Description

A solar steam boiler system

technical field

The utility model relates to a solar steam boiler system, which belongs to the technical field of solar energy utilization. the

Background technique

The total solar energy received by the earth every year reaches 1×10 ¹⁸ kW.h, which is equivalent to nearly a thousand times of the proven crude oil reserves on the earth and 3800 times of the world's annual energy consumption in 2000. Therefore, the development and utilization of solar energy has been paid attention to by countries all over the world, and many countries have formulated "sunshine plans" one after another, investing a lot of money and manpower. It is undoubtedly of far-reaching significance to the progress of human civilization to study the collection, conversion, storage and practical application of solar energy from the perspective of science and technology, and to make significant progress.

There are two main ways to use solar energy, one is solar light utilization, which mainly refers to the direct conversion of solar energy into electrical energy by solar cells; the other is solar thermal utilization technology, and the main utilization forms are: solar water heaters, solar refrigeration and air conditioning, Passive solar house, solar thermal power generation, etc. the

Solar thermal utilization can be roughly divided into three forms: low-temperature thermal utilization, medium-temperature thermal utilization and high-temperature thermal utilization. At present, solar thermal utilization is mainly concentrated in the field of low-temperature thermal utilization, and research on solar thermal utilization in the medium-high temperature field is still in its infancy. . the

The use of solar energy to generate hot water or steam is a major form of solar thermal utilization, and solar water heaters are the most common and widely used solar thermal utilization technologies. Solar water heaters can replace coal-fired oil-fired boilers, gas water heaters and electric water heaters to generate domestic hot water, and can also be used for swimming pool heating, aquaculture, greenhouse soil heating, etc. It is estimated that every square meter of solar water heater can save an average of 150kg of standard coal, 450kW.h of electricity and 100kg of carbon dioxide emissions. But what solar water heater provides at present is only the low-temperature hot water of 70～80 ℃, can only satisfy daily life needs. the

Medium and high temperature hot water (steam) is widely used in industry, and can be used for air conditioning, refrigeration, heating, power generation, textile, printing and dyeing, papermaking, rubber, seawater desalination and other production and living fields that require hot water and hot steam. . In the industrial production process of many production and processing fields (petroleum, textile, food), it is necessary to use a large amount of medium and high temperature steam. the

From the perspective of sustainable development of the environment and social economy, it has become an inevitable trend to use solar energy, an environmentally friendly and inexhaustible energy source, to produce medium and high temperature steam. the

Utility model content

The purpose of this utility model is to absorb solar energy through a trough solar collector, heat the water and evaporate it in the fast heating boiler to generate steam, add a water-proof baffle in the fast heating boiler, and prevent the hot water in the fast heating boiler from being carried when it evaporates. Water vapor will increase the moisture content of steam; rely on the steam control valve to adjust the steam supply pressure and steam supply volume, meet the technological requirements of the steam equipment of the enterprise, and realize energy saving and emission reduction. the

The utility model is realized through the following technical solutions: a solar steam boiler system, including a trough solar collector 1, a fast heating boiler 2, a water-proof baffle 6, a circulation pump 7 and a pipeline 8, the fast heating boiler 2 The trough solar collector 1 is connected to the trough solar collector 1 through the circulating pump 7 and the pipeline 8, and the trough solar collector 1 is connected to the fast heating boiler 2 through a countercurrent pipeline, and the fast heating boiler 2 is respectively provided with a steam outlet 9 and a water supply inlet 10 , the interior of the fast heating boiler 2 is provided with a water-proof baffle 6. the

A steam control valve 3 is arranged between the fast heating boiler 2 and the steam outlet 9 . the

A supplementary water pump 5 and a check valve 4 are arranged between the fast heating boiler 2 and the supplementary water inlet 10 . the

When working, the circulating pump 7 transports the water from the fast heating boiler 2 to the trough solar collector 1 for heating through the pipeline 8, and the heated hot water returns to the fast heating boiler 2. Due to the drop in expansion pressure, part of the heat The water flashes to generate steam, and when the steam passes through the water barrier 6, the water carried by the steam will fall into the fast heating boiler 2 due to gravity, so as to prevent the steam from carrying water vapor when the hot water in the fast heating boiler 2 evaporates, causing the steam to contain moisture The amount of steam increases, thereby improving the dryness of the steam. As the amount of steam accumulated in the upper space of the fast heating boiler 2 increases, the pressure in the fast heating boiler 2 increases. When the pressure reaches the opening pressure of the steam control valve 3, the steam control valve 3 When it is turned on, steam is supplied to the steam-consuming equipment to realize the steam supply cycle. After the steam is supplied, the circulating water volume of the system is reduced, and the supplementary water pump 5 is turned on, and the fast heating boiler 2 is supplemented with water through the check valve 4 to realize the supplementary water circulation. the

The utility model has the advantages:

1. Add water baffles in the fast heating boiler to separate the water vapor carried in the steam, improve the dryness of the steam, and thus improve the thermal efficiency of the steam-using equipment;

2. Through the use of trough solar collectors and circulating heating methods, the purpose of using solar energy to generate medium and high temperature steam to supply medium and high temperature steam equipment in enterprises is realized.
