Embodiment Construction

[0026] 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).

[0027] 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

A Venturi of a multi-concentration control unit, comprising a Venturi tube (3), and a liquid inlet (7) connected to the throat of the Venturi tube (3), characterized in that: the Venturi tube (3) is divided into Half part (20) and Venturi tube lower half (21), wherein the Venturi tube upper half (20) and Venturi tube lower half (21) are connected by threaded interface (16), set in the middle part of Venturi tube (3) There is a baffle (13), and the liquid inlet (7) enters the inside of the Venturi tube (3) through a hole in the lower half of the Venturi tube (21), and a nozzle (17) is provided at the end of the liquid inlet (7) , the center of the nozzle pipe (17) facing up to the baffle plate (13). The beneficial effect is: through the indication of the indication circuit (26), the composition, concentration and flow rate of the dust-laden gas (6) can be visually observed, which is convenient for staff to operate and control.

Description

technical field [0001] The present invention relates to the field of gas processing devices, in particular to a Venturi of a multi-concentration control unit, and also relates to a method for controlling the Venturi of a multi-concentration control unit. 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...
