[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figure 3, in this embodiment, a high-efficiency alkali washing tower that is easy to maintain is proposed, including a tower body 1, a base 2, an exhaust pipe 3 and a fan 6. The tower body 1 and the fan 6 are fixedly connected to the upper end of the base 2, one end of the exhaust pipe 3 is connected to the tower body 1, and the other end of the exhaust pipe 3 is connected to the fan 6; the middle and lower sections of the tower body 1 are alkali washing sections, and the upper section of the tower body 1 is a water washing section. The middle section is a concentrated alkali solution, and the alkali solution in the lower section is a dilute alkali solution flowing down from the middle section, and is circulated by a dilute alkali circulation pump, and new alkali solution is continuously fed into the middle section by an alkali solution supply pump. After the acid and alkali waste gas is drawn out from the air duct, it enters the tower body 1, flows upward to the first filter material layer in the tower body 1, and contacts and reacts with the neutralizing liquid sprayed from the nozzle in the water washing section. The absorbed waste gas continues to flow upward to the second filter material layer, contacts with the neutralizing liquid sprayed from the second-stage nozzle, and a neutralization reaction occurs again, and then passes through the swirl plate and is discharged from the exhaust pipe 3 and the fan 6 for purification.

[0022] A plurality of maintenance windows 4 are provided on the outside of the tower body 1, and a plurality of annular passages 5 are provided on the outside of the tower body 1. Each annular passage 5 is respectively placed below each maintenance window 4, and the annular passage 5 is fixedly connected to the tower body 1; the staff maintains the components in the alkali washing section and the water washing section in the tower body 1 through the maintenance windows 4.

[0023] A ladder structure is provided on the side of the tower body 1 away from the fan 6, and an entrance and exit gap 8 is opened on the side of the annular corridor 5 away from the fan 6. The ladder structure passes through each entrance and exit gap 8. A hanging belt structure is provided on the side of the ladder structure away from the tower body 1 to prevent workers from falling from the ladder structure.

[0024] If the tower body 1 is relatively high, the workers need to climb the ladder structure to reach the top of the tower body 1. The annular corridor 5 supports the workers to step on and operate around the tower body 1. In the process of climbing the ladder, when the workers accidentally fall from the ladder structure, the hanging belt structure can continuously protect the workers and improve the safety of the operation.

[0025] About the ladder structure;

[0026] The ladder structure includes a ladder bracket 9, the lower end of the ladder bracket 9 is fixedly connected to the upper end of the base 2, and the upper end of the ladder bracket 9 is fixedly connected to each circular aisle 5 in turn. A plurality of pedals 10 are arranged in the ladder bracket 9, and the pedals 10 are fixedly connected to the ladder bracket 9. When climbing the ladder structure, you can walk up and down by stepping on the pedals 10. It should be noted that the ladder bracket 9 and the pedals 10 need to ensure good structural strength.

[0027] About the lanyard structure;

[0028] The hanging belt structure includes a safety bracket 12, the lower end of the safety bracket 12 is fixedly connected to the upper end of the base 2, the upper end of the safety bracket 12 is fixedly connected to the upper end of the ladder bracket 9 through a connecting rod 11, a safety belt 14 is sleeved on the outer side of the safety bracket 12, and a plurality of hook components 13 for limiting the safety belt 14 are provided on the side of the safety bracket 12 away from the ladder bracket 9.

[0029] The safety belt 14 is fixed on the back of the operator. When the operator goes up and down the pedal 10, the operator will move along the safety bracket 12 with the safety belt 14. If the operator accidentally steps on empty space, the operator will fall downward quickly, and the safety belt 14 will also fall together. At this time, the hook assembly 13 on the safety bracket 12 can pull out the safety belt 14 to prevent the operator from falling directly to the ground, thereby protecting the operator.

[0030] It is worth further explaining that the hook assembly 13 includes a fixing portion 15 and a hook body 16, the fixing portion 15 is fixedly connected to the safety bracket 12, the hook body 16 is placed on the upper end of the fixing portion 15 and is integrally formed with the fixing portion 15, and the corner between the hook body 16 and the fixing portion 15 is an arc surface. The advantage of this design is that when the operator steps on the pedal 10 to ascend, the safety belt 14 tied to the operator's back can slide along the arc surface at the corner between the fixing portion 15 and the hook body 16, and will not be stuck between the fixing portion 15 and the safety bracket 12.

[0031] In order to improve the safety of the circular aisle 5, in a preferred solution, a guardrail 7 is provided at the upper end of the circular aisle 5, and the guardrail 7 is fixedly connected to the circular aisle 5 and the ladder bracket 9. The circular aisle 5, the guardrail 7 and the ladder bracket 9 are fixed by welding. When the operator steps onto the circular aisle 5 through the ladder structure, the guardrail 7 can protect the operator and prevent the operator from falling from the circular aisle 5.

[0032] In order to improve the use safety of the pedal 10, the outer side of the pedal 10 is wrapped with a rubber sleeve, and the outer wall of the rubber sleeve is a rough surface, so as to increase the friction between the soles of the staff and the pedal 10, reduce the occurrence of slipping when climbing the ladder, and improve the safety of daily maintenance of the alkali washing tower.

[0033] How this application works:

[0034] The lower and middle sections of the tower body 1 are alkali washing sections, and the upper section of the tower body 1 is a water washing section. The middle section is a concentrated alkali solution, and the alkali solution in the lower section is a dilute alkali solution flowing down from the middle section, which is circulated by a dilute alkali circulation pump, and new alkali solution is continuously fed into the middle section by an alkali supply pump. After the acid and alkali waste gas is led out from the air duct, it enters the tower body 1, flows upward to the first filter material layer in the tower body 1, and contacts and reacts with the neutralizing liquid sprayed from the nozzle in the water washing section. The absorbed waste gas continues to flow upward to the second filter material layer, contacts with the neutralizing liquid sprayed from the second-stage nozzle, and reacts with the neutralization reaction again, and then passes through the swirl plate and is discharged from the exhaust pipe 3 and the fan 6 for purification.

[0035] The staff maintains the components in the alkali washing section and the water washing section of the tower body 1 through the maintenance window 4. If the tower body 1 is relatively high, the staff needs to climb the ladder structure to reach the top of the tower body 1, and the circular aisle 5 supports the staff to step on and operate around the tower body 1.

[0036] The safety belt 14 is fixed on the back of the operator. When the operator goes up and down the pedal 10, the operator will move along the safety bracket 12 with the safety belt 14. If the operator accidentally steps on empty space, the operator will fall downward quickly, and the safety belt 14 will also fall together. At this time, the hook assembly 13 on the safety bracket 12 can pull out the safety belt 14 to prevent the operator from falling directly to the ground, thereby protecting the operator.
