The excess steam that produces in paper-making process at present all can be recycled, and the method for employing is these steam to be sent into carry out heat exchange generation condensate water in the drying cylinder; By drain valve condensate water is discharged; Send into again in the boiler; In the pumped back boiler.Because the heat-energy losses of boiler is large, the condensing water temperature of sending boiler back to is low, and the coal consumption of heating generation steam is large again, the waste resource.And the hydrophobic effect of drain valve is poor, can cause condensate water not discharge fully.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of energy consumption and high vapour-recovery unit of rate of heat exchange of reducing is provided.
The technical solution of the utility model is achieved in that
A kind of vapour-recovery unit, it comprises:
Be used for after heat exchange is carried out in inside, becoming after steam enters the drying cylinder of condensed water in high temperature;
Be used for the drain valve pump with the discharge of the condensed water in high temperature in the drying cylinder;
For the heat exchanger that the vapour-recovery unit extraneous air is carried out preheating;
Be used for removing the gas of condensate water and the condensate water recycling machine that condensed water in high temperature is incubated;
Be used for pumping the heat-exchanger pump of condensed water in high temperature;
Be used for that the vapour-recovery unit extraneous air heats and condensed water in high temperature become the boiler of steam,
Drying cylinder the same side connects respectively steam and enters pipe and condensed water in high temperature discharge pipe; The condensed water in high temperature discharge pipe also connects an end of drain valve pump, and the other end of drain valve pump connects the heat exchanger that is positioned at the top by input pipe; Heat exchanger connects the end be positioned at the condensate water recycling machine under it by carrier pipe again; The other end of condensate water recycling machine connects heat-exchanger pump; Heat-exchanger pump connects boiler.
Described drain valve pump comprises drain valve and pump.
The number of the heat-exchanger pump in the described vapour-recovery unit is two, and two heat-exchanger pumps are connected in parallel between condensate water recycling machine and boiler.
Of the present utility model by adopting the drain valve pump, its compact conformation, hydrophobic efficient height; Adopt the condensate water recycling machine, can prevent the heat energy loss of condensate water, and then reduce the required coal consumption of boiler that energy-saving effect is obvious.

The specific embodiment
Consult shown in Figure 1, a kind of vapour-recovery unit of the utility model, it comprises successively drying cylinder 1, drain valve pump 2, heat exchanger 3, condensate water recycling machine 4, heat-exchanger pump 5 and the boiler 6 that connects.The same side of drying cylinder 1 connects respectively steam and enters pipe 7 and condensed water in high temperature discharge pipe 8, this condensed water in high temperature discharge pipe 8 connects an end of drain valve pump 2, the other end of drain valve pump 2 connects the heat exchanger 3 that is positioned at the top by input pipe 9, heat exchanger 3 connects an end of the condensate water recycling machine 4 under being positioned at again by carrier pipe 10, the other end of condensate water recycling machine 4 connects heat-exchanger pump 5, and heat-exchanger pump 5 also connects boiler 6.Drain valve pump 2 in the utility model comprises drain valve and pump, and such device setting height(from bottom) is low, and hydrophobic rate is high.Input pipe 9 and carrier pipe 10 are arranged on the same side of heat exchanger 3 and condensate water recycling machine 4.The utility model adopts two heat-exchanger pumps 5, and these heat-exchanger pumps 5 are connected in parallel between condensate water recycling machine 4 and the boiler 6.
The operation principle of vapour-recovery unit of the present utility model is as follows:
1) steam of at first underusing in paper technology enters pipe 7 by steam and enters drying cylinder 1, and steam carries out heat exchange and generates condensed water in high temperature in drying cylinder 1;
2) then condensed water in high temperature is discharged by condensed water in high temperature discharge pipe 8 from drying cylinder 1 by drain valve pump 2, does not carry out the steam of heat exchange and can not discharge;
The condensed water in high temperature of 3) discharging enters heat exchanger 3 by the power of drain valve pump 2 by input pipe 9, heat exchanger 3 utilizes inner condensed water in high temperature to carry out preheating to the air of outside, because need extraneous gas to reach certain temperature in the paper technology, can effective use of energy sources by heat exchanger 3, save cost;
4) condensed water in high temperature continues transported to condensate water recycling machine 4 through carrier pipe 10, this equipment can be that the condensed water in high temperature that enters is not vaporized, namely remove the gas that is mixed in the condensed water in high temperature, can not corrode so inner water pump, and the condensate water recycling machine can to being incubated of condensed water in high temperature, prevent heat radiation;
5) the final high temperature condensate water is transported in the boiler 6 by heat-exchanger pump 5, condensed water in high temperature heats generating steam in boiler 6, this steam can be used for paper technology, and this boiler 6 also can heat the air of outside, makes the temperature of air satisfy the demand of paper technology.
Vapour-recovery unit novel structure of the present utility model, hydrophobic effect is good, and rate of heat exchange is high, has reduced coal consumption; And effective use of energy sources heats extraneous air, saves cost.
