Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tail gas treatment equipment, more particularly to a phosphorus compound fertilizer drying tail gas dust collection chamber. BACKGROUND

[0002] In the production process of ammonium phosphate, diammonium phosphate and compound fertilizer in chemical fertilizer enterprises, hot air is generated by burning natural gas, which enters the phosphorus compound fertilizer product dryer to dry the just produced product and take away the evaporated water, forming so-called tail gas, which is discharged to the rear section for tail gas treatment. However, the tail gas contains a large amount of powdery chemical fertilizer and cannot be directly discharged. According to the national environmental protection requirements, PM2.5 and other particles in the discharged tail gas must meet the standard to be discharged, so the subsequent treatment is also quite complex. The rear section dust removal includes dust removal in the dust collection chamber, bag dust removal and electrostatic dust removal processes.

[0003] Most of the commonly used tail gas dust collection chambers need manual replacement of the filter device, and when manual replacement is performed, the equipment often needs to be stopped to ensure the safety of the operators.

[0014] Compared with the prior art, the application has the following advantages:

[0015] 1. In this invention, by setting up a dust collection chamber and a magnet, the connection between the magnet and the gear can be controlled by magnetic force. The connecting rod and the rotating rod are movably connected, making it easier for operators to replace the connecting rod and ensuring that the rotating rod can drive the connecting rod to rotate normally. At the same time, the device can operate normally. By setting up a fixed rod, when the connecting rod rotates and comes into contact with the exhaust gas for dust removal, the adhesion of solid particles to the connecting rod can be reduced by continuously beating the fixed rod, thereby increasing the service life of the connecting rod. At the same time, by setting up a dust collector, the dust collector can collect the falling solid particles. It can also use the cooling water in the cooling chamber to absorb heat and heat the solid particles in the dust collector, preventing the phenomenon of solid particles adhering to the inner wall when not cleaned for a long time, thus increasing the energy utilization rate.

[0016] 2. In this invention, by setting up a cooling chamber and by setting the deflection of each group of blades to be inconsistent, some of the exhaust gas can continuously float up and down under the action of the blades, thereby increasing the floating time of the exhaust gas. At the same time, when the exhaust gas comes into contact with the cooling water, the temperature of the exhaust gas will decrease, causing the exhaust gas to float downwards, so that it can flow into the drying chamber through the connecting pipe. This increases the movement path of the exhaust gas in the device, thereby increasing the treatment time of the exhaust gas and improving the treatment effect of the exhaust gas.

[0017] 3. In this invention, by setting up a drying chamber and slidingly connecting the turntable and the exhaust port, the dried exhaust gas can be filtered once by the turntable before being discharged. The turntable is driven to rotate by the connecting rod, which can effectively avoid the phenomenon of poor filtration effect caused by overuse of the same filter plate. At the same time, due to the large environment of the conical plate, the molecules of the exhaust gas will be more dispersed after entering the conical plate, so that the exhaust gas that has not been fully heated can stay at the conical plate for further heating, thereby reducing the amount of solid particles carried by the dried exhaust gas and improving the dust collection effect.

[0046] The working principle of the present application is as follows: when the staff starts the device, the tail gas enters the inside of the dust falling chamber 1 from the air inlet 7, and the starting of the motor 5 drives the connecting rod one 205 to rotate, and the motor 5 drives the connecting rod one 205 to rotate, which in turn drives the gear two 201 to rotate synchronously, the rotation of the gear two 201 drives the gear one 102 to rotate synchronously through the belt one 111, and the magnet below the gear one 102 is attracted to the magnet one 103, so that the rotation of the gear one 102 drives the magnet one 103 to rotate synchronously, and in turn drives the filter block 113 on the connecting rod 107 to rotate synchronously, which stirs the tail gas and fully contacts with the tail gas, and the filter block 113 rotates synchronously and continuously contacts with the fixed rod 108, which can effectively reduce the adhesion of solid particles in the tail gas to the filter block 113, and the tail gas entering the shell one 101 through the air inlet 7 moves upward due to the effect of heat, and after being filtered by the filter block 113, it is cooled to a certain extent, so that part of the tail gas flows up and down in the filter block 113, and the tail gas filtered by the filter block 113 enters the cooling chamber 2 through the communication port 209, and when the filter block 113 needs to be replaced, the motor one 116 is started, which controls the rotating disc 104 to rotate, and in turn disconnects the magnet one 103 and the gear one 102, and when the motor one 116 rotates 180 degrees and stops rotating, the new magnet one 103 is automatically attracted to the magnet on the gear one 102 under the action of magnetic force, and in turn drives the new filter block 113 to filter, and the staff can replace and clean the connecting rod 107 by rotating the limiting block 114, and the filter block 113 can adsorb solid particles in the tail gas after contacting with the tail gas, and after being hit by the fixed rod 108, the solid particles can fall to the dust collector 118 through the filter plate 109, when the staff needs to recycle the solid particles in the dust collector 118, the control switch 119 is started, which controls the rotating block 125 to rotate, the rotating block 125 rotates to drive the scraper 127 to rotate, and in turn the scraper 127 can scrape the partition one 124, so that the solid particles can flow out of the opening on the fixed block 126 to the dust discharge pipe 120 for discharge, and the cooling water in the cooling chamber 2 absorbing the heat of the tail gas enters the space between the partition one 124 and the protective shell 123 from the water inlet pipe 122 and is discharged from the water outlet pipe 121, and the solid particles in the partition one 124 can be heated when flowing, so that the solid particles on the partition one 124 can be in a dry state, reducing the adhesion of the solid particles, and the rotation of the connecting rod one 205 drives the blade 206 to rotate synchronously, so that the tail gas entering the shell two 203 through the communication port 209 can flow fully, and the water inlet 4 pours the cooling water into the water storage tank 204, which is sprayed out from the water outlet 210.The exhaust gas of the shell 203 can be fully contacted with the cooling water when flowing, thereby reducing the solid particles in the exhaust gas, and the deflection between each group of blades 206 is inconsistent, so that part of the exhaust gas can constantly float up and down under the action of the blades 206, increasing the floating time of the exhaust gas. When the exhaust gas contacts the cooling water, the temperature of the exhaust gas will be reduced, thereby making the exhaust gas float downward, so as to flow into the drying chamber 3 through the communication pipe 8, and the cooling water that absorbs the solid particles and heat in the exhaust gas will flow into the filter screen 208, and then flow into the dust collector 118 through the drain port 207. At the same time, the exhaust gas after cooling will move downward, and then flow into the spiral pipe 311 through the communication pipe 8. The heater 310 will heat the heating block 309 when the exhaust gas flows in the spiral pipe 311, so that the heating block 309 can dry the exhaust gas in the spiral pipe 311 by transmission. After drying, the exhaust gas will move upward, and then flow out of the spiral pipe 311, and then enter the exhaust port 6 from the conical plate 308. Since the environment of the conical plate 308 is larger, the molecules of the exhaust gas will be dispersed after entering the conical plate 308, thereby enabling the exhaust gas that has not been fully heated to stay at the conical plate 308 for further heating, and the dried exhaust gas will enter the exhaust port 6. After the exhaust gas enters the exhaust port 6, the rotation of the connecting rod 205 will drive the gear three 202 to rotate synchronously, so that the gear three 202 can drive the gear four 301 to rotate through the belt two 302, thereby enabling the rotating disc 305 to rotate around the connecting rod one 304, so that the filter plates on the two layers of rotating discs 305 can alternately contact the exhaust port 6, thereby enabling the dried exhaust gas to be filtered again by the rotating disc 305 before being discharged.
