Description

Outdoor movable pipe type oil fume purification equipment

technical field

The utility model relates to an oil fume purification device, which is particularly suitable for the oil fume purification equipment for outdoor barbecue operations. the

Background technique

In recent years, outdoor oily fumes, especially those produced by outdoor barbecues, have become unbearable for nearby residents, and the social problem that it is difficult for relevant departments to carry out effective supervision has become more and more prominent. At the same time, for those who sell barbecue, long-term inhalation of barbecue fume will also cause great harm to the human body, because after the fume is inhaled by the human body, it will damage the mucous membrane of the respiratory tract and reduce the immune function of the human body. Oil fume irritates people's eyes and induces cardiovascular disease. Relevant data show that among the factors causing lung cancer, cooking fume is the risk factor second only to "deep smoking" smoke reaching the deep part of the respiratory tract. If the hazards of smoking and cooking fume are eliminated, lung cancer can be reduced by 85%.

There are three main methods of purifying outdoor lampblack:

1. Electrostatic method: It mainly adopts the method of imparting electric charges to oil fume particles, and through the adsorption of opposite charge plates to achieve the effect of dust and smoke removal. The disadvantages are large power consumption, high equipment cost, and difficult cleaning;

2. Solution absorption method: it mainly uses alkaline or washing liquid to absorb oil fume to achieve the purpose of removing it. The disadvantage is that waste liquid will be generated, resulting in secondary pollution;

3. Filtration method: It mainly adopts multi-stage steel mesh filtration, and uses oil fume to hit the steel mesh and stay on the surface of the steel mesh to remove oil particles and dust particles, and achieve the purpose of continuous effect by replacing and cleaning the steel mesh;

In addition, the existing outdoor oil fume purification equipment is usually large in volume, usually about 1 cubic meter, and weighs more than 50 kg. It is very difficult to move and carry, and is not suitable for use in the outdoor barbecue industry.

Detailed ways

In order to understand the purpose, technical solutions and beneficial effects of the utility model more clearly, the utility model will be further described below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited to the following examples.

As shown in Figure 1 and Figure 2,

An outdoor movable pipeline type oil fume purification equipment, comprising:

The two ends of the smoke inlet pipe 1 are smoke inlets 2, and a rectangular windshield 9 is arranged at the smoke inlet 2. The angle of the rectangular windshield 9 can be flexibly adjusted according to needs, so as to better suck the oil fume into the smoke inside pipe 1;

The smoke outlet pipe 3 is connected and communicated with the middle part of the smoke inlet pipe 1, a waste oil outlet is arranged in the middle part of the smoke outlet pipe 3, and a waste oil collection cup 10 is arranged directly below the waste oil outlet, and the waste oil collection cup 10 can It is clamped on the smoke outlet pipe 3, and after collecting a certain amount of waste oil, it can be easily removed for cleaning, and can also be installed quickly;

The first-stage filter plate 4 with holes is obliquely installed in the smoke inlet pipe 1 and separates the smoke inlet pipe 1 from the smoke outlet pipe 3, and the aperture _d1 of the filter plate is 3 mm to 5 mm;

The second-stage conical filter screen 5 is fixedly installed in the smoke outlet pipe 3 in an inclined and fixed manner. The aperture _d2 of the filter screen is 1 mm to 2 mm, and its mesh number is 6 to 10 mesh;

Tertiary fiber filter screen 6 is installed at the smoke outlet 7 of the smoke outlet pipe 3; the three-stage fiber filter screen 6 can be activated carbon fiber, felt, polypropylene, polyethylene and other materials, and its thickness is 6-10mm , can withstand high temperature of 50-100 ℃, and its mesh number is 100-200 mesh;

And, in the smoke outlet duct 3, between the third-stage fiber filter screen 6 and the second-stage conical filter screen 5, an axial flow fan 8 made of metal is set, and the wind speed of the axial flow fan 8 is the highest. The best is 10-18m/s.

Further, a plurality of support rods 11 are arranged below the smoke inlet pipe 1, and a pulley 12 is connected to the lower ends of these support rods 11. The support rods 11 can be arranged in multiple sections, and each section can move relative to each other to The height of the entire support rod 11 can be adjusted flexibly, so that it can be adapted to barbecue operating platforms of different heights, and the position can also be adjusted flexibly, and it is also convenient to carry without affecting the line of sight.
