Preferably, pre-filtering frame is including pre-filtering framework, fixed network and non-woven fabrics, and the fixed network is installed on pre-filtering framework, and the non-woven fabrics laminating can carry out prefilter to the air on the fixed network.

Preferably, the upper fixed frame and the middle fixed frame have the same structure and respectively comprise an outer frame, and the outer frame is internally provided with a net strip arranged in a shape like a Chinese character 'mi' to enhance the supporting strength of the filter element.

Preferably, the ash containing honeycomb filter element is formed by curling filter paper with concave-convex surfaces at intervals and then adhering the filter paper with hot melt adhesive.

Preferably, the flame-retardant honeycomb filter element is formed by crimping flame-retardant filter paper with concave-convex surfaces arranged at intervals and adhering the flame-retardant filter paper with hot melt adhesive.

The utility model provides a pair of honeycomb filter core's beneficial effect lies in: this honeycomb filter core simple structure, reasonable in design, filter area is big, holds grey ability reinforce, and the filter effect is good to possess fire-retardant function. In actual work, gas flows upwards from the bottom, and is firstly prefiltered through a prefilter frame to remove large impurities in the gas, and then enters a flame-retardant honeycomb filter element for filtration, the flame-retardant honeycomb filter element can play the dual roles of reducing the gas temperature and filtering, even sparks mixed in the air can be extinguished through the flame-retardant honeycomb filter element to prevent the ash-containing honeycomb filter element from being damaged, the gas filtered by the flame-retardant honeycomb filter element finally enters the ash-containing honeycomb filter element for filtration, because the partition wall channel of the ash-containing honeycomb filter element is very thin, the number of pipelines is more, the filtration area is greatly increased, and the harmful gas is more thoroughly eliminated than that of a common air filter, and the ash-containing honeycomb filter element has a plurality of honeycombs which are fixed with each other, can dispersedly bear more pressure without deformation or movement, thereby ensuring that the ash-containing honeycomb filter element is more durable, and in addition, the ash, the maintenance period of the automobile can be obviously prolonged.
