Embodiment 1

[0023] A forest fire intensity simulator, as attached figure 1 , consisting of a reaction chamber 1 with an unclosed bottom, a heating unit, a smoke collection unit 2 and a temperature sensor 4, the heating unit is arranged in the reaction chamber 1, the smoke collection unit 2 is arranged outside the reaction chamber 1, and is connected to the reaction chamber 1 through a pipeline . In this embodiment, the heating unit is an electric heating wire 31 arranged in the middle of the reaction chamber 1. The electric heating wire is formed by connecting U-shaped electric heating wires sequentially. The temperature sensor 4 is composed of a temperature probe, a lead wire, and a temperature display. And placed in different depths of soil for measuring soil temperature.

[0024] Simulator use method and working principle: when the simulator in this embodiment is working, dig a groove suitable for the bottom edge of the reactor on the soil surface of the field research area or the ind...

Embodiment 2

[0026] A forest fire intensity simulator, as attached figure 2 , including the body, which is composed of a reaction chamber 1 with an unclosed bottom, a heating unit, a smoke collection unit 2 and a temperature sensor 4. The temperature sensor 4 is composed of a temperature probe, a lead wire, and a temperature display. There are several temperature probes placed in different depths of soil used to measure soil temperature. The heating unit is arranged in the reaction chamber 1 , and the smoke collecting unit 2 is arranged outside the reaction chamber 1 and connected to the reaction chamber 1 through pipelines. In this embodiment, the heating unit is composed of a combustion nozzle 32 and an input pipe 33 connected thereto. The combustion nozzle 32 is evenly arranged on the top of the reaction chamber. 2 is provided with a water bath spray head 34 for settling and absorbing the fumes generated in the reaction chamber 1.

[0027] When in use, dig a groove matching the botto...

Abstract

A forest fire intensity simulator, comprising a simulator body consisting of a reaction chamber (1), a heating unit, a smoke collecting unit (2), and a temperature sensor (4). The heating unit is arranged inside the reaction chamber (1). The temperature sensor (4) comprises temperature probes, a lead, and a temperature indicator. The smoke collecting unit (2) is arranged outside the reaction chamber (1) and is connected to the reaction chamber (1) by a pipe. The simulator reduces the costs of a forest fire simulation experiment, avoids air pollution caused by the smoke generated by a forest fire burning experiment, can more safely and precisely obtain data of heated soil, and facilitates the prevention and control of soil erosion as well as the vegetation restoration in burned areas after forest fires.

Description

technical field [0001] The invention relates to a simulation device for forest fire secondary disaster research, in particular to a forest fire intensity simulator and a use method thereof. Background technique [0002] About 4% of the world's forest area suffers disaster loss every year, and forest fire damage to forest resources accounts for nearly 1 / 3 of the lost forest resources. At present, forest fires occur frequently all over the world. There are more than 220,000 fires every year, and more than 6.4 million hectares of forests are burned. 2 , accounting for more than 0.23% of the world's forest coverage. my country is a Shaolin country, with a national forest coverage rate of only 20.36%. At the same time, it is a country with frequent forest fires, with an average annual forest fire occurrence of 16,000 times, and an average annual fire area of ​​9×10 5 hm 2 . [0003] The impact of fire on forest ecosystems is complex, ranging from the reduction of biomass in t...
