Abstract
The utility model relates to a production device for producing epoxypropane by using pre-heated process water through chlorohydrination, belonging to the field of chemical production equipment. The production device is characterized by comprising an industrial waste water pool, a circulating pump, a heat exchanger, a sewage treatment device, a process water pool and an epoxypropane reactor, wherein the industrial waste water pool is connected with the circulating pump by a pipeline; the circulating pump is connected with a tube-side inlet of the heat exchanger; a tube-side outlet of the heat exchanger is connected with the sewage treatment device by a pipeline; the process water pool is connected with the tube-side inlet of the heat exchanger; and the tube-side outlet of the heat exchanger is connected with the epoxypropane reactor by a pipeline. Heat exchange of industrial waste water and the process water is carried out in the heat exchanger, so that heat is acquired by the process water as the cold medium; the temperature of the process water is improved; and the production cost is saved. Meanwhile, the loss of the heat energy of the industrial waste water is avoided; and the energy is saved. Besides, the production device is stable to operate, convenient to operate, and convenient to maintain.
Description
Technical field
The utility model relates to a kind of production equipment of producing epoxypropane by chlorohydrination of pre-heating technique water, belongs to the chemical production equipment field.
Background technology
Steam is as one of main energy sources of producing expoxy propane, and it is larger to account for cost proportion, and the technique water temperature is most important to steam mono-consumption, temperature when fresh water (FW) enters is higher, the quantity of steam that consumes is just fewer, however the supernatant that in this reaction, obtains (about about 80 degree of temperature, amount 650t h), as sewage, directly enter sewage disposal device, carry out biochemical treatment, its heat energy wastes, like this and be unfavorable for the recycling of the energy, caused on the contrary the waste of the energy.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: a kind of production equipment of producing epoxypropane by chlorohydrination of pre-heating technique water is provided, utilizes wastewater temperature to improve the temperature of industry water, reduce cost, energy savings.
The technical scheme that its technical problem that solves the utility model adopts is: the production equipment that a kind of producing epoxypropane by chlorohydrination of pre-heating technique water is provided, it is characterized in that comprising: the Industry Waste pond, circulating pump, heat exchanger, sewage disposal device, process water pond and propylene oxide reaction device, the Industry Waste pond connects circulating pump by pipeline, circulating pump connects the heat exchanger tube pass entrance by pipeline, connect the heat exchanger tube pass outlet and connect sewage disposal device by pipeline, process water pond connects the heat exchanger shell pass entrance by pipeline, and the heat exchanger shell pass outlet is by pipeline connecting ring Ethylene Oxide reactor.
During use, industrial wastewater is recycled from the Industry Waste pond and is pumped into heat exchanger, fresh water (FW) also enters heat exchanger by process water pond simultaneously, in heat exchanger, carry out heat exchange, fresh water (FW) has just obtained heat as cold medium like this, has improved self temperature, has reduced fresh water (FW) and has entered required quantity of steam behind the propylene oxide reaction device, industrial wastewater is transported to sewage disposal device simultaneously, carries out biochemical treatment.
The beneficial effects of the utility model are: carry out heat exchange by industrial wastewater and fresh water (FW) in heat exchanger, fresh water (FW) has just obtained heat as cold medium like this, improved self temperature, saved production cost, avoided simultaneously the loss of the heat energy of industrial wastewater, saved the energy, in addition this stable equipment operation, easy to operate, be convenient to care and maintenance.
