Embodiment Construction

[0024] Such as figure 1 As shown, the Venturi is connected with the centrifugal separator (2) in use, and the dusty gas (6) passes through the Venturi tube (3), and then enters the centrifugal separator (2) through the airflow regulator (4), A racemator (1) is provided at the bottom of the centrifugal separator (2). A liquid inlet (7) is connected to both ends of the throat on the Venturi tube (3).

[0025] In order to measure the flow rate and composition of the gas in the dusty gas (6), a flow sensor (22) and an infrared gas sensor (23) are arranged at the inlet of the Venturi tube (3), and the flow sensor (22) and the infrared gas sensor (23) ) are respectively connected with the controller (24), and the controller (24) displays the gas flow rate and concentration through the indicating circuit (26). When the gas flow rate measured in the flow sensor (22) is faster, the indicator circuit (26) will The faster the flashing frequency of the indicator light, when the gas con...

Abstract

The invention relates to a multi-concentration control venturi and a control method thereof. The venturi comprises a controller, a liquid inlet tube solenoid valve, a first liquid solenoid valve, a second liquid solenoid valve and an indication circuit; and the venturi is characterized in that the first and second liquid solenoid valves, the liquid inlet tube solenoid valve and a third liquid solenoid valve are in signal connection with a controller, the controller determines the component, concentration and flow velocity of dust included gas in the venturi according to information back fed bya flow sensor and an infrared gas sensor, and the first, third and second liquid solenoid valves are adjusted to prepare a gas state optimized liquid. Power of the controller is from a power supply module, and the indication circuit receives information feedback from the controller. The venturi and the control method have the advantages that the component, concentration and flow velocity of the dust included gas in the venturi via indication of the indication circuit, and convenience is provided for operation and control of workers.

Description

technical field [0001] The invention relates to the field of gas processing devices, in particular to a venturi with multi-concentration control, and a method for controlling the venturi with multi-concentration control. Background technique [0002] Venturi is the dust collector with the highest dust removal efficiency in the scrubber, and it is widely used. The atomized gas ejected from the liquid during use is positively correlated with the dust removal effect. The wet dust collector is a device that makes the dust-containing gas and liquid come into close contact, and uses the collision of water droplets and particles and other effects to capture dust or increase the particle size. Venturi scrubber is a kind of wet dust collector, which is a high-efficiency dust collector and is often used for cooling and dust removal of high-temperature flue gas. [0003] There are many factors that affect the performance of the Venturi scrubber, among which the dispersion of the spray...
