The cost is too high. With the increasing awareness of environmental protection of the public and the national environmental protection standards, the incineration of urban sludge has become an urgent task of environmental governance.
A desulfurization method for sludge incineration flue gas is provided. Two identical desulfurization units are arranged in the sludge incineration boiler system. Flue gas inlets and hydrogen sulfide outlets are arranged at both sides of the bottom of the outer wall of the desulfurization unit, nitrogen / hydrogen inlets are arranged at the upper part of the outer wall, and flue gas outlets are arranged at the top of the outer wall. The inner part of the desulfurization unit is evenly separated from multiple layers of the same desulfurization reaction room by baffles full of through holes, A spherical desulfurizer made of CuO and Al2O3 is placed in the desulfurizing reaction room, and the weight of the spherical desulfurizer is not less than 1 ton. The two desulfurizing units work by switching valves, and the specific steps are as follows:
Single flange level transmitter_ Desulfurization design of sludge incineration flue gas/ Step 1: the sulfur-containing flue gas generated by sludge incineration at a temperature of 380 ℃ ~ 500 ℃ is fed into a desulfurization unit through the flue gas inlet, and the sulfur-containing flue gas reacts with the spherical desulfurizer in the multi-layer desulfurization reaction room from the bottom to the top, with a reaction time of 2.5s ~ 4S, and then the flue gas conforming to the emission standard after reaction is discharged through the flue gas outlet, and is treated in the desulfurization unit After sulfur-containing flue gas, nitrogen is first introduced through the nitrogen / hydrogen inlet, and then the reacted spherical desulfurizer is cooled to the range of 70 ℃ ~ 80 ℃ by nitrogen, and then hydrogen is introduced through the nitrogen / hydrogen inlet. Hydrogen is used to react with the cooled spherical desulfurizer, so that the spherical desulfurizer can be reused. The hydrogen sulfide gas produced in the reaction process can be returned through the hydrogen sulfide outlet Sludge incineration boiler continues to burn;
Single flange level transmitter_ Design / step 2 of sludge incineration flue gas desulfurization: after the sulfur-containing flue gas is treated by the desulfurization unit, switch over the switch valve, connect another desulfurization unit, and then repeat step 1.
Further, the spherical desulfurizer is prepared as follows: firstly, CuO and Al2O3 with the proportion of 3:1-2:1 are mixed, then the binder of iron powder accounting for 5-10% of the total weight of the mixture is added to make the spherical desulfurizer with the particle size of φ 12-φ 20 mm, which is put into the sintering furnace and sintered at the temperature of 900 ℃ - 1000 ℃ for 40-50 min, and then reduced by 200 ℃ every 10 min. when the temperature drops to below 100 ℃, it is taken Out, naturally cool to room temperature.
Single flange level transmitter_ The design / liquid level (pressure) transmitter of sludge incineration FGD is the economic version of smt3151t, which is suitable for measuring the working condition with large pressure and small pressure. Smt3151lt ? is considered.
Single flange level transmitter_ Design of FGD for sludge incineration / it is a pressure signal measured with atmospheric pressure as the reference end, with one port as flange (or other connection mode) and process pipeline connection. On the basis of the ordinary pressure transmitter, a number of cation membrane boxes are added as the measuring liquid connection part.
Single flange level transmitter_ Sludge incineration flue gas desulfurization design / mainly used to measure high temperature, easy to solidify or crystallize, containing solid suspension, too viscous, corrosive or other media that need to maintain sanitary conditions without pollution loss,
The basic measuring elements have the same technical performance and technical index as 3151t pressure transmitter. After the remote transmission device is added, the measuring accuracy will be slightly reduced, and the speed will slow down. Pay attention to the installation position when the pressure is relatively small,
Ensure that the measured pressure is within the measurement range of the basic measuring element.
In the process of industrial production, the manufacturer of industrial automatic transmitter detects, displays, records or controls the process parameters.
