Description

Technical Field

[0001] The utility model relates to an air duct system, in particular to an air duct system in front of a sulfur incinerator, and belongs to the technical field of pipeline transformation. Background Art

[0002] The position of the fan duct 3 of the sulfur incinerator 1 in the original furnace of the acid-making system entering the interior of the sulfur incinerator 1 is relatively low. Once the charge is not burned completely, a slight accumulation of material at the bottom of the furnace will hinder the supply of compressed air to the sulfur incinerator 1, affecting the combustion of the charge. The incomplete combustion will cause the furnace temperature to be low, thereby making the accumulation of material more serious. At this time, it is necessary to shut down the machine and organize manual labor to clean up the accumulation of material at the bottom of the furnace, which affects the normal operation of the acid-making system and also increases the labor intensity of the workers. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a sulphur incinerator furnace front air duct system. When there is material accumulation at the bottom of the sulphur incinerator causing the furnace front fan air duct to be blocked or clogged, valves I and II are opened, and compressed air is introduced from branch air ducts I and II at higher positions to ensure that the oxygen concentration content in the sulphur incinerator meets the standard and the accumulated material at the bottom of the furnace is fully burned.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A sulphur incinerator inlet air duct system comprises a sulphur incinerator inlet air duct connected to the sulphur incinerator through a sulphur inlet air duct, the sulphur incinerator inlet air duct is divided into two paths after being led out from the sulphur inlet air duct and connected to the sulphur incinerator through two air inlets respectively, and the two air inlets are located on opposite sides of the sulphur incinerator and at the bottom; branch air outlets are respectively provided above the two air inlets on the sulphur incinerator, and the two branch air outlets are respectively connected to the sulphur incinerator inlet air duct through a branch air duct I and a branch air duct II, and valves I and valve II are respectively provided on the branch air duct I and the branch air duct II.

[0006] A further improvement of the technical solution of the present utility model is that it includes a sulfur dioxide concentration monitor arranged in the chimney at the top of the sulfur incinerator, and the sulfur dioxide concentration monitor is connected to an alarm located outside the furnace wall.

[0007] A further improvement of the technical solution of the present invention is that the air duct of the furnace front fan gradually narrows from the furnace front fan end to the sulfur burning furnace end.

[0008] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0009] The utility model provides branch air ports above the two air inlets on the sulfur incinerator, and the two branch air ports are connected to the air duct of the furnace fan through the branch air duct I and the branch air duct II respectively. When material accumulation occurs at the bottom of the sulfur incinerator, resulting in poor air distribution or blockage of the air duct of the furnace fan, valves I and valve II are opened, and compressed air is supplied into the sulfur incinerator through the branch air duct I and the branch air duct II, thereby ensuring the oxygen content in the sulfur incinerator, allowing the material accumulation at the bottom of the furnace to be fully burned, ensuring the normal operation of the overall furnace temperature of the sulfur incinerator and the acid making system, and saving labor costs.

[0010] A sulfur dioxide concentration monitor is provided in the chimney at the top of the sulfur incinerator of the utility model. The sulfur dioxide concentration monitor is connected to an alarm located on the outside of the furnace wall. When the sulfur dioxide concentration content discharged to the outside by the chimney is higher than the set sulfur dioxide concentration value, the alarm will sound an alarm, so that relevant staff can check and solve the problem in the first time and ensure that the accumulated materials at the bottom of the furnace can be fully burned.

[0011] The utility model discloses a furnace front fan air duct which gradually narrows from one end of the furnace front fan to one end of the sulfur incinerator, so that the compressed air blown by the furnace front fan has a higher pressure and can enter the sulfur incinerator more smoothly without being blocked.

[0015] The present invention is further described in detail below with reference to the embodiments:

[0016] like Figure 1 As shown, a sulfur incinerator front air duct system includes a sulfur incinerator 1, a furnace front fan 2, a furnace front fan air duct 3, a valve I 4, a branch air duct I 5, a valve II 6, a branch air duct II 7, a sulfur dioxide concentration monitor 8, an alarm 9 and a chimney 10.

[0017] like Figure 2As shown, the position of the fan duct 3 of the sulfur incinerator 1 of the original furnace of the acid production system entering the interior of the sulfur incinerator 1 is relatively low. Once the charge is not burned completely, a slight accumulation of material at the bottom of the furnace will hinder the supply of compressed air to the sulfur incinerator 1, affecting the combustion of the charge and causing the furnace temperature to be low, thereby making the accumulation of material more serious. At this time, it is necessary to shut down the machine and organize manual labor to clean up the accumulation of material at the bottom of the furnace, which affects the normal operation of the acid production system and also increases the labor intensity of the workers.

[0018] In the first embodiment of the present invention, branch air ports are respectively opened above the two air inlets on the sulfur incinerator 1, the positions of the branch air ports are slightly higher than the top of the accumulated materials, and the two branch air ports are respectively connected to the air duct 3 of the fan in front of the furnace through the branch air duct I5 and the branch air duct II7. When accumulated materials accumulate at the bottom of the sulfur incinerator 1, resulting in poor air supply or blockage of the air duct 3 of the fan in front of the furnace, valve I4 and valve II6 are opened, and compressed air is supplied to the sulfur incinerator 1 through the branch air duct I5 and the branch air duct II7 to ensure the oxygen content in the sulfur incinerator 1, so that the accumulated materials at the bottom of the furnace can be fully burned, thereby ensuring the normal operation of the overall furnace temperature of the sulfur incinerator 1 and the acid production system, and saving labor costs.

[0019] In the second embodiment of the present invention, a sulfur dioxide concentration monitor 8 is provided inside the sulfur incinerator 1. The sulfur dioxide concentration monitor 8 is connected to an alarm 9 located outside the furnace wall. When the sulfur dioxide concentration discharged to the outside by the chimney 10 is higher than the sulfur dioxide concentration setting value of 80 mg / m 3 When the alarm is on, the alarm 9 will sound an alarm, so that the relevant staff can check and solve the problem in the first time to ensure that the accumulated materials at the bottom of the furnace can be fully burned.

[0020] In the third embodiment of the present invention, the air duct 3 of the furnace front fan gradually narrows from one end of the furnace front fan 2 to one end of the sulfur incinerator 1, so that the compressed air blown out by the furnace front fan 2 has a higher pressure and can enter the sulfur incinerator 1 more smoothly without being easily blocked.
