Abstract
Description
Technical Field
[0001] The utility model relates to a heating device, in particular to hot air steam electric heating equipment. Background Art
[0002] Trichloroisocyanuric acid is a highly effective disinfectant bleaching agent with stable storage, convenient and safe use. It is widely used in food processing, drinking water disinfection, sericulture and rice seed disinfection. It has a killing effect on almost all fungi, bacteria, and virus spores, and has a special effect on killing hepatitis A and hepatitis B viruses. It also has a good disinfection effect on sexually transmitted viruses and HIV. It is safe and convenient to use. It has been used as a disinfectant in industrial water, swimming pool water, cleaning agents, hospitals, tableware, etc., and as a sterilant in sericulture and other breeding. In addition to being widely used as a disinfectant and bactericide, trichloroisocyanuric acid is also widely used in industrial production. Trichloroisocyanuric acid needs to be dried during the processing process to evaporate the internal water, and drying trichloroisocyanuric acid requires 250°C hot air. In order to reach the required heating temperature, electric heating is generally used, which will not only greatly increase power consumption, but also the temperature span is large and difficult to accurately control, and is not conducive to heat recovery in chemical companies. Utility Model Content
[0003] In order to solve the above problems, the purpose of the utility model is to provide a hot air steam electric heating device.
[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a hot air steam electric heating device, comprising a horizontal box body with openings at both ends and a steam heating pipe arranged in the box body, the steam heating pipe extending from the air inlet end of the box body to beyond the middle part of the box body, the steam heating pipe having multiple vertical groups, each group separated by a partition, each group of steam heating pipes is connected to an external air supply pipeline through a corresponding valve, and adjacent partitions are arranged alternately up and down, so that a steam heating chamber that meanders up and down is formed in the box body through which the steam heating pipe passes, an electric heating chamber is formed at the air outlet end of the box body, multiple rows of electric heating wires are arranged at intervals in the electric heating chamber, and detection chambers are left in the box body between the steam heating chamber and the electric heating chamber, and a moisture detection sensor and a first temperature sensor are respectively arranged in the detection chamber.
[0005] Furthermore, the vertical portion of each steam heating pipe is a spiral pipe.
[0006] Furthermore, the air inlet end and the air outlet end of the box body are respectively provided with a conical air guide cover which gradually tapers outwards.
[0007] Furthermore, a second temperature sensor is also provided at the air outlet end of the box.
[0008] Furthermore, the outer side wall or the inner side wall of the box body is covered with a heat insulating material.
[0009] Furthermore, a support frame is provided at the bottom of the box body, and a plurality of columns are supported at the bottom of the support frame.
[0010] The vertical part of each steam heating pipe of the utility model is a spiral pipe, each group is separated by a partition, each group of steam heating pipes is connected to the external air supply pipe through a corresponding valve, and the adjacent partitions are arranged in an up-and-down staggered manner, so that a steam heating chamber that is circuitous up and down is formed in the box through which the steam heating pipe passes. This structure allows the air to fully contact the steam heating pipe when it flows through the steam heating pipe part, thereby ensuring the heat exchange effect and facilitating the subsequent electric heating temperature control;
[0011] That is, a two-stage heating method is adopted. Steam heating can only be heated to 140-150℃, and then heating is performed through the electric heating wire. This can significantly reduce the burden on the electric heating wire, and a detection cavity is reserved in the box body of the steam heating cavity and the electric heating cavity. A moisture detection sensor and a first temperature sensor are respectively arranged in the detection cavity. The first temperature sensor and the second temperature sensor ensure that each stage of temperature meets the process indicators. Not only can the steam be fully utilized for preheating, the consumption of electric energy is reduced, which is more energy-saving and environmentally friendly, but also after the pre-temperature increase, the temperature control range of the subsequent electric heating is smaller, which is convenient for control through electric heating and the temperature control is more precise.
