Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but be not intended to limit the scope of the present invention.
Join shown in Fig. 1, present embodiments provide a kind of shell and tube vapourizing unit, including cylinder 5, cylinder 5 is by stainless steel tube
It is made (or stainless steel plate is welded), a diameter of D, 5 both ends of cylinder are welded with barrel body end cover 51, by suitable in barrel body end cover 51
When interval, more internal diameters of welding are the stainless steel tubulation 8 that d length is L, and ethylene oxide is heated by tubulation 8 and vaporized.
Barrel body end cover 51 should ensure that the leakproofness of cylinder 5 after being welded with cylinder 5 and tubulation 8, must not be leaked through pressure testing.
5 upper side of cylinder is welded with outlet pipe 11, and downside is welded with water inlet pipe 12, and hot water enters after cylinder 5 from water inlet pipe 12 through outlet pipe
11 outflows.
The barrel body end cover 51 of 5 upper/lower terminal of cylinder is connected separately with upper cover 2 and low head 9, upper cover 2 and low head 9
End face be welded with flange 21,2 top surface of upper cover is welded with ethylene oxide gas air outlet pipe 1, and 9 top of low head is welded with epoxy
The flange 21 of ethane gas air inlet pipe 10, upper cover 2 and low head 9 is respectively with the cylinder of both ends of the surface on more bolts 3 and cylinder 5
End cap 51 is connected, and gasket 4 is equipped between flange 21 and barrel body end cover 51, it is ensured that vapourizing unit seals, ethylene oxide gas
Body does not leak.The tubulation 8 in cylinder can be cleared up after upper low head is dismantled, prevent tubulation 8 from blocking.
Supporting leg 13 is welded on low head 9, to support vapourizing unit.Supporting leg 13 is fixed on ground with bolt after installation
On, ensure the stability of vaporizer.
First temperature sensor 14 is installed, for measuring the temperature of hot water in cylinder 5 on cylinder 5.Ethylene oxide gas
Air outlet pipe 1 is connected with second temperature sensor 15, and second temperature sensor 15 is mounted on close into ethylene oxide sterilizer case
On the ethylene oxide pipeline of body, for measuring the temperature of ethylene oxide gas.
5 outside of cylinder is enclosed with the thermal insulation layer 6 made of heat-barrier material and is used as keeping the temperature cylinder 5, in 6 outer bread of thermal insulation layer
Protective layer 7 is covered with, to protect thermal insulation layer 6.
In the present embodiment, first by heat recirculated water valve opening before vaporization work starts, circulating hot water from water inlet pipe 12 into
Enter and outflowed back in cyclic water tank from outlet pipe 11 after being full of in cylinder 5.When the first temperature sensor 14 on cylinder 5 measures
Hot water temperature reach the temperature value of setting after, under conditions of hot water circuit is kept open ethylene oxide air supply system valve
Door, bottled ethylene oxide gas (being also likely to be gas-liquid mixture) at room temperature pass through under the entrance of ethylene oxide gas air inlet pipe 10
Diffusion is entered back into after stablizing in each tubulation 8 in end socket 9, and the heat of hot water in cylinder 5 is absorbed during by tubulation 8 and makes epoxy
Until completely vaporizing, the ethylene oxide gas after vaporization leads to the temperature rise of ethane gas again after being stablized by the concentration of upper cover 2
It crosses ethylene oxide gas air outlet pipe 1 and associated pipe and is input in sterilizer babinet with the state completely vaporized and sterilized, when
When the temperature value that second temperature sensor 15 is measured to is less than the temperature set, alarm signal is sent out, user should take measures
Improve ethylene oxide gas temperature.Just stop conveying ethylene oxide gas after aeration quantity reaches the requirement of setting, by gas cylinder
Valve is closed, and gas replenishment process terminates.
After ethylene oxide gas replenishment process, the ethylene oxide in vapourizing unit should be fully entered in sterilizer babinet,
But still there is a small amount of ethylene oxide residue in vaporizer pipeline on pipeline when valve is closed, since ethylene oxide is vaporizing
Polymerisation is had under state, polymer is firmly bonded on tube wall.Although it fills after ethylene oxide and sterilizes every time as required
After will be purged with nitrogen pipeline, but unavoidably used on pipeline with the presence of a small amount of ethylene oxide polymer
Time is grown, and polymer increases, and makes pipeline not smooth, and caliber becomes smaller, and lengthens ethylene oxide vaporization and inflationtime, influences to give birth to
Produce efficiency.It cannot ventilate when blocking serious, it is impossible to carry out sterilizing works.
In view of the above-mentioned problems, the sterilizer of 100 cubic metres, 35 cubic metres equal-specifications has used tubulation provided in this embodiment
Formula vapourizing unit, by periodically disassembling the end socket at vapourizing unit both ends, manually the method for mechanical chipping is in cylinder 5
Straight-through tubulation 8 is cleared up, and can prevent tubulation from blocking, and is ensured equipment normal use, is not influenced to produce, and extends vapourizing unit
Service life.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, it under the premise of the utility model technical principle is not departed from, can also do
Go out several improvement and modification, these improvements and modifications also should be regarded as the scope of protection of the utility model.
