Abstract

The invention discloses a boiler flue gas cooler and belongs to the technical field of cooling equipment. The cooler comprises a cooler body provided with a flue gas inlet and a flue gas outlet. The side wall of the cooler body comprises an outer layer and an inner layer. A transverse heat-absorbing tube stack is arranged between the outer layer and the inner layer. A plurality of vertical heat-absorbing tube stacks enabling flue gas to flow in a turn-back mode in the cooler body is arranged in the cooler body. Inlets and outlets of the vertical heat-absorbing tube stacks are communicated with the transverse heat-absorbing tube stack. A water inlet of the transverse heat-absorbing tube stack is communicated with a steam water outlet of the transverse heat-absorbing tube stack through a pump and a steam separator. The problems that an existing electric fan cooling method is low in cooling speed, large in electric energy consumption and high in cost, and a water spraying method wastes water resources can be solved.

Description

Boiler smoke cooler
Technical field
The present invention relates to boiler plant technical field, especially a kind of device for boiler smoke cooling.
Background technology
Boiler is the heat energy utilizing fuel or other energy, water or dielectric heating, export the plant equipment that heat energy supplies people's production and living needs, the flue gas that its fuel combustion produces is directly emitted by chimney, the flue gas dust concentration of not only discharging is high, flue gas blackness is large, also severe contamination is caused to environment, therefore input in clean room again after needing that the flue gas that band has surplus heat is cooled to normal temperature and process, what existing falling temperature method adopted is by electric fan to be exchanged with cold air to lower the temperature and to be sprayed flue by water to hot-air around flue and lowers the temperature, it is slow that these two kinds of methods also exist electric fan falling temperature method cooling rate, consume the problem that the high and Water spray method of a large amount of cost of electric energy causes the waste of water resource.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of boiler smoke cooler, and this cooler can solve existing electric fan falling temperature method cooling rate, and to consume a large amount of cost of electric energy slowly high, and Water spray method causes the problem of the waste of water resource.
In order to solve the problem, the technical solution adopted in the present invention is: this boiler smoke cooler, comprise the cooler body offering gas approach and exhanst gas outlet, described cooler body sidewall includes skin and internal layer, horizontal endothermic tube group is provided with between described skin and internal layer, be provided with in described cooler body make flue gas turn back in described cooler body flowing multiple vertical endothermic tube group, the import of described vertical endothermic tube group is all connected with described horizontal endothermic tube group with outlet, the water inlet of described horizontal endothermic tube group is connected with carbonated drink export of steam-water separator with described horizontal endothermic tube group by being arranged at this external pump of described cooler.
In technique scheme, technical scheme can also be more specifically: the cold medium in described horizontal endothermic tube group and vertical endothermic tube group is water, and described horizontal endothermic tube group and vertical endothermic tube group are regularly arranged and the multiple U-tube communicated of connecting.
Further: steam-water separator to offer carbonated drink import, water inlet, venthole, delivery port, described carbonated drink import is connected with the carbonated drink outlet of described horizontal endothermic tube group, and described delivery port is connected with the water inlet of described pump.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, due to be provided with in cooler body wall body in horizontal endothermic tube group and cooler body be provided with make flue gas turn back in cooler body flowing multiple vertical endothermic tube group, heat in high-temperature flue gas is effectively absorbed cooling by ducted water, and water changes the mixture of steam and water into and flows out recycling, while having saved the energy, reach the object of cooled flue gas.
2, owing to being provided with steam-water separator, steam and water export by steam-water separator respectively, and steam is used effectively, and water again enter horizontal endothermic tube group carry out heat absorption circulation, saved water resource.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Boiler smoke cooler shown in Fig. 1, comprise the cooler body 1 offering gas approach 1a and exhanst gas outlet 1b, cooler body 1 sidewall includes outer 11 and internal layer 12, horizontal endothermic tube group 2 is provided with between outer 11 and internal layer 12, be provided with in cooler body 1 make flue gas turn back in cooler body 1 flowing multiple vertical endothermic tube group 21, cold medium in horizontal endothermic tube group 2 and vertical endothermic tube group 21 is water, horizontal endothermic tube group 2 and vertical endothermic tube group 21 are regularly arranged and the multiple U-tube communicated of connecting, the import of vertical endothermic tube group 21 is all connected with horizontal endothermic tube group 2 with outlet, horizontal endothermic tube group 2 connects a steam-water separator 4 by pump 5, steam-water separator 4 offers carbonated drink import 4a respectively, water inlet 4d, venthole 4b, delivery port 4c, the water inlet of horizontal endothermic tube group 2 is connected with the delivery port of pump 5 by the collector pipe 6 be arranged at outside cooler body 1, the water inlet of pump 5 is connected with the delivery port 4c of steam-water separator 4, carbonated drink import 4a is connected with the carbonated drink outlet of horizontal endothermic tube group 2 by the collector pipe 7 be arranged at outside cooler body 1, delivery port 4c is connected with the water inlet of pump 5.
During work, flue gas turns back flowing in cooler body, heat in high-temperature flue gas is effectively absorbed cooling by ducted water, and water changes the mixture of steam and water into and arrives steam-water separator after flowing out, steam and water export by steam-water separator respectively, steam is used effectively, and water again enter horizontal endothermic tube group carry out heat absorption circulation, saved water resource.
