Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of secondary pressurization and storage water supply in buildings and communities, and more specifically, to a device for automatically recycling and utilizing residual ozone. Background Art
[0002] When ozone is used to disinfect the secondary water supply in a community, the product generated after oxidation in water is oxygen; the ozone that fails to dissolve in water or overflows directly from water without oxidation is still ozone, which is called residual ozone or ozone tail gas.
[0003] The positive pressure feeding method is a quantitative feeding method that uses the outlet pressure of an ozone generator (usually 0.02 - 0.05 MPa) to directly lead it to the bottom of the water tank through a pipeline. This feeding method needs to overcome the gravitational influence of the water depth, so the residual pressure value of the ozone gas at the water inlet gradually decreases as the water depth increases; when the residual pressure value approaches zero, the positive pressure feeding method will fail (no longer able to emit gas). The residual pressure of the ozone gas entering the water in this feeding method is too low, resulting in low oxygen dissolution efficiency and a large amount of residual ozone overflowing from the water surface, which will overflow from the water tank through the ventilation pipe and the overflow pipe, causing harm to the air environment in the pump room; when the residual pressure of the ozone gas entering the water is too low, it may not be able to overcome the gravitational force of the water depth and cause the feeding system to fail.
[0004] The negative pressure feeding method is a method that pumps water from the water tank through a booster pump, and the pressurized water flow provided by its outlet pipe sucks the ozone gas generated by the ozone generator into the injector under negative pressure through the injector. The ozone gas is mixed with the pressurized water flow in the injector and then the mixture is led to the bottom of the water tank through a pipeline and released into the water through an aeration head or a perforated pipe. This feeding method can ignore the size of the outlet pressure of the ozone generator and is not restricted by the water depth. The higher the pressure value of the pressurized water flow, the higher the oxygen dissolution efficiency and the less the amount of residual ozone overflowing from the water tank; the defect is that an additional booster pump (power equipment) needs to be added, which generates additional electricity costs during use and increases the later maintenance cost; it is impossible to control the input amount according to the bacterial content in the water, and the electricity cost of the ozone generator is relatively high.
[0005] In summary, whether positive pressure feeding or negative pressure feeding is adopted, using the ozone disinfection method will inevitably produce more or less by-products - residual ozone (ozone tail gas).
[0006] Domestically, there is relatively mature application experience in ozone tail gas treatment only in large water plants, large sewage treatment plants, swimming pool circulating water treatment and other occasions. Generally, it is absorbed and treated by connecting activated carbon adsorption tanks and residual ozone decomposers in series in pressurized water flow. This treatment process has a high initial investment and a large amount of maintenance in the later stage. When treating the residual ozone in the regulating water tank, the treatment process must be greatly adjusted before it can be used directly. No matter how the treatment method that continues the direction of the process is modified, it is actually difficult to simplify it. From the perspective of scheme design, it cannot meet the requirements of being both economical and convenient for later maintenance and management. For this reason, there is an urgent need for a new treatment device that can quickly and effectively absorb residual ozone and can effectively reduce investment costs. Utility Model Content
[0007] In order to make up for the above shortcomings, the utility model provides an automatic recycling device for residual ozone, aiming to improve the domestic ozone tail gas treatment, which has only mature application experience in large water plants, large sewage treatment plants, swimming pool circulating water treatment and other occasions; generally, it is absorbed and treated by connecting an activated carbon adsorption tank and a residual ozone decomposer in series in a pressurized water flow. This treatment process has a high initial investment and a large amount of maintenance in the later stage; when treating the residual ozone in the regulating water tank, the treatment process must be greatly adjusted before it can be used directly. No matter how the treatment method that continues the process direction is modified, it is actually difficult to be simplified, and the design of the scheme cannot meet the problems of being both economical and convenient for later maintenance and management.
[0008] The utility model is achieved in this way:
[0009] The utility model provides an automatic recycling device for residual ozone, comprising a water tank, a blower, an air intake pipe, an exhaust pipe, an ozone concentration detector and a control box. The top of the water tank is provided with an air collecting chamber, which is communicated with the top space of the water tank. A fan room with independent space is provided at the lower side of the water tank. The blower and the control box are fixedly installed in the fan room. One end of the air intake pipe is connected to the air inlet of the blower, and the other end of the air intake pipe is communicated with the top of the air collecting chamber.
[0010] One end of the exhaust pipe is connected to the air outlet of the blower, and the other end of the exhaust pipe is connected to the porous tube at the bottom of the water tank. The control box is arranged on the partition between the fan chamber and the water tank. The fan chamber and the water tank share four partitions. An ozone concentration detector is arranged on the top of the air collecting chamber. The blower and the ozone concentration detector are both connected to the control box through a control cable. The ozone concentration detector is arranged to detect the residual ozone concentration overflowing in the water.
[0011] In one embodiment of the utility model, it also includes an inspection door, which is installed on the water tank and is arranged corresponding to the fan chamber.
[0012] In one embodiment of the utility model, the blower is a high-pressure blower that can overcome the gravity of the water depth and exhaust air at positive pressure at the bottom of the water tank.
[0013] In an embodiment of the utility model, the top inner bottom elevation of the exhaust pipe is higher than the highest water level.
[0014] In an embodiment of the utility model, an ozone generator is externally mounted on the water tank, and the control box is connected to the ozone generator via a control cable.
[0015] In an embodiment of the present utility model, the common partition between the fan chamber and the water tank is made of stainless steel.
[0016] The beneficial effects of the utility model are as follows: the residual ozone automatic recycling device obtained by the utility model through the above design, when in use, the ozone concentration detector detects the residual ozone concentration overflowed in the water in real time, and the detection signal is transmitted to the control box. When the ozone concentration in the air in the gas collecting chamber reaches the set upper limit threshold, the control box automatically turns on the blower, and the blower injects the ozone gas in the gas collecting chamber into the water through the air inlet pipe, the exhaust pipe and the porous pipe. The residual ozone is added in a pressurized quantitative manner to improve the gas dissolution efficiency. When the ozone concentration in the air in the gas collecting chamber drops to the set lower limit threshold, the control box automatically turns off the blower. When the blower is turned on, the ozone generator can be turned off through the control box linkage To reduce its power consumption, when the blower is turned off, the ozone generator can be turned on through the control box. The blower and its control box are built into the low-level fan room to reduce operating noise and facilitate operation and maintenance. The excellent heat transfer performance of the stainless steel partition is used to conduct heat and radiate heat with the low-temperature water storage on the other side, which can cool the fan room in real time and increase the service life of the control box and the blower. The automatic recovery and utilization device for residual ozone decomposes the residual ozone by re-putting it into water for secondary utilization, thereby eliminating the harm of residual ozone to the air environment of the pump room. At the same time, it also reduces the operating energy consumption of the ozone generator, and is economical and convenient for later maintenance and management. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment
[0025] Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a residual ozone automatic recovery and utilization device, including a water tank 110, a blower 150, an intake pipe 170, an exhaust pipe 180, an ozone concentration detector 130 and a control box 160. A gas collection chamber 120 is provided at the top of the water tank 110 and is communicated with the top space of the water tank 110. A fan chamber 140 with an independent space is provided at the lower side of the water tank 110. The blower 150 and the control box 160 are fixedly installed in the fan chamber 140. An inspection door 141 is further included. The inspection door 141 is installed on the water tank 110 and is arranged corresponding to the fan chamber 140. The arrangement of the inspection door 141 facilitates the maintenance of the blower 150 and the control box 160. One end of the intake pipe 170 is connected to the air inlet of the blower 150, and the other end of the intake pipe 170 is communicated with the top of the gas collection chamber 120;
[0026] One end of the exhaust pipe 180 is connected to the air outlet of the blower 150, and the other end of the exhaust pipe 180 is connected to the porous pipe 190 at the bottom of the water tank 110. The top inner bottom elevation of the exhaust pipe 180 is higher than the highest water level 111. The blower 150 and its control box 160 are built in the low-position blower room 140 to reduce operating noise and facilitate operation and maintenance.
[0027] An ozone concentration detector 130 is provided on the top of the gas collecting chamber 120. The blower 150 and the ozone concentration detector 130 are connected to the control box 160 through a control cable. The ozone concentration detector 130 is provided to detect the residual ozone concentration overflowing from the water. An ozone generator is externally installed in the water tank 110. The control box 160 is connected to the ozone generator through a control cable. The control box 160 can control the opening and closing of the ozone generator in a linked manner. The excellent heat transfer performance of the stainless steel partition is utilized to conduct heat and radiate heat with the low-temperature water storage in the water tank 110 on the other side, so that the fan room 140 can be cooled in real time, thereby improving the service life of the control box 160 and the blower 150.
[0028] Specifically, the working principle of the automatic recycling device for residual ozone is as follows: when in use, the ozone concentration detector 130 detects the residual ozone concentration overflowing in the water in real time, and the detection signal is transmitted to the control box 160. When the ozone concentration in the air of the gas collecting chamber 120 reaches the set upper limit threshold, the control box 160 automatically turns on the blower 150. The blower 150 injects the ozone in the gas collecting chamber 120 into the water through the air inlet pipe 170, the exhaust pipe 180 and the porous tube 190. The residual ozone is added in a pressurized quantitative manner to improve the gas dissolution efficiency. When the ozone concentration in the air of the gas collecting chamber 120 drops to the set lower limit threshold, the control box 160 automatically turns off the blower 150. When the blower 150 is turned on, the ozone generator can be turned off through the control box 160 to reduce its power consumption. When the blower 150 is on, the ozone generator can be started through the control box 160. The blower 150 and its control box 160 are built in the low-level fan room 140 to reduce operating noise and facilitate operation and maintenance. The fan room 140 and the water tank 110 share four partitions. The excellent heat transfer performance of the stainless steel partition is used to conduct heat and radiate heat with the low-temperature water in the water tank 110 on the other side, so as to cool the fan room 140 in real time and improve the service life of the control box 160 and the blower 150. The residual ozone automatic recycling device re-reuses the residual ozone into the water for secondary utilization to decompose it, thereby eliminating the harm of the residual ozone to the air environment of the pump room, and also reduces the operating energy consumption of the ozone generator, and is economical and convenient for later maintenance and management.
