Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present invention is applied to low-temperature heat still system, low-temperature heat still system includes heating kettle 1(low-temperature heat still) and homoiothermic steam mixing valve 2(abbreviation mixing valve), heating kettle 1 is provided with interlayer.Heating kettle 1 is provided with zone of heating 3, homoiothermic steam mixing valve 2 is provided with cold water inlet 4, steam inlet 5 and recirculated water entrance 6, pipeline connection is passed through between homoiothermic steam mixing valve 2 and heating kettle 1, the zone of heating 3 of heating kettle 1 is connected by pipeline circulating pump 7, circulating pump 7 connects with recirculated water entrance 6, described cold water inlet 4 connects cold water pipe 8, and steam inlet 5 connects has steam pipe 9, steam pipe 9 to be provided with air relief valve 10.It is equipped with angle pedestal valve 11 on cold water pipe 8 and steam pipe 9.Homoiothermic steam mixing valve 2 controls connection control system, and control system can control the switch of each valve of whole system, and monitor and control homoiothermic steam mixing valve 2.
The invention solves the problems that two problems:
First problem: solve steam and directly enter in heating kettle heating interlayer by mixing valve, form sharp pounding and huge noise problem.
Analysis reason:
The mixing valve 2 selected is electrical control steam-water mixing valve that the U.S. produces, and is called for short mixing valve, and this mixing valve 2 uses ceramic cartridge, exit swirl steam and water mixing, realizes accurate temperature control by controller.This mixing valve is originally as low noise steam-water mixing valve.But in experimentation, the most first drive water into and open steam again, or open cold water after first opening steam and open steam and cold water the most simultaneously, all there will be steam and directly entered in heating kettle interlayer by mixing valve, cause the sharp pounding of heating kettle and huge noise.
Air blasting phenomenon Producing reason is that steam-water mixing valve is during performing homoiothermic, no matter design temperature is how many, as long as design temperature is higher than the mixing valve outlet temperature not leading to steam, mixing valve all can be transferred to maximum position steam side, as long as there being steam to be passed through, during mixing valve regulates temperature and turns down steam, some vapor has been had to be directly entered low-temperature heat still interlayer by mixing valve, mix rapidly with the cold water in interlayer, serious air blasting phenomenon will be produced.
In conjunction with this mixing valve 2 principle, use following step:
A1 walks, and makes mixing valve 2 be adjusted to the state that the fully closed disconnected cold water of steam is opened entirely by control system；
A2 walks, and opens the angle pedestal valve 11 being located on cold water pipe 8, logical cold water, then opens the angle pedestal valve 11 being located on steam pipe 9, logical steam；
A3 walks, and mixing valve 2 time delay progressively tuned up steam inlet amount from minimum, until reaching hot water temperature after system requirements mixing after 2 seconds；
A4 walks, and turns off before mixing valve 2 and first the steam inlet amount of mixing valve 2 to be transferred to minimum, shutting off steam again after time delay 2 seconds, finally turns off cold water；
A5 walks, and all are switched on and off mixing valve 2 work and are performed both by above-mentioned A1 step and walk to A4.
The most thoroughly solving steam and directly enter low-temperature heat still Problem of Interlayer by mixing valve, the system that the most thoroughly solves runs the sharp pounding and huge noise problem caused.
Second Problem: solve steam-water mixing valve during adding thermal medium to low-temperature heat still interlayer, the huge noise problem of generation.
Analyze reason: when manually adding thermal medium to low-temperature heat still interlayer or system detects that low-temperature heat still interlayer adds thermal medium deficiency when automatically adding, because of soft water injected system pressure itself and steam pressure, pressure differential is formed in steam-water mixing valve exit, affect the formation of the eddy current steam-water mixing of steam-water mixing valve self design, directly mix with cold water to making steam inject in cold water with normality form, huge noise will be formed.
Concrete settlement steps to deal is:
B1 walks, and (the most manually adds when low-temperature heat still 1 adds thermal medium to interlayer or system is added automatically), first mixing valve 2 design temperature is set to less than room temperature (room temperature), such as less than 20 C；
B2 walks, and opens the soft water valve leading to low-temperature heat still 1, by mixing valve 2, low-temperature heat still 1 is added soft water；
B3 walks, and after the process of adding water terminates to close soft water valve, system delay begins to warm up homoiothermic work for 240 seconds again；
B4 walks, and detects feed liquid and carries out heating operation.
System design principle: soft water adding procedure turns down steam-water mixing valve design temperature, mixing valve is made to be automatically switched off steam inlet, time delay process is to the steam power pump grace time of overfall, the complete excessive soft water of dispatch is to soft water recovery system, it is in atmospheric pressure state reaching steam-water mixing valve exit, make steam-water mixing can form eddy current mixing, to reduce noise.
