Description

Pyrolysis of coal cleaner unit guiding device

Technical field

This utility model belongs to dust removal by filtration technical field, especially relates to the coal heat of pyrolysis of coal, biomass pyrolytic generation Solve cleaner unit guiding device.

Background technology

The pyrolysis gas temperature that pyrolysis of coal, biomass pyrolytic produce, at 300 ~ 700 DEG C, carries a small amount of raw material powder in pyrolysis gas Dirt, needed through hot precipitator, pyrolysis gas is carried out dedusting, the pyrolysis gas ability after dedusting before collecting pyrolysis gas Subsequent processes is used effectively.The most conventional has: cyclone centrifugal dust collection, electrostatic precipitation, solid particle dedusting etc., whirlwind Centrifugal dust-removing is disadvantageous in that and cannot filter diameter less than the dust of 10 μm, and efficiency of dust collection is low；Electrostatic precipitation is wanted The resistivity seeking dust itself controls within the specific limits, so its design structure is complicated and cost is high.

Solid particle dedusting there is problems of dust and constantly piles up between solid particle, bonds, and can affect dedusting effect Rate, there is potential safety hazard in the pressure increase in dust arrester: the open a kind of granule dedusting of application number 201210180811.5 filters Device and dust removal and filtration method.The granule dedusting filter of the present invention, including: dust removal filter main body, feed system, air inlet system System and gas outlet and discharging opening；Wherein, described dust removal filter main part is made up of filter housings and inner member；Described Inner member is made up of turriform baffle group, is arranged at inside filter housings；Described feed system is by bed depth adjusting rod, inner core And charging aperture is constituted；Described gas handling system is made up of air inlet and admission line.This invention utilizes solid particle material as mistake Filter medium is in order to cleaning high-temp dusty gas, or removes the impurity component such as dust, heavy tar in pyrolysis gas, its weak point It is: the solid particle material of use needs continual interpolation to ensure dust removing effects, and the dust-removing process making this aspect is complicated, And tar and dust can cause the phenomenon of bonding when being attached on solid particle material, thus cause the phenomenon that discharging opening blocks Occur.

Chen Wujun, Yang Guohua disclose ceramic filter high-temperature dust removal technology progress (University Of Ningbo's journal, the 21st The volume third phase, in JIUYUE, 2008), to ceramic filter element and structure, filter failure safety (CPP) system and ceramic filter Several aspects such as high temperature gas cleaning integrated technique are commented, and summarize the pluses and minuses of filter and following ceramic filter The research direction of device, when the test tube type filter mentioned in literary composition uses: dusty gas enters filter from bottom, wears outside pipe Crossing ceramic wall and realize filtering, the granule trapped falls in ash bucket.The common structure of this device is designed as: the first side Case: the import of pyrolysis gas is positioned close to cleaner unit inlet plenum top, i.e. near the dividing plate of filtering bodies, its shortcoming is: pyrolysis gas Charge air flow the most laterally flings the filter core vertically played, and filter element is easily fractureed by the cross force of air-flow, and air-flow is removing simultaneously In dirt device, distributed pole is uneven, and dust is more uneven in each site distribution of filtering bodies, filter element heading on and the back side at air-flow, is glued Attached Dust Capacity is mutually more poor, thus affects the filter capacity of filter element；Another kind of scheme: the import of pyrolysis gas is arranged on filtering bodies Filter element lower end with the import of lower portion, i.e. pyrolysis gas less than the lower end of filter element, so cause pyrolysis gas when filtering, air-flow one Directly rising past, and the dust filtered out is being blocked by ascending air to the process fallen, dust can be kicked up again Filter, dust is difficult to fall from core region, and filter element is easily quickly blocked.
