Description

Electric shed curtain type welding fume dust removing room

Technical Field

The utility model relates to a weld cigarette treatment facility field, indicate especially that electronic canopy curtain formula welds cigarette dust removal room.

Background

Welding is a process method which utilizes electric energy to heat, so as to promote the welded metal to locally reach a liquid state or a liquid state, and the welded metal is combined to form a firm non-detachable joint. It is a very common mechanical process in factories. Various pollution types and great harm are generated in the welding process, various occupational diseases (such as silicosis, manganese poisoning, electro-optic ophthalmia and the like) can be caused, and the welding process becomes a large environmental pollution.

Welding fume is the main pollutant and is formed by oxidizing and condensing the vapor generated by metal and non-metal substances under the condition of overheat. The welding fume has the following characteristics:

① small particle of welding fume

The smoke dust is in the shape of flakes, the particle size is mostly less than 1 μm, and the particles are submicron particles.

② the welding fume has high viscosity

The smoke generated during the welding of aluminum alloy is particularly serious in viscosity.

③ the welding fume has higher temperature in the exhaust duct and filter element, and the air temperature is about 50 deg.C.

④ the welding process has a large dust amount

The harmfulness of the welding fume is mainly reflected in the following two aspects: first, since the smoke dust during welding is composed of submicron-sized particles, which are breathable by human beings, can enter the blood through the alveoli together with oxygen, and enter various parts of the human body through the flow of the blood and are deposited, so that pneumoconiosis, manganese poisoning, cancer, etc. are formed, which pose a great hazard to the health of human beings. Welding materials and welded materials with different compositions generate welding smoke with different compositions when welding. The fumes generated from the various welding applications vary, and are determined by the metal base, flux, filler, and the degree and depth of the weld. Secondly, welding fumes are very harmful to the equipment and the surrounding environment. The fumes produced during the welding process are almost metallic dust, which is very prone to flying around the shop. When the air enters the next night, due to the change of the air temperature, the dust is easy to fly and fall on the equipment or enter the equipment through the heat dissipation holes of the equipment. After a long time, the dust is accumulated on the electronic components and circuit boards of the equipment, thereby causing the electronic components and circuit boards of the equipment to break down and short-circuit.

Therefore, when welding, the welding fume is required to be purified by the welding fume processor, and various welding fume processors existing at present are purified, because the temperature of the welding fume is higher, and a large amount of high temperature and even fume particles with sparks are carried in the welding fume, and the fume particles can cause damage to fans, inner walls of pipelines and the like in the welding fume purification equipment and even cause the equipment to be on fire, so that great potential safety hazards exist.
