Description

Technical Field

[0001] The invention relates to the technical field of coal chemical industry and raw fuel storage and transportation of coal-fired boilers, and in particular to a biomass storage and transportation system. Background Art

[0002] Conventional coal-fired boilers and coal chemical projects are only equipped with raw fuel coal storage and transportation systems. When the device has a need to blend biomass, in order to reduce project investment, it is generally used in the coal yard using existing facilities such as loaders and grabs to simply blend the purchased biomass particles with coal. This process has a low degree of automation and blending efficiency, uneven blending, low ratio accuracy, and poor operating stability of the raw fuel consumption device.

[0003] The existing biomass storage and transportation system is designed with a belt conveyor system based on the traditional coal transportation system. The unloading storage system needs to set up a special underground receiving station for vehicles. The transportation, transfer and batching links all need to set up conveyors, trestles, transfer stations, buffer warehouses and other facilities. The initial investment of the project is large, the construction period is long, and the economic benefits are poor, which is not conducive to the promotion and utilization of biomass energy in power and coal chemical enterprises. In addition, the particle size of biomass particles is generally around 8mm, and the bulk density is 0.6-0.75t / m 3 There is a big difference between the biomass in powder form and the biomass in powder form. When the positive pressure pipeline pneumatic conveying method is adopted, it is easy to accumulate in the pipeline, thereby blocking the conveying pipeline and causing poor conveying. At the same time, the particles of the positive pressure pipeline pneumatic conveying are severely worn, the material breakage rate is high, and dust pollution is easy to occur in the transportation link.

[0059] The negative pressure conveying device 40 is connected to the biomass storage bin 30 and the raw fuel blending device 50 respectively. The biomass storage bin 30 is provided with a discharge port. The negative pressure conveying device 40 is used to receive the biomass particles and biomass dust output from the biomass storage bin 30, and convey the biomass particles and biomass dust to the raw fuel blending device 50.

The second gas-solid separator 44 also transports the gas after the secondary gas-solid separation to the second dust collector 45, and the second dust collector 45 performs a secondary dust removal on the gas after the secondary gas-solid separation to obtain the biomass particles and biomass dust after the secondary dust removal. The biomass dust and the gas after the secondary dust removal are transported to the fifth air lock feeder 48, the fourth air lock feeder 47 outputs the biomass particles and biomass dust after the secondary gas-solid separation to the raw fuel blending device 50, the fifth air lock feeder 48 outputs the biomass dust after the secondary dust removal to the raw fuel blending device 50, the second dust collector 45 also inputs the gas after the secondary dust removal to the second vacuum pump 46, and the second vacuum pump 46 discharges the gas after the secondary dust removal into the atmosphere to effectively avoid dust pollution.

[0060] The raw fuel blending device 50 is used to receive the biomass particles conveyed by the negative pressure conveying device 40, and mix and convey the biomass material with the preset coal-quality raw fuel according to the preset ratio. The raw fuel blending device 50 includes a coal feeder 51, a mixing belt conveyor 52, a first-level high-precision electronic belt scale 53, and a second-level high-precision electronic belt scale 54.

[0061] It should be understood that in order to avoid the situation where the biomass particles and the preset coal-based raw fuel cannot be mixed due to a failure of the raw fuel blending device 50, the present embodiment proposes a dual-path method for raw fuel blending. The specific negative pressure conveying device 40 also includes a first electric tee 491 and a second electric tee 492. The first electric tee 491 is connected to the fourth air lock feeder 47, and is used to switch the biomass particles output by the fourth air lock feeder 47 to the first biomass material and the second biomass material output to the mixing belt conveyor 52, wherein the first biomass material and the second biomass material include biomass particles and biomass dust after secondary gas-solid separation; the second electric tee 492 is connected to the fifth air lock feeder 48, and is used to switch the biomass particles output by the fifth air lock feeder 48 to the third biomass material and the fourth biomass material to the mixing belt conveyor 52, wherein the third biomass material and the fourth biomass material include biomass dust after secondary dust removal.

[0062] It should be understood that the present embodiment also provides an integrated combined structure of the dust removal gas-solid separator 60, which can replace the gas-solid separator and the dust collector. The use of the dust removal gas-solid separator 60 can eliminate a set of ash unloaders and their transmission mechanisms; eliminate some pneumatic conveying equipment such as connecting air ducts and ash discharge pipes; make the structure compact, lighten the weight, and reduce the cost; and reduce air leakage, which can reduce the air leakage by 3%-4%, which is beneficial to reducing energy consumption.

[0063] It can be understood that in the above-mentioned biomass storage and transportation system, an air supply regulating valve and an air filter can be set at the end of the receiving hopper 10 body to facilitate pipeline aggregate transportation, and the air flow rate can also be controlled by adjusting the opening of the air supply valve to meet the vacuum degree of the transportation pipeline and the needs of conveying materials; a silo top dust collector 70 can also be set on the top of the biomass storage silo 30 to maintain a negative pressure environment in the biomass storage silo 30, which can effectively prevent the dust generated in the feeding and unloading links from overflowing; the first vacuum pump 25 is set on the silo top or the surrounding ground of the biomass storage silo 30; the first dust collector 24 can be a bag dust collector to filter biomass dust in the gas, and then back-blown by pulse air , the biomass dust is blown into the powder collecting cone bucket to further fall into the second air lock feeder 27; one or more cleaning pipelines 80 with suction nozzles and hoses can also be set on the first conveying pipeline 22 and the second conveying pipeline 43, which are used to clean the materials and dust on the ground or equipment platform in the unloading area, improve the material cleaning efficiency, effectively avoid dust pollution, and have good environmental protection performance; and the first conveying pipeline 22 and the second conveying pipeline 43 can both use large-radius wear-resistant elbows with a radius greater than or equal to 5 times the outer diameter of the pipeline at the turning point, which can not only reduce the conveying resistance and avoid material accumulation and blockage at the turning point, but also effectively reduce the wear of the elbow, which is conducive to the long-term and stable operation of the conveying pipeline.

[0064] This embodiment sets up a discharge storage device 20, a negative pressure conveying device 40 and a raw fuel blending device 50, uses the discharge storage device 20 to receive biomass particles, processes the biomass particles, obtains biomass materials, and stores the biomass materials, and then uses the negative pressure conveying device 40 to convey the biomass materials to the raw fuel blending device 50, and the raw fuel blending device 50 then mixes and conveys the biomass materials and the preset coal-based raw fuel according to a preset ratio. That is, the equipment of this embodiment is compactly arranged, the conveying pipeline is flexibly arranged, and the blockage of the conveying pipeline can be effectively avoided, the breakage rate can be reduced, and the investment and operation are economically reasonable; at the same time, it has the characteristics of simple and reliable unloading, storage, and conveying processes, energy saving and environmental protection, high conveying efficiency, accurate weighing and feeding, and high precision in blending raw fuels, which conforms to the design principles of advanced technology, safety and reliability, investment saving, and good engineering adaptability.
