Description

A kind of welding fume diverting absorption purifier and its absorption and purification method

Technical field

The invention relates to the technical field of air pollution prevention and control, specifically a welding fume diverting absorption purifier and an absorption and purification method thereof.

Background technique

Welding, cutting, polishing, grinding and other construction processes are important processes in construction, mechanical processing and other industries. Metal or non-metal welding materials generate steam during the high-temperature and high-heat welding process, which is oxidized and condensed to form a large amount of welding dust and smoke. (Such as nitrogen oxides, odorous nitrogen, carbon monoxide, dust particles, etc.) These smoke and dust are suspended in the air and accumulate rapidly, which not only pollutes the atmospheric environment, but also harms human health. After the human body inhales it, it can cause dizziness, brain swelling, Skin allergies, asthma, coughing, chest tightness and shortness of breath can lead to respiratory infections and damage to the digestive system in severe cases. Therefore, it is very necessary for the environment and human health to absorb and purify welding fumes before discharging them. At present, there are two main methods for purifying welding fumes: one is dry purification by filtering and adsorbing particles and dust, and the other is wet purification that absorbs welding fume through absorbing liquid or spraying. The dry purification method requires frequent replacement or cleaning of the filter material to prevent the continuous deposition of particles and clogging. However, in some production situations, the treatment effect of the welding fume purifier may be affected due to neglect of maintenance and management; the existing wet purification method of welding fume and The short contact time of the purification liquid, the lack of auxiliary adsorption materials, and the single interaction method with the purification liquid also affect the absorption and purification effect of welding fume.

Due to different welding objects and materials, the amount of welding smoke produced in different scenes is different. The smoke in some scenes is larger, and in some scenes the smoke is smaller, sometimes larger and sometimes smaller. However, most of the existing welding smoke purifiers The air suction volume is fixed, and it is impossible to adjust the motor speed to change the suction power according to the different concentrations of welding smoke in different welding scenes. Either the fan works at full load, or multiple fans are used to achieve the smoking effect, which not only causes a waste of electric energy but also affects the service life of the fan. , the absorption and purification efficiency of welding smoke is not ideal. A large amount of welding smoke escapes into the air because it is not effectively absorbed and purified, causing air pollution and affecting human health.

An absorption and purification method of a welding fume diverting absorption purifier, the steps of which are:

Step 1. Before purifying welding fume, replenish the purification liquid inside the purification chamber through the liquid limiting valve, or replace the purification liquid with the drain valve to ensure that the purification liquid has sufficient purification ability;

Step 2. Push the welding fume diverting and absorbing purifier close to the welding station, turn on the power, and press the high-speed mode button on the control panel. The worm gear fan of the welding fume diverting and absorbing purifier starts to run at a high speed, allowing it to run dry for 1 Minutes or so, the welding smoke diverted absorption purifier is the welding smoke diverted absorption purifier required in claims 1 to 6;

Step 3. After step 1 and step 2 are completed, pull the bellows to adjust the position of the smoke hood so that the smoke hood is close to the welding point. Press the low mode button, mid-range mode button, and high mode button on the control panel according to the welding smoke condition of the welding scene.

There is no obstruction on the purification liquid level between the lower right end of the inclined panel and the right inner wall of the purification chamber, and the gas can From then on, the purification liquid level rises.

(2) In the welding smoke diverting and absorbing purifier of the present invention, an air flow balancing plate is provided at the front end of the connection between the first fan outlet duct and the second fan outlet duct, which can make the welding smoke in the air flow evenly distributed. The mechanism absorbs the welding smoke through the worm gear fan and splits it into two streams from the first fan outlet duct and the second fan outlet duct to the purification mechanism. One stream directly enters the liquefied liquid, and the other directly enters the triangular space and enters the purified liquid. The welding fume is initially purified, and then the gas floats up inside the purification liquid and drives the purification liquid to form water mist to rise: part of the rising gas rises directly from the liquid level at the right end of the purification chamber, and the other part of the rising gas is blocked by the upper inclined panel at the left end of the purification chamber, and is The triangular space formed by the inclined plate and the purification liquid merges with another stream of welding smoke and continues to accumulate. Due to the effect of inertial collision, the moving gas collides with the inclined plate and is rebounded into the interior of the purification liquid again, moving faster and with greater mass. The welding fume particles are separated from the airflow and captured by the rising water mist. The purification is repeated until the gas rises from the unobstructed liquid level of the purification liquid at the right end of the purification chamber. Compared with directly entering the purification liquid without splitting, the welding smoke enters the purification chamber separately after being diverted. The internal purification liquid and triangular space can further improve the absorption and purification effect.

The stirring blade is covered by the screen box to prevent the lumpy loofah from interfering with the stirring blade. When the welding smoke leaves the outlet duct of the first fan and reaches the purification liquid, it is Under the action of the tapered structure of the air outlet of the air outlet, the impact force of the welding fume flow is increased. The purification liquid is impacted and disturbed by the powerful welding fume air flow to generate small bubbles, which enter the triangular space from the second fan outlet duct. The welding smoke is partially absorbed by the water mist, and the welding smoke entering the purification liquid is adsorbed by the massive loofah. At the same time, the massive loofah in the purification liquid is continuously absorbed by the first fan outlet duct and the second fan outlet duct. The two incoming welding fume gas flows disturb and hit the inclined panel and the wall of the clean room. The welding fume adsorbed on the block loofah is washed into the purification liquid. The adsorption capacity of the block loofah is restored, and there is no need to replace the block frequently. Loofah can greatly improve the absorption and purification efficiency of butt welding smoke while reducing the complexity of use.

(4) A welding smoke diverting absorption purifier of the present invention has a filter installed at the top of the purification chamber. The gas purified by the purification liquid rises and is further purified by the filter. The double purification ensures the purification effect of the welding smoke and can effectively solve the problem. The problem of welding smoke pollution.

(5) A welding fume shunt absorption purifier of the present invention has three gear modes: low mode, mid-range mode, and high-end mode. By freely switching between these three modes, the suction volume of the turbine fan is changed to change the suction force. , different gears can be selected according to the amount of welding smoke generated in different welding scenes. Select the high-end mode in scenes with large welding smoke amount, and select the low-end mode in scenes with small welding smoke amount to extend the service life of the fan.

(6) With the welding fume diverting and absorbing purifier of the present invention, the working status of the purification room and the color and transparency of the purification liquid can be viewed through the transparent observation window, which is beneficial to the welding workers in adjusting operations in a timely manner, and facilitates the management and supervision of managers. Department supervision.
