Description

Technical Field

[0001] The utility model relates to the field of amino acid processing, in particular to a tail gas recovery device with an automatic switch for amino acid purification. Background Art

[0002] Amino acids are important components of biological organisms and are the basic units that make up proteins. They have extremely important physiological functions. When purifying and refining most amino acids, they need to be heated, dissolved, filtered, concentrated, cooled and crystallized. When performing these processes, a large amount of tail gas will be released. Since these tail gases are weakly acidic and have a special smell, the tail gas is directly discharged into the air, which will seriously pollute the environment.

[0003] Existing tail gas absorption devices need to process tail gas when absorbing tail gas. When the emission volume is large and it is not absorbed in time, the tail gas will be discharged into the air without being fully absorbed, thus affecting the environment. However, the treatment structure inside the tail gas absorption device cannot completely process the tail gas, resulting in the incomplete treatment of the tail gas being discharged into the air, so that the tail gas still pollutes the environment, reducing the treatment effect of the tail gas absorption device. Utility Model Content

[0004] The purpose of the utility model is to provide an exhaust gas recovery device with automatic switch for amino acid purification. By setting a monitoring component and a switch component, the air intake passage can be closed in time when the exhaust gas volume is large, so that the exhaust gas can be fully treated before being discharged, thereby solving the above-mentioned problems existing in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0006] An exhaust gas recovery device with automatic switch for amino acid purification includes an air storage box, which is connected to an exhaust gas treatment box. An air intake pipe is provided at one end of the air storage box, a monitoring component is provided on the top of the air storage box, a switch component is provided in the air intake pipe, and the switch component and the monitoring component are electrically connected to a controller in sequence.

[0007] Preferably, the monitoring assembly includes a sleeve and a piston rod located in the sleeve, a spring is provided between the sleeve and the piston rod, an infrared sensor is provided at the bottom end of the sleeve, and the bottom end of the piston rod contacts or moves away from the infrared sensor.

[0008] Preferably, the air intake pipe comprises an inner tube and an outer tube, an automatic telescopic rod is provided between the tops of the inner tube and the outer tube, the telescopic end of the automatic telescopic rod is connected to a folding plate for opening or closing the inner tube channel, and the bottom end of the folding plate is connected to the outer tube.

[0009] Preferably, a slot hole is provided in the inner tube, and the folding plate folds up and down in the slot hole.

[0010] Preferably, sealing strips are provided on both sides of the slot, and the folding plate is located between the two sealing strips.

[0011] Preferably, the air inlet end of the outer tube is provided with a flange, and the inner tube is provided with an adsorption plate.

[0015] The utility model has the beneficial effects:

[0016] The utility model provides a monitoring component, which determines the relationship between the piston rod and the infrared sensor according to the volume of the exhaust gas. When the piston rod contacts the infrared sensor, the controller will drive the telescopic end of the automatic telescopic rod in the switch component to drive the folding plate to move up, thereby the folding plate closes the air intake passage of the intake pipe; the volume of the exhaust gas in the air storage box is reduced after being fully treated, and the piston rod is thus separated from the infrared sensor.

[0032] In some preferred embodiments, sealing strips 431 are provided on both sides of the slot 430, and the folding plate 42 is located between the two sealing strips 431.
