Technical Field

[0001] This utility model relates to the technical field of chemical machinery and equipment, specifically to a purification and emission device for volatile gases from acidic and alkaline liquids. Background Technology

[0002] Currently, the acid and alkali storage tanks and other equipment in the water treatment workshop are located in one building. Because the acid and alkali liquids have a certain amount of volatility, and each of the existing storage tanks has a local discharge port on its top to ensure the daily evaporation of acid and alkali liquids and the emission of gases during unloading, the acid and alkali liquids, being hydrochloric acid and sodium hydroxide, have a strong corrosive effect on metals. Furthermore, the local discharge results in high concentrations of acid and alkali fumes within the workshop, which can corrode other equipment and facilities, and pose a significant safety hazard to workers within the workshop. Therefore, to ensure that the acid and alkali fumes emissions meet environmental protection requirements and to avoid corrosion of equipment and facilities, a device is needed that can fully absorb and purify the acid and alkali fumes before discharge, thus preventing corrosion damage to facilities and personnel poisoning. Summary of the Invention

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] like Figure 1 As shown, an acid-base liquid volatile gas purification and emission device includes an acid-base tank 1, an emission port 2 located at the top of the acid-base tank 1, a cylindrical container 9, an acid-base mist adsorbent 8 disposed in the container 9, a filling port 6 and a discharge port 10 located at the top and bottom of the container 9 for filling and discharging the acid-base mist adsorbent 8, respectively, and an exhaust pipe 5 located at the top of the container 9. An air inlet pipe 3 is provided between the emission port 2 and the side wall of the container 9. The acid-base mist discharged from the acid-base tank 1 through the emission port 2 is transported to the container 9 through the air inlet pipe 3. After the acid-base mist adsorbent 8 absorbs the toxic and corrosive gas, the gas is discharged through the exhaust pipe 5 at the top.

[0020] In practical use, container 9 is connected to the local discharge port 2 on acid-base tank 1 via air inlet pipe 3. Acid-base mist adsorbent 8 in container 9 is injected through the top filling port 6. When the volatile acid-base mist formed by the acid-base liquid is transported into container 9 through air inlet pipe 3, the toxic and harmful substances in the acid-base mist are absorbed by the acid-base mist adsorbent 8, and the non-toxic and harmless gas is discharged to the outside through the top exhaust pipe 5, thereby achieving the purification treatment of volatile gas from acid-base liquid. When purifying volatile gas from acid-base liquid through container 9, the exhaust gas is sampled and analyzed periodically at the top exhaust pipe 5. If the analysis results are not up to standard, the acid-base mist adsorbent 8 is replaced. The acid-base mist adsorbent 8 is discharged through the bottom discharge port 10 for harmless treatment; then new adsorbent is loaded through the top filling port 6. By absorbing and releasing acid and alkali mist, the problem of corrosion and damage to equipment and facilities caused by the direct discharge of corrosive and toxic mist generated by the volatilization of acid and alkali liquids can be effectively avoided. It can also avoid the risk of poisoning to workers caused by the mist being released into the air. The modification cost is low and there is no maintenance cost.

[0021] A further improvement is that a filter cover 7 is provided inside the top of the container 9, and the purified gas in the container 9 is filtered through the filter cover 7 and then enters the exhaust pipe 5 for external discharge.

[0022] The filter cover 7 effectively filters the acid and alkali mist adsorbent 8 and its accompanying powder, preventing particulate acid and alkali mist adsorbent 8 from being directly discharged outward from the exhaust pipe 5 along with the gas. The filter cover 7 uses a metal filter mesh, preferably 316L stainless steel wire mesh, which has a longer service life and better corrosion resistance.

[0023] A further improvement is that a pressure measuring instrument 4 is provided between the container 9 and the air inlet pipeline 3.

[0024] The pressure measuring instrument 4 can reflect the pressure changes inside container 9 in a timely manner. When the pressure rises, it is considered that the adsorbent bed is severely powdered, and the adsorbent is then replaced.

[0025] A further improvement is made by rolling the container 9 from a 5mm thick stainless steel sheet. The air intake pipe 3 is composed of The structure is made of stainless steel tubing; the exhaust pipe 5 is composed of... The structure is made of stainless steel tubing.

[0026] It is small in size, easy to install, highly corrosion resistant, and very sturdy.

[0027] A further improvement is made in that the acid-base mist adsorbent 8 filled in the container 9 is positioned 20cm above the top of the container 9. This pre-reserved space at the top allows for efficient and rapid emission of filtered gas. The acid-base mist adsorbent 8 uses SDG adsorbent, resulting in better purification.

[0028] A further improvement is made in that the filter cover 7 is made of multiple layers of stacked metal mesh.

[0029] Since the SDG adsorbent will float up after being pulverized and enter the filter hood 7, in order to better filter the SDG adsorbent, the filter hood 7 is made of at least two stainless steel tube metal filter screens stacked and installed in the container 9. This makes the dust filtration more effective. When blockage occurs, it can also be cleaned by reverse inflation, which is simple and convenient to operate.

[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
