Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to an organic waste gas spraying intelligent joint control system. Background Art

[0002] In the actual production process, industries such as chemical industry, electronics, metallurgy, electroplating, textile (chemical fiber), and machinery manufacturing often generate a large amount of organic waste gas. These organic waste gases need to be filtered and purified by spray purification devices during the emission process to prevent the organic waste gas from being directly discharged to the outside and polluting the surrounding air.

[0003] Publication number "CN213590100U" provides an organic waste gas adsorption spray treatment equipment. The waste gas enters the treatment box from the air inlet, passes through the first-level adsorption mechanism, the first-level spray mechanism, the second-level adsorption mechanism, the second-level spray mechanism, and the defogger plate in turn, and finally discharges from the treatment box from the air outlet. The first-level nozzle and the second-level nozzle continuously spray the adsorption liquid to the first-level mesh plate and the second-level mesh plate respectively. When the adsorption liquid flows to the first-level mesh plate and the second-level mesh plate, a water curtain will be formed. When the waste gas passes through the first-level mesh plate and the second-level mesh plate, the adsorption liquid will absorb the organic components in the waste gas, achieving the absorption effect.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] First of all, the first-level adsorption mechanism, first-level spray mechanism, second-level adsorption mechanism, second-level spray mechanism and defog plate in the organic waste gas adsorption spray treatment equipment are all located inside the treatment box and are non-detachable structures, which makes it extremely inconvenient to replace and clean them after a period of use. Secondly, the first-level spray mechanism and the second-level spray mechanism in the organic waste gas adsorption spray treatment equipment do not have automatic start and stop capabilities. When the organic waste gas no longer enters the treatment box and the staff does not shut it down in time, the first-level spray mechanism and the second-level spray mechanism will continue to work, thereby increasing the power consumption of the equipment, and its practicality needs to be improved.

The water outlet end of the circulating water pump 511 is connected to the water pipe 58, and the front end of the water pipe 58 is fixedly connected to the connecting pipe 512. When working, the circulating water pump 511 will transport the organic waste gas inside the supporting bottom box 4 to the primary diversion shell 54 and the secondary diversion shell through the water pipe 58 and the connecting pipe 512 respectively.

The left end face of the primary flow diversion shell 54 and the right end face of the secondary flow diversion shell 55 are both provided with a plurality of atomizing nozzles 59. The primary flow diversion shell 54 will divert the organic waste gas to the plurality of atomizing nozzles 59 with an absorption solution, so that the plurality of atomizing nozzles 59 can spray toward the primary mesh plate 24. The secondary flow diversion shell 55 will divert the organic waste gas to the plurality of atomizing nozzles 59 with an absorption solution, so that the plurality of atomizing nozzles 59 can spray toward the secondary mesh plate 23. The left and right sides of the interior of the treatment box 1 are symmetrically fixedly connected with water baffles 53, which will The atomizing nozzle 59 blocks and guides the organic waste gas absorption solution through the primary mesh plate 24 and the secondary mesh plate 23 to prevent the organic waste gas absorption solution from being sprayed onto the activated carbon filter 25 and the flat-plate demister 21. A filter residue mesh plate 52 is inserted into the upper side of the interior of the supporting bottom box 4.

[0037] Working principle: When the programmable logic controller 56 senses through the infrared gas sensor 51 that the amount of organic waste gas entering the treatment box 1 is higher than the preset value, the programmable logic controller 56 will start the circulating water pump 511 and the external blower through the intelligent relay 57. At this time, the circulating water pump 511 will work to support the organic waste gas inside the bottom box 4 and transport the absorption solution to the primary diversion shell 54 and the secondary diversion shell through the water guide pipe 58 and the connecting pipe 512 respectively, and the primary diversion shell 54 will divert the organic waste gas to the absorption solution up to Atomizing nozzles 59 are provided so that the multiple atomizing nozzles 59 can spray the primary mesh plate 24 and the secondary mesh plate 23 respectively, and the organic waste gas absorption solution sprayed on the surface of the primary mesh plate 24 and the secondary mesh plate 23 will naturally slide down to the inside of the support bottom box 4 for recycling. In this process, the filter residue mesh plate 52 will block the insoluble matter in the organic waste gas absorption solution entering the inside of the support bottom box 4 to prevent the circulating water pump 511 from being easily blocked; at the same time, the working external blower will generate negative pressure inside the treatment box 1 so as to treat The organic waste gas in the air intake pipe 3 is quickly inhaled by the box 1. During this process, the activated carbon filter 25 pre-absorbs and purifies the organic waste gas. Then, the organic waste gas is purified twice by the primary screen 24 sprayed with the organic waste gas absorption solution, and then purified three times by the secondary screen 23 sprayed with the organic waste gas absorption solution. Then, the organic waste gas is separated into gas and liquid by the flat-plate demister 21 and enters the air outlet pipe 6. At the same time, the water baffle 53 is used to filter the organic waste gas through the primary screen 24 and the secondary screen. The organic waste gas from the plate 23 is blocked and guided down with an absorption solution to prevent the organic waste gas from being sprayed onto the activated carbon filter 25 and the flat-plate demister 21 with an absorption solution. In the later use process, when the programmable logic controller 56 senses through the infrared gas sensor 51 that the amount of organic waste gas entering the treatment box 1 is lower than the preset value, the programmable logic controller 56 will shut down the circulating water pump 511 and the external blower respectively through the intelligent relay 57, thereby reducing the power consumption of the circulating water pump 511 and the external blower, thereby making the system more energy-efficient.
