Abstract

The invention discloses a vapor condensing and recovering device for use in production of polyester and belongs to the technical field of chemistry and mechanics. According to the vapor condensing and recovering device, the condensed water return water pipes of a vapor heating and heat tracing system are communicated with a vapor condensing water tank; and an upper set of nozzle and a lower set of nozzle are arranged in each condensed water return water pipe. The water inlet pipe of a multi-stage pump is led out from the lower part of a water tank. One path of the water outlet pipe of the multi-stage pump is communicated with a vapor generator and the other path of the water outlet pipe of the multi-stage pump is communicated with the nozzles of the condensed water return water pipe. The vapor condensing and recovering device is used to collect and recover 90 percent of the vapor sprayed by the multi-stage pump in a self-circular manner from the condensed water return water pipe, thereby circularly using the condensed water, reducing consumption of primary soft water and saving 60 cubic meters of water daily. As the heat of the vapor in the vapor condensing water tank is collected, the temperature of the water rises to about 80 DEG C from the original 50 DEG C, the water is conveyed to a vapor generator to be used circularly, the heat energy is comprehensively used, and the energy consumption is saved.

Description

Vapour-condensing equipment for recovering in the production of polyester
Technical field: the present invention relates to the device for recovering tail gas in a kind of chemical plant production, belong to chemical machinery field.
Background technology: many materials are arranged for being prone to coagulated substance during polyester (PBT) is produced, for preventing process line by material obstructions of condensing, in the equipment in a large number pipelines used the water vapour of different pressures to accompany heat.The steam of three strands of different pressures converges at three main pipe lines behind drain valve, get into condensation water tank.Get into behind the condensation water tank in the steam water interface a large amount of steam and be not condensed and collect and be directly emitted, cause the loss of the water yield and heat.Keep the normal liquid level of vapour generator, just need continuous supplementation soft water.The direct discharging of this uncondensated steam causes the waste in about 20,000 sides water/year, also causes a large amount of energy dissipations simultaneously.
Summary of the invention: the objective of the invention is to design the vapour-condensing equipment for recovering in a kind of production of polyester, get up the moisture of steam and heat recovery and utilization, save energy and resource.For realizing this goal; Adopted such technical scheme: the vapour-condensing equipment for recovering in the production of polyester; Comprise steam-pipe, condensation water tank, multistage water pump and vapour generator; Each steam heating, tracing system condensate ruturn pipe are communicated with the vapor condensation water tank, and at least two group nozzles are installed in each condensate ruturn pipe.The part that condensate ruturn pipe is installed nozzle should be in vapor condensation water tank top, and is vertical direction.The water inlet pipe of multistage water pump is drawn from the bottom in the water tank, and the rising pipe one tunnel of multistage water pump is communicated with vapour generator, and another road is communicated with the nozzle in the condensate ruturn pipe.
The utilization of the vapour-condensing equipment for recovering in the production of polyester makes steam in the condensate ruturn pipe through multistage water pump self-circulation spray, and 90% recoverys that be captured realized recycling of water of condensation, reduced one-level soft usage quantity, day about 60m of the saving water yield 3The vapor condensation water tank has been because collected the heat of water vapour, and the temperature that makes water is elevated to about 80 ℃ from original 50 ℃, and high temperature soft water is delivered to vapour generator through stage pump and recycles, and has realized heat integration, energy efficient.
Description of drawings: Fig. 1 is the vapour-condensing equipment for recovering structural representation in the production of polyester.
Embodiment: be further described below in conjunction with accompanying drawing.
Vapour-condensing equipment for recovering in the production of polyester comprises steam-pipe, condensation water tank, multistage water pump and vapour generator.The companion of each steam heating, tracing system is hot, heat form is different, temperature, pressure difference, and companion's heat, heating completion rear section vapor condensation Cheng Shui still have the steam of considerable part to have higher temperature.Condensate ruturn pipe 2 is communicated with vapor condensation water tank 1, and two groups of nozzles 3 up and down are installed in each condensate ruturn pipe.The part that condensate ruturn pipe is installed nozzle should be in vapor condensation water tank top, and is vertical direction.Water vapor condenses into water under the spiral water smoke cooling of nozzle ejection, reduced soft consumption.The heat of water vapor has improved the temperature of water in the condensation water tank simultaneously, and no longer runs off along with discharge of steam.The water inlet pipe of multistage water pump 4 is drawn from the bottom in the water tank.The rising pipe one tunnel of multistage water pump is communicated with the nozzle of condensate ruturn pipe, and another road of multistage pumping line is communicated with vapour generator 5, high-temperature water is sent into vapour generator saved energy consumption.
