Description
Technical field
The utility model belongs to boiler, stove flue gas desulfurization technique field, is specifically related to a kind of efficient cooling desulfurizer structural design that is combined into one with vertical venturi cooling, the suction of impulse mist and the desulfurization of spray turbulent flow.
Background technology
Current, the material that the medium small boiler of China, kiln gas desulfurizer adopt has two kinds usually: numb stone or carbon steel add corrosion-proof lining.
The desulfurizer of fiber crops work made of stones, though it is low to have a cost, resistant to elevated temperatures advantage, single its shortcoming is also clearly, not only desulfuration efficiency is low, and floor space is big, and outward appearance is coarse, and the vulnerability because of binding material causes sealing poor between the numb barnacle piece, and this body drain cigarette leaks, and causes secondary pollution.The use of present numb stone is little by little replaced by light material.
Carbon steel adds the desulphurization plant of corrosion-proof lining, lightweight and portable in volume, floor space are little, but because inner lining material (no matter being rubber or glass flake) non-refractory, (temperature is usually about 140 ℃ can not to bear the high-temperature flue gas of boiler emission, have up to 190 ℃), need before desulphurization plant, install heat sink additional usually.Traditional drum type brake spraying cooling device, the cooling volumetric ratio (is meant the heat exchange amount of cooling tower and the ratio of its volume, J/m
3) very low, the volume of the required equipment of lowering the temperature is very big.And the material of this heat sink can only be selected very high special stainless steel of Unit Weight price (as 316L, 317L) or special nickel-base steel alloy (as C276) for use.In this case, the manufacturing cost of this device will be very high.
Mechanism designs such as the internal structure great majority utilization inertial collision of medium small boiler, kiln gas desulfurizer, centrifugal moisture film, hollow-spraying-tower, eddy flow plate, sieve tray, filler.With hollow-spraying-tower the most commonly used is example, facts have proved, its desulfurized effect wants to reach the requirement (SO of the DB11/139 emission standard of air pollutants for boilers of implementing Beijing
2Concentration of emission is lower than 150mg/Nm
3), the spray number of plies need design the 4-6 layer, has not only increased equipment resistance, and has caused the ratio of height to diameter of tower also very inharmonious.
Therefore, exploitation can be satisfied the requirement of high-efficiency desulfurization, can reduce cost again and the incorporate efficient cooling desulfurizer of more efficiently combined type of floor space is that the environment-friendly engineering technical staff is badly in need of the problem that will study and solve.
