Embodiment 1: carrying out the parameter comparison of 6 structure of this structure and conventional exhaust blower, and the experiment condition of setting is as follows.
1, exhausting test flume surface area: 1.5*0.8m
2, slot two sides fan housing 22: 6 structure of exhaust blower of traditional slit-aperture type fan housing 22 and this structure
3, blower 6: exhaust air rate 2456m3/h, wind pressure 1100Pa
4, chimney 7 exports: diameter 315mm.
5, tank liquor: 75 degree of -85 degree hot water is tested
Following table is the air draught parameter lookup table of traditional slit-aperture type fan housing 22 and 6 structure of exhaust blower of this structure.
As can be seen from the above table, traditional fan housing 22, blower 6 are chronically at the running at high speed under state of 50HZ, solution
1 liquid level of slot still has many steam and exhaust gas to overflow, and causes working environment moist, there are security risk, and 6 energy consumption of blower
Greatly, not environmentally, using after this structure, the air draft wind speed of chimney 7 is reduced, in the state of not adding turnover panel 24,1 surface of solution tank
Steam and exhaust gas be inhaled into from air inlet 222, the frequency of blower 6 is reduced to 25HZ and 10HZ in time by No leakage, still without
Leakage, after increasing turnover panel 24, the frequency of blower 6 is reduced in the state of 8HZ, the upper surface of solution tank 1 still without steam or
Exhaust gas leakage, it can thus be seen that this structure only needs blower 6 to operate under lower frequency, so that it may realize zero leakage of exhaust gas,
It is more energy-saving and environmentally friendly, and gas sampling effect is obvious.

So that exhaust gas spilling is matched with air draft component 2, guarantee the air draught effect of different conditions, about 8 plating piece is set in PLC system and is risen
The condition of movement drops, while PLC can control automatic open-close of the air draft component 2 under different conditions, so that air draft component 2 is opened
, it can be achieved that the oscilaltion campaign of plating piece 8 under state, under closed state, Exhaust assembly 2 covers the upper end of solution tank 1,
Exhaust leak is avoided, the quick collection of exhaust gas is conducive to, when Exhaust assembly 2 is closed, PLC controls blower 6 and works, so that exhaust gas
Wind chamber 221 is entered by air inlet 222, then into single slot air duct 3, main air duct 5 is entered finally into, eventually by chimney
7 discharges, when technological parameter requires slot cover closure, PLC control Electric air valve 4 and blower 6 are in low energy consumption state and can expire
Foot requires, and when technological parameter requires slot cover to open, according to the quantity of air inlet 222 and the maximum quantity of wind of setting, i.e., PLC is controlled
When adjustment Electric air valve 4 or blower 6 guarantee exhaust air rate, effectively avoid exhaust leak, effect is good, in reality production, because of slot
Covering most of process time can be in close state, and reduce to the gross demand of blower 6, and blower 6 is under low frequency state, is saved
Effective discharge of exhaust gas can be realized in power supply.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
