The reverse air bag house (rabh) is a custom-built filter, designed for cleaning gases with typically high flow rates and high temperatures. Himenviro rabh have been designed to clean emissions from various industrial processes and handle a wide range of gas volumes from 50, 000 m3hr. To more than 15, 00, 000 m3hr. Depending upon the duct characteristics, himenviro offers the most economical and efficient cleaning method to minimize pressure drop across the bag house.

HIMENVIRO has a significant amount of operating experience with large reverse gas type fabric filters for Cement Kiln and Ferro alloys Furnace lime kilns and metallurgical processes. The Reverse Air Bag House (RABH) is a custom-built filter, designed for cleaning gases with typically high flow rates and high temperatures.

HIMENVIRO RABH have been designed to clean emissions from various industrial processes and handle a wide range of gas volumes from 50, 000 m3/hr. to more than 15, 00, 000 M3/hr. Depending upon the duct characteristics, HIMENVIRO offers the most economical and efficient cleaning method to minimize pressure drop across the bag house.

The typical HIMENVIRO RABH is modular in construction, the modules being set in pairs, this construction and operation of the units not only offers control on velocity profiles, but also facilitates on-line maintenance. Each module can be isolated for inspection or maintenance by closing the inlet, outlet and reverse air damper, while other modules are in operation. The units - being custom built and voluminous - are dispatched knocked down to structural and panels.

Functional and construction features

Compact filters type ProJet smart are particularly compact bag filters with integrated fan, silencer and a cleaning control system. They are the inexpensive and easily available dust removal solution for many application areas. The function of the filters is based on the jet pulse principle. The filters are cleaned by means of the highly efficient Intensive-Filter injector system with "ideal nozzle". The Himenviro JetBus Controller is part of the scope of delivery and guarantees fully automatic cleaning. ProJet smart compact filters are characterised by their sturdiness and proven quality. The filters achieve high precipitation efficiency. Low maintenance requirement with high reliability is a decisive factor in reducing running costs. For new systems, enhancements and conversions, we develop precise recommendations to meet your specifications. The ProJet smart bag filters are produced in series. The delivery times are correspondingly short. As an experienced specialist, we offer high quality, professional consultation, and optimised process sequences.
