Problems solved by technology

Due to its light weight, low density, large angle of repose, and poor flow, biomass is prone to channeling and bridging during the feeding process, and it is not easy to achieve continuous and stable feeding; moreover, the feeder system is easy to During the feeding process, due to the heat generated by the screw, the biomass feeder, which is easy to stick and bridge, cannot operate normally, and the blocking phenomenon occurs frequently

Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, a gas delivery biomass feeder of the present invention includes an air supply pipe 10, an air inlet pipe, a feed pipe 9 and a storage pipe 4 for containing biomass materials; the air supply pipe 10 and the air inlet pipe Fixed connection and gas conduction, the inlet pipe is sleeved on the feed pipe 9, and the feed port of the feed pipe 9 is arranged in the tube hole at the second end of the storage pipe 4, and the storage A sealing plug 2 that can move axially along the storage tube 4 is provided in the tube hole at the first end of the tube 4, and the first end of the sealing plug 2 is fixedly connected with the push rod 1; the first end of the storage tube 4 The two ends are sealed and connected with the outer wall of the air intake pipe through the first variable diameter joint 3; the first end of the air intake pipe is arranged in the storage pipe 4, and the second end of the air intake pipe passes through the second variab...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the feed port of the feed pipe 9 is flush with the gas outlet of the air intake pipe, and the feed port of the feed pipe 9 is flush with the gas outlet of the air intake pipe. The air outlet is above the biomass material and is 2 to 3 mm away from the horizontal surface of the biomass material, the inner diameter of the first air inlet pipe 5 and the second air inlet pipe 6 is 4 mm, and the outer diameter of the feed pipe 9 is 3 mm, that is The difference between the inner diameter of the inlet pipe and the outer diameter of the feed pipe 9 is less than 3 mm. In this case, the use of the present invention to transport biomass materials to the gasifier can also achieve the effect of stable feeding. Minute feed 0.500 grams calculation, the error is only ± 0.015 grams.

Embodiment 3

[0032] Embodiment 3 (comparative example)

[0033] The difference between this embodiment and Embodiment 1 is that the inner diameter of the first air inlet pipe 5 and the second air inlet pipe 6 is 8 mm, and the outer diameter of the feed pipe 9 is 4 mm. At this time, the air inlet pipe The difference between the inner diameter of the feed pipe 9 and the outer diameter of the feed pipe 9 is greater than 3 mm. Through the air supply pipe 10 to ventilate into the air inlet pipe, no matter how much the gas flow rate is and how much the distance between the inlet of the feed pipe 9 and the gas outlet of the air inlet pipe and the horizontal plane of the biomass material is, it cannot be realized. Feeding: the air flow flows into the material storage pipe through the air inlet pipe and blows on the surface of the material, and then forms a reverse air flow, which drives the material to flow to the feed inlet of the feed pipe 9, but due to the air inlet pipe and the feed material ...

Abstract

The invention discloses a gas conveying biomass feeder, which includes an air supply pipe, an air inlet pipe, a feeding pipe, a feeding pipe and a storage pipe for containing biomass materials; The inlet pipe is set on the feed pipe, the feed port of the feed pipe is set in the tube hole at the second end of the storage tube, and the first end tube hole of the storage tube is provided with a sealing plug that can move along the axial direction of the storage tube , the first end of the sealing plug is fixedly connected with the propulsion rod; the second end of the storage pipe is sealed and connected with the outer wall of the intake pipe through the first reducing joint. The biomass is transported in the feeder by using gas. By controlling the intake rate, the material can be conveyed at a uniform speed, and the continuous non-blocking feeding can be realized, the adhesion between the material and the inner wall of the feeder can be reduced, and the material blockage can be avoided; At the same time, the equipment is easy to use, and the basic investment cost and maintenance cost are low; the present invention can not only transport biomass, but also transport coal particles and similar powders.

Description

technical field [0001] The invention relates to the field of biomass energy transportation, in particular to a biomass feeder for gas transportation. Background technique [0002] Biomass is the fourth largest energy source in the world. The thermochemical conversion process of biomass involves the stable and uniform feeding process of biomass. At present, the feeding technology of biomass generally adopts screw feeder system. Due to its light weight, low density, large angle of repose, and poor flow, biomass is prone to channeling and bridging during the feeding process, and it is not easy to achieve continuous and stable feeding; moreover, the feeder system is easy to During the feeding process, due to the heat generated by the screw, the biomass feeder, which is easy to bond and bridge, cannot operate normally, and the blocking phenomenon occurs frequently. Contents of the invention [0003] In view of this, the object of the present invention is to provide a gas conve...
