Abstract
The invention provides a material combustion smoke toxicity experiment device. The device is provided with a quartz glass tube, and an experimental material which is cut into a strip shape can be placed into the quartz glass tube. An annular electric heater the temperature of which is controlled by a computer is encircled on the quartz glass tube and is driven by a motor to move at constant speed to carry out sectional heating, and the experimental material is heated to burn to generate smoke. Fresh compressed air enters from one end of the air inlet of the quartz glass tube, and toxic gas with the smoke is delivered into an airtight animal experiment bin in which a tested animal is placed through connecting the air inlet with the air outlet of the quartz glass tube. A detection recording device controlled by the computer controls, detects and records the parameters of temperature, humidity, oxygen density, ambient pressure and the like in the animal experiment bin at any time and detects and records the parameters of behavioral expression physiology and pathology and the like in the experiment process of the tested animal, and the four walls of the animal experiment bin are provided with gas sampling connectors. Waste gas after the experiment is ended is delivered into the smoke absorption treatment device through the air outlet of the animal experiment bin to carry out post-treatment harmless emission. The invention has the advantages that the device can accurately simulate the environments of the toxic smoke generated by various materials in combustion, automatically controls and records the experiment data of all process and provides scientific basis and equipment for correlative study.
Description
Technical field
The present invention relates to a kind of material combustion smoke toxicity experiment device.
Background technology
Military, anti-probably, many materials can burn in the field such as safety evaluation, material development production, fire-fighting, environmental health, construction and decoration, must have a method and apparatus to measure out but whether the gas that burning produces has the weight rank of toxicity and toxicity.For example in the time of breaking out of fire, most of injures and deaths cause because of toxicity on inhalation gas.The method and apparatus of past neither one scientific and precise carries out the test of qualitative, quantitative, the degree that also just cannot Knowing material at combustion-type, whether the mankind is likely damaged and injured.Along with the safety of people to living environment and the progressively attention of environmental protection, select safety more and more paid close attention to and pay attention to without the problem of secondary murder by poisoning material, many relevant laws and regulations have proposed clear and definite requirement.Study a kind of material combustion smoke toxicity experiment device very necessary for this reason.
Summary of the invention
To achieve these goals, technical scheme of the present invention be to provide a kind of this material combustion smoke toxicity experiment device can be widely used in military affairs, anti-probably, the field such as safety evaluation, material development production, fire-fighting, environmental health, construction and decoration.This device has the interior test material (12) that is cut into strip of placing of the sealing quartz glass tube (5) of a two ends ventilation.One can be looped around the upper heating of quartz glass tube (5) by the annular electro well heater (13) of computing machine (7) control temperature, just in time makes by test material (12) burning generation smog when adjusting temperature.The motor (8) that can be controlled translational speed by computing machine (7) drive ring heater (13) at the uniform velocity mobile heat stage by stage in quartz glass tube (5) by test material (12) time evenly burning continue to produce smog.Send into the poisonous gas with smog in fresh compressed air (9) promotion quartz glass tube (5), all enters in the animal experimental chamber (2) of a good seal from quartz glass tube gas outlet (6) output from this quartz glass tube air intake opening (6) one end.The meiofauna that animal experimental chamber (2) inside is placed with test use sucks the toxicity test of smog.The detection record device (4) that computing machine (7) is controlled controls at any time and detection record animal experimental chamber (2) in the parameter such as temperature, humidity, oxygen concentration, environmental pressure, and the behavior in experimentation shows the parameters such as physiology and pathology and carries out detection record to animal subject.Animal experimental chamber (2) wall has special gas sampling interface (1) to carry out quantitative test for collected specimens.Scientific research personnel judges according to animal test results and every data analysis the smog toxicity rank that this kind of test material (12) produces in combustion process.Animal experimental chamber gas outlet (14) is connected in a smog absorption treating device (10) carries out the waste gas of discharge to be discharged in atmosphere after adsorption treatment again.
Effect of the present invention is to provide a kind of material combustion smoke toxicity experiment device, and whether the smog gas that can realize the generation of science mensuration material combustion has the weight rank of toxicity and toxicity.Understand the degree whether this kind of material likely damages and injure the mankind in the time of burning.Solve at military, anti-technical barrier probably, in the field such as safety evaluation, material development production, fire-fighting, environmental health, construction and decoration aspect material combustion smoke toxicity experiment.
