The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Please combine referring to Fig. 1 and Fig. 2, the invention provides and be installed on the hydrochloric acid tank exhausr port or/and the breathing valve of pneumostome.Breathing valve is circular.Breathing valve comprises that inside has the valve body 120 of cavity, the body cap 110 that cooperates with valve body 120 and is sandwiched in valve body 120 and the tightening seal washer 130 of 110 of body caps.Raised line 123 is set in the valve body 120, the cavity of valve body 120 is divided into first cavity 121 and second cavity 122.Use solution with hydrochloric acid in all holding in first cavity 121 and second cavity 122, like sodium hydroxide solution, water etc.Holding solution in preferred first cavity 121 is water, and holding solution in second cavity 122 is alkaline solution.Can practice thrift the consumption of alkali lye, can make the solution in the cavity 121 of winning become hydrochloric acid solution again.On body cap 110 and first cavity, the 121 cooresponding zones downtake pipe 111 that is communicated with first cavity 121 is installed.Downtake pipe 111 can stretch in first cavity 121 but in the liquid that do not submerge, can discharge from downtake pipe 111 so that get into first cavity, 121 gases.First cavity 121 and second cavity 122 were communicated with through communicating pipe 112, and communicating pipe 112 is installed on the body cap 110.Communicating pipe 112 can be communicating pipe, also can be communicated with the pipeline of first cavity 121 and second cavity 122 for any other.First end of communicating pipe communicating pipe 112 submerges under the liquid level of solution in first cavity 121, so as with the gas of second cavity 122 import in first cavity 121 in hydrochloric acid with in the solution, fully react with it, acid mist is neutralized.Second end of communicating pipe 112 then stretches into second cavity 122 but in the solution in second cavity 122 that do not submerge, so that the gases in first cavity 121 are exported in second cavity 122.Body cap 110 and valve body 120 are connected through screw retention, and tightening seal washer 130 is clamped to realize sealing.
The air inlet pipe 124 with the hydrochloric acid tank internal communication is installed in the bottom of second cavity 122 of valve body 120.Air inlet pipe 124 is a straight tube; First end of air inlet pipe 124 stretches in second cavity 122; And during this first port is higher than with hydrochloric acid with the liquid level of solution, in case in pour in down a chimney from air inlet pipe 124 with solution with hydrochloric acid and to get in the hydrochloric acid tank, in influence its quality with the interior hydrochloric acid of hydrochloric acid tank.Second end of air inlet pipe 124 is fixed on the exhausr port or breathing valve of hydrochloric acid tank through flange, so that the gases such as acid mist in the hydrochloric acid tank are got in second cavity 122 through air inlet pipe 124.First end of air inlet pipe 124 and second side of communicating pipe 112 are the setting of staggering.Be set the contact time that can increase neutralization solution in the acid mist and second chamber 122 like this, prevent directly to get into communicating pipe 112 from the acid mist that air inlet pipe 124 gets into second cavity 122.On the body cap 110 of corresponding second cavity 122, the submerge second exhaust pipe 113 of solution in second cavity 122 of first end has been installed also.Second end of second exhaust pipe 113 stretches out valve body 120 and atmosphere.First end of second exhaust pipe 113 solution that submerges can prevent to get into from air inlet pipe 124 the direct emptying of acid mist of second chamber 122.
Please refer to Fig. 3, particularly, in this embodiment, tightening seal washer 130 comprises the vertical bar of annulus and symmetry separation annulus.Tightening seal washer 130 cooperates with valve body 120 peripheries and raised line 123.Tightening seal washer 130 can make the cavity 121 of winning can only pass through communicating pipes 112 connection with second cavity 122 first cavity 121 and second cavity, 122 seal in the valve body 120.
Please combine Fig. 4 and Fig. 5, hydrochloric acid tank comprises tank body 200, a plurality of discharging opening 210 that is arranged at tank body 200 side walls, a plurality of inlet point 221 that is symmetricly set in tank body 200 tops, be arranged at center, tank body 200 tops first manhole 231, be arranged at second manhole 232 and a plurality of liquidometer hole 241 that is arranged at tank body 200 sidewalls of tank body 200 side walls.
4 liquidometer holes 241 preferably are set, comprise the first liquidometer hole, the second liquidometer hole, the 3rd liquidometer hole and the 4th liquidometer hole.The first liquidometer hole and the second liquidometer hole longitudinal interval are arranged at the first half of tank body 200 sidewalls, and the first liquidometer hole and second liquidometer vertically are on the same straight line.The 3rd liquidometer hole is identical with 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 sidewalls.Be handled easily, the first liquidometer hole, the second liquidometer hole are provided with the 3rd liquidometer hole, the 4th liquidometer hole lateral alternate simultaneously.The top of tank body 200 also is provided with pneumostome 224 and exhausr port 223.Pneumostome 224 places are provided with breathing valve, and second end of the air inlet pipe 124 of breathing valve is captiveed joint with pneumostome 224 through flange, thereby are communicated with tank body 200 inside and breathing valve.For increasing air output, also can on exhausr port 223, connect a breathing valve, connection mode is identical with the connection mode of pneumostome 224.
During charging, gas volume receives the institute's hydrochloric acid that pours into extruding in the hydrochloric acid tank, discharges through exhausr port 223 and pneumostome 224.The hydrochloric acid gas of discharging gets into second cavity 122 through air inlet pipe 124, and with second cavity 122 in contact with solution surface with hydrochloric acid.Also have this moment most of acid mist not obtain neutralization in the gas, thereby can not emptying.Because second cavity 122 is totally-enclosed, gas can only get into first cavity 121 from communicating pipe 112.During gas gets into and is passed into behind first cavity 121 with hydrochloric acid with in the solution, neutralization afterwards the gas spillage solution surface of no acid mist from downtake pipe 111 emptyings.
During discharging, the hydrochloric acid volume sharply reduces in the hydrochloric acid tank needs outside suck to press with balancing Atmospheric.Absorption power conducts to second cavity 122 from air inlet pipe 124.Since the end end of communicating pipe 112 in solution and the U type end of communicating pipe 112 far above liquid level.Absorption power can't make first cavity, 121 interior solution pour in down a chimney into second cavity 122.And can only compress the gas in second cavity 122, make air get into second cavity 122, thereby reach air pressure balance from second exhaust pipe 113.
The breathing valve that employing has said structure can be communicated with hydrochloric acid tank and atmosphere, can prevent that again institute's exhaust body is unprocessed and direct emptying pollutes environment.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
