The novel energy saver for boilers mainly comprises a barrel body with a lifting lug, wherein a flue gas device is arranged above the barrel body; a bottom seat is fixed under the barrel body; a gas passage pipe is arranged inside the barrel body; a thermal insulation layer is arranged on the inner wall of the barrel body; a water level gauge A and a water level gauge B are arranged on the outer wall of the barrel body; the bottom of the gas passage pipe is higher than the top of a flue gas pipe; the flue gas device is divided into a flue gas inlet pipe and a flue gas outlet pipe through a partition plate; pipe plates are arranged at the top and the bottom of the flue gas pipe; the pipe plates are connected with the barrel body, the flue gas pipe and the partition plate in a sealing manner; a water inlet pipe and a water outlet pipe are arranged vertically on the barrel body close to the pipe plates respectively; and an ash removing outlet and a sewage draining pipe are arranged on the barrel body under the flue gas pipe. The novel energy saver for boilers is mainly suitable for the vertical coal-fired steam boiler.

Description

The New-type boiler energy-saving appliance

Technical field

The utility model relates to a kind of New-type boiler energy-saving appliance, and it belongs to the pressure vessel technology field.

Background technology

The vertical fire coal steam boiler, by shell, end socket, flue; The flue top, U type circle, compositions such as impact tube; Combustion chamber placement is divided into two combustion chambers up and down with the refractory concrete chimney arch with burner hearth in flue, the flue gas that the bottom burning produces fully burning after the aditus laryngis on the refractory concrete chimney arch gets into secondary combustion chamber and the secondary wind of upper furnace door input is mixed; The high-temperature flue gas that is produced carries out heat convection through annular smoke box, after chimney enters atmosphere once more behind the furnace heating surface radiation heat transfer.In the direct discharged air of flue gas, mean that the part of fuel input heat is taken away by flue gas, scatter and disappear in atmosphere, not only cause flue gas loss easily, and also can cause thermal pollution atmosphere.

The utility model content

There is the deficiency of flue gas loss, contaminated environment in the utility model to vertical coal-fired steam boiler in the prior art, and a kind of New-type boiler energy-saving appliance that is applied to boiler is provided.

The technical scheme that the utility model solves the problems of the technologies described above is following:

A kind of New-type boiler energy-saving appliance comprises the cylindrical shell that has hanger, and the top of said cylindrical shell is provided with flue gas device, and the below is fixed with base, and inside is provided with breather pipe, and the bottom of said breather pipe is higher than the top of smoke pipe; Said flue gas device is divided into smoke-intake pipe and pipe through dividing plate; Said barrel is evenly equipped with smoke pipe, and the top and the bottom of said smoke pipe are equipped with tube sheet, and said tube sheet and cylindrical shell, smoke pipe and dividing plate all are tightly connected; Be respectively equipped with water inlet pipe and outlet pipe up and down near the tube sheet place on the said cylindrical shell.

Compared with prior art, the beneficial effect of the utility model is: can make full use of back-end surfaces and absorb heat, reduce exhaust gas temperature, alleviate the thermal pollution of flue gas to atmosphere; Increase the flow process of washing away of flue gas, improved convection transfer rate.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, the cylindrical shell below the said smoke pipe is provided with ash disposal mouth and blow-off pipe.

Adopt the beneficial effect of above-mentioned further scheme to be: the design of ash disposal mouth, make the staff can in time clear up inner cigarette ash, reached environmental requirement, greatly reduce pollution to atmosphere.

Further, outer water level meter first and the water level meter second of being provided with of said cylindrical shell.

Adopt the beneficial effect of above-mentioned further scheme to be: the handled easily personnel can confirm the height of water level in the cylindrical shell at any time.

Further, said cylinder inboard wall is provided with heat-insulation layer.

Adopt the beneficial effect of above-mentioned further scheme to be: the setting of heat-insulation layer, make barrel radiation reduce, further improved absorption to flue gas heat.
