Long-service-life steam engine delaying incrustation stacking and application method of long-service-life steam engine

Abstract

The invention relates to a long-service-life steam engine delaying incrustation stacking. The long-service-life steam engine comprises a box and a water level detector. The box is provided with a water inlet, a water outlet and a steam outlet. The box is internally further provided with a heating mechanism and an inner temperature sensor. The lower end of the water level detector is connected with the water outlet through a pipeline, and water path connection is formed between the water level detector and the interior of the box. An upper communication pipe is arranged at the upper end of the water level detector and communicates with the upper portion of the box so that a gas passage can be formed. A water outlet water stop valve is arranged at the end portion of the water outlet, and a water inlet water stop valve is arranged at the end portion of the water inlet. A control mechanism used for controlling the on-off states of the heating mechanism, opening and closing of the water inlet water stop valve and opening and closing of the water outlet water stop valve is further arranged outside the box. The water level detector is provided with a mechanism preventing hot convection and cooling the water level detector. The control mechanism is electrically connected with the inner temperature sensor, the cooling mechanism and the water level detector at the same time. According to the long-service-life steam engine delaying incrustation stacking, the situation that when excessive impurities exist, temperature is increased due to severe boiling of water, and consequently high-temperature damage of the steam engine is caused is effectively prevented, incrustation stacking is delayed, running stability of the steam engine is ensured, and the service life of the steam engine is guaranteed.

Description

technical field [0001] The invention relates to the field of steam engines, in particular to a steam engine with high service life and a method for using the steam engine which delays the accumulation of scale. Background technique [0002] After the water is boiled, part of the water evaporates, and calcium sulfate, which is not easy to dissolve, precipitates. The original dissolved calcium bicarbonate and magnesium bicarbonate decompose in boiling water, release carbon dioxide, and become insoluble calcium carbonate and magnesium hydroxide, which also precipitate, thus forming scale. Boilers that boil water should regularly remove scale, because scale affects heat transfer, too much scale, and may cause boiler explosion due to uneven local heating. [0003] The steam engine is particularly affected by scale during use, because the steam engine needs to heat the water to 95°C-100°C in order to evaporate water better, and the scale will be formed after the water temperature...

AI Technical Summary

Problems solved by technology

Due to the high temperature in the water tank, it provides good conditions for the formation of scale, and the water level detector is easy to be covered with scale, which will affect the accuracy of its detection, cause the malfunction of the controller and cause the operation failure of the machine and dry burning damage

After the water evaporates, it is easy to form sediment in the water tank. The existing steam engine drains water through a simple drain, and it is difficult to remove the sediment well. Over time, it will become scale that is difficult to remove, and too many impurities will cause the space in the water tank to change. Small, boiling water forms foam, which makes the surface temperature of the electric heating tube rise. Long-term high temperature and scale accumulation seriously affect the service life of the steam engine

In addition, the drain valve used is easily damaged due to high temperature, and the scale particles are easy to get stuck and blocked.
