The present invention utilizes water source heat pump technology in beer fermenting tank cooling step. The water source heat pump set has one side connected to the beer fermenting tank so as to cooling the fermenting tank with the heat pump refrigerator, and other side connected to boiler water replenishing tank so as to preparing hot water at 50 deg.c with the heat pump condenser. The hot water may be used to provide hot water to other step and provide water to boiler oxygen eliminator. The water source heat pump technology can utilize full heat and save energy at most.

The invention relates to a boiler waste heat recovery device, which comprises a boiler return water tank and a heat absorption tank installed on a flue. Among them, the heat absorbing tank is provided with a flue gas channel extending from the bottom of the heat absorbing tank to the top of the heat absorbing tank, a plurality of heat absorbing steel pipes are arranged inside the heat absorbing tank, and water inlets and outlets are provided on the outer wall of the heat absorbing tank. The water inlet and the water outlet are respectively connected to the boiler return water tank through pipes. The invention realizes secondary recovery and reuse of boiler waste heat, greatly increases boiler inlet water temperature, achieves the goals of coal saving, energy saving and environmental protection, and reduces cost while improving boiler thermal efficiency.

The invention discloses a water storage tank circular seam structure and a manufacturing method thereof, and relates to the technical fields of high-capacity power station boiler water storage tank designing and manufacturing. The problems that an existing water storage tank circular seam structure is single in manufacturing method and lag in manufacturing technology, thus, a manufactured water storage tank is large in wall thickness margin, serious in inner surface wall thickness decreasing, discontinuous in structure and poor in machining quality are solved. According to the water storage tank circular seam structure, a water storage tank comprises two sealing heads and a plurality of barrel sections, all the barrel sections are sequentially spliced into a barrel body along the axes of the barrel sections, the two sealing heads are arranged at the two ends of the barrel body correspondingly, the ovality of the barrel body and the sealing heads is +/-0.6mm, and the thickness deviationbetween the barrel body and the sealing heads is 0-2mm; and a butt-joint circular seam groove is formed between every two adjacent barrel sections, a butt-joint circular seam groove is formed betweeneach sealing head and the corresponding barrel section adjacent to the sealing head, and the butt-joint circular seam grooves are connected through a welding mode. The manufacturing method is used for manufacturing of the water storage tank circular seam structure.

The invention relates to the field of power plant hydration technologies, in particular to an intelligent control system and method for boiler water quantity of a hydration workshop. According to thetechnical scheme, the intelligent control system for the boiler water quantity of the hydration workshop comprises a main controller, wherein the main controller comprises a standard water quantity presetting module, a water quantity detecting module, a water quantity comparison module and an adjusting module. The intelligent control method for the boiler water quantity of the hydration workshop comprises the following steps that the standard water quantity of a boiler is preset, timely water quantity of the boiler is detected, the timely water quantity of the boiler is compared with the standard water quantity in real time, and connection and disconnection of a water inlet pipe or a water outlet pipe is controlled according to a water quantity comparison result. According to the intelligent control system and method for the boiler water quantity of the hydration workshop, the problems that the boiler water quantity of an existing hydration workshop can only be manually adjusted, so that adjustment is not timely and is low in precision.

The invention relates to an operation method of a vertical waste heat boiler for flue gas treatment of a glass melting furnace. The downpipes connected to one side of the steam drum of the vertical waste heat boiler connected to the glass melting furnace are respectively connected to the high-temperature evaporator, and then connected to the steam drum through the rising pipe. On the other side, there are valves in the riser and downcomer on both sides of the high-temperature evaporator. When the flue gas volume and flue gas temperature of the glass melting furnace meet the design parameters, the valves are kept open to make the vertical waste heat boiler operate in a conventional manner. Operation; when the flue gas volume and flue gas temperature are far lower than the design parameters, close the riser and downcomer valves, so that the high-temperature evaporator is in an anhydrous and no-steam state. At this time, the high-temperature evaporator does not cool down the flue gas and does not participate in the hydrodynamic force of the vertical waste heat boiler, which can ensure the stable water level and normal operation of the vertical waste heat boiler. The invention has the following advantages: the boiler water level can be guaranteed to be stable, and the system stability is good. It can solve the problem of insufficient boiler water power, and there will be no boiler water shortage or overwater, and the boiler operates normally and safely.
