The invention relates to the technical field of chemical equipment, in particular to a steam condensate heat recycling system in a storage and transportation system, which comprises a heat exchanger A, a heat exchanger B, a heat exchanger C and a medium-pressure steam inlet pipe, the medium-pressure steam inlet pipe is communicated with a heating medium inlet of the heat exchanger C, and the heat exchanger C is communicated with a steam return outlet pipe; the steam return outlet pipe is communicated with a low-pressure steam modulation mechanism; the bottom of the heat exchanger C is communicated with a U-shaped condensate water recovery pipe fitting; modulated low-pressure steam output by the low-pressure steam modulation mechanism is communicated with a thermal medium inlet of the heat exchanger A; the bottom of the heat exchanger A communicates with a low-pressure steam condensate pipe; the low-pressure steam condensate pipe is communicated with a low-pressure condensate water collecting box body; and the top of the low-pressure condensate water collecting box body is communicated with the low-pressure steam modulation mechanism. The steam condensate water heat recovery rate is high, the steam condensate water heat recovery device is fully combined with actual production, condensate water heat energy generated by medium-pressure steam is effectively utilized, overall energy consumption is reduced, production cost is saved, and the steam condensate water heat recovery device conforms to the development trend of current green factories.
Description
technical field [0001] The present application relates to the technical field of chemical equipment, and in particular, to a heat recycling system for steam condensed water in a storage and transportation system. Background technique [0002] Whether the structural design of the storage and transportation system in the chemical production design is reasonable is an important factor that determines the energy consumption of the overall production system, and it is also one of the manifestations of the market competitiveness of the prepared products. Usually, the storage and transportation system is connected to the heating equipment used, and the heating equipment of chemical enterprises at this stage is generally connected to the medium-pressure steam pipeline in the industrial park. The medium-pressure steam condenses and releases heat in these heating equipment. The heat energy is transferred to the reaction kettle, and the materials in the reaction kettle are preheated or...
