Abstract

The invention relates to agriculture, in particular to devices for disinfecting industrial premises of large volumes, for example, livestock breeding. The purpose of the invention is to increase the productivity and quality of disinfection during the treatment of large volumes of premises. The plant for disinfection of agricultural premises consists of an aircraft gas turbine engine 1 and an ejector device 3, which are installed with the possibility of forming an adjustable ring slit for air leaks and temperature control in an ejector device. The ejector device 3 is equipped with a disinfection solution supply system, which includes a tank, a pump, a pipeline, and a reverse spring loaded valve installed outside the limits of the ejector device. The valve prevents solution from entering the ejector device when the pump is turned off and the ejector device is warming up. 2 Il. cl

Description

Fig. /

The invention relates to agriculture, in particular to devices for disinfecting industrial premises of large volumes, for example livestock.

The purpose of the invention is to improve the performance and quality of disinfection in the treatment of large volumes of premises.

FIG. 1 shows a diagram of an installation for disinfecting agricultural premises; figure 2 - ejector device with the supply system disinfectant solution.

The plant for disinfection of agricultural premises contains an aviation gas turbine engine 1 placed on the vehicle 2 together with an ejector device 3 and a dispensing system for disinfectant preparation.

The ejector device 3 consists of the inlet part 4, the mixing chamber 5 and the outlet part 6. The inlet part 4 of the ejector device 3 together with the output device 7 of the gas turbine engine 1 forms an annular adjustable slit A.

The dosing supply system of the preparation contains a preparation tank 8, an injection pump 9, a pipeline 10, an atomizer 11 with outlet openings located in the mixing chamber 5 of an ejector device. The dosing system is equipped with a shut-off unit containing a spring-loaded valve 12, placed outside the ejector device on the additional pipeline 13 and connected to the pipeline 10 directly at the spray gun 11.

Installation for disinfection of agricultural premises works as follows.

During operation of the gas turbine engine 1, exhaust gases are directed from the output device 7 to the inlet part 4 of the ejector device 3, where external air is drawn in (ejected). In the mixing chamber 5 of the ejector device, the temperature of the gas-air flow is equalized, and in the output part 6 - reduction flow rates. The high-velocity gas-air flow leaving the ejector device 3 is directed to the treated room. After switching on the pump 9, the preparation is pumped from the tank 8 through the pipeline 10 to the sprayer 11 and through the outlets into the mixing chamber 5. When this spring-loaded valve 12 pressure on 5

the oppressive fluid is kept in a closed state and does not affect the drug delivery process. As a result of the interaction supplied through

a spray of a liquid preparation with a high-speed hot gas-air flow in the mixing chamber 5 results in the formation of fine aerosols with partial evaporation of liquid droplets.

0 Dosing of the drug according to the volume of the treated room is carried out by changing the duration and mode of operation of the pump 9.

After disconnecting the pump 9 pressure

5, the fluid in the pipe 10 falls, the spring-loaded valve 12 opens and communicates with the atmosphere through an additional pipe 13 to the internal cavity of the pipe 10, the remaining

In the pipeline 10, the preparation flows into the tank 8, and the volume released in the pipeline is filled with air with a pressure close to atmospheric, which excludes the possibility of the drug being sucked into the mixing chamber 5 of the ejector device 3 due to the low pressure in it.

The required gas-air flow temperature and its flow rate at the outlet of the installation are provided by selecting the operating mode of the gas turbine engine 1 and changing the flow area of the annular adjustable gap A between the output device 7 of the gas turbine engine and

5 input part 4 ejector device. The proposed implementation of an installation for disinfecting agricultural premises allows to increase the productivity and quality of disinfection during

0 processing of large volumes of rooms by using an aviation gas turbine engine as a gas generator and combined with an adjustable ejector device and a dosing system for delivering the preparation. Equipping the dosing system with a shut-off unit made in the form

The 5 mounted outside of the mixing chamber on the additional pipeline of the spring-loaded valve for communicating the cavity of the pipeline with the atmosphere eliminates the possibility of the drug leaking into
