According to the 99/92/EC ATEX 137 Directive, manufacturer

carried out the classification of the internal and external zones,

connected with the explosion hazard during the operation

of the filtering unit.

In the Fig. No.1 is presented the classification of the internal

zones. The chamber of filters and the hopper chamber along

with the waste container have been specified as zone 20/21,

because in these areas always and in long periods potentially

explosive atmosphere occurs.

Whereas, the regeneration chamber is classified as zone 22,

because the dust occurs in this area sporadically, in case of

failures consisting in damage of the cartridge filter or the filter

mounting.

External zones can be created:



while opening the inspection doors,



during the emptying the waste container.

They have been classified as zone 22.

STRUCTURE ADN FUNCTION

5.1 Structure

BIG-12000/Ex filtering unit consists of three functional assemblies:



Regeneration chamber, being the upper part of the device, where are located outlets from the cartridge filters and

Venturi Orifices. Outside the regeneration chamber is installed the compressed air installation, consisting of:

–

compressed air tank –constructed for operational pressure not exceeding 0,8 MPa, the tank meets the re-

quirements of the European Union Directive 87/404/EEG and 90/488/EEG;

–

four electromagnetic valves of diameter 1”½, designed for regeneration of the cartridge filters, these valves

meet the requirements of directives: ATEX 94/9/EC and EMC 2014/30/EC;



Chamber of filters –forms the middle part of the filtering unit and contains the cartridge filters. On the chamber

housing is located the inspection door, (for filter replacement) and a decompression panel lowering the pressure

in case of potential explosion. Outside the chamber is installed a micro-controller –to activate the electromagnetic

valves, (described in details in Section 7);



Supporting construction along with the hopper chamber. Underneath the hopper chamber is placed a self-loading

funnel for dust / waste and a cell feeder –providing a continuous dust discharging and its loading into the transport

container or into the discharge ducting. Discharge of the accumulated dust ought to be carried out by operator.

Fig. No.2 –BIG-12000-/Ex –Structure and dimensions

BIG-12000/Ex filtering unit is served by an Ex execution fan (as additional equipment upon separate order). To

control the device is applied a switchgear, which should be installed outside (beyond)the zone of

explosion hazard. Detailed description can be found in Section 7 of the present Use and Maintenance Manual.

CAUTION:The switchgear is delivered upon separate order.

5.2 Function

BIG-12000/Ex filtering unit provides separation of the air containing dry dust fraction. The dust laden air is guided

to the chamber of filters. Here, in the decompression process and because of the flow velocity reduction, larger

particles of dust are extracted into the hopper chamber, and subsequently they fall into the waste container.

Precise dust cleaning proceeds while the air flows through the cartridge filters. In the Fig. No.3 is presented a run

diagram of the air flow through the filtering unit. As the dust accumulates on the operational surface of the cartridge

filters, this reduces the air flow intensity. To limit this disturbance, the device is equipped with a continuous

regeneration system of the filters. The impulses of compressed air (directed into the cartridge filters) strike off the

dust particles. The cleaning air is supplied from the compressed air tank, through the electromagnetic valves that

are operated by the micro-controller (as in details described in Section No.7).

In the Fig. No.4 is illustrated a schematic diagram of regeneration of the cartridge filters.

ASSEMBLY AND STARTUP

6.1 Description of mounting

Before the assembly of the device in the place of use, check if the device is complete, and if it is not damaged, or

there are indentations, etc. The appliance is delivered in two assemblies, so it should be installed by means of

adequate lifting devices and by a specialised assembly team.

First, put the supporting structure with the hopper chamber. The supporting frame should be levelled and its legs

fastened firmly to the floor. Having installed the first assembly, put the chamber of filters (with the fixed to it

regeneration chamber) on it. Handle with care, as the assembly is of large dimensions. At the upper part of the

regeneration chamber are installed lifting hooks (for lifting and positioning during the transport and assembly

activities).

After the chamber of filters is connected with the supporting structure, seal up the join surface with “silicone” and

screw it up thoroughly with bolts. The screws, bolts and “silicone” are delivered by manufacturer along with the

device.

The compressed air tank and the electromagnetic valves are delivered to the operator in completely assembled

state. Having installed the device, connect it to the external compressed air installation of 0,6 0,8 MPa. The

pressure air must not contain pollutants, oil and humidity.

The connection must be equipped with a cut-off valve, air filter and a dewaterer. These elements are not

delivered along with the device. The nominal diameter of the compressed air connection (for the device of 16

cartridge filters and at the nominal diameter of the compressed air tank of 8”) should be 1”1/2.

6.2 Start-up

Upon first operation of the compressed air installation (of the device), check if the connected part of the

compressed air system is sufficiently cleaned of the metal particles, raspings, rust, etc., because the membrane

of the electromagnetic valves would get damaged. If in the first stage of start-up there is not enough air flow

intensity (in the system) –this means the valves are not tight enough. Shut the cut-off valve in the supply of the

compressed air tank. Wait until the air pressure in the system reaches 0,6 0,8 MPa, and then quickly open the

cut-off valve.

Connect the electrical system, power supply and the control units –strictly according to the enclosed Connection

Diagram Fig. No.6, 7 and 8. As the control system is very complicated, any activity of device connection/energizing

must be carried out by an authorised installing team with qualifications. The filtering unit and the fan should be

connected to the equilibrating grounding profile.

Connect the motor with reference to the adequate data placed on the nominal data plate and in conformity with

the Connection Diagram on the cover of the terminal box (fastened to the motor).

Switchgear A1 should be mounted in area, beyond the explosion hazard zone.
