Method for controlling flue gas temperature of spray pipe of thermal fogger and self-propelled impulse type thermal fogger

Abstract

The invention relates to a method for controlling flue gas temperature of a spray pipe and a self-propelled impulse type thermal fogger adopting the method. The method comprises the steps of arranging an isolating layer between a flue gas spray pipe and an environment, and injecting different isolating media into the isolating layer in accordance with different requirements of different pesticides on the temperature adaptability. The self-propelled impulse type thermal fogger comprises a chassis drive, a machine frame, a double-layer spray pipe, a pesticide box, a fuel tank, a filling system, an automatic temperature control system, an engine and a remote control system, wherein the machine frame is arranged on the chassis drive, the double-layer spray pipe is arranged at the front part of the machine frame, the pesticide box, the fuel tank, the filling system and the automatic temperature control system are arranged at the middle part of the machine frame, and the engine and the remote control system are arranged at the rear part of the machine frame; the automatic temperature control system comprises a temperature sensor and a temperature controller; the spray pipe is of an inner-outer double-layer structure, and the temperature sensor is arranged on the internal wall of the spray pipe; and an isolation layer in the spray pipe is connected with a circulating water system or a vacuumizing system. According to the method and the self-propelled impulse type thermal fogger, the flue gas temperature of the spray pipe can be controlled in real time according to different requirements of various pesticides on temperature, the requirements of various different pesticides on temperature are met, and thus the applicable range of the thermal fogger is widened.

Description

technical field [0001] The invention relates to a method for controlling the flue gas temperature of a spray pipe of a hot fog machine and a self-propelled pulse hot fog machine using the method. Background technique [0002] The pulse hot fog machine is a commonly used machine for spraying pesticides. Its principle is to use the high-temperature exhaust gas of the gas engine to generate the Venturi effect when it flows at high speed in the exhaust pipe, so that the pesticide liquid is sucked out of the liquid container, and the smoke and The pesticide liquid is mixed and sprayed after atomizing the liquid; considering the need to improve human safety, reduce labor intensity, and improve efficiency, the hot fog machine is placed on the driving part of the chassis that can be driven, and A remote control system is set up to form a self-propelled hot fog machine. [0003] Since the exhaust gas after engine fuel combustion is high temperature, and the performance of many pesti...
