Detailed Description

The utility model will be described in detail below with reference to the drawings and the detailed description.

As shown in fig. 2, a spray device, the structure includes: a spray tower 1, a pollution discharge control device and a filter press 2;

the spray tower 1 comprises a tower body, wherein an air outlet pipe 3 is arranged at the top of the tower body, a water outlet arranged at the lower part of the side wall is connected with a spray water pump 4, the spray water pump 4 is connected with a water inlet end of a spray water pipe 5, a water outlet end of the spray water pipe 5 is connected with a water inlet arranged at the upper part of the side wall of the tower body, the lower part of the tower body is conical, a sewage outlet is arranged at the bottom of the tower body, and the sewage outlet is connected with a sewage drain valve 6; the lower part of the side wall of the tower body is provided with a water supplementing port, the water supplementing port is connected with the water outlet end of the water supplementing pipe 7, the water supplementing valve 8 is arranged on the water supplementing pipe 7, the water supplementing valve 8 is an electromagnetic valve, the water inlet end of the water supplementing pipe 7 is connected with a water recycling device, the lower part of the tower body is provided with a liquid level meter 9, and the liquid level meter 9 is connected with the water supplementing valve 8; an air inlet arranged on the side wall of the lower part of the tower body is connected with an air inlet pipe 10;

the sewage disposal control device comprises a turbidity meter 11, an alarm 12 and a PLC controller, wherein the turbidity meter 11 is arranged at the inner bottom of the spray tower 1, the signal output end of the turbidity meter 11 is connected with the input end of the PLC controller, and the control output end of the PLC controller is connected with the control input ends of the alarm, the sewage disposal valve and the water supplementing valve;

the water inlet end of the filter press 2 is connected with the blow-down valve 6 through a water pump 13, and the water outlet end of the filter press 2 is connected with a water inlet arranged on the side wall of the lower part of the tower body of the spray tower through a pipeline 14.

Fig. 1 is a schematic diagram of a structure of a conventional spray device, gas containing materials enters through an air inlet pipe 10, water sprayed out through a spray pipe 5 sprays purified gas, the water containing the materials falls into the bottom of a spray tower 1, and the purified gas is discharged through an air outlet pipe 3. The water containing materials can spray through the spray water pump 4 again through the spray water pipe 5, and as the materials are gradually accumulated, the spray water contains more and more materials, and the spray effect can be poorer and worse, so that the sewage containing materials needs to be discharged in time so as not to block the spray tower. The water is discharged, and meanwhile, the water is also required to be timely supplemented through an electromagnetic water supplementing valve 8 interlocked with a liquid level meter 9, so that the phenomenon of empty pumping or water-free spraying of a pump is avoided. Therefore, the spray tower needs to be changed once per shift, the water consumption is high, and the risk of blocking the spray tower due to material accumulation is high.
