Problems solved by technology

However, when nitrogen is heated, due to the volume expansion of nitrogen when it is heated, and the heating container is relatively sealed, once the detection system fails, it is prone to physical explosion.
In addition, the nitrogen used ...

Abstract

The invention provides a nitrogen heater. The nitrogen heater comprises a cylinder with a gas storage space inside, a nitrogen inlet and a nitrogen outlet, wherein the nitrogen inlet and the nitrogenoutlet are arranged at two ends of the cylinder; at least one heat exchange tube is arranged in the cylinder; one end of the at least one heat exchange tube is connected with the nitrogen inlet, and the other end of the at least one heat exchange tube is connected with the nitrogen outlet; the cylinder is further provided with a steam inlet and a steam outlet which communicate with the gas storagespace; a plurality of baffle plates arranged in parallel are arranged between the steam inlet and the steam outlet in the cylinder; and every two adjacent baffle plates are arranged in a staggered manner. Heating is performed through heat exchange between steam and nitrogen; while it is guaranteed that the nitrogen can be heated to the enough temperature, the temperature of the nitrogen is not too high, so that damage to a precision device to be cleaned or dried is avoided, and meanwhile, the situation that the volume of the nitrogen is excessively expanded due to the fact that the nitrogen is excessively heated, thus avoiding the explosion of the cylinder.

Description

technical field [0001] The invention relates to the technical field of heating devices, in particular to a nitrogen heater. Background technique [0002] Nitrogen, chemical formula N 2 , usually a colorless and odorless gas, chemically inactive, it is difficult to react with other substances at room temperature, but it can undergo chemical changes with certain substances under high temperature and high energy conditions. Therefore, in industrial production and processing, nitrogen is often heated, and some precision devices are washed or dried with the heated nitrogen flow, which is simple and convenient and will not cause corrosion or damage to the product. [0003] At present, the commonly used nitrogen heating device in industrial production is nitrogen electric heater, which has high heating efficiency and is super convenient to use. However, when nitrogen is heated, due to the volume expansion of nitrogen when it is heated, and the heating container is relatively seal...
