Description

High-efficiency non-storage boiler steam generator

Technical field

The utility model belongs to the field of steam cleaning appliances, in particular to a high-efficiency boiler steam generator without water storage.

Background technique

A steam generator (commonly known as a boiler) is a mechanical device that uses fuel or other energy to heat water into hot water or steam. Its working principle is that the boiler uses the circulating flow of water during operation to continuously remove all the heat absorbed by the heated surface, so that the water is heated and gasified into steam.

According to a utility model provided by our country named Electric Steam Boiler, the application number is 201820420452.9, and the authorization number is CN.208058802.U. We learned that the electric steam boiler in this utility model includes electric heating cavity and electric heating cavity The water supply end and the steam output end are connected. The water supply end is provided with a water supply tank and a pressure pump. The water supply tank is the same as the electric heating chamber through the pressure pump.

The metal water pipe is spirally wound on the outer peripheral wall of the metal liner. Several U-shaped metal heating pipes are evenly distributed around the metal liner circumferentially and are There is a gap between each of the U-shaped metal heating pipes and the metal water pipe. The shell is made of aluminum casting and is filled with the gap.

Its working principle is: the metal heating tube is electrically and thermally conductive, and the metal water pipe and the boiler liner are heated at high temperature to form a high temperature and high pressure environment inside. When the peripheral water pump injects a certain pressure of water into the metal water pipe, the role of high temperature The water is instantly vaporized into water vapor. The vaporized water vapor spirally flows in a spiral metal water pipe and enters the boiler liner at a higher pressure under the effect of negative pressure in the pipe; after the first vaporization is completed The steam is reheated in the boiler liner with the same high pressure and high temperature to vaporize the steam water left by the first steam again. During the vaporization process, the boiler liner has water molecules in the high temperature and high pressure environment. More sufficient energy to overcome the strong force of hydrogen bonds, so that the unbroken hydrogen bonds in the water molecules are broken, and more fully vaporized water vapor is obtained to achieve the effect of generating more steam with a smaller amount of water. The conversion rate of steam is improved; at the same time, there is no water stored in the boiler liner, only a certain pressure needs to be controlled by the external water pump, the steam in the boiler will not generate excessively high air pressure, nor will it explode due to excessively high air pressure , Which improves safety. When water is not injected into the boiler cavity, the boiler liner will automatically maintain heat when it reaches a certain temperature, which improves the heat conversion efficiency, and does not require power consumption, and the boiler cavity will not produce dry burning. Played the effect of energy saving.

In the above-mentioned high-efficiency waterless boiler steam generator, the several U-shaped metal heating tubes are equally divided into three groups evenly distributed outside the metal liner, and each group of U-shaped metal heating tubes contains two or two More than one U-shaped metal heating tube, each group of U-shaped heating tubes is arranged parallel or obliquely on the metal liner.

In the above-mentioned high-efficiency non-storage boiler steam generator, an air outlet connector is installed on the second air outlet, and the inner end of the air outlet connector extends into the metal liner.

In the above-mentioned high-efficiency waterless boiler steam generator, a metal seal ring is provided between the gas outlet joint and the second gas outlet.

In the above-mentioned high-efficiency waterless boiler steam generator, the bottom of the casing is provided with a cleaning port and the cleaning port is sealed by a plug, and the inner end of the plug extends into the metal liner.

In the above-mentioned high-efficiency non-storage boiler steam generator, the shape of the metal liner may be a cylinder, a rectangular parallelepiped, or an elliptical cylinder.
