Description

A kind of normal-pressure horizontal carbonated drink heat transfer boiler

The utility model relates to the horizontal boiler of electric heating, fuel oil or combustion gas.

At present, general normal-pressure horizontal boiler comprises cylindrical shell, and the heat exchange device is housed in the inner chamber of cylindrical shell, and as the flue and the heat exchange pipe of electrothermal tube, fuel oil or the gas fired-boiler of boilers heated electrically, cylindrical shell is provided with the effluent pipe mouth and the backwater mouth of pipe that is communicated with cylinder lumen.During use, the thermal energy transfer of heat exchange device is given cold water in the cylinder lumen, makes cold water become hot water, this hot water is entered user's radiator through supply channel by effluent pipe mouth, behind radiator heat-dissipation, get back to cylinder lumen through water return pipeline by the backwater mouth of pipe again, constitute the circulatory system.The drawback of general normal-pressure horizontal boiler is: comprise that 1, the water in the whole circulation system of radiator, water supply line and water return pipeline all successively contacts with the wall of heat exchange device, carry out heat exchange, because the amount of recirculated water is very big, thereby the incrustation scale that forms on heat exchanger wall is just many, the incrustation scale bed thickness, its consequence is that the thermal efficiency of boiler is low, and the heat exchange device is fragile, and service life is short; 2, the water temperature in the cylindrical shell can not be too high, if too high, the stove evaporated quantity of water is big, will add new water in cylindrical shell constantly, and adding of new water forms new incrustation scale on the one hand again on the wall of heat exchange device, make the operating control device complexity of boiler on the other hand; If the water temperature of control cylindrical shell is not too high, directly influence heating effect again.

The purpose of this utility model provides a kind of thermal efficiency height, normal-pressure horizontal carbonated drink heat transfer boiler that heating effect is good.

This normal-pressure horizontal carbonated drink heat transfer boiler, comprise cylindrical shell, the heat exchange device is equipped with in intracavity bottom position at cylindrical shell, what heating medium was housed on cylindrical shell goes out the mouth of pipe and the inlet pipe mouth of pipe, its design feature is that the inner chamber tip position at cylindrical shell is equipped with heat exchange coil, one end of heat exchange coil with go out the mouth of pipe and be communicated with, the other end is communicated with the inlet pipe mouth of pipe, epimere at cylindrical shell is connected with water tank, the end face of water tank is provided with water supplement port and the blow vent that is communicated with water tank cavity, be provided with on the end face of cylindrical shell and pass the overhanging exhaust outlet of water tank, the two sides bottom position that cylindrical shell is positioned at the water tank cavity part is provided with balance pipe.

As the improvement to above-mentioned normal-pressure horizontal carbonated drink heat transfer boiler, balance pipe evenly distributes, and is connected with the vapor barrier sheet of tiltedly stretching to the cylinder lumen top-direction at cylindrical shell corresponding to the lower edge of each balance pipe.

This normal-pressure horizontal carbonated drink heat transfer boiler can be a boilers heated electrically, also can be fuel oil or gas fired-boiler.Be elected to when using boilers heated electrically, the heat exchange device is an electrothermal tube, electrothermal tube is electrically connected with the power supply formation, power supply is contained in the junction box, when selecting fuel oil or gas fired-boiler for use, the heat exchange device comprises flue and smoke pipe, and an end of flue stretches out cylindrical shell, is connected to combustor on it, smoke pipe is communicated with the smoke box inner chamber, and the chimney that is communicated with the smoke box inner chamber is housed on the smoke box.

During use, earlier cylinder lumen and water tank cavity are injected the water of handling through softening, and get rid of the air of cylinder lumen by exhaust outlet, by heat exchange coil, water supply line, inject heating medium in the circulatory system that radiator and water return pipeline constitute, as water through softening processing, connect the power supply or the ignition combustion machine of electrothermal tube again, the heat exchange device temperature raises rapidly, carry out the heat exchange first time with the water in the cylinder lumen, coolant-temperature gage is raise rapidly cause fluidized state, the steam that this fluidized state produces down rises to the top of cylinder lumen, the top that is raised to cylinder lumen waterborne of high temperature, carry out the heat exchange second time with the heat exchange coil that is positioned at the cylinder lumen tip position, give heating medium thermal energy transfer.Because cylindrical shell is provided with the balance pipe with cylinder lumen and water tank cavity connection, when the cold water in the cylindrical shell becomes hot water and steam and causes pressure to increase, just there is a spot of hot water to enter water tank cavity through balance pipe, and water tank cavity is communicated with atmosphere by blow vent, so cylindrical shell and water tank are non-pressure vessel.

From the above mentioned, boiler described in the utility model, because water stops in the water tank cavity, water in the cylinder lumen can be heated to boiling, produce steam, and its evaporation loss also seldom is arranged on the tip position of cylinder lumen again owing to heat exchange coil, and should the zone accumulation regions of high-temperature water and steam just, thereby after the heat exchange second time, the temperature of the heating medium in the heat exchange coil is just high, and heating effect is all right; Also owing to the heating medium in the circulatory system does not directly contact with the heat exchange device, what directly contact with the heat exchange device is demineralized water in the cylinder lumen, thereby the incrustation scale that forms on the heat exchange device wall is just few, the minimizing of incrustation scale, improved the thermal efficiency on the one hand, the heat exchange device is difficult for damaging on the other hand, has prolonged service life.
