Multifunctional mobile heat storing and discharging method and mobile heat supplying device

Abstract

The invention belongs to the technical field of mobile heat supplying, and particularly relates to a multifunctional mobile heat storing and discharging method and a mobile heat supplying device. The mobile heat supplying device comprises a water storage tank and a transporter, wherein the water storage tank is fixed on the transporter, a heat exchanging pipe is arranged in the water storage tank, and an inlet and an outlet of the heat exchanging pipe are both located outside the water storage tank, a distribution pipe is further arranged in the water storage tank, multiple spray nozzles are evenly formed in the distribution pipe, and a feeding pipe used for feeding steam or hot water is connected on the distribution pipe. A cold water feeding pipe is connected on the water storage tank, a first pressure gage, a first thermometer and a pressure reducing valve are connected on the water storage tank, a steam outlet pipe is connected with the top portion of the water storage tank, and a hot water outlet pipe is connected with the bottom portion of the water storage tank. The mobile heat supplying device is strong in heat storage capacity, has two heat exchanging modes, namely a direct heat exchanging mode and an indirect heat exchanging mode, can use waste heat and waste gas in various industries widely, and is especially suitable for using the waste heat in the industries to prepare clean saturated water with certain pressure at a certain temperature.

Description

technical field [0001] The invention belongs to the technical field of mobile heat supply, and in particular relates to a multifunctional mobile heat storage and discharge method and a mobile heat supply device. Background technique [0002] my country is rich in industrial waste heat resources, mainly including waste heat of high-temperature exhaust gas, waste heat of cooling medium, waste heat of waste steam and waste water, waste heat of high-temperature products and slag, waste heat of chemical reactions, etc. Waste heat resources account for about 17% to 67% of its total fuel consumption. The recovery rate reaches 60%, the waste heat utilization rate has a large room for improvement, and the energy-saving potential is huge. The characteristics of the current waste heat resources are: due to the periodicity, discontinuity or production fluctuation in the process of production, the waste heat is unstable. The nature of the waste heat medium is bad, such as the dust conten...

Problems solved by technology

At present, the most widely used is the hot water mobile heating device transported under atmospheric pressure within 100 °C. The main advantages of this device are low equipment cost and short heat storage and release time, but the biggest disadvantage is small heat storage capacity and high transportation cost. Poor economic benefits

In addition, some phase change heat storage mobile heating devices are used. The advantages of this device are large heat storage capacity and low transportation cost, but the disadvantages are large equipment investment and long heat storage and release time.
