Energy-saving distilled water machine of gas-fired boiler

Abstract

The invention relates to equipment for preparing distilled water by utilizing waste heat of tail flue gas of a gas-fired boiler, particularly relates to an energy-saving distilled water machine for the gas-fired boiler, and aims to solve the problem that a large amount of heat energy is lost due to the fact that the tail flue gas of the boiler is directly discharged into the atmosphere. Accordingto the equipment, the flue gas direction can be adjusted through a tail flue guide device, and then a distilled water device is turned on or off. When the distilled water device is turned on, flue gaswashes a finned tube below the distilled water device to perform convective heat exchange, and heat is transferred to tap water in the distilled water device to generate steam. The steam rises, encounters cooling water at top, is condensed into distilled water, flows into a distilled water collecting device along a steel plate and then is discharged from an outlet, the tail flue gas guide deviceis provided with a bypass flue which passes through an adjustable baffle, the tap water tank and the cooling water tank enable the water level in the water tank and the water level in the equipment tobe kept consistent through the theory of communicating vessels, a floating ball liquid level switch is arranged on the liquid level, and then automatic water supplementing and automatic condensate water replacing are achieved.

Description

technical field [0001] The patent of the invention relates to equipment for producing distilled water by using the waste heat of flue gas at the tail of a gas boiler, in particular to an energy-saving distilled water machine for a gas boiler. Background technique [0002] Distilled water refers to pure water prepared by distillation, which does not contain impurities. It can not only be used for drinking, but also widely used in scientific fields such as chemistry, biology, and medicine. A distilled water machine is a device for preparing distilled water. The flue gas at the tail of the boiler is directly discharged into the atmosphere, which will cause a large amount of heat loss. Therefore, it is thought of using the waste heat of the flue gas at the tail of the boiler to make distilled water for production and life. Thus the energy-saving distilled water machine was invented. Contents of the invention [0003] Purpose of the invention: The present invention provides ...
