Detailed Description
The utility model will be further explained with reference to the drawings.
As shown in figure 1, the waste gas tar removing device comprises a cooler 1 and a tar collector 2, wherein the inlet of the cooler 1 is a waste gas inlet 11, and the waste gas inlet 11 is used for allowing waste gas containing tar vapor to enter the cooler 1. For the convenience of connection, a flange may be provided at the exhaust gas inlet 11. The cooler 1 is provided with an inlet and an outlet for the cooling medium. The outlet of the cooler 1 is connected to the inlet of a tar collector 2, and the tar collector 2 is located below the cooler 1. In order to facilitate connection, the outlet of the cooler 1 is connected with the inlet flange of the tar collector 2, and the flange joint is provided with an asbestos pad, so that the sealing performance and the safety under long-term high temperature are ensured. The waste gas inlet 11 is positioned at the top of the cooler 1, the outlet of the cooler 1 is positioned at the bottom, the cooler 1 is preferably vertically arranged, and the tar vapor can automatically enter the tar collector 2 after being liquefied. The tar collector 2 is preferably disposed right below the cooler 1, so that the tar collector 2 collects tar formed by liquefaction of tar vapor. The bottom of the tar collector 2 is provided with a discharge valve 3, and the discharge valve 3 is used for discharging tar periodically or after reaching a certain amount. An outlet is arranged at the position from the middle part to the top part of the tar collector 2 and is connected with the inlet end of the gas transmission pipeline 4, wherein the position from the middle part to the top part of the tar collector 2 comprises the middle part and the top part of the tar collector 2. Set up updraft ventilator 5 on gas transmission pipeline 4, updraft ventilator 5 is used for making gas transmission pipeline 4 produce the negative pressure, for waste gas flow provides power, and gas transmission pipeline 4's end is exhaust outlet 41. In order to facilitate connection, the two ends of the air draft device 5 are connected with the air transmission pipeline 4 through flanges, and asbestos gaskets are arranged at the joints of the flanges respectively, so that the sealing performance and the safety under long-term high temperature are guaranteed. One or more valves, such as solenoid valves or pneumatic valves, may also be provided in the gas line 4 to facilitate automatic control.
Since the gas flowing out from the outlet of the tar collector 2 still contains a part of tar vapor, the waste gas further dissipates heat through the subsequent gas transmission pipeline 4, and a small amount of tar is generated. In order to further collect tar and improve the decoking rate, at least one secondary tar collector 6 is also arranged on the gas transmission pipeline 4 in series. The secondary tar collector 6 and tar collector 2 are identical in construction, but may have a volume less than that of tar collector 2. The secondary tar collector 6 is used for collecting tar liquefied in the gas transmission pipeline 4, so the secondary tar collector 6 is also preferably vertically arranged, an inlet is arranged at the top of the secondary tar collector 6, and the gas transmission pipeline 4 at the inlet of the secondary tar collector 6 is also vertically arranged. An outlet is provided from the middle to the top of the secondary tar collector 6 or at the inlet of the secondary tar collector 6 and the vertically arranged gas transmission pipe 4, see fig. 1. The bottom of the secondary tar collector 6 is provided with a discharge valve 3, and the discharge valve 3 is used for discharging the collected tar. The tar content of the flue gas decreases gradually in the direction of the gas flow, and therefore the secondary tar collector 6 should be arranged as close as possible to the inlet end of the gas duct 4. The secondary tar collector 6 may be provided in one or more quantities, the specific quantities being determined according to the tar vapor content in the exhaust gas.
Under the condition that the waste gas removes tar device and sets up secondary tar collector 6, in order to improve the flexibility of waste gas removes tar device, the entry end of gas transmission pipeline 4 still connects the branch pipe, sets up the valve on the branch pipe, and the exit end of branch pipe is connected to 5 front sides of updraft ventilator of gas transmission pipeline 4. The valves on the branch pipes are closed, and the waste gas can only pass through the secondary tar collectors 6 along the gas transmission pipeline 4 in sequence and then enters the exhaust device 5; and opening the valve on the branch pipe, and closing the valve on the gas transmission pipeline 4, so that only the tar collector 2 actually participates in tar collection, and each secondary tar collector 6 does not participate in tar collection at all. On the basis, the outlet of each secondary tar collector 6 is respectively connected with a branch pipe, a valve is arranged on each branch pipe, and the outlet end of each branch pipe is connected to the front side of the air draft device 5 of the gas transmission pipeline 4. The number of the secondary tar collectors 6 participating in tar collection can be selected by adjusting the valve, so that flexible adjustment is facilitated.
