SILO STRUCTURE FOR BIOMASS

According to the present invention, since the cover mounted on the explosion-proof opening is made of a transparent synthetic resin material, the efficiency of mining to the storage space formed between the outer walls can be greatly improved, and as a result, the storage space can be made brighter. If necessary, it is possible to more easily replace and maintain the supply, etc. Furthermore, due to the inclined portion of the outer wall inclined downward to the inside of the outer wall at the lower inner periphery, the durability of the lower part of the outer wall can be further improved. It also relates to a structure of biomass silos in which a greater amount of biomass can be stored in the storage space.

Generally, in order to cope with the United Nations Framework Convention on Climate Change, cogeneration of wood obtained through natural or timber that is naturally discarded in nature, such as Sweden and Austria, which are rich in forest resources, It is actively used as a fuel for power generation.

In addition, in the UK, wood, reeds, and corn stalks are actively used as cogeneration fuels. In Korea, wood is used as a fuel made of chips and currently used as cogeneration fuels in Seodaegu Industrial Complex.

In addition, as Kyoto's sentiment was officially entered into force in February 2005, countries around the world are striving to develop and disseminate renewable energy, a fundamental measure to reduce greenhouse gas emissions.

Leading industrial developed countries in Europe have been promoting renewable energy commercialization policies since the early 1990s, accounting for up to 50% of thermal energy demand in biomass combustion systems using biomass.

Wood biomass woodchips contain ash content of 3 ~ 5wt%, but there is no technical problem to use them as fuel, and their use increases every day because there is no need for additional drying process because of low moisture content. That's the trend.

On the other hand, the biomass silo of the unit of the biomass combustion system, the bottom plate, a cylindrical outer wall vertically formed on the upper portion of the bottom plate, a roof formed on the upper portion of the outer wall, the waste wood formed between the outer wall A storage unit including a storage space for storing biomass including chips, waste plastic chips, and the like;

And a supply unit provided on the bottom plate of the storage unit so as to be rotated forward and backward to supply the biomass stored in the storage space in a downward direction of the storage space.

The biomass supplied to the lower direction of the storage space by the supply unit is transferred to a combustion chamber such as a turbine boiler by high pressure air supplied from one side to another side by a transfer unit such as a blower fan provided at the lower portion of the storage unit.

Here, when the excessive amount of biomass is injected into the storage space, the storage space may be exploded due to various gases generated in large quantities from the biomass at one time. Explosion-proof openings for discharging gas are formed at equal intervals, and the explosion-proof openings are equipped with an opaque aluminum cover.

The cover is separated from the explosion-proof opening to the outside by the explosion pressure when the storage space is exploded in a high pressure state by a variety of gases generated in a large amount of biomass, thereby large amounts in the storage space through the explosion-proof opening Various generated gases can be discharged to the outside.

However, since the cover made of an opaque aluminum material blocks external light, the inside of the storage space becomes dark, that is, the mining efficiency is extremely lowered, and thus the operator can replace and maintain the supply part as necessary. There is a problem that is difficult to do.

The present invention was created in order to solve the above-mentioned problems, and since the cover mounted on the explosion-proof opening is made of a transparent synthetic resin material, the light efficiency of the storage space formed between the outer walls can be greatly improved. Since the storage space can be brighter, the operator can replace and maintain the supply part more easily as necessary, and furthermore, due to the inclined part in which the outer wall is inclined downward to the inside of the outer wall at the lower inner periphery. It is an object of the present invention to provide a structure of a biomass silo in which the lower endurance of the outer wall can be improved not only significantly but also a larger amount of biomass can be stored in the storage space.

In order to achieve the above object, the present invention provides a structure of a biomass silo in which biomass used as a fuel of a boiler is stored, the outer wall having a cylindrical shape vertically formed on an upper portion of a bottom plate provided at a lower portion thereof; A storage space formed between the outer walls and storing biomass; A roof provided at an upper portion of the outer wall, the explosion-proof opening communicating with the storage space at equal intervals, and having a transparent synthetic resin cover mounted on the explosion-proof opening; And a supply unit rotatably provided on the bottom plate of the outer wall to supply the biomass stored in the storage space in a downward direction of the storage space.

Here, the lower inner periphery of the outer wall is preferably formed inclined downwardly toward the inner side of the outer wall toward the lower side from the upper side.

Furthermore, the cover is preferably made of polycarbonate.

In addition, the cover is preferably formed with a plurality of grooves of a predetermined interval in the longitudinal direction of the cover.

In addition, the surface of the roof is formed with a protrusion protruding in the upper direction, the explosion-proof opening is formed in the inner side of the protrusion, the cover is a lower portion of the horizontal plate in contact with the upper portion of the protrusion, the end of the horizontal plate A vertical plate vertically formed in a lower direction, and a fastening plate horizontally formed on the lower portion of the vertical plate to be fastened by a fastening member to the surface of the roof around the protruding portion, the fastening plate of the cover O-rings are preferably provided between the lower part and the surface of the roof.

According to the present invention, since the cover mounted on the explosion-proof opening formed at equal intervals on the surface of the roof is made of a transparent synthetic resin material, external light can be more easily passed through the cover to be mined into a storage space formed between the outer walls. That is, the mining efficiency can be greatly improved, and thus the storage space can be brighter, so that an operator can more easily replace and maintain the supply unit as necessary.

In addition, since the inclined portion is formed downwardly toward the inner side of the outer wall toward the lower inner periphery of the outer wall, not only the durability of the lower portion of the outer wall can be improved more, but also a larger amount of the storage space. There is an effect that the biomass can be stored.

In addition, since the cover is made of a transparent polycarbonate, there is an effect that the light efficiency to the storage space can be further improved.

Furthermore, since a plurality of grooves are formed in the cover, when the cover is separated from the explosion-proof opening to the outside by the explosion pressure of the storage space, the cover is separated from the explosion-proof opening in the state in which the cover is broken into small pieces. In this way, there is an effect that it is possible to prevent secondary accidents more easily, that is, injuries are not generated due to the cover separated from the explosion-proof opening to the outside.

In addition, since the O-ring is provided between the lower surface of the fastening plate of the cover and the upper surface of the roof, it is possible to more easily prevent the possibility that foreign matters such as rainwater enter the storage space through the explosion-proof opening. There is.
