Abstract
The utility model discloses an acid discharging system for a chimney bottom soot-deposition platform, which comprises an acid discharging port (1) arranged in the middle of the chimney bottom soot-deposition platform, the position below the acid discharging port (1) is connected with a poly ethylene (PE) acid discharging pipe (2), the lower end of the PE acid discharging pipe (2) extends into a liquid storage tank (3) arranged under the PE acid discharging pipe, an open hole arranged on one side of the liquid storage tank (3) is connected with a PE pipe to serve as an acid liquor discharging port (4), a backwash device is installed on an open hole arranged on the other side of the liquid storage tank (3), and a sewage discharging port (5) for cleaning deposition at the bottom of the liquid storage tank periodically. The acid discharging system for the chimney bottom soot-deposition platform is simple in structure, reasonable in layout and good in acid-discharging and anti-corrosive effects, and facilitates operation of workers.
Description
Technical field
The utility model relates to a kind of acid dump system of chimney bottom dust stratification platform.
Background technology
The thermal power plant need carry out discharging after desulfurization is handled to flue gas again.Flue gas after the desulfurization is a wet flue gas; The corrosion type of its desulfurization wet flue gas comprises sulfuric acid, sulfurous acid, chloride, fluoride etc.; The flue gas grade is a severe corrosive, and low, the high humidity, little from pull out force of this cigarette temperature almost is in full operation under positive pressure state according to the theoretical calculation chimney.The condensate that the desulfurization smoke condensation forms has very strong corrosivity, and concrete chimney is worked under sour environment, corroded by the multiple action of flue gas pressures and humidity, has a strong impact on chimney safe handling and structure durability.
Chimney bottom dust stratification platform belongs to the privileged sites of this chimney anticorrosion, considers that this engineering is wet desulphurization and does not have GGH, and chimney bottom platform condensation water flow is very big, removes and should carry out the acidproof processing of waterproof preferably, also should be designed with corresponding acid dump system.
The utility model content
The utility model purpose: the purpose of the utility model is to provide the acid dump system of the effective chimney bottom dust stratification platform of a kind of acid discharge.
Technical scheme: the described chimney bottom dust stratification of the utility model platform acid dump system; Comprise and be arranged at the middle acid discharge mouth of chimney bottom dust stratification platform; Said acid discharge mouth below is connected with the PE ACID; In the liquid reserve tank under the lower end of said PE ACID is stretched into; One STH of said liquid reserve tank connects the PE pipe as the acid solution floss hole, and back purge system is installed in the opposite side perforate of said liquid reserve tank, and the below perforate of said liquid reserve tank is equipped with the emissions mouth that is used for the bottom deposit of periodic cleaning liquid reserve tank.
Said acid discharge mouth is arranged on the center of chimney dust stratification platform.
Backwash for ease is connected with skew T on the said PE ACID and is used to install back purge system.
The workman is to the liquid reserve tank place under repair for ease, and said liquid reserve tank is that steel plate is processed, and is installed on the support carrier that is provided with cat ladder; Said support carrier preferably is welded with angle steel.
Said liquid reserve tank inside is provided with glass flake layer and frp layer and combines anticorrosionly, and the outer wall round brush has rust preventive coating.
The diameter of said PE ACID is preferably 200mm, and the back purge system mouth is set to 110mm, and liquid reserve tank bottom emissions mouth caliber is set to 200mm, and acid solution overfall caliber is set to 200mm.
The utility model compared with prior art, its beneficial effect is: the utility model is simple in structure, connection and reasonable arrangement, acid discharge, favorable anti-corrosion effect, and make things convenient for personnel operation.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Be elaborated in the face of the utility model technical scheme down, but the protection domain of the utility model is not limited to said embodiment.
Embodiment 1:The said chimney bottom dust stratification of the utility model platform acid dump system comprises being arranged at the middle acid discharge mouth 1 of chimney bottom dust stratification platform that said acid discharge mouth 1 is two, is separately positioned on the both sides of retaining cigarette wall in the chimney; Said acid discharge mouth 1 below is connected with ￠ 315mm PE ACID 2; In the liquid reserve tank 3 under the lower end of said PE ACID 2 is stretched into; One STH of said liquid reserve tank 3 connects the PE pipe as acid solution floss hole 4, the zone of discharging acid solution to appointment, and back purge system is installed in the opposite side perforate of said liquid reserve tank 3; The below perforate of said liquid reserve tank 3 is equipped with emissions mouth 5, regularly opens the dirt of flange cleaning liquid reserve tank bottom deposit; Be connected with skew T 2-1 on the said PE ACID 2 and be used to install back purge system; Said liquid reserve tank 3 is processed for steel plate, and is installed on the support carrier 7 that is provided with cat ladder 6, makes things convenient for personnel operation; Said support carrier 7 usefulness angle steel are welded; Said liquid reserve tank 3 inside are provided with glass flake layer and frp layer and combine anticorrosionly, and the outer wall round brush has rust preventive coating.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
