Abstract
The residual heat using device of boiler exhaust gas, the boiler exhaust gas is drawn after taking over connection with tail gas from boiler, and it is connected to the cloth-sack-type dust removal equipment of peripheral hardware, the tail gas is serially connected with a shell-and-tube hot water heat exchanger in taking over, the shell side both ends of the shell-and-tube hot water heat exchanger are taken over respectively by the tail gas described in flanged joint, and the both ends of tube side connect water inlet pipe and outlet pipe respectively；The tube side of the shell-and-tube hot water heat exchanger is coiled in shell side, and the outlet pipe of the connection tube side connects the Water collecting tube or collecting-tank of a peripheral hardware, and float switch is provided in the Water collecting tube or collecting-tank and the avris of Water collecting tube or collecting-tank is provided with overflow pipe；It has it is simple in structure, it is easy to use and reliable, can carry out effective recycling of heat, exhaust temperature be reduced, the features such as being conducive to protect follow-up dust-extraction unit normal operation.
Description
Technical field
The utility model relates to a kind of residual heat using devices of boiler exhaust gas, belong to technical field of waste heat utilization.
Background technology
Boiler it is usually used be coal-burning boiler, but being increasingly enhanced with haze weather, government keeps under strict control coal-burning boiler
Use, it is either coal-fired to meet the steam supply needed for production thus at present mostly using combustion gas or oil burning boiler,
Or combustion gas either oil burning boiler, all there is the exhaust emissions of high heat, this exhaust emissions tend not to it is in line, but
It needs to carry out arranging outside again after being dusted device, due to tail gas, out temperature is very high from boiler, removes to what is later connected
Dirt device, if cloth-sack-type dust removal device has certain damage, so, no matter removed from energy-efficient angle or from follow-up protection
The angle of dirt device is set out, and is required for lowering the temperature of tail gas.
Invention content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of simple in structure, user
It can lean on, effective recycling of heat can be carried out, reduce exhaust temperature, be conducive to protect the boiler of follow-up dust-extraction unit normal operation
The residual heat using device of tail gas.
The purpose of this utility model is completed by following technical solution, a kind of UTILIZATION OF VESIDUAL HEAT IN dress of boiler exhaust gas
It puts, the boiler exhaust gas is drawn, and be connected to the cloth-sack-type dust removal equipment of peripheral hardware after taking over connection with tail gas from boiler, described
Tail gas take in be serially connected with a shell-and-tube hot water heat exchanger, the shell side both ends of the shell-and-tube hot water heat exchanger pass through flange respectively
The connection tail gas is taken over, and the both ends of tube side connect water inlet pipe and outlet pipe respectively.
As preferred：The tube side of the shell-and-tube hot water heat exchanger is coiled in shell side, the outlet pipe of the connection tube side
The Water collecting tube or collecting-tank of a peripheral hardware are connected, float switch is provided in the Water collecting tube or collecting-tank and in Water collecting tube or collection
The avris in pond is provided with overflow pipe.
The utility model belongs to improvements over the prior art, it have it is simple in structure, it is easy to use and reliable, heat can be carried out
Effective recycling, reduce exhaust temperature, the features such as being conducive to protect follow-up dust-extraction unit normal operation.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1, a kind of pot described in the utility model
The residual heat using device of furnace exhaust gas, the boiler exhaust gas are drawn, and be connected to peripheral hardware after 2 connection of tail gas take over of boiler 1
Cloth-sack-type dust removal equipment 3, be serially connected with a shell-and-tube hot water heat exchanger 4 in the tail gas take over 2, shell-and-tube hot water heat exchange
The shell side both ends of device 4 connect the tail gas take over 2 by flange 5 respectively, and the both ends of tube side connect water inlet pipe 6 and water outlet respectively
Pipe 7.
Shown in figure, the tube side of the shell-and-tube hot water heat exchanger 4 is coiled in shell side, the outlet pipe of the connection tube side
The Water collecting tube 8 or collecting-tank of 7 one peripheral hardwares of connection, are provided with float switch 9 and/or are being catchmented in the Water collecting tube 8 or collecting-tank
The avris of cylinder or collecting-tank is provided with overflow pipe 10.The Water collecting tube 8 or collecting-tank mainly for the production of or workshop life
Use water.
