Abstract

The utility model relates to a draining waste steam pre-heating water supplying system of a thermal deaerator and belongs to the field of draining waste steam recycling of the thermal deaerator. A steam discharging opening of the deaerator is connected with a heat exchanger which is connected with a deaerating water tank. The deaerator is installed on the deaerating water tank. A softened water supplying pipeline is connected with the heat exchanger and then connected to the deaerator. A steam discharging pipe is arranged on the top of a steam discharging and introducing side of the deaerator of the heat exchanger. The draining waste steam pre-heating water supplying system of the thermal deaerator has the advantages that discharged steam of the deaerator is directly recycled, a pre-heating boiler is used for softening water and supplying water, the waste of resources is reduced, heat energy recycling is achieved and the heat efficiency of the boiler is improved.

Description

The emptying remaining vapour of thermal deaerator preheats water supply system
Technical field
The utility model belongs to the emptying remaining vapour recycling of thermal deaerator field.
Background technology
The demineralized water that boiler of feeding is used (containing supplementing water) is after inlet regulating valve is regulated, enter oxygen-eliminating device, with other, each road is hydrophobic in oxygen-eliminating device, mixes, through pipe ejection with holes, form skirt shape moisture film, carry out hybrid heat transfer and mass transfer with heating steam, feedwater reaches rapidly the saturation temperature under operating pressure.Now, the most of dissolved oxygen in water and other gas are resolved out basically, reach the purpose of deoxygenation.The dissolved oxygen of separating out from water and other gas constantly from the gland steam exhauster at oxygen-eliminating device top with remaining vapour displacer.Deaerated water boiler of feeding after feed pump boosts is used.The dissolved oxygen of separating out from water in thermal deaerator work, water vapour and other gas (comprise free state CO 2, N 2) constantly from the gland steam exhauster at oxygen-eliminating device top, with remaining vapour, discharge, directly to sky, discharge has caused the wasting of resources to this part exhausted spare heat.
Summary of the invention
Technical problem to be solved in the utility model is: how to reclaim gland steam exhauster and discharge this part heat energy with remaining vapour, realize heat energy recycling.
The technical scheme that the utility model adopts is: the emptying remaining vapour of thermal deaerator preheats water supply system, the deaerator exhaust mouth connects heat exchanger, heat exchanger 2 is connected with the deoxygenation water tank, oxygen-eliminating device is arranged on the deoxygenation water tank, demineralized water make-up water pipeline is connected on oxygen-eliminating device 5 after connecting heat exchanger, and the deaerator exhaust of heat exchanger is introduced side roof part and is provided with blast pipe.Deaerator exhaust is introduced in heat exchanger, again introduce the deoxygenation water tank after condensate water, the cooling water of described heat exchanger carrys out the demineralized water make-up water to oxygen-eliminating device, and the deaerator exhaust of described heat exchanger is introduced side roof part and is provided with blast pipe, in exhaust steam, institute is oxygenous, prevents from causing the corruption of heat exchanger oxygen.
The beneficial effects of the utility model are: directly reclaim deaerator exhaust, and the moisturizing of preboiler demineralized water, reduced the wasting of resources, realized heat energy recycling, improved boiler thermal output.
The accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present utility model;
Wherein, 1, remaining vapour is emptying, 2, heat exchanger, 3, oxygen is emptying, 4, condensed water, 5, oxygen-eliminating device, 6, the demineralized water make-up water, 7, the deoxygenation water tank, 8, remove feed pump.
The specific embodiment
The emptying remaining vapour of thermal deaerator preheats water supply system, oxygen-eliminating device 5 steam discharges are introduced in heat exchanger 2, again introduce the deoxygenation water tank after condensate water, the cooling water of described heat exchanger carrys out the demineralized water make-up water to oxygen-eliminating device, the deaerator exhaust of described heat exchanger is introduced side roof part and is provided with blast pipe, in exhaust steam, institute is oxygenous, prevents from causing the corruption of heat exchanger oxygen.The utility model directly reclaims deaerator exhaust, and the moisturizing of preboiler demineralized water, has reduced the wasting of resources, has realized heat energy recycling, has improved boiler thermal output.
On the Q403/567-77-3.85/450 boiler that 2010 manufacture in Hangzhou Boiler Factory, implement, 1.5 ten thousand tons of year recovery condensed waters, energy recovery 1.2 ten thousand GJ, realize 350,000 yuan of economic benefits.
On QC400 (400)/400 (300)-54 (17) boilers of manufacturing in Hangzhou Boiler Factory in 2011, again implement, respond well.
