Detailed Description
In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
Example 1:
a compound fertilizer tail gas particulate matter washing system is shown in figure 1 and comprises a forward washing air passage 1, a sedimentation tank 2, a demisting air passage 3 and a spray tower 4, wherein the forward washing air passage 1, the demisting air passage 3 and the spray tower 4 are vertically arranged, a smoke through pipe 5 of compound fertilizer tail gas is communicated with an air inlet at the upper end of the forward washing air passage 1, an air outlet at the lower end of the forward washing air passage 1 extends downwards to a position below the liquid level of the sedimentation tank 2, the top of the sedimentation tank 2 is communicated with an air inlet at the lower end of the demisting air passage 3, a demister 6 is horizontally arranged in the demisting air passage 3, gas entering the demisting air passage 3 is discharged from an air outlet of the demisting air passage 3 after passing through the demister 6, the number of the air outlets of the demisting air passage 3 is 2-3 and is uniformly arranged on the side wall of the demisting air passage 3, one demister 6 is respectively arranged at the lower side of each air outlet, the air outlet of the demisting air passage 3 is communicated with the air inlet at the lower end of the spray tower 4, and an exhaust port at the top of the spray tower 4 is communicated with the outside atmosphere. A plurality of spray headers 7 are respectively arranged at the top ends of the forward washing air passage 1, the demisting air passage 3 and the spray tower 4, and are used for respectively washing, spraying and dedusting the gas. Wherein, wash air flue 1 in the same direction as, the spray header 7 on defogging air flue 3 and 4 tops of spray tower respectively through last water branch pipe 8, water pump 9 and 2 inside intercommunications in sedimentation tank, sedimentation tank provides the spray water source for the spray header, simultaneously wash air flue 1 in the same direction as, the water droplet of whereabouts directly falls into sedimentation tank 2 again in defogging air flue 3, avoid extravagant, collector pipe 10 and sedimentation tank 2 intercommunication are passed through to the bottom of spray tower 4, the water of whereabouts converges into sedimentation tank 2 through collector pipe 10 in the spray tower 4.
Compound fertilizer tail gas pumped from a production workshop enters the forward washing air passage 1 from an air inlet at the upper end of the forward washing air passage 1 through the smoke passage 5, the compound fertilizer tail gas continuously moves (namely flows downwards) along the forward washing air passage 1, and meanwhile, a spray head 7 at the upper end of the forward washing air passage 1 sprays downwards; meanwhile, downward water flow continuously washes towards gas, dust-containing particles in the gas can be prevented from entering the spray header 7, the spray header 7 is prevented from being blocked, and 40% of fertilizer particle dust can be removed through direct washing in the direct washing gas passage 1. The compound fertilizer tail gas after primary sequential washing continues to descend and enters the sedimentation tank 2, and because the space in the sedimentation tank 2 is larger than that of the sequential washing air passage 1, part of heavier particle dust is quickly settled in the sedimentation tank 2 due to sudden increase of the space and sudden reduction of air pressure. Then compound fertilizer gas continues to rush out the liquid level and continues upwards to get into defogging air flue 3, decurrent rivers constantly wash towards gas simultaneously, three-layer demister 6 arranges in proper order, and partial compound fertilizer gas is discharged through the gas outlet behind first demister 6, and partial compound fertilizer gas is discharged from the gas outlet behind two demister 6, and remaining compound fertilizer gas is discharged through the gas outlet behind three demister 6, carries out the backwash dust removal to dusty gas by the shower nozzle of defogging air flue 3 upper end, can remove granule dust 50%. The compound fertilizer gas discharged from the gas outlet enters the spray tower 4, the compound fertilizer gas continues to go upwards in the spray tower, meanwhile, downward water flow continuously goes towards the upward gas for third flushing, and about 9% of fine particle dust can be removed after the compound fertilizer gas is back-flushed again in the spray tower 4, so that the complete standard-reaching discharge is realized.
Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent replacement and modification or partial replacement that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
