Abstract
The utility model discloses a water boiler having influent water preheating device, belonging to the technical field of a boiler design. The utility model is characterized in that an independent influent water preheating device whose upper part and lower part are respectively provided with a water outlet and a water inlet of the preheating device is arranged in a chimney, and the upper part and the lower part of an exchanger inside of the furnace are respectively provided with the water outlet and the water inlet of the exchanger inside of the furnace; further more, the water inlet of the exchanger inside of the furnace is communicated with the water outlet of the preheating device. The hot water boiler adopts the structure arranged in the utility model, the cold water added into the cold water pipeline which enters the preheating device of the chimney firstly exchanges the heat with the high-temperature gas, and the preheated water which enters the exchanger inside the boiler is fully heated. The temperature of the water is raised, the heating time of the water is shortened, the energy is saved; besides, the heat efficiency of the hot water boiler can reach 92%, adopting the heating method.
Description
Technical field
The utility model relates to a kind of heating boiler field, especially relates to a kind of into hot-water boiler of water preheating device that has.
Background technology
Boiler structure on the market is various, but a common principle: and the low temperature backwater of heating installation network is introduced into the heating of boiler furnace high temperature.Flue gas with low temperature heats to high-temperature water again.The utilization rate of the boiler hot of structural principle is low like this, and very big a part of heat has been discharged to atmosphere with flue gas.The utilization rate of the boiler hot on the market is below 78%.
The utility model content
I constantly test through years of researches, have designed successfully to have the into hot-water boiler of water preheating device.Its manufacture craft is simple, and boiler volume is constant, and the thermal efficiency can improve more than 20%, and the cost of the existing boiler that do not raise.This technology can be widely used in various Industrial Boilers, tea furnace, and DEVELOPMENT PROSPECT is very wide.
The utility model provides has into that the technical scheme of the hot-water boiler of water preheating device is:
Have the into hot-water boiler of water preheating device, form by boiler body that heat exchanger in the boiler body is housed and the chimney that heat-exchange device is housed.Its technical characterictic is: heat exchanger and heat-exchange device are relatively independent in the boiler body.The top of heat-exchange device is provided with the delivery port of heat-exchange device, and the below of heat-exchange device is provided with the water inlet of heat-exchange device; The below of heat exchanger is provided with the water inlet of heat exchanger in the boiler body in the boiler body, the top of heat exchanger is provided with the delivery port of heat exchanger in the boiler body in the boiler body, and the delivery port of heat-exchange device is connected with the water inlet of heat exchanger in the boiler body.
Its additional technical feature is: heat-exchange device is the fire-tube type heat dump, and the water inlet of heat-exchange device and the delivery port of heat-exchange device can have water through heat-exchange device.
The utility model provides has into the hot-water boiler of water preheating device and compare with prior art and have the following advantages: the water in the past hot-water boiler is to be introduced into heat exchanger in the boiler, the water that temperature raises carries out temperature exchange with the flue gas that reduces temperature again in the heat-exchange device of chimney, because the temperature difference is less, be unfavorable for the exchange of heat.The hot-water boiler that has water preheating device into adopts low-temperature flue gas preheating water at low temperature, and the water that obtains uniform temperature delivers to that heat exchanger carries out the high temperature heating in the boiler body again.Such mode of heating helps water heat absorption, so the thermal efficiency of boiler improves greatly, and after testing, having into, the hot-water boiler thermal efficiency of water preheating device is 92%.
Description of drawings:
As figure, be wooden utility model provide have an into structural representation of the hot-water boiler of water preheating device.
Among the figure: the delivery port of heat exchanger 3-heat-exchange device in the 1-boiler body 2-boiler body
The water inlet of 4-heat-exchange device 5-heat-exchange device
The delivery port of the water inlet 7-boiler body inner exchanger of heat exchanger in the 6-boiler body
The 8-chimney
The specific embodiment:
When installing and using the hot-water boiler that has water preheating device into, the water inlet 5 of heat-exchange device is connected with the cold water source mouth of pipe, the vessel port that the delivery port 7 of boiler body inner exchanger will be obtained hot water is connected.
During boiler work, the water at low temperature of cold water source pipe enters in the heat-exchange device 4 through the water inlet 5 of heat-exchange device, sufficient temperature exchange takes place with flue gas, the water that temperature raises, enter the inside of heat exchanger 2 in the boiler body by the water inlet 6 of heat exchanger 2 in the delivery port 3 of heat-exchange device 4 and the boiler body, carry out the high temperature heating, the water of rising temperature is discharged outside the boiler through the delivery port 7 of boiler body inner exchanger.
