Abstract
The utility model discloses a device for on-line detecting alum concentration during tap water production. The device comprises two alum solution supply pools and a dual-flange type pressure difference transmitter; the alum solution supply pools are communicated with each other through a pipeline; a reverse-flow type communicating pipe is connected on the pipeline; and the reverse-flow type communicating pipe is connected with the dual-flange pressure difference transmitter. The utility model utilizes the communicating pipe between the alum solution supply pools and adopts a reverse-flow type communicating device for mounting the differential pressure transmitter, the on-line detection for pressure of alum solution is achieved, and the concentration of the alum solution can be calculated out through the relations among the pressure difference, and the liquid level and liquid weight. Therefore, the purpose of on-line detecting the concentration of the alum solution is achieved. The on-line pressure difference detecting device not only can detect the specific weight (concentration) of alum, but also avoid destroying on the structure of each alum pool.
Description
Technical field
The utility model belongs to pick-up unit, is specifically related to the on-line measuring device of alum concentration in a kind of tap water production.
Background technology
Throwing alum is the core process technology that tap water is produced, and general former alum will dilute after entering factory, and water is mixed with certain concentration and uses for throwing alum.If the concentration instability of alum will cause interference to production run, serious will influence production safety.In the tap water production run, do not have the real-time online detection of carrying out at present, so the concentration of alum can't realize detecting in real time adjusting in the tap water production run for the concentration of joining alum.
Summary of the invention
The purpose of this utility model is to provide the on-line measuring device of alum concentration in a kind of tap water production, to realize the online in real time detection to alum concentration, to address the above problem.
The technical solution of the utility model is: the on-line measuring device of alum concentration during tap water is produced, it comprises two alum solution supply reservoirs, two flange form pressure difference transmitters, connect UNICOM by pipeline between two alum solution supply reservoir bottoms, connect refluence formula cross over pipe on the pipeline, refluence formula cross over pipe is connected with two flange form pressure difference transmitters.
Refluence formula cross over pipe vertically is provided with, and refluence formula cross over pipe is offered alum solution pressure detection pipe up and down respectively, and refluence formula cross over pipe up and down two alum solution pressure detection pipe external flanges is connected with two pressure measurement flanges on two flange form pressure difference transmitters respectively.
This patent has utilized the unicom pipeline between two alum solution supply reservoirs to design a refluence formula intercommunicating device dexterously, differential pressure transmitter is installed, the detection of the online differential pressure under the liquid level condition is decided in realization to alum liquid, pass through pressure reduction, relation between the weight of liquid level and liquid calculates the concentration of alum solution, thereby realizes the online detection of alum solution concentration.This line pressure device for detecting difference can either online detection alum proportion (concentration), can not destroy the structure in alum pond again.
Description of drawings
The online pressure test device synoptic diagram of alum concentration during Fig. 1 tap water is produced.
Fig. 2 two pressure measurement flange connection diagrams on formula cross over pipe and the two flange form pressure difference transmitters that flow backwards.
Embodiment
As shown in Figure 1, the waterworks join the alum pond that the alum pond is bottom, two a pond UNICOM, one of them alum solution supply reservoir 2 is big for the alum amount, liquid level descends fast, another alum solution supply reservoir 1 liquid level descends slow, two alum solution supply reservoirs connect UNICOM by the bottom for alum pipe 3, realize the alum solution that alum solution supply reservoir 2 replenishes to the fast alum solution supply reservoir 1 of liquid level decline like this.For vertically connecting UNICOM's refluence formula cross over pipe 4 on the alum pipe 3, refluence formula cross over pipe 4 is offered alum solution pressure detection pipe 5,6 up and down respectively; Refluence formula cross over pipe about in the of 4 two alum solution pressure detection pipes 5,6 respectively with two flange form pressure difference transmitters 7 on two pressure measurement flanges 8,9 be connected (as shown in Figure 2).The inlet of the bottom of refluence formula cross over pipe 4 is connected UNICOM with the pipeline of alum solution supply reservoir 1 at a slow speed, and the liquid outlet on the top of refluence formula cross over pipe is connected UNICOM with the pipeline of alum solution supply reservoir 2 fast.The height of refluence formula cross over pipe 4 is no more than the liquid level of the alum solution in the alum solution supply reservoir, and the height of the liquid outlet on refluence formula cross over pipe top and connecting pipe 3.1 is no more than the liquid level of the alum solution in the alum solution supply reservoir 1 in the present embodiment.
In actual production process, the liquid level of alum solution supply reservoir 1 is slightly higher than the liquid level of alum solution supply reservoir 2, so the alum solution of alum solution supply reservoir 1 can flow to alum solution supply reservoir 2 by refluence formula cross over pipe 4.Two flange form pressure difference transmitters 7 detect the pressure of the alum solution pressure detection pipe 5,6 of refluence formula cross over pipe about in the of 4 by two pressure measurement flanges 8,9, obtain both pressure reduction, thereby can calculate the concentration of alum solution.
Simpler about the calculating liquor ratio of trying to achieve concentration by differential pressure:
ΔP＝ρ×H，
In the formula, Δ P is a differential pressure value, and ρ is the severe of liquid, and H is a liquid level, is a constant, so Δ P is directly proportional with ρ, can be by ρ is tried to achieve in the test of Δ P, because the severe ρ of the alum of 100% concentration
0Be a constant, ρ
0: ρ=100%: X%, and try to achieve the online concentration of alum solution.
