Description

The boiler hot interchanger

Technical field

The utility model relates to a kind of heat-exchange device, particularly a kind of boiler hot switch.

Background technology

At present, the utilization again of the useless flue gas of boiler and workshop reactor distillation water reuse are the important means that the fuel consumption is reduced, existing Industrial Boiler relatively is short of aspect the utilizing of flue gas and steam, generally be by the give up utilization again of flue gas of economizer, and the distilled water that the workshop reactor produces is just directly discharged, and is not effectively utilized.

Summary of the invention

The purpose of this utility model is to provide a kind of and not only can reclaims useless flue gas but also can reclaim distilled water, and reduces the boiler hot interchanger of fuel consumption.

In order to achieve the above object, the technical solution of the utility model is:

A kind of boiler hot interchanger, comprise housing and first, second end cap, housing and first, second end cap seal connects, the inside of described housing be provided with inner walls be tightly connected first, second partition, form first inner chamber between first dividing plate and first end cap, form second inner chamber between the second partition and second end cap, be connected one group of tubulation that is used for heat exchange between first dividing plate and the second partition, and between inner walls between first dividing plate and the second partition and tubulation outer wall, forming heat exchange chamber, tubulation is communicated with first inner chamber and heat exchange chamber and first inner chamber and second inner chamber is separated with second inner chamber; The sidewall of described housing has distilled water collecting pipe and the soft water collecting pipe that is communicated with heat exchange chamber, and the sidewall of housing also has the adjutage that is communicated with heat exchange chamber; Have smoke intaking hole on described first end cap, have exhaust smoke hole on second end cap.

Described first end cap comprises conical shell, square upper flange and square lower flange.

Described second end cap comprises conical shell, square upper flange and square lower flange.

Described housing is a square cylinder, and the both ends of the surface of housing all have square flange, and fixedlys connected with the square lower flange of first end cap and the square lower flange of second end cap.

The outer wall of described housing, distilled water collecting pipe, soft water collecting pipe and adjutage all is enclosed with insulation material.

After the utility model adopts said structure, because the inside of housing is provided with first, second dividing plate that is tightly connected with inner walls, form first inner chamber between first dividing plate and first end cap, form second inner chamber between the second partition and second end cap, be connected one group of tubulation that is used for heat exchange between first dividing plate and the second partition, and between inner walls between first dividing plate and the second partition and tubulation outer wall, forming heat exchange chamber, tubulation is communicated with first inner chamber and heat exchange chamber and first inner chamber and second inner chamber is separated with second inner chamber; The sidewall of described housing has distilled water collecting pipe and the soft water collecting pipe that is communicated with heat exchange chamber, the sidewall of housing also has the adjutage that is communicated with heat exchange chamber, therefore the distilled water that flows out from reactor flows into the heat exchange chamber of boiler hot interchanger by the distilled water collecting pipe, the soft water that flows out from the soft water interchanger also enters the heat exchange chamber of boiler hot interchanger by the soft water collecting pipe simultaneously, again owing to have smoke intaking hole on first end cap of the present utility model, has exhaust smoke hole on second end cap, therefore useless flue gas enters first inner chamber of housing by the smoke intaking hole of end cap, this moment is owing to be connected one group of tubulation that is used for heat exchange between a dividing plate and the second partition, and between inner walls between first dividing plate and the second partition and tubulation outer wall, form heat exchange chamber, therefore flue gas enters the tubulation in the housing heat exchange chamber, soft water in the heat hot inverting chamber once more, therefore not only can reclaim useless flue gas but also can reclaim distilled water, because the sidewall at housing also has the adjutage that is communicated with heat exchange chamber, therefore pass through water pump then, the soft water that heats is restored to economizer and enters in the boiler, circulation successively reaches the effect that reduces the fuel consumption.
