ZR1000 carbon dioxide and traditional fire extinguishing equipment
Performance comparison
1. Gas production principle:
Concentrated sulfuric acid reacts with sodium bicarbonate or ammonium bicarbonate, the chemical reaction formula is:
H2SO4 + 2NH4CO3 → (NH4) 2SO4 + 2H2O + 2CO2 ↑
Produce carbon dioxide gas for fire fighting.
Compared with the advantages of traditional mine fire extinguishing equipment:
Only produces carbon dioxide and other, does not produce oxygen and other combustion-supporting components;
The entire reaction process is endothermic, without high temperature
Second, the comparison of carbon dioxide gas and traditional fire extinguishing equipment:
The mine fire extinguishing medium is mainly nitrogen and carbon dioxide, and the equipment for producing nitrogen is nitrogen generator and fuel oil inert
Gas fire extinguishing device, the comparison is as follows:
Nitrogen generator
Mine nitrogen generators are divided into cryogenic air separation type, membrane separation type, and pressure swing adsorption type.
Cryogenic air separation nitrogen generator is characterized by large gas production and high nitrogen concentration, but it is bulky and is installed on the ground
And cannot be used underground.
Mine-use mobile membrane separation nitrogen production unit and coal mine (ground) pressure swing adsorption (PSA) nitrogen production unit
The nitrogen production machine's gas production volume contains oxygen concentration of 3-5%, and because of the original oxygen volume and
The existence of external air leakage is not easy to reach the "injection of coal mine safety regulations" Article 238, paragraph 2
"The nitrogen concentration is not less than 97%", it is more difficult to reach the "Interpretation of Coal Mine Safety Regulations" by experts.
Interpretation of the provisions on nitrogen injection and fire prevention, the "oxygen concentration in the goaf should not exceed 7%" and nitrogen injection
Fire extinguishment "the oxygen concentration in the fire zone shall not exceed 3%". In addition, nitrogen is lighter than air
The spread of the top of the fire zone, which in turn affects the inerting effect of the fire zone, often fails to achieve the purpose of extinguishing the fire.
Fuel inert gas fire extinguishing device
It is mainly composed of DQ-150, DQ-500 and DQ-1000. The device has large gas production and is suitable for coal mines
Quickly extinguish the fire underground. However, due to insufficient combustion of aviation fuel, the gas produced contains 3-5%
The reaction of oxygen and trace CO is exothermic, and the temperature of inert gas is as high as 70 degrees. Due to the process of gas production
To burn a large amount of aviation fuel, the generated oxygen, CO, high temperature and burning aviation fuel cause the entire production
The gas process is very dangerous.
Performance comparison table
Comparison of fuel gas inert gas fire extinguishing device nitrogen generator carbon dioxide generator
Gas concentration ≤93% ≤95% ≥98%
Whether the reaction produces oxygen produces 3-5% oxygen produces 3-5% oxygen
Does the reaction produce toxic and harmful gases produce CO does not produce
Extinguishing gas temperature ≥70 degrees ≥50 degrees ≤30 degrees
Do you need electricity? Do you need electricity?
The safety of the gas production process requires the burning of aviation kerosene in the mine. The process is dangerous and difficult to control.

Nursing Home bed delivers all the functionality of a Hospital Bed but with a more homely appearance. With electric hi-lo and electric backrest adjustment, it is easily positioned to support the most ergonomically friendly positions.
The range of height combinations will help when getting in and out of bed while also making it easier to assist and transfer the user.
We have an extensive range of Nursing Home Beds that allow for the user to be cared for at home. They are similar in function to those used in hospital, so the beds raise up and drop down and also profile to allow the use to sit up or raise the leg section.
Compared to a traditional Hospital Bed our range of Nursing Beds feature additional safety features and controls such as side rails, hi-lo lifting functions and other additional positioning controls. The clearly marked handset is simple to use for both carers and end users alike.
