Architecture integral type wall-type solar heat-collector

The invention relates to the field of solar buildings, specifically a wall-mounted solar water heater integrated with a building. The wall-mounted solar water heater comprises an irregular box body consisting of light-collecting plates and partitions, a working medium injected into the inner cavity of the box body, and a working medium steam connecting tube and a liquid connecting tube both arranged on the top of the box body. The steam connecting tube is communicated with a working medium steam passage. The liquid connecting tube is communicated with the working medium cavity of the box body.The invention integrates the solar water heater with the walling material and ensures good light-collection effect. The wall-mounted solar water heater can be installed in rural and urban buildings and high-rise buildings to completely or partially replace the southern wall of the building, and can supply domestic hot water and heat sources. The invention promotes the wide application of solar energy ...

Cold-pressed ball using process capable of improving iron smelting recovery rate

The invention provides a cold-pressed pellet using process for improving the iron smelting recovery rate. The cold-pressed pellet using process comprises the steps that firstly, metal oxide, a reducing agent, a desulfurizing agent and a binding agent are fully mixed to be made into pellets; secondly, the pellets are added into reduction equipment according to the first batch to be directly reduced, and when the total thickness of a high material layer reaches the first height, the third step is executed; then the pellets are continuously added into reduction equipment in batches for direct reduction; wherein the batch of each batch is the second batch so as to restrain splashing; when the total thickness of the high material layer reaches the second height, executing the step 4; then the pellets are continuously added into the reduction equipment for direct reduction according to the third batch; and finally, after reduction of all pellets is completed, directly feeding the directly reduced ...
