Abstract
The invention relates to a device for recycling steam condensate during production of anhydrous hydrogen fluoride. The device comprises a rectifying tower reboiler and a degassing tower reboiler, wherein the rectifying tower reboiler and the degassing tower reboiler are connected with a horizontal storage tank through pipelines; and the horizontal storage tank is connected with a water supply storage tank of a steam manifold of a coal economizer through a recovery pump. Due to the adoption of the device, the cost is reduced, the temperature of steam generated by the coal economizer is raised from 140 DEG C to 144 DEG C, the heat quantity of the steam is increased, and greater economic benefit is generated; and meanwhile, the social benefits of saving energy, reducing emission and lowering pollution are achieved.
Description
Technical field
The present invention relates to a kind of anhydrous hydrogen fluoride production reclamation of condensate water use device.
Background technology
In the anhydrous hydrogen fluoride production process, thick hydrofluoric making with extra care is the emphasis of whole technological operation, technological process is: thick hydrofluoric acid condensate liquid enters rectifying column after thick hydrofluoric acid pump pressurization, material carries out gas-liquid mass transfer, heat transfer in rectifying tower system after, heavy component accumulates in tower reactor, again through the rectifying column reboiler, becomes gas and returns rectifying column, participate in gas-liquid mass transfer, heat transfer, reach the purpose that heavy component in the hydrogen fluoride is separated.Low-boiling-point substance and the HF gas of discharging from rectifying tower top enter degassing tower after the rectifying column condenser condenses.Material is removed light component SO2, SiF4, CO2, O2, N2 wherein in the degassing tower system.Finally make pure anhydrous hydrogen fluoride liquid.Hydrofluoric acid liquid becomes gas by liquid in rectifying column reboiler, degassing tower reboiler realizes by Steam Heating, produces in this course per hour 3 tons, the condensed water that temperature is 140 ℃.The condensed water that produces generally enters outer drainage pipeline by the ditch, causes larger waste.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and can avoid the condensed water waste, and the anhydrous hydrogen fluoride production reclamation of condensate water use device of the energy is provided for subsequent production.
Anhydrous hydrogen fluoride production reclamation of condensate water use device provided by the present invention, comprise rectifying column reboiler and degassing tower reboiler, described rectifying column reboiler is connected pipeline with the degassing tower reboiler and connects horizontal tank, and horizontal tank connects the economizer drum to water storage tank by reclaiming pump.
Described horizontal tank is six cubic metres carbon steel storage tank.The volume of selected storage tank and material mainly are that accomplish can be corrosion-resistant with reference to the speciality of condensed water in rectifying column reboiler and the degassing tower reboiler.With six cubic metres storage tank, for the discharging of condensed water provides enough power, reduce the operating pressure that reclaims pump.
Described recovery pump comprises that first reclaims pump and second and reclaim pump, and first reclaims pump and be connected the import of reclaiming pump and connect the outlet pipe of horizontal tank, and first reclaims pump reclaims delivery side of pump and be connected with the water inlet of economizer drum to water storage tank with being connected.Work simultaneously by two recovery pumps, make cool solidifying water enter the economizer drum and enter follow-up economizer drum to enough its of the pressure of water storage tank, convenient production.
Described economizer drum connects the economizer drum to water storage tank.
The beneficial effect that the present invention has is not only to have reduced cost, and improved the vapor (steam) temperature that economizer produces, bring up to 144 ° by original 140 °, increased the heat of steam, long-living larger economic benefit has again energy-saving and emission-reduction simultaneously and avoids the social benefit polluted.

Among the figure: 1, horizontal tank; 2, first reclaim pump; 3, second reclaim pump; 4, the economizer drum is to water storage tank; 5, economizer drum.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
Anhydrous hydrogen fluoride production reclamation of condensate water use device as shown in Figure 1, comprise rectifying column reboiler and degassing tower reboiler, described rectifying column reboiler is connected pipeline with the degassing tower reboiler and connects horizontal tank, and horizontal tank 1 connects the economizer drum to water storage tank 4 by reclaiming pump.Horizontal tank 1 is six cubic metres carbon steel storage tank.The volume of selected storage tank and material mainly are that accomplish can be corrosion-resistant with reference to the speciality of condensed water in rectifying column reboiler and the degassing tower reboiler.With six cubic metres storage tank, for the discharging of condensed water provides enough power, reduce the operating pressure that reclaims pump.
Reclaim pump and comprise that first reclaims pump 2 and second and reclaim pump 3, the first and reclaim pumps 2 and be connected the import of reclaiming pump 3 and connect the outlet pipe of horizontal tank 1, first reclaims pump reclaims delivery side of pump and is connected with the water inlet of economizer drum to water storage tank 4 with being connected.Work simultaneously by two recovery pumps, make cool solidifying water enter the economizer drum and enter follow-up economizer drum 5 to enough its of the pressure of water storage tank 4, convenient production.
