The invention relates to the technical field of fluid heaters, in particular to a heat pump hot water unit. The heat pump hot water unit comprises a heat storage water tank and a heat pump main engine. A heat insulating layer, a liner and heat exchanging coil pipes are arranged in the heat storage water tank. The heat pump main engine is connected with the heat storage water tank through a circular water pipe. A heat replacing device communicated with the heat storage water tank is further arranged on the heat storage water tank. The liner comprises an upper liner section, a middle liner section and a lower liner section. The middle liner section is of an S-shaped structure. The lower liner section is parallel to the upper liner section in the vertical direction and located on the inner side of the upper liner section. A cylindrical groove is formed in the bottom axis of the lower liner section in a sunken mode. The heat exchanging coil pipes comprise the first heat exchanging coil pipes coiled on the upper liner section, the second heat exchanging coil pipes coiled on the lower liner section and the third heat exchanging coil pipes arranged in the cylindrical groove. The heat pump hot water unit is low in cost, good in energy-saving effect, rapid in temperature rising of the heat pump water tank and high in heat transferring efficiency.

The invention discloses an evaporator effect-enhancing and anti-frosting device, comprising a closed type evaporator, a heating medium inlet, a heating medium outlet, a high-pressure air inlet, a high-pressure draught fan, an environmental air inlet, a high-pressure air outlet, a vortex pipe inlet, a vortex pipe, a cold-air outlet of the vortex pipe, a silencer, a hot-air outlet of the vortex pipe, and a hot-air return pipeline. According to the device, for the working condition of low-temperature heat exchange, the rise of the temperature of pressurized air in the closed type evaporator is realized by using the high-pressure draught fan; as environmental air is subjected to the temperature rise, and then is subjected to heat exchange, so that the heat exchange efficiency is improved, and the frosting or freezing can be prevented; the vortex pipe is adopted for implementing further treatment on high-pressure air flow after the heat exchange; two types of air flow, namely, the high-temperature air flow and low-temperature air flow, are obtained; the high-temperature air flow which still contains the relatively high heat content is reused; with further decrease in the temperature of emitted gas, the heat exchange is relatively thorough and relatively efficient.

The invention belongs to the field of environmental protection, and in particular relates to a process and equipment for graded decomposition, carbonization and harmless treatment of industrial waste salt. The process and equipment of the present invention are aimed at the diversification of organic matter contained in each industrial waste salt and its different physical and chemical properties. Several stages of decomposition and carbonization furnaces are set up to heat the industrial waste salt in stages. Decomposition and carbonization are completed in the carbonization temperature range, and the hot exhaust gas generated by decomposition and carbonization is used as a drying heat source. The exhaust gas generated by drying is introduced into the incinerator for incineration, and the hot gas generated by incineration is recycled. The invention realizes industrial continuous production, no waste salt melting, agglomeration or bonding during system operation, no secondary pollutants, no poisonous and harmful gas emissions, high thermal efficiency, energy saving and environmental protection, and investment cost lower than other methods , has strong practicability, is suitable for organic matter removal and harmless treatment of industrial waste salt in various fields, and is suitable for promotion in industrial production.
