The invention provides a waste heat comprehensive utilization device during the production process of fumaric acid, and belongs to waste heat recycling equipment. The waste heat comprehensive utilization device comprises a steam pocket communicated with steam displaced through exothermic reaction in a fumaric acid workshop, a steam header pipe and a steam branch pipe which are connected with other steam application workshops for production of the fumaric acid, wherein, a steam pocket pipe is connected with a steam accumulator; the steam header pipe is connected on the steam accumulator; and the steam accumulator is connected with a lithium bromide refrigerating machine via another pipe. In the invention, by adding the steam accumulator, steam load and heat accumulation can be stabilized; the excessive steam is taken as a driving heat source; the lithium bromide refrigerating machine is used for producing low-temperature circulating cooling water for cooling use in the workshops; and meanwhile steam condensate is recycled so that thermal energy and water resource can be utilized maximally, thus saving energy and production cost.
Description
Technical field
The present invention relates to residual heat recovery equipment, technical field belongs to comprehensive utilizing device for waste heat produced during fumaric acid production.
Background technology
In the fumaric acid production process, the steam that the thermopositive reaction of fumaric acid workshop displaces enters steam manifold and steam branch pipe and enters other each use unit, workshop again after the steam drum collects.Fumaric acid workshop steam production is 20 tons/hour, evenly steam, the total steam consumption fluctuation range in each workshop be the 6-35 ton/hour.Use the vapour characteristics due to the unit, workshop: gap, consumption are unstable, cause the fluctuation of vapor pressure, affect conversely production operation and the control in fumaric acid workshop.When the short period of time, steam consumption was large, in the steam drum, the vapour amount is inadequate, need heat power plant's steam supply, and the most of the time steam consumption is little, and excess steam will be directly emptying from the steam drum by pipeline, cause the waste of heat energy and water resources.
Summary of the invention
The present invention, just in order to overcome above-mentioned deficiency, provides a kind of energy stable with the vapour load, guarantees the stably manufactured in fumaric acid workshop, the comprehensive utilizing device for waste heat produced during fumaric acid production that unnecessary steam waste heat is utilized effectively.Main innovation is to increase a steam accumulator after the steam drum, pipeline access steam manifold again, stablize with vapour load, storage compartment heat energy with steam accumulator, unnecessary steam pipeline connects lithium bromide refrigerator, reaches the purpose of effective comprehensive utilization waste heat.Specifically implement like this: comprehensive utilizing device for waste heat produced during fumaric acid production, comprise with the thermopositive reaction of fumaric acid workshop displace vapor communication the steam drum, produce with fumaric acid steam manifold and the steam branch pipe that other steam is used workshop to be connected, it is characterized in that steam drum pipeline connects a steam accumulator, the steam manifold pipeline is connected on steam accumulator, and the another pipeline of steam accumulator connects lithium bromide refrigerator.
The turnover lithium bromide refrigerator has three groups of pipelines: the steam condensate of lithium bromide refrigerator is connected to the steam system circulation by recovery channel; The cold cycle water coolant of lithium bromide refrigerator (amount is large), respectively used workshop by pipeline communication, and the high temperature circulation water coolant of generation accesses lithium bromide refrigerator again; The inlet/outlet pipe of lithium bromide refrigerator cooling itself water forms circulation (temperature is relatively high, 30 ℃～36 ℃).
The steam that the fumaric acid workshop produces, be introduced into steam accumulator by the steam drum, and play and stablize with the vapour load, the effect of storage compartment heat energy, and then enter other each use unit, workshop through steam manifold and steam branch pipe.Unnecessary steam supply lithium bromide refrigerator is used, and utilizes steam thermal energy for propulsion source, take water as refrigeration agent, take lithium-bromide solution as absorption agent, produces water coolant.According to the surplus of different steam, by regulating the load of lithium bromide refrigerator, balance steam usage quantity, take full advantage of steam.The steam condensate of lithium bromide refrigerator accesses former deionized water system by recovery channel, and steam system is reused.The circulating hot water in workshop, by the lithium bromide refrigerator heat exchange, obtains low-temperature cooling water (7 ℃～12 ℃), improves workshop cooling performance and efficiency.
The present invention loads and accumulation of heat with vapour in order to stable by adding steam accumulator, using excess steam as driving heat source, make the cold cycle water coolant with lithium bromide refrigerator, provide workshop cooling use, improve workshop cooling performance and efficiency, the recovered steam water of condensation, all maximize the use heat energy and water resources simultaneously, saved the energy and production cost.
