[0001] The utility model relates to the technical field of tail gas treatment in gold smelting industry, in particular to a plunger pump combination device capable of linear drug delivery. Background Art

[0002] During the denitration process of the original tail gas, the equipment uses a 3W-40 / 60 three-cylinder plunger pump to spray the denitrification agent into the quenching and tempering tower to achieve the denitration effect. The gold smelting plant needs to denitrate the acid-making tail gas at the tail gas station in the acid-making section. During the denitration process of the original tail gas, the equipment uses a 3W-40 / 60 three-cylinder plunger pump to spray the denitrification agent into the quenching and tempering tower to achieve the denitration effect.

[0030] When in use, the plunger pump body 3 works by feeding medicine through the liquid inlet pipe 7, and conveying the liquid medicine to the liquid collecting bag 4 through the conveying pipe 8. Then, the liquid medicine reaches the cavity joint 16 through the liquid outlet hose 9 and is sprayed through the nozzle 2. After adding the liquid collecting bag 4, the pressure is adjusted to be constant, and the original gap feeding mode of the plunger body 3 (that is, the agent is sprayed intermittently in the exhaust gas, discontinuously) is changed to a linear feeding mode.
