Further, the device also comprises a medicament adding pump which is connected with a medicament tank; the inlet of the agent feeding pump is provided with a tee joint, and three interfaces of the tee joint are respectively connected with an acidic cleaning agent pipe, an alkaline cleaning agent pipe and an agent tank; ball valves are respectively arranged on the acidic cleaning agent pipe and the alkaline cleaning agent pipe.
Further, a pH agent is arranged in the agent tank and used for detecting the pH value of the cleaning agent in the agent tank.
Furthermore, the cleaning agent is an acidic cleaning agent, and a corrosion inhibitor is added in the acidic cleaning agent.
Furthermore, the cleaning agent is an alkaline cleaning agent, and a surfactant is added in the alkaline cleaning agent.
Has the advantages that: 1. the medicament feeding pump is controlled by frequency conversion and is matched with a pH agent arranged in the medicament tank to control the concentration of the cleaning medicament in the whole medicament tank;
2. when acid cleaning agent or alkali cleaning agent is needed, the cleaning agent can be realized by opening and closing a ball valve arranged at the inlet end of the dosing pump;
3. a rotational flow distributor is arranged to realize that acid-base cleaning liquid can be uniformly distributed at the upper end of the upper baffle plate of the submerged burner;
4. an aeration head is arranged at the bottom of the submerged burner, and dirt is removed from the interior of the submerged burner by using gas scouring in the process of cleaning the dirt;
5. corrosion inhibitors (such as hexamethylene tetramine and the like) are added into the acid cleaning agent to reduce the corrosion of the acid cleaning agent to the immersed combustion furnace; the surfactant (such as EDTA disodium) is added into the alkali cleaning agent to increase the cleaning effect;
6. this landfill leachate is with submerged combustion ware cleaning system can effectively get rid of the inside dirt of adhering to submerged combustion ware, guarantees the continuous steady operation of submerged combustion ware.
Drawings
FIG. 1 is a schematic structural view of the present invention;
reference numbers in the figures: 1. a submerged burner; 2. a medicament canister; 3. a drug dosing pump; 4. cleaning the circulating pump; 5. a medicament delivery conduit; 6. a baffle plate; 7. a swirl distributor.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The utility model comprises a medicament adding pump 3, a medicament conveying pipeline 5, a cleaning circulating pump 4, a medicament tank 2 and an aeration device in an immersion burner 1. The medicament adding pump 3 adopts frequency conversion control and is matched with a pH agent arranged in the medicament tank 2 to control the concentration of a cleaning medicament in the whole medicament tank. The medicament delivery pipeline 5 is connected with the submerged burner 1, and the outlet position of the medicament delivery pipeline is positioned above the baffle plate 6 at the upper part of the submerged burner 1; the cleaning circulating pump 4 provides a large flow rate of cleaning scale layer, the cleaning liquid in the agent tank 2 is pumped into the submerged burner 1, and the cleaning agent flows down from the baffle plate 7 at the upper part of the submerged burner 1; the bottom of the medicament tank 2 is connected with a cleaning circulating pump 4, and the top of the medicament tank is connected with a liquid outlet of the submerged burner 1; the aeration device in the submerged burner 1 is arranged at the bottom inside the submerged burner.
Three connectors are arranged at the inlet of the medicament feeding pump 3, ball valves are arranged on pipelines, and when acid cleaning agents or alkali cleaning agents are needed, the effect is achieved by opening and closing the ball valves arranged at the inlet end of the medicament feeding pump 3; the position where the medicament delivery pipe 5 is connected with the submerged burner 1 is provided with a cyclone distributor 7, so that acid-base cleaning liquid can be uniformly distributed at the upper end of the upper baffle plate 6 of the submerged burner 1. The flow of the cleaning circulating pump 4 is more than or equal to 2m3And h, adjusting a flow pump of the cleaning circulating pump 4 according to the amount of dirt in the submerged combustor 1, forming a higher flow speed on the surface of the dirt layer, and accelerating the dissolution of the dirt layer. The agent tank 2 plays a role in preparing an acid-base cleaning agent and plays a role of a circulating groove in the process of cleaning a scale layer. 4-6 aeration heads are installed on the aeration device at the bottom of the submerged burner 1, and in the process of cleaning dirt, the dirt is removed from the submerged burner 1 by using gas scouring.
The acid cleaning agent can adopt hydrochloric acid, sulfuric acid, citric acid and the like, and a corrosion inhibitor (such as hexamethylenetetramine and the like) is added into the acid cleaning agent to reduce the corrosion of the acid cleaning agent to the immersed combustion furnace; the alkali cleaning agent can adopt sodium hydroxide and the like, and a surfactant (such as EDTA disodium) is added into the alkali cleaning agent to improve the cleaning effect.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
