Problems solved by technology

However, once the heat medium water stops boiling, there will be no heat output almost immediately, resulting in large fluctuations in the temperature of the outgoing water
At the same time, during the working process of the vacuum phase change boiler, it is necessary to frequently start and stop the heating device, which increases the loss of the heating device

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] see figure 1 and figure 2 , the invention discloses a vacuum phase change boiler, which includes a furnace body 1 . The vertical section of the furnace body 1 is gourd-shaped, and the vertical plane cutting the furnace body 1 is perpendicular to the length direction of the furnace body 1 . A base 2 is welded on the bottom of the furnace body 1 . The furnace body 1 is arranged in a sealed manner, and the interior of the furnace body 1 is set in a negative pressure and vacuum environment. An electric heating rod 3 and a heat exchanger 4 are installed inside the furnace body 1 , and heat medium water is also injected in the furnace body 1 . The electric heating rod 3 is located below the heat exchanger 4, and the heat medium water submerges the electric heating rod 3 but does not involve the heat exchanger 4.

Abstract

The invention discloses a vacuum phase change boiler, and relates to the technical field of heating equipment. The vacuum phase change boiler comprises a boiler body and a base arranged on the lower portion of the boiler body in a supporting mode, wherein electric heating rods and a heat exchanger are installed inside the boiler body; the heat exchanger is arranged above the electric heating rods;heat medium water fills the boiler body; the heat medium water submerges the electric heating rods without involving the heat exchanger; the top of the boiler is provided with a vacuum gauge tube joint, a vacuum valve tube seat and a water injection pipe; a water level tube joint is arranged on the side wall of the boiler body; a sewage tube seat is arranged at the bottom end of the boiler body;a plurality of grid plates are arranged inside the boiler body; the grid plates are arranged at the upper portion of the heat exchanger; and the adjacent grid plates are spaced. The vacuum phase change boiler has high condensation speed of water vapor, so that the boiling time of the heat medium water is prolonged, and the outage time of the boiler is shortened.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a vacuum phase change boiler. Background technique [0002] Vacuum phase change boiler is a heating device that uses liquid phase change for heat exchange. The vacuum phase change boiler includes a closed furnace body, and the inside of the furnace body is set as a vacuum environment with negative pressure. The furnace body is filled with heat medium water and installed with a heating device and a heat exchanger. Heat medium water is high-purity water formed by desalination and deoxidation. Utilizing the characteristic of low boiling point of water under low pressure, the heating device heats the heat medium water, so that the heat medium water boils and evaporates to form water vapor. Water vapor condenses on the heat exchanger to form liquid water, and the water vapor releases heat during the process of turning into liquid water, and the released heat will heat the...
