Description

Technical Field

[0001] The utility model belongs to the technical field of evaporator auxiliary equipment, in particular to a cleaning mechanism and a cleaning component for a sight glass of an evaporator for preparing agricultural potassium chloride by sintering electrostatic precipitator ash. Background Art

[0002] A large amount of dust is collected in the sintering machine head of the steel enterprise, and the dust is recycled and reused in the industry. Since the dust contains K, a certain proportion of industrial water is added for rinsing during the recycling process of the dust. After purification, the rinsing solution enters the evaporator to evaporate and produce potassium chloride.

[0003] The evaporator for preparing agricultural potassium chloride from sintered electrostatic dust is a type of evaporation and crystallization system commonly used in the chemical, pharmaceutical and wine industries. It is mainly composed of heating chambers, circulation pipes, separation chambers and other containers (static equipment) and circulation pumps, vacuum pumps, pumps and centrifuges (dynamic equipment). According to the downstream direction of steam and materials, the system adopts the circulation pump to force the speed of circulation evaporation.

[0004] In order to observe the amount of solution inside the evaporator, there are several observation windows of different heights on the side wall of the separation chamber, and a transparent sight glass is installed on each observation window. During the operation of the evaporator, due to the influence of temperature and other factors on the saturated evaporated stock solution, part of the precipitated salt will adhere to the inner wall of the sight glass, causing the observation window to be blurred. In serious cases, it is even difficult for the staff to judge the liquid level of the solution in the evaporator, thus affecting production efficiency. Utility Model Content

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] Sintering electrostatic precipitator ash is the dust produced by the high-temperature flue gas from the sintering machine head, blast furnace and converter gas system. The electrostatic precipitator ash contains a large amount of potassium and some iron elements, which has a good utilization value for steel companies.

[0021] During the process of evaporating dust in the evaporator to produce potassium chloride and other products, the sight glass 11 of the evaporator produces partial salt accumulation due to the influence of temperature and other factors on the saturated evaporation stock solution. When the stock solution level drops, the accumulated salt adheres to the inner wall of the evaporator, causing the sight glass 11 for observing the working condition of the evaporator to become blurred, making it impossible to judge the working condition inside the evaporator. The staff is required to manually clean the evaporator after shutting it down, which increases the labor intensity of the staff.

[0022] The utility model discloses a cleaning mechanism for the sight glass of an evaporator for preparing agricultural potassium chloride by sintering electrostatic precipitator ash. Figure 1As shown, it includes a water inlet pipe 21, the water outlet end of the water inlet pipe 21 is located inside the evaporator housing 10, and the water inlet end of the water inlet pipe 21 is located outside the evaporator housing 10; the water outlet end of the water inlet pipe 21 is connected with an elbow 22, and the other end of the elbow 22 faces the inner surface of the sight glass 11 installed in the evaporator housing 10; wherein, the water inlet pipe 21 is connected to a flushing water source.

[0023] The utility model installs a water inlet pipe 21 around the sight glass 11 of the evaporator, and can use the flushing water in the water inlet pipe 21 to flush the sight glass 11, so as to keep the inner surface of the sight glass 11 clear, which is convenient for the staff to observe the liquid page in the evaporator and avoid affecting the production progress.

[0024] In one embodiment, the water inlet pipe 21 is made of a material that does not react with the raw liquid to avoid the water inlet pipe 21 affecting production. It can be a soft pipe body or a hard pipe body. When it is a soft pipe body, it is necessary to meet the support requirements for the elbow 22 to ensure that the flushing water can be accurately aligned with the sight glass 11.

[0025] The elbow 22 may be integrally formed with the water inlet pipe 21 or may be a separate component. The elbow 22 is rotatably connected to the water inlet pipe 21, so that the direction of the elbow 22 can be easily adjusted so that the elbow 22 can be aligned with the inner surface of the viewing mirror 11, and the water inlet pipe 21 can be installed at any position around the viewing mirror 11.

[0026] In addition, the pipe diameter may be gradually reduced from the outer end of the water inlet pipe 21 to the inner end and then to the elbow 22, thereby achieving the purpose of pressurizing the flushing water.

[0027] As a specific implementation method, the water inlet pipe 21 is sealed and connected to the evaporator housing 10 to prevent the original liquid from leaking out from the installation gap. A sealing ring can be added or directly welded.

[0028] Preferably, the water inlet pipe 21 is located above the viewing mirror 11. Thus, the gravity of water can be utilized to reduce the required water pressure of the flushing water.

[0029] In addition, in order to increase the pressure of the flushing water and to make it easier to flush the sight glass 11, a nozzle 23 is installed at the water outlet end of the elbow 22, and the flushing water can be pressurized through the nozzle 23.

[0030] In one embodiment, a control valve is installed on the water inlet pipe 21 and outside the evaporator housing 10. The water inlet amount of the water inlet pipe 21 can be controlled by the control valve, so that water consumption can be saved. In addition, a flow valve can be installed on the water inlet pipe 21 to monitor the water inlet amount, so as to facilitate the calculation of parameters such as the concentration of the solution in the evaporator.

[0031] In summary, the utility model provides a flushing mechanism, which allows water to enter the inner side wall of the evaporator after injection, thereby generating vibration flushing, and flushing and shaking off the crystallized salt produced by the evaporation liquid adsorbed on the inner wall of the evaporator sight glass 11, thereby reducing the probability of the evaporation liquid salt clogging the observation mirror, avoiding the situation where the observation mirror is blurred, and reducing the number of times the staff has to shut down the machine to clean the salt-clogged observation mirror, thereby reducing the labor intensity of the staff.

[0032] The utility model also discloses a cleaning assembly for the sight glass of an evaporator for preparing agricultural potassium chloride from sintered electrostatic precipitator ash, comprising at least one cleaning mechanism for the sight glass of an evaporator for preparing agricultural potassium chloride from sintered electrostatic precipitator ash. Figure 2 As shown, there may be multiple sight glasses 11 in the evaporator, so multiple cleaning mechanisms can be designed in this embodiment to facilitate timely flushing of each sight glass 11.

[0033] In another embodiment, the evaporator unit may be composed of multiple evaporators, and each evaporator may be provided with multiple sight glasses 11, so that the number of the above-mentioned cleaning mechanisms may be greater.

[0034] When there are multiple cleaning mechanisms, the water inlet pipe 21 of each cleaning mechanism can be connected to the same water inlet main pipe to make the pipeline design simpler.
