Abstract
The utility model relates to a comprehensive utilizing device for waste heat produced during fumaric acid production, which adopts fumaric acid recycling equipment, and comprises a steam dome communicated with the steam displaced through the exothermic reaction of fumaric acid workshop, as well as a steam main pipeline and steam branches connected with other steam utilization workshops for producing fumaric acid, wherein the steam dome pipeline is connected with a steam heat accumulator, the steam main pipeline is connected onto the steam heat accumulator, and another pipeline of the steam heat accumulator is connected with a lithium bromide refrigerating machine; and the steam heat accumulator is additionally arranged to stabilize steam utilization load and heat accumulation, the surplus steam is adopted to drive heat source, and the lithium bromide refrigerating machine is adopted to produce low temperature cycle cooling water, so as to provide the cooling function for the workshop and recycle steam condensed water at the same time. Therefore, both the heat energy and water source can be utilized to the maximum degree, and the energy and production cost are saved.
Description
Technical field
The utility model relates to residual heat recovery equipment, and technical field belongs to fumaric acid production process residual heat integrative use device.
Background technology
In the fumaric acid production process, the steam that the exothermic reaction of fumaric acid workshop displaces enters main steam range and steam branch pipe and enters other each use unit, workshop again after the steam drum compiles.Fumaric acid workshop steam production is 20 tons/hour, evenly steams, and the total steam consumption fluctuation range in each workshop is 6～35 tons/hour.Since the unit, workshop use the vapour characteristics: gap, consumption instability, cause the fluctuation of steam pressure, influence the production operation and the control in fumaric acid workshop conversely.When the short time, steam consumption was big, the vapour amount was not enough in the steam drum, need steam power plant's steam supply, and the most of the time steam consumption is little, excess steam will be directly by pipeline from the emptying of steam drum, cause the waste of heat energy and water resource.
Summary of the invention
The utility model provides a kind of energy stable with the vapour load just in order to overcome above-mentioned deficiency, guarantees the steady production in fumaric acid workshop, the fumaric acid production process residual heat integrative use device that unnecessary steam waste heat is utilized effectively.Main innovation is to increase a steam accumulator behind the steam drum, pipeline inserts main steam range again, stablizes with vapour load, storage compartment heat energy with steam accumulator, unnecessary steam then pipeline connects lithium bromide refrigerator, reaches the purpose of effective comprehensive utilization waste heat.Specifically implement like this: fumaric acid production process residual heat integrative use device, comprise with the exothermic reaction of fumaric acid workshop displace vapor communication the steam drum, produce main steam range and the steam branch pipe that other steam uses workshop to be connected with fumaric acid, it is characterized in that steam drum pipeline connects a steam accumulator, the main steam range pipeline is connected on the steam accumulator, and steam accumulator pipeline in addition connects lithium bromide refrigerator.
The turnover lithium bromide refrigerator has three groups of pipelines: the steam condensate (SC) of lithium bromide refrigerator is connected to the vapour system circulation by recovery channel; The low temperature recirculated cooling water of lithium bromide refrigerator (amount is big) respectively uses the workshop by the pipeline connection, and the high temperature circulation cooling water of generation inserts lithium bromide refrigerator again; The turnover pipe of lithium bromide refrigerator self cooling water constitutes circulation (temperature is higher relatively, 30 ℃～36 ℃).
The steam that the fumaric acid workshop produces is introduced into steam accumulator by the steam drum, play stable with the vapour load, the effect of storage compartment heat energy, and then enter other each workshop through main steam range and steam branch pipe and use unit.Unnecessary steam supply lithium bromide refrigerator uses, and utilizes steam thermal energy to be power source, is cold-producing medium with water, is absorbent with the lithium-bromide solution, produces cooling water.According to the surplus of different steam, by regulating the load of lithium bromide refrigerator, balance steam use amount makes full use of steam.The steam condensate (SC) of lithium bromide refrigerator inserts former deionized water system by recovery channel, reuses for vapour system.The circulating hot water in workshop obtains low-temperature cooling water (7 ℃～12 ℃) by the lithium bromide refrigerator heat exchange, improves workshop cooling effect and efficient.
The utility model is loaded and accumulation of heat with vapour in order to stable by adding steam accumulator, excess steam as driving heat source, make the low temperature recirculated cooling water with lithium bromide refrigerator, provide the workshop cooling to use, improve workshop cooling effect and efficient, the recovered steam condensed water all maximizes the use heat energy and water resource simultaneously, has saved the energy and production cost.

Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Fumaric acid production process residual heat integrative use device, comprise with the exothermic reaction of fumaric acid workshop displace vapor communication the steam drum, produce main steam range and the steam branch pipe that other steam uses workshop to be connected with fumaric acid, steam drum pipeline connects a steam accumulator, the main steam range pipeline is connected on the steam accumulator, and steam accumulator pipeline in addition connects lithium bromide refrigerator.
The turnover lithium bromide refrigerator has three groups of pipelines: the steam condensate (SC) of lithium bromide refrigerator is connected to the vapour system circulation by recovery channel; The low temperature recirculated cooling water of lithium bromide refrigerator respectively uses the workshop by the pipeline connection, and the high temperature circulation cooling water of generation inserts lithium bromide refrigerator again; The turnover pipe of lithium bromide refrigerator self cooling water constitutes circulation.
After this device comes into operation, about 25000 tons of year recovered steam, 25000 tons of recovered steam condensed waters reduce full company production cost 3%～6%.
