Abstract

The utility model discloses a flash steam recovery system characterized in that for the condition of heat loss due to the fact that steam produced in a high-temperature condensate water delivery process by a steam pump scatters into the atmosphere when entering a hot water tank, a heat exchanger is installed above a condensate water pipeline, and the flash steam is absorbed while cold water is heated to be used for company production, so that the energy is saved, and the environment is protected. The flash steam recovery system is concise in structure and obvious in effect and has very enormous economic and social benefits.

Description

A kind of flash steam recovery system
Technical field
The utility model relates to a kind of flash steam recovery system.
Background technology
In chemical process; utilizing Steam Heating material to carry out chemical reaction is a kind of technological means of often using; Steam Heating material heat energy becomes condensed water after discharging, and for saving water resource protection of the environment, condensed water is mostly sent the feed water system of boiler back to and recycled.Yet high-temperature condensation water, owing to containing certain steam, should not be carried with conventional centrifugal pump, easily produce cavitation erosion.Therefore, conventionally adopt in process of production heat pump to carry high-temperature condensation water to avoid the problem of cavitation erosion.But utilize heat pump to carry the process of high-temperature condensation water also to have following defect:
When 1, high-temperature condensation water adopts heat pump to carry, steam consumption quantity is large, but is not fully utilized.
2, in condensed water, add water temperature after steam to rise, radiation loss increases.
3, in course of conveying, owing to there being steam water interface to increase pipe, press, easily cause pipe vibration, produce destructive power.
Utility model content:
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of flash steam recovery system is provided, can fully recycle a large amount of steam and rich heat energy that high-temperature condensation water produces in course of conveying, when absorbing flash steam, heat cold water, avoid the waste of the energy.
The utility model is that technical solution problem adopts following technical scheme:
The design feature of a kind of flash steam recovery system of the utility model is: a heat exchanger with cold water channel and hot water channel is set, and the flash steam in the condensate pipe being connected with heat pump forms delivery to boiler enter the heat exchanging pipe of described heat exchanger by described hot water channel after; Described heat exchanger is delivered to cooling water outlet after accepting the cold water of described cold water channel conveying simultaneously and utilizing heat exchanging pipe to obtain the cold water heating.
The design feature of the utility model flash steam recovery system is also: described heat exchanger is positioned at the top of described condensate pipe.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model utilizes heat exchanger to reclaim the flash steam of high-temperature condensation water in course of conveying, not only reduced the overall thermal enthalpy of high-temperature condensation water, reduced water temperature and eliminated the steam in carbonated drink mixture, having avoided the vibration limits of water pipe, having guaranteed the delivery safety of high-temperature condensation water; And can when absorbing flash steam, cold water be heated by heat exchanging pipe become production process in needed hot water, avoided the loss of heat, improved the recovery utilization rate of the energy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: 1 heat exchanger; 2 heat pumps; 3 condensate pipes; 4 boilers; 5 flash steams are got steam ports; 6 inlet valves; 7 cooling water inlet valves; 8 cooling water outlet valves; 9 hot water valve; 10 bypass valves; 11 repumping houses; 12 bathe wash pool; 13 condensation water tanks.
The specific embodiment
In the present embodiment, a kind of flash steam recovery system is for adopting heat pump 2 to carry the flash steam of the high-temperature condensation water in condensation water tank 13, when entering boiler 4, spill into the situation that atmosphere causes heat loss, one heat exchanger 1 with cold water channel and hot water channel is set, and the flash steam in the condensate pipe 3 being connected with heat pump 2 forms delivery to boiler 4 enter the heat exchanging pipe of heat exchanger 1 by hot water channel after; Heat exchanger 1 is delivered to cooling water outlet after accepting the cold water of cold water channel conveying simultaneously and utilizing heat exchanging pipe to obtain the cold water heating.In concrete enforcement, cold water can be provided by repumping house 11, and the cold water after heating can be delivered to bathes wash pool 12.
In concrete installation, at conveying high-temperature condensation water pipeline 3 tops, connect a Dn300 flash steam and get steam ports 5; Heat exchanger 1 is arranged in, 4 meters of tops of condensate pipe 3; Pipeline medium is steam water interface, and steam proportion is less, heat exchanger is arranged in to the top of pipeline, can carry out to maximum flash distillation.Flash steam enters after heat exchanger 1, utilizes the method for flash distillation by heat absorption in high-temperature condensation water, simultaneously by tubulation heat exchange principle, and the cold water that utilizes heat energy heating to be carried by cold water channel; After flash steam is cooling, become hot water and introduce boiler 4.And send into production subsidiary factory by cooling water outlet after cool water heating, use, both met the demand of production company to hot water, guarantee the delivery safety of high-temperature condensation water, again fully recycling rich heat energy and quantity of steam in high-temperature condensation water, energy-conserving and environment-protective.
When putting into operation, first drive cooling water inlet valve 7, then drive cooling water outlet valve 8, substantially meet company's production water yield needs, by production subsidiary factory replenishment control water level, then slowly open the inlet valve 6 of flash steam, regulate water temperature to 50 ℃ left and right, production subsidiary factory need to regulate water temperature again according to technique.
And need first close the inlet valve 6 of flash steam when stopping transport, then close cooling water outlet valve 8 and cooling water inlet valve 7.When production subsidiary factory needs promptly to stop using heat exchanger 1 in case of exceptional circumstances, should first open bypass valve 10 and enter trench, after close hot water valve 9.Simultaneously according to normal step stoppage in transit heat-exchange system.
