Nitrogen water pre-cooling system (1) system insulation. For the liquid level meter below the air cooling tower, the liquid level automatic regulator and other facilities should adopt anti-freezing measures in winter (especially in cold areas) to prevent the liquid level adjustment system from failing due to freezing. The adjustment system of the nitrogen water pre-cooling system designed by the hospital for the oxygen station of Jiyuan Smelter is placed in a special small room with lighting, heaters and instrumentation wrapped around the electric heating belt. In addition, when the air cooling tower and the water cooling tower are arranged outside the main building, and the water pump is arranged in the main building, the connecting water pipes between them (often laid in the trench) should be insulated to prevent the water in the pipe from freezing in winter. And swell the water pipe and the valve on the pipeline. When the lower part of the air cooling tower is indoors and the upper part is outdoors, heat insulation measures should be taken to prevent the instrument tube from freezing. (2) Pipe brackets shall not be welded on the air cooling tower. The installation instructions for the air cooling tower are generally specified: During the installation of the air cooling tower, the tower body is strictly prohibited from moving fire, so as to avoid damage to the paint inside the tower. Another reason why the bracket cannot be welded on the air cooling tower body is because the working pressure in the cooling tower is about 016 MPa, which belongs to the pressure vessel range. Too high or too low will affect its fuel supply efficiency, but in actual design, due to the limitations of the site conditions, it is difficult to meet the installation height specified by the manufacturer. Therefore, the designer should contact the manufacturer's personnel in time to ensure that the installation height of the high fuel tank is within the feasible range. The supply peephole of the high fuel tank shall be installed on the return pipe in accordance with the requirements of the manufacturer, not on the oil pipe. If the high fuel tank is installed outdoors, in order to prevent the oil temperature in the winter from being too low, a steam coil heating device should be provided outside the tank to maintain a certain oil supply temperature.
