Problems solved by technology
[0002] The existing crushing gas source for cryogenic crushing is injected directly through liquid nitrogen. However, the heated nitrogen gas collected in the crushing chamber is generally collected and then cooled to form liquid nitrogen, which is then used for cryogenic crushing. The temperature rise of the heated nitrogen gas is not large, and now it is directly cooled again to form liquid nitrogen, so that the original low temperature cannot be used again, and the liquid nitrogen in the tank storing cryogenic crushed liquid nitrogen will be vaporized, and the gas The existing process of liquefied liquid nitrogen cannot be used reasonably, so the existing cryogenic crushing process has a relatively low utilization rate of energy

The invention provides a cooling technology of a crushing air source for deep-cold crushing. By means of the cooling technology, gas obtained through gasification of liquid nitrogen can be used for cooling crushing compressed gas, then the crushing compressed gas can be used for cooling materials again, therefore, the utilization rate of energy sources is increased, and the production cost is reduced. The cooling technology comprises the steps that the crushing compressed gas obtained from a crushing cavity is introduced into a finned tube inlet of a fin type heat exchanger, a finned tube outlet of the fin type heat exchanger is communicated with a coil tube inlet of a liquid nitrogen storage tank coil tube heat exchanger, crushing frozen compressed gas flows out of a coil tube outlet of the liquid nitrogen storage tank coil tube heat exchanger and is introduced into the crushing cavity, liquid nitrogen is contained in a cavity of the liquid nitrogen storage tank coil tube heat exchanger, a shell of the liquid nitrogen storage tank coil tube heat exchanger is provided with a gasified gas outlet, the gasified gas outlet is communicated with a cavity of the fin type heat exchanger through a pipeline to serve as a heat exchange medium, and a heat exchange gas outlet is formed in the shell of the fin type heat exchanger and externally connected with a storage tank.
Description
technical field [0001] The invention relates to the technical field of material crushing, in particular to a cooling process of a crushing gas source for cryogenic crushing. Background technique [0002] The existing crushing gas source for cryogenic crushing is injected directly through liquid nitrogen. However, the heated nitrogen gas collected in the crushing chamber is generally collected and then cooled to form liquid nitrogen, which is then used for cryogenic crushing. The temperature rise of the heated nitrogen gas is not large, and now it is directly cooled again to form liquid nitrogen, so that the original low temperature cannot be used again, and the liquid nitrogen in the tank storing cryogenic crushed liquid nitrogen will be vaporized, and the gas The existing process of liquid nitrogen cannot be used reasonably, so the existing cryogenic crushing process has a relatively low energy utilization rate. Contents of the invention [0003] In view of the above pro...
