Background technology
At present, general steam condensate recovery system has two kinds of open type recovery system and enclosed recovery systems.Wherein, the open type recovery system is that condensate water enters a tank collection back that is communicated with atmosphere with the pump conveying, can lose a large amount of heats like this, and increase the oxygen content of condensate water, also can cause thermal pollution to periphery simultaneously; The enclosed recovery system then is that the condensate water of one or more pressure ratings is concentrated recovery by a container with pressure, though avoided the shortcoming of open type recovery system, but because steam and the difference of condensate water pressure and the pressure differential of different pressures condensate water, recovery system exist the low condensate water of back pressure hydrophobic, reclaim not freely, therefore have the problem that can not reclaim fully.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides and a kind ofly can reclaim the condensate water of different pressures grade fully, smoothly, and can avoid losing, wasting the enclosed steam condensate recovery system of condensate water.
For achieving the above object, the utility model is taked following technical scheme: a kind of enclosed steam condensate recovery system, it is characterized in that: it comprises high and low pressure two-way steam condensate reclaim line, described high steam condensate return pipe road comprises a condensate water climb device, an enclosed Condensate recovery device and a condensate transfer pump, with hot equipment the high steam condensate water is gathered to a house steward by hydrophobic pipeline, be delivered in the described Condensate recovery device through the described condensate water device of climbing; When the high steam condensate water of collecting in the described Condensate recovery device reaches predefined liquid level, by the liquid level sensor in the described Condensate recovery device signal is transferred to described condensate transfer pump, described condensate transfer pump starts, and the high steam condensate water is delivered in the oxygen-eliminating device; Described low-pressure steam condensate return pipe road comprises another condensate water climb device, another enclosed Condensate recovery device and another condensate transfer pump, the low-pressure steam condensate water gathers to another house steward through hydrophobic pipeline, after described another condensate water of process is climbed device, another enclosed Condensate recovery device and another condensate transfer pump successively, the low-pressure steam condensate water is also delivered in the described oxygen-eliminating device; The output pipe of described two condensate transfer pumps is connected.
Be provided with a drain valve on each described hydrophobic pipeline, and each described drain valve adopts all and can utilize condensate water sensible heat, heat static force type drain valve that the highest permission back pressure is lower.
The output port of two described condensate transfer pumps is respectively arranged with a check-valves.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to adopted high and low pressure two-way steam condensate reclaim line, the high and low pressure steam condensate is climbed behind device, enclosed Condensate recovery device and the condensate transfer pump through condensate water successively, by condensate transfer pump the high and low pressure steam condensate is delivered in the oxygen-eliminating device, to reduce the oxygen content in the condensate water.Therefore, realized to reclaim fully, smoothly the function of the condensate water of different pressures grade.2, therefore the utility model can unimpededly be delivered to the steam condensate pressurization in the oxygen-eliminating device owing to the output port at two condensate transfer pumps is respectively arranged with check-valves, and then has avoided loss, waste condensate water.The utility model can be widely used in molten sulphur workshop section of acid production with sulphur manufacturing enterprise or other similar have that steam condensate produces use vapour enterprise.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises high and low pressure two-way steam condensate reclaim line 1 and 1 ', wherein high steam condensate return pipe road comprises a condensate water climb device 2, an enclosed Condensate recovery device 3 and a condensate transfer pump 4, with hot equipment the high steam condensate water is gathered to a house steward 5 by hydrophobic pipeline, by house steward 5 the high steam condensate water is delivered to condensate water and climbs in the device 2, by the condensate water device 2 of climbing the high steam condensate water is delivered in the Condensate recovery device 3 again.When the high steam condensate water of collecting in the Condensate recovery device 3 reaches predefined liquid level, by the liquid level sensor in the Condensate recovery device 3 signal is transferred to condensate transfer pump 4, and then start condensate transfer pump 4.Condensate transfer pump 4 is delivered to the high steam condensate water in the oxygen-eliminating device 6 in the power houses, and then the oxygen in the high steam condensate water is removed, and reduces the oxygen content in the high steam condensate water.
Low-pressure steam condensate return pipe road 1 ' comprises a condensate water climb device 2 ', an enclosed Condensate recovery device 3 ' and a condensate transfer pump 4 ', its connected mode is identical with the connected mode on high steam condensate return pipe road 1, the low-pressure steam condensate water gathers to another house steward 7 through hydrophobic pipeline, climb behind device 2 ', enclosed Condensate recovery device 3 ' and the condensate transfer pump 4 ' through condensate water successively, the low-pressure steam condensate water is also delivered in the oxygen-eliminating device 6, to realize reducing the oxygen content in the low pressure condensate water.Wherein, the output pipe of the condensate transfer pump 4 in the condensate transfer pump 4 ' output pipe of low pressure condensate water reclaim line 1 ' and the high pressure condensate return pipe road 1 is connected, and carries thereby the condensate water subnetting of realizing different pressures reclaims condominium.
In the foregoing description, be provided with a drain valve 8 on each hydrophobic pipeline, and each drain valve 8 adopts all and can utilize condensate water sensible heat, heat static force type drain valve that the highest permission back pressure is lower.
In the foregoing description, two condensate transfer pumps 4 and 4 ' output port are respectively arranged with a check-valves 9, so that the steam condensate pressurization unimpededly is delivered in the oxygen-eliminating device 6.
The utility model in use, because the condensate water of different pressures reclaims independent separately, steam condensate is constantly got rid of in enclosed Condensate recovery device 3 and 3 ', make enclosed Condensate recovery device 3 and 3 ' pressure inside keep below pressure forever, thereby guaranteed that steam condensate can not entered in the steam condensate recovery system of the present utility model by the influence of back pressure swimmingly with hot equipment condensed water discharge outlet.
