The boiler of prior art, especially for the boiler to community user heat supply, when northern winter, temperature was relatively low, the viscosity of fuel is generally relatively larger, efficiency of combustion is relatively low, and the cold water heated is from subsoil water, temperature is relatively low, inefficient, heat supply is slower, and the flue gas that northern most of boiler combustion is emerged essentially directly discharges, there is no recycling, the serious heat energy wasted in flue gas.
Summary of the invention
It is an object of the invention to provide a kind of preheating device of boiler water, utilize the heat energy in boiler smoke that cold water is preheated, be both easy to boiler combustion time fuel saving, improve the efficiency of heating surface, take full advantage of again substantial amounts of heat energy in flue gas.
The purpose of the present invention is achieved through the following technical solutions:
A kind of preheating device of boiler water, including preheating cylinder, bracing frame, ash inlet tube, dust collecting bin, described preheating cylinder is supported on the ground by bottom bracing frame, and described preheating cylinder bottom connects dust collecting bin by ash inlet tube；Described preheating cylinder left upper end device air inlet pipe, upper right side device escape pipe；Described preheating cylinder left upper end, air inlet pipe device for upper end normal-temperature water water inlet pipe, preheat cylinder bottom righthand side device preheating water drain pipe；Described preheating cylinder interior arrangement heat exchanger tube, gas block panel.
Described heat exchanger tube is made up of multiple " time " type bend pipe, and the described heat exchanger tube upper end mouth of pipe connects normal-temperature water water inlet pipe, and the described heat exchanger tube lower end mouth of pipe connects preheating water drain pipe.
Described gas block panel is stainless steel metal baffle plate, and described gas block panel upper end is fixed on preheating cylinder end face, and described gas block panel lower end is fixed on preheating water drain pipe.
Device water discharging valve on described preheating water drain pipe.
Described preheating cylinder bottom is the back taper body without conehead.
The corrosion-resistant insulation inner shell of device on described preheating cylinder inwall.
Described corrosion-resistant insulation inner shell is the corrosion-resistant insulation inner shell of polyurethane.
A kind of preheating device of boiler water of the present invention, in use, first normal-temperature water is injected into heat exchanger tube from normal-temperature water water inlet pipe, then the flue gas that boiler combustion produces is connected air inlet pipe by pipeline, make it into preheating cylinder, for the normal-temperature water heat exchange in heat exchanger tube, after heat exchange, flue gas is discharged, and the water after preheating is discharged by preheating water drain pipe；After flue gas enters preheating cylinder, will being discharged by escape pipe, it is necessary to by the stop of gas block panel, in stop process, bulky grain dust or impurity in flue gas can be fallen by gear, entered in dust collecting bin by ash inlet tube.
Beneficial effects of the present invention: a kind of preheating device of boiler water of the present invention, utilizes the heat energy in boiler smoke that cold water is preheated, and has both been easy to boiler combustion time fuel saving, improves the efficiency of heating surface, takes full advantage of again substantial amounts of heat energy in flue gas；And arranging one piece of gas block panel inside the present invention, the flue gas entering preheating cylinder all can be blocked for a moment so that bulky grain dust or impurity whereabouts, collect to dust collecting bin, be effectively reduced air pollution, protect environment.
