High-efficient steam generator based on disturbance in tube

Abstract

The invention discloses a high-efficient steam generator based on disturbance in a tube. The high-efficient steam generator comprises an evaporating pipe, a heating body and a heat preservation unit,wherein a water inlet and an air outlet are formed in the evaporating pipe, and the heating body is used for heating the evaporating pipe. The evaporating pipe is internally provided with disturbancecomponents which are distributed in the length direction and partly block flow in the radial direction. According to the high-efficient steam generator based on disturbance in the tube, the disturbance components are inserted into a wound tube, the disturbance of water in a flowing process is increased, so that heat exchange is significantly enhanced, the degree of superheat of a steam outlet is improved, and the thermal efficiency is significantly improved; and the generator is small in overall size, light in weight, simple in structure, and relatively low in cost, so that wider application can be realized.

Description

technical field [0001] The invention relates to the technical field of steam generation, in particular to a high-efficiency steam generator based on disturbance in a pipe. Background technique [0002] The steam generator is an important component of steam equipment and is widely used in household appliances, such as steam irons and steam microwave ovens. In addition, steam generators also play a huge role in the cleaning of household appliances, such as range hoods. During the use of the range hood, a large amount of oil will accumulate on the surface of the impeller and filter screen. Oil stains are easy to condense and difficult to clean, which increases the burden on the range hood and affects the oil absorption efficiency. At the same time, the inner wall of the volute will become rough due to the adsorption of oil, which will affect the optimized exhaust surface of the volute and increase the noise of the range hood. [0003] In order to solve this problem, research...

Problems solved by technology

For example, CN101749774A discloses a range hood with electric heating, which uses electric heating wires to bake oil stains to make them drip, but the location of electric heating is limited, resulting in blind spots in oil removal, which cannot be cleaned thoroughly

Therefore, research and development personnel have developed some steam generators for cleaning household appliances, such as CN201652552U discloses an automatic cleaning device, which uses steam and hot water as a medium to clean oil stains. In order to achieve the effect of automatic cleaning, the invention adds spray guns, Water pumps and control components greatly increase the cost of production, and the steam and hot water used may not be able to achieve a good cleaning effect due to insufficient temperature

At the same time, due to the fouling problem of the steam generator during use, it will block the pipeline in severe cases and affect the performance
