Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when on an element during " being provided with " another element, it can be directly can there is element placed in the middle on that element or also.When an element is considered to " connection " another element, it can be directly be communicated to another element, or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in specification sheets of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Refer to Fig. 1 ~ 2, the hydrochloric acid solution sealed cans of an embodiment, the second tank body 20 comprising the first tank body 10 and be embedded in the first tank body 10.
Wherein, degree of depth < second tank body 20 of 0.2 times of first tank body 10 is embedded in the degree of depth of degree of depth < 0.5 times of first tank body 10 in the first tank body 10.
The top of the first tank body 10 is provided with removable cover 12.Removable cover 12 is detachable, facilitates maintenance and inspection.
Removable cover 12 is provided with exhausr port 120.
Second tank body 20 is connected with the first tank body 10 by above-mentioned removable cover 12.
The bottom of the second tank body 20 has opening, and the second tank body 20 is communicated with the first tank body 10 by this opening.
The top of the second tank body 20 is provided with gas access 200.
In the present embodiment, the top of the second tank body 20 is provided with securing cover plate 22, and this securing cover plate 22 is provided with gas access 200.
Be appreciated that the outlet gas line of hydrochloric acid tank is communicated with the second tank body 20 by this gas access 200.
Concrete, outlet gas line and the gas access 200 of hydrochloric acid tank adopt Flange joint.
First tank body 10 is built with absorption liquid, and the bottom opening of the second tank body 20 is immersed in this absorption liquid.
When absorption liquid is water, absorbing the acid solution after hydrogen chloride can recycle, and improves economic benefit.When absorption liquid is alkali lye, the assimilation effect of hydrogen chloride is strengthened greatly, effectively prevent acid mist volatilization contaminated environment.
In the present embodiment, the first tank body 10 is also provided with liquidometer 16, for observing the liquid level of absorption liquid in the first tank body 10.
First tank body 10 is provided with fluid infusion mouth 100 near the side of removable cover 12, for adding absorption liquid.
First tank body 10 is provided with leakage fluid dram 110 near the side of bottom, for discharging the acid solution after absorbing hydrogen chloride.
Above-mentioned hydrochloric acid solution sealed cans, when adding hydrochloric acid in hydrochloric acid tank, along with the rising of hydrochloric acid liquid level, in storage tank, the hydrogen chloride gas of volatilization is compressed, enter in the second tank body 20 by gas access 200, absorbed by the absorption liquid of bottom, other non-absorbent gas then enters the top of absorption liquid in the first tank body 10, is discharged by exhausr port 120.Absorb that the acid solution after hydrogen chloride is then regular discharges from leakage fluid dram 110, recycle.
When hydrochloric acid tank extracts hydrochloric acid out, in hydrochloric acid tank, gas volume increase, pressure reduce, first tank body 10 is communicated with air by exhausr port 120, the gaseous tension in the first tank body 10 above absorption liquid is made to be greater than gaseous tension in the second tank body 20 above absorption liquid, under pressure reduction promotes, absorption liquid part in first tank body 10 enters in the second tank body 20, now air is in the form of bubbles along with absorption liquid enters in the second tank body 20, hydrochloric acid tank is entered again through gas access 200, thus keep hydrochloric acid tank internal pressure constant, avoid producing negative pressure.
When the liquid level of absorption liquid in the first tank body 10 be reduced to flush with the bottom opening of the second tank body 20 time, absorption liquid in first tank body 10 no longer enters in the second tank body 20, avoid the further increase of degree of vacuum in hydrochloric acid tank, absorption liquid now in the second tank body 20 has certain liquid level, under gravity, the absorption liquid in the second tank body 20 falls back in the first tank body 10.
It should be noted that, above-mentioned liquid seal can adopts resistant to corrosion non-metallic material to make, and cost is low.
Above-mentioned hydrochloric acid solution sealed cans, structure is simple, and easy to operate, good absorbing effect, equipment withstanding corrosion, cost is low.Adopt the second tank body to be embedded in design in the first tank body, both can absorb the hydrogen chloride gas evaporated in hydrochloric acid tank, prevent acid mist to volatilize contaminated environment, the pressure in hydrochloric acid tank can be balanced again, when effectively avoiding taking out hydrochloric acid, produce negative pressure.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
