Technical Field

[0001] The present application relates to the technical field of aluminum ash testing equipment, and in particular to a hazardous environment testing chamber for aluminum ash. Background Art

[0002] The traditional disposal methods are basically landfill or open-air dumping. Such disposal measures not only occupy a large amount of land, but the soluble salts and ammonia produced by the reaction will be transferred through wind, sun, and rain, or evaporate into the atmosphere, or mix into rivers with rainwater, and seep into the ground to pollute the soil and groundwater, causing great harm to the growth of animals and plants and the human body, destroying the ecological environment, and affecting the ecological balance.

[0003] The environmental hazards of aluminum ash in related technologies are mainly reflected in the following three points: ① The fluoride leaching toxicity in secondary aluminum ash exceeds the standard of "Hazardous Waste Identification Standard Leaching Toxicity Identification", and is highly corrosive, and some of it will exceed the standard of "Hazardous Waste Identification Standard Corrosive Identification". Direct storage will lead to an increase in the pH value of surrounding groundwater and soil, and cause fluorine pollution; ② Secondary aluminum ash contains aluminum nitride, metallic aluminum, aluminum carbide, etc., which will release a large amount of ammonia when in contact with water, and produce hydrogen, methane, and other flammable and explosive gases, polluting the atmospheric environment, posing a safety hazard; ③ Secondary aluminum ash contains a large amount of soluble salts, and dissolved, seeped, and accumulated will lead to soil salinization and water pollution.

[0004] In view of the above-mentioned related technologies, the inventor believes that: the current understanding of the harm caused by aluminum ash is very clear, but there is no environmental test chamber designed to quantitatively analyze the natural volatilization of aluminum ash, the salinization of soil caused by aluminum ash, and the dissolution of harmful substances in aluminum ash by rainwater. Therefore, it is impossible to quantitatively determine the harm of aluminum ash in its natural state. Utility Model Content

[0014] Furthermore, a control panel is provided on the outside of the test chamber body, and the control panel cooperates with the combustible gas detector and the exhaust fan respectively.

[0015] Furthermore, a drainage hole is provided at the bottom of the test chamber body.

[0021] The following is combined with Figure 1-2 This application is described in further detail.

[0022] The present application embodiment discloses a hazardous environment test chamber for aluminum ash, referring to Figure 1 and Figure 2 In this embodiment, the test chamber includes a test chamber body 1, an aluminum ash placement platform and a spray assembly. The aluminum ash placement platform is placed at the bottom of the test chamber body 1, and is used to place aluminum ash.

[0023] Specifically, refer to Figure 2 In this embodiment, the aluminum ash placement platform includes a seepage collection base 2, a fence 3, and a placement orifice plate 4. The seepage collection base 2 is placed at the bottom end of the interior of the test chamber body 1; the fence 3 is fixedly installed on the top of the four sides of the seepage collection base 2; the placement orifice plate 4 is installed on the top of the seepage collection base 2, and a placement cavity is formed between the placement orifice plate 4 and the fence 3, and the placement cavity is used to place the aluminum ash, so as to facilitate the subsequent testing experiment of the aluminum ash.

[0024] At the same time, the spray assembly is installed at the top of the interior of the test chamber body 1, and the spray assembly can spray water inside the test chamber body 1 to spray the aluminum ash placed on the aluminum ash placement platform.

[0025] Specifically, refer to Figure 2 In this embodiment, the spray assembly includes a spray pipe 5, a spray head 6 and a water supply device. There are a plurality of spray pipes 5, which are installed at the top of the interior of the test cabin body 1; there are a plurality of spray heads 6, which are evenly installed on the spray pipes 5, and the spray heads 6 are in a rectangular array structure, so as to be located at the top of the interior of the test cabin body 1; the water supply device is arranged outside the test cabin body 1, and the water outlet of the water supply device is connected to the spray pipes 5.

[0026] When the water supply equipment is started, the water supply equipment discharges water into the spray pipes 5, and then the water is discharged into the spray head 6 along the spray pipes 5, and finally the water is evenly sprayed on the aluminum ash in the placement cavity along the spray heads 6, so as to simulate the influence of rainwater on the aluminum ash by spraying water, and the aluminum ash after spraying is placed on the top of the placement orifice plate 4 for a long time, and the seepage is collected to the seepage collection base 2 through the placement orifice plate 4, so as to realize the quantitative test of the dissolution of harmful substances in aluminum ash of a quantitative volume under the condition of determined rainfall.

[0027] Similarly, soil is first placed in the placement cavity formed by the orifice plate 4 and the fence 3, and then aluminum ash is placed, and then spraying is performed, so as to achieve the degree of salinization of the soil by the leakage of a certain volume of aluminum ash under a determined rainfall.

[0028] Preferably, a drainage hole 7 is further provided at the bottom of the test chamber body 1, and the drainage hole 7 is used to discharge the leaked liquid to the outside of the test chamber body 1, so as to facilitate the unified collection and treatment of the leaked liquid.

[0029] In addition, refer to Figure 1 and Figure 2 In order to quantitatively detect ammonia and flammable and explosive gases released by aluminum ash when it is piled in rainwater, in this embodiment, an air sampler 8 is arranged on the outside of one side of the test cabin body 1. The air sampler 8 is firmly installed on the ground through a support frame, and a bubble absorption tube 9 is connected to the absorption end of the air sampler 8; when the air sampler 8 is started, the pipe mouth of the bubble absorption tube 9 generates suction.

[0030] At the same time, a detection hole 10 is opened on one side of the test chamber body 1, and the bubble absorption tube 9 cooperates with the detection hole 10 so that the bubble absorption tube 9 is inserted into the interior of the test chamber body 1 along the detection hole 10. When the air sampler 8 is started, the bubble absorption tube 9 absorbs ammonia and flammable and explosive gases inside the test chamber body 1, thereby effectively testing these ammonia and flammable and explosive gases.

[0031] In addition, refer to Figure 1 In this embodiment, a combustible gas detector 11 is installed on the outside of the test chamber body 1, and the detection end of the combustible gas detector 11 is inserted into the interior of the test chamber body 1 to continuously detect and record the combustible gas concentration inside the test chamber body 1.

[0032] Preferably, an exhaust fan 12 is installed on the top of the test chamber body 1, and a control panel 13 is also installed on the outside of the test chamber body 1. The control panel 13 is respectively connected to the combustible gas detector 11 and the exhaust fan 12 to control the combustible gas detector 11 and the exhaust fan 12.

[0033] When the combustible gas detector 11 detects that the combustible gas concentration reaches a certain dangerous threshold, the control panel 13 controls the exhaust fan 12 to promptly evacuate the combustible gas inside the test chamber body 1, thereby ensuring the safety of the test chamber.

[0034] Therefore, by setting up a structure in which the test chamber main body 1, the aluminum ash placement platform and the spray component cooperate with each other, the aluminum ash can be placed in the aluminum ash placement platform, and then the quantitative test of the dissolution of harmful substances in the aluminum ash by rainwater can be realized through the spray component, thereby not only realizing the salinization test of the soil by aluminum ash landfill and the accumulation test of harmful substances in the soil, but also realizing the test of ammonia and flammable and explosive gases released by aluminum ash under natural rainwater stacking.
