Description

Technical Field

[0001] The utility model relates to a desulfurization cyclone anti-blocking device. Background Art

[0002] Hydrocyclones are widely used in various industries and are important equipment for separating media. In the limestone-gypsum wet flue gas desulfurization process of power plants, hydrocyclones are indispensable and are mainly used in the following three aspects: limestone slurry preparation, gypsum primary dehydration, and wastewater treatment.

[0003] Because limestone contains debris such as wood, rubber, hard stones, and cable sheathing, and the slurry contains debris such as wood, gypsum crystals, and rubber, cyclones often clog. Minor blockages affect cyclone efficiency, while severe blockages prevent the equipment from operating normally and require shutdown for cleaning. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a desulfurization cyclone anti-blocking device.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A desulfurization cyclone anti-blocking device comprises a box body, wherein two filter cavities are separated by a partition in the box body, a filter screen is fixed obliquely in each of the filter cavities, an inlet pipe is fixed at one end of one of the filter cavities of the box body, and an outlet pipe is fixed at the other end;

[0007] An inlet branch pipe is fixed at one end of another filter inner cavity of the box, and an outlet branch pipe is fixed at the other end;

[0008] The inlet branch pipe is connected to the inlet pipe, and the outlet branch pipe is connected to the outlet pipe;

[0009] The bottom of each filtering inner cavity is provided with a cone bucket, the bottom of the cone bucket is provided with a waste outlet pipe, and the waste outlet pipe is connected to the waste collecting pipe.

[0010] In the desulfurization cyclone anti-blocking device, the collecting pipe is a cylindrical pipe arranged obliquely.

[0011] The desulfurization cyclone anti-blocking device has a top cover plate fixed on the top of the box body.

[0012] In the desulfurization cyclone anti-blocking device, the inlet pipe, the inlet branch pipe, the outlet pipe, the outlet branch pipe, the miscellaneous pipe and the miscellaneous pipe are all equipped with isolation valves. Beneficial effects

[0013] 1. The utility model can effectively filter the slurry that is about to enter the cyclone, and can block the debris through the filter plate to prevent it from clogging the cyclone.

[0014] 2. The utility model is provided with two filter cavities, one for main use and the other for backup. When filtering, after the filter screen plate of one filter cavity runs for a period of time, the filter screen plate of the other filter cavity is switched to filter by switching the isolation valve, and then the filter cavity that stops filtering is effectively cleaned without affecting the desulfurization operation.

[0021] like Figure 1-5 As shown, a desulfurization cyclone anti-blocking device comprises a housing 11, wherein two filter cavities are separated by a partition 12 in the housing, and a filter screen 8 is fixed obliquely in each of the filter cavities. An inlet pipe 3 is fixed at one end of one of the filter cavities of the housing, and an outlet pipe 6 is fixed at the other end.

[0022] The inlet pipe is fixed on the side of the filter plate that is tilted toward the side;

[0023] An inlet branch pipe 2 is fixed at one end of the other filter inner cavity of the box, and an outlet branch pipe 5 is fixed at the other end;

[0024] The inlet pipe and the inlet branch pipe are fixed on the same side of the box, and the outlet pipe and the outlet branch pipe are fixed on the same side of the box;

[0025] The inlet branch pipe is connected to the inlet pipe, and the outlet branch pipe is connected to the outlet pipe;

[0026] The bottom of each of the filter cavities is provided with a cone bucket 7 , and the bottom of the cone bucket is provided with a waste outlet pipe 10 , which is connected to a waste collection pipe 9 .

[0027] In the desulfurization cyclone anti-blocking device, the collecting pipe is a cylindrical pipe arranged obliquely.

[0028] The desulfurization cyclone anti-blocking device has a top cover plate 4 fixed on the top of the box body.

[0029] In the desulfurization cyclone anti-blocking device, the inlet pipe, inlet branch pipe, outlet pipe, outlet branch pipe, miscellaneous pipe and miscellaneous pipe are all equipped with a barrier valve 1, which is a butterfly valve.

[0030] Working principle: When in use, first close all the barrier valves, connect the inlet pipe of the device with the main pipe for supplying slurry to the cyclone, so that the slurry supplied to the cyclone through the slurry main pipe will enter the box for filtration, then open the barrier valves of the inlet pipe and outlet pipe, the slurry enters through the inlet pipe, filters the impurities through the filter screen, and the filtered slurry is discharged through the outlet pipe, while the blocked impurities will fall into the cone bucket. After this filter cavity has been running for a period of time, it needs to be replaced with another filter cavity, open the barrier valve of the inlet branch pipe and the barrier valve of the outlet branch pipe, close the barrier valves of the inlet pipe and outlet pipe, and then the slurry will enter through the inlet pipe and then enter another filter cavity through the inlet branch pipe, be filtered through the filter screen in this filter cavity, and then pass through the outlet branch pipe and finally be discharged through the outlet pipe;

[0031] The blocked debris will fall into the cone bucket. At this time, the filter cavity that has been running for a period of time should be cleaned, the bolts on the top cover plate on the filter cavity should be removed, the top cover plate should be removed, and then the blocking valves on the outlet pipe and the collecting pipe should be opened. The filter screen should be rinsed with water to clean the filter screen. The cleaned debris will enter the collecting pipe through the outlet pipe and then be discharged through the collecting pipe.
