Description
Technical Field
The utility model relates to a flue gas desulfurization handles the field, more specifically relates to an ammonia process desulfurization absorption tower.
Background
The flue gas discharged from a waste water and waste liquid incinerator of a rubber chemical plant contains more sulfur dioxide. Ammonia desulfurization is generally used, i.e. ammonia-containing water is brought into contact with flue gas by spraying to absorb sulfur dioxide in the flue gas and finally to generate ammonium sulfite.
The reaction process can be basically expressed as: the sulfur dioxide in the flue gas is firstly absorbed by water to generate hydrogen ions, bisulfite ions and sulfite ions, and then the hydrogen ions and hydroxide radicals generated by dissolving ammonia gas in water are combined to generate water molecules. Because the hydrogen ions and the hydroxyl ions are continuously consumed, the reaction of dissolving the sulfur dioxide in the water and dissolving the ammonia in the water is continuously carried out, and the sulfur dioxide in the flue gas is absorbed and purified.
In addition, ammonium ions, bisulfite ions and sulfite ions in the system are increased, and then the sulfite ions and the bisulfite ions are oxidized to generate sulfate radicals, and finally ammonium sulfate is generated and recovered in the concentration stage. The absorption reaction formula is as follows:
2SO3 2-+O2＝2SO4 2- (6)
among the above reactions, (7) is one of the final reactions. The saturation concentration of the ammonium sulfate solution has a certain relationship with the solids content of the slurry. Typically, slurries containing 10% to 15% solids can also be recycled for sulfur dioxide absorption. When the content of solid particles in the slurry is too high, the solid particles are recycled. While the slurry contains solid particles when the ammonia desulphurization absorption tower operates, the common spraying method is easy to block the spray head,

The utility model provides an ammonia process desulfurization absorption tower can include at least one spray branch 6, and spray branch 6 sets up in the inner chamber of tower body 1, and its feed liquor end communicates with the outside of tower body 1. In the exemplary embodiment, the inlet ends of the spray branch pipes 6 communicate with the outside of the tower 1 through the spray main pipe 5.

And the tower body 1 is provided with a connecting structure corresponding to the position of the main spraying pipe 5.
The spray branch pipes 6 are temperature-resistant glass fiber reinforced plastic branch pipes, namely the spray branch pipes 6 are made of temperature-resistant glass fiber reinforced plastic.

The embodiment of the utility model provides an ammonia process desulfurization absorption tower, the gas inlet of tower body 1 sets up in the below of pottery vortex nozzle 7, and the exhanst gas outlet of tower body 1 sets up the top at pottery vortex nozzle 7. When the ammonia desulphurization absorption tower is used, sulfur-containing high-temperature flue gas is transmitted from the lower part of the tower body 1 to the upper part. Slurry containing ammonium sulfite enters the ceramic vortex nozzle from the outside of the tower body 1 through the spray branch pipe 6 and is further conveyed into the inner cavity of the tower body 1. Wherein the slurry can be transported from the outside of the tower 1 to the spray branch pipes 6 via the main spray pipe 5. The slurry sprayed from the ceramic swirl nozzles 7 mixes with the flue gas and can absorb sulfur-containing substances such as sulfur dioxide in the flue gas and some other substances in the flue gas. The slurry after absorbing the flue gas can fall to the bottom of the tower body 1.
The embodiment of the utility model provides an ammonia process desulfurization absorption tower is used for the thick liquid that sprays through setting up spray branch pipe in order to supply to ceramic vortex nozzle, can guarantee to spray the thick liquid in to the tower body unobstructed, and is good to the purifying effect of flue gas. The ammonia desulphurization absorption tower can be used independently, and can also be used together with other equipment. Other pipelines or devices can be arranged in the tower body 1 of the ammonia desulphurization absorption tower to comprehensively treat the flue gas.
Referring to fig. 1 and 2, in an exemplary embodiment, the ammonia desulfurization absorption tower further includes a first desulfurization liquid connection port 2; the outer wall surface of the main spraying pipe 5 is hermetically connected with the tower body 1, and the main spraying pipe 5 is communicated with the outside of the tower body through a first desulfurization liquid connecting pipe orifice 2. Specifically, the first desulfurization liquid connection pipe orifice 2 is used for connecting with an external device or a pipeline, such as a liquid outlet pipe of a liquid pump.
The tower body 1 is further provided with a fixing flange 4, for example. The inner hole of the fixed flange 4 penetrates through the inside and the outside of the tower body 1 and is suitable for penetrating the main spraying pipe 5. One end of the first desulfurization liquid connecting pipe orifice 2 is fixedly connected with the spraying main pipe 5, and the peripheries of the two ends of the first desulfurization liquid connecting pipe orifice 2 are respectively provided with a flange plate. On the first desulfurization liquid connecting pipe orifice 2, a flange plate at one end connected with the spraying main pipe 5 is used for being hermetically connected with the fixed flange 4, and a flange plate at the other end is used for being hermetically connected with external equipment. The arrangement of the fixing flange 4 also helps to reduce the tendency that heat in the tower body 1 is transferred to the outside of the tower body 1 through the main spraying pipe 5.
In an exemplary embodiment, the material of the main spray pipe 5 is temperature-resistant glass fiber reinforced plastic, and the material of the first desulfurization liquid joint pipe orifice 2 is temperature-resistant glass fiber reinforced plastic. The spraying main pipe 5 made of the temperature-resistant glass fiber reinforced plastic material can better bear high-temperature flue gas in the tower body 1, and resist scouring during slurry conveying and resist corrosion of solutes such as ammonium sulfite and the like. And is easily connected with the shower branch pipe 6 for flexibly arranging the ceramic swirl nozzles 7. The first desulfurization liquid connection pipe orifice 2 made of temperature-resistant glass fiber reinforced plastic material can be integrally manufactured with the spraying main pipe 5.

In practice, the tower body 1 may be manufactured first, and then the reinforcing rods are fixedly connected to the tower body 1. A portion of the reinforcing bar is molded in when the shower main pipe 5 is manufactured. The material of stiffener can be temperature resistant steel, therefore the external diameter of stiffener can be thinner, and the pipe diameter that sprays main pipe 5 is thicker, therefore the stiffener can hardly influence the thick liquid transport that sprays in the main pipe 5.
Illustratively, the liquid outlet end of the spray branch pipe 6 is lower than the reinforcing rod, or the liquid outlet necking 74 of the ceramic vortex nozzle 7 is lower than the reinforcing rod. This prevents the reinforcing bar from interfering with the ejection of slurry. Of course, when a plurality of layers of ceramic swirl nozzles are provided, the ceramic swirl nozzles 7 at each layer position are lower than the reinforcing rods of the same layer. The ceramic swirl nozzles 7 of the different layers are far from the reinforcing rod, and thus the ejection of the slurry is not considered to be affected.

Illustratively, a discharge pump is connected to the bottom of the tower 1. Due to the high temperature of the flue gas to be treated, the water content in the ammonium sulfite slurry sprayed by the ceramic vortex nozzle 7 is evaporated, and the concentration of the ammonium sulfite slurry is higher and higher along with the recycling of the slurry. And the slurry continuously absorbs sulfur dioxide in the flue gas to further continuously generate ammonium sulfate. When the solid content of the slurry reaches 15%, for example, the slurry in the liquid pool can be discharged to an ammonium sulfate post-treatment system by a discharge pump.
