Abstract

The invention belongs to the technical field of chemical experiments and relates to a device for generating vapor continuously, in particular to a device for generating vapor continuously in a closed space. According to the technical scheme, the device comprises a pressure-proof water storage device (1), a large closed pressure-proof tank (11) and a water evaporator (5) installed in the large closed pressure-proof tank (11); the pressure-proof water storage device (1) is located at a high position and delivers distilled water into the closed large closed pressure-proof tank (11) through a water delivery pipe (4), a valve (2) and a water flowmeter (3) are arranged on a pipeline of the water delivery pipe (4), and an outlet of the water delivery pipe (4) faces directly a groove in the upper surface of a metal casting body (7); a breather pipe (13) is arranged between the pressure-proof water storage device (1) and the closed large closed pressure-proof tank (11). According to the device, the vapor is generated through the method that heating is conducted directly in the closed space, the temperature and pressure for generation of the vapor are the same as the environmental condition of the closed space, and the phenomena such as secondary condensation are not caused.

Description

technical field [0001] The invention belongs to the technical field of chemical experiments, and in particular relates to a continuous steam generation device. Background technique [0002] Many scientific research projects and industrial reaction processes require continuous and stable supply of water vapor in a confined space in the preliminary tests, and can be measured in real time, especially in some small-scale experimental studies where water vapor participates in reactions, the amount of water vapor required is relatively large At the same time, there is a requirement for a stable supply of water vapor and online control, which puts forward higher requirements for the water vapor generating device. However, some test environments are more complicated, such as high temperature and high pressure or the required test gas contains flammable and explosive gases such as hydrogen, and the water vapor generator needs to meet these strict requirements.

Problems solved by technology

However, some test environments are more complicated, such as high temperature and high pressure or the required test gas contains flammable and explosive gases such as hydrogen, and the water vapor generator needs to meet these strict requirements

[0003] At present, there are many ways to produce water vapor in the laboratory, such as using a high-temperature and high-pressure steam generator for water vapor input, but the small high-temperature and high-pressure steam generator has a complex structure, is expensive, and has a large pressure change , can not operate with steady pressure, so the water vapor flow is basically uncontrollable

Although the use of large-scale steam boilers can stabilize the flow of water vapor, the equipment is bulky and expensive, and the water vapor transportation process is far away. Condensed water is likely to be generated during the transportation, which is not conducive to the measurement of water vapor and cannot meet the needs of the laboratory.
