[0021] To achieve this purpose, the second aspect of the utility model adopts the following technical solutions:

[0022] A deactivation system comprises high-temperature sterilization equipment and the above-mentioned discharge device, wherein the discharge device is connected to the high-temperature sterilization equipment.

[0023] As can be seen from the above, the technical solution provided by the utility model is that when it is necessary to extract the condensed water and / or steam in the inner chamber through the vacuum pump, the inner chamber discharge valve and the low-temperature discharge valve are opened. At this time, the high-temperature discharge valve is in a closed state, the vacuum pump is working, and the steam or condensed water in the inner chamber passes through the inner chamber discharge pipe, the low-temperature water inlet pipe, the heat exchanger, the vacuum pump and the low-temperature water outlet pipe in sequence, and finally enters the waste liquid collection tank.

[0025] When it is not necessary to extract the condensed water and / or steam in the inner chamber through the vacuum pump, the inner chamber discharge valve and the high temperature discharge valve are opened. At this time, the low temperature discharge valve is in a closed state, the vacuum pump does not work, and the steam or condensed water in the inner chamber passes through the inner chamber discharge pipe and the high temperature discharge pipe in sequence, and finally enters the waste liquid collection tank. At this time, the condensed water and / or steam are not cooled by the heat exchanger. Compared with the waste liquid in the waste liquid collection tank that is cooled by the heat exchanger in the prior art, the waste liquid in the waste liquid collection tank in the utility model has a higher temperature. Therefore, when heating and sterilizing the waste liquid in the waste liquid collection tank, the waste liquid only needs to increase a lower temperature to reach the sterilization temperature, reducing the heat required for heating, thereby reducing energy loss and reducing costs. The low temperature discharge valve and the high temperature discharge valve enable the inner chamber discharge pipe to be selectively connected to one or both of the low temperature water inlet pipe and the high temperature discharge pipe, so that the user can selectively discharge high temperature condensed water and / or steam or low temperature condensed water and / or steam cooled by the heat exchanger as needed, thereby ensuring that the temperature of the waste liquid in the waste liquid collection tank is not too high and heat is not wasted.

Exemplarily, the high-temperature sterilization device 1 includes an inner chamber 11 and an interlayer 12 arranged outside the inner chamber 11, and high-temperature steam can be introduced into the interlayer 12 and the inner chamber 11. The steam in the inner chamber 11 is used to sterilize medical devices, and the steam in the interlayer 12 is used to keep the inner chamber 11 warm.

[0044] The discharge device provided in this embodiment can save water and heat energy.

[0045] The discharge device provided in this embodiment includes an inactivation system and a discharge device, which includes a waste liquid collection tank 2, an acceleration component 3, a cooling component 4, a high temperature discharge component 5 and an inner chamber discharge component 6. The waste liquid collection tank 2 is used to collect waste liquid.

[0046] The acceleration component 3 includes a low-temperature discharge valve 31 and a low-temperature water inlet pipe 32, a heat exchanger 33, a vacuum pump 34 and a low-temperature water outlet pipe 35 connected in sequence. The low-temperature water outlet pipe 35 is connected to the waste liquid collection tank 2, and the low-temperature discharge valve 31 is connected to the low-temperature water inlet pipe 32.

[0047] The cooling assembly 4 includes a chilled water inlet pipe 42, a chilled water return pipe 43 and a chilled water supply member, wherein the chilled water inlet pipe 42, the heat exchanger 33, the chilled water return pipe 43 and the chilled water supply member are sequentially connected to form a circulation loop. The chilled water supply member can be any device for cooling water, such as a refrigerator.

[0048] The cooling component 4 may also include a chilled water valve, which is used to control the on-off of the chilled water inlet pipe 42 or the chilled water return pipe 43. Optionally, the chilled water valve includes a chilled water inlet valve 44 and a chilled water outlet valve 45. The chilled water inlet valve 44 is connected to the chilled water inlet pipe to control the on-off of the chilled water inlet pipe, and the chilled water outlet valve 45 is connected to the chilled water outlet pipe to control the on-off of the chilled water outlet pipe.

[0049] The high temperature discharge assembly 5 includes a high temperature discharge pipe 51 and a high temperature discharge valve 52. The outlet end of the high temperature discharge pipe 51 is connected to the waste liquid collection tank 2, and the high temperature discharge valve 52 is connected to the high temperature discharge pipe 51. The inner chamber discharge assembly 6 includes an inner chamber discharge pipe and an inner chamber discharge valve. The inner chamber discharge valve is connected to the inner chamber discharge pipe. The inlet end of the inner chamber discharge pipe is connected to the inner chamber 11. The inlet end of the high temperature discharge pipe 51 and the inlet end of the low temperature water inlet pipe 32 are both connected to the inner chamber discharge pipe and are both located downstream of the inner chamber discharge valve.

[0050] When it is necessary to extract the condensed water and / or steam in the inner chamber 11 through the vacuum pump 34, the inner chamber discharge valve and the low-temperature discharge valve 31 are opened. At this time, the high-temperature discharge valve 52 is in a closed state, and the vacuum pump 34 is working. The steam or condensed water in the inner chamber 11 passes through the inner chamber discharge pipe, the low-temperature water inlet pipe 32, the heat exchanger 33, the vacuum pump 34 and the low-temperature water outlet pipe 35 in sequence, and finally enters the waste liquid collection tank 2. The heat exchanger 33 can cool the steam and condensed water to liquefy the steam and cool the condensed water, so as not to damage the vacuum pump 34. The vacuum pump 34 can also accelerate the discharge of condensed water and / or steam.

[0051] When the vacuum pump 34 is working, the chilled water valve is opened, and the chilled water supply part provides chilled water to the chilled water inlet pipe 42. The chilled water passes through the chilled water inlet pipe 42, the heat exchanger 33, and the chilled water return pipe 43 in sequence, and finally returns to the chilled water supply part. The chilled water supply part cools the chilled water again, so that the chilled water can be recycled, which greatly reduces the amount of liquid entering the waste liquid collection tank 2 and reduces water waste. Since the channel for circulating steam or condensed water in the heat exchanger 33 is different from the channel for circulating chilled water, the chilled water will not contact the condensed water containing bacteria or viruses, and the chilled water will not be contaminated.

[0052] When it is not necessary to extract the condensed water and / or steam in the inner chamber 11 through the vacuum pump 34, the inner chamber discharge valve and the high-temperature discharge valve 52 are opened. At this time, the low-temperature discharge valve 31 is in a closed state, and the vacuum pump 34 does not work. The steam or condensed water in the inner chamber 11 passes through the inner chamber discharge pipe and the high-temperature discharge pipe 51 in turn, and finally enters the waste liquid collection tank 2. At this time, the condensed water and / or steam are not cooled by the heat exchanger 33. Compared with the waste liquid in the waste liquid collection tank 2 that has been cooled by the heat exchanger in the prior art, the waste liquid in the waste liquid collection tank 2 in this embodiment has a higher temperature. Therefore, when heating and sterilizing the waste liquid in the waste liquid collection tank 2, the waste liquid only needs to be raised to a lower temperature to reach the sterilization temperature, thereby reducing the heat required for heating, thereby reducing energy loss and reducing costs. The low-temperature discharge valve 31 and the high-temperature discharge valve 52 enable the inner chamber discharge pipe to be selectively connected to one or both of the low-temperature water inlet pipe 32 and the high-temperature discharge pipe 51, so that the user can selectively discharge high-temperature condensed water and / or steam or low-temperature condensed water and / or steam cooled by the heat exchanger 33 (steam liquefied into condensed water) as needed, thereby ensuring that the waste liquid temperature in the waste liquid collection tank 2 is not too high and that heat is not wasted.

[0053] Optionally, the low-temperature water inlet pipe 32, the high-temperature discharge pipe 51 and the inner chamber discharge pipe are made of stainless steel, and the waste liquid collection tank 2 can also be made of stainless steel.

The outlet end of the inner chamber lower drain pipe 65 is connected to the waste liquid collection tank 2. When the condensed water of the inner chamber 11 is discharged through the inner chamber lower drain pipe 65 and the inner chamber lower drain valve 66, it does not pass through the heat exchanger 33, thereby reducing heat waste.

The interlayer drain valve 72 is connected to the interlayer drain pipe 71.

The softened water valve 83 is connected to the softened water inlet pipe 81, and the softened water outlet pipe 82 is connected to the waste liquid collection tank 2. The softened water inlet pipe 81, the vacuum pump 34 and the softened water outlet pipe 82 are connected in sequence. The softened water will contact with the waste liquid in the vacuum pump 34, thereby being contaminated. The softened water is discharged into the waste liquid collection tank 2 after one use, thereby preventing bacteria and viruses from contaminating the environment.

[0065] When using the inactivation system provided in this embodiment, exemplary:

The chilled water inlet valve 44 and the chilled water outlet valve 45 are always open, and the chilled water enters the heat exchanger 33 through the chilled water inlet pipe 42 and the chilled water return pipe 43 for cooling. The low-temperature discharge water cooled by the heat exchanger 33 is discharged by the suction pressure of the vacuum pump 34, and the discharged waste liquid directly enters the waste liquid collection tank 2.

[0068] If the above two-way discharge does not require the participation of the vacuum pump 34 and only relies on the positive pressure of the inner chamber 11 for discharge, then the low-temperature discharge valve 31 is closed, the high-temperature discharge valve 52 is opened, and the discharged waste liquid directly enters the waste liquid collection tank 2.

[0069] 2. After the high-temperature steam of the interlayer 12 of the high-temperature sterilization equipment 1 passes through the interlayer drain valve 72 and the interlayer drain pipe 71, it directly enters the waste liquid collection tank 2 without cooling down, and the residual heat can provide a heat source for inactivation of the waste liquid.

[0071] 4. The high temperature of the inner chamber 11 is discharged through the inner chamber lower drain valve 66 and the inner chamber lower drain pipe 65, and directly enters the waste liquid collection tank 2 without cooling. The residual heat can provide a heat source for inactivation of the waste liquid.

[0072] 5. The vacuum pump 34 may be a water ring vacuum pump 34 , which requires softened water. The softened water enters the vacuum pump 34 through the softened water valve 83 to work, and is discharged into the waste liquid collection tank 2 together with the water cooled by the heat exchanger 33 .
