Description

Technical Field

[0001] This utility model relates to the technical field of coal gasification equipment, and more specifically to an anti-clogging electrostatic tar removal pipe. Background Technology

[0002] Electrostatic precipitator is a core piece of equipment in coal gasification systems. It captures tar, dust, and small amounts of oily water droplets in the coal gas, thereby cleaning and purifying it. However, during coal gas production, due to the cold winters in northern regions, the tar collected by the electrostatic precipitator and dust collector can solidify and clog pipes during discharge, accumulating in the operating equipment. This prevents the purification equipment from operating normally, increases the pressure at the furnace outlet and bottom, causes a sharp drop in gas production, deteriorates furnace conditions, shortens the start-up cycle, forces shutdowns for maintenance, increases maintenance costs, and poses significant safety hazards. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing an anti-clogging electrostatic tar removal pipe, which effectively solves the problem of solidification in electrostatic tar removal and electrostatic dust removal tar discharge pipes.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: an anti-clogging electrostatic tar removal pipe, comprising an electrostatic tar remover tank and a steam pipe, wherein the steam pipe is connected through the electrostatic tar remover tank, and a tar discharge pipe is connected to the outer wall of the electrostatic tar remover tank. A valve is installed in the middle of the tar discharge pipe. The two ends of the steam pipe located outside the electrostatic tar remover tank are a steam inlet and a steam outlet, respectively. A heat tracing pipe is fixedly sleeved on the outer side of the tar discharge pipe, located between the valve and the electrostatic tar remover tank. An air inlet pipe and an air outlet pipe are fixedly connected to the outer wall of the heat tracing pipe, and the air inlet pipe is connected to the steam outlet.

[0005] To facilitate control of the steam flow and direction, as a preferred embodiment of the anti-clogging electrostatic tar removal pipe of this utility model, a valve two is provided on the outside of the steam outlet, and a steam exhaust pipe is connected to one end of the steam outlet pipe located outside the heat tracing pipe, with a valve three installed in the middle of the steam exhaust pipe.

[0006] To facilitate the disassembly of the inlet and outlet pipes and subsequent maintenance of the heat tracing pipe cavity, the steam outlet and the inlet pipe are detachably connected via a flange, and the outlet pipe and the exhaust steam pipe are detachably connected via a flange, as preferred embodiments of the anti-clogging electrostatic tar removal pipe of this utility model.

[0007] To facilitate maintenance of the steam pipe inside the electrostatic precipitator tank, a manhole is provided on the outer side of the electrostatic precipitator tank as a preferred anti-clogging electrostatic tar removal pipe of this utility model.

[0008] In order to increase the contact area between the air inside the electrostatic precipitator tank and the steam pipe, the steam pipe, which is the preferred anti-clogging electrostatic tar removal pipe of this utility model, has a serpentine shape inside the electrostatic precipitator tank.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The heat tracing pipe cavity is connected to the outside of the tar discharge pipe. When steam enters the heat tracing pipe cavity, it can evenly wrap the entire tar discharge pipe to keep the inside of the tar discharge pipe warm and prevent it from solidifying and blocking the tar discharge route.

[0011] 2. When the steam pipe, heat tracing pipe, and steam exhaust pipe need to be inspected separately, close valve two to stop the steam from being delivered to the heat tracing cavity, and then disassemble the flanges at the ports of the inlet and outlet pipes respectively, so that the staff can inspect the relevant pipes separately.

[0018] Please see Figure 1-3 The present invention provides the following technical solution:

[0019] An anti-clogging electrostatic tar removal pipe includes an electrostatic tar remover tank 1 and a steam pipe 2. The steam pipe 2 is connected to the electrostatic tar remover tank 1 through the tank. A manhole 101 is provided on the outside of the electrostatic tar remover tank 1. A tar discharge pipe 102 is connected to the outer wall of the electrostatic tar remover tank 1. A valve 103 is installed in the middle of the tar discharge pipe 102. The steam pipe 2 is located inside the electrostatic tar remover tank 1 and has a serpentine structure.

[0020] The steam pipe 2 is located at two ends on the outside of the electrostatic precipitator tank 1, namely steam inlet 201 and steam outlet 202. The outer side of the tar discharge pipe 102 is fixedly sleeved with a heat tracing pipe 3. The heat tracing pipe 3 is located between valve 103 and the electrostatic precipitator tank 1. The outer wall of the heat tracing pipe 3 is fixedly connected to an air inlet pipe 301 and an air outlet pipe 302. The air inlet pipe 301 is connected to the steam outlet 202.

[0021] In this embodiment: a steam pipe 2 is installed inside the electrostatic precipitator. The steam pipe 2 is serpentine to increase the temperature of the environment around the tar at the bottom of the electrostatic precipitator tank 1 (electrostatic tar collector). The tar is discharged through the tar discharge pipe 102. The valve 103 can control the amount of tar discharged. During the discharge process, steam enters the serpentine part through the steam inlet 201 of the steam pipe 2, and then enters the cavity of the heat tracing pipe 3. The cavity of the heat tracing pipe 3 is sleeved on the outside of the tar discharge pipe 102. When the steam enters the cavity of the heat tracing pipe 3, it can evenly wrap the entire tar discharge pipe 102 to keep the inside of the tar discharge pipe 102 warm and prevent it from solidifying and blocking the tar discharge route.

[0022] As a technical optimization of this utility model, a valve 203 is provided on the outside of the steam outlet 202, and the end of the steam outlet pipe 302 located outside the heat tracing pipe 3 is connected to the steam exhaust pipe 4, and a valve 401 is installed in the middle of the steam exhaust pipe 4.

[0023] In this embodiment, valves are installed at the inlet and outlet of the steam pipe 2 into the cavity of the heat tracing pipe 3 to control the flow and direction of steam, making it easier for staff to shut down the steam pipe 2 and disassemble the pipe.

[0024] As a technical optimization of this utility model, the steam outlet 202 and the air inlet pipe 301 are detachably connected by a flange, and the air outlet pipe 302 and the steam exhaust pipe 4 are detachably connected by a flange.

[0025] In this embodiment, the steam inlet and outlet of the cavity of the heat tracing pipe 3 are connected to the steam pipe 2 and the steam exhaust pipe 4 respectively through flanges. The flange design allows the staff to easily disassemble the steam pipe 2 and the steam exhaust pipe 4, thereby facilitating the maintenance of the relevant pipelines.

[0026] The working principle and usage process of this utility model are as follows: When the electrostatic precipitator tank 1 is normally discharging tar, valve 103 is opened, and the tar is discharged outward through the tar discharge pipe 102. At the same time, valves 203 and 401 are opened to allow steam to enter the cavity of the heat tracing pipe 3, thereby heating and insulating the surface of the tar discharge pipe 102 so that the tar can be discharged normally. In addition, the steam flow rate in the heat tracing pipe 3 can be controlled by adjusting the valve size, thereby controlling the temperature of the tar discharge pipe 102. When the steam pipe 2, heat tracing pipe 3, and steam discharge pipe 4 need to be inspected separately, valve 203 is closed to stop the steam from being delivered to the heat tracing cavity. Then, the port flanges of the inlet pipe 301 and outlet pipe 302 are disassembled respectively, thereby disassembling and separating the steam pipe 2, heat tracing pipe 3, and steam discharge pipe 4 for inspection.

[0027] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
