A precision voltage control circuit applicable to a PWM (Pulse Width Modulation) circuit can offer CCFL (Cold Cathode Fluorescent Lamp) or EEFL (External Electrode Fluorescent Lamp) tubes a stable high frequency voltage or current, so that each CCFL or EEFL tube can get an appropriate compensation current and an optimal emitting efficiency and enhance its emitting quality. The circuit also has an overload current, low current, and overload voltage and low voltage protective circuit to protect the CCFL or EEFL tubes from being injured. The circuit can also be applied to the TFT LCD TV or other large LCD panels, and develops the best display effect of each LCD tube.

The invention relates to the field of smoke treatment devices, in particular to a dehydrating tower provided with an anti-blocking plug. The dewatering tower comprises a fixed sleeve, a tower body, adehydrating structure, a smoke discharging structure, a sealing structure, a fixing structure, an anti-blocking structure and an anti-explosion structure. Since the dehydrating structure is arranged inside the tower body, smoke with high humidity and low temperature can be subjected to inflow dehydrating treatment, moisture and harmful tiny substances in the smoke can be removed, and the smoke discharging quality is improved beneficially; by arranging the smoke discharging structure outside the tower body, natural wind energy can be effectively utilized, the smoke discharging efficiency of a smoke outlet pipeline is improved, fuel combustion is more sufficient, and therefore waste of resources is reduced; during work of the smoke discharging structure, the anti-blocking structure can be driven to work simultaneously; through the arrangement of the anti-blocking structure, soot which adheres to the side wall inside the tower body can be cleared up in time; and the work of the anti-blocking structure can perform reaction on the smoke discharging structure, so that the working efficiency of the smoke discharging structure is higher.
