Description

Technical Field

[0001] This utility model relates to the production of aqueous fertilizers, and more specifically, to a high-thermal-efficiency aqueous fertilizer production vessel. Background Technology

[0002] The aqueous fertilizer production vessel is the core equipment for aqueous fertilizer production. Existing aqueous fertilizer production vessels, such as the reactor disclosed in CN218107666U, can also be used for aqueous fertilizer production, but they are only suitable for small-scale production, with small feed volume and poor sealing performance. The jacket of the reactor only has a cooling function, and heat preservation requires the installation of a layer of heat preservation material on the outside of the reactor. The installation of heat preservation material is not conducive to heat dissipation and heat absorption, resulting in low thermal efficiency and high overall energy consumption.

[0029] In one or more embodiments of this utility model, an electric regulating valve for returning material is installed on the return pipe 11 to facilitate automated control of the return material.

[0030] In one or more embodiments of this utility model, in order to facilitate sampling, a sampling tube 13 is connected to the discharge pipe 6, and a sampling manual valve is installed on the sampling tube 13.

[0031] In one or more embodiments of this utility model, in order to make the reactants in the vessel body 1 reach the reaction temperature, a first steam pipe 19 is connected to the vessel body 1.

[0032] In one or more embodiments of this utility model, in order to make the reactants in the vessel body 1 reach the reaction temperature, a steam coil system 18 is provided on the inner wall of the vessel body 1, and the steam coil system 18 is connected to a second steam pipe 20.

[0033] In one or more embodiments of this utility model, in order to facilitate automated control of material return, a first steam electric regulating valve is installed on the first steam pipe 19, and a second steam electric regulating valve is installed on the second steam pipe 20.

[0034] In one or more embodiments of this utility model, in order for the steam coil system 18 to operate normally, the steam coil system 18 is also connected to a drain pipe 21, and a drain valve is installed on the drain pipe 21.

[0035] In one or more embodiments of this utility model, in order to monitor the reaction state inside the reactor in real time, a reactor medium temperature sensor 22, a reactor medium density sensor 23, and a reactor medium pH sensor 24 are respectively installed inside the reactor body 1.

[0036] In one or more embodiments of this utility model, in order to monitor the weight change of the material in the reactor in real time, a weighing bracket 25 is connected to the outer wall of the jacket 2, and a weighing sensor 26 is connected to the lower surface of the weighing bracket 25.

[0037] In one or more embodiments of this utility model, in order to increase the feeding amount and improve the sealing performance after feeding, the feeding port 7 is relatively large, and a sealable pneumatic opening and closing cover 27 is installed on the feeding port 7. Those skilled in the art should understand that when the pneumatic opening and closing cover 27 is closed, the technology of sealing the pneumatic opening and closing cover 27 with the vessel body 1 is prior art in this field. The pneumatic opening and closing cover 27 and the vessel body 1 can be connected by friction sealing or by other sealing methods, which are not specifically specified in this application.

[0039] In this invention, vacuum insulation is used. After closing the cooling water drain valve and cooling water solenoid valve in jacket 2, the vacuum solenoid valve is opened to evacuate the jacket 2 for insulation. Once the vacuum level reaches ≤0.008 atmospheres, the vacuum solenoid valve is closed, and the vessel body 1 is then vacuum-insulated. When insulation is no longer needed, the vacuum solenoid valve is opened to release pressure and stop the insulation process. After the reaction is complete and cooling is required, the vacuum valve is opened to bring the pressure inside jacket 2 to atmospheric pressure, and the cooling circulating water is turned on, resulting in rapid cooling. Using vacuum insulation, and controlling the insulation through vacuum evacuation and depressurization, significantly reduces energy consumption and saves time.

[0040] In this invention, when the reaction requires heating, the second steam electric regulating valve is opened to heat exchange the material in the reactor with a steam coil. When the added water can submerge the steam pipe inlet, the first steam electric regulating valve is opened. When the amount of steam introduced reaches the required level, the first steam electric regulating valve is closed. If the temperature has not yet reached the required level, the second steam electric regulating valve continues to heat the coil. When the temperature reaches the required level, the second steam electric regulating valve is closed.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
