Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology and relates to a pipe structure suitable for ash removal systems. Background Technology

[0002] A dust removal system, also known as dust removal equipment or dust removal device, is a device that effectively removes dust and particulate matter from industrial equipment or the environment through specific working principles and mechanical structures. In large production workshops, the most common dust removal system is the pneumatic dust removal system. A pneumatic dust removal system is a device that uses air as the conveying medium and power source, mainly used to transport fine ash from the ash collection hoppers of boilers, flues, dust collectors, etc., to a storage location through pipes or other sealed devices.

[0003] The pneumatic ash removal system uses fluidized air to fluidize ash particles within the pipes, allowing them to be transported smoothly along the pipes. The exhaust gas duct is a key component; ash easily accumulates in long-term operation of the exhaust gas duct, requiring frequent shutdowns of the pneumatic ash removal system and manual cleaning of the ash buildup. This reduces the efficiency of the pneumatic ash removal system and increases the workload for personnel. Utility Model Content

[0004] The purpose of this invention is to provide a pipe structure suitable for ash removal systems, solving the problem that existing exhaust gas pipes are prone to ash accumulation, leading to reduced working efficiency of pneumatic ash removal systems and increased cleaning workload for personnel.

[0005] The technical solution adopted by this utility model is a pipe structure suitable for ash removal systems, including an air inlet pipe, a conveying pipe, and an air outlet pipe. The inlet end of the conveying pipe is connected to the outlet end of the air inlet pipe, and the outlet end of the conveying pipe is connected to the inlet end of the air outlet pipe. The angle between the air inlet pipe and the conveying pipe is 45° to 60°, and the angle between the conveying pipe and the air outlet pipe is 120° to 135°. The air inlet pipe and the air outlet pipe are arranged parallel to each other. A plurality of first spray heads are arranged at equal intervals along the vertical direction inside the air outlet pipe, and the plurality of first spray heads are connected to a water source through a pipe.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is in conjunction with the appendix Figure 1 The present invention will be described in detail with reference to specific embodiments:

[0023] A pipeline structure suitable for an ash removal system includes an inlet pipe 1, a conveying pipe 2, and an outlet pipe 3. The inlet end of the conveying pipe 2 is connected to the outlet end of the inlet pipe 1, and the outlet end of the conveying pipe 2 is connected to the inlet end of the outlet pipe 3. The inlet end of the inlet pipe 1 faces the air intake direction and is typically connected to a dust collector. The dust collector removes most of the dust, smoke, and other fine particulate matter from the air, and the remaining dust and smoke are absorbed by spray water after entering the pipeline. The outlet of the outlet pipe 3 is connected to an ash removal machine or a waste liquid tank to recover the spray water that absorbed the dust. A fan serves as the power source to supply air to the entire pipeline structure.

[0024] The angle between the inlet pipe 1 and the delivery pipe 2 is 45°–60°, and the angle between the delivery pipe 2 and the outlet pipe 3 is 120°–135°. The inlet pipe 1 and the outlet pipe 3 are arranged parallel to each other. This design makes the inlet end of the delivery pipe 2 higher than the outlet end, and the delivery pipe 2 is set at an angle. Dust entering from the inlet end of the delivery pipe 2 falls onto the pipe wall of the delivery pipe 2 and rolls into the outlet pipe 3 by gravity. Several first spray heads 4 are arranged at equal intervals along the vertical direction inside the outlet pipe 3. The several first spray heads 4 are connected to a water source through pipes. When the first spray heads 4 are turned on, the first spray heads 4 spray water into the outlet pipe 3. The sprayed water absorbs the dust, dirt and other small particles carried by the air in the outlet pipe 3.

[0025] The air outlet pipe 3 has several baffles 5 evenly spaced vertically inside, located below the first spray head 4. The baffles 5 are inclined, with an angle of 45° to 60° between them and the air outlet pipe 3. The number of baffles 5 is the same as the number of first spray heads 4. The spray water from the first spray head 4 falls onto the baffles 5, forming a waterfall. Each first spray head 4 and each baffle 5 works together to create multiple waterfalls inside the air outlet pipe 3. The 45° to 60° inclination angle increases the area of ​​the waterfalls. This increased area of ​​the waterfalls obstructs the downward flow of air, forcing air to pass through them. During this process, dust carried by the air is absorbed by the waterfalls, thus improving the efficiency of the spray water in absorbing dust.

[0026] The resulting waterfall, along with the baffle 5, can block the entire cross-section of the air outlet pipe 3. After removing the area blocked by the baffle 5, the waterfall will block the remaining unblocked portion, ensuring that the air must pass through multiple layers of waterfall filtration.

[0027] The delivery pipe 2 is equipped with a second spray head 6, which is connected to a water source through a pipe; when the second spray head 6 is turned on, spray water is sprayed out to wash the dust on the pipe wall of the delivery pipe 2.

[0028] A third spray head 7 is installed at the inlet of the conveying pipe 2, and the third spray head 7 is connected to a water source through a pipe. The spray water sprayed from the third spray head 7 absorbs the dust flowing into the air from the air inlet pipe 1, and the spray water falls onto the wall of the conveying pipe 2 and flows into the air outlet pipe 3 along the conveying pipe 2, while washing away the dust on the wall of the conveying pipe 2.

[0029] A fourth spray head 8 is installed at the outlet of the conveying pipe 2. The fourth spray head 8 is connected to a water source through a pipe. The spray water sprayed from the fourth spray head 8 adsorbs the dust flowing into the air from the conveying pipe 2 and washes the dust on the wall of the exhaust pipe 3.

[0030] The fourth spray head 8 is spaced 1 to 1.2 meters apart from the second spray head 6. Each of the two spray heads covers an area, avoiding repeated spraying of the same location and saving water and electricity costs.

[0031] The working principle of the dust removal system pipe structure provided by this utility model is as follows: the air carrying dust passes through the inlet pipe 1, the conveying pipe 2 and the outlet pipe 3 in sequence. At the connection of the two pipes, the dust hits the wall and falls. The dust in the conveying pipe 2 is washed by the spray water sprayed from the second spray pipe 6 and the third spray pipe 7 and flows into the outlet pipe 3 with the water. In the outlet pipe 3, the first spray pipe 6 and the baffle plate 5 form a water waterfall to absorb the dust again. Finally, the dust is completely absorbed by the spray water and is recycled and treated together with the water.

[0032] The advantage of the pipe structure of the dust removal system provided by this utility model is that, due to the angular relationship between the air inlet pipe 1, the conveying pipe 2 and the air outlet pipe 3, the conveying pipe 2 is set at an inclination. This not only allows the dust to fall off the wall at the pipe connection, but also forms a slope so that the spray water can wash the entire conveying pipe and prevent dust from accumulating inside the conveying pipe.

[0033] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
