[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The utility model provides a building material monomer combustion test device. Through combustion, water in the water tank evaporates to generate steam. The steam is blown from the air outlet pipe to the ventilation component and mixed with the smoke generated by the combustion. The water in the steam absorbs the solid particles in the smoke and makes the solid particles fall. This reduces the pollution of the smoke to the atmosphere and realizes the recovery and utilization of heat. Please refer to Figure 1-Figure 6 , including: a combustion chamber 100, a ventilation component 200 and a water tank 300.

[0033] The combustion chamber 100 includes a chamber body 110, an air vent 120 and a flame device 130. The air vent 120 is provided at the top of the chamber body 110, and the flame device 130 is provided at the rear side of the inner cavity of the chamber body 110.

[0034] The building materials are placed inside the house body 110 , and flames are sprayed out by the flame device 130 to ignite the building materials, and smoke generated by the combustion floats up and is discharged from the vent hole 120 .

[0035] The ventilation assembly 200 is connected to the ventilation hole 120, and the ventilation assembly 200 uses a pipe to guide the smoke.

[0036] The water tank 300 is arranged at the top of the inner cavity of the housing 110. The water tank 300 comprises a housing 310, a water inlet pipe 320 and an air outlet pipe 330. The side of the housing 310 is provided with a water inlet pipe 320 extending out of the housing 110. The side wall of the housing 310 is provided with an air outlet pipe 330 facing the air inlet end of the ventilation assembly 200.

[0037] Among them, the box body 310 adopts a metal shell, and water is added to the water tank 300 through the water inlet pipe 320. When the flamer 130 sprays flames and the building materials burn, the water tank 300 will be heated, so that the internal water evaporates into steam, and the steam blows from the exhaust pipe 330 to the ventilation component 200, so that the moisture is mixed with the smoke and absorbs the particles in the smoke.

[0038] The ventilation assembly 200 includes a ventilation pipe 210 and an impeller 220. The ventilation pipe 210 is connected to the ventilation hole 120, and the impeller 220 is arranged at the air inlet end of the ventilation pipe 210.

[0039] The outlet pipe 330 is a thin tube, which can increase the outlet pressure of the steam. The steam blows toward the impeller 220, driving the impeller 220 to rotate, and the impeller 220 further drives the smoke to be discharged.

[0040] Specifically, the impeller 220 includes a bracket 221, a rotating shaft 222 and blades 223. The bracket 221 is fixed to the air inlet end of the vent pipe 210. The rotating shaft 222 is arranged on the bracket 221, and the blades 223 are arranged outside the rotating shaft 222.

[0041] The steam blows toward the blades 223, causing the impeller 220 to rotate, and the rotating blades 223 draw air, causing the smoke to be discharged upward.

[0042] Solid particles will be adsorbed by steam, but only larger particles will sink, while smaller particles will be discharged with smoke and steam. To further improve the purification effect, a filter box 230 is provided on the ventilation pipe 210, and a filter element 240 is inserted into the side wall of the filter box 230;

[0043] The smoke is further filtered and purified by the filter element 240, and after use, the filter element 240 can be pulled out for cleaning and replacement.

[0044] Since the fire of building materials needs to be extinguished after burning to prevent the residue from re-igniting, a nozzle 340 is provided at the bottom of the box 310;

[0045] After combustion, the water in the box 310 is sprayed out through the nozzle 340 and poured on the burned building materials to prevent re-ignition. At the same time, the water in the box 310 can be further utilized.

[0046] Since the burning of building materials requires contact with air, if they are placed directly at the bottom of the inner cavity of the housing 110, the bottom contact position is not easy to circulate air. Therefore, a bracket 140 is provided at the bottom of the inner cavity of the housing 110, and the bracket 140 is provided with evenly distributed air grooves 141;

[0047] The building materials are placed on the bracket 140 and air flow is exchanged through the air groove 141 to facilitate the combustion of the building materials.

[0048] Since the combustion chamber will generate high temperature, in order to avoid the working environment temperature rising and affecting the staff's test, the room body 110 adopts a double-layer structure, and an insulation layer 150 is provided in the interlayer to isolate the heat in the room body 110 and avoid the external temperature of the room body 110 from rising.

[0049] To facilitate installation of the box 310 , a mounting plate 350 is provided on the top side of the box 310 . The mounting plate 350 is provided with mounting holes 360 . Bolts are passed through the mounting holes 360 to mount the box 310 on the top of the inner cavity of the room 110 .

[0050] During specific use, the building materials are placed on the bracket 140, the flame device 130 sprays flames to ignite the building materials, and the smoke generated by the combustion floats up and is discharged from the vent 120. When the flame device 130 sprays flames and the building materials burn, the water tank 300 will be heated, causing the internal water to evaporate into steam, and the steam will blow from the outlet pipe 330 to the ventilation component 200, and the steam will blow to the impeller 220, driving the impeller 220 to rotate, and the impeller 220 will further drive the smoke to be discharged, causing the water to mix with the smoke, absorbing particles in the smoke, and further filtering and purifying the smoke through the filter element 240. After use, the filter element 240 can be pulled out for cleaning and replacement. After combustion, the water in the box 310 is sprayed out through the nozzle 340 and poured on the burned building materials to avoid re-ignition. At the same time, the water in the box 310 can be further utilized.

[0051] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
