Clean­ing con­trol HE 5750

Auto­matic mon­i­tor­ing of valve and fil­ter func­tions

Espe­cially large fil­ter plants with sev­eral hun­dred clean­ing valves and many thou­sands of fil­ter bags, such as those found in waste incin­er­a­tion plants and cement works, should have a high degree of auto­mated mon­i­tor­ing processes to ensure that the plant is always fully func­tional.

For this rea­son, HESCH has inte­grated auto­matic hose rup­ture mon­i­tor­ing into the HE 5750 clean­ing con­trol sys­tem in addi­tion to exten­sive mon­i­tor­ing of the clean­ing valve func­tion. For this pur­pose, only one cen­tral dust sen­sor is option­ally required, which mounted in the clean gas duct at the fil­ter out­let, mon­i­tors the dust load of all cham­bers.

Old tech­nol­ogy out – new tech­nol­ogy in

Bring your plant up to date with the HE 5750 and sus­tain­ably reduce energy con­sump­tion.

The sup­port pro­gram of the Ger­man Fed­eral Office of Eco­nom­ics and Export Con­trol(BAFA) and the Kred­i­tanstalt für Wieder­auf­bau (KfW) pro­vides large indus­trial com­pa­nies with 30% fund­ing* for energy effi­ciency improve­ments.

Exam­ple cal­cu­la­tion:

By opti­miz­ing the con­trol sys­tem, oper­a­tors of dust col­lec­tion sys­tems can reduce power con­sump­tion by about 10 % when using a 500-kilo­watt suc­tion hoist. At a kW price of € 0.08, they save around € 35,000 in energy costs per year.

Pre-pres­sure con­trol: new fea­ture enables energy costs to be reduced

Sav­ing energy is even more impor­tant today than ever before, due to recent high elec­tric­ity price increases. HESCH has devel­oped an energy-sav­ing func­tion for oper­a­tors of large fil­ter sys­tems.

The new inlet pres­sure con­trol opti­mizes the clean­ing pres­sure. The inlet pres­sure con­trol ensures that only as much com­pressed air is deliv­ered as is required for clean­ing the fil­ter. The con­sump­tion of expen­sive com­pressed air is reduced. In addi­tion, the upstream pres­sure con­trol also has a pos­i­tive effect on the ser­vice life of the fil­ter media, since the fil­ter ele­ments are sub­jected to com­pressed air more gen­tly than before. This lower load increases the ser­vice life of the fil­ter ele­ments.

The HE 5750 reports the exact posi­tion of the defec­tive fil­ter bag.

Accu­rate hose rup­ture local­iza­tion

If one of three freely defined limit val­ues of the dust load is exceeded, the con­trol sys­tem auto­mat­i­cally assigns this event to the respec­tive cham­ber and trig­gers the cor­re­spond­ing reac­tion (e.g. an error mes­sage, an alarm or the shut­down of the sys­tem).

In this way, not only is fault-free oper­a­tion guar­an­teed at all times, but in the event of a hose rup­ture, imme­di­ately a mes­sage is also gen­er­ated with the exact posi­tion of the dam­aged hose row.

This con­sid­er­ably min­i­mizes the time required to locate a defec­tive fil­ter bag and thus increases the avail­abil­ity and effi­ciency of the sys­tem.
