1 T/H Wood Pellet Production Line In Spain

In order to meet the market demand for biomass pellets, the client, a furniture factory, used its idle factory buildings to purchase 8 equipment such as pellet machines, belt conveyors, and air compressors to build a new biomass pellet production project. The wood pellet production line in Spain project has a total of 5 employees, working 8 hours a day, and 300 operating days per year.

The project invested 80,000 USD and covers an area of about 500 square meters. After the project is officially put into production, it will have an annual production capacity of 2,400 tons of biomass molded fuel. The main project and product plan of the proposed project are shown in the table below:

The consumption of raw materials for this wood pellet production line in Spain project is as follows:

The main equipment of this wood pellet production line in Spain project is as follows:

According to the wood pellet production line in Spain  project composition and layout principles, combined with the internal and external constraints of the project, considering that the factory is close to the residents on the northeast side, the finished product warehouse is set up on the north side of the factory, and the equipment that generates more noise is arranged in the middle of the factory.

This layout is more reasonable and ensures that the high-noise equipment workshop is more than 50 meters away from the residents.

The wood biomass pellet production line project is located in Spain, so the environmental protection standards are relatively strict. Since the odor of the raw materials has little impact on the surrounding atmospheric environment after being diffused through the atmosphere, this project mainly considers the impact of dust on the surrounding atmospheric environment.

For the process dust generated during the processing, a cyclone separator and a bag dust removal system are set up in the section where pollutants are generated.

The cyclone separator is a dust collector, which is composed of two inner and outer cylinders, a cone cylinder and an air inlet. The ash outlet, the inner and outer cylinders and the ash outlet are located on the same axis.

The dust removal principle of the cyclone separator is that the dust-laden air enters through the air inlet on the upper part of the outer cylinder at a high speed, and then rotates in a spiral shape from top to bottom between the inner and outer cylinders and the cone.

During the rotation, the dust particles are thrown to the inner wall of the outer cylinder under the action of a large centrifugal force, and collide and rub against the wall surface and gradually lose speed, and then fall along the cylinder wall to the cone part under the action of gravity, and then discharged from the bottom ash outlet.

When the airflow approaches the lower end of the cone, the air cannot flow out from the bottom due to the air-closing device installed at the outlet, and begins to reverse and rise, and then is discharged through the inner cylinder.

Bag dust collector is a dry dust removal device, which is suitable for capturing fine, dry non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas.

When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

The dust removal efficiency of the bag filter is higher than that of the cyclone separator. The bag filter can be connected after the cyclone separator to play a secondary filtering role. The dust removal efficiency of the combined treatment device is more than 99%.

The treated exhaust gas is concentrated and discharged through a 15-meter-high exhaust pipe. The emission concentration is 31.25mg/m3, which meets the comprehensive emission standards of atmospheric pollutants and has little impact on the surrounding atmospheric environment.

At the same time, our engineers also recommend that customers close the workshop. After taking the above measures, the dust generated by this wood pellet production line in Spain project is expected to have little impact on the surrounding environment, and this treatment measure is feasible.

In the actual production process, it is recommended that the customer take the following measures to reduce waste gas emissions:

• Unorganized dust will be generated during the granulation process. It is recommended to install exhaust fans in the workshop to strengthen workshop ventilation;
• During the transportation of raw materials and finished products in the factory area, vehicles should limit speed and standardize transportation;
• During the production process, operators should be trained and managed to reduce the unorganized emission of waste gas caused by human factors. The above measures can effectively reduce the impact of unorganized emission of waste gas on the atmospheric environment.

In terms of noise control, the following measures are mainly planned to be taken:

1. Configure and select low-noise and high-quality equipment for customers to reduce the noise intensity of equipment from the sound source.
2. In terms of factory functions and equipment layout in the workshop, the design principle of separating noise and quiet and reasonable layout is adopted. Noise-generating equipment is arranged in the middle of the factory building to reduce its sound energy radiation to the factory boundary and environmental sensitive points.
3. For equipment with high noise, sound insulation and noise elimination are adopted. For equipment that is prone to vibration, the base is equipped with vibration isolation pads, shock absorbers and other measures.

The domestic waste generated by the wood pellet production line in Spain project will be regularly cleared by the sanitation department, and the screened wood blocks will be collected and sold. The solid waste generated by the project can be effectively disposed of, which has little impact on the project.

The organized dust of the wood biomass pellet plant project is discharged after being treated by the cyclone separator + dust removal system. The unorganized dust is expected to meet the standards after ventilation, which will not significantly affect the ambient air quality in the area. At the same time, it is recommended to close the workshop.

The project has no process wastewater discharge, and domestic sewage is treated in septic tanks and used as organic fertilizer, which does not affect the use function of regional surface water bodies and creates good economic and environmental benefits.

The noise generated by the wood pellet production line in Spain project can achieve the expected control effect after reasonable layout, vibration-proof foundation, building isolation, sound insulation barrier, greening noise reduction and distance attenuation. It is expected that the noise will have little impact on the factory boundary noise.

The solid waste of the project is mainly domestic garbage and waste wood blocks. Domestic garbage is regularly cleared by the sanitation department, and wood blocks are collected and sold for proper treatment.

Currently, in Spanish home furnishing stores, a 15-kilogram bag of wood pellets costs about 7 euros (1 euro is about 7.44 yuan), and the average burning time is expected to be up to 15 hours, enough to provide nearly 3 days of heating for an average family using a pellet stove. For Europeans who are suffering from rising energy prices, the hot sales of wood pellet fuel are understandable.

Wood pellet fuel is a small pellet about two or three centimeters long, made of sawdust, shavings and other wood scraps. As a kind of biofuel, it is not only suitable for industrial production scenarios, but also for small businesses such as bakeries, restaurants, and hotels. In recent years, it has gradually entered ordinary households and become one of the alternative fuels for heating.

As a biofuel, wood pellet fuel has begun to enter more people's field of vision. A study shows that compared with natural gas, using wood pellet fuel for heating can save about 20% of the cost; compared with electricity, it can save up to 57% of the cost.
