Description

Field of technology

The utility model refers to an installation for the processing of waste plant biomass, in particular waste plant biomass from the agricultural and timber industries, including wood, with a view to utilizing it as a source of energy for production and domestic use.

BACKGROUND OF THE INVENTION

As the planet's population grows and available energy sources become increasingly limited, there is a need for greater use of waste, especially from renewable sources such as plant or animal material. Although programs for the reuse and use of renewable products are becoming increasingly popular, many problems remain unresolved. These include finding compositions that are inexpensive to manufacture, easy to store and easy to transport, while being environmentally friendly. One of the rational ways to utilize waste plant mass is to convert it into briquettes and pellets, which find many applications such as combustion plants, as animal bedding, as absorbent products, for landscaping and landscaping, as well as for home heating.

Pellets are products obtained by pressing wood or agricultural waste, representing small cylinders with a length of about 2 cm and a diameter of 6 to 12 mm. Due to their low sulfur content and harmful elements, low ash content and high caloric content, these products are especially in demand in order to raise the living standards of mankind.

Installations for producing pellets from waste biomass are known, such as the installation used according to patent application US 2016/002554, which includes a heater for heating the raw material; a press for compacting the raw material and a dryer for removing residual moisture from the already compacted biomass and does not provide elements for pre-treatment of the raw material.

The objective of the utility model is to propose an installation for the processing of waste plant biomass, in particular waste plant biomass from the agricultural and timber industries, including wood, with a view to utilizing it as a source of energy for production and domestic use.

Technical essence of the utility model

In essence, the utility model refers to a plant for the processing of waste plant biomass, in particular waste plant biomass from the agricultural and timber industries, including wood, which includes sequentially located and functionally connected crushers connected on one side to a mill and another - with a buffer container for wet material; a combined dryer connected to the mill and the wet material buffer tank on the one hand and to the dry particle buffer tank and the fuel buffer tank on the other, and the dry particle buffer tank to the pellet machine connected to a cooler which from its side is connected to both the dry particle buffer tank and the packaging machine. The combined dryer, the wet buffer tank, the dry buffer tank and the fuel buffer tank are equipped with fans.

Thus constructed, the plant for processing of waste plant biomass, according to the utility model, provides an intensified process for full utilization of the waste plant biomass from the agricultural and timber industry; the resulting final product is pellets that are environmentally friendly, as no adhesives or other additives are used, their combustion does not emit harmful gases, and therefore are applicable as an environmentally friendly energy source for industrial and domestic needs.

The present utility model is illustrated by the following exemplary embodiment, without limiting its scope.

Example 1.

According to a preferred embodiment of the present utility model, the waste plant biomass processing plant shown in FIG. 1 consists of series-arranged and functionally connected elements, namely: a crusher 1 connected to a grinder 3 on the one hand and a wet material buffer vessel 7 on the other hand, which are connected to a combined dryer 2 representing a hydraulic mixer and feeding the associated dry particle buffer tank 8 and fuel buffer tank 9. The dry particle buffer tank 8 is connected to a pellet machine 4 equipped with a cooler 5, which is connected to both the packaging machine 6 and the buffer tank for dry particles 8. The combined dryer 2, the wet material buffer tank 7, the dry particle buffer tank 8 and the fuel buffer tank 9 are provided with fans 10.

Operation of the installation according to the utility model

For processing straw from grain production, the plant operates in the following sequence.

The straw is fed to the crusher 1 for shredding, after which it is fed by auger transport to the buffer container for wet material 7, and from there to the combined dryer 2, where it is dried to a humidity below 10%. After leaving the dryer 2, the raw material falls into the buffer vessel for dry particles 8 and from there - in the pellet machine 4, where they are pressed. The resulting pellets then pass through the cooler 5, which also acts as a deduster to separate dust and fine particles, the latter being returned to the dry particle buffer vessel 8 for re-feeding to the pellet machine. The quality pellets are fed by gravity to the feeder of the packaging machine 6, in which the finished product is packaged.

In cases where the plant according to the utility model is used for wood processing, the latter is subjected to pre-treatment for removal of bark and splitting and only then is fed to the crusher 1.

The installation, according to the utility model, allows processing of any type of waste plant biomass from the agricultural and timber industry, including wood and its conversion into an environmentally friendly source of energy for production and domestic needs.

The obtained final product - pellets from waste plant biomass has a calorific value of 4300-4500 Kcal / kg, ash content from 0.9 to 1.5%, humidity below 10% and extremely low content of sulfur and harmful elements.
