3, CO
3 2-, OH amount and some other weak acid salt amounts summation.The basicity that contains in the nature raw water mainly is HCO
3 -Basicity.The method of basicity has IX, r-o-, electrodialysis, adds methods such as acid in the existing reduction water.IX is to utilize anionite-exchange resin and HCO
3Carry out permutoid reaction and be removed, or utilize Zeo-karb and the cationoid reaction of types such as hydrogen or ammonia generate hydrogen or ammonia again with HCO
3 -Generate gas at the boiler internal reaction and remove, the used resin of IX needs often regeneration, and not only facility investment is big, and operation is complicated, and running cost is high, and water consumption is about about 10%.R-o-, electrodialysis are the characteristics of utilizing film, under pressure or electric field action, remove the ion in anhydrating, and comprise HCO
3Thereby, reach the purpose of falling alkali, but r-o-, the IX of electrodialysis appts output investment ratio are higher, and easy scale formation, film obstruction, breed bacteria etc. influencing equipment steady running, water consumption is about about 30%.Adding acid system generally is to utilize volume pump etc. that acid solution is directly added water tank; Acid solution adds excessive easily, and is inhomogeneous when acid solution is mixed with, and boiler feed water system and boiler body are caused corrosion; Have a strong impact on boiler operatiopn; And whole water tank is all anticorrosion, drops into height, and the carbonic acid gas that adds the generation of acid back is difficult to remove.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the present invention will solve is: a kind of above-mentioned defective that solved is provided, can accomplishes to add sour accurate measurement, mix, and can effective elimination carbonic acid gas the buck treatment facility efficiently falls.
The technical solution adopted for the present invention to solve the technical problems is: the described buck treatment facility that efficiently falls is characterized in that: comprise water inlet pipe, acid solution adding apparatus, acid solution mixing device, gas and water separator and cylindrical shell, the cylindrical shell bottom is connected with water shoot;
The acid solution adding apparatus is made up of the sour case and first ejector, and first ejector is installed in the water inlet pipe, and sour case is connected through the acid solution inlet tube with first ejector;
The acid solution mixing device is made up of second ejector and air inlet tube, and second ejector is installed in the water inlet pipe, the place, rear position of first ejector, and an end of air inlet tube is connected to second ejector, and the other end is left a blank;
Gas and water separator comprises screen drum type water dispensing apparatus and gas exhausting device, and screen drum type water dispensing apparatus and gas exhausting device all are positioned at cylindrical shell, and wherein screen drum type water dispensing apparatus top is connected with the water side of water inlet pipe.
Described acid solution inlet tube is provided with regulated valve.Can control the acid solution add-on.
Described gas exhausting device is the needle-like tightness system, and the top is the needle-like trim, and the bottom is a sleeve pipe; The telescopic outer wall has the hole; Communicate with barrel, be provided with fly rod in the sleeve pipe, the top of fly rod is the acicular structure that adapts with the needle-like trim; The cylindrical shell top is stretched out on the top of gas exhausting device, and the bottom is positioned at 1/3 position of cylindrical shell height.When liquid level surpasses cylindrical shell height 1/3, the fly rod come-up, the gas exhausting device top seal makes cylinder internal pressure increase, and water in the cylindrical shell is got rid of.
The beneficial effect that the present invention had is: efficiently fall the buck treatment facility and can make that acid solution mixes, and add sour process be easy to control; Cooperatively interact through ejector spray and gas exhausting device and can realize removing the carbonic acid gas function, simple in structure, facility compact is easy to control; Can accomplish to add sour accurate measurement, mix, and can the effective elimination carbonic acid gas.
