Storaging silo PSVC.14.60.150

The polygonal storage hopper with a filter section is designed to clean polluted air with a capacity of 20,000 m3/h and from woodworking and furniture enterprises with the accumulation of waste in the amount of 60 m3 for further combustion. It is made of galvanized panels 2.5-4 mm thick. The design of the bunker allows you to unload sawdust both in a big bag, and on vehicles or in a bunker of a solid fuel boiler.

Installations of the current series are recommended for use in woodworking and furniture industries.

Hopper storage with filter unit PSVC.14.60.150 is equipped with a filter section on bag filters made of antistatic polyester with a capacity of 0000 m3/h with filter regeneration by shaking.

– filtering elements made of antistatic polyester with a diameter of 215 mm, a length of 1500 mm and a density of 500g/m2 allow you to purify the air with a dust concentration at the outlet of less than 10mg/m3;

– cleaning efficiency – 99.9% of solid particles larger than 10 microns;

– it is necessary to carry out cleaning at least once every 8 hours;

– high dust collection efficiency;

For this equipment, unloading is possible in:

– big run;

– automobile;

– supply of auxiliary equipment, such as solid fuel boilers, briquettes, pellet lines.

Principle of operation: (diagram of operation of the installation with air return)

Polluted air containing waste particles from the production process is sucked in and transported to the filter section through the air duct system. Polluted air enters the storage hopper, where heavy particles fall into the accumulation compartment, and small light particles fall on the inside of antistatic bag filters with a density of 500g/m2. Where they linger on the inner specially treated surface.

The purified air passes through the filter surface and returns to the production room with minimal temperature loss. The filter unit performs fine filtration of polluted air, which allows the return of purified air to the workshop. The filter unit is equipped with a filter shaking system. The accumulated dust is knocked off the treated inner side of the filter and enters the storage hopper.

Such a cleaning system allows you to provide:

1. Efficient operation of the equipment during the whole working hour.
2. Cleaning filters from sawdust, pellets, tongs and other waste from woodworking furniture machines.

Filter antistatic moisture-oil repellent

Bag filters are used for air purification in the vast majority of industrial enterprises that emit dust and gas flows into the atmosphere, such as woodworking and metallurgical plants, cement manufacturers, asphalt plants, power plants, waste incinerators, tobacco factories, and chemical plants.

Today bag filters are the most widespread effective and economic element for the filtering installations in the world.

In the vast majority of industries, bag filters consistently provide high levels of dust collection performance with the necessary hydro-mechanical resistance and reliability.

During the operation of fabric filters, a gradual layering of dust occurs in the pores of the filter material, as well as on its surface. With an increase in the volume of dust, the hydromechanical resistance of the material also increases. As a result, clogging of the pores and the filter surface, the filter performance will decrease and therefore the filter will not be able to pass gas. Therefore, in order for the filter to be in working condition, it is necessary to regularly remove dust from the pores of the filter material.

The process of dumping part of the dust layer in fabric filters is called regeneration, thus restoring the initial properties of the filter material.

Filter block cleaning system

The cleaning system of the filter unit includes an explosion-proof vibration-shaking mechanism that operates after a period of time set by the controller, which is set depending on the dust fraction. After the unit is turned off, a cleaning cycle of all filters takes place. The whole system ensures the cleaning of the filters and keeps the filter in working order during the whole working time.

Security systems:

The unit is equipped with three passive safety systems:

Blast panels act as overpressure relief devices and constitute an ATEX protection system. Necessary to prevent and reduce the risk of explosions, in accordance with the requirements of Directive 94/9/EC – ATEX

Blast Panels – This safety system consists of a rectangular-shaped composite membrane that consists of one or more metal sections with through slots of the sealing element. Mounted between rectangular flanges with a smooth sealing surface. Used in aspiration systems to protect bag filters. Works in tension, pressure acts on a flat or concave surface, excellent for working at the lowest pressure and static loads. Works in thousandths of a second without the formation of metal fragments.

– The fire extinguishing system consists of a dry pipe with a number of nozzles located in the filter unit. The system is connected to the company’s water supply system. In case of detection of ignition, smoke in the installation, it is necessary to open the water supply valve and the nozzles located inside the filter unit will supply water and extinguish the combustion inside the installation.

– fire-retardant with a fusible insert.

The valve prevents fire from entering the production room through the air return system in case of an emergency. When the temperature in the flow of clean air entering the room after filtration rises to 70 ° C due to the return of air, a mechanism is activated that closes the valve and prevents smoke or fire from entering the production room.

Hopper unloading system (cone)

The system for unloading from the storage hopper is based on the principle of turning sawdust and feeding material into the unloading window. This design provides wear resistance and durability of the tedding system. During operation, sawdust falls to the bottom of the hopper and is unloaded down due to the cone and the design of the tedding system, 100% unloading of material is ensured without hanging zones and waste caking zones. This ensures a uniform supply of material to the dispenser valve, which is especially important for further transportation of waste by pneumatic transport.

Installation maintenance

The design of the PSVC.14.60.150 accumulator hopper is designed in such a way that when servicing the cleaning system or the filter unit, all work is carried out in a clean area. For safe work at height, the unit is equipped with ladders and platforms with a fence. The fans are placed on the foundation for easy maintenance.
