Abstract

The invention discloses a solar boiler soft water preheating system. The solar boiler soft water preheating system comprises a boiler (1), deoxidizing equipment (2), a soft water box (3) and a solar thermal collector (4), and the solar boiler soft water preheating system is characterized in that the solar thermal collector (4) is connected with a heat storing water box (6) through a hot water pipe (5); and the heat storing water box (6) is connected with the solar thermal collector (4) through a water supplying pipe (7) which is provided with a water supplying pump (8), the hot water pipe (5) and the water supplying pipe (7) are respectively provided with a hot water temperature controller (9) and a water supplying temperature controller (10) which are respectively connected with a central control system, the heat storing water box (6) is connected with the soft water box (3) respectively through a water outlet pump (11) and a water supplementary pump (12), and the soft water box (3) is connected with the deoxidizing equipment (2) and the boiler (1) in sequence through a pipeline. The solar boiler soft water preheating system provided by the invention increases the initial temperature of soft water by utilizing renewable solar energy, is energy-saving and emission-reducing, saves non-renewable resources and reduces environmental pollution.

Description

technical field [0001] The present invention relates to the utilization technology of solar energy in the petrochemical industry, in particular to the coupling modification among solar energy efficient heat collection devices, heat storage equipment and industrial boilers, specifically a solar boiler soft water preheating system that provides preheated soft water for boilers . Background technique [0002] In the petrochemical industry, oil products have high viscosity, which is not conducive to long-distance transportation in pipelines. In the industry, the circulating steam heating pipeline is generally installed next to the oil pipeline to heat the oil to reduce the viscosity of the oil. This consumes a lot of energy and emits a lot of carbon dioxide. If 240 tons of steam is used to heat oil products every day, it will consume about 10 tons of coal and emit 2.7 tons of carbon dioxide, and the total annual carbon dioxide emissions will reach about 980 tons. As the main...
