Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A micro negative pressure mechanism of a wet garbage fermentation workshop is shown in figure 2 and comprises a plurality of air inlet pipes 1 (four air inlet pipes 1 are preferred in the embodiment) arranged on one side in the workshop, wherein the air inlet pipes 1 penetrate through the wall of the workshop and communicate the inside of the workshop with the outside of the workshop; a plurality of air outlet pipes 2 (preferably four air outlet pipes 2 are arranged on one side of the workshop, which is far away from the air inlet pipe 1), and the air outlet pipes 2 penetrate through the side wall of the workshop so as to communicate the inside and the outside of the workshop with each other; every goes out the one end rigid coupling that tuber pipe 2 is located the workshop outside and has a fan 21 to after fan 21 starts, form the negative pressure in the workshop, make fresh air enter into the workshop, and the foul air in the workshop passes through the outlet pipe and discharges, and then has improved the air quality in the workshop.

As shown in fig. 2, a first air valve 11 is coaxially and fixedly connected to the end of the air inlet pipe 1 located in the workshop, and a second air valve 22 is coaxially and fixedly connected to the end of the air outlet pipe 2 located in the workshop, so that when ventilation and air exchange are not performed in the workshop, the first air valve 11 and the second air valve 22 can be closed, so that malodorous molecules in the workshop are not easy to drift outdoors through the air inlet pipe 1 and the air outlet pipe 2, and the air environment outside the workshop is not affected.

As shown in fig. 3 and 4, a primary filtering mechanism 3 is further arranged at one end of the air outlet pipe 2 in the workshop. The primary filtering mechanism 3 comprises an accommodating box 31 fixedly connected to the end of the second air valve 22, the inside of the accommodating box 31 is communicated with the second air valve 22, a circulation port 311 for air flowing is formed in one side of the accommodating box 31 opposite to the second air valve 22, and an opening is formed in one side of the accommodating box 31; a filter assembly 32 for filtering the air is also inserted in the housing and inside.

As shown in fig. 4 and 5, the filter assembly 32 includes primary filters 321 arranged in parallel and at intervals, and an active filter layer 322 arranged between the two primary filters 321. The active filter layer 322 includes a mesh case 3221 made of a metal mesh, and activated carbon particles 3222 closely packed in the mesh case 3221.

After the filter assembly 32 is placed in the accommodating box 31, the fan 21 is started, and air inside the workshop is firstly filtered by the filter assembly 32 and then enters the air outlet pipe 2. The two-layer primary filter 321 can not only filter dust particles larger than 5 μm in the air, but also improve the filtering effect by a double-layer filtering mode; and the active carbon particles 3222 can adsorb part of the malodorous molecules in the air, thereby reducing the burden of subsequent air filtration of the air outlet pipe 2. And because the primary filter mechanism 3 is arranged in a workshop, the replacement efficiency of the filter assembly 32 is improved in an inserting mode, and the complexity of subsequent maintenance is greatly reduced.

As shown in fig. 6, a concentration pipe 4 is further disposed outside the workshop, and the concentration pipe 4 is communicated with the tail portions of all the fans 21. And the collecting duct 4 includes a downwardly extending portion 41 extending toward the bottom of the plant, a U-shaped portion 42 provided at the rear of the downwardly extending portion 41, and an upwardly extending portion 43 provided at the rear of the U-shaped portion 42, so that the U-shaped portion 42 is located at the lowest point of the collecting duct 4.

As shown in fig. 6 and 7, a secondary filtering mechanism 5 for filtering air inside the collecting duct 4 is provided at the U-shaped portion 42 of the collecting duct 4. The secondary filtering mechanism 5 comprises a medicine barrel 51 fixed on the ground; a water pump 52 arranged at one side of the medicine barrel 51, wherein the water inlet of the water pump 52 is communicated with the interior of the medicine barrel 51; the water outlet of the water pump 52 is connected with an extension pipe 53, the other end of the extension pipe 53 is connected with an atomizing nozzle 54, and the atomizing nozzle 54 is arranged on the upper wall of the middle part of the U-shaped part 42 of the concentration pipe 4 in a penetrating mode. When the secondary filtering mechanism 5 works, the water pump 52 is started to drive the deodorant in the medicine barrel 51 to enter the extension pipe 53, and the medicine is uniformly sprayed on the U-shaped part 42 of the concentration pipe 4 through the atomizing nozzle 54 to form a mist; at this time, the air passes through the 4U-shaped part 42 of the concentration pipe, so that the air is fully contacted with the medicament, the contact area of the malodorous molecules in the air and the medicament is increased, the medicament and the malodorous molecules have a positive skiing reaction, and the tasteless molecules are generated, so that the deodorizing effect is achieved. Since the U-shaped portion 42 of the concentration tube 4 is located at the lowest point of the concentration tube 4, even if the spray of the chemical flows toward the upper extension portion of the concentration tube 4 by the air, the chemical contacts the inner wall of the concentration tube 4 and forms water drops, and gathers toward the bottom of the U-shaped portion 42 under the action of gravity and remains at the bottom of the U-shaped portion 42. And the tail part of the concentration pipe 4 is connected with other air processing equipment, so that the standard of air exhaust to outdoor air is achieved.

As shown in fig. 7 the bottom rigid coupling of concentrating pipe 4U type portion 42 has a drain pipe 61, drain pipe 61 with concentrate inside intercommunication of pipe 4 to the end connection of drain pipe 61 has a valve 62, thereby the staff can be according to the inside water level condition of concentrating pipe 4U type portion 42, to concentrating the inside operation of decontaminating of pipe 4, thereby has ensured the normal work of concentrating pipe 4.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
