Detailed Description

The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and give detailed implementation manners and specific working procedures, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1-3, the hydrothermal type filtering apparatus suitable for multistage treatment of oily and sticky tail gas comprises a stainless steel double-layer outer sealed barrel 1 fixed on the ground through a bottom support leg 101, a detachable top cover 102 mounted on the top through a bolt, and a leak-proof gasket arranged between the top cover 102 and a stainless steel flange plate on the top of the double-layer outer sealed barrel 1 for preventing gas leakage in the barrel.

An inner flow guide cylinder 2 is arranged in the inner cavity of the double-layer outer sealing barrel 1, the inner diameter of the inner flow guide cylinder 2 is smaller than that of the double-layer outer sealing barrel 1, and the inner flow guide cylinder is formed by rolling and welding stainless steel plates. The top welding of interior water conservancy diversion drum 2 has the stainless steel card 201 that is used for installing filter core 3, and the sealed welding of card 201 outer fringe is on the inner wall of double-deck external seal bucket 1, makes the bottom of interior water conservancy diversion drum 2 be located double-deck external seal bucket 1 bottom plate top, even both clearance settings.

The side wall of the double-layer outer sealing barrel 1 is provided with an air inlet butt joint pipe 301, an air outlet butt joint pipe 302, a nitrogen purging pipe 303 and a bottom condensation discharging pipe 304 (the condensation discharging pipe 304 is provided with a condensation discharging valve 305), wherein the air inlet butt joint pipe 301, the nitrogen purging pipe 303 and the condensation discharging pipe 304 penetrate through the inside and the outside of the barrel, the air outlet butt joint pipe 302 is positioned above the flower plate 201, and the air inlet butt joint pipe 301, the nitrogen purging pipe 303 and the condensation discharging pipe 304 are positioned below the flower plate 201. The air inlet butt joint pipe 301 and the air outlet butt joint pipe 302 are tangentially arranged along the side wall of the double-layer outer sealing barrel 1, and the air inlet butt joint pipe 301 is arranged close to the flower plate 201.

When the double-layer outer sealing barrel works, oil-containing tail gas enters an inner cavity of the double-layer outer sealing barrel 1 through the air inlet butt joint pipe 301, then rotates along an interlayer between the double-layer outer sealing barrel 1 and the inner diversion cylinder 2 to move downwards, enters each filter element 3 after reaching an opening at the bottom of the inner diversion cylinder 2 and continuously moves upwards, and finally is discharged out of the double-layer outer sealing barrel 1 through the air outlet butt joint pipe 302 through the top cover 102 of the double-layer outer sealing barrel 1. Oily tail gas obtains filtering when filter core 3, and the impurity of filtering is attached to on filter core 3, and nitrogen gas sweeps pipe 303 blows into high-pressure nitrogen gas in filtering gap to the bucket, and impurity falls in double-deck external seal bucket 1 bottom at gravity and the dual function of sweeping, opens row and congeals valve 305, makes impurity discharge outside the bucket.

Further, in order to accelerate the falling of the impurities, a hot water inlet pipe 306 and a hot water outlet pipe 307 are further installed on the side wall of the double-layer outer sealing barrel 1, the hot water inlet pipe 306 and the hot water outlet pipe 307 are both communicated with the interlayer inner cavity of the double-layer outer sealing barrel 1, and the hot water inlet pipe 306 is located above the hot water outlet pipe 307. The hot water inlet pipe 306 and the hot water outlet pipe 307 can be opened when the tail gas is filtered and the impurities are removed, so that the temperature in the barrel is increased, and the flowability of the impurities is increased.

In order to prevent the situation that the filter element 3 is blocked due to the fact that the impurity liquid level in the double-layer outer sealing barrel 1 is too high due to the fact that the condensate discharging valve 305 is not opened in time, a standby air inlet hole 308 can be formed in the inner flow guide cylinder 2, oil-containing smoke can enter the filter element 3 from the standby air inlet hole 308 under special working conditions, and the safety of device operation is guaranteed.

In addition, for convenience of disassembly and assembly and replacement, handles are mounted on the detachable top cover 101 and each filter element 3.

It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
