Abstract

A high-efficiency recycling device for waste heat of boiler tail gas belongs to the technical field of environment-friendly energy-saving device and boiler accessory. The aim of the utility model is to provide the high-efficiency recycling device for waste heat of boiler tail gas, which utilizes the waste heat of boiler for obtaining the effects of energy saving and consumption reduction. The utility model is technically characterized in that the high-efficiency recycling device for waste heat of boiler tail gas comprises the boiler, a coal saver, a dust remover and a chimney. The utility model is characterized in that: a heat exchanger (6) which is composed of a built-in circular preheating water pipe and a smoke discharge passage is provided between the coal saver (4) and the dust remover (7); a water inlet (61) of the heat exchanger is connected with the cold water pipe; a water outlet of the heat exchanger is communicated with a hot water storage tank (5); and a water outlet of the hot water storage tank is communicated with a water inlet of the coal saver. The temperature of the water supplied to the boiler can be above 90 DEG C after heat absorbing and temperature increase by the heat exchanger, thereby greatly increasing the thermal efficiency, reducing energy loss of boiler and realizing the purposes of energy saving and consumption reduction.

Description

Boiler exhaust gas waste heat high efficiente callback use device
Technical field
The utility model relates to a kind of boiler exhaust gas waste heat high efficiente callback use device, belongs to environment protecting power economizer and boiler accessories technical field.
Background technology
At present, the using waste heat from tail gas when making full use of boiler exhaust gas, generally the boiler outlet flue and and deduster between economizer is set, utilize the waste heat heating boiler feedwater of boiler tail flue gas, to reach the purpose of fuel saving.Though economizer has utilized the waste heat of boiler tail flue gas, efficient is also not really high, and boiler exhaust gas is behind the process economizer, and its temperature is also very high, also has very high value, but this part energy is not owing to being fully utilized, so caused the waste of the energy.
Goal of the invention
The purpose of this utility model is to provide a kind of can utilize boiler afterheat as much as possible, reaches the boiler exhaust gas waste heat high efficiente callback use device of energy-saving and cost-reducing effect.
Its technical scheme is: a kind of boiler exhaust gas waste heat high efficiente callback use device, comprise boiler, economizer, deduster and chimney, it is characterized in that: be provided with the heat exchanger that preheating water pipe and discharge flue by built-in circulation constitute between described economizer and the deduster, the water inlet of heat exchanger is connected with cold water pipes, its delivery port is communicated with the hot water storage tank, and hot water storage tank's delivery port is communicated with the water inlet of economizer.
Be provided with water pump between above-mentioned hot water storage tank's the delivery port and the water inlet of economizer.
Its technique effect is: after boiler feedwater heats up by the heat absorption of the preheating water pipe in the heat exchanger, water temperature can be up to more than 90 ℃, thereby improved the thermal efficiency greatly, reduced the energy loss of boiler fired coal or combustion gas, fuel oil, farthest utilize the waste heat of boiler exhaust gas, realized the purpose of energy-saving consumption-reducing.The utility model is simple in structure, makes, maintenance cost is low, easy operating.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, boiler exhaust gas waste heat high efficiente callback use device comprises boiler 1, economizer 4, deduster and chimney 8.Be provided with the heat exchanger 6 that preheating water pipe and discharge flue by built-in circulation constitute between economizer and the deduster 7, the water inlet 61 of heat exchanger is connected with cold water pipes, its delivery port is communicated with hot water storage tank 5, and hot water storage tank's delivery port is communicated with the water inlet of economizer by water pump 3.
