What are the requirements for safety technology management of gas cylinder filling units

 The following matters should be noted in the use of the oil cooler.

The temperature condition adjustment of the cooler (or switching heat exchanger) is based on the central temperature. The "middle" mentioned here does not refer to the central position of geometric dimension, but refers to the temperature on the barrel (or switching channel) near the central air extraction or the outlet of circulation. It is also related to the location where the thermometer is installed. The purpose of temperature condition adjustment is to keep the temperature difference between cold end and hot end within the specified range. Then, why should the temperature in the middle prevail? We need to take a look at the relationship between the temperature of the middle part and the temperature difference of the cold end and the temperature difference of the hot end, and what rules the temperature changes along the height direction of the cooler (or the switching heat exchanger) follow. The temperature condition change of the cooler (or switching heat exchanger) is general...

I. Preface With the rapid development of industry, nitrogen has been widely used in chemical engineering, electronics, metallurgy, food, machinery and other fields. The demand for nitrogen in our country increases at a speed of more than 8% every year. The chemical property of nitrogen is not active, and it shows great inertia under normal conditions, so it is not easy to react with other substances. Therefore, nitrogen is widely used as protective gas and sealing gas in metallurgical industry, electronic industry and chemical industry. Generally, the purity of protective gas is required to be 99.99%, and some require high purity nitrogen of more than 99.998%. Liquid nitrogen is a relatively convenient cold source, which is more and more widely used in food industry, medical service and the seminal storage of animal husbandry. During the production of synthetic ammonia in the chemical fertilizer industry, if the mixture of hydrogen and nitrogen, the feed gas of synthetic ammonia, is...

What are the main applications of throttling effect refrigeration capacity in air separation equipment?

1. The removal of perlite site shall be supervised by full-time personnel and guided by professionals. The principle of who organizes, who takes responsibility shall be followed. There should be a safe passage and a warning line at the removal of perlite site, and it is strictly forbidden to enter. 2. Dry air shall be used to warm the sand during the removal and knock the cold box to remove the pearlite caking, so as to prevent equipment damage caused by falling caking. 3. The removal of perlite should be carried out in layers and sand holes should be opened at different heights of the cold box. (It can be adjusted according to the site conditions) 4. In the process of removal of perlite, always supervise the caking on the top and enter the cold box for cleaning at any time. 5. In case of severe weather such as rain, snow, strong wind or sand storm danger, the construction party and the owner shall jointly confirm that the sand stripping work shall be postponed. 6. Remov
