Description
Technical Field
The utility model relates to a liquid medicine liquid feeding pipe-line technical field especially relates to a sewage treatment plant sedimentation tank liquid medicine liquid feeding pipe-line system.
Background
The method for adding the total phosphorus in the sewage tank in the test operation is characterized in that the Yiwei phosphorus powder and water are mixed in a certain proportion and then added, the powder is found to be unsuitable for the water quality condition of the factory in the actual operation, particularly, the total phosphorus in the effluent is difficult to control, and after negotiation with a medicament factory, the water quality is found to be more suitable and easy to operate by adopting the polymeric ferric sulfate after small test analysis.
The preparation flow of a Miton Ro metering pump adopted by the existing design is 583L/H, and the pump is initially designed to feed powder (the powder concentration is low, the feeding amount is large, the density of an aqueous agent is high, and the feeding amount is small); when the powder is used, the minimum adding amount is 60L/H, the actual adding amount of the polyferric sulfate adopted by the factory only needs about 3.6L-12L/H, and when the powder is added, the powder and water are diluted and then flow to the water outlet of the oxidation ditch and the IBR water inlet channel through pipelines; therefore, in actual operation, the dosage pump power needs to be adjusted to the lowest when the water aqua is used, but the dosage is still too large relative to the water quality of the factory when the dosage of the pump is adjusted to the lowest, the biochemical system and the sludge activity are influenced, and the pump is operated for too long time to the lowest flow, so that the pump is overheated, the automatic stop condition occurs in the operation, and the normal administration cannot be performed.
In order to solve the above problems, an adjustable control valve is installed in the pipeline of the oxidation ditch, but the pumping amount is too large, and the flow rate of the other flow direction is too small, so that the overstocked pressure is too large, the pipeline is broken, and the valve automatically falls off, so that the pipeline needs to be repaired frequently.
Therefore, the chemical liquid adding pipeline system of the settling tank of the sewage treatment plant is designed based on the situation.
Disclosure of Invention
The utility model aims to overcome the not enough of prior art, adapt to reality needs, provide a sewage treatment plant sedimentation tank liquid medicine liquid feeding pipe-line system of structural design novelty, simple, easy to carry out.
In order to realize the utility model discloses a purpose, the utility model discloses the technical scheme who adopts does:
designing a liquid medicine feeding pipeline system of a sedimentation tank of a sewage treatment plant, which comprises a dosage pump, a liquid inlet pipe connected with the dosage pump, and a liquid outlet pipe connected with an outlet of the dosage pump; the method is characterized in that: still include medicine storage tank, medicine storage tank export and feed liquor pipe intercommunication, feed liquor pipe still communicates with the delivery pipe, be connected with the back flow on the drain pipe middle part, the drain pipe passes through the back flow and constitutes the return circuit with feed liquor pipe intercommunication, and is equipped with back flow control valve on the back flow.
And a pressure gauge is also arranged on the liquid outlet pipe.
The outlet of the medicine storage tank is communicated with the liquid inlet pipe through a regulating valve.
The beneficial effects of the utility model reside in that:
this design is through increasing the back flow on the drain pipe and realizing discharging under the condition of not changing measuring pump power that the liquid medicine flow is controllable, has solved the actual problem that present my factory meets at present.
Drawings
FIG. 1 is a schematic diagram of the main principle of the present invention;
fig. 2 is a schematic diagram of a structure of the dispersing pipe according to the present invention.
Detailed Description
The invention will be further described with reference to the following figures and examples:
example 1: a liquid medicine adding pipeline system of a sedimentation tank of a sewage treatment plant, which is shown in figure 1.
It includes dosage pump 4, feed liquor pipe 3 be connected with dosage pump 4, with dosage pump 4 exit linkage's drain pipe 5, still includes medicine storage tank 1, and the liquid medicine is located medicine storage tank 1, in this design, medicine storage tank 1 export and feed liquor pipe intercommunication, simultaneously, medicine storage tank export is through 2 and 3 intercommunications of feed liquor pipe of governing valve, through the volume in 2 steerable medicine storage tanks of governing valve liquid medicine entering feed liquor pipe 3.
Furthermore, the liquid inlet pipe 3 is communicated with a water supply pipe, a return pipe 6 is connected to the middle of the liquid outlet pipe, the liquid outlet pipe is communicated with the liquid inlet pipe through the return pipe 6 to form a loop, a backflow regulating valve 7 is arranged on the return pipe, a pressure gauge is further arranged on the liquid outlet pipe, redundant liquid medicine in the liquid outlet pipe is input into the liquid inlet pipe again through the return pipe to form loop circulation in use, and therefore the dosage pump 4 can keep low-power operation and the situations of large pressure and pipe explosion of the liquid outlet pipe cannot occur.
In summary, the reflux pipe is additionally arranged at the outlet end of the dosage pump, so that the direction of the pipeline on two sides can be divided when the dosage is large, and a plurality of parts flow to the reflux pipe, enter the pipeline and then flow to the medicine storage tank. The adjusting valve 2 is a PPR adjustable valve (polymeric ferric sulfate has strong corrosivity to metals, so the valve is made of PPR materials) and can be used for adjusting the adding size of a phosphorus removal medicament, the controllable and adjustable medicament amount is realized, and the influence of the overlarge medicament amount on a biochemical system and the sludge activity is avoided.
Embodiment 2, see fig. 2, the same as embodiment 1 will not be described again, except that:
this design is connected with dispersion tube 8 on the feed liquor pipe in 1 the place ahead of storage medicine jar, and the entrance point of dispersion tube 8 is the water inlet, and the play water end and the feed liquor union coupling of dispersion tube 8 are connected with inlet 11 on the feed liquor pipe in 8 delivery port departments of dispersion tube simultaneously, inlet and governing valve 2's exit linkage, and is further, its the hole at 8 middle parts of dispersion tube is through middle part to both ends crescent, also is the hole at 8 middle parts of dispersion tube through minimum, so, the hole that rivers pass through 8 middle parts of dispersion tube is after to the velocity of flow increase, and in the liquid medicine passes through inlet 11 entering feed liquor this moment, liquid medicine and rivers contact and the rivers that increase through the velocity of flow were to the liquid medicine dispersion and carry forward this moment.
The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
