Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Incorporated by reference to see Fig. 1 and Fig. 2, the invention provides and be installed on hydrochloric acid tank exhausr port or/and the breathing valve of pneumostome.Breathing valve is circular.Breathing valve comprises the body cap 110 that valve body 120 that inside has cavity coordinates with valve body 120 and the tightening seal washer 130 be sandwiched between valve body 120 and body cap 110.Raised line 123 is set in valve body 120, the cavity of valve body 120 is divided into the first cavity 121 and the second cavity 122.In all holding in first cavity 121 and the second cavity 122 and hydrochloric acid solution, as sodium hydroxide solution, water etc.Holding solution in preferred first cavity 121 is water, and holding solution in the second cavity 122 is alkaline solution.The consumption of alkali lye can be saved, the solution in the first cavity 121 can be made again to become hydrochloric acid solution.The region that body cap 110 is corresponding with the first cavity 121 is provided with the downtake pipe 111 be communicated with the first cavity 121.Downtake pipe 111 can to stretch in the first cavity 121 but not to submerge in liquid, can discharge to enter the first cavity 121 gas from downtake pipe 111.First cavity 121 is communicated with by communicating pipe 112 with the second cavity 122, and communicating pipe 112 is installed on body cap 110.Communicating pipe 112 can be communicating pipe, also can be communicated with the pipeline of the first cavity 121 and the second cavity 122 for any other.The first end of communicating pipe communicating pipe 112 submerge solution in the first cavity 121 liquid level under, the gas of the second cavity 122 imported in the first cavity 121 and in hydrochloric acid solution, fully to react with it, acid mist is neutralized.Second end of communicating pipe 112 then stretches into the second cavity 122 but in the solution do not submerged in the second cavity 122, to be exported in the second cavity 122 by the gas in the first cavity 121.Body cap 110 is fixedly connected with by screw with valve body 120, and is clamped by tightening seal washer 130 to realize sealing.
The air inlet pipe 124 be communicated with hydrochloric acid tank inside is installed in the bottom of the second cavity 122 of valve body 120.Air inlet pipe 124 is straight tube, the first end of air inlet pipe 124 stretches in the second cavity 122, and this first port higher than in and the liquid level of hydrochloric acid solution, in case in and hydrochloric acid solution pour in down a chimney from air inlet pipe 124 and enter in hydrochloric acid tank, in and hydrochloric acid in hydrochloric acid tank affect its quality.On the exhausr port that second end of air inlet pipe 124 is fixed on hydrochloric acid tank by flange or breathing valve, so that make the gases such as the acid mist in hydrochloric acid tank be entered in the second cavity 122 by air inlet pipe 124.The first end of air inlet pipe 124 and second side of communicating pipe 112 are arranged for staggering.The contact time that can increase neutralization solution in acid mist and the second chamber 122 is set like this, prevents the acid mist entering the second cavity 122 from air inlet pipe 124 from directly entering communicating pipe 112.On the body cap 110 of corresponding second cavity 122, there is also mounted first end and to submerge the second exhaust pipe 113 of solution in the second cavity 122.Second end of second exhaust pipe 113 stretches out valve body 120 and is communicated with air.The first end of second exhaust pipe 113 solution that submerges can prevent the acid mist entering the second chamber 122 from air inlet pipe 124 directly emptying.
Please refer to Fig. 3, particularly, in the present embodiment, tightening seal washer 130 comprises annulus and the symmetrical vertical bar separating annulus.Tightening seal washer 130 coordinates with valve body 120 periphery and raised line 123.Tightening seal washer 130 can, by the first cavity 121 and the second cavity 122 seal isolation in valve body 120, make the first cavity 121 can only be communicated with by communicating pipe 112 with the second cavity 122.
Incorporated by reference to Fig. 4 and Fig. 5, hydrochloric acid tank comprise tank body 200, multiple be arranged at sidewall bottom tank body 200 discharging opening 210, be multiplely symmetricly set in the inlet point 221 at tank body 200 top, the first manhole 231 being arranged at center, tank body 200 top, the second manhole 232 being arranged at sidewall bottom tank body 200 and multiple liquidometer hole 241 being arranged at tank body 200 sidewall.
4 liquidometer holes 241 are preferably set, comprise the first liquidometer hole, the second liquidometer hole, the 3rd liquidometer hole and the 4th liquidometer hole.First liquidometer hole and the second liquidometer hole longitudinal interval are arranged at the first half of tank body 200 sidewall, and the first liquidometer hole and the second liquidometer are longitudinally on same straight line.3rd liquidometer hole is identical with the second liquidometer with the first liquidometer hole with the 4th liquidometer hole set-up mode, is arranged at the lower part of tank body 200 sidewall.For convenience of operation, the first liquidometer hole, the second liquidometer hole are arranged with the 3rd liquidometer hole, the 4th liquidometer hole lateral alternate simultaneously.The top of tank body 200 also arranges pneumostome 224 and exhausr port 223.Pneumostome 224 place arranges breathing valve, and the second end of the air inlet pipe 124 of breathing valve is fixedly connected with pneumostome 224 by flange, thus is communicated with tank body 200 inside and breathing valve.For increasing air output, also can connect a breathing valve on exhausr port 223, connection mode is identical with the connection mode of pneumostome 224.
During charging, in hydrochloric acid tank, gas volume is subject to the extruding of poured into hydrochloric acid, is discharged by exhausr port 223 and pneumostome 224.The HCl gas of discharging enters the second cavity 122 by air inlet pipe 124, and with in the second cavity 122 in contact with hydrochloric acid solution surface.Most of acid mist is now also had to be neutralized in gas, thus can not be emptying.Because the second cavity 122 is totally-enclosed, gas can only from entering the first cavity 121 communicating pipe 112.During gas is passed into after entering the first cavity 121 and in hydrochloric acid solution, emptying from downtake pipe 111 without the gas overflowing solution surface of acid mist after neutralization.
During discharging, in hydrochloric acid tank, hydrochloric acid volume sharply reduces needs outside suck with balancing Atmospheric pressure.Absorption power conducts to the second cavity 122 from air inlet pipe 124.Due to communicating pipe 112 one end end in solution and the U-shaped end of communicating pipe 112 far above liquid level.Absorption power cannot make solution in the first cavity 121 pour in down a chimney into the second cavity 122.And the gas that can only compress in the second cavity 122, make air enter the second cavity 122 from second exhaust pipe 113, thus reach air pressure balance.
Adopt the breathing valve with said structure can be communicated with hydrochloric acid tank and air, be vented body can be prevented again unprocessed and directly emptying to environment.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
