Feeding machine device for sucking furfural residues into boiler under negative pressure

Abstract

The invention discloses a feeding machine device for sucking furfural residues into a boiler under negative pressure. The feeding machine device comprises a hydrolyzed pan, a gas holder and a residueshed, wherein a residue discharge pipeline is fixedly connected to one side of the hydrolyzed pan, the top of the gas holder is fixedly connected with the residue discharge pipeline, a negative-pressure conveying pipeline is arranged in the residue shed, a suction nozzle is fixedly connected to the bottom of the negative-pressure conveying pipeline, a high-pressure fan is fixedly connected to oneend of the negative-pressure conveying pipeline, a material conveying pipe is fixedly connected to one side of the high-pressure fan, and a material and gas separator is fixedly connected to the bottom of the material conveying pipe. According to the feeding machine device, the gas holder, the residue discharge pipeline, the negative-pressure conveying pipeline, the suction nozzle, an air pipe, the high-pressure fan, the material conveying pipe, a suction fan, an air inlet pipe, an air outlet pipe, an elbow, an exhaust gas buffer bottle and a buffer solution are arranged, so that the problem of large potential safety hazards when employees enter the residue shed to view the production status or load and convey residues due to low visibility in the residue shed because the residue shed is sealed when the furfural residues with high water vapor are discharged to the residue shed is solved.

Description

technical field [0001] The invention relates to the technical field of furfural slag feeding equipment, in particular to a device for feeding furfural slag into a boiler under negative pressure. Background technique [0002] Furfural slag is a waste produced in the process of biomass hydrolysis. It has high salt content and is acidic. Its large accumulation will pollute the atmosphere, soil and rivers. As a kind of biomass waste, furfural residue contains a large amount of cellulose, hemicellulose and lignin, and has good reuse value. Therefore, rational resource utilization of furfural slag, eliminating its environmental pollution, increasing the economic added value of furfural slag, realizing the goal of zero pollutant discharge in the production process of furfural enterprises, and achieving the purpose of clean production and recycling are furfural The utilization of slag resources is an urgent problem to be solved. The direction of resource utilization of furfural sl...

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a furfural slag negative pressure absorption into the boiler feeder device, which solves the problem that the furfural slag has a large water vapor and is discharged into the slag shed. Due to the sealing of the slag shed, the visibility in the slag shed is low. , there is a big potential safety hazard when employees enter to check the production situation or load and transport slag
