Abstract
The invention discloses an environment-friendly nitric acid purifying and refining device and a method thereof. The device comprises a reactor. The external wall of the reactor is provided with a cooling jacket. The upper end of the reactor is provided with a compressed air inlet pipe. The compressed air inlet pipe vertically penetrates the upper end of the reactor and stretch to the bottom of the reactor. A purification tank is arranged in the middle position in the reactor. One end of the purification tank is fixed on the internal wall of the reactor. The section, which is in the purification tank, of the compressed air inlet pipe is provided with a first air distribution disc. The section, which is under the purification tank, of the compressed air inlet pipe is provided with an electromagnetic valve. The tail end, which is under the electromagnetic valve, of the compressed air inlet pipe is provided with a second air distribution disc. The upper end of the reactor is also provided with an air exhaust pipe. The upper end of the air exhaust pipe is provided with a vacuum pump. The tail end of the air exhaust pipe is arranged in a liquid alkali absorption tank. The internal wall of the reactor is provided with a nitrogen monoxide probe and a nitrogen dioxide probe. The nitrogen monoxide probe and the nitrogen dioxide probe are connected to a micro processor. The micro processor is connected to the electromagnet valve. The lower end of the reactor is provided with a liquid discharge pipe. The provided device and method have the advantages that the operation is convenient and safe, and the purifying and refining effect is excellent.
