Turbine flowmeter monitoring module

Abstract

The invention discloses a turbine flowmeter monitoring module which comprises a gas collecting well, a gas analyzer, a flow monitoring and adjusting device, a gas conveying pipeline, a control center and an internal combustion generator set. The flow monitoring and adjusting device comprises a turbine flowmeter and a signal end; the turbine flowmeter comprises a shell, a flow guide plate, an impeller and a rotating plate. A fixing part is mounted at one end, close to the impeller, of the guide plate; the control center is used for receiving data, collected by the gas analyzer, of the content of each component of the landfill gas, the flow rate and flow information of the landfill gas in the gas conveying pipeline is obtained according to the received data and the signal end, the flow monitoring and adjusting device is controlled, the extraction speed of the landfill gas is adjusted, and the dead well phenomenon is avoided; the two ends of the impeller are supported through the sleeve, meanwhile, the impeller is axially positioned through the ball, when the impeller is damaged, after the rotating plate is opened, the impeller can be separated from the flow guide plate by sliding the sleeve, and maintenance of the impeller is facilitated.

Description

technical field [0001] The invention belongs to the technical field of electrical control, in particular to a turbine flowmeter monitoring module. Background technique [0002] At present, the main treatment method of domestic waste is landfill. After a long period of accumulation of domestic waste in landfills, a large amount of landfill gas, mainly methane, is produced. If the landfill gas is not treated accordingly, it will be released into the atmosphere and pollute the surrounding air. Moreover, biogas is a flammable and explosive gas, which poses a safety hazard when it is emitted into the atmosphere. At present, there are two ways to deal with landfill gas. The first one is to collect the landfill gas through the gas collection well and transport it to the incineration tower for incineration after pretreatment; the second one is to landfill the garbage collected in the gas collection well. After pretreatment, the gas is sent to the internal combustion engine unit f...

Problems solved by technology

The operator of this extraction method needs to go to the gas gathering wellhead to obtain gas samples in person, which has a low safety factor, and the manual operation speed is slow, requiring high labor costs.

Moreover, when maintaining the turbine of the existing turbine flowmeter used to detect the flow of landfill gas, it is necessary to remove the deflectors at both ends of the turbine, and then remove the impeller as a detection component, which is complicated and time-consuming.
