Technical field

The utility model relates to a kind of security against fire field of tool, in particular to concentration dilution when acetylene is revealed and Automatic alarm and protection when concentration of acetylene is exceeded.

Background technique

The accident of fire happens occasionally caused by revealing in enterprise production process because of acetylene poisoning even acetylene, many operation fields Gas concentration do not accomplish to monitor in time, seriously threaten the health of operating personnel.In order to control acetylene gas to work The influence of industry personnel health and ambient enviroment, it is necessary to the gas in Work places is monitored first, according to the result of monitoring It takes targetedly measure to be administered, gas leakage, explosion can be effectively avoided or even the phenomenon that fire occurs.It is existing at present The capable type for concentration of acetylene detector is more, and measurement accuracy is higher, but function is limited to concentration detection mostly, i.e., in acetylene Gas concentration makes sound-light alarm when occurring exceeded in time, does not take for the exceeded detection result of concentration of acetylene and arranges accordingly It applies, environmental pollution cannot be controlled in time.

Summary of the invention

In view of it is above-mentioned the problems of in the prior art, the purpose of this utility model is a kind of concentration of acetylene of researching and designing Detection alarm and protective device, can in acetylene gas concentration over-standard automatic spray water, achieve the purpose that diluent gas, can be effective The generation for avoiding the accidents such as fire, explosion, poisoning because caused by leaking acetylene gas.

The utility model includes concentration of acetylene detecting module, temperature sensing module, acoustic-optic alarm, automatic spraying device With independent current source module, concentration of acetylene detecting module and temperature sensing wired in parallel；Automatic spraying device is opened with 50%LEL concentration It closes, buzzer series connection；The exceeded LED alarm lamp of concentration of acetylene is connected with 20%LEL switch, simultaneously with buzzer, automatic spraying device Connection, while connecting with concentration of acetylene detector module；Temperature sensing module and 30 DEG C of switches and temperature exceeding standard LED alarm lamp phase Even；Acoustic-optic alarm is made of the exceeded LED alarm lamp of concentration of acetylene, temperature exceeding standard LED alarm lamp and buzzer；Described is only Vertical power module provides electric energy for concentration of acetylene detecting module and temperature sensing module；Concentration of acetylene detecting module completes acetylene not With the detection of concentration, and according to the opening and closing of surveyed concentration of acetylene control 20%LEL density switch, 50%LEL density switch；It is described Acoustic-optic alarm can complete visual alarm when concentration of acetylene is more than 20%LEL, it is complete when concentration of acetylene is more than 50%LEL It alarms at sound sensation, and completes visual alarm when temperature is more than 30 DEG C；The automatic spraying device is more than in concentration of acetylene Automatic spray water when 50%LEL.

After adopting the above structure, can be realized concentration of acetylene it is exceeded when vision and audio alarm, temperature exceeding standard when view Feel automatic spray when alarm and acetylene gas leak to 50%LEL or more, the functions such as diluent gas concentration, by whole Body cooperation has achieved the purpose that alarm and protection.

The utility model has the advantages that it will be apparent that being mainly manifested in:

1, integration degree is high for the utility model, saves space.

2, the utility model warning device is perfect, be divided into temperature exceeding standard alarm, concentration of acetylene it is low exceeded when visual alarm, Audible alarm when concentration of acetylene is high exceeded；In addition, the substance in used automatic spraying device can be water, reach acetylene Chemical reaction generation innocuous substance occurs for gas and water when concentration severely exceeds can effectively keep away to reach diluted purpose Exempt from acetylene gas concentration to continue to rise the generation for causing the accidents such as fire explosion.

Detailed description of the invention

Attached drawing is the circuit diagram of the utility model.

Description of symbols: 1, concentration of acetylene detecting module, 2, temperature sensing module, 3, automatic spraying device, 4, independence Power module, 5,50%LEL density switch, 6, buzzer, 7, the exceeded LED alarm lamp of concentration of acetylene, 8,20%LEL switch, 9, 30 DEG C of switches, 10, temperature exceeding standard LED alarm lamp.

Specific embodiment

Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.

As shown in the picture, in a kind of concentration of acetylene detection alarm and detection device, including concentration of acetylene detecting module 1, Temperature sensing module 2, acoustic-optic alarm, automatic spraying device 3 and independent current source module 4, concentration of acetylene detecting module and temperature It is in parallel to spend detecting module；Automatic spraying device is connected with 50%LEL density switch 5, buzzer 6；The exceeded LED alarm of concentration of acetylene Lamp 7 is connected with 20%LEL switch 8, in parallel with buzzer, automatic spraying device, while being connected with concentration of acetylene detector module； Temperature sensing module is connected with 30 DEG C of switches 9 and temperature exceeding standard LED alarm lamp 10；Acoustic-optic alarm is exceeded by concentration of acetylene LED alarm lamp, temperature exceeding standard LED alarm lamp and buzzer composition；The independent current source module is concentration of acetylene detecting module Electric energy is provided with temperature sensing module；Concentration of acetylene detecting module completes the detection of acetylene various concentration, and according to surveyed acetylene The opening and closing of concentration control 20%LEL density switch, 50%LEL density switch；The acoustic-optic alarm can be in concentration of acetylene Visual alarm is completed when more than 20%LEL, sound sensation alarm is completed when concentration of acetylene is more than 50%LEL, and be more than 30 in temperature DEG C when complete visual alarm；Automatic spraying device automatic spray when concentration of acetylene is more than 50%LEL.
