Production process principle of PVC gloves and analysis of pollution sources


For PVC glove baking, the three essential raw materials and additives are stirred and mixed into an emulsion in a fixed proportion. After treatment, the mixture is sent to the dipping tank in the production line with a pump. Under normal production conditions, the The hand mold automatically enters the dipping tank and rotates continuously to make the emulsion on the surface of the hand mold uniform. Then it moves into the oven with the production line. The temperature of the oven is controlled at 230-250 degrees Celsius. Under this condition, the emulsion on the hand is cured and formed. The hand mold coming out of the oven undergoes processes such as natural cooling and lip curling, and the gloves are manually unloaded from the hand mold/automatically demoulded. The removed gloves will be put into storage after inspection

Powder-free PVC gloves process

Ingredients → Stirring → Filtration → Standing defoaming → Sticky material → Dropping → Baking → Cooling → PU water treatment → Baking → Cooling → Lip curling → Demoulding → Quality inspection → Packaging → Storage


In the process of high-temperature production and baking of PVC gloves, 10-15% of the solvent of the mixture volatilizes to form baking flue gas. These organic compounds are heated and volatilized together, and are discharged from the exhaust gas along with the waste hot air. The characteristics of PVC glove exhaust gas are high temperature and high concentration


Treatment process selection

The equipment of this program adopts Kelan water-resistant industrial electrostatic smoke purification equipment, honeycomb plasma equipment, VOC adsorption device, stainless steel multi-faceted tube cooler, and photolysis equipment. The industrial electrostatic fume purification equipment is composed of a cabinet, a main control box, an intelligent digital power supply, a patented water-resistant stainless steel electric field, a porous air baffle, an over-temperature detection circuit and a PLC control circuit


  installed in the main control box

According to the characteristics of the flue gas, our company provides the following treatment solutions: Smoke collection system (smoke hood, pipe) + Condensation system + Electrostatic adsorption purification system + Phase change system +Plasma purification system + VOC adsorption purification system + Deodorization system + Extraction system (End fan, chimney)


1:Induced draft fan  2:fire damper  3:Steam  4:Pretreatment ESP  5:fire damper  6:Pressure relief valve  7:Recovery device  8:Cooling Tower  9:production line





Smoke collecting system:

The fume exhaust gas volatilized from the glove production line is collected by the branch pipe on the oven and collected into a main pipe


Condensation system

The flue gas enters the condenser, through the non-contact heat conduction heat exchange between the chilled water and the high-temperature flue gas, the adsorbed recyclate in the flue gas is condensed, and the pollutants in the flue gas are condensed and aggregated into large oil fume particles


Electrostatic adsorption system

The purification equipment uses the electrons emitted by the cathode in the high-voltage electric field and the negative ions generated by the electrons colliding with air molecules to capture and charge the oil fume particles, and use the electric field to make the charged oil fume particles adsorbed by the anode and flow to the oil hopper at the bottom of the equipment and drain through the oil drain


VOC adsorption

The modified molecular sieve adsorbs the organic solvents in the exhaust gas of PVC gloves, and desorbs and recycles them, which can greatly reduce the VOCS concentration in the exhaust gas and recover a large amount of valuable high-purity recyclates to achieve material balance


Plasma purification system

The flue gas after cooling and modification enters the plasma purification equipment, and uses the effects of high-energy electrons, free particles and pollutants in the exhaust gas to decompose pollutant molecules in a short time, and various reactions occur to degrade pollutants


UV light deodorizes

The flue gas enters the light deodorization equipment, and the high-energy ultraviolet light beam and ozone are used to synergistically decompose and oxidize the flue gas, so that the industrial flue gas substances are degraded and converted into low-molecular compounds, water and carbon dioxide


Extraction system

The purified flue gas is directly discharged through the chimney
