Abstract

The invention discloses a high-temperature gas injection type insect killing method and device. According to the method, a high-temperature gas generation device (combustor) or an external combustor (the combustor is mounted at the front end of a centrifugal draught fan) is mounted in a rear end barrel body of an axial flow draught fan; the high-temperature gas generation device (combustor) uses fuel to combust to generate high-temperature gas, and the gas is blown out by a gas flow orientated driving device, namely the axial flow draught fan (the centrifugal draught fan); high temperature with the dozens or hundreds of degree centigrade is generated on target objects (insects); a high-temperature gas physical insect killing method is utilized so that bad influences caused by the fact that traditional pesticides and chemical medicaments are used for killing the insects of rice, melons and fruits, vegetables, nursery-grown plants and border trees, are avoided and the aim of killing the insects is realized.

Description

The jet disinsection method of high temperature and device

Background technology

The inventive method uses high-temperature gas physical method to kill the method for melon and fruit, vegetables, nursery stock, street tree insect, avoids the harmful effects such as environmental pollution that traditional agricultural chemicals and chemical agent bring, human body be poisoning.

Summary of the invention

Patent disclosure of the present invention a kind of high temperature jet disinsection method, the method installs high-temperature gas generating means (combustor) or external combustor (centrifugal fan is at front end install combustion machine) with in the cylindrical shell of axial flow blower rear end, this high-temperature gas generating means (combustor) uses fuel combustion to produce high-temperature gas, and by air-flow orientation drive-----axial flow blower (centrifugal blower) blowout at a high speed, in the upper generation tens of target object (insect) to several Baidu high temperature, reach the object eliminated destructive insects.

Accompanying drawing explanation

Fig. 1 is centrifugal high-temperature disinsection heating machine schematic diagram.

Fig. 2 is axial-flow type high-temperature disinsection heating machine schematic diagram.

The device that the inventive method uses is with a cylindrical outer casing 1(spiral case 1), the composition such as burner 2, axial flow blower (centrifugal blower) 3, air outlet 4, fuel oil (combustion gas) 5, control system 6, air inlet 7.

The method that this device produces high-temperature gas first starts coaxial blower fan 3(centrifugal blower 3), fuel 5 is measured according to the outlet temperature fuel (gas) of the air quantity of coaxial blower fan 3 and setting under the control of control system 6, fuel 5 is Thorough combustion in burner 2, burner 2 is equipped with hygrosensor at air outlet, temperature signal feeds back to controller 6, burner is made to provide certain heat to be sprayed by air outlet 7 on request, reconfigurable (the circular or rectangle of air outlet 7, multiple exit), special requirement also can make by particular/special requirement, select best jet angle and nozzle configuration in use, high-temperature gas is made to act on insect time long enough with it, temperature in pest body is made to raise lethal, plant leaf surface is not had a negative impact again.

This device can be made into portable by this principle as required, and vehicular is towed, can be widely used in vegetables, melon and fruit, flowers and trees, the various Pest killing such as moth, larva, adult of the plants such as street tree.

Claims
