Bag filter fire and explosion precautions

Bag filter fire and explosion precautions

Introduction: The bag dust collector is currently the most widely used dust removal equipment in the dust removal industry. In some special industries, the dust is flammable and explosive. Therefore, we need to carry out some special treatment on the bag filter to achieve the purpose of fire prevention and explosion protection. City Zhicheng Dedusting Equipment Co., Ltd. will explain the precautions of fireproof and explosion protection of bag filter.

1. If the gas to be treated is high-temperature gas, use a high-temperature, non-flammable dust filter bag.

2. When dealing with flammable and explosive dust, dust filter bags use high temperature or non-flammable materials.

3. For dust removal systems where there is a risk of burning or explosion dust and flammable debris, use a dust collector that does not generate sparks and static electricity.

4. Dust that can form an explosive mixture when in contact with water. Wet dust removal equipment cannot be used.

5. Set a combustion chamber or Mars trap in front of the bag filter to completely burn unburned dust and gas or trap Mars.

6. The use of explosion-proof motor equipment, the treatment of combustible gases must be installed alarm and automatic parking system.

7. Pay attention to the cleanliness of the workshop and prevent the accumulation of dust in the workshop and dust inside the dust collector so as to avoid spontaneous combustion and explosion of the dust.

8. Set explosion-proof pressure relief vents at the necessary places of the dust removal system to prevent explosions due to excessive pressure. Install lightning protection measures outdoors and install lightning rods.

9. To prevent the sundries in the airflow from hitting the impeller and the casing, sparks must be installed behind the dust collector.

10. The use of measures to prevent static electricity from accumulating for the bag filter shall be added. Each part shall be grounded with a conductive material, or a conductive fiber may be added during the manufacture of the filter material.

2 Ton Electric Stacker

1. Multifunctional handle
The multifunctional handle is imported from Germany. It has integrated control functions including a speed button, horn button, emergency reversing button and lifting button. The handle has an emergency reversing button which can effectively protect the operators from being hurt in accident involving falling items. The handle can realize braking both in vertical and horizontal position. The human-machine design is quite safe and the operation is more comfortable.

2. Strong power
This stacker adopts high efficiency motor which can be precisely controlled and the output power is strong. The turning control can be optionally equipped with EPS. It can help the driver with turning by using electronic control device to produce auxiliary power of relative level and direction according to the torque signal and speed signal. So the operation of the driver can be more convenient and precise and the movement can be more stable and reliable.

3.Superior gradeability
The powerful motor and 5 wheel stacker structure can provide superior stability and gradeability, so that the truck can have sufficient gradeability when it is fully loaded.

4. Buffered pedal
The foldable pedal can save space when the stacker is not in use. It can also effectively protect the drivers from being effected by the bumping and give feedback to the driver with the road condition.

5. Dual balance wheel device
This stacker is equipped with a dual balance wheel so that it can overcome roadblocks easier and the running can be more stable.

6. Emergency power-off switch
The power can be rapidly cut off in emergency to ensure safety.


Electric Stacker, or walkie stacker, is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.


Compared with the traditional manual stacking, Zowell full electric stacker maintains great advantages in safety, efficiency and cost. In addition to durability and accuracy both outside and inside, Zowell XE electric stackers are also equipped with mast with clear view, double speed and lateral vertical moving switch, which are valuable when working in limited space.

The standard load capacity of XE series ranges from 1 ton to 2 tons, two driving modes: walking and standing driving. If you need bigger capacity or other customized options such as rod, low mast, grabbling frame, please contact us so that we can provide you best solution with professional knowledge.
