Description

Technical Field

[0001] This utility model belongs to the field of odor control technology, specifically involving a biological liquid blowing deodorization system based on the U-tube principle. It is suitable for the efficient removal of NH3 and H2S in large spaces such as poultry and livestock farms. It achieves low energy consumption and high coverage deodorization effect through U-tube siphon liquid supply technology, and is suitable for large space scenarios such as pigsties and cattle sheds. Background Technology

[0002] With the rapid development of my country's livestock and poultry farming industry, large-scale farming has become the mainstream. However, the problem of odor pollution has become increasingly prominent. Among common farmed livestock and poultry, cattle and pigs produce relatively high levels of odor. Cattle produce methane during digestion, while pig excrement contains large amounts of NH3 and H2S. The accumulation of these gases in farms can seriously affect the normal growth of cattle and pigs, as well as impact the atmospheric environment and endanger the health of surrounding residents.

[0003] Currently, high-pressure spraying is commonly used in livestock farms to reduce the concentration of malodorous gases such as NH3 and H2S. However, to achieve good atomization and spray micron-sized droplets, a consistently high pressure is required, significantly increasing equipment energy consumption and resulting in high long-term operating costs. Furthermore, high pressure also increases spray flow rate; further reducing the nozzle diameter easily leads to nozzle blockage. Under the same conditions, the equipment is expensive and difficult to install. In addition, the applicant's earlier application CN202311629051.6 discloses a bubble-blowing deodorization system based on bubble breaking. This system's deodorizing liquid supply unit relies on an electric pump for continuous delivery of the deodorizing liquid, resulting in high energy consumption and limiting its practical application in large-scale livestock farm deodorization scenarios.

[0026] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0027] Example 1

[0028] This embodiment of the biological liquid bubble deodorization system based on the U-tube principle includes a deodorization chamber 1, a bubble generating device component unit 2, a deodorizing liquid supply component unit 3, and an ammonia and hydrogen sulfide gas detector 4. The deodorizing liquid supply component unit 3 includes a high-level supply tank 302, a high-level supply tank support 301, a water valve 304, and a U-shaped flexible hose 303.

[0029] The high-level liquid supply tank is supported and installed on the outer wall of the farm by the high-level liquid supply tank bracket 301. The liquid level of the high-level liquid supply tank is not less than the upper limit of the liquid level in the bubble generating device component unit. Microbial deodorizing liquid or plant deodorizing liquid and other deodorizing liquids are stored in the high-level liquid supply tank.

[0030] One end of the elevated liquid supply tank is connected to the inlet of the bubble generator in the bubble generator assembly unit via a U-shaped flexible hose 303. A switch valve is installed on the U-shaped flexible hose to control the connection or closure of the U-shaped flexible hose.

[0031] In this embodiment, the U-shaped hose is made of PVC hose and delivers the deodorizing liquid to the bubble generating device. The liquid level difference is used to achieve siphon supply, which does not require external power.

[0032] Example 2

[0033] In this embodiment, the bubble generator (a modified commercial bubble machine) is installed on the inner wall of the pigsty, with a horizontal spacing of 3m and staggered arrangement. The bubble outlet faces the central area of ​​the pigsty, and the single-machine blowing rate is ≥200 bubbles / min, generating bubbles with a diameter of 3.5-4.5cm. During the floating process, the bubbles naturally break due to the weakening of surface tension or airflow disturbance, forming micron-sized droplets of 20-50μm, which significantly enhances the gas-liquid interface reaction.

[0034] Example 3

[0035] The microbial deodorizing liquid selected in this invention is based on Yijiayi brand microbial deodorizer, compounded with CAB-35 amphoteric surfactant and tap water, and rich in functional bacteria such as ammonia-oxidizing bacteria (AOB), nitrite-oxidizing bacteria (NOB), and sulfur-oxidizing bacteria (SOB). These microorganisms decompose malodorous gases such as NH3 and H2S as nutrients through metabolic activities such as oxidation-reduction, nitrification, and denitrification. In the liquid phase, AOB and NOB gradually convert NH3 into nitrates, and SOB oxidizes H2S into sulfate ions. In the gas phase, the micron-sized droplets formed by the breaking of bubbles increase the gas-liquid contact area, enhance the mass transfer reaction, and ultimately generate CO2, H2O, and SO4. 2- NO3 - Harmless byproducts. The floating and breaking characteristics of the bubble-blowing process ensure uniform dispersion of the deodorizing liquid, achieving efficient removal of NH3 and H2S in farms without the need for high-pressure equipment. It combines environmental friendliness and low energy consumption, making it suitable for large spaces such as pigsties and cattle sheds.

[0036] Example 4

[0037] The deodorizing liquid supply in this invention utilizes a U-shaped flexible hose connecting a high-level supply tank and a bubble generator located on the inner wall of the deodorizing chamber. Due to the level difference between the high-level supply tank and the bubble generator, the deodorizing liquid automatically flows from the high-level supply tank to the bubble generator through the U-shaped hose under the siphon effect, eliminating the need for additional pumping power equipment and significantly reducing energy consumption. Simultaneously, a manual on / off water valve is installed on the U-shaped hose, and upper and lower level limits are set within the bubble generator. The user can manually control and flexibly adjust the water level, and by observing whether the liquid level in the bubble generator is close to the upper limit, the supply volume can be controlled. This supply method is not only simple in structure but also stable and reliable, effectively avoiding supply problems caused by pump equipment failure.

[0038] Example 5

[0039] This embodiment uses a U-tube principle for liquid supply and bubble deodorization (see [reference]). Figure 1 The system includes a bubble generating device component unit 2 and a deodorizing liquid supply component unit 3. Multiple bubble generating device component units 2 are evenly distributed in the upper part of the deodorizing chamber 1. The bubble generating device component unit 2 uses the prepared bubble-blowing deodorizing liquid as raw material to blow out a large number of bubbles. These bubbles break into numerous tiny droplets, which react with odor molecules dispersed in the air, thereby removing odors such as NH3 and H2S. The deodorizing liquid supply component unit 3 is connected to the bubble generating device component unit 2 based on the U-tube principle, and the liquid levels of both are automatically leveled, providing deodorizing liquid to the bubble generating device component unit 2.

[0040] The liquid level in the elevated supply tank is not less than the upper limit of the liquid level in the bubble generator. In this embodiment, the liquid level in the elevated supply tank is 2.5m.

[0041] The high-level liquid supply tank bracket 301 is used to support the high-level liquid supply tank 302. It supplies liquid to the bubble generating device component unit 2 inside the deodorization chamber 1 through a U-shaped hose 303. The liquid in the high-level liquid supply tank 302 is transported to the bubble generating device component unit 2 under the action of siphon to supply liquid to it. A manual switch water valve 304 is set at the U-shaped hose 303 to control the liquid level in the bubble generating device.

[0042] Bubble generator component unit 2 blows out bubbles. These bubbles break due to the combined effects of airflow disturbance, gravity, and surface tension. The broken bubbles produce a large number of tiny droplets with a certain velocity. The microbial deodorizing agent within these droplets utilizes the physiological metabolic activities of microorganisms, such as oxidation-reduction, nitrification, and denitrification, to decompose and utilize harmful odorous gases as nutrients, ultimately generating CO2, H2O, and SO4. 2- and NO 3-These products are odorless and harmless, thus achieving the purpose of deodorization and odor removal.

[0043] The ammonia and hydrogen sulfide gas detector 4 is installed in the deodorization chamber to monitor the concentration of ammonia and hydrogen sulfide gas in real time and provide timely feedback on the deodorization effect.

[0044] Example 6

[0045] The system in this embodiment also includes a remote control device. The number and position of the bubble generating device component unit 2 are reasonably set according to the characteristics of the malodorous gases in the poultry and livestock farm. The installation height of the bubble generating device component unit 2 is the upper part of the deodorization chamber. The relative distance difference between adjacent bubble generating device component units 2 in the horizontal direction is between 130-150 cm. The height difference between adjacent bubble generating device component units 2 is about 1.5-2 m. The distance between the lowest bubble generating device component unit 2 and the upper surface of the poultry and livestock manure is about 1.5-2 m. Multiple bubble generating device component units 2 in the same horizontal plane are arranged in a four-corner arrangement, with the bubble outlet facing the center downwards, and the bubbles diffuse from the center to the edge.

[0046] In this embodiment, a liquid level sensor is installed inside the bubble generator of the bubble generator component unit to detect changes in the internal liquid level.

[0047] The remote control device is electrically connected to all bubble generator component units. The remote control device has a display screen and can simultaneously acquire data from the liquid level sensor and the ammonia and hydrogen sulfide gas detector 4. When ammonia and hydrogen sulfide gas are in excess, the bubble generator component unit is activated via the remote control to initiate bubble generation. When the liquid level is too low, the user manually adjusts the water valve 304 to supply liquid to the bubble generator.

[0048] Example 7

[0049] In this embodiment, a replenishment port is provided on the high-level liquid supply tank 302. The high-level liquid supply tank is made of transparent rigid material and has a lower limit scale for liquid level. When the liquid level is observed to be close to the lower limit scale, liquid is replenished manually through the replenishment port.

[0050] Example 8

[0051] In this embodiment, the high-level liquid supply tank 302 is equipped with a replenishment port, which is connected to an external storage tank. A pump replenishes the high-level liquid supply tank. A level sensor can also be installed inside the high-level liquid supply tank to monitor the liquid level. This level sensor can also be electrically connected to a remote control device. The high-level liquid supply tank is relatively large, and periodic replenishment is necessary when consumption is high.

[0052] This invention can reasonably control the operating time of the bubble generating device component unit 2 according to the characteristics of the malodorous gas concentration in poultry and livestock farms, thereby reasonably controlling the dosage of deodorizing solution consumed in bubble blowing.

[0053] In this invention, all bubble generating device components are of the same model and are connected in series, enabling overall control.

[0054] Example 9

[0055] In this embodiment, a replenishment port is provided on the high-level liquid supply tank 302, which is connected to an external storage tank. A pump replenishes the high-level liquid supply tank. A liquid level sensor is also installed inside the high-level liquid supply tank. The display screen of the remote control device shows the liquid level in the high-level liquid supply tank, and the remote control device is electrically connected to the pump. A replenishment button is provided on the remote control device. The remote control device is electrically connected to all bubble generating device component units. The remote control device is equipped with a display screen, a bubble blowing start button, and a bubble blowing stop button. The display screen can show the liquid level data and the concentrations of ammonia and hydrogen sulfide gases in the bubble generating device.

[0056] In this embodiment, the deodorization chamber 1 has a volume of 2.0m × 2.0m × 2.0m; the high-level liquid supply tank 302 has a volume of 30L; the bubble generating device in the bubble generating device component unit 2 has a size of 25cm × 15cm × 15cm, and the water tank of the bubble generating device component unit 2 has a volume of 300mL and a power of 13W, which can be directly purchased commercially.
