Description
Technical Field
The utility model belongs to the technical field of the system acid equipment, specifically a system acid absorption tower circulating slot device of adding water.
Background
In the prior art, a circulating tank of an absorption tower of a sulfuric acid production line generally uses an acid mixer to supplement water or directly supplements water through a stainless steel pipe; in the actual production process, the acid mixer or the stainless steel pipe is used for supplementing water or directly supplementing water through the stainless steel pipe, the acid mixer or the stainless steel pipe is very easy to corrode and needs to be replaced frequently, and not only the absorption circulation system is corroded seriously, but also the subsequent equipment and pipelines are corroded seriously, so that the service lives of the equipment and the accessory facilities are shortened, and great economic loss is caused. In addition, the acid mixer water replenishing or the stainless steel pipe water replenishing directly has the problem that the concentration of the circulating acid is unstable and uncontrollable.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's not enough, provide an acid making absorption tower circulating groove device of adding water, its is corrosion-resistant, long service life, the concentration of circulating acid is stable, balanced, controllable.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a device of adding water in acid making absorption tower circulating slot, includes the absorption tower circulating slot, and absorption tower circulating slot side bottom is equipped with acid return mouth, is equipped with the filler on the absorption tower circulating slot, its characterized in that: a tetrafluoro water adding pipe vertically extending into the absorption tower circulating groove is arranged on the water adding port, the lower end of the tetrafluoro water adding pipe extends to an inlet of the acid return port, the lower end of the tetrafluoro water adding pipe is sealed, and a plurality of water outlet holes are formed in the pipe wall of the lower end of the tetrafluoro water adding pipe; the upper end of the tetrafluoro water adding pipe is connected with a vertical exhaust pipe made of glass fiber reinforced plastic, and the lower end of the exhaust pipe is communicated with a water adding pool made of glass fiber reinforced plastic through a U-shaped pipe made of glass fiber reinforced plastic.
Furthermore, the inner diameter of the tetrafluoro water adding pipe is phi 40-60 mm.
Furthermore, the inner diameter of the water outlet hole is phi 8-12 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses use the tetrafluoro filler pipe, it can be at-60- +260 ℃ internal normal use, has reliable good corrosion resistance, and it is obvious to compare the advantage with the direct moisturizing of prior art's stainless steel mixed acid ware and stainless steel pipe. The stainless steel acid mixer is used for replenishing water, so that the dilute acid and heat generated in the stainless steel acid mixer can accelerate the corrosion speed of the acid mixer, influence the service life of the acid mixer and cause corrosion to a circulating system and subsequent facilities and equipment; the stainless steel pipe is used for directly supplementing water, steam can be directly generated on the liquid level of the circulating tank to corrode the tank body of the circulating tank, the dilute acid generated on the liquid level floats on the concentrated acid and is layered in the circulating tank, so that a lot of troubles are brought to the operation, the uniformity and stability of the acid absorbed in the circulating tank cannot be ensured, important equipment and facilities such as a circulating pump, an acid feeding pipe, an acid distributor, a foam catcher, an acid return pipe, an anode protector and the like can be corroded at first, the subsequent corrosion of a flue gas pipeline and a heat exchanger can be directly caused, and the service life of the equipment and facilities can be seriously influenced; the utility model overcomes above-mentioned prior art's shortcoming.
(2) The lower end of the tetrafluoro water adding pipe vertically extends into a position corresponding to an acid return port at the bottom of the circulating tank of the absorption tower, and a plurality of water outlet holes are formed in the pipe wall of the lower end of the tetrafluoro water adding pipe; the water that flows in from the apopore can fully contact, mix with the extremely strong absorption tower backward flow acid of mobility, and the dilute acid that produces around water filler lower extreme apopore 6 can promote rapidly to be concentrated acid at this in-process to can guarantee the even stability of the absorption tower circulation tank body 1 internal circulation acid concentration after adjusting and not laminate. The heat generated around the lower end of the tetrafluoro water adding pipe can be rapidly dispersed and cooled due to violent stirring, and water vapor and dilute acid are avoided.
(3) The upper end of the tetrafluoro water adding pipe is connected with a vertical exhaust pipe, and the lower end of the exhaust pipe is communicated with a water adding pool through a U-shaped pipe. Because the specific gravity of the primary water is lower than that of the circulating acid, bubbles generated by heat generated by instant contact of the water and the concentrated acid can be discharged through the exhaust pipe, the U-shaped pipe has a water sealing effect, and the water adding pool can not splash.
(4) The utility model discloses the device uses the back, and the concentration of dry, absorptive circulation acid is all very stable, balanced, controllable, and each item technological index is all very normal, and device itself is also very corrosion-resistant, and circulation system and follow-up equipment facility do not have corrosion phenomenon again.
