Detailed Description
A brickyard desulfurization system, as shown in figure 1, comprises a desulfurization tower 1, a recovery tank, a sedimentation tank, a batching tank and a circulating tank, wherein the bottom in the desulfurization tower 1 is provided with the desulfurization tank, a spray pipe 2 is arranged in the desulfurization tower 1, the desulfurization tank, the recovery tank, the sedimentation tank, the batching tank, the circulating tank and the spray pipe 2 are sequentially communicated, an L-shaped communicating pipe 4 is arranged on the desulfurization tower 1, one end of the communicating pipe 4 is positioned in the desulfurization tank, the other end of the communicating pipe 4 penetrates out of the desulfurization tower 1 and is communicated with a large-diameter end of a Laval spray pipe 6, a small-diameter end of the Laval spray pipe 6 is communicated with an air inlet pipe 5, one end of an L-shaped circulating pipe 7 is communicated on the Laval spray pipe 6, the other end of the circulating pipe 7 is communicated with the desulfurization tower 1, a gas detector 8 is arranged in the desulfurization tower 1, the other end of the circulating pipe 7 and the, the gas detector 8 is connected with the electromagnetic valve 9 through a lead. The alarm circuit of the gas detector 8 is connected with the switch circuit of the electromagnetic valve 9 through a lead, so that the purpose that the gas detector 8 controls the electromagnetic valve 9 to be switched on and off is achieved, a control chip can be arranged between the gas detector 8 and the electromagnetic valve 9, the gas detector 8 sends a signal to the control chip, and the control chip controls the electromagnetic valve 9 to be switched on or off after the signal is converted. When sulfur-containing flue gas enters a circulating pipe 7 from an air inlet pipe 5 through a Laval nozzle 6, air flow is accelerated by the Laval nozzle 6 and enters a desulfurization tank for desulfurization, alkaline solution is arranged in the desulfurization tank, and the alkaline solution is formed by dissolving sodium carbonate (soda) serving as an alkaline substance in water according to a proper proportion. After the gas flow is accelerated, the gas flow is fully contacted with water in the desulfurization tank, particularly water in the deep part of the tank or far away from the tank, and the gas flow is quickly mixed, so that the alkaline solution reacts with sulfur dioxide, and the desulfurization effect is improved. The gas which completes the chemical reaction flows upwards, is sprayed by the spraying pipe 2, completes the desulfurization and is discharged. The water sprayed by the spray pipe 2 is soda water, and falls into the desulfurization tank after being sprayed, the water in the desulfurization tank can enter the sedimentation tank through the recovery tank to be precipitated, the mixture (sodium salt) of sulfite and sulfate generated by the reaction of alkaline solution and sulfur dioxide is precipitated to the bottom of the sedimentation tank, and the precipitated sodium salt is reasonably treated. The clear water at the upper part of the sedimentation tank enters a mixing tank, the soda ash is added into the mixing tank according to a proper proportion, and then the clear water enters a circulating tank and then enters a spray pipe 2 through a pipeline and a pump for spraying. When the treated gas does not reach the standard, the gas detector 8 can detect and send a signal to the electromagnetic valve 9, so that the electromagnetic valve 9 is opened, and the gas treated in the desulfurization tower 1 is automatically sucked into the Laval nozzle 6 and enters the desulfurization tank for desulfurization again by utilizing the pressure difference between the Laval nozzle 6 and the desulfurization tower 1, so that continuous circulating desulfurization is formed, and the desulfurization effect is improved.
