Abstract
Disclosed is a hot water circulating device of a boiler coal economizer. The device relates to the technical field of boiler coal economizers, and comprises a boiler, a boiler water inlet multi-stage pump and the coal economizer; a water inlet end of the boiler is connected with a boiler water inlet pipe; the other end of the boiler water inlet pipe is connected with a water outlet end of the boiler water inlet multi-stage pump; a water inlet end of the boiler water inlet multi-stage pump is connected with a water outlet end of a softening water tank through a water inlet pipe of the boiler water inlet multi-stage pump; the other water outlet end of the softening water tank is further connected with a water inlet pipe of a coal economizer circulating pump; the other end of the water inlet pipe of the coal economizer circulating pump is connected with a water inlet end of the coal economizer circulating pump; a water outlet end of the coal economizer circulating pump is connected with a water inlet pipe of the coal economizer; the other end of the water inlet pipe of the coal economizer is connected with a water inlet end of the coal economizer; a water outlet end of the coal economizer is connected with a backwater pipe of the coal economizer; and the other end of the backwater pipe of the coal economizer is connected with a water outlet end of the softening water tank. The hot water circulating device of the boiler coal economizer utilizes the circulating pump to heat softening water inside the softening water tank via the coal economizer, accordingly heat efficiency of the boiler is greatly improved so as to achieve energy saving and emission reducing effects.
Description
Technical field
The utility model relates to the technical field of boiler economizer.
Background technology
Because boiler economizer, usually all be in boiler feed water, just to bring the hot water in the economizer into boiler, and when stopping into water, the vaporization of will seething with excitement of water in the economizer, produce a large amount of mineral matters be attached to economizer tube wall on have a strong impact on service life of economizer heat-transfer effect and economizer, make the thermal efficiency of boiler reduce.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of hot water circulating device of coal economizer to be provided, and makes that the economizer heat-transfer effect is good, the life-span is long, thereby improves the thermal efficiency of boiler.
The purpose of this utility model is achieved in that hot water circulating device of coal economizer, comprise boiler, boiler feed water multistage pump and economizer, the water inlet end of boiler connects boiler water inlet pipe, the other end of boiler water inlet pipe connects the water side of boiler feed water multistage pump, the water inlet end of boiler feed water multistage pump links to each other by the water side of boiler feed water multistage pump water inlet pipe and softening water tank, another water side of softening water tank also connects economizer circulating pump water inlet pipe, the other end of economizer circulating pump water inlet pipe connects the water inlet end of economizer circulating pump, the water side of economizer circulating pump connects the economizer water inlet pipe, the other end of economizer water inlet pipe connects the water inlet end of economizer, the water side of economizer connects the economizer return pipe, and the other end of economizer return pipe connects the water inlet end of softening water tank.
The beneficial effects of the utility model are: the utility model utilizes the waste heat of boiler smoke that economizer is heated, and utilizes circulating pump that the demineralized water in the softening water tank is heated by the economizer circulation again.In ordinary production, boiler economizer only in boiler feed water, is taken away the hot water in the economizer, as long as the intake pump that stops will can not produce hot water.Novel for addressing the above problem, the pipeline that original multistage pump is connected economizer is removed, directly the outlet pipe of boiler water outlet multistage pump is connected with boiler, water inlet pipe with boiler economizer is connected with the economizer circulating pump again, the outlet pipe of boiler economizer is connected softening water tank, and softening water tank connects the economizer circulating pump by pipeline.Opening the economizer circulating pump makes full use of the economizer temperature demineralized water is heated, remove the oxygen in the demineralized water, minimizing is to the oxygen corrosion of boiler, improve the thermal efficiency of economizer greatly and reduce the deposition of mineral matter, the effectively consumption that reduces the energy service life of raising equipment, thus the thermal efficiency of boiler fully improved.The utility model has the advantages that simple in structurely, rationally, environmental protection energy-conservationly is convenient to operation, thereby the thermal efficiency that improves boiler greatly reaches energy-saving and emission-reduction.
