Abstract

The utility model discloses a recycling system for low-grade steam heat energy of a deaerator. The recycling system comprises a thermal deaerator, a mixer, a desalting water pipe and a draining tank and is characterized in that an air steam discharge pipe is arranged on the thermal deaerator; the air steam discharge pipe is connected with the mixer through a pipeline; the mixer is connected with the desalting water pipe through the pipeline; the air steam discharge pipe is arranged above the mixer; the draining tank is connected with the mixer and the water tank of the thermal deaerator through the pipeline. According to the utility model, the recycling for the low-grade steam heat energy of the thermal deaerator is realized; the steam consumption of a power plant is reduced; the production cost is lowered; the noise pollution and the moisture pollution of air steam discharge are eliminated; the national energy-saving and emission-reducing policy is met; the economic benefit and the environmental protection benefit are obvious.

Description

The recycling system of the low-grade steam thermal energy of a kind of oxygen-eliminating device
Technical field
The utility model relates to power industry and heating industry field of industrial production, is specifically related to the recycling system of the low-grade steam thermal energy of a kind of oxygen-eliminating device.
Background technology
Boiler is electric power, key equipment in heat supply production, in order to stop the oxygen corrosion of boiler plant heating surface, guarantee the safe operation of boiler, it is a requisite important procedure that boiler feedwater is carried out to deoxygenation, thermal deaerator is exactly the heat power equipment that carries out boiler supply water deaerating, thermal deaerator produces the low-grade steam that carries a large amount of oxygen and discharges to sky in running, cause thermal waste, the domestic process that this part steam thermal energy is recycled is a lot of at present, main jet pump negative-pressure adsorption and two kinds of technology of hybrid separation of adopting, affect deaerating effect but all exist, varying duty ability, system complex, operation requirements is high, the defect of the high different one-tenth degree of investment operating cost.
Utility model content
For solving the problems of the technologies described above, the utility model provides the recycling system of the low-grade steam thermal energy of a kind of oxygen-eliminating device.
The technical solution used in the present invention is as follows:
The recycling system of the low-grade steam thermal energy of a kind of oxygen-eliminating device, comprise thermal deaerator, blender, desalination jellyfish pipe, drain tank, it is characterized in that, described thermal deaerator is provided with empty gland steam exhauster, described empty gland steam exhauster is connected with blender by pipeline, described blender is connected with desalination jellyfish pipe by pipeline, and described blender top is provided with empty blast pipe, and described drain tank is connected with the water tank of blender and thermal deaerator by pipeline.
On described blender, be provided with detection alarm device.
On described pipeline, be equipped with valve.
The low-grade steam of the thermal deaerator in the utility model enters blender by pipeline, valve, enter blender from the normal temperature desalted water of Desalting Water System by cold water pipe simultaneously, mix with the low-grade steam from thermal deaerator, demineralized water is heated to 80 DEG C of left and right, the highest 90 DEG C.In blender, carry out degassed deoxygenation, the on-condensible gases such as the oxygen of separation are from normal pressure delivery pipe directly discharged to atmosphere simultaneously, and hot water enters in drain tank, and the heat energy of low-grade steam and condensate water are all reclaimed.
The beneficial effects of the utility model:
The utility model has been realized the recycling of the low-grade steam thermal energy of thermal deaerator, reduce power plant's steam consumption, reduced production cost, eliminated noise pollution and the moisture contamination of air-out tube, meet national energy-saving and emission-reduction policy, there is significant economic benefit and environmental benefit.
