Description

Technical Field

[0001] The present invention relates to a modular deodorizing device that is built and installed on the top of a tunnel fermentation bin by utilizing the special structure of the tunnel fermentation bin. More specifically, it relates to a modular deodorizing device that integrates the device into one, is located on the top of the tunnel fermentation bin and is integrated with the bin structure, does not require any collection pipelines, and is highly efficient in energy saving and consumption reduction. Background Art

[0002] The aerobic composting process will produce a large amount of odor, the main components of which include ammonia, hydrogen sulfide, VOC, etc., as well as a large amount of water vapor. If it is not collected and treated, it will cause secondary pollution to the surrounding environment.

[0003] The dynamic tunnel fermentation chamber is a new aerobic composting chamber type. The shape of the entire chamber is similar to a rectangular pipe and has good sealing properties. At present, deodorization generally adopts the method of setting an odor collection port at the chamber entrance or inside the chamber, and then the odor is transported to the terminal deodorization device through a pipe for treatment. This deodorization system brings the following problems:

[0004] (1) The distance of the odor transmission pipeline is long, which requires pipeline investment and power consumption.

[0005] (2) Odors escape from the pile at a high temperature. Hot air has upward kinetic energy, so the lateral collection effect is poor and the energy consumption is high.

[0006] (3) The odor concentration and corrosiveness generated at different positions of the pile are different. Under the current operating mode, all odor needs to pass through the tunnel fermentation bin, especially the tail of the bin, causing significant corrosion to the tunnel fermentation bin and the exposed tracks, equipment walking treads, and cables.

[0007] (4) When the deodorization capacity of individual tunnel fermentation bins needs to be increased after operation, it is not feasible to do so. Summary of the invention

[0008] In view of this, the main purpose of the present invention is to provide a top-mounted modular deodorizing device for a tunnel fermentation bin, which can solve the main problems existing in the current tunnel composting deodorizing composting system.

[0009] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0010] Provided is a top-mounted modular deodorization device for a tunnel fermentation bin, including: a double guide support plate, a supporting layer, a filler, a spray device, a spray control valve, a fan, an exhaust pipe, and a condensed water collection tank. According to the structural characteristics of the tunnel-type tunnel fermentation bin, the odor generated in the bin is concentrated on the top of the tunnel fermentation bin and flows autonomously toward the end of the bin; n groups of modular deodorization devices are installed on the top of a tunnel fermentation bin, n = 1 to 100; wherein the double guide support plate is embedded in the tunnel fermentation bin, and the odor passes through the double guide support plate and the supporting layer under the action of negative pressure and enters the filler, and the condensed liquid on the double guide support plate is discharged through the condensed water collection tank at the bottom thereof; a spray device is arranged above the filler, and the spray water volume is adjusted by the spray control valve, and the odor substances are removed under the action of the microorganisms attached to the filler, and the gas that meets the emission standards is discharged into the surrounding environment through the exhaust pipe under the action of the fan.

[0011] The above systems work together to complete the deodorization process of the tunnel fermentation bin and achieve the following goals: (1) No pipeline is required for odor transportation, saving pipeline investment and power consumption; (2) The upward kinetic energy of the odor is fully utilized to improve the collection effect and reduce energy consumption; (3) The odor generated at different positions of the pile is collected nearby, reducing the corrosion of the tunnel fermentation bin and the exposed tracks, equipment walking treads, and cables. (4) After operation, if the deodorization capacity of individual tunnel fermentation bins needs to be increased, it can be added at any time.

[0012] The above-mentioned double flow guide support plate is made of a material with thermal conductivity, and has the triple functions of backflow, support and condensation. Its height matches the embedding size of the deodorizing device, its top length matches the length of the deodorizing packing layer, and its bottom length matches the size of the condensate collection tank. The thickness meets the structural support strength requirements, and the bottom bevel is provided with a heaped roll edge to collect the condensed liquid on the double flow guide support plate.

[0013] The supporting layer is a filler support component, and the through-pore size is smaller than the filler size to ensure that the filler does not fall off.

[0014] The filler mentioned above is a filler containing carbon source material used in biological deodorization.

[0015] Among them, the above-mentioned spraying device is a spraying humidifying device, which is composed of a pipeline and a nozzle, and the working range of the nozzle covers the entire upper surface of the packing layer.

[0016] Among them, the above-mentioned spray control valve is an electrically controlled, pneumatically controlled or manually controlled valve, which is used to control the opening and stopping of the spray device.

[0017] Among them, the above-mentioned fan is a centrifugal fan with a pressure range of 100 to 3000Pa, and the air volume is determined according to actual conditions.

[0018] Wherein, the above-mentioned exhaust pipe is made of metal or fiberglass material.

[0019] The condensed water collecting tank is arranged at the lowermost end of the entire deodorizing device to collect the condensed water and spray water generated by the device. BRIEF DESCRIPTION OF THE DRAWINGS
