Abstract
A kind of desalted water adjusting device of raw gas intercooler, belong to raw gas cooling device technical field, technical problem to be solved is to provide the supply of a kind of guarantee raw gas intercooler desalted water, make the device that raw gas intercooler heat transfer effect strengthens, the technical scheme adopted: a kind of desalted water adjusting device of raw gas intercooler, be communicated with desalted water at the desalted water return piping of raw gas intercooler and regulate pipeline, described desalted water regulates pipeline to be connected with chemical water station by air cooler, and regulate between the connectivity points of pipeline and air cooler at described desalted water return piping and desalted water and be also provided with at least one stop valve, the utility model is applied to crude gas cooling technique.
Description
Technical field
A desalted water adjusting device for raw gas intercooler, belongs to raw gas cooling device technical field.
Background technology
In crude gas cooling technique process, by chemical water station, former water is processed as desalted water through chemical water station, then delivers to desalted water pipe network through the pressurization of desalination water pump.But often occur that 400#(raw gas cools in cooling procedure) 40W002 shell-side desalted water return water temperature 40CT021 operation (>85 DEG C) beyond target for a long time, and then cause the long-term standard-sized sheet of 40W002 raw gas bypass valve, 40W002 operating load is on the low side, 40W003 operating load is higher, and then cause 40W003 shell-side circulating backwater temperature 40CT031 to run (>42 DEG C) beyond target for a long time, finally cause 400# raw gas temperature 40CT051 exceed standard (>37 DEG C) bring hidden danger to the stable operation of system. and cause 40W002 shell-side desalted water water shortage to be because be subject to exhaust steam to reclaim shunting action to desalted water, also be subject to the restriction of 231# high water tank simultaneously, the 231# water tank liquid level that works normally is 40%-70%, now desalted water is supply condition, when work liquid level over range, desalted water stops supply, and the condensed water that exhaust steam removal process produces enters 231# water tank and also easily changes its work liquid level.
In above-mentioned term, 40W002 adopted name is raw gas intercooler, 40W003 adopted name is raw gas final cooler, 40CT021 is raw gas intercooler shell-side desalted water return water temperature point for measuring temperature (index is less than 85 DEG C), 40CT031 is raw gas final cooler shell-side recirculated water return water temperature point for measuring temperature (index is less than 42 DEG C), 40CT051 is crude gas cooling number outlet raw gas temperature point for measuring temperature (index is less than 37 DEG C), 231# water tank is low pressure deaeration plant low pressure membrane deaerator water tank, low pressure deaeration plant utilizes stripping principle at 105 DEG C, under 0.02MPa condition, oxygen is removed to from the desalted water of each device and condensate liquid, free CO2 and other incoagulable gas are to meet the needs of boiler feedwater.
Utility model content
Technical problem to be solved in the utility model is to provide the supply of a kind of guarantee raw gas intercooler desalted water, makes the device that raw gas intercooler heat transfer effect strengthens.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of desalted water adjusting device of raw gas intercooler, be communicated with desalted water at the desalted water return piping of raw gas intercooler and regulate pipeline, described desalted water regulates pipeline to be connected with chemical water station by air cooler.
Regulate between the connectivity points of pipeline and air cooler at described desalted water return piping and desalted water and be also provided with at least one stop valve.
The beneficial effect that compared to the prior art the utility model has is: by desalted water regulate pipeline by a part of desalted water through air cooler cooling after, again send into chemical water station, and regulate pipeline to regulate to desalted water in real time by stop valve, thus ensure that the supply of raw gas intercooler desalted water, and then improve the heat transfer effect of 40W002, alleviate the pressure of 40W003 simultaneously, 400# raw gas temperature is run in indication range, greatly reduce the rate of breakdown of equipment, raw gas cooling procedure can be stablized and carries out.
Accompanying drawing explanation
Fig. 1 is the pipe network schematic diagram of raw gas intercooler desalted water in prior art.
Fig. 2 is the pipe network schematic diagram of the utility model raw gas intercooler desalted water.
In figure, 1 is stop valve, and 2 is air cooler, and 3 is desalted water adjustment pipeline, and 4 is desalted water return piping.
Detailed description of the invention
As shown in Figure 2, a kind of desalted water adjusting device of raw gas intercooler, is communicated with desalted water at the desalted water return piping 4 of raw gas intercooler and regulates pipeline 3, and described desalted water regulates pipeline 3 to be connected with chemical water station by air cooler 2.
Regulate between the connectivity points of pipeline 3 and air cooler 2 at described desalted water return piping 4 and desalted water and be also provided with at least one stop valve 1.
Described stop valve 1, air cooler 2 are prior art.
Stop valve 1, according to 40CT021 temperature variations, is slowly opened by operating personnel, will take into account the temperature variations of 40CT021 and the situation of change of 231# high water tank when adjusting stop valve 1 valve size, ensures that projects technic index is qualified.
Claims (2)
1. a desalted water adjusting device for raw gas intercooler, is characterized in that: be communicated with desalted water at the desalted water return piping of raw gas intercooler and regulate pipeline, and described desalted water regulates pipeline to be connected with chemical water station by air cooler.
2. the desalted water adjusting device of a kind of raw gas intercooler according to claim 1, is characterized in that: regulate between the connectivity points of pipeline and air cooler at described desalted water return piping and desalted water and be also provided with at least one stop valve.
