Description

(54) LIQUID DISPENSER: TAYS AND GASES

one

 The invention relates to dosing devices and can be used in the chemical, coking and other industries;

Known dispenser for liquids and gases,

containing a cylindrical housing with openings for inlet through tubes, a cylindrical rotor with a shaft and tubes for withdrawal of the mixture. However, this dispenser does not have sufficient sensitivity and reliability in operation.

In order to eliminate these drawbacks, in the proposed dispenser, the rotor has an internal chamber with an opening, with a 5 ”alternating with the openings of the housing.

In order to increase the mass-transfer surface, the rotor chamber can be made in the form of a rhombus.

FIG. 1 is a schematic diagram of the dispenser; in fig. 2 - section along

A-A in FIG. one; Fig. 3 is a circuit for connecting the dispenser to the gas and liquid lines.

The analyzed gas from the source comes under its own pressure to the total 1

the dispenser collector 1 and be returned to the circulation gas line again, but to a point with a pressure less and sufficient to form a pressure difference as a flow driver. The branches 2 from the collector are led to the cylindrical: the body 3 of the dispenser-absorbent at points i located in a vertical plane to the body. In the same plane, pipes 4 and 5 are discharged, diverting gas and liquid, respectively. Inside the housing there is a rotor 6 with an inner chamber 7, a bore-hole 8, chambers 9 i counter-pressure, with apertures a, a tube 10 for taking a pressure pulse. The dispenser housing is sealed with a cover 11 with a cylindrical recess 12 for the rotor shaft 13.

A tube 5 is connected to the lower opening b in the dispenser housing to dispense the mixture .phases. On the forks of the rotor) 1 pulley is set 14. The liquid phase, which employs a means of accumulating and transmitting information about the concentration of the component to be determined in the gas

; 3; :

the mixture (the target gas to be analyzed is analyzed) is supplied through pipe 15,

The dispenser works as follows.

Pulsed dosing of media occurs during the rotation of the rotor. Typically, the cycle begins with the output of the mixture of the two phases, which are calculated in contact. The delivery time of the mixture, as well as the arrival time of the caled from the phases, completely depends on the rotor speed and diameters of the cross sections of the inlet holes, the response of the effects 2 and the tube 15, made when required in an ellipse, the longitudinal axis of the symmetry of which corresponds to the rotation direction of the rotor.

In the case of a ro-rhenia, a ro-rum is dosed;, and the medium in the required volumetric 1; most, the CAT depends on the size of the inlet, the flow time, the crust, the viscosity, the temperature, etc. The remaining volume of chamber 7 enters the gas phase. This establishes a strict ratio of volumes of media. In the chamber (7, the process of sorption of the measured component from the gas mixture proceeds.

As the rotor rotates further, the gas is emitted into the appropriate line and then when the opening of the gas inlet tube is aligned with the tube inlet in the rotor, the new chamber 7 is filled with a new portion of gas. Gas Filling and Emission Cycles

mixtures are repeated in proportion to the number of inlet and outlet openings. In this case, the liquid phase zs. each full revolution is admitted only once and is released once with a mixture of both

phases.

Claims (2)

1. A liquid and gas metering unit, a cobalt cylindrical body with openings Å. 1 I for supplying the medium pipes, a cylinder with a shaft and a tube for blending, which differs By the fact that, in order to increase the sensitivity and reliability of the dispenser, the rotor has an internal chamber with an opening that is alternately aligned with the openings of the housing. 2. The dispenser according to claim 1, d and t, a. This is due to the fact that, in order to increase the mass transfer surface, the rotor chamber is made in the form of a rhombus.
