Description
Technical Field
The utility model relates to the field of bag dust removal, in particular to a poppet valve installation mechanism of a bag dust remover.
Background
The bag-type dust collector is a dry dust filter, and consists of an upper box body, a bag chamber, an ash discharging device, a pulse blowing ash cleaning control system and the like. The bag type dust collector is divided into two parts by a pattern plate. The upper part is called the upper tank or static air chamber and the lower part is called the bag chamber or filter chamber.
The working principle of the pulse bag-type dust collector is as follows: the dust-containing gas enters the ash bucket under the attraction force of the induced draft fan and is uniformly distributed on each filter bag after passing through the guide plate. Dust is intercepted on the outer surface of the filter bag, and gas passes through the filter bag and is discharged outside after passing through the static air chamber. Dust trapped on the outer surface of the filter bag by the bag type dust collector can cause the air permeability of the filter bag to be reduced, the resistance of the dust collector is increased continuously until the resistance reaches a set value (differential pressure control) or the filtering time reaches a set value (time control), a pulse valve which is normally in a closed state is opened for a very short period of time (about 0.1 s) under the pulse injection control of a pulse injection controller PLC, and high-pressure air instantaneously enters the injection pipe from an air bag and is sprayed into the filter bag from an injection hole at a high speed. The high velocity air flow also creates a secondary flow of air that is several times the flow of air being injected into the filter bag.
The combined action of the jet air flow and the secondary drainage ensures that the pressure inside the filter bag is rapidly increased, the filter bag is changed into a convex shape from the original concave shape, and a large reverse acceleration is generated when the deformation reaches the maximum value, and dust adsorbed on the filter bag is separated from the surface of the filter bag mainly under the action of the reverse acceleration and falls into an ash bucket, so that the resistance of the dust remover is reduced. The process of removing dust from the surface of a filter bag is known as ash removal.
The dust removing system plays a decisive role in the bag type dust collector except that the filter bag materials are properly selected. Therefore, the ash removal method is one of the characteristics of the bag filter, and is also an important ring in the operation of the bag filter.
The effect of pulse off-line deashing mode is best, and the deashing system includes: pulse jet valve, poppet valve assembly and compressed air pipeline. The ash removal process is carried out in a chamber-by-chamber mode, each chamber is separated from the other chambers by a lifting valve, the lifting valve falls down during ash removal, and the lifting valve rises during normal operation. The ash removal in each room is carried out in a row, and each time the pulse valve acts, the ash removal is obtained by a row of filter bags. The pulse valve acts sequentially according to the set time interval and sequence until one cycle is completed. The whole dust remover completes one dust removing period.
The poppet valve cylinder of the prior art is typically mounted directly on the top surface of the static air chamber, see fig. 1, so that the poppet valve is in a dropped state and the cylinder shaft of the poppet valve cylinder is completely exposed to the static air chamber during normal operation of the dust collector. Because the treated boiler flue gas has corrosiveness, the cylinder shaft is easy to corrode and rust, so that the poppet valve cylinder is damaged and cannot be used, the whole poppet valve cylinder needs to be replaced frequently, waste is caused, and the cost is increased.
