A steam generator with different spacing between upper and lower box vacuum insulation panels

Abstract

The invention provides a steam generator with distances between vacuum insulation panels in an upper box body and a lower box body being different. The steam generator comprises a box body, an electric heating pipe, a cold water inlet and a steam outlet; the box body comprises an inner wall and an outer wall, and the vacuum insulation panels are arranged between the inner wall and the outer wall;the position between the vacuum insulation panels and the inner wall as well as the position between the vacuum insulation panels and the outer wall are filled with a thermal insulation material; thebox body is composed of the upper box body, the lower box body and a vertical box body connected with the upper box body and the lower box body; the distances between the adjacent vacuum insulation panels in the upper box body and the lower box body are different; and the distance between the adjacent vacuum insulation panels in the lower box body is smaller than the distance between the adjacentvacuum insulation panels in the upper box body. According to the steam generator, through the design that the distances between the adjacent vacuum insulation panels in the upper box body and the lower box body are different, the cost of the steam generator can be reduced while the basically identical thermal insulation effect is achieved, or under the same cost condition, the thermal insulation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a steam generator with a new structure. Background technique [0002] A steam generator is a mechanical device that uses heat from fuel or other energy sources to heat water into steam. The steam generator has a wide range of applications, and is widely used in clothing factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories and mines, bean products factories and other places. [0003] Most of the current steam generators are heated by gas or fuel oil, and the heating efficiency is low. Most of the currently used electric steam generators use electric heating tubes installed at the bottom of the water storage tank to directly heat the water in the water storage tank to generate steam. This electric steam generator has the problems of slow heating and low thermal efficiency. [0004] For example, Chinese patent document CN2071061U discloses a st...

Problems solved by technology

[0007] However, the cost requirements of vacuum insulation panels are very high, and the cost requirements of vacuum insulation panels caused by different thicknesses, different thermal conductivity, and the number of vacuum insulation panels used are not high.

The greater the thickness of the vacuum insulation panel, the better the insulation effect, but the cost increases a lot. The lower the thermal conductivity, the better the insulation effect, but the higher the cost, the more the number of vacuum insulation panels distributed, the better the insulation effect, but the cost is also high
