Overhead modular deodorization device for tunnel fermentation bin

Abstract

The invention discloses an overhead modular deodorization device for a tunnel fermentation bin, wherein the device is mounted at the top of the tunnel fermentation bin, a double-flow-guide support plate is embedded in the tunnel fermentation bin, and odor enters a filler through the double-flow-guide support plate and a bearing layer under the action of negative pressure; liquid condensed on the double-flow-guide support plate is discharged through a condensate water collecting tank at the bottom of the double-flow-guide support plate; and a spraying device is arranged above the filler, the spraying water amount is adjusted through a spraying control valve, odor substances are removed under the action of microorganisms attached to the filler, and gas meeting the emission standard is discharged into the surrounding environment through an exhaust funnel under the action of a fan. The device is composed of the double-flow-guide supporting plate 1, the bearing layer 2, the filler 3, the spraying device 4, the spraying control valve 5, the fan 6, the exhaust funnel 7 and the condensate water collecting tank 8.

Description

technical field [0001] The invention relates to a modular deodorization device constructed and installed on the top of the tunnel fermentation bin by utilizing the special structure of the tunnel fermentation bin. More specifically, it relates to a modular deodorization device that integrates equipment, is located on the top of the tunnel fermentation bin and merges with the bin structure, does not require any collection pipelines, and is highly efficient, energy-saving and consumption-reducing. Background technique [0002] The aerobic composting process will produce a large amount of odor. The odor components mainly include ammonia, hydrogen sulfide, VOC, etc. and a large amount of water vapor. If not collected and treated, it will cause secondary pollution to the surrounding environment. [0003] The dynamic tunnel fermentation bin is a new type of aerobic composting process bin. The shape of the whole bin is similar to that of a rectangular pipe and has good sealing. At...

AI Technical Summary

Problems solved by technology

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

[0005] (2) The odor escapes from the pile, the temperature is high, the hot air has upward kinetic energy, the horizontal collection effect is not good and the energy consumption is large

[0006] (3) The concentration and corrosiveness of the odor produced by different positions of the stack are different. Under the current operation mode, all the odor needs to pass through the tunnel fermentation bin, especially the position at the end of the bin, and travel to the tunnel fermentation bin and exposed tracks and equipment Great corrosion caused by treads and cables

[0007] (4) It is not feasible to realize the need to increase the deodorization capacity of individual tunnel fermentation bins after operation
