Embodiment 1

[0023] The method for long-distance transportation of condensate polishing resin of the present invention comprises the following steps:

[0024] The resin to be transported is first conveyed by hydraulic conveying, then conveyed by pneumatic conveying, and then conveyed by mixing hydraulic and pneumatic.

Embodiment 2

[0026] The system for long-distance delivery of condensate finishing resin in the present invention includes a resin delivery pipeline, a flushing water device and a compressed air system, wherein the outlet of the flushing water device, the outlet of the compressed air system and the inlet of the resin delivery pipeline are all connected to the resin The source node is connected, the outlet of the delivery pipeline is connected with the resin destination node, the resin delivery pipeline is provided with a pipeline sight glass monitoring device 4, the outlet of the flushing water device is provided with a first valve, and the outlet of the compressed air system is provided with a second valve. Two valves, the outer wall of the resin conveying pipeline is provided with antifreeze equipment.

[0027] When working, first open the first valve and close the second valve, use the flushing water output by the flushing water device as power to transport the resin in the resin source n...

Embodiment 3

[0029] refer to figure 1 , there are two resin transmissions in this embodiment, the first time: when the resin in the high-speed mixed bed 1 fails, the high-speed mixed bed 1 is used as the resin source node, and the high-tower separation tower 2 is used as the resin destination node to carry out the resin The second time: when the resin is regenerated and mixed, the resin mixing tank 3 is used as the resin source node, and the high-speed mixed bed 1 is used as the resin destination node for resin delivery.

[0030] In addition, during the conveying process, the resin conveying situation is observed through the pipe sight mirror monitoring device 4 .

[0031] The invention is applicable to the case where the regeneration equipment and the ion exchanger share a set of acid-base metering system for condensate polishing treatment resin and boiler supply water resin regeneration in a power plant, and can be used for active units and newly-built units.

[0032] The invention solv...

Abstract

The invention discloses a method and system for long-distance conveying of condensate polishing resin, and the method comprises the following steps: conveying to-be-conveyed resin in a hydraulic conveying manner, then conveying the to-be-conveyed resin in a pneumatic conveying manner, and then conveying the to-be-conveyed resin in a hydraulic and pneumatic mixed manner. The method and the system can effectively solve the problems of pipeline blockage and serious resin abrasion in long-distance resin transmission.

Description

technical field [0001] The invention relates to a method and a system for resin delivery, in particular to a method and a system for long-distance delivery of condensate polish treatment resin. Background technique [0002] The chemical design specification recommends that the resin delivery pipeline should not exceed 200m to prevent problems such as blockage of the delivery pipeline and serious wear of the resin due to the long delivery distance. Therefore, most power plant condensate polishing systems set the regeneration room near the high-speed mixed bed. Considering the safety of acid and alkali, the resin regeneration acid-base system for fine treatment and the boiler feed water resin regeneration acid-base system must also be set up separately, and the corresponding neutralization tanks must also be set up separately. The acid-base metering system for resin regeneration in actual boiler feed water is the same as the acid-base metering system for resin regeneration in...
