Throttling type gas-liquid exchange device

Abstract

The invention relates to a throttling type gas-liquid exchange device. The throttling type gas-liquid exchange device comprises a main box, a water feeding and draining opening, a negative-pressure water tank and the like. By effects of the negative-pressure water tank, the air pressure of the inside of the main box is the same as that of the inside of the negative-pressure water tank, the negative-pressure water tank does not communicate with the atmosphere, thus, the water level in the main box is stable, and it can be ensured that the throttling type gas-liquid exchange device is not affected by atmospheric pressure during running, and can run stably. Meanwhile, the device is further provided with a water feeding and draining component and a spraying and cleaning system; the use amountof equipment is small; deposited dust can be prevented from corroding the equipment; and the whole equipment is advanced.

Description

technical field [0001] The invention relates to a gas-liquid exchange device, belonging to the technical field of gas-liquid exchange. Background technique [0002] Wet dedusting equipment generally uses water as the purification medium. The particulate pollutants in the waste gas can be effectively removed through the same equipment to capture the particulate pollutants. The removal efficiency is high. The treatment process generally produces a certain amount of sewage, but as the sewage With the development of treatment technology, the sewage generated by wet dedusting equipment can be effectively resolved, and the weight of advantages and disadvantages of wet dedusting equipment has changed. Wet dedusting systems are generally more compact than dry dedusting systems, occupy less land, and have lower initial investment. High efficiency, can be processed nearby. However, most wet dust removal systems have the following problems: 1. Under the action of the induced draft fan...

AI Technical Summary

Problems solved by technology

However, most wet dust removal systems have the following problems: 1. Under the action of the induced draft fan, the wet dust removal equipment is in a negative pressure state inside the equipment. Under the action of atmospheric pressure, the water inside the equipment cannot be removed from The overflow port flows out naturally, and the particulate dust cannot be carried out with the overflow water. The water in the equipment cannot overflow normally, and the water volume is unstable, which will also cause unstable operation of the equipment.

2. The water consumption of general wet dedusting equipment is large, which wastes water resources and increases the load of sewage treatment system at the same time

However, this device does not solve the problem that when the equipment is under negative pressure under the action of the induced draft fan at the air outlet, the water in the equipment cannot overflow normally, and the equipment cannot operate stably.

When those skilled in the art need to adjust the water level at the overflow port, it is easy to think of using the overflow regulating plate to adjust the water level. When the pressure on both sides of the overflow port is different, such as one side is normal pressure and one side is negative pressure, A simple overflow regulating plate cannot meet the requirements of adjusting the water level. Under the action of the pressure difference, the corresponding position of the regulating plate will correspond to the height of multiple water levels. The two sides of the orifice cannot meet the water level requirements of the gas-liquid exchange device

The device also does not address the issue of equipment water consumption
