Confined space water vapor continuous generating device

Abstract

The invention belongs to the technical field of chemical experiments, and in particular relates to a continuous steam generation device. The technical scheme of the device for continuously generating water vapor in a confined space is as follows: it comprises: a pressure-resistant water storage device (1), a closed pressure-resistant large tank (11) and a water evaporator ( 5); the pressure-resistant water storage device (1) is located at a high place, and delivers distilled water in the airtight pressure-resistant large tank (11) through the water delivery pipe (4), and the pipeline of the water delivery pipe (4) is provided with a valve (2) and water flow meter (3), and the outlet of the water delivery pipe (4) is facing the groove on the upper surface of the metal casting (7); Trachea (13). The method of the present invention adopts the method of direct heating in a closed space to generate water vapor, the temperature and pressure of the water vapor generated are the same as the environmental conditions of the closed space, and there will be no phenomenon such as secondary condensation.

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.
