Description

Waste heat recovery unit

Technical Field

The utility model relates to an energy-concerving and environment-protective technical field relates to a waste heat recovery unit particularly.

Background

People only consume about 10 ℃ in the bathing process, but the temperature of the bathing water is 30 ℃, and 2 to 3 times of energy is wasted by directly discharging the bathing sewage after showering. Because the bathroom hot water basically depends on coal combustion to provide heat, the coal can generate a large amount of heat loss and waste gas emission in the combustion process, air pollution can be caused, and a large amount of coal cinder can be remained, so that the bathroom hot water is neither scientific nor economical.

In response to this, the current situation of water availability for ineffective bath was investigated and summarized as follows:

at present, the boiler used at present is a coal-fired boiler, and high-temperature steam generated by a heating gas furnace is mixed with cold water to generate hot water with the temperature of 40-50 ℃ suitable for bathing. Hot water after bathing can be directly discharged into a sewer, a large amount of heat is wasted, and meanwhile, the hot water is directly discharged into an external river, so that the ecological environment of a water body can be influenced, and heat pollution is caused;

bath temperature of the bathroom: the temperature is set to 40-42 ℃ in winter and 36-38 ℃ in summer, and the fluctuation range is small. The temperature of the waste water is about 31-35 ℃, although the outdoor temperature changes greatly in one year, the bathroom has good heat preservation effect, and the waste water recovery is mostly selected at a position close to the bathroom, so the temperature drop is small, and the temperature of 31-35 ℃ used as the temperature of the waste water recovery all year round is reliable.

Total amount of wastewater: the bathroom is used for shower service of customers, and the capacity of the bathroom must meet daily life and business use.

Moreover, the concentration of the coal industry is further improved, a large number of small coal mines are closed, the production of coal is increased slowly, the paid use system of coal resources is reformed to greatly increase the production cost of coal, and the shortage of railway transport capacity and the influence of international coal prices promote the continuous improvement of domestic coal prices. Coal is limited as a non-renewable resource, and because of the inherent property of the coal, the combustion of the coal inevitably generates a large amount of greenhouse gases, which inevitably increase the influence of the greenhouse effect, and obviously, the situation that the coal should be avoided to the utmost extent. Meanwhile, since the 21 st century, water resource shortage and water pollution of China are increasingly aggravated. Along with the continuous extension of schools, the total number of teachers and students in the schools is faster and faster, and the bath water is undoubtedly increased. Therefore, water conservation is imperative.

In summary, the development trend of the coal industry at present is that the use efficiency of coal is improved and coal resources are saved inevitably, and moreover, the discharged hot bath water is always discharged to the outside, the temperature in the water body cannot be well recycled, waste of heat energy resources is brought, and meanwhile, the direct discharge also brings serious thermal pollution and damages the ecological environment.
