Description
Technical field
The utility model relates to pure steam generating equipment technical field.
Background technology
In pharmaceutical industry production technology, pure steam is used for the damp and hot aseptic process that aseptic medicine, material, container, equipment, aseptic clothing or other article need enter sterile procedures district, simultaneously also for air wetting in clean room.Pure steam is prepared by pure steam generator, afterwards by Cemented filling to each in medicament compartment toilet with vapour point (hereinafter referred to as with point).According to 2010 editions Chinese Pharmacopoeias (Pharmacopoeia of People's Republic of China version in 2010) requirement, pure quality of steam test stone is whether its condensate water meets water for injection standard.Therefore, need each use point place at pure steam, pure steam is sampled, verifies whether its condensate water meets water for injection standard.
Existing pure steam sampling device is always divided into 2 classes:
The first kind is independent pure stram condenser, and its structure as shown in Figure 1.
Stram condenser is equivalent to a tube exchanger, walks pure steam, walk chilled water in shell side in tube side.Pure steam is by the top of with point introducing coil pipe of flexible pipe from pure steam, and enter tube side, then pass through and the chilled water heat exchange in shell side, be condensed into condensate water, condensate water flows out from the bottom of coil pipe.Complete the sampling work to pure steam.
Although this pure steam condenser structure is simple, difficulty of processing is low, very inconvenient in pharmacy corporation sampling process, sometimes even cannot complete sampling work.Reason is: need to use a large amount of chilled waters in this stram condenser sampling process and carry out heat interchange, and usually not for it arranges water supply point and the drainage point of independent chilled water in the toilet of pharmacy corporation.In order to complete the sampling work of pure steam, other in chummery can only be utilized with water spots, such as, utilize the purified water water spot of normal temperature or softening water water spot to serve as chilled water, the shell side being received stram condenser by two very long flexible pipes is is respectively imported and exported.If do not have the discharge of wastewater such as pond or floor drain point in room, can only be collected by the waste water after heat exchange by artificial container, being then transported to other has the room of emission point to discharge.If do not have other to use water spot in chummery, can only use and serve as chilled water with water spot in neighbouring room, but the division be limited by between the lustration class different from clean area the unidirectional restriction of logistics of the stream of people in toilet, spaced far apart sometimes between the two, longer flexible pipe can only be used to carry out being connected water supply through between gate inhibition with buffering, hose length reaches tens meters even tens meters, needs two personal synergics just can complete sampling work simultaneously.Because flexible pipe will pass gate inhibition, need gate inhibition to open, this, by the positive air pressure between the different toilet of destruction or negative pressure requirement, easily produces diffusion and the cross contamination risk of virus, engineering bacteria or pollutant.If in order to avoid above-mentioned risk, do not allow gate inhibition to open, then cannot complete the sampling work of pure steam.This device also has a shortcoming to be exactly, after pure steam enters tube side, directly flow out below tube side by gravity, because pure steam or the condensate water residence time inside tube side is shorter, cannot ensure the leaving water temperature of condensate water.Even sometimes, the inlet of pure steam is excessive, and what flow out from the tube side of stram condenser is steam water interface, and temperature reaches more than 100 DEG C, and easy generation personnel scald.
Equations of The Second Kind is pure steam sampling dolly, and its structure as shown in Figure 2.
Pure steam sampling dolly is the extending design done on the basis of first kind stram condenser, and its critical piece is stram condenser (being tube exchanger equally), cooling water tank, centrifugal pump.Chilled water is stored in cooling water tank, after chilled water goes out in water tank, be connected to centrifugal pump by pipeline and carry out supercharging, be then delivered to stram condenser shell side inlet, after steam heat-exchanging in chilled water and tube side, flow to again in cooling water tank from the outlet of stram condenser shell side.Pure steam, by the top of with point introducing coil pipe of flexible pipe from pure steam, enters tube side, is condensed into condensate water in tube side, complete the sampling work of pure steam.Conveniently move, usually the assemblies such as stram condenser, cooling water tank, centrifugal pump are installed on a mobile platform, therefore are called pure steam sampling dolly.

Second: the centrifugal pump on this pure steam sampling dolly needs the alternating current of 220V to drive.The conveniently scouring of colored steel, sterilization and hygiene in usual toilet, not design communication electricity power supply base, so can only use the power supply base in chummery on consumer inside self-control cabinet.If there is no consumer in room, or do not design power supply base inside its self-control cabinet, the power supply base inside self-control cabinet on the consumer in other rooms of annex can only be used.The problem produced and risk are with first kind stram condenser: not only power lead is very long, need two people's cooperations, and easily produce diffusion and the cross contamination risk of the virus in room, different toilet, engineering bacteria or pollutant, even cannot complete sampling work.

Principle of work:
Portable pure steam sampling device (as shown in Figure 3) ultimate principle that one-level stops formula cooling mode is that pure steam and chilled water carry out heat exchange in the pure stram condenser of one-level, carries out condensation and cooling to pure steam.The heat that chilled water is taken away carries out heat exchange with air in firsts and seconds air radiator, again becomes low-temperature cooling water, then enters in the pure stram condenser of one-level.Chilled water is a medium, and the heat of pure steam is carried to inside air, and cooling water circulation uses.Utilize centrifugal pump to provide power for cooling water circulation, utilize blower fan that large quantity of air is dispelled the heat to chilled water by firsts and seconds air radiator, utilize battery or Switching Power Supply to provide electric power for centrifugal pump and blower fan.
The principle of work of specific descriptions and all parts is as follows:
The a large amount of pure steam utilizing flexible pipe to be located by pure steam point introduces the entrance of portable pure steam sampling device, restriction orifice is utilized to carry out current limliting to the pure steam entering condenser afterwards, realize a small amount of pure steam first to enter condenser and carry out condensation, meet sampling requirement; Second, prevent the diaphragm valve aperture in exit excessive, a large amount of pure steam enters condenser, has little time condensation, and then with the form of steam water interface ejection condenser, the personnel that cause scald.A small amount of pure steam enters after condenser after tube side, and carry out heat exchange with the chilled water in condenser shell side, become condensate water, condensate water flows downward, and flows out condenser.The temperature sensor exported by condenser tube side is detected its temperature, is then shown on condensate temperature display.Condensate water is through manual diaphragm valve afterwards, is flowed in condensation water collection bottle (receiving flask is exactly a bottle with a lid, for collecting pure steam condensate (SC), then takes test in laboratory water-quality guideline, not being included in inside this sampler) by mozzle.Manual diaphragm valve not all are opened, and it keeps certain aperture, namely realizes a part of condensate water and is present in tube side, realize again condensate water and flowed out by diaphragm valve, and the condensation water quantity of outflow and the pure quantity of steam entering tube side match; Object ensures that a part of condensate water is stayed in tube side, continues to carry out heat exchange with the chilled water in shell side, cools condensate water, after making the temperature reduction of condensate water, then flows out shell side.The aperture of manual diaphragm valve regulates according to the condensate temperature on condensate temperature display, if condensate temperature is too high, the aperture of manual diaphragm valve diminishes; If condensate temperature is too low, the aperture of manual diaphragm valve becomes large.This is one-level and stops formula cooling mode, can the leaving water temperature of easier adjustment condensate water, prevents personnel from scalding.
