Problems solved by technology

However, the patent does not deal with the fact that the sampling pump will be blocked by dirt in the flue gas
With the accumulation of dust on the sampling pump until it is blocked, it is easy to cause the sampling pump to burn out, resulting in a chain reaction of the system and economic losses

Embodiment Construction

[0028] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0029] Such as figure 1 As shown, an automatic flue gas monitoring system with flow alarm control includes a sampling pump 1, a rotameter 2 and a controller 3, the rotameter 2 is connected to the output end of the sampling pump 1, and the rotameter 2 is connected to the sampling The pump 1 is connected to the controller 3, and the controller 3 can control the opening and closing of the sampling pump 1 and the rotameter 2. The controller 3 is a PLC controller.

[0030] Specifically, the flue gas automatic monitoring system with flow alarm control also includes a capacitive proximity switch 4, which is set at 0.2-0.5L of the float flowmeter 2, and the input of the capacitive proximity switch 4 and the controller 3 end connected. The float flowmeter 2 includes a floating ball, and the capacitive proximity switch 4 is triggered to generate an opening signal w...

Abstract

The invention provides an automatic fume monitoring system with flow alarm control and a method of the automatic fume monitoring system. The automatic fume monitoring system comprises a sampling pump, a floater flowmeter and a controller, wherein the floater flowmeter is connected with the output end of the sampling pump; the floater flowmeter and the sampling pump are connected with the controller; the controller is used for controlling opening and closure of the sampling pump and the floater flowmeter; and a capacitive approach switch is arranged on the floater flowmeter. By adopting the automatic fume monitoring system, the flow of fume inside a sampling pump outlet flue is monitored in real time, and an alarm system can be powered on and the sampling pump can be switched off if the fume flow is too small, that is, the sampling pump is blocked by granules and dust for a certain time, and thus the sampling pump can be prevented from being damaged because of blocking.

Description

technical field [0001] The invention belongs to the technical field of flue gas detection, and in particular relates to an automatic flue gas monitoring system with flow alarm control and a method thereof. Background technique [0002] The automatic flue gas monitoring system can be used for real-time sampling and detection of the flue gas that needs to be discharged into the atmosphere in industrial production, so as to avoid the discharge of toxic and harmful gases to the outside world and pollute the environment. [0003] The existing automatic flue gas monitoring system usually includes a flue gas collector, a pretreatment system, a gas analysis device, a controller, and the like. Where the flue gas enters the gas analysis device, the flue gas in the flue must be transmitted to the analysis instrument through a sampling pump. In order to meet the needs of the analytical instrument for the pumping volume, the sampling pump must ensure sufficient flow and pressure, and no...
