Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a special steam-water separation and adsorption integrated tank for ozone tail gas. Background Art

[0002] The ozone generator is used in conjunction with the ozone contact tank to oxidize and degrade difficult-to-degrade substances such as COD in the water. Currently, many water plants involved in printing and dyeing industrial water are using ozone generators in conjunction with MBR membranes as the main process for sewage treatment. The ozone tail gas that cannot be consumed in the ozone contact tank enters the tail gas destruction device for ozone decomposition, mainly using catalytic fillers + heating electrodes for decomposition treatment.

[0003] While the ozone generator is treating water through the ozone contact tank, some parts of the site do not have gas-water separation storage and equipment. The ozone tail destruction system on site with separation equipment cannot completely eliminate the odor on site. Due to the strong oxidizing properties of ozone, long-term and large-scale intake will cause damage to the human respiratory tract, and will also be accompanied by symptoms such as vomiting, greatly increasing the risk of environmental inspections.

[0004] Since printing and dyeing enterprises have their own treatment stations, the COD in the water discharged after treatment is basically non-degradable or difficult to degrade. The ozone oxidizing ability is insufficient and has certain limitations, which will lead to unstable ozone dosage on site and cause the following problems:

[0005] 1. A large number of bubbles will be generated, which will enter the packing device as they are sucked into the destructive fan, causing partial failure of the tail breaker system. The ozone smell on site is extremely strong, and normal inspection and maintenance operations cannot be carried out. At the same time, the environmental protection department will not allow large-scale leakage or strong odor.

[0006] 2. The existing tail gas destruction system discharges a large amount of ozone before it has time to react in the contact tank, resulting in a large amount of residual gas, which exceeds the processing capacity of the tail gas destruction system. Utility Model Content

[0021] like Figure 1 As shown, the utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, including a tank body 1, an air outlet is provided on the top of the tank body 1, an air inlet is provided on one side of the tank body 1, and a vent is provided on the other side of the tank body 1. A packing layer 8 is provided at the upper end of the interior of the tank body 1, and an observation and maintenance manhole 5 is also provided on the tank body 1, and the observation and maintenance manhole 5 is provided below the packing layer 8.

[0022] The ozone tail gas dedicated steam-water separation and adsorption integrated tank further comprises a screen 20 , which is installed inside the tank body 1 near the top of the tank body 1 , and the space between the screen 20 and the top of the tank body 1 is a packing layer 8 .

[0023] The ozone tail gas dedicated steam-water separation and adsorption integrated tank further comprises a screen fixing device 21 , which is mounted on the inner side wall of the tank body 1 , and the screen 20 is mounted on the screen fixing device 21 .

[0024] The distance between the screen 20 and the top inner wall of the tank body 1 is 45CM.

[0025] The ozone tail gas dedicated steam-water separation adsorption integrated tank also includes an air inlet pipe 2, an air outlet pipe 3, and a vent pipe 4. The air inlet pipe 2 is installed on the air inlet, the air outlet pipe 3 is installed on the air outlet, and the vent pipe 4 is installed on the vent.

[0026] The ozone tail gas dedicated steam-water separation and adsorption integrated tank further comprises a valve 6 , one side of the vent pipe 4 is mounted on the tank body 1 , and the other side of the vent pipe 4 is mounted with a valve 6 .

[0027] This ozone exhaust gas steam-water separation and adsorption integrated tank also includes footings 7, mounted on the bottom of the tank body 1. These footings 7 are three-claw type. The mounting base (footings 7) utilizes a three-claw support structure. The height of the mounting base is based on the standard tank installation height and can be adjusted on-site based on the environment. In this embodiment, the height of footings 7 is 15 cm.

[0028] The material of the tank body 1 is 316L stainless steel.

[0029] The vent pipe 4 is made of 316L stainless steel, and a ball valve with good sealing performance is preferably used as the valve 6. The vent pipe is 10 cm away from the bottom of the tank 1. The height of 10 cm is left for the convenience of maintenance work.

[0030] The inlet is 20 cm away from the bottom of the tank 1, which ensures a certain amount of liquid storage and prevents the pipeline from being blocked. The DN150 caliber is matched with the ozone pipeline used on site, and can be adjusted according to the actual situation on site.

[0031] An observation and maintenance manhole 5 is designed in the middle of the tank 1 to facilitate observation of the liquid level in the tank 1 and cleaning of the tank bottom accumulated impurities.

[0032] The gas outlet is arranged at the top of the tank 1, which can effectively prevent fillers, impurities and the like from entering the tail breaking system. After the initial adsorption, it is re-entered into the tail breaking system for secondary breaking.

[0033] The screen 20 is a device for placing normal temperature high efficiency adsorption filler. The bottom is provided with a net support for preventing the screen from falling off and strengthening the bearing capacity of the screen 20. The screen 20 is made of 3 mm steel plate, and the screen hole diameter is 6 mm. A layer of pebbles is laid on the screen 20, and then the normal temperature high efficiency adsorption filler is fully laid on the pebbles. The size of the pebbles is selected according to the aperture of the screen, mainly to prevent the filler from falling off. Because the screen hole is too small, it will cause blockage, and the gas cannot be lifted, which cannot effectively adsorb. Laying pebbles on the screen 20 will not block the screen, and can also prevent part of the filler from falling off from the screen hole. The filling amount of the filler is added according to the actual ozone output on site. Generally, the filler is added at about 1:7-1:8, which has good effect. The screen hole can be determined according to the actual situation, mainly according to the excess ozone of the on-site equipment. The main ozone has limited oxidizing property and is targeted, and cannot be oxidized and decomposed indiscriminately. Therefore, the air volume adjustment is also different. The design of selecting columnar 3MM filler can meet 80% of the environmental application, as follows:

[0034] Specification Specific surface area Bulk density strength Operating temperature illustrate Columnar 1.1mm BET≥190 0.68(±0.05) >45N 10-400℃ Suitable for small air volume and high concentration ozone decomposition Columnar 3mm BET≥190 0.68(±0.05) >45N 10-400℃ Highly efficient ozone decomposition in most situations 5mm cylindrical BET≥190 0.68(±0.05) >45N 10-400℃ Suitable for decomposing ozone tail gas with large air volume

[0035] The utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, the main purpose of which is to separate the large amount of foam generated in the ozone contact tank after ozone is introduced or added, and to install a layer of high-efficiency adsorption filler at room temperature for initial adsorption. After adsorption, the tail gas is broken through the existing tail breaking system, which greatly protects the use of the existing destruction system and the effectiveness of the filler, thereby directly reducing maintenance and replacement costs. From a safety perspective, the utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, which greatly reduces the operational risks of personnel inspection and maintenance. From an environmental protection perspective, the utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, which greatly reduces environmental risks.

[0036] The utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, which solves the problem of conventional steam-water separation and can effectively perform initial adsorption at the same time, and is effective in reducing the ozone odor and the concentration of unabsorbed ozone gas on site. In previous projects, a large number of projects had no way to deal with the ozone tail destruction system. The utility model discloses a special steam-water separation and adsorption integrated tank for ozone tail gas, which is a device that targets the ozone tail destruction system, finds the root cause and hits the key points to completely eradicate it.

[0037] The utility model discloses a steam-water separation and adsorption integrated tank for ozone tail gas, which also has the following advantages: 1. The steam-water separation is performed simultaneously with the initial adsorption of the ozone tail gas; 2. The adsorption can be performed at room temperature without heating; 3. The steam-water separation effect is significant and will not enter the subsequent destruction system and cause damage to the equipment.

[0038] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
