a large amount of acid mists and steam and cause equipment corrosions such as circulation groove lid and groove face adapter;
B, when the recycle acid temperature is too high, to Corrosion of Pipeline aggravation, cause product vitriolic quality instability, the consumption of material accessory increases;
Acid mist that produces in c, the mixing process and steam may cause liquidometer malfunctioning, produce system misoperation:
D, acid mist and steam cause the circulation groove deaeration pipe to be with acid in a large number, improve the material requirement to deaeration pipe greatly;
Liquid level localized hyperthermia and diluted acid cause local corrosion to recycle pump and tubular stinger in e, the groove;
F, filler pipe corrosion-vulnerable, work-ing life is shorter.
Summary of the invention
Directly add water and add the problem that water exists by acid mixing device at existing, the purpose of this utility model aims to provide the acid of a kind of band nozzle, water mixer.It utilizes the principle of water-jet pump, fundamentally solves dried in the past desorption system and adds the problem that exists in the water conservancy project skill.
The purpose of this utility model can realize by following measure;
The acid of a kind of band nozzle, water mixer are made up of pressure acid nozzle, water jet passage, epimere nitration mixture fluidic channel, hypomere nitration mixture fluidic channel and acid mixing device outer wall.Pressure acid nozzle section is up big and down small funnel shaped, and epimere nitration mixture fluidic channel is coniform, and hypomere nitration mixture fluidic channel is the coniform of handstand, and connects with epimere nitration mixture fluidic channel, and acid mixing device outer wall one side is provided with the water jet passage.
Above-mentioned pressure acid nozzle cone angle is 10 °-15 °
The beneficial effect of advantage of the present utility model and generation is:
(1) the utility model adopts vacuum technique.Band presses acid solution spouting through excess pressure acid nozzle a, forms high-speed jet, forms " vacuum " and bring water into mixing in the acid mixing device cavity, can save energy and reduce the cost, accelerate acid, water mixing velocity, improves the quality of products, increases economic benefit.
(2) can finish at short notice owing to the nitration mixture process, adopt coniform nitration mixture fluidic channel, mixed acid is discharged from the nitration mixture fluidic channel rapidly, can avoid above-mentioned dried desorption system directly to add water and acid mixing device in the past and add the acid mist that produces in the water and steam, reduce processing cost greatly the etching problem of nitration mixture equipment.
(3) determined acid, water blending ratio, just can control the amount that enters water easily by the internal diameter of regulating sour flow, flow velocity, pipeline.Promptly under the prerequisite of constant rate of acid, water, by regulating the amount of acid, regulate the cavity negative pressure, by the variation of negative pressure, the water yield that indirect adjusting enters guarantees that water is inexcessive, guarantees that temperature and concentration do not have acute variation.Thereby solve the corrosive problem, guaranteed the quality of finished acid.
(4) the utility model overcurrent partly adopts high temperature resistant, erosion resistance material, and all the other not corrosion resistant parts should prevent to be corroded.The material of its flow passage components has: pottery, plain cast iron, high silicon cast iron, stainless steel, high quality steel, titanium and alloy thereof etc.Can increase the service life.
(5) the utility model is simple in structure, for ease of maintenaince, change.

Fig. 2 is acid, water hybrid technique schema
Among the figure: 1. acid, water mixer, 2. plate cooler, 3. vitriolic acid flux variable valve, 4. sulphuric acid soln pipeline, 5. water control valve, 6. water inlet pipe
Embodiment
Below in conjunction with accompanying drawing invention is further described again:
As shown in Figure 1 and Figure 2, the flow velocity of ingress sulphuric acid soln should be controlled at 0.001-1m
3/ s, operating pressure is 101.3kPa.Make 98.5% concentrated sulfuric acid solution after purify absorbing and be cooled to 60 ' C through plate cooler 2, band presses acid solution to pass through sulphuric acid soln pipeline 4 under the adjusting of vitriolic acid flux variable valve 3, the pressure acid nozzle a that sends into acid, water mixer 1 with the speed of 150T/h is spouting, form high-speed jet, pressure acid nozzle a cone angle is 12 °.Flow velocity is by being subjected to 3 controls of vitriolic acid flux variable valve on the acid mixing device inlet acid tube road, form parital vacuum in pressure acid nozzle a exit, cause this partial pressure to be lower than by the pressure of drinking-water pipe water, under the effect of this pressure difference, the water control valve 5 control water yields, the water in the water pipe is by injection, and discharge is that 5T/h is through water inlet pipe 6, water jet passage b, enter the nitration mixture fluidic channel c section of acid, water mixer 1, and then mix with acid solution.Acid, when water mixed liquid enters the fluidic channel c section of acid, water mixer 1, be subjected to cushioning the effect of diffusion, jet speed reduces, pressure increases, penetrate through fluidic channel d section again, make sulfuric acid and water thorough mixing to make the desired concn sulphuric acid soln that mixes.Mixed acid concentration is 95.3%, and temperature out is 92.5 ℃.
Because acid, water mixing process jet speed is very fast, and the sour water ratio is very big, and liberated heat is not enough to water is heated to boiling point in the mixing process, therefore can not generate acid mist, the minute quantity acid mist that generates is also brought in the acid solution by jet flow negative pressure, adds to absorb circulation, can not cause corrosion to adding the pool.
Should avoid under low discharge, working aggravation corrosion during operation in order to avoid fluid temperature raises.
It is that 100-120 ℃ cast steel material is made that flow passage components are selected anti-concentrated acid temperature for use.
