Abstract
The utility model relates to a comprehensive utilization device of neopentyl glycol steam afterheat and excessive pressure. The comprehensive utilization device of the neopentyl glycol steam afterheat and excessive pressure comprises a steam condensate recovery device (3), wherein the liquid inlet end of the steam condensate recovery device (3) is connected with a steam condensate pipeline (1) on a production line through a first valve (2); the liquid outlet end of the steam condensate recovery device (3) is connected to the liquid inlet end of a buffer tank (5) through a second valve (4); the liquid outlet end of the buffer tank (5) is connected with the liquid inlet end of a high-temperature hot water pump (7) through a third valve (6); and the comprehensive utilization device is characterized in that the liquid outlet end of the high-temperature hot water pump (7) is connected with a plug-in evaporator (9). The comprehensive utilization device has the advantages that the waste phenomenon of secondary flash steam in much condensate is stopped; the steam consumption is saved; the capacity of a processing unit is expanded, and the production cost is greatly reduced.
Description
Technical field
The utility model relates to the waste heat overbottom pressure comprehensive utilization device of high-temperature condensation water, particularly relates to the high-temperature condensation water waste heat overbottom pressure comprehensive utilization device in a kind of process of producing neopentyl glycol.
Background technology
High-temperature steam condensed water in the existing neopentyl glycol technique directly flows back to the condensation liquid bath, then by the past boiler utilization of pumping, secondary flash distillation heat in the steam condensate (SC) directly runs not wasted in the atmosphere by condensate liquid emptying and is utilized, thereby increased the loss of product steam, increased production cost.
Summary of the invention
The purpose of this utility model is the problem that solves a large amount of losses that have the high temperature condensate liquid in the process of producing neopentyl glycol now, and a kind of neopentyl glycol steam waste heat overbottom pressure comprehensive utilization device is provided.
The objective of the invention is to be achieved by the following technical programs:
Neopentyl glycol steam waste heat overbottom pressure comprehensive utilization device, comprise steam condensate recovering device, the liquid feeding end of steam condensate recovering device is connected with steam-condensation waterpipe on the production line by the first valve, its outlet end is connected with the liquid feeding end of dashpot by the second valve, the outlet end of dashpot is connected with the liquid feeding end of high temperature hot water pump by the 3rd valve, it is characterized in that the outlet end of high temperature hot water pump is connected with plug-in evaporimeter.
Adapter between the outlet end of described high temperature hot water pump and the liquid feeding end of plug-in evaporimeter is provided with the 4th valve, is used for the flow of this section of control high-temperature condensation water.
Described plug-in evaporimeter is the existing product that the market can be purchased.
The beneficial effects of the utility model are: stopped secondary flash steam wasting phenomenon in a large amount of condensate liquids, the steam saving consumption enlarges the process unit production capacity, significantly valency is low production cost.
Following constipation closes drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is that the utility model uses view.
The specific embodiment
As shown in Figure 1, the utility model comprises steam condensate recovering device 3, the liquid feeding end of steam condensate recovering device 3 is connected with steam-condensation waterpipe 1 on the production line by the first valve 2, the outlet end of steam condensate recovering device 3 is connected with the liquid feeding end of dashpot 5 by the second valve 4, the outlet end of dashpot 5 is connected with the liquid feeding end of high temperature hot water pump 7 by the 3rd valve 6, and the outlet end of high temperature hot water pump 7 is connected with the liquid feeding end of plug-in evaporimeter 9 by the 4th valve 8.
The course of work
Producing neopentyl glycol need to pass through synthesizing section, the workshop section of dewatering, put forward pure workshop section and these several processes of rectifying workshop section, the high-temperature steam condensed water that produces in this process reclaims by steam condensate recovering device 2 through high-temperature condensation water pipeline 1, be collected in the dashpot 5, through high temperature hot water pump 7 pressurizations the high-temperature steam condensed water is delivered in the plug-in evaporimeter 9, utilize the heat of high-temperature steam condensed water for evaporimeter, in whole process, control the high-temperature steam condensed water by the first valve 2, the second valve 4, the 3rd valve 6 and the 4th valve 8.
In sum, the utility model is by having increased plug-in evaporimeter on the original technique basis that produces neopentyl glycol, enlarged in process of production device capbility, steam heat recovery heat energy is for increasing evaporimeter simultaneously, stop secondary flash steam wasting phenomenon in a large amount of condensate liquids, realized energy-saving and emission-reduction.
