It sets, mainly solves the problems, such as that existing acid seal device is above-mentioned.
Technical solution used by the utility model is：A kind of acid seal device in sulfuric acid production system, including top
Lid and cylinder, the head cover are connected with partition board, and the partition board is inserted into cylinder, and the lower partition is equipped with several mistakes
Filter opening；The cylinder both sides are equipped with acid inlet and acid mouth, the cylinder body bottom inclined floor, the cylinder side edge bottom
Portion is additionally provided with sewage draining exit able to turn on or off, and the sewage draining exit is located at the lower side of inclined floor.
Further, the head cover is that vertical welding is connect with partition board.
Further, the cylinder inboard wall is equipped with card slot, and the card slot is adapted with partition board size.
Further, the card slot is two, is located at the both sides up and down of cylinder inboard wall.
Further, the head cover is additionally provided with the exhaust outlet with valve.
Further, the head cover is connect with cylinder by bolt and nut.
Further, the sewage draining exit is equipped with blank flange control and opens and closes.
Further, the head cover, cylinder, partition board and inclined floor material are corrosion resistant alloy material.
The utility model has the beneficial effects that：Due to taking above-mentioned technical proposal, cleaning maintenance is convenient, corrosion-resistant, uses
Long lifespan；While filtration is also carried, the impurity such as remaining broken ceramic ring, make row to cycle acid tank in the good filter acid of energy
Acid solution more cleans.

Specific implementation mode
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1 combinations Fig. 2, Fig. 3, the acid seal device provided by the utility model in sulfuric acid production system is main
It is used for returning in acid tube line for sulfate system, flue gas to be escaped with acid in tower when purpose prevents pipeline acid discharge, the acid seal device knot
Structure is reasonable, and antiseptic property is good, and practical function is good；Its in the duct by flanged joint, including head cover 1 and cylinder 2 are described
Head cover 1 is connected with partition board 3, and the partition board 3 is inserted into cylinder 2, and 3 lower part of partition board is equipped with several filter hole 31, mistake
31 pore size of filter opening is freely adjustable, and hole count is related with the bore in acid tube road is returned, and the gross area for filtering punching is more than or equal to back
The bore in acid tube road；2 both sides of cylinder are equipped with acid inlet 21 and acid mouth 22, the 2 bottom angled bottom plate 23 of cylinder,
The 2 side bottom of cylinder is additionally provided with sewage draining exit 24 able to turn on or off, and it is lower that the sewage draining exit 24 is located at inclined floor 23
Side.The head cover 1 is that vertical welding is connect with partition board 3.1 inner wall of cylinder be equipped with card slot 11, the card slot 11 with
3 size of partition board is adapted.The card slot 11 is two, is located at the both sides up and down of 1 inner wall of cylinder, and partition board 3 is right when installing head cover 1
Head cover 1 plays guiding function, facilitates installation, and when equipment is run, sulfuric acid has certain impact power, card slot 11 to carry partition board 3 on partition board 3
