Description
Technical Field
The utility model relates to the technical field of environmental protection equipment, in particular to a desulfurization device of a boiler.
Background
The existing boiler desulfurization tower is shown in fig. 2, and comprises a flue gas inlet 1, a cyclone plate 12, a spray header 5, a demister device 14, a back flushing device 15 and a flue gas outlet 6, wherein after entering from the flue gas inlet, flue gas enters from the flue gas inlet, passes through the cyclone plate, is mixed with reaction liquid of a plurality of spray headers to desulfurize the flue gas, and is discharged from the flue gas outlet after being cleaned by the back flushing device; the device has high energy consumption and low efficiency, and the maintenance of the spray header and the demister device is very troublesome.
Disclosure of Invention
In order to solve the technical problems, the utility model aims to provide a high-efficiency spray desulfurization device which comprises an inner container and an outer container, wherein the inner container penetrates through an upper end cover of the outer container; the upper part of the space between the inner container and the outer container is closed; the upper end of the outer liner is provided with a smoke inlet; a spiral channel is arranged between the inner container and the outer container, and the upper end of the spiral channel is connected with the flue gas inlet; the upper end of the spiral channel is also provided with a spray header; the lower end of the spiral channel is communicated with the lower end of the inner container, and a smoke outlet is arranged above the inner container; the spiral channel is provided with a step.
The spray heads are multiple groups and are uniformly arranged along the circumferential direction of the liner.
The spray header is fixed on a bracket, and the bracket is erected between the inner liner and the outer liner.
The utility model has the advantages that: the flue gas passes through a plurality of rotations in the tower, changes the desulfurization mode, improves desulfurization efficiency, and the adjustment is convenient.

Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic diagram of a prior art structure.
Detailed Description
The utility model will be described in detail with reference to the accompanying drawings, as shown in the drawings, the utility model comprises an inner container 4 and an outer container 3, wherein the inner container passes through an upper end cover 31 of the outer container; the upper part of the space between the inner container and the outer container is closed;
the upper end of the outer container is provided with a smoke inlet 1; a spiral channel 2 is arranged between the inner container and the outer container, and the upper end of the spiral channel 2 is connected with a flue gas inlet 1; the upper end of the spiral channel 2 is also provided with a spray header 5; the lower end of the spiral channel 2 is communicated with the lower end of the inner container 4, and a smoke outlet 6 is arranged above the inner container; the spiral channel is provided with a step 21; the step 21 is arranged to increase the contact area between the flue gas and the reaction liquid sprayed by the spray header as much as possible and increase the reaction time; the reaction liquid sprayed out of the spray header flows down along the steps and collides with the flue gas just above the steps, so that the reaction time and the reaction area are increased.
Preferably, the spray heads are multiple groups and are uniformly arranged along the circumferential direction of the liner.
The spray header is fixed on a bracket 51 which is erected between the inner container and the outer container. The bracket is not only used for fixing the spray header, but also increases the connecting structure between the inner container and the outer container, and ensures the integral strength of the equipment.
