Description
Technical Field
The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery and utilization system.
Background
Along with the continuous expansion of the dairy cow breeding scale, the intensification degree is greatly improved, and the emission of the dairy cow dung is more concentrated. Therefore, the excrement treatment and utilization mode suitable for the modern dairy cow breeding conditions is selected, and the resource utilization of the excrement is imperative.
The traditional cow dung treatment mode has two types: in the initial stage of cow breeding, the cattle farm is small in scale and is directly transported to the field. Such practice seriously pollutes the environment and the land; airing and fermenting cow dung to produce bed padding, stacking and fermenting cow dung after solid-liquid (dry-wet) separation, and airing to reduce water content to produce the bed padding, wherein the method has two serious defects: (1) the production of bedding materials for lying in bed in winter and rainy season cannot meet the requirements of cattle farms due to factors and influences of weather, air temperature and the like, the materials such as rice husks, sawdust and the like are required to be purchased for supplement, the labor investment is large, and special people are required to carry out airing, turning, stacking, storage and transportation and other works. The labor consumption and the purchase cost are very high, the padding is not fully fermented, and the bacteria inactivation rate and the water content can not meet the use requirements of the bedding for the bed. (2) A large amount of carbon dioxide, ammonia gas and other harmful gases are generated in the open-air fermentation process; the fermentation cylinder mode of taking a breath of the regeneration system of the traditional bed-ridden bedding has a serious drawback: can reduce the tank internal temperature, cause the tank internal temperature unstable, the bactericidal effect seriously reduces, and the effect that produces steam can also reduce moreover, makes the effect that reduces cow dung moisture content discount greatly.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a waste heat recycling system.
In order to achieve the purpose, the utility model adopts the following technical scheme:

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, the waste heat recycling system comprises a fermentation tank body and a preheating mechanism, wherein an air inlet is formed in the outer wall of one side of the fermentation tank body, an air inlet fan is fixedly connected to the inner wall of the air inlet, an air outlet is formed in the outer wall of the other side of the fermentation tank body, an air exhaust fan is fixedly connected to the inner wall of the air outlet, the preheating mechanism comprises a hot air chamber and two electric heating chambers, the two electric heating chambers are arranged at two ends of the hot air chamber, the hot air chamber is communicated with the two electric heating chambers, a plurality of metal pipelines are fixedly connected to the inner wall of the hot air chamber, one end of each metal pipeline is connected to one electric heating chamber through a pipeline, a motor hot chamber is arranged on the air inlet fan through a pipeline, a first air port is formed in the outer wall of one side of the other electric heating chamber, the other end of each metal pipeline is connected to the first air port, a second air port is formed in the outer wall of the top of the hot air chamber, and an air exhaust fan is electrically connected to the hot heating chambers through pipelines, the metal pipeline is linked together with two electric heating chambers, and the discharge gate has been seted up to one side outer wall of the fermentation cylinder jar body, and the feed inlet has been seted up to fermentation cylinder jar body top outer wall.
The working principle is as follows: at the air outlet of the fermentation tank of the bed-lying padding regeneration system, hot air blown out of the fermentation tank of the bed-lying padding regeneration system is collected into a space by a pipeline, so that the temperature in the space is raised. The fresh dry cool air (natural air) is then passed through an electric heating chamber to raise the temperature of the air primarily, and then passed through a metal duct, passing through the high temperature space, and the fresh dry cool air (natural air) is heated secondarily. And conveying the air heated by the second heating step to an electric heating chamber at the other end, heating the air heated by the third heating step, and conveying the air to the interior of the tank body of the bed-ridden padding regeneration system to keep the temperature in the fermentation tank stable.
