Embodiment 1

[0009] Example 1 Composition and function of a boiler ash removal pneumatic conveying system:

[0010] A rotary feeder positive pressure dilute-phase boiler ash removal pneumatic conveying system includes Roots blower 1, gas-solid mixing acceleration chamber 2, electric rotary feeder 3, pumping chamber 4, manual flapper valve 5, and material hopper 6. Composition of material and compressed air conveying pipeline 7, pneumatic switching valve 8, silo 9, pulse blowback bag type silo dust collector 10, silo activation hopper 11, silo pneumatic discharge valve 12, and electrical control system 13 It is characterized in that the combination of the air flow of the Roots blower 1 and the rotary feeder 2 realizes the positive pressure dilute phase pneumatic conveying, which can convey short distances and continuously, the conveying system is simple, and it can be conveyed from one point to multiple points. Gray pneumatic conveying system. Roots blower 1 is used to provide air source...

Embodiment 2

[0011] Example 2 Working process of a boiler ash removal pneumatic conveying system:

[0012] After the powder material is added from the material hopper 6, the electric rotary feeder 3 of the rotary feeder is fully mixed by the gas-solid mixing acceleration chamber 2 and is pressed from the lower outlet to the material and compressed air delivery pipeline 7. According to the process and The production needs are distributed into the silo 10 by the pneumatic switching valve 8 and discharged through the outlet of the silo pneumatic discharge valve 12 .

Abstract

The invention relates to a boiler dust removal pneumatic transmission system, particularly to a boiler dust removal pneumatic transmission system applicable to the positive-pressure dilute phase of a rotary feeder. The boiler dust removal pneumatic transmission system comprises a Roots blower 1, a gas-solid mixing accelerating chamber 2, an electric rotary feeder 3, an suction chamber 4, a pneumatic gate valve 5, a material hopper 6, a material and compressed air transmission pipe 7, a pneumatic reversing valve 8, a storage bin 9, a pulse jet pocket type bin dust cleaner 10, a storage bin activating hopper 11, a storage bin pneumatic discharging valve 12 and an electric control system 13. The boiler dust removal pneumatic transmission system has the advantages of, through combination of the rotary feeder and the Roots blower, achieving uniform and continuous transmission and being simple and easy to maintain.

Description

technical field [0001] The invention relates to a pneumatic conveying system for boiler ash removal, which is especially suitable for long-distance transportation of boiler ash with small bulk density and high bulk ratio, and can be transported from one point to multiple points. field of transport technology. Background technique [0002] Traditional pneumatic conveying of boiler ash mostly adopts large-flow Roots blower dilute-phase low-speed conveying, which requires a large flow of Roots blower, large motor power, large energy consumption, and high operating costs. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies of the prior art, and provide a combination of Roots blower and rotary feeder to realize positive pressure dilute phase conveying, a matching motor with low power, and continuous and uniform conveying Rotary feeder positive pressure dilute phase boiler ash pneumatic conveying system. The object of the pres...
