DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1-6 The utility model provides a technical solution: a convenient and detachable spray drying tail gas treatment device, comprising an air inlet 1, an air inlet adjustment member 2 with adjustable air intake volume is installed on the air inlet 1, the air inlet 1 is suitable for most exhaust pipe sizes, and the air inlet adjustment member 2 is installed at the upper end of the air inlet 1. The air inlet adjustment member 2 can be a butterfly valve, which can adjust the size of the air intake volume as needed. At the lower end of the air inlet 1, a liquid storage tank 1 4, a liquid storage tank 2 5, a liquid storage tank 3 6 and a liquid storage tank 4 7 are alternately connected in sequence through a connecting component 3, wherein the liquid storage tank 1 4, the liquid storage tank 2 5, the liquid storage tank 3 6 and the liquid storage tank 4 7 are filled with chemical reagents for treating tail gas. Among them, the chemical reagents inside the liquid storage tank 1 4, the liquid storage tank 2 5, the liquid storage tank 3 6 and the liquid storage tank 4 7 are not fixed and can be selected as needed. The liquid inlet pipe 8 is provided on the outside of the liquid storage tank 1 4, the liquid storage tank 2 5, the liquid storage tank 3 6 and the liquid storage tank 4 7, and the chemical reagents can be replaced according to conditions. Liquid storage tank 1 4, liquid storage tank 2 5, liquid storage tank 3 6 and liquid storage tank 4 7 are provided with gas-liquid separation diaphragms 9 at the upper and lower side ports;

[0025] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , wherein the connection assembly 3 includes a connection welding pipe 31 and a flexible sleeve 32, the flexible sleeve 32 is a PVC corrugated hose with a hollow interior, the connection welding pipe 31 and the air inlet 1 are both clamped on the corresponding liquid storage tank 1 4, liquid storage tank 2 5, liquid storage tank 3 6 and liquid storage tank 4 7. The flexible sleeve 32 is arranged inside the connection welding pipe 31, and a bellows 36 is arranged on the outside of the flexible sleeve 32, and the bellows 36 is connected to the inside of the flexible sleeve 32. After the inside of the flexible sleeve 32 is inflated, the folded corrugations can be stretched and contracted, thereby improving the stability of the connection;

[0026] Furthermore, the connecting weld pipe 31 and the corresponding liquid storage tanks 1 4, 2, 5, 3, 6 and 4, 7 are connected via bearings, and the flexible sleeve 32 is disposed above the bearings. The connecting weld pipe 31 and the corresponding liquid storage tanks 1 4, 2, 5, 3, 6 and 4, 7 are connected via bearings, which can facilitate the connection operation of the connecting weld pipe 31 with other components.

[0027] Furthermore, a fixing sleeve 33 is fixedly installed on the outside of the connecting welded pipe 31, the fixing sleeve 33 and the connecting welded pipe 31 are fixedly welded, and the connecting welded pipe 31 and the fixing sleeve 33 are internally connected. An adjusting screw 34 is threadedly connected to the outer end of the fixing sleeve 33, a pressing plate 35 is fixedly installed on the adjusting screw 34, the flexible sleeve 32 is arranged inside the fixing sleeve 33, and the bellows 36 and the pressing plate 35 are glued. After the adjusting screw 34 is rotated clockwise, the adjusting screw 34 can be gradually inserted into the inside of the fixing sleeve 33, and then the bellows 36 can be compressed by the pressing plate 35, so that the gas inside the bellows 36 enters the inside of the flexible sleeve 32, so that the inside of the flexible sleeve 32 can be inflated; in the same way, after the adjusting screw 34 is rotated in the opposite direction, the bellows 36 is separated from the pressing effect of the pressing plate 35, and it gradually returns to its initial state, and part of the gas inside the flexible sleeve 32 can be sucked into the bellows 36. At this time, the axial position of the connection between the connecting welded pipe 31 and other components is loose, which is easier to disassemble.

[0028] It is worth mentioning that a snap-in groove is provided in the shape of a ring above the connecting weld pipe 31, and a snap-in block is provided in the shape of a ring on the component (the corresponding part of the liquid storage tank) connected to the connecting weld pipe 31, and the snap-in block is snapped into the snap-in groove. In this way, the connecting weld pipe 31 can be quickly snap-connected with the corresponding component.

[0029] Working principle: In the initial state of this convenient and detachable spray drying exhaust gas treatment device, after unscrewing the adjusting screw 34, the pressing plate 35 is separated from the pressing of the bellows 36, and the bellows 36 is reset. At this time, part of the gas inside the flexible sleeve 32 enters the bellows 36, and the inhibitory effect of the flexible sleeve 32 on the connecting parts is reduced, which is easy to install and disassemble; during installation and disassembly, by rotating the adjusting screw 34 in the opposite direction, the adjusting screw 34 drives the pressing plate 35 to press the bellows 36, so that the gas inside the bellows 36 enters the flexible sleeve 32, and the inhibitory effect of the flexible sleeve 32 on the connecting parts is increased, which can improve the stability during use.
