A packed tower for gas purification

Abstract

The invention relates to the technical field of gas purification, and discloses a packing tower for gas purification, which includes a tower body, an air inlet pipe, a packing layer, a liquid inlet pipe, a water retaining plate, an air outlet pipe, and a sludge pipe, and the air inlet pipe is arranged on the tower body The packing layer is installed inside the tower body, the liquid inlet pipe is arranged inside the tower body, the water baffle is arranged inside the tower body, the gas outlet pipe is connected to the top of the tower body, the water baffle, the liquid inlet pipe , The packing layer is arranged from top to bottom, the sludge pipe is arranged at the bottom of the tower body, and fan-shaped plates are installed inside the air inlet pipe, and the fan-shaped plates are divided into two groups and installed in the tower body. On the one hand, it can cancel the static electricity of solid particles in the exhaust gas, making the purification of the particles more convenient, increasing the safety of the exhaust gas during treatment, and at the same time converting the incoming exhaust gas from low temperature to high temperature, so that the exhaust gas expands when heated, automatically rises up, and accelerates The flow speed of the exhaust gas, at the same time, makes the particles automatically fall down, so that the tower body maintains a better purification state during use.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a packed tower for gas purification. Background technique [0002] The tower packing refers to the tower packing in the packed tower. Its function is to provide a sufficient contact surface for the gas and liquid phases, and to create conditions for improving their turbulence. The main function is to purify the exhaust gas discharged in the chemical industry. [0003] The working principle of the existing packed tower is as follows: Figure 5 As mentioned above, the exhaust gas enters from the inlet pipe 2 and passes into the tower body 1, then the liquid inlet pipe introduces the absorbent and sprays it evenly into the packing layer from the top of the tower and flows downward, and the exhaust gas and the absorbent fully contact in the packing layer , take out the harmful substances and solid particles in the exhaust gas. When the exhaust gas is purified, the solid part...

[0003] The working principle of the existing packed tower is as follows: Figure 5 As mentioned above, the exhaust gas enters from the inlet pipe 2 and passes into the tower body 1, then the liquid inlet pipe introduces the absorbent and sprays it evenly into the packing layer from the top of the tower and flows downward, and the exhaust gas and the absorbent fully contact in the packing layer , take out the harmful substances and solid particles in the exhaust gas. When the exhaust gas is purified, the solid particles contained inside flow upward with the gas, causing the particles to float in the packing layer, blocking the gaps in the packing layer, affecting the rising flow rate of the air flow, and causing the packing to The layer is in a closed state, the gas cannot flow upward again, and the packing layer needs to be disassembled to remove the internal solid particles, resulting in a large amount of filler loss from the packing layer, increasing the loss of the packing layer, and the absorbent flows from top to bottom, The gas rises from the bottom up, and the two resist each other. The upward force of the absorbent eliminates the upward force of the gas, causing all the exhaust gas to accumulate at the bottom of the tower, resulting in excessive pressure at the bottom of the tower, and the external gas cannot be reintroduced into the tower. The inside of the packing layer causes sloshing inside, and the exhaust gas purification is not complete, which further affects the purification of the gas.
