Description

Technical Field

[0001] This utility model relates to the field of high-voltage electric field separation, specifically a tar collection device for use at the tar outlet of an electrostatic precipitator with automatic alarm capability, and an electrostatic precipitator having the tar collection device. Background Technology

[0002] Electrostatic precipitators can be used to collect tar from roasting flue gas and asphalt melting flue gas. The tar outlet of the electrostatic precipitator is equipped with a conical temporary storage hopper. The tar produced by the electrostatic precipitator enters the temporary storage hopper. The external discharge valve of the temporary storage hopper is opened manually at regular intervals to discharge the tar into a tar barrel, which is then transported for further processing.

[0003] The viscosity of tar increases as temperature decreases, especially in winter when it significantly increases, making the drain valve prone to clogging. This results in poor tar drainage, with inconsistent flow rates, and frequent spillage of tar onto the surface of tar containers and the ground. Tar's high permeability means that even with timely cleaning, oil stains remain on the ground, posing a challenge to environmental protection efforts. Furthermore, the temporary storage hopper only has a storage function; once it is full of tar or reaches its designed level, it does not automatically stop the flow of tar into the hopper or trigger an alarm, thus posing a certain risk.

[0004] Patent CN 222490463 U discloses a heating and discharge device for an electrostatic precipitator, including a slag discharge port. A ceramic heating rope is uniformly wound around the outer wall of the slag discharge port, heating the port and solving the problem of difficult tar discharge. While this heating and discharge device addresses the issue of increased tar viscosity, it does not solve the problems of not automatically stopping tar from entering the discharge port when it is full or reaches the designed liquid level, nor does it provide an automatic alarm. Utility Model Content

[0005] This invention first provides an automatic alarm-enabled tar collection device, which solves the problems of not being able to automatically stop the process of tar entering the storage tank after the storage tank is full of tar or reaches the design liquid level, and not being able to automatically alarm.

[0006] The technical solution adopted by this utility model is: an automatic alarm tar collection device, including a storage box, an oil inlet at the top of the storage box, an oil outlet at the bottom of the storage box, an oil discharge valve at the oil outlet, an alarm on the outside of the storage box, an air pressure balance hole at the top of the storage box, a connecting rod inside the air pressure balance hole, a float at the end of the connecting rod inside the storage box, and a switch of the alarm at the end of the connecting rod outside the storage box, and the air pressure balance hole can be blocked when the float rises to the highest position.

[0007] To facilitate the connection between the oil inlet of the storage tank and the oil outlet of the temporary storage hopper of the electrostatic precipitator, or the oil outlet of the electrostatic precipitator, a flange joint is further provided at the end of the oil inlet of the storage tank.

[0008] In order to manually block the process of tar entering the storage tank, an oil inlet valve is installed at the oil inlet of the storage tank.

[0009] To facilitate the emptying of the tar from the storage tank, the bottom plate of the storage tank is tilted, and the oil discharge port is located at the lowest point of the storage tank.

[0010] To prevent tar from overflowing from the pressure balance hole, a further step is to install a pressure balance pipe on the top of the storage box, which connects the inside of the storage box to the outside, with a connecting rod passing through the pressure balance pipe.

[0011] To prevent the tar inside the storage tank from becoming viscous due to low temperatures and affecting its discharge, a heating device is further installed on the outside of the storage tank.

[0012] Since tar adheres more easily to the bottom plate of the storage box than to the side plates, the heating device is further positioned on the outside of the bottom plate of the storage box.

[0013] For ease of control of the heating device, specifically: the heating device is an electric heating device, and the electric heating device is equipped with an automatic power-off module.

[0014] This utility model also provides an electrostatic precipitator for tar collection, which solves the problem that the electrostatic precipitator cannot automatically alarm when the tar storage is full. The electrostatic precipitator includes any of the above-mentioned tar collection devices with automatic alarm capability. The tar outlet of the electrostatic precipitator is connected to the oil inlet of the storage tank, or the tar outlet of the electrostatic precipitator is provided with a conical temporary storage hopper, and the oil outlet of the temporary storage hopper is connected to the oil inlet of the storage tank.

[0015] To prevent the tar in the storage hopper from becoming viscous due to low temperature and affecting its discharge, a heating coil is installed on the outer wall of the storage hopper.

[0016] The beneficial effects of this invention are as follows: The oil inlet of the storage tank is connected to the oil outlet of the temporary storage hopper of the electrostatic precipitator, or the oil inlet of the storage tank is directly connected to the oil outlet of the electrostatic precipitator. Because the top of the storage tank is equipped with a pressure balance hole, tar can smoothly enter the storage tank. After the tar in the storage tank reaches the designed liquid level, the float rises and drives the connecting rod to rise synchronously. The connecting rod is connected to the switch of the alarm, causing the alarm to sound an alarm signal. When the float rises to its highest position, it blocks the pressure balance hole, automatically stopping the process of tar entering the storage tank. After the tar in the storage tank is discharged through the oil discharge port, the float automatically descends and opens the pressure balance hole, allowing the tar to re-enter the storage tank. The float is connected to the end of the connecting rod located inside the storage tank, preventing the float from moving arbitrarily within the storage tank, ensuring the stability and reliability of the float.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This utility model's automatic alarm-equipped tar collection device is used to connect to the oil outlet of the temporary storage hopper 9 of an electrostatic precipitator, or to the oil outlet of the electrostatic precipitator, to temporarily collect the tar produced by the electrostatic precipitator. See also... Figure 1 The tar collection device with automatic alarm function includes a storage tank 1. The top of the storage tank 1 has an oil inlet, which connects to the drain port of the temporary storage hopper 9 of the electrostatic precipitator, or to the outlet port of the electrostatic precipitator. The storage tank 1 is generally made of steel plate. For easy connection of the oil inlet, a flange joint is provided at the end of the oil inlet of the storage tank 1. To allow manual interruption of tar entry into the storage tank 1, an oil inlet valve 6 is provided at the oil inlet. For easy installation of the oil inlet valve 6, flange joints are provided at both ends of the oil inlet valve 6. The bottom of the storage tank 1 has an oil discharge port, at which an oil discharge valve 2 is provided. For easy installation of the oil discharge valve 2, flange joints are provided at both ends of the oil discharge valve 2. To facilitate the emptying of tar from the storage tank 1, the bottom plate of the storage tank 1 is inclined, and the oil discharge port is located at the lowest point of the storage tank 1.

[0021] The tar inside storage tank 1 becomes viscous at low temperatures, affecting its discharge. To address this issue, a heating device 8 is installed on the outside of storage tank 1. For ease of control, the heating device 8 is typically an electric heating device. To prevent overheating of storage tank 1, the heating device is equipped with an automatic power-off module, which automatically shuts off the electric heating device when the heating temperature reaches the set maximum temperature. For example, the automatic power-off module automatically shuts off the electric heating device after heating to 30°C. Because tar adheres more easily to the bottom plate of storage tank 1 than to the side plates, the heating device 8 is generally located on the outside of the bottom plate of storage tank 1, such as... Figure 1 As shown.

[0022] An alarm is installed on the outside of storage box 1. This alarm can be a light alarm, a sound alarm, or a combination of both. The alarm can be installed directly on storage box 1 or not. A pressure balancing hole is located on the top of storage box 1. This hole is used to balance the internal pressure of storage box 1 when tar enters. To prevent tar from overflowing from the pressure balancing hole, the hole should be positioned as high as possible, for example, see [reference needed]. Figure 1 The top of the storage box 1 is equipped with an air pressure balance pipe 7. Both ends of the air pressure balance pipe 7 are open, and the air pressure balance pipe 7 connects the inside of the storage box 1 with the outside world, forming an air pressure balance hole.

[0023] A connecting rod 3 is installed inside the pressure balance hole, with a gap between the connecting rod 3 and the hole wall. One end of the connecting rod 3 is located inside the storage tank 1, and the other end is located outside the storage tank 1. To prevent the connecting rod 3 from falling into the storage tank 1, a limiting device or a bent shape is provided at the end of the connecting rod 3 located outside the storage tank 1. The end of the connecting rod 3 inside the storage tank 1 is connected to a float 4, and the end of the connecting rod 3 located outside the storage tank 1 is connected to the switch 5 of the alarm. When the float 4 rises, the connecting rod 3 rises synchronously and can trigger the switch 5 of the alarm. When the float 4 rises to its highest position, it can also block the pressure balance hole, thereby automatically blocking the process of tar entering the storage tank 1. When a pressure balance pipe 7 is installed at the top of the storage tank 1, the connecting rod 3 passes through the pressure balance pipe 7, and when the float 4 rises to its highest position, the float 4 can enter the lower end of the pressure balance pipe 7.

[0024] When storage tank 1 is full of tar, the float rises to its highest point, triggering the alarm switch 5 on connecting rod 3. The alarm then sounds, alerting the operator. Upon arrival, the operator closes the inlet valve 6 and, depending on the tar's viscosity, decides whether to activate the heating device 8. The tar drum is placed below the unloading valve 2, and the valve is opened to drain the tar. After storage tank 1 is empty, the unloading valve 2 is closed, and the inlet valve 6 is opened to begin the next cycle. Ideally, the tar drum should be slightly larger than storage tank 1 to prevent tar overflow.

[0025] This utility model also provides an electrostatic tar precipitator. For example... Figure 1 As shown, the electrostatic precipitator includes the aforementioned tar collection device with automatic alarm capability. The tar outlet of the electrostatic precipitator is equipped with a conical temporary storage hopper 9, and the oil outlet of the temporary storage hopper 9 is connected to the oil inlet of the storage tank 1. Alternatively, the electrostatic precipitator includes the aforementioned tar collection device with automatic alarm capability, and the tar outlet of the electrostatic precipitator is connected to the oil inlet of the storage tank 1. To prevent the tar in the temporary storage hopper 9 from becoming viscous due to low temperature and affecting its discharge, a heating device, such as a heating coil 10, is provided on the outer wall of the temporary storage hopper 9.
