Connect the high-temperature circulating pipeline to the pipeline of the booster pump of the heating system of nearby residents and plants, so that the high-temperature circulating water (after heat absorption) can directly enter the heating system incorporated into the user. If it is necessary to reduce the heating temperature, it can be adjusted by adjusting the high-temperature circulating water tower door. In this way, the waste heat of the circulating cooling water can be recycled into the small technical transformation of the heating system, saving energy and creating economic benefits, At the same time, it has also improved the surrounding environment, promoted the construction of energy-saving enterprises, protected the ecological environment and comprehensive utilization of resources.

3.2 利用瓦斯發(fā)電機(jī)組循環(huán)冷卻水的余熱用于附近農(nóng)戶提供農(nóng)業(yè)大棚加熱系統(tǒng)

3.2 use the waste heat of circulating cooling water of gas generator set to provide agricultural greenhouse heating system for nearby farmers

分別接入高低冷卻水池管路至農(nóng)業(yè)加熱大棚骨架母管，通過(guò)加壓泵接入農(nóng)業(yè)大棚骨架母管循環(huán)?？烧{(diào)節(jié)高低溫水池入口閥門大小，來(lái)調(diào)節(jié)加熱骨架母管溫度。通過(guò)在大棚骨架母管的循環(huán)水熱量輻射，使得冬季農(nóng)戶大棚保持適當(dāng)?shù)臏囟?，用于冬季里的農(nóng)業(yè)蔬菜種植。

Connect the high-low cooling water tank pipeline to the framework main pipe of agricultural heating greenhouse respectively, and connect it to the framework main pipe of agricultural greenhouse through booster pump for circulation. The size of the inlet valve of the high and low temperature water tank can be adjusted to adjust the temperature of the main pipe of the heating skeleton. Through the heat radiation of circulating water in the main pipe of the greenhouse skeleton, farmers' greenhouse can maintain an appropriate temperature in winter for agricultural vegetable planting in winter.
