Plasterboard integrated hot-blast stove central heating system

Abstract

The invention discloses a plasterboard integrated hot-blast stove central heating system. The system comprises a building plaster calcinator (1), an industrial byproduct plaster drier (2), a plasterboard drier (13), a hot-blast stove (3), a material receiver (5), a main induced draft fan (6) and a waste gas chimney (7). On basis of a heat supply system, the plasterboard integrated hot-blast stove central heating system refluxes part of high temperature flue gas discharged from the waste gas chimney for plaster powder production and a supplement heat source for the hot-blast stove, and at the same time, can treat dust in the high temperature flue gas. The waste heat of moisture-discharging steam produced by the plasterboard drying is reused for a heat exchanger of the hot-blast stove, so that an initial temperature of intake air of the heat exchanger is increased. The above measures complete refluxing use of the waste heat of the high temperature flue gas and reuse of the plasterboard moisture-discharging steam, thereby reducing energy consumption during the whole production process, realizing gradient utilization of heat energy, increasing utilization rate of the heat energy, greatly reducing production cost, reducing pollution of flue gas discharge to the environment and realizing energy conservation and emission reduction of the plasterboard production line.

Description

Technical field [0001] The invention relates to the technical field of heat supply that uses a hot blast stove as a heat source and utilizes industrial by-product gypsum for gypsum board production, in particular to a gypsum board integrated hot blast stove central heating system. Background technique [0002] The heating system for gypsum board production is divided into gypsum powder calcination and gypsum board drying. The general production technology is that two hot blast stoves provide heat separately, such as one hot blast stove for drying and heating of gypsum board, and another hot blast stove for heating. Industrial gypsum drying and calcining heat supply, and the steam and flue gas emitted during production are directly discharged. The overall heating system is not convenient for compact layout, waste heat cannot be used in cascades, and the system has high energy consumption and low thermal efficiency. Summary of the invention [0003] In order to solve the above exi...
