it should be noted that the pressure vessel is provided with a valve (not shown) to allow connection to the outside. When the pressure of the whole purification system is insufficient, the external container can supplement clean gas to the pressure container through the valve so as to improve the pressure of the purification system; when the pressure of the whole purification system is too high, the pressure container can release the gas circulated by purification to the external container through a valve so as to reduce the pressure of the purification system. However, because the double-layer sealing box has better sealing performance, the double-layer sealing box and the purification system have little gas exchange with the outside in a short period, namely, excessive new gas cannot enter the sealing box and the purification system in a short period to increase the pressure of the sealing box and the purification system, and excessive gas cannot flow outwards to reduce the pressure of the sealing box and the purification system. The valve is only used when the seal box needs to compensate the pressure of the whole system or the pressure of the whole system after long-term purification circulation and work.
An empirical formula obtained according to actual test data: t isf∝2ΔP3+1000S +2T +0.15v, the toxic substance leakage amount TfThe method has the advantages that the method is in positive correlation with the inside and outside pressure difference delta P, the welding seam defect area S, the gas temperature T and the average gas flow velocity v at the welding seam defect, the welding seam defect area is a fixed value after the sealing box is machined, the gas temperature and the average gas flow velocity at the welding seam defect have small influence on the toxic substance leakage amount, the inside and outside pressure difference is a cubic term, the toxic substance leakage amount can be effectively reduced only by maintaining the inside and outside pressure difference at the negative pressure difference, the sealing box body can deform if the negative pressure difference is not too large, the sealing performance is reduced, and therefore according to actual test experience, the inside and outside pressure difference is controlled to be-1000 Pa, and good sealing performance can be obtained.
Step 3, judging whether toxic and harmful solids or liquid are left in the sealed box, if so, driving the cleaning device 3 in the sealed box by a motor to move the cleaning box 3.4 to each position in the sealed box, sucking the solid and liquid residues by using different cleaning heads 3.5, storing the sucked residues in the cleaning box 3.4, and after cleaning is finished, returning the cleaning box 3.4 to the corner position and closing the cleaning heads 3.5 to seal the residues;
step 4, carrying out the same purification cycle on the top 1.1, the bottom 1.2, the long side 1.3 and the short side 1.4, and stopping the purification cycle when the harmful substance concentration sensor detects that the content of the toxic and harmful gas meets the preset requirement; when the purge cycle is stopped, the top intake control valve, the bottom intake control valve, the long side intake control valve, and the short side intake control valve are closed, the top exhaust control valve, the bottom exhaust control valve, the long side exhaust control valve, and the short side exhaust control valve are kept open, and the air pump pumps and keeps the internal pressures of the top portion 1.1, the bottom portion 1.2, the long side portion 1.3, and the short side portion 1.4 lower than the atmospheric pressure and lower than the pressure in the sealed tank;
if the air pump is installed again in a short time after short-distance transportation or disassembly, the air pump is disconnected from the air inlet control valve and the air pumping control valve in the box, the relative negative pressure of each part is kept by closing the air inlet control valve and the air pumping control valve so as to save energy, when the sensor detects that the relative negative pressure of the top part 1.1, the bottom part 1.2, the long side part 1.3 and the short side part 1.4 is insufficient, the air pumping control valve and the air pump are communicated, and the relative negative pressure is kept in a specified range by the air pump; if long-distance transportation is needed or the air pump is not installed for a long time after disassembly, the air pump is communicated all the time, and the relative negative pressure of each part is kept through the air pump;
step 5, after the top 1.1, the bottom 1.2, the long side 1.3 and the short side 1.4 keep relative negative pressure, the pressure in the sealing box is restored to normal pressure by an air pump, and then the parts are detached;
step 6, after the disassembly is finished, the top 1.1, the bottom 1.2, the long side 1.3, the short side 1.4 and the cleaning device 3 in the sealed box are separately transported, and in the transportation process, the relative negative pressure in the top 1.1, the bottom 1.2, the long side 1.3 and the short side 1.4 is always kept within a specified range; and after the transportation to the destination, the installation is carried out according to the installation sequence.
The mounting sequence of each part is opposite to the dismounting sequence.
