Embodiment Construction

[0052] Figure 1-5 A steam generator is shown. Such as figure 1As shown, the steam generator includes a box body 1, an inner pipe body 2, a cold water inlet 3, a hot water outlet 4 and a steam outlet 5, the cold water inlet 3 is arranged at the lower part of the box body 1, and the hot water outlet 4 Located on the top of the box body. The inner tube body 2 is arranged in the box, and the inner tube body 2 is arranged in a vertical direction (perpendicular to the bottom plane of the water tank), and the inner tube body 2 includes an outer tube and a core body 7 arranged in the outer tube. The lower part of the pipe body 2 is provided with a water inlet passage 8 to ensure that the water in the box body 1 can enter the inner pipe body 2 for heating, and the upper part of the inner pipe body 2 is connected to the steam outlet 5; the core body 7 is arranged on the upper part of the water inlet passage 8, so that The core body 7 extends in the vertical direction of the inner tu...

Abstract

The invention provides a design method for a steam generator with the varying areas of water inlet channels. The steam generator comprises a box body and an inner pipe body. The inner pipe body comprises an outer pipe and a core body arranged in the outer pipe. The core body is composed of a square through hole and a regular octagonal through hole. The side length of the square through hole is equal to the edge length of the regular octagonal through hole. The four sides of the square through hole are four different edges of the regular octagonal through hole correspondingly, and the four sides, arranged at intervals, of the regular octagonal through hole are four different edges of the square through hole correspondingly. An electric heater is arranged in the square through hole. The steam generator is designed by the following method: the multiple rows of the water inlet channels are arranged in the height direction; and the distribution densities of the water inlet channels are smaller and smaller in the height direction. By the adoption of the design method for the steam generator of the novel structure, the dry-up problem of the inner pipe body is reduced, and meanwhile the heating efficiency is improved.

Description

[0001] This application is a divisional application for November 28, 2018, application number 2018114332903, and the title of the invention "a steam generator design method with variable spacing between water inlet holes". technical field [0002] The invention relates to the technical field of boilers, in particular to a steam generator with a new structure. Background technique [0003] 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. [0004] 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...
