Description

Technical Field

[0001] This utility model relates to the field of denitrification equipment technology, specifically to an SNCR polymer intelligent denitrification device. Background Technology

[0002] SNCR, or Selective Non-Catalytic Reduction, refers to the process of reducing nitrogen oxides in flue gas into harmless nitrogen and water by injecting a reducing agent within a suitable "temperature window" for denitrification without the aid of a catalyst. SNCR polymer intelligent denitrification equipment is based on the SNCR technology principle, utilizing a polymer reducing agent to react with nitrogen oxides (NOx) within a specific temperature range. x The reduction reaction occurs, converting it into nitrogen and water. The polymeric reducing agent has the characteristics of high reactivity and wide decomposition temperature range, and can achieve efficient denitrification under a wider range of working conditions. In existing SNCR polymer intelligent denitrification equipment, the mixing method of reducing agent and flue gas is relatively simple. Usually, the reducing agent is directly sprayed into the equipment to react with the flue gas. However, because the flue gas flows rapidly in the equipment, the contact time between the reducing agent and the flue gas is short, making it difficult for the sprayed reducing agent to fully mix with the flue gas. This may result in incomplete mixing of the reducing agent and flue gas, affecting the denitrification effect of the denitrification equipment. Utility Model Content

In this embodiment, the flue gas velocity is reduced by the cooperation between the intake pipe 6 and the multiple deceleration nets 7 set inside the intake pipe 6, so that the flue gas can slowly enter the mixing box 3, thereby prolonging the contact time between the flue gas and the reducing agent and enhancing the mixing effect of the flue gas and the reducing agent. In this embodiment, the coordination between the transmission rod 4, the disturbance plate 5, and the linkage mechanism achieves disturbance of the flue gas and the reducing agent, increases the contact area between the flue gas and the reducing agent, further extends the contact time between the flue gas and the reducing agent, ensures that the reducing agent can be fully mixed with the flue gas, and thus ensures the denitrification effect of the denitrification equipment.

[0015] like Figure 1As shown, a protective box is installed on one side of the main body 1 of the denitrification equipment. A fan is installed inside the protective box. The fan's input end is connected to one side of the main body 1 of the denitrification equipment via a suction pipe, and the fan's output end is connected to an exhaust pipe. The denitrified flue gas is discharged to the appropriate location through the fan and exhaust pipe. A slag discharge pipe is connected to the lower side of the main body 1 of the denitrification equipment, and waste slag is discharged from the main body 1 of the denitrification equipment through the slag discharge pipe. Figure 2 As shown, separation plates are installed on both sides of the bottom wall of the main body 1 of the denitrification equipment. The separation plates can separate flue gas and waste residue. like Figure 2 As shown, the mixing box 3 is located on the top of the inner wall of the main body 1 of the denitrification equipment. The lower side of the mixing box 3 is connected to the upper side of the filter mechanism 2 through a connecting pipe. Two transmission rods 4 rotate on one side of the inner wall of the mixing box 3. The disturbance plate 5 is sleeved on the transmission rod 4 and can deflect around the transmission rod 4. Two spray nozzles 8 are arranged symmetrically on both sides of the inner top wall of the mixing box 3. The top of the spray nozzles 8 is connected to an external pipe, which is connected to an external liquid supply device. The linkage mechanism is located on one of the two sides of the main body 1 of the denitrification equipment. The two transmission rods 4 can rotate synchronously under the drive of the linkage mechanism. Figure 3 As shown, the linkage mechanism includes a reciprocating deflection assembly and a transmission assembly. The reciprocating deflection assembly includes a mounting frame 101, a rotating shaft 102, and a deflection plate 103. The mounting frame 101 is installed on one of the two sides of the denitrification equipment body 1. The rotating shaft 102 is rotatably installed between the mounting frame 101 and the denitrification equipment body 1. The mounting frame 101 is provided with a driving component for driving the rotating shaft 102 to rotate. The driving component is a reciprocating motor. The deflection plate 103 is sleeved on the rotating shaft 102 and can... Driven by the rotating shaft 102, it can reciprocate around the rotating shaft 102 as the center. The transmission assembly includes a transmission plate 201, a T-shaped transmission seat 202 and a connecting plate 203. The transmission plate 201 is installed on the outside of the transmission rod 4 and can deflect around the transmission rod 4 as the center. Two T-shaped transmission seats 202 are installed on the inner side of the deflection plate 103 and the transmission plate 201, respectively. The two connecting plates 203 are respectively sleeved on two of the four T-shaped transmission seats 202. like Figure 1 and Figure 3As shown, the intake pipe 6 is connected to the upper side of the mixing box 3. The intake pipe 6 is equipped with a deceleration mesh 7. The intake pipe 6 is multi-segmented and bendable. There are multiple deceleration meshes 7, which are distributed in an orderly manner along the bend path of the intake pipe 6. The multi-segmented intake pipe 6 can prolong the intake time of the flue gas. The multiple deceleration meshes 7 can effectively slow down the flow speed of the flue gas. The lower side of the intake pipe 6 is connected to a receiving cylinder 9. The receiving cylinder 9 is located inside the intake pipe 6, directly below the deceleration mesh 7 at the first bend. Impurities intercepted by the deceleration mesh 7 will fall into the interior of the receiving cylinder 9. A sealing plug is inserted into the lower side of the receiving cylinder 9.

[0016] Working principle: Before applying the denitrification equipment, connect all pipes within the equipment to the corresponding external equipment, and then debug the equipment to ensure it can operate normally. When applying the denitrification equipment, flue gas enters the inlet pipe 6 and flows within it. When the flue gas passes through the deceleration mesh 7, it is disturbed and dispersed. The flow of the flue gas decreases under the action of multiple deceleration meshes 7, and the reduced-speed flue gas enters the mixing chamber 3. Simultaneously, the external liquid supply equipment delivers the reducing agent through an external pipe to two spray nozzles 8. The spray nozzles 8 spray the reducing agent into the mixing chamber 3, where it comes into contact with and mixes with the flue gas. During the mixing process, the reciprocating motor is started, driving the rotating shaft 10. 2. The rotating shaft 102 drives the deflection plate 103 to reciprocate. The deflection plate 103 drives the transmission plate 201 to reciprocate through the T-shaped transmission seat 202 and the connecting plate 203. The transmission plate 201 drives the transmission rod 4 to reciprocate. The transmission rod 4 drives the disturbance plate 5 to reciprocate. The reciprocating disturbance plate 5 disturbs the flue gas and reducing agent, prolonging the contact time between the flue gas and the reducing agent and increasing the contact area between the flue gas and the reducing agent, thus realizing the mixed denitrification of the flue gas and the reducing agent. The denitrified flue gas enters the filter mechanism 2 through the connecting pipe. The filter mechanism 2 separates the flue gas and the waste residue. The separated flue gas is discharged to the corresponding position through the fan and the exhaust pipe. The waste residue is discharged out of the main body 1 of the denitrification equipment through the slag discharge pipe.
