Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 with figure 2 It is a schematic description of the dual-circuit operation of the centrifuge cooling system before the transformation, image 3 is true figure 1 with figure 2 Changed to a schematic illustration of a single circuit.

[0024] Such as figure 1 As shown, the cooling water of the centrifuge is powered by the circulating water pump 1, enters the heat exchanger 6 through the cooling water inlet valve 3, and exchanges heat with the chilled water. After the temperature meets the operation requirements of the centrifuge, it is supplied to the centrifuge through the cooling water outlet valve 4 Machine, the reciprocating cycle continuously takes away the heat generated by the operation of the centrifuge.

[0025] Such as figure 2 As shown, the chilled water is powered by the circulating water pump 10, en...

Abstract

A non-contact transmission method of a local exhaust fan for nuclear feeding and taking comprises a centrifugal machine and comprises the following steps that S1, a cooling water return communicating valve is opened, a cooling water inlet valve is closed, a chilled water circulating water pump bypass valve is opened, operation of a chilled water circulating water pump is stopped, and the chilled water inlet valve is closed; centrifugal machine cooling water return water flows to the refrigerator evaporator from the centrifugal machine; and S2, a cooling water supply communication valve is opened, a chilled water outlet valve and a cooling water outlet valve are closed, and cooling water supply of the centrifugal machine flows to the centrifugal machine from the refrigerator evaporator. And S3, the outlet water temperature of the refrigerator evaporator is adjusted.

Description

technical field [0001] The invention belongs to the technical field of uranium enrichment production cooling, and in particular relates to a pipeline connection and operation method in which the cooling system of a centrifuge is changed from the operation of two circuits to the operation of one circuit. Background technique [0002] The existing centrifuge cooling system is a double-loop system, which is composed of two loops, the inner loop and the outer loop. The inner loop is a cooling water circulation loop, and the outer loop is a chilled water loop. The chilled water exchanges heat with the cooling water through a heat exchanger. Take away the heat generated when the centrifuge is running. Since the heat transfer is carried out indirectly through the heat exchanger, the cooling loss is large, the load rate of the refrigeration equipment is high, and the power consumption is high. In order to save energy and reduce consumption, the double circuit of the cooling system ...
