Compared with prior art, the present invention has following useful technique effect:
Dust-laden carbonization gas dust arrester of the present invention, filtrate enters in dedusting cavity from top to down, is then enter in cavity from deduster cavity bottom, moves from bottom to top by dedusting carbonization gas.So, the filtrate of cold conditions be there is heat exchange by dedusting carbonization gas is always continual, hot carbonization gas temperature from bottom to top reduces gradually, and the temperature of cold conditions filtrate from top to bottom raises gradually, defines good thermograde, is conducive to the carrying out of dedusting.Simultaneously, gas collecting apparatus is connected with the gas liquor joint sealing of dedusting containment portion by pipeline, gas liquor joint sealing is that the carbonization gas completing dedusting is carried out dedusting again, and has the effect of gas collection and water seal concurrently simultaneously, reduces the processing pressure of subsequent purification system with this.This filtrate of the present invention from top to bottom, carbonization gas reverse-flow filtration from bottom to top, the stratum granulosum voidage impact that the movement of stratum granulosum is hung down on airflow direction on filtering gas is less, in addition the dust of stratum granulosum deposition reduces gradually on filtering gas airflow direction, and the always clean particle that filtering gas ran into before leaving stratum granulosum.Therefore, effectively prevent the back-mixing of dust and carrying secretly, its dust removing effects than cross-current type and downflow type superior, have a good application prospect.
Further, the present invention is also provided with distribution device in cavity, and distribution device is covered with the cross section of whole cavity, can ensure by carbonization gas by even gas distribution.
Further, be also provided with sub-material umbrella between distribution device of the present invention and filtrate outlet, at the uniform velocity and to greatest extent evenly discharging of filtrate can be ensured.
