Abstract

The invention discloses a steam waste heat recycling device. The steam waste heat recycling device comprises a boiler, a steam chamber is connected to the boiler through a first connecting pipe, and at least one heat exchanger is arranged in the steam chamber; a hot water storage tank is connected to the steam chamber through a second connecting pipe, and a temperature measuring device is arranged in the hot water storage tank; the hot water storage tank is connected with the heat exchanger through a third connecting pipe, and a first switching valve is arranged on the third connecting pipe; and a steam trap is connected to the bottom of the hot water storage tank through a fourth connecting pipe, and a second switching valve is arranged on the fourth connecting pipe. According to the steam waste heat recycling device, on one hand, the usage amount of boiler fuel is effectively decreased, and industrial water consumption is reduced; on the other hand, the boiler feed water treatment cost is reduced; and in addition, the atmosphere is prevented from being polluted, and the heat efficiency of the boiler is improved.

Description

Technical field [0001] The invention relates to a steam waste heat recovery device. Background technique [0002] As an energy source, steam is widely used in various industries, such as power generation, petroleum, chemical industry, printing and dyeing, papermaking, textile, brewing, rubber, ceramics and other industrial fields. Steam can be used as a heat source, but is actually used It is only the latent heat of steam. [0003] The sensible heat of the steam condensed water (that is, the liquid water formed by the steam through this process) has almost all the heat that is discarded. This is because to improve the production efficiency of steam using equipment, that is, heating efficiency, it is necessary to expel the condensed water with low heat transfer efficiency from the steam as soon as possible. However, the condensed water after work still has a lot of heat. Because the heat of the condensed water cannot be recovered, there are high boiler fuel consumption, large indu...
