A gas-liquid separation deodorization spraying device for landfills

Abstract

This utility model discloses a gas-liquid separation deodorization spraying device for landfills, including a front-end treatment device, a spraying device, and a waste gas dissolving device. The front-end treatment device is positioned above the landfill, and is connected to the spraying device via a first pipe. An air suction pump is installed on the first pipe to draw in odorous gases generated from the landfill, and the front-end treatment device performs gas-liquid separation on the odorous gases. This utility model employs a two-stage dissolving process: the spraying device and the waste gas dissolving device, targeting both readily soluble and poorly soluble odor components respectively, ensuring that the odors are fully and thoroughly dissolved and removed. The U-shaped tube design forces the odorous gases to penetrate the deodorizing agent, significantly improving the contact efficiency and dissolution effect between the poorly soluble gases and the deodorizing agent.

Description

Technical Field

[0001] This utility model relates to a spraying device, specifically a gas-liquid separation deodorization spraying device for landfills. Background Technology

[0002] Existing spray / sprinkler deodorization devices mainly rely on the surface contact between atomized deodorizing agents and gases. They are effective for odor components that are easily soluble in liquids (such as ammonia), but have limited removal efficiency for odor components that are difficult to dissolve in liquids (such as hydrogen sulfide and some volatile organic compounds, VOCs). The gas may be discharged before it is fully dissolved, resulting in incomplete deodorization and the risk of odor or exceeding standards in the exhaust gas.

[0003] Odors from landfills typically contain large amounts of water vapor, leachate droplets, dust, and particulate matter. If current technologies do not effectively separate these liquid water and solid impurities, the water entering subsequent dissolution units will dilute the deodorizer concentration, reducing its chemical reaction efficiency and increasing deodorizer consumption. Impurities and solid particles in the water easily clog atomizing nozzles, leading to uneven spraying or even failure, requiring frequent maintenance. Furthermore, dust-laden moisture accelerates corrosion and scaling in pipes and equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a gas-liquid separation deodorization spraying device for landfills, so as to solve the problems existing in the background art.

[0005] The gas-liquid separation deodorization spraying device for landfills of this utility model is achieved through the following technical solutions, including a front-end treatment device, a spraying device, and a waste gas dissolution device.

[0006] The front-end processing device is positioned above the landfill. The front-end processing device is connected to the spraying device via a first pipe, and an air suction pump is installed on the first pipe. The air suction pump is used to draw in the odor generated by the landfill, and the front-end processing device performs gas-liquid separation on the odor.

[0007] The spraying device is connected to the waste gas dissolving device through a second pipe. The deodorizing agent is sprayed through the spraying device to dissolve the easily soluble odor components. The odor components that are not easily soluble enter the waste gas dissolving device through the second pipe and are immersed in the deodorizing agent through the U-shaped tube, so that they can fully contact the deodorizing agent and completely dissolve in the deodorizing agent.

[0008] The other end of the waste gas dissolution device is equipped with a third pipe, and an exhaust pump is installed on the third pipe to discharge the treated odorous gas.

[0009] As a preferred technical solution, the front-end processing device includes an air inlet seat and a dustproof seat;

[0010] The dustproof seat is fixed to the air inlet end of the air inlet seat by a guide structure and is secured by screws. A dustproof net is provided at the lower end of the dustproof seat, and a connecting ring is provided on the upper inner side of the dustproof seat. A waterproof and breathable membrane is fixed on the connecting ring. The waterproof and breathable membrane achieves gas-liquid separation, so that the odor entering the first pipe is in a dry state.

[0011] As a preferred technical solution, the spraying device includes a spraying box and an atomizing nozzle, with the atomizing nozzle installed at the top inside the spraying box; the bottom of the spraying box has a conical structure, and a first drainage pipe is provided at the bottom of the spraying device to facilitate the discharge of the deodorizing agent that dissolves odors.

[0012] As a preferred technical solution, the waste gas dissolution device includes a dissolution tank and a U-shaped pipe connected to a second pipe; the U-shaped pipe is immersed in the deodorizing agent in the dissolution tank, so that the odor and the deodorizing agent are fully dissolved; a second drainage pipe is provided at the bottom of the dissolution tank.

[0013] As a preferred technical solution, both the first drainage pipe and the second drainage pipe are connected to an external wastewater treatment tank, and valves are installed on both the first drainage pipe and the second drainage pipe.

[0014] As a preferred technical solution, a conveying pipe is provided above the spraying device and the waste gas dissolving device, through which deodorizing agent is supplied to the atomizing nozzle and the dissolving tank; valves are provided on the conveying pipe.

[0015] The beneficial effects of this utility model are:

[0016] This invention employs a two-stage dissolution process consisting of a spraying device and a waste gas dissolution device, targeting both readily soluble and sparingly soluble odor components to ensure that the odor is fully and thoroughly dissolved and removed. The U-shaped tube design forces the odor to immerse itself in the deodorizing agent, significantly improving the contact efficiency and dissolution effect between sparingly soluble gases and the deodorizing agent.

[0017] This invention effectively separates liquid water from odorous gases through a waterproof and breathable membrane in the front-end treatment device, ensuring that the gas entering the subsequent treatment unit is in a dry state; it avoids the liquid water diluting the concentration of the subsequent deodorizing agent and reducing the dissolution efficiency, while preventing the atomizing nozzle from clogging and ensuring stable and efficient operation of the spraying and dissolution process; the dustproof net effectively intercepts solid particles, protecting the waterproof and breathable membrane and subsequent pipeline equipment.
