Abstract
The utility model relates to boiler desulfurizing equipment, in particular to a boiler sewage recycling system for a semidry process desulfurizing device. The boiler sewage recycling system is characterized in that: boiler sewage discharged from a continuous sewage disposal expander of a boiler is connected to a process water tank of the desulfurizing device through a pipeline. Due to the adoption of the boiler sewage recycling system, the technical problem of incapability of utilizing directly-discharged sewage of the conventional boiler is mainly solved, sewage discharged from the boiler is recycled, circular utilization of waste is realized, and the aims of saving energy and reducing emission are fulfilled.
Description
Technical field
The utility model relates to the boiler blowdown water recycling system of boiler desulfurization equipment, particularly a kind of semidry process desulfurizer.
Background technology
In order to improve steam quality, boiler needs continuously near the stove water surface stove water of salt concentration maximum being discharged, and makes the salt content of stove water be no more than the numerical value of regulation.From the continuous blowdown system of boiler water that drum salt section is drawn, send into continuous blowdown flash tank decompression (because volume increases, pressure decreased makes the vaporization of part sewer), generating portion steam and sewer after the dilatation.Under the present circumstances, this boiler blowdown water all directly discharges, and causes easily environmental pollution, and simultaneously this still have the sewer of 90 ℃ of temperature directly to emit, and causes heat waste, very unfortunate.
The utility model content
The purpose of this utility model is to provide a kind of boiler blowdown water recycling system of semidry process desulfurizer, it mainly solves existing boiler blowdown water and directly emits unavailable technical problem, make the sewer recycling of boiler, realize that recycling waste reaches the energy-saving and emission-reduction purpose.
For achieving the above object, the utility model is to realize like this.
A kind of boiler blowdown water recycling system of semidry process desulfurizer, it is characterized in that: the boiler blowdown water that continuous sewage-discharge volum expander for boiler is discharged is connected to desulfurizer technique water tank by pipeline.
The boiler blowdown water recycling system of described semidry process desulfurizer, it is characterized in that: this desulfurizer is comprised of electric cleaner, desulfurization reaction tower, sack cleaner, desulfurizing agent backflash, desulfurizing agent raw material cabin, desulfurizing agent conveyer, desulfurizing agent transfer pipeline, technique water tank, technique water pump, fresh water (FW) pipeline, fresh water (FW) nozzle, desulfurizing agent nozzle; Wherein, electric cleaner, desulfurization reaction tower, sack cleaner connects successively by boiler flue, the sack cleaner lower end also is connected on the desulfurization reaction tower boiler flue before by the desulfurizing agent backflash, the desulfurizing agent raw material cabin that the desulfurizing agent conveyer is equipped with in the lower end by the desulfurizing agent transfer pipeline be arranged on desulfurization reaction tower before boiler flue in the desulfurizing agent nozzle be connected, the technique water tank that the technique water pump is housed is connected with fresh water (FW) nozzle in being arranged on desulfurization reaction tower by the fresh water (FW) pipeline, a water inlet of technique water tank is connected with running water pipe, and another water inlet then is connected with continuous sewage-discharge volum expander for boiler by pipeline.
Advantage when the utility model uses is.
1, because boiler blowdown water (alkaline water) also is a kind of desulfurizing agent, desulfurizer has increased a kind of auxiliary desulfurization means.
2, because the sewer temperature still has 90 ℃, higher than running water temperature, desulfurizer keeps under the identical flue-gas temperature condition, and boiler blowdown water (alkaline water) can spray more, and desulfurized effect is better.
3, the sewer recycling of boiler realizes that recycling waste reaches the energy-saving and emission-reduction purpose.
