Description
Technical Field
The utility model relates to a waste gas treatment field particularly, relates to a collect female pipe.
Background
During the operation of the FGD system, the slurry in the emptying pipeline, the accident slurry pump return pipeline, the filtrate tank pipeline, the absorption tower pit pipeline and other pipelines of the desulfurization area needs to be returned to the absorption tower for recycling, so that the material balance of the whole FGD system is maintained, the reliable and safe operation of the FGD system is ensured, and the FGD area is ensured to be in a clean, civilized and ordered working state. Therefore, a plurality of nozzles need to be arranged on the tower wall of the absorption tower to be correspondingly communicated with the slurry pipelines, so that the manufacturing and installation cost of the absorption tower is increased by the nozzles on the tower wall of the absorption tower, the construction difficulty of corrosion prevention, installation and the like of the absorption tower is increased, the slurry leakage probability is increased by the arrangement of the nozzles, the operation and maintenance amount of the FGD system is increased, the shell strength of the absorption tower is reduced, and the service life of the absorption tower is prolonged.
Disclosure of Invention
In order to solve the problem, the utility model provides a collect female pipe need not set up the return utilization that a great deal of mouth of pipe can realize different pipeline thick liquids on absorption tower wall, has reduced the preparation installation cost of absorption tower, has reduced the operation maintenance volume of FGD system, has improved the shell intensity and the life of absorption tower.
In order to solve the technical problem, the utility model discloses a following technical scheme can realize: the utility model provides a collect female pipe, includes slope section, elbow and straight tube section, is equipped with a plurality of branch pipes on the slope section body, and the slope section lower extreme passes through the elbow to be connected with straight tube section upper end, and straight tube section lower extreme inserts the absorption tower.
Preferably, the inclined section and the straight pipe section form an included angle of 100-140 degrees, and the straight pipe section and the branch pipe are axially and vertically arranged.
Preferably, the upper end of the inclined section is connected with a washing water pipeline through a flange, the lower end of the branch pipe is connected with the inclined section through welding, and the upper end of the branch pipe is connected with an external pipeline through a flange.
Preferably, the inclined section, the elbow and the straight pipe section are equal-diameter pipes, and the pipe diameter of the branch pipe is smaller than that of the inclined section.
Preferably, the inclined section, the elbow, the straight pipe section and the branch pipe are made of homogeneous carbon steel lining rubber and alloy steel corrosion-resistant and wear-resistant materials.
Compared with the prior art, the utility model discloses an advantage is with effective effect: the regional evacuation pipeline of absorption tower, accident thick liquid pump return line, filtrating bath pipeline, absorption tower pit pipeline etc. are connected with the branch pipe that sets up on the slope section body respectively, and the medium in the pipeline is remitted into the slope section through the branch pipe, and then is remitted and flow into the absorption tower, need not set up a plurality of pipeline mouths of pipe on the absorption tower column wall, has reduced the preparation installation cost of absorption tower, has reduced the operation maintenance volume of FGD system, has improved the casing intensity and the life of absorption tower.
Drawings
FIG. 1 is a schematic view of the present invention;
reference numerals: 1. an inclined section; 2. bending the pipe; 3. a straight pipe section; 4. a branch pipe; beta, the included angle between the inclined section and the straight pipe section.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the utility model provides a pair of collect female pipe, including slope section 1, elbow 2 and straight tube section 3, be equipped with a plurality of branch pipes 4 on the 1 body of slope section, the 1 lower extreme of slope section passes through elbow 2 and is connected with straight tube section 3 upper end, and the 3 lower extremes of straight tube section insert the absorption tower.
The inclined section 1 and the straight pipe section 3 form an included angle of 100-140 degrees, and slurry of each branch pipe 4 can be completely discharged at a certain flow rate after being converged into the inclined section 1, so that retention, scaling and pipe blockage of the slurry are effectively avoided; in order to facilitate installation and maintenance, the sealing performance of the connecting surface is ensured, the slurry leakage risk caused by vibration and external factors after long-time operation is avoided, and the straight pipe section 3 and the branch pipe 4 are axially and vertically arranged.
In order to avoid the risks of slurry hanging and scale deposition existing in the inclined section 1 after long-time use, the upper end of the inclined section 1 is connected with a washing water pipeline through a flange, and washing can be carried out in time; the lower end of the branch pipe 4 is connected with the inclined section 1 into a whole by welding, so that the safety, reliability and sealing performance of the connection of the branch pipe 4 and the inclined section 1 can be ensured; the upper ends of the branch pipes 4 are convenient to install and replace through flanges, and can be conveniently connected with an external pipeline according to actual needs.
In order to reduce the on-way resistance and reduce the abrasion of the medium to the pipeline, the inclined section 1, the elbow 2 and the straight pipe section 3 are equal-diameter pipelines, and the pipe diameter of the branch pipe 4 is smaller than that of the inclined section 1.
The utility model provides a pair of collect female pipe, slope section 1, elbow 2, straight tube section 3 and branch pipe 4 are the anticorrosive wear-resisting material of homogeneous carbon steel lining glue, alloy steel, and this type of material is applicable in the relatively abominable thick liquid environment of pH value, and connection rigidity and intensity can be ensured to homogeneous material, can not take place chemical reaction, and the homoenergetic is suitable for between 0.1~1.6MPa pipeline pressure moreover.
