A device and method for treating the emission of molten sulfur dioxide from gasified slag

Abstract

The present invention proposes a device and method for treating sulfur dioxide emissions from molten gasified slag, and relates to the field of sulfur dioxide emission treatment. The blades and the guide ring together form a rotating structure. A guide pipe is fixedly connected to the inner wall of the guide ring, and the guide pipe is fixedly connected to the inner wall of the guide ring in an annular array. The existing problem that the external gas cannot fully contact with the desulfurized liquid due to uneven gas distribution when entering the desulfurization tower is solved, which leads to reduced sulfur dioxide removal efficiency. The rotation of the guide ring is used to automatically adjust the water intake. Compared with traditional vertex gas distribution and the situation where the air intake cannot be adjusted according to the gas flow rate, this design can more fully make the gas and water body fully contact through the linkage between the water intake and the rotation of the guide pipe to distribute the gas, so as to achieve the purpose of improving the purification effect.

When the gasification slag is processed, a corresponding melting furnace is needed to burn the gasification slag. When it is burned, in order to better deal with the sulfur dioxide generated during its combustion, a corresponding desulfurization tower is needed to treat the waste gas generated when the gasification slag is melted. However, when the existing treatment device is in use, it lacks an effective uniform gas distribution structure, so when the external gas enters the interior of the desulfurization tower, it is easy for the uneven distribution of the gas to cause it to fail to fully contact with the desulfurized liquid, which will cause some sulfur dioxide to fail to be fully removed, and there are limitations.

[0003] Therefore, in view of the deficiencies in the actual production and implementation of the above-mentioned scheme, it has been revised and improved.

[0014] The present invention discloses a system method for a gasified slag molten sulfur dioxide emission treatment device, comprising the following steps:

[0015] 1) When the sulfur dioxide generated during the melting of the gasified slag needs to be purified, the exhaust pipe of the external melting furnace can be connected to the air inlet pipe fixedly connected to the outer side of the base body, and after the exhaust pipe and the air inlet pipe are connected, air can be introduced into the guide ring and the inner part of the blades fixedly connected to the tower body and the tower cover;

[0016] 2) Then, when the airflow enters the interior of the blade, the current blade can be pushed quickly synchronously, and when pushing, air can be taken in through the air inlet holes provided on the outer peripheral surface of the guide ring, so that the gas enters the interior of the guide ring and is collected;

[0017] 3) When the gas enters the guide ring, it can simultaneously enter the inner position of the guide pipe fixedly connected to the guide ring, and when the gas enters the guide pipe, it can be discharged through the air holes opened on the outer peripheral surface of the guide pipe. In the process of discharging air, the guide pipe will synchronously rotate with the guide ring and the blades, so that the exhaust gas entering the tower body and the tower cover can generate a certain vortex to move upward and perform atomization operation with the water flow sprayed by the nozzle;

[0018] 4) When the external gas enters the inside of the air intake pipe, when the temperature of the incoming gas is high, the heat will be synchronously conducted to the heat conducting pipe and the heat conducting rod set in the air intake pipe, and when the heat enters the internal position of the gas storage pipe fixedly connected to the outside of the manifold, the gas in the gas storage pipe will expand due to the high temperature, so that it can push the piston and the guide rod upward, and synchronously drive the bottom plate and the baffle to move upward, so that the flux of the water entering the manifold can be increased, and the flow rate of the purification liquid sprayed by the nozzle can be increased synchronously to achieve rapid spraying;

[0019] 5) Under normal conditions, the baffle plate rotatably connected to the inside of the discharge pipe is set vertically to the discharge pipe through a guide shaft. Therefore, when the bottom plate moves upward, the rack fixedly connected to the top surface of the bottom plate can be pushed synchronously, and the baffle plate can be flipped through the meshing transmission of the rack and the gear fixedly connected to the outside of the guide shaft to control the gas flow in the discharge pipe, which can achieve phased obstruction of the gas, so that the gas entering the tower body can be fully purified.

[0020] After adopting the above technical solution, the beneficial effects of the present invention are:

[0021] 1. In the present invention, by providing a guide ring and blades that can rotate along the tower body, when external gas is taken in through the air intake pipe fixedly connected to the outside of the seat body, not only can the external gas enter the internal position of the guide ring by utilizing the air intake holes provided on the outer peripheral surface of the guide ring, but also after the gas has entered, the residual gas can be synchronously used to push the blades fixedly connected to the outer peripheral surface of the guide ring, and when the blades are pushed, the current guide ring can be synchronously driven to rotate, so that the gas entering the guide ring can be discharged through the wind holes provided in the guide pipe. This design can be effectively linked with the nozzle provided at the bottom of the distribution pipe, so that the gas can generate vortexes through the rotation of the guide pipe when it is sprayed, and can be fully and quickly mixed with the water sprayed by the nozzle.

[0022] 2. In the present invention, when the gas enters the interior of the air inlet pipe, the heat-conducting pipe and the heat-conducting rod can be used to heat the air filled in the air storage pipe, so that the gas inside can be heated to expand and push the guide rod and the piston, so that when it is used, it can realize automatic adjustment of the water flow rate in the current liquid collecting pipe through linkage with the gas, so that when it is used, it can realize automatic adjustment of the amount of water intake by cooperating with the rotation of the guide ring. Compared with the traditional vertex air distribution and the situation where the air intake cannot be adjusted according to the gas circulation rate, this design can make the gas and water more fully contact through the linkage between the water intake and the rotation of the guide pipe to distribute the air, so as to achieve the purpose of improving the purification effect.

[0023] 3. In the present invention, when the baffle and the bottom plate arranged in the collecting pipe move upward due to the expansion of the gas in the gas storage pipe, they can synchronously drive the baffle installed in the discharge pipe to flip, so that it can block the opening of the current discharge pipe in a small range, so that when the gas entering the tower body and the tower cover suddenly increases, the local linkage blocking of the discharge pipe can avoid the situation that the gas entering the tower body and the tower cover will not be discharged through the discharge pipe before being fully purified. Therefore, the linkage of multiple effects can be used to achieve sufficient removal of sulfur dioxide in the gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] 4) When the external gas enters the inside of the air intake pipe 11, when the temperature of the incoming gas is high, the heat will be synchronously conducted to the heat conducting pipe 15 and the heat conducting rod 16 set in the air intake pipe 11, and when the heat enters the internal position of the gas storage pipe 17 fixedly connected to the outside of the manifold 13, the gas in the gas storage pipe 17 will expand due to the high temperature, so that it can push the piston 18 and the guide rod 19 upward, and synchronously drive the bottom plate 20 and the baffle 21 to move upward, so that the flux of the water entering the manifold 13 can be increased, and the flow rate of the purification liquid sprayed by the nozzle 25 can be synchronously increased to achieve rapid spraying;

[0045] 5) Under normal conditions, the baffle 27 rotatably connected to the inside of the discharge pipe 31 is arranged vertically to the discharge pipe 31 through the guide shaft 28.
