Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1 is air storing duct, and 2 be material inlet, and 3 be material outlet, and 4 be material Loading Pump, and 5 go to unload station for material, 6
It is tail gas regulating valve for air inlet adjustment valve, 7,8 be nitrogen-making device, and 9 be differential pressure transmitter, and 10 be spray absorber.
Embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, are further elaborated the utility model.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, air storing duct VOCs master gas devices, including multiple air storing ducts 1, the bottom of air storing duct 1 are equipped with thing
Material entrance 2 and material outlet 3, material inlet 2 are connected by pipeline with material production workshop, are provided with the material outlet 3
Material Loading Pump 4, the outlet of material Loading Pump 4 are gone to unload station 5 and are connected by transfer pipeline and material.
The top of the air storing duct 1 offers nitrogen inlet and offgas outlet, and nitrogen inlet is respectively connected with by pipeline
Air inlet adjustment valve 6, the other end of air inlet adjustment valve 6 and the gas outlet connect afterwards with nitrogen-making device 8 connect, air inlet adjustment valve 6
