What kind of explosion proof fan should be installed in the hazardous chemicals warehouse

The general hazardous chemicals warehouse needs an explosion-proof fan with the explosion-proof mark EXDIIBT4; If you have hydrogen, acetylene, carbon disulfide and other gases, you need to use Exdiic's explosion-proof fans.

From Nanyang Zhongtian explosion-proof.

1. Electrical facilities.

Try not to install other electrical facilities in the warehouse. Open at the bottom of each storeroom wall.

The sash meets the ventilation requirements.

If you want to install electric lights,

Exhaust fans, etc., must be selected.

Defend. Practical Manual of Technical Standards and Specifications for the Design, Installation, Maintenance, Testing and Safety of Explosive Electrical Appliances

For the required explosion-proof products, the power cord should be sealed with a galvanized steel water pipe, and the connection part should be flexed.

Explosion-proof pipe transition, sealed pipe should be grounded.

Explosion-proof switches and sockets should be installed outside the warehouse.

The installation position of the exhaust fan is set at the bottom and top of the warehouse wall.

The vapor density emitted for many hazardous chemicals is greater than that of air, and the combustible vapor will be on the ground.

Attachments accumulate. A machine is set at the bottom to facilitate the extraction of the vapor accumulated on the ground.

Thermometers and air conditioners should be installed in chemical warehouses to control the temperature in chemical warehouses.

Degree. The location of the air conditioner should be far away from the intake and exhaust equipment.

At the same time, it meets the requirements for explosion-proof electrical appliances.

Second, fire protection facilities.

Set up surveillance cameras.

Toxic gas detectors.

Temperature detectors and other monitoring.

Probing system. At the same time, the monitoring and detection system should meet the requirements for explosion-proof electrical appliances. Monitor.

The various parts of the detection system are connected to the fire control room.

Set up dry powder fire extinguisher and hanging dry powder automatic fire extinguishing device.

3. Other hardware facilities.

The door of the warehouse should be set up.

The slope is about 10cm to prevent the packaging from being damaged and flammable.

The liquid flows to the outside and causes a fire when it encounters an ignition source.

Set up explosion-proof doors. Explosion vents should have high blast strength.

Angle steel is required.

Or channel steel, I-beam assembly and welding to make the door frame skeleton.

The door panels are equipped with high blast resistance.

A steel plate or boiler steel plate production.

There should be a drain tank in the chemical warehouse, and the ground should be set up as a slope to prevent leakage.

The liquid is collected into the drain tank. The drain tank should be set with a certain slope, and its end should be set.

There is a pool of liquid.

Both indoors and outdoors.

Facilitates the collection of liquids in the drain tank.

Inside the pool. The liquid collection tank should have a volume of one cubic meter, and its structure should be leak-proof. Liquid collection tank is set up.

Place it in the corner of the wall and set up an outlet on the wall to facilitate the extraction of the leaked chemical liquid.

The collection tank should be sealed as much as possible.

Prevents the collected liquid from volatilizing into the air.

Danger to the environment.

Harm. At the same time, there is a fire hazard.

The hazardous chemicals warehouse must be equipped with protective equipment such as gas masks, chemical gloves, chemical protective shoes, and protective glasses for emergency preparation.

Post warning signs and signs on the physical and chemical properties and disposal of hazardous chemicals.

Install lightning protection facilities according to specifications.
