Abstract

The invention provides a refrigeration tower of a superconduction iron remover and a control method. The refrigeration tower comprises a refrigeration tower body and a heating control device. The refrigeration tower body at least comprises a refrigerator, an outer barrel used in cooperation with the refrigerator, and a low-temperature liquid helium duvel. The heating control device is partially or completely arranged on the refrigeration tower body. The heating control device detects the air pressure value in the low-temperature liquid helium duvel, and if the detected air pressure value is smaller than the preset lowest air pressure value, the heating control device starts the heating function. According to the refrigeration tower of the superconduction iron remover and the control method, the problems that in the prior art, icing is likely to happen in a refrigeration tower of a superconduction iron remover, and consequently normal work of the refrigeration tower is influenced are solved.

Description

technical field [0001] The invention relates to the field of coal, in particular to a cooling tower of a superconducting iron remover and a control method. Background technique [0002] When processing raw coal, because the miscellaneous iron in the raw coal hinders the effective operation of the coal crusher in the power plant, and the gun wire in the raw coal has the danger of causing fire and explosion, it is necessary to remove the miscellaneous iron and gun wire in the raw coal . [0003] In the prior art, when the superconducting iron remover is used to remove the miscellaneous iron and shot wire in the raw coal, the external air will infiltrate into the inside of the superconducting iron remover, which will block the internal passage of the superconducting iron remover and affect the superconducting iron remover and sometimes it will affect the operation safety of the superconducting iron remover, because once the internal pressure rises sharply, the equipment will b...
