Description
Technical field
The present invention relates to a kind of boiler heat-energy recovering apparatus, particularly a kind of exhaust recovery device of deaerator.
Background technology
In the production process of industrial enterprise that boiler is arranged and electric power enterprise, the deoxygenation mode of boiler feedwater adopts the thermal de-aeration mode usually, to guarantee the quality of feedwater.This deoxygenation mode has simply, the reliable and good advantage of deaerating effect; But the steam that oxygen-eliminating device produces generally directly is discharged in the atmosphere, has not only increased the airborne release amount, and environment is caused thermal pollution; And contained heat is not utilized in the steam, has wasted the energy.According to measuring and calculating; 100 tons the air suspended type oxygen-eliminating device of exerting oneself, under normal operation, water temperature reaches 104 ℃ and oxygen-eliminating device internal pressure and reaches 0.02MPa when above in the oxygen-eliminating device; The quantity of steam that per hour is discharged into atmosphere reaches the 0.5-0.7 ton; Under the situation of intensification and recycling economy conversion,, will produce huge economic benefit in present world energy supplies growing tension and China as and if being used with this part Steam Recovery.
Summary of the invention
Technical problem to be solved by this invention provides a kind of exhaust recovery device of deaerator, and it can reduce the airborne release amount with the heat in the steam of recycling the oxygen-eliminating device discharge, has practiced thrift the energy, has protected environment, and is simple in structure, easy to use.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is: a kind of exhaust recovery device of deaerator, comprise the packed tower housing, and the filler in the packed tower housing is divided into packing layer and following packing layer; The packed tower case top is provided with exhaust outlet; Packed tower housing top is provided with cooling water inlet, and the packed tower lower housing portion is provided with steam inlet and hot water outlet successively, and the circulating hot water import is located on the packed tower housing between packing layer and the following packing layer; Outlet conduit one end is communicated with hot water outlet; The outlet conduit other end is communicated with the import of two water pumps respectively, and the outlet of two water pumps is communicated with the circulating hot water import, and the pipeline between two water pumps is communicated with the oxygen-eliminating device water inlet pipe.
Last packing layer is a structured filling material layer with following packing layer.
Water pump is a centrifugal pump.
A kind of exhaust recovery device of deaerator provided by the invention; With the place of packed tower as recovery oxygen-eliminating device discharged steam heat; After in packed tower, injecting the heat of cold desalted water recovery oxygen-eliminating device discharged steam, send packed tower back to after water pump will pressurize from the hot desalted water that packed tower comes out and recycle, send oxygen-eliminating device back to after other has the hot desalted water that reaches temperature standard of few part to be pressurizeed by water pump and use; The oxygen-eliminating device steam consumption is significantly descended, and energy-saving effect is obvious; Also can eliminate the air pollution that produces to atmospheric exhaust because of directly, protect environment; Simple in structure, easy to operate, safe and reliable to operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes packed tower housing 2, the filler in the packed tower housing 2 is divided into packing layer 9 and following packing layer 10; Packed tower housing 2 tops are provided with exhaust outlet 1, and packed tower housing 2 tops are provided with cooling water inlet 3, and packed tower housing 2 bottoms are provided with steam inlet 5 and hot water outlet 6 successively; Circulating hot water import 4 is located on the packed tower housing 2 between packing layer 9 and the following packing layer 10, and outlet conduit 11 1 ends are communicated with hot water outlet 6, outlet conduit 11 other ends respectively with two water pumps 7; 7 ' import is communicated with, and the outlet of two water pumps 7,7 ' is communicated with circulating hot water import 4; Two water pumps 7, the pipeline between 7 ' is communicated with oxygen-eliminating device water inlet pipe 8.
Last packing layer 9 is a structured filling material layer with following packing layer 10.
Water pump 7,7 ' is centrifugal pump.
The course of work of the present invention is following:
In the cooling water inlet 3 on packed tower housing 2 tops, inject cold desalted water; The steam that oxygen-eliminating device is discharged is from bottom that steam inlet 5 is introduced packed tower housings 2; Cold desalted water gets in the packed tower from the cooling water inlet 3 on packed tower housing 2 tops; The Steam Heating that is got in the dropping process of cold desalted water packing layer 9 and following packing layer 10 on process is at last by hot water outlet 6 outflows; Fixed gas enters atmosphere from the exhaust outlet 1 at packed tower housing 2 tops; The hot desalted water that flows out from hot water outlet 6 is through water pump 7; 7 ' pressurization is after circulating hot water import 4 is sent back to the heat that continues to absorb steam in the packed tower housing 2, and the portion of hot desalted water is sent back to oxygen-eliminating device through oxygen-eliminating device water inlet pipe 8 and used.
