Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen production equipment, and specifically, to a nitrogen production equipment with high efficiency and energy saving. Background Technique

[0002] The nitrogen production equipment uses air as raw material and separates oxygen and nitrogen in it by physical methods. When high purity of nitrogen is required, the crude nitrogen needs to be purified. In the carbon carrier purification process, the crude nitrogen is heated and then reacts with the carbon purification agent. After the reaction, oxygen in the crude nitrogen can be removed, and the purity of nitrogen can be further improved. In the further purification process of nitrogen, the nitrogen needs to be heated, and the heated nitrogen needs to be cooled after the reaction.

[0003] In the prior art, a nitrogen production equipment with high efficiency and energy saving, with the Chinese patent application number 202022608752.X, includes a heater and a purification tower connected to the outlet of the heater, and also includes: a connecting pipe, a cooling box, an outlet, a cooling water pipe, a water storage tank, a circulating component, a collecting hood, a driving shaft, blades and a reciprocating component; one end of the cooling box is communicated with the cooling box through the connecting pipe, and the other end of the cooling box is provided with an outlet. When the purified crude nitrogen enters the cooling box, after the current collection by the collecting hood, it pushes the blades to rotate. The blades drive the driving shaft to rotate, and the driving shaft drives the circulating component to reciprocate through the reciprocating component. The circulating component pumps the water in the water storage tank into the cooling water pipe in a reciprocating manner, so that the coolant that has absorbed heat in the cooling water pipe enters the water storage tank. The heat in the water storage tank volatilizes through the heat dissipation fins, thereby enabling good circulation of the cooling water and improving the cooling effect. However, when it is in use, the crude nitrogen needs to be fully heated and then cooled down, increasing the energy consumption.
