Description

Power plant industrial wastewater pH value measuring device

Technical Field

The utility model relates to an industrial waste water detects technical field, concretely relates to industrial waste water pH value measuring device of power plant.

Background

The method for realizing zero discharge of desulfurization wastewater applied to domestic power plants mainly comprises the following steps: multiple-effect evaporative crystallization, MVR evaporative crystallization, reverse osmosis treatment and crystallization matching, forward osmosis membrane treatment and crystallization matching and flue spray evaporative crystallization. The desulfurization waste water zero-main-discharge spraying system adopting the flue spraying, evaporating and crystallizing process utilizes flue gas of a main flue behind an air preheater to evaporate desulfurization waste water, thereby achieving the purpose of zero discharge of the desulfurization waste water.

In the prior art, because the wastewater pool has large area and deep depth, the traditional PH meter mounting mode is that a bracket is mounted at the pool edge and a protection barrel provided with a PH meter probe is fixed at the pool edge. The field installation mode is as shown in figure 1, the protection cylinder is fixed at the pool edge, the PH meter is arranged at the joint of the lower end of the protection cylinder, and the transmitter is arranged on the guardrail bracket at the pool edge. The problems existing in the prior art are as follows: 1. the water sample point that the PH meter was measured is a certain fixed point of protection bobbin base portion, because the industrial wastewater disposal basin area is big, and the degree of depth is dark, causes the sample point can not accurately reflect the appearance water PH value in whole pond. 2. The PH meter probe is fixedly arranged at the bottom of the water pool for a long time and easily adheres dirt to the electrode, so that the measured value is deviated. 3. Because the PH meter needs to be checked regularly, the whole protection cylinder needs to be pulled out of the water surface to take out the electrode. The protective cylinder is too heavy, so that great inconvenience is brought to the checking work, and when the checking is finished and the installation is recovered, the buoyancy is quite large when the protective cylinder is put into water because the protective cylinder is a well-sealed closed space. More importantly, the sealing performance of the joint of the electrode and the protection cylinder is reduced due to the fact that the number of times of checking is increased, sample water permeates into the protection cylinder, so that the cable is affected with damp, and the output value is deviated from the actual measurement value.

Disclosure of Invention

An object of the utility model is to provide a power plant's industrial waste water pH value measuring device, the device not only are favorable to improving the measurement accuracy, and it is convenient to use moreover, easy to maintain.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a power plant's industrial waste water PH value measuring device, includes registration arm, floater, tray, PH meter and changer, the vertical setting of registration arm, and its upper end is fixed in the wastewater disposal basin inward flange through the mounting bracket, the changer is installed on wastewater disposal basin limit support, the tray floats on the surface of water and locates on the registration arm through the haulage rope cover to make the tray can be at the length within range free activity of haulage rope, and can float about following the water level change, the floater sets up on the tray, the PH meter is inserted and is arranged in on the floater, and its lower extreme passes through the through-hole on the tray and inserts the aquatic, and its upper end is connected with the changer through the cable.

Furthermore, the lower end of the PH meter is connected with a heavy hammer, so that the PH meter is vertical to the water surface and the lower end of the PH meter is always inserted into the water.

Further, the positioning pipe is a galvanized pipe.

Further, be connected with a connecting rope on the tray, connecting rope upper end is connected on the mounting bracket to pull up the tray when needs.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a power plant's industrial waste water pH value measuring device, the device sampling range is big, can reflect the pH value of waste water in the whole pond more accurately, and the cable is difficult to appear the problem of weing, can not influence actual measuring result to measuring accuracy has been improved. In addition, the device is convenient to use, especially takes out the PH meter when being convenient for maintain and carries out periodic check, need not to consume a large amount of labours and takes out the protection section of thick bamboo, and can not exert an influence to equipment reuse, consequently, has very strong practicality and wide application prospect.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a power plant's industrial waste water pH value measuring device, as shown in figure 2, including registration arm 1, floater 2, tray 3, PH meter 4 and changer 5. Changer 5 installs on wastewater pool limit support, 1 vertical settings of registration arm, and its upper end is fixed in the wastewater pool inward flange through mounting bracket 6. In this example, a one inch diameter galvanized pipe was used as the positioning pipe. The tray 3 floats on the water surface and is sleeved on the positioning pipe 1 through the traction rope 7, so that the tray 3 can freely move within the length range of the traction rope 7 and can float up and down along with the change of the water level. The floater 2 is arranged on the tray 3, the PH meter 4 is inserted on the floater 2, the lower end of the PH meter is inserted into the water through a through hole on the tray 3, and the upper end of the PH meter is connected with the transmitter 5 through a cable 8.

In the preferred embodiment of the present invention, the lower end of the PH meter 4 can be connected to a weight so that the PH meter is perpendicular to the water surface and the lower end thereof is always inserted into the water. A connecting rope can be connected to the tray 3, and the upper end of the connecting rope is connected to the mounting frame so as to pull up the tray when needed.

The device cancels the original PH meter protection barrel, is replaced by a positioning tube with smaller diameter, and can be fixed in the water pool for a long time without being taken out. When the PH meter is checked, the water surface of the PH meter can be directly pulled out through the cable, and checking is convenient.
