The escape pipe of described filter is nested in the aldehyde gas discharge pipe.
Gas outlet opposite end/side is provided with the lifting part on the described filtration skeleton, and the lifting part comprises and is connected in the connecting rod that links to each other between two blocks of side plates filtering on the skeleton and the side plate.
Aldehyde gas discharge pipe opposite side is provided with filter mounting in the described still mouth, and the lifting part is overlapped on the filter mounting.
Described filtration skeleton is circular or square linear tube.
Described filtration skeleton is circular or square ring pipe.
Described aldehyde gas passage is a strip, is distributed on to filter on the skeleton sidewall.
Described screen pack is coated on and filters on the skeleton sidewall, and screen pack is three layers, and the mesh diameter ecto-entad of three layer filtration net reduces gradually.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model is installed filter in the still mouth, and is simple in structure, and impurity is removed rate up to 95%, and power consumption is few, and is durable in use, saves aldehyde gas production cost, and alleviated the live load of the refining workshop section of furfural production greatly, reduced the equipment cleaning frequency.
2, filter is arranged between aldehyde gas discharge pipe and the filter mounting, installs, dismounting is easy, flexible operation; The escape pipe of filter is nested in the aldehyde gas discharge pipe, realizes being tightly connected, and prevents that gas from leaking, and improves furfural gas discharge efficiency.
3, on the filtration skeleton, coat screen pack,, prevent that furfural dregs dirt from entering aldehyde feed channel, good filtration effect in order to filtering furfural dregs dirt; The mesh diameter ecto-entad of three layer filtration net reduces gradually, and furfural gas is filtered layer by layer, improves impurity and removes rate.
4, be provided with the lifting part filtering on the skeleton, be convenient to the carrying of filter, mounting box is deposited.

The specific embodiment
Embodiment 1
Hydrolysis kettle as shown in Figure 1, it comprises the still mouth 7 on kettle 6, kettle 6 tops and the kettle cover 8 on the still mouth 7, is provided with aldehyde gas discharge pipe 10 on still mouth 7 sidewalls, aldehyde gas discharge pipe 10 opposite sides are provided with filter mounting 9 in the still mouth 7, play a supporting role.Be provided with filter 1 between aldehyde gas discharge pipe 10 and filter mounting 9, filter 1 is tightly connected with aldehyde gas discharge pipe 10, makes furfural gas discharge kettle 6 by filter 1 through aldehyde gas discharge pipe 10.
Filter as shown in Figures 2 and 3, it comprises tubular filter skeleton 11, filtering skeleton 11 is circular linear tube, and sealed at both ends, sets out gas port 16 at filtration skeleton 11 1 ends, 16 places outwards are provided with escape pipe 12 in the gas outlet, the internal diameter of the external diameter of escape pipe 12 and aldehyde gas discharge pipe 10 adapts, and escape pipe 12 is nested in the aldehyde gas discharge pipe 10, realizes being tightly connected, prevent that gas from leaking, improve furfural gas discharge efficiency.Aldehyde gas passage 14, the six place's aldehyde gas passages 14 that offer six director's strips on filtration skeleton 11 circumferential wall are distributed on and filter on skeleton 11 circumferential wall, as the filtration channel of furfural gas; Simultaneously, filtering coating three layer filtration net 15 on skeleton 11 circumferential wall,, prevent that furfural dregs dirt from entering the aldehyde feed channel in order to filtering furfural dregs dirt.The mesh diameter ecto-entad of three layer filtration net 15 reduces gradually, and furfural gas is filtered layer by layer, improves impurity and removes rate.Be provided with lifting part 13 in the opposite end of filtering escape pipe 12 on the skeleton 11 or gas outlet 16, lifting part 13 comprises and is connected in the connecting rod 18 that links to each other between two blocks of side plates 17 filtering on the skeleton 11 and the side plate 17.The outside of above-mentioned side plate 17 is wedge shape wide at the top and narrow at the bottom, and is downward more fixing firm more when side plate 17 and filter mounting 9 are joined.For side plate 17 and filter mounting 9 are matched, filter mounting 9 is set to the shape that the wedge shape with side plate 17 adapts.
