What should I do if there is bubbling in the riser?

The pressure in the rising tube is unstable: it rises quickly and falls slowly
Adjust the fan suction force； Do not take them out too quickly in large numbers. Check that the bridge pipe, exhaust pipe, and intake pipe are unobstructed, ensuring there are three connections and one joint.
I think the process pipeline needs to be improved by adding a bypass and a tee at the outlet, which can prevent unidirectional leakage.
The pressure in the rising pipe is indeed difficult to control; I think the suction force of the fan should be adjusted
1. Adjust and stabilize the collector pipe pressure. 2. Reduce the resistance in the waste gas discharge system, and regularly clean equipment such as rising pipes, gas collection pipes, and primary coolers.

Reply to 1# xzc33218 regarding the “automatic control system for collector pipe pressure” – it is necessary to involve elements such as the “collector pipe flap”, “blower speed”, and “large circulation butterfly valve” in the control of collector pipe pressure in order to ensure its stability.
In this case, the adjustment capabilities of the fan are very limited; it is best to use a computer-based automatic control system to regulate the pressure in the collector duct.

Pressure fluctuations can \"spread\"; a pressure change in the gas collection pipe of one coke oven can cause changes in the pressure throughout the entire coal gas network of that coke oven. In the blast condensation section, Roots blowers are mostly used, and their flow rate remains relatively constant; therefore, when the amount of raw gas changes, it is easier for suction fluctuations to occur. As for the smoking issue? ? ? ? ? Smoking? It is recommended to increase the fan speed slightly to provide more suction head, thereby avoiding a situation where the fan’s suction power is insufficient. Under these conditions, adjusting the elbow butterfly valve to maintain stable pressure can play a certain role
Rising tube blowout is usually caused by high pressure in the gas collection system; in such cases, it is necessary to contact the control room and the drum cooler to increase the rotation speed, as well as to open the butterfly valves (those at the suction pipe and the circulation valves in the chemical production section). There may also be blockages in the bridge pipes, resulting in poor flow of waste gas; if the system has just been put into operation, it is necessary to check whether the counterweights are appropriate. As for the pressure of the gas collection pipe rising quickly and falling slowly, more instrument pressure guide tubes need to be considered.
When adjusting the pressure in the rising pipe, the range of adjustment should not be too large, as pressure regulation requires a time for reaction; it is necessary to understand this pattern. When there are pressure fluctuations, if the adjustment range is too large, it is easy for the cap to break off.
