Problems solved by technology

During the evaporation process of the heat pipe, it will inevitably carry liquid to the steam end. At the same time, because of the exothermic condensation of the condensation end, there will be liquid in the condensation end, and the liquid will inevitably mix with the steam, so that the fluid in the heat pipe is vapor. Liquid mixture, the existence of vapor-liquid mixture causes the gas to mix together, and the heat exchange capacity between the liquid and the liquid decreases, which greatly affects the heat exchange efficiency
[0007] The existing solar steam generators have low output efficiency and low intelligence, and it is troublesome to realize remote monitoring. Therefore, it is necessary to design a solar steam generator based on intelligent control

Embodiment 1

[0210] As an improvement, a temperature sensor is arranged in the steam drum 3 for measuring the temperature of the steam in the steam drum 3 . The water inlet pipe 8 and the steam outlet 5 of the steam drum 3 are respectively provided with a water inlet valve and a steam valve, and the temperature sensor, the water inlet valve and the steam valve are connected with the central controller 7 for data. The central controller 7 controls the opening and closing and opening of the water inlet valve and the steam valve according to the temperature measured by the temperature sensor.

[0211] If the temperature of the steam in the steam drum 3 measured by the temperature sensor is lower than the lower limit value, the central controller 7 controls the water inlet valve and the steam valve to automatically close, thereby ensuring that the steam in the steam drum 3 continues to heat up; if the measured steam drum If the temperature of the steam in 3 exceeds the upper limit value, then ...

Embodiment 2

[0217] As an improvement, the central controller 7 ensures that the outlet water temperature in the steam drum reaches a constant value by controlling the opening of the water inlet valve and the steam valve. That is, the temperature of the steam at the steam outlet of the steam drum 3 is adjusted by adjusting the said flow rate entering the steam drum 3 and leaving the steam drum 3 .

[0218] An outlet pipe temperature sensor is set on the steam outlet 5 of the steam drum, and the outlet temperature sensor is connected with the data of the central controller 7, and the central controller 7 controls the opening and closing and opening and closing of the water inlet valve and the steam valve according to the temperature measured by the temperature sensor. degree size.

[0219] If the temperature of the steam in the outlet pipe measured by the temperature sensor is lower than the lower limit value, the central controller 7 controls the opening of the steam valve to increase, red...

Embodiment 3

[0226] As a further improvement of the second embodiment, the opening and closing of the steam valve and the water inlet pipe valve are controlled by measuring the temperature of the water in the steam drum 3 .

[0227] If the temperature of the water in the steam drum 3 measured by the temperature sensor 19 is lower than the lower limit value, the central controller 7 controls the opening of the steam valve to increase, and reduces the opening of the water inlet pipe valve, thereby reducing the water entering the steam drum 3 , so that the steam leaving the steam drum 3 increases, thereby reducing the amount of water in the steam drum 3 . The temperature of the water in the steam drum 3 is increased by reducing the amount of water, thereby increasing the outlet temperature of the steam drum 3 . On the contrary, if the temperature of the water in the steam drum 3 measured by the temperature sensor is higher than the upper limit value, then the central controller 7 controls the...

Abstract

The invention provides a solar steam generator, comprising a reflector and a steam drum, the steam drum is located at the focal point of the reflector, and the reflector reflects solar energy to the steam drum for heating the water in the steam drum. A water level gauge is set in the steam drum, and the water level gauge is connected to the data of the central controller. The water inlet pipe and the steam outlet of the steam drum are respectively provided with a water inlet valve and a steam valve, and the water inlet valve and the steam valve are connected with the data of the central controller. Connected, the central controller monitors the height of the water level to control the opening of the steam valve and the water inlet pipe valve. The present invention prevents the water level in the steam drum from being too low by monitoring the height of the water level, thereby causing the heat release end of the heat pipe 3 to fail to dissipate heat and causing damage to the heat pipe. Especially when heated to a boil.

Description

technical field [0001] The invention relates to a steam generator technology, in particular to a steam generator of a heat pipe with a new structure. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe t...
