Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of domestic waste terminal treatment, and specifically relates to a novel measuring device for prolonging the service life of a salinity meter electrode. Background Art
[0002] Domestic waste incineration power plants are urban infrastructure and also terminal treatment facilities for domestic waste. Domestic waste is incinerated at high temperature in incinerators every day. The emission of waste incineration flue gas is detected and the salinity is controlled by a salinity meter in a wet method system. Since the electrode of the existing salinity meter is directly installed on the pipeline at the outlet of the coolant circulation pump through a flange, the pumped coolant directly flushes the electrode head-on, resulting in problems of high pressure and high temperature, which cause great damage to the electrode by flushing. Electrode failures often occur, making it difficult to meet production requirements, and serious safety and environmental protection accidents such as excessive flue gas emissions may occur.
[0003] Based on this, how to effectively reduce the flushing of the electrode is the technical problem to be solved in this application. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides a novel measuring device that can effectively reduce the flushing of the electrode to prolong the service life of the salinity meter electrode.
[0005] A novel measuring device for prolonging the service life of a salinity meter electrode provided by the utility model includes a water-receiving outer barrel and a detection inner barrel. The detection inner barrel is arranged in the water-receiving outer barrel, and an annular water-receiving cavity is formed between the detection inner barrel and the water-receiving outer barrel. A cover is arranged at the top of the detection inner barrel, and a salinity meter electrode is installed on the cover. The detection end of the salinity meter electrode extends downward into the detection inner barrel. An overflow partition is arranged in the detection inner barrel to divide the detection inner barrel into a detection chamber and an overflow chamber. The salinity meter electrode is arranged close to the overflow partition and its detection end extends at most to the upper middle position of the overflow partition. A drain pipe is connected to the bottom of the overflow chamber, and a water inlet pipe is installed on the side wall of the detection chamber. The outlet of the water inlet pipe is far from the salinity meter electrode.
[0006] Preferably, an observation hole is further opened at the top of the cover, and an openable hole cover is covered on the observation hole.
[0007] Preferably, the top of the overflow partition is lower than the top of the water-receiving outer barrel, and the volume of the detection chamber separated by the overflow partition is larger than the volume of the overflow chamber.
[0008] Preferably, the water inlet pipe is integrally installed obliquely on the side wall of the detection chamber opposite to the overflow partition, and its outlet faces the bottom of the detection chamber and is lower than the bottom of the detection end of the salinity meter electrode. This inclined installation enables the outlet of the water inlet pipe to be as far away from the detection end of the salinity meter electrode as possible.
[0009] Preferably, the top of the detection inner cylinder is higher than the top of the water receiving outer barrel and is centrally located in the water receiving outer barrel.

[0011] Preferably, the water inlet pipe is provided with a flange connector for connecting with an external pipeline, and the flange connector of the water inlet pipe extends obliquely out of the top of the water receiving outer barrel.
[0012] The utility model is a novel measuring device for extending the life of the salt meter electrode, which is provided with a double arrangement of a water receiving outer barrel and a detection inner barrel:
[0013] On the one hand, the outer water barrel can receive the raw liquid overflowing from the top of the detection inner barrel, preventing the raw liquid from leaking out of the detection device under extreme conditions;
[0014] On the other hand, after the detection inner cylinder is set, the overflow baffle inside it can intercept the overflow, effectively reduce the pressure of the raw liquid, reduce the conduction of the overheating temperature, ensure the continuous and stable normal measurement of the salt meter electrode, ensure the control of the salt discharge valve and the emission of flue gas up to standard, and achieve the safe and environmentally friendly operation indicators of the garbage power plant;
[0015] Moreover, the salt meter electrode is integrally mounted on the cover at the top of the detection device, and its detection end extends into the middle and upper part of the overflow baffle at most. In addition, the outlet of the water inlet pipe is far away from the salt meter electrode. Therefore, compared with the head-on scouring in the prior art, the salt meter electrode measurement in the utility model is not affected by temperature and pressure scouring, thereby achieving the effect of extending the service life and ensuring continuous operation.

DETAILED DESCRIPTION
[0020] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.
[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0022] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selective embodiment that is mutually exclusive with other embodiments.
[0023] Based on avoiding the direct scouring of the original liquid on the salinity meter motor of the wet method system, the present utility model provides a new measuring device for prolonging the life of the salinity meter electrode. Referring to Figure 1 and Figure 2 , in this embodiment, the detection device includes a water receiving outer barrel 1 and a detection inner barrel 2, and the detection inner barrel 2 is arranged in the water receiving outer barrel 1. Specifically, the bottom of the detection inner barrel 2 is welded to the inner bottom wall of the water receiving outer barrel 1, and the top of the water receiving outer barrel 1 is not closed and is in an open state. Thus, a ring-shaped water receiving cavity 3 is formed between the detection inner barrel 2 and the water receiving outer barrel 1. This ring-shaped water cavity 3 can be used to receive the original liquid flowing out from the top of the detection inner barrel 2. Of course, this situation occurs relatively rarely and generally only occurs under extreme conditions. Once it occurs, due to the existence of the ring-shaped water receiving cavity 3, the original liquid will not leak out of the measuring device. It should be noted that Figure 1 and Figure 2 are only simple schematics of the measuring device in this embodiment and are not rigorous product structure diagrams. The purpose is only to facilitate the understanding of the technical solution of the present utility model, and the patterns shown in it should not be construed as a structural limitation of the present utility model.
[0024] To create a closed detection environment inside the detection inner cylinder 2, a cover 4 is provided at the top of the detection inner cylinder 2. It should be noted that a handle can be provided on the top of the cover 4 to facilitate lifting the cover 4 by the handle to open the detection inner cylinder 2 when needed. A salinity meter electrode 5 is installed on the cover 4, and the detection end of the salinity meter electrode 5 extends downward into the detection inner cylinder 2. In this embodiment, a flange is provided at the top of the salinity meter electrode 5, and an installation hole is provided on the cover 4. During installation, the detection end of the salinity meter electrode 5 is inserted into the installation hole, and the flange is stuck on the top wall around the installation hole. Under the fastening action of the fastener, the flange can be locked in the installation hole of the cover 4, thereby realizing the installation of the entire salinity meter electrode 5.
[0025] As an important component of the detection device of the present utility model, an overflow partition 6 is provided in the detection inner cylinder 2 to divide the detection inner cylinder 2 into a detection chamber 7 and an overflow chamber 8. The salinity meter electrode 5 is arranged close to the overflow partition 6 and its detection end extends at most to the upper middle position of the overflow partition 6. A drain pipe 9 is connected to the bottom of the overflow chamber 8, and a water inlet pipe 10 is installed on the side wall of the detection chamber 7. The outlet of the water inlet pipe 10 is far from the salinity meter electrode 5. During detection, after the original liquid flows out from the outlet, it first rises in the detection chamber 7. When the rising original liquid reaches the top of the overflow partition 6, it spreads over the overflow partition 6 and then falls into the overflow chamber 8. During this process, the overflow partition 6 intercepts and overflows the original liquid, which can effectively slow down the pressure of the original liquid and reduce the conduction of overheating temperature. The salinity meter electrode 5 is installed on the top of the cover 4 and its detection end extends at most to the upper middle position of the overflow partition 6. Therefore, the measurement of the salinity meter electrode 5 is not affected by the scouring of the original liquid, and the service life can be effectively extended.
[0026] In addition, it should be noted that through the setting of the overflow partition 6 of the present utility model, the detection inner cylinder 2 is divided into a detection chamber 7 and an overflow chamber 8, avoiding the direct outflow of the original liquid from the outlet of the water inlet pipe 10 to the drain pipe 9, enabling the original liquid to be buffered in the detection inner cylinder 2 and preventing the generation of rapids from directly scouring the salinity meter electrode 5.
[0027] In this embodiment, to facilitate observing the situation inside the detection inner cylinder 2, an observation hole is further provided on the top of the cover 4, and the observation hole is covered with an openable hole cover 11. The hole cover 11 can prevent the original liquid from overflowing. The specific structure of the hole cover 11 can be a rectangular cover, and a pull ring is provided to facilitate pulling open the hole cover 11 for observation.
[0028] To achieve the function of overflow, the top of the overflow partition 6 is lower than the top of the water receiving outer barrel 1, so that the stock solution can spread over the overflow partition 6 and fall into the overflow chamber 8. The volume of the detection chamber 7 separated by the overflow partition 6 is larger than the volume of the overflow chamber 8, so that the detection chamber 7 has a sufficiently large cavity. The stock solution is more likely to obtain buffering in the sufficiently large cavity to avoid forming a rapid flow, further avoiding the erosion of the salinity meter electrode 5.
[0029] To make the outlet of the water inlet pipe 10 as far away from the salinity meter electrode 5 as possible, the water inlet pipe 10 is integrally inclined and installed on the side wall of the detection chamber 7 opposite to the overflow partition 6, and its outlet faces the bottom of the detection chamber 7 and is also much lower than the bottom of the detection end of the salinity meter electrode 5. Thus, through such a design, the stock solution flowing out of the outlet of the water inlet pipe 10 flows towards the bottom of the detection chamber 7, rather than directly flowing towards the detection end of the salinity meter electrode 5.
[0030] In this embodiment, the detection inner cylinder 2 is optimized. The top of the detection inner cylinder 2 is higher than the top of the water receiving outer barrel 1 and is centered in the water receiving outer barrel 1, so that the detection inner cylinder 2 protrudes from the water receiving outer barrel 1, which is conducive to the installation of the cover 4 and the salinity meter electrode 5 on the protruding top.
[0031] When actually installing the detection device of the present utility model, an installation connection frame 12 is provided at the bottom of the water receiving outer barrel 1 to be connected to an external pipeline and a steel structure support. The installation connection frame 12 includes a top support plate 13 and support feet 14 provided at the bottom of the top support plate 13. A through hole (not shown) is provided on the top support plate 13 for the drain pipe 9 to extend out. Through the installation connection frame 12 at the bottom, the entire measuring device can be connected to the external pipeline and the steel structure support, so as to achieve the stable connection and installation of the measuring device.
[0032] It should be noted that in this embodiment, the bottom of the water receiving outer barrel 1 and the bottom of the detection inner cylinder 2 are directly constituted by the top support plate 13, so that the water receiving outer barrel 1 and the detection inner cylinder 2 do not need to be provided with bottoms anymore, thereby reducing the weight of the entire device to a certain extent and reducing the usage amount of the plate.
[0033] As an optimization improvement, the water inlet pipe 10 further has a flange connection head 13 to be connected to an external pipeline, and the flange connection head 13 of the water inlet pipe 10 extends obliquely out of the top of the water receiving outer barrel 1. Through such a design, the connection between the water inlet pipe 10 and the external pipeline is facilitated, and the oblique extension facilitates the overall installation of the water inlet pipe 10 in an inclined state.
[0034] During specific installation and connection, the measuring device is installed on the outlet return pipeline of the coolant circulation pump. The water inlet pipe 10 and the drain pipe 9 are respectively connected to both ends of the return pipe, and the measuring device as a whole is connected to the external pipeline and the steel structure support through the installation connection frame 12, making it a whole.
[0035] Through the cooperative setting of the inner cylinder 2 and the overflow partition 6, the present utility model intercepts and overflows the stock solution, and the stock solution is buffered in the detection chamber 7, reducing the stock solution pressure and the conduction of overheat temperature. In addition, the salinity meter electrode 5 is installed on the top of the measuring device, so that the measurement of the salinity meter electrode 5 is not affected by scouring, thereby achieving the effect of extending the service life.
[0036] The above content further elaborates on the present utility model in combination with specific implementation manners. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
