Description

Technical Field

[0001] The utility model relates to the technical field of washing tower drainage, in particular to an anti-blocking washing tower device. Background Art

[0002] A washing tower is a new type of gas purification and treatment equipment. It is improved on the basis of a floating packing layer gas purifier and is widely used in the pretreatment of industrial waste gas purification, dust removal, etc.

[0003] At present, a drain pipe is installed on the existing washing tower to drain the sewage after washing the flue gas. When the washing tower is working, the internal sewage will be discharged through the drain pipe. Since there is a lot of sludge in the sewage, the drain pipe will be blocked. Some solutions have also been disclosed in the prior art. For example, Chinese Patent: CN104906895A, discloses a turbulent flow washing tower. By adopting a combined settling tank of inclined plates and inclined tubes, and according to the dust content and physical properties of the circulating acid, the appropriate lengths and inclination angles of the inclined plates and inclined tubes are selected through on-site production tests, and the drain pipe is set to an inclined state to prevent sludge blockage; however, due to the large viscosity of the sludge in the sewage, during the drainage process, the sludge will adhere to the pipe wall, and it is very easy to cause the drain pipe to be blocked for a long time, resulting in poor water discharge and reducing the working efficiency of the washing tower.

[0004] Therefore, the utility model provides an anti-blocking washing tower device. Summary of the Utility Model

[0005] The purpose of the utility model is to propose an anti-blocking washing tower device, which solves the problem that the drain pipe of the existing washing tower is easy to be blocked during sewage discharge, resulting in poor water discharge, realizes that after the drain pipe is blocked, the sewage in the washing tower can be continuously discharged, ensures the sewage discharge efficiency, and greatly improves the dust removal efficiency of the washing tower.

[0008] A second drain pipe, communicating with the bottom of the first drain pipe;

[0009] It further includes:

[0010] A bypass pipe for discharging the sewage in the washing tower after the first drain pipe is blocked. The bypass pipe includes:

[0011] A horizontal section, one end of which communicates with the bent pipe;

[0012] The vertical section is connected to the other end of the horizontal section at a 90° angle, and the other end is communicated with the second drain pipe;

[0013] When the first drain pipe is blocked, the water level inside the first drain pipe rises, and the sewage will flow into the second drain pipe through the bypass pipe and be discharged.

[0014] Preferably, a thermometer is connected to the horizontal section of the bypass pipe, which is used to judge whether the first drain pipe is blocked by the temperature change.

[0024] The following further describes the usage method of the present utility model in conjunction with the drawings and specific embodiments.

[0025] As Figure 1 and Figure 2 shown, an anti-blocking scrubbing tower device includes: a scrubbing tower 1 for wet dust removal, including:

[0026] A first drain pipe 2, which is connected to the scrubbing tower 1 through an elbow pipe 3; the sewage in the scrubbing tower 1 is discharged through the first drain pipe 2.

[0027] A second drain pipe 4, which communicates with the bottom of the first drain pipe 2;

[0028] It further includes:

[0029] A bypass pipe 5, which is used to discharge the sewage in the scrubbing tower 1 after the first drain pipe 2 is blocked. The bypass pipe 5 includes:

[0030] A horizontal section 51, one end of which communicates with the elbow pipe 3; the design of the horizontal section 51 is such that when the sewage passes through, the residence time can be increased, so that the internal temperature rises. The temperature is detected by a thermometer 6, and it is judged whether the first drain pipe 2 is blocked.

[0031] A vertical section 52, one end of which is connected to the other end of the horizontal section 51 at a 90° angle, and the other end communicates with the second drain pipe 4;

[0032] After the first drain pipe 2 is blocked, the water level inside the first drain pipe 2 rises, and the sewage will flow into the second drain pipe 4 through the bypass pipe 5 and be discharged.

[0033] A thermometer 6 is connected to the horizontal section 51 of the bypass pipe 5, which is used to judge whether the first drain pipe 2 is blocked by the temperature change.

[0034] At the elbow pipe 3 at 135 m of the scrubbing tower 1, a new bypass pipe 5 is added to bypass the outlet position of the first drain pipe 2 and directly connect it to the second drain pipe 4 at 26 m. During operation, if the first drain pipe 2 is not blocked, the sewage will be directly discharged from the first drain pipe 2 and will not flow into the bypass pipe 5; when the first drain pipe 2 is blocked and there is no time to drain the water, the sewage will be discharged from the bypass pipe 5, avoiding water overflow. Since the temperature of the sewage is relatively high during the production process, when the sewage is discharged from the bypass pipe 5, the temperature of the bypass pipe 5 will rise to about 60 °C. The inspection personnel can observe the thermometer 6 on the pipeline or touch the bypass pipe 5 by hand to find that the main drain pipe is blocked, and immediately carry out cleaning to eliminate the problem.

[0035] The pipe diameter at the elbow pipe 3 is larger than the pipe diameter of the vertical section 52 of the first drain pipe 2. This is because there is still a lot of sludge in the sewage, and the viscosity is relatively large. The larger pipe diameter is to ensure that after the first drain pipe 2 is blocked, the sewage can be discharged from the bypass pipe 5.

[0036] A communicating pipe 7 is connected to the elbow pipe 3. The communicating pipe 7 is obliquely connected to the scrubbing tower 1 at a certain angle, and the connection position of the communicating pipe 7 and the elbow pipe 3 is lower than the connection position of the communicating pipe 7 and the scrubbing tower 1. The connection position of the communicating pipe 7 and the elbow pipe 3 is lower than the connection position of the bypass pipe 5 and the elbow pipe 3.

[0037] The second drain pipe 4 is installed on the scrubbing tower 1 through a bracket 8. The bracket 8 is used to connect and support the second drain pipe 4.

[0038] Working process: When the scrubbing tower 1 is working, sewage will flow from the scrubbing tower 1 into the communicating pipe 7, flow through the communicating pipe 7 into the first drain pipe 2, and flow from the first drain pipe 2 into the interior of the second drain pipe 4, and be discharged through the second drain pipe 4; because the sludge in the sewage has high viscosity, when the communicating pipe 7 is blocked, the water level in the scrubbing tower 1 will rise, flow out from the elbow pipe 3, enter the interior of the first drain pipe 2, and be discharged through the first drain pipe 2. When the first drain pipe 2 is blocked by the sludge in the sewage, the water level inside the first drain pipe 2 will rise, and the sewage will flow from the elbow pipe 3 at the upper end of the first drain pipe 2 into the interior of the bypass pipe 5, and the sewage will be discharged into the interior of the second drain pipe 4 through the bypass pipe 5, and finally be discharged from the second drain pipe 4.

[0039] During the blocking process, due to the relatively high temperature of the sewage during the production process, when the sewage enters the bypass pipe 5, the thermometer 6 on the bypass pipe 5 will change and remind the staff. After seeing the temperature of the thermometer 6 rise, the staff can also touch the outer surface of the bypass pipe 5 with their hands. After feeling the temperature rise, it proves that the first sewage discharge pipe has been blocked, and thus the first sewage discharge pipe can be immediately cleaned.

[0040] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
