Description

Technical Field

[0001] The utility model relates to the technical field of black soldier fly breeding, in particular to a black soldier fly breeding tail gas deodorization system. Background Art

[0002] Black soldier flies, saprophytic insects of the family Solenopsis, can feed on livestock and poultry manure and domestic garbage to produce high-value animal protein feed. Due to their rapid reproduction, large biomass, wide diet, high absorption and conversion rate, easy management, low feeding cost, and good palatability for animals, they can be utilized as resources. They are currently widely used in the treatment of waste such as chicken manure, pig manure, and kitchen waste.

[0003] During the breeding process of black soldier flies, since their feed mainly consists of very easily corruptible organic matter such as feces and kitchen waste, the exhaust gas concentration produced after these organic matter are processed by the black soldier flies is relatively high. At the same time, black soldier flies also produce some dust during the breeding process, and this dust will be mixed in the exhaust gas. Therefore, the breeding exhaust gas of black soldier flies must be treated for environmental protection before it can be discharged to the outside. Most existing deodorization systems directly use chemical agents to deodorize and treat exhaust gas. However, the exhaust gas is often discharged to the outside before it fully reacts with the chemical agents, and the deodorization effect is not obvious. Utility Model Content

[0004] The purpose of the utility model is to provide a black soldier fly breeding tail gas deodorization system to address the deficiencies of the existing technology and solve the problems raised in the background technology.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A black soldier fly breeding exhaust gas deodorization system includes an exhaust gas treatment room, which includes a breeding area, a primary treatment area and a secondary treatment area. Several black soldier fly breeding equipment are placed in the breeding area. A multi-layer deodorizing water curtain is provided at one end of the primary treatment area close to the breeding area. The deodorizing water curtain is provided with a plurality of honeycomb holes. The honeycomb holes of each deodorizing water curtain are stacked and staggered to delay the passage time of the exhaust gas. A dripping device is provided at the top of the deodorizing water curtain. The dripping device is filled with a deodorizing agent so that the honeycomb holes of the deodorizing water curtain are covered with the deodorizing agent. A fan device is provided at one end of the secondary treatment area close to the primary treatment area. The top of the secondary treatment area is open and covered with a filter screen. A spray atomization device is provided below the filter screen. The spray atomization device is filled with a deodorizing agent so that the secondary treatment area is covered with deodorizing agent spray to perform secondary treatment on the exhaust gas.

[0007] As a preferred solution of the black soldier fly breeding exhaust gas deodorization system, the dripping device includes a return water trough arranged at the bottom of the preliminary treatment area, the return water trough is used to recover the deodorizing agent flowing into the ground, the return water trough is connected to a first return water pool, and a plurality of drip pipes are arranged at intervals along the thickness direction of the top of the deodorizing water curtain, the first return water pool is connected to the drip pipe through a first conveying pipe, and a plurality of drip holes are arranged at intervals along the length direction of the drip pipe below to facilitate the deodorizing agent to flow into the honeycomb holes in the deodorizing water curtain.

[0008] As a preferred solution for the black soldier fly breeding exhaust gas deodorization system, a first support frame is installed at the top of the secondary treatment area, a hook is provided above the first support frame, the filter net is laid on the first support frame and connected to the hook, and the first support frame and the filter net are both arc-shaped structures to increase the filtration area.

[0009] As a preferred solution for the black soldier fly breeding exhaust gas deodorization system, the spray atomization device includes a second return water tank arranged at the bottom of the secondary treatment area, and a plurality of spray atomizers are arranged at intervals below the first support frame. The spray atomizers are connected to the second return water tank through a second delivery pipe.

[0010] As a preferred solution of the black soldier fly breeding exhaust gas deodorization system, second support frames are provided on both sides of the deodorizing water curtain to support it.

[0011] As a preferred solution of the black soldier fly breeding exhaust gas deodorization system, the fan device includes a fan wall arranged at one end of the secondary treatment area close to the primary treatment area, and a plurality of fans are arranged at intervals on the fan wall.

[0012] Beneficial effects of the utility model:

[0013] The utility model adopts a structural design that combines a deodorizing water curtain with a dripping device. The tail gas from the breeding of black soldier flies will first enter the deodorizing water curtain, and the dripping device will continuously drip deodorizing agents into the inside of the deodorizing water curtain. Since the deodorizing water curtain adopts a stacked and staggered arrangement, it can effectively delay the passage time of the tail gas, so that the tail gas can fully react with the deodorizing agent. At the same time, since the honeycomb holes of the deodorizing water curtain are small, most of the dust included in the tail gas will also be blocked in the deodorizing water curtain. The tail gas passing through the deodorizing water curtain will enter the secondary treatment area under the action of the fan, and the spray atomizer in the secondary treatment area will spray the deodorizing agent. The tail gas after the secondary treatment will finally pass through the filter screen, and the remaining tiny dust entrained in the tail gas will be filtered and discharged to the outside. The utility model can effectively increase the reaction time between the tail gas and the deodorizing agent, and remove the dust entrained in the tail gas, and the deodorizing effect is more obvious.
