The steam required by the industrial production process is generally provided by a small coal or gas fired boiler, so that the energy efficiency is low, the energy consumption is high, the pollution is large, and the desulfurization and denitrification treatment is inconvenient. In recent years, the steam required in the industrial production process is required to be solved by adopting a steam supply mode of power plant centralized industry as far as possible in China and all places.

Since the vast majority of the steam supplied to the industrial process is no longer returned to the power plant. Therefore, the steam-water system of the power plant needs to be supplemented with water, and a water supplementing water source, namely a water treatment system, needs to be newly built or expanded.

The water treatment system of the auxiliary equipment which is usually matched is very large and complex, and the investment ratio is also very large. The reason is that the requirement on the water quality entering the boiler of the power plant is extremely high, and many process links of water treatment are very complicated.

For industrial process steam, in particular steam which is not mixed with industrial materials and is used only for heating, the purity requirement is not very high, which means that the water quality treatment is not very delicate. The water source can be simply prepared by a steam industry enterprise, so that the water treatment system for industrial steam supply is simpler, the investment is reduced, the occupied area is reduced, and the construction period is shortened.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it is to be understood that the description herein is only for purposes of illustration and explanation and is not intended to limit the invention.

As shown in the figure, the industrial steam supply system comprises a steam generator, a heating steam pipeline, a heating steam return pipeline, a heated water supply pipeline, a steam supply pipeline, a superheater, a power plant steam-water system and industrial steam equipment; in the steam generator, high-temperature and high-pressure steam from a power plant is used as a heating source, and introduced water is heated into steam, so that steam supply for external industry is realized. The heated steam from the power plant continues to return to the power plant, and the steam-water system of the power plant does not need to be replenished. The water source for preparing industrial steam supply is simply prepared by a steam industry enterprise.

The steam generator is a tube type steam generator. The inlet of the steam generator tube side is connected with the heating steam pipeline, the outlet of the steam generator tube side is connected with the heating steam return pipeline, and the heating steam return pipeline is connected to a steam water system of a power plant. The inlet of the shell side of the steam generator is connected with a heated water supply pipeline, the outlet of the shell side of the steam generator is connected with a steam supply and discharge pipeline, and the steam supply and discharge pipeline is connected with a superheater and then supplies steam to industrial steam equipment. The steam generator may be either vertical or horizontal.
