Water boiler for plateau railway vehicle and control method thereof

Abstract

The invention relates to a water boiler for a plateau railway vehicle. The water boiler comprises a heating tank, a heat exchange tank and a water storage tank which are sequentially arranged from bottom to top, wherein the heating tank is provided with a heating device, the heat exchange tank is connected with the heating tank through a water replenishing pipe with an electromagnetic valve, the top of the heating tank communicates with the interior of the water storage tank through a steam outlet pipe provided with an electromagnetic valve, the heating tank is connected with the water storage box through a water outlet pipe equipped with with an electromagnetic valve and a water pump, the water outlet pipe is partially arranged in the heat exchange box for heat exchange, a steam exhaust pipe is inserted into the water storage tank, the upper end of the steam exhaust pipe is close to the top of the water storage tank and used for exhausting steam, a part of the steam exhaust pipe is arranged in the heat exchange tank and used for heat exchange, and the lower end of the steam exhaust pipe communicates with the atmosphere. According to the invention, a water boiling point can be increased, continuous water supply can be achieved, occupied space is small, and the problems that an electric heating water boiler for a passenger train in a high-altitude area cannot boil water and sterilization is not thorough are solved.

Description

technical field [0001] The invention relates to water supply and drainage technology for plateau railway vehicles, in particular to waterway design for electric water heaters for plateau railway vehicles. Background technique [0002] Chinese people have the habit of drinking hot water. It is generally believed that water can be sterilized during the heating process, and can be used to make tea after boiling. Usually, the boiling point of water is related to the altitude, and the boiling point of water increases with the altitude. However, the data shows that the boiling point of water is 100°C at an altitude of 0m, and only 83°C at an altitude of 5000m. This temperature cannot satisfy the Chinese people's understanding of boiled water. [0003] At present, residents in plateau areas have used pressurization to raise the boiling point of water in their daily lives, such as using a pressure cooker to cook rice. However, the water boilers installed in public places such as rai...

AI Technical Summary

Problems solved by technology

[0003] At present, residents in plateau areas have used pressurization to raise the boiling point of water in their daily lives, such as using a pressure cooker to cook rice. However, the water boilers installed in public places such as railway cars and waiting halls do not use pressurization to raise the boiling point of water, but still use conventional methods. The main reason for the method of boiling water is that the process of pressurized water boiling is as follows: water is injected into the heating container and then sealed and heated—continuous heating until the water boils—stop heating after the set time is reached—the container is depressurized—the container The internal water is drinkable, and the process takes a long time, which can only be used by a small number of people, and there are many people in public places. If it is to meet the needs of many people, a larger airtight container is required, otherwise you have to wait when getting water
