Detailed Description

Referring to fig. 1-3, an anaerobic tank is provided. As shown in fig. 1, the air conditioner comprises a box body 1 and a controller, wherein an interlayer 2 is arranged in the box body 1, a heat-insulating layer made of glass wool is filled in the interlayer 2, partition plates 17 are arranged in parallel along the four walls and the bottom surface of the interlayer 2, and an air duct 3 for air circulation is formed by the partition plates 17 and the inner wall of the interlayer 2. A flute air outlet pipe 19, a heat exchanger 6, a heater 7 and a three-phase motor 9 are sequentially arranged at the bottom in the air duct 3. The air outlet pipe 19 of the flute is used for inputting air into the air duct 3, and the air outlet pipe 19 of the flute is connected with the nitrogen electromagnetic valve 10 and the flowmeter 11. The three-phase motor 9 is connected with the centrifugal impeller 8, and the centrifugal impeller 8 is arranged at the lower right corner in the air duct and used for pushing the air in the air duct 3 to the upper right. The box body 1 is provided with an oxygen concentration sensor 15 and a temperature sensor 16 which extend into the working area 20 and are used for measuring the gas content and the temperature in the working area 20. The outer surface of the box body 1 is also provided with a touch screen 4, the touch screen 4 is connected with a controller, and the nitrogen electromagnetic valve 10, the flowmeter 11, the oxygen concentration sensor 15 and the temperature sensor 16 are all connected with the controller and used for adjusting the gas flow and the temperature in the box body. The working area 20 is internally provided with an exhaust port 14 communicated with the outside of the box body 1, and the diameter of the exhaust port 14 is 40-60mm, so that redundant gas in the working area 20 is exhausted. The box body 1 is made of magnetic wiredrawing stainless steel; the inner chamber is made of nonmagnetic mirror stainless steel; the temperature sensor 16 employs a platinum resistor of Pt 100.

As shown in fig. 2, the partition 17 is made of stainless steel plate, and through holes 18 are uniformly distributed on the partition, and the through holes 18 are generally formed in an oval shape. The aperture of the through-hole 18 ranges from 10mm to 30 mm. The through holes 18 are used to uniformly transfer heat and air volume, ensuring uniform temperature in the working area 20.

As shown in fig. 3, the flute air-out pipe 19 includes a long cylindrical body, a plurality of flute air-out ports 12 are distributed on the flute air-out pipe 19, nitrogen enters the flute air-out pipe 19 from a pipeline, and then is sprayed out from the flute air-out ports 12 to flow into the air duct 3. The air outlet pipe 19 of the flute can make the air flow into the air duct 3 evenly.

When the temperature needs to be raised, nitrogen enters from the flute air outlet pipe 19, the heater 7 works at the moment, the gas is heated, and the gas circularly flows in the air duct 3 under the action of the centrifugal impeller 8 and flows to a working area from the partition plate air outlet 5, so that the temperature of the working area 20 is raised. And flows back into the air duct 3 from the partition return air inlet 13. The excess will be exhausted through the exhaust port 14. When the temperature of the working area 20 needs to be reduced, the air outlet pipe 19 of the flute inputs nitrogen into the air duct 3 to replace the gas with higher temperature in the air duct 3, and the heat exchanger 6 is opened at the moment, the heater 7 stops working, the temperature of the gas can be reduced when the gas passes through the heat exchanger 6, and the temperature of the gas in the air duct 3 can be reduced. The controller can sense the temperature of the working area 20 in time through the oxygen concentration sensor 15 and the temperature sensor 16, and make feedback control on the nitrogen electromagnetic valve in time, so that the air output of the air outlet 12 of the flute can be adjusted in time. Because the air outlet 12 of the flute is uniformly distributed on the air outlet pipe 19 of the flute and because the through holes 18 uniformly arranged on the partition plate form the partition plate air outlet 5 and the partition plate air return inlet 13, the anaerobic box has better temperature uniformity, thereby ensuring that the anaerobic box can provide a stable simulation test environment.
