The problem of dehumidification is solved by the way of external pipeline, which ensures that the humidity in the sterilization process is controllable and avoids the risk of condensation.

[0038] The sterilization process of the hydrogen peroxide sterilization equipment is divided into four stages:

[0039] The first stage: the dehumidification stage, the hydrogen peroxide sterilization equipment starts the dehumidification function, dehumidifies the environment, and reaches the set value Rh1 (generally 60%) to start the second step;

[0040] The second stage: the filling stage, liquid hydrogen peroxide (hydrogen peroxide) is injected into the evaporator, and VHP gas is injected at a speed of V1 into the sterile workshop, and after reaching the set time T1, the third step is started;

The hydrogen peroxide sterilization equipment sprays only gas, avoiding the condensation problem caused by high humidity and corrosion.

[0044] As shown in Figure 5 The application process of the utility model is as follows:

[0045] a) Use the air conditioning system to dehumidify the sterilization space, so that the relative humidity Rh reaches below the set value Rh1 (generally 60%), stop the operation of the air conditioning system, and close the valves of the return air, fresh air and exhaust air;

[0050] f) Detect the real-time relative humidity Rh in the environment, if the relative humidity Rh reaches the set value Rh1 (generally 60%) at this time, go to the next step;

[0051] g) Injecting hydrogen peroxide into the preheated evaporator at a speed of V1, and setting the duration as t1, and the hydrogen peroxide is evaporated instantaneously to generate VHP gas, which is sprayed into the space to be sterilized;

[0052] h) During the t1 period, the hydrogen peroxide sterilization device always detects the relative humidity Rh of the environment, and if the relative humidity Rh is greater than or equal to Rh0 (generally 90%), the injection of hydrogen peroxide is stopped, and the process returns to step f to restart. If the relative humidity Rh is always less than Rh0 (generally 90%) in this step, the process proceeds to the next step.

[0053] i) The injection amount of liquid hydrogen peroxide is changed to V2, and the duration is t2;

[0054] j) During the t2 period, the relative humidity Rh of the environment is always detected, and if the relative humidity Rh is greater than or equal to Rh0 (generally 90%), the injection of hydrogen peroxide is stopped, and the process returns to step f to restart. If the relative humidity Rh is always less than Rh0 (generally 90%) in this step, the process proceeds to the next step.

[0055] k) The injection is stopped after the time reaches the set value t2;

[0056] l) The dehumidification function is kept on for a duration of t3;

[0057] m) After the duration t3 is reached, all functions are stopped;

[0058] n) The sterilization process is completed.

[0059] Generally, the values of the above parameters are as follows:

[0060] Rh0: 90%;

[0061] Rh1: 60%;

[0062] V2=0.6V1;

[0063] t1, t2, t3 are determined according to different processes.
