Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde storage, in particular to a formaldehyde tank provided with a heating mechanism. Background Art

[0002] Formaldehyde, also known as formic aldehyde, is an organic compound. Formaldehyde is a colorless gas. It is not easy to detect at low concentrations and can be easily masked by other odors, such as air fresheners. At high concentrations, it has a strong irritating and suffocating odor, which is irritating to the human eyes and nose. Formaldehyde is mostly stored in tanks.

[0003] In the prior art, when the formaldehyde tank is not heated, formaldehyde is prone to polymerize rapidly at low temperatures, especially when it is left stationary for a long time, forming polyformaldehyde, and finally forming granular polyformaldehyde at the bottom of the container; when adding to the system, it causes blockage of the pump filter and jamming and fluctuation of the flow meter, seriously affecting the stable operation of the urea granulation system; and because of the large amount of formaldehyde polymerization, the effective volume of the formaldehyde tank is reduced, affecting the inventory; at the same time, it takes a considerable amount of manpower, material resources and financial resources to deal with the polymerized crystals inside the formaldehyde tank during the annual overhaul. The formaldehyde tank is equipped with internal heating. During long-term operation, the internal heating leaks under the corrosion of formaldehyde, seriously affecting the quality of the steel in the formaldehyde tank, so the heating in the formaldehyde tank is shut down; because formaldehyde is a toxic, flammable and explosive substance, it is impossible to eliminate the heating leakage points in the tank.

[0019] Specifically, the heating mechanism 3 includes an annular liquid distribution pipe 301, a heat exchange pipe 302 and a thermal conductive paste 303. Two annular liquid distribution pipes 301 are provided. The annular liquid distribution pipes 301 are fixedly installed on the inner wall of the outer sleeve 2 near the left and right positions, and the heat exchange pipes 302 are evenly arranged between the left and right annular liquid distribution pipes 301. The heat exchange pipes 302 are connected to the outer surface of the tank body 1, and the outer surface of the heat exchange pipes 302 is provided with thermal conductive paste 303.

[0020] In this embodiment, the high-temperature heat transfer oil in the left annular liquid distribution pipe 301 flows into the heat exchange pipe 302, and then flows into the right annular liquid distribution pipe 301 through the heat exchange pipe 302, so that the heat exchange pipe 302 and the heat conductive paste 303 heat the tank body 1.

[0021] Specifically, a thermal insulation board 12 is fixedly mounted on the inner wall of the outer jacket 2 .

[0022] In this embodiment, the thermal insulation board 12 improves the thermal insulation performance of the outer jacket 2 .

[0023] Specifically, the extraction mechanism 4 includes a pump body 401 and a connecting pipe 402. The pump body 401 is installed on the lower surface of the outer sleeve 2. The liquid inlet and outlet of the pump body 401 are respectively connected to the electric heating box 5 and the left annular liquid distribution pipe 301 through the connecting pipe 402.

[0024] In this embodiment, the pump body 401 draws the high-temperature heat transfer oil heated in the electric heating box 5 into the left annular liquid distribution pipe 301 through the connecting pipe 402.

[0025] Specifically, the control mechanism 7 includes a controller 701 and a temperature sensor 702 . The controller 701 is installed on the front side of the jacket 2 , and the temperature sensor 702 is embedded in the lower side wall of the jacket 2 .

[0026] In this embodiment, the temperature sensor 702 checks the temperature inside the jacket 2 and feeds the information back to the controller 701. The controller 701 heats the heating mechanism 3 according to the temperature inside the jacket 2 to ensure that the heating mechanism 3 effectively heats the tank body 1 so that the formaldehyde in the tank body 1 is at a reasonable temperature.

[0027] Specifically, the boosting mechanism 9 includes a boosting pump 901, an air outlet pipe 902, a check valve 903 and an air pressure sensor 904. The boosting pump 901 is installed on the lower surface of the gas tank 8. The boosting pump 901 is connected to the gas tank 8 through the air outlet pipe 902. The air outlet pipe 902 is provided with a check valve 903. The air pressure sensor 904 is embedded in the right side wall of the tank body 1.

[0028] In this embodiment, when the air pressure sensor 904 detects that the air pressure in the tank body 1 is relatively low, the booster pump 901 injects air into the air tank 8 through the air outlet pipe 902 , and then injects air into the tank body 1 through the conduit 10 .

[0029] When in use, the temperature inside the jacket 2 is checked by the temperature sensor 702 in the control mechanism 7, and the information is fed back to the controller 701. The controller 701 controls the opening and closing of the extraction mechanism 4 according to the temperature change inside the jacket 2. When the temperature is low, the electric heating box 5 heats the internal heat transfer oil, and then the pump body 401 in the extraction mechanism 4 draws the high-temperature heat transfer oil heated in the electric heating box 5 into the left annular liquid distribution pipe 301 in the heating mechanism 3 through the connecting pipe 402. The high-temperature heat transfer oil in the left annular liquid distribution pipe 301 flows into the heat exchange pipe 302, and then flows into the right annular liquid distribution pipe 301 through the heat exchange pipe 302, so that the heat exchange pipe 302 and the heat conductive cement 303 are aligned. The body 1 is heated, and the heat transfer oil refluxes through the reflux pipe 6 to achieve the heating effect on the tank body 1. The tank body 1 heats the formaldehyde, so that the formaldehyde in the tank body 1 is at a reasonable temperature. During the use of the tank body 1, the air pressure sensor 904 detects the air pressure in the tank body 1. When the air pressure in the tank body 1 is too high, the solenoid valve 11 opens, so that the gas in the tank body 1 flows into the gas tank 8 through the conduit 10. When the air pressure in the tank body 1 is too low or discharging, in the boosting mechanism 9, the boosting pump 901 injects air into the gas tank 8 through the outlet pipe 902, and then injects it into the tank body 1 through the conduit 10, which can balance the air pressure in the tank body 1, make the air pressure of the tank body 1 stable, safe to use, and pressurized for easy discharging.

[0030] In summary, the formaldehyde tank provided with a heating mechanism adopts an external heating mechanism 3 to heat the tank body 1, thereby achieving the effect of heating the formaldehyde, avoiding damage to the heating mechanism 3, ensuring the quality of formaldehyde, and at the same time being able to balance the air pressure in the tank body 1, which is safe to use and convenient for discharging.
