Abstract
The utility model discloses a boiler flue-gas device for waste-heat utilization of a lime kiln. The boiler flue-gas device comprises an inlet flue, a boiler tube box and an outlet flue, wherein the inlet flue is connected with one end of the boiler tube box, the other end of the boiler tube box is connected with the outlet flue, heat-preservation layers are installed on the inner side of the inlet flue and the inner side of the boiler tube box, reinforcement ribs are installed on the outer side of the inlet flue and the outer side of the boiler tube box, and an external heat-preservation structure is adopted for the outlet flue. Besides, an ash falling bucket is installed at the turning position of the outlet flue, and the ash falling bucket is of a funnel-shaped structure. The boiler flue-gas device makes comprehensive use of waste-heat resources discharged by a lime production line, lowers production cost, protects the environment, and promotes economic benefits of enterprises.
Description
Technical field
The utility model relates to a kind of boiler smoke device, in particular, relates to the boiler smoke device in the UTILIZATION OF VESIDUAL HEAT IN of a kind of limekiln.
Background technology
In the production process in limekiln, the Gas Parameters that produces is: 320 ℃～450 ℃ of flue collector flue-gas temperatures, average every flue gas flow is 140,000 m3/h, a large amount of high-temperature flue gas of association in the lime production process, can only drain into by the laggard electric precipitation of cooled exhaust gas temperature and diffuse chimney and diffuse, cause the wasting of resources.Successful example according to principle and the industry of energy-conserving and environment-protective, by the waste heat boiler power plant is set up in flue gas waste heat recovery simultaneously, generating exhaust temperature later descends, met the requirement of advancing sack cleaner (sack cleaner inlet temperature≤180 ℃), thereby not only heat energy is converted into electric energy, improve energy utilization rate, and saved the energy that is used for the cooled exhaust gas temperature.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of raising using energy source is provided, and reduces the boiler smoke device in the limekiln UTILIZATION OF VESIDUAL HEAT IN of environmental pollution.
In order to solve above technical problem, the utility model provides the boiler smoke device in the UTILIZATION OF VESIDUAL HEAT IN of a kind of limekiln, it is characterized in that, comprise gas approach, boiler bobbin carriage and exhaust pass, described gas approach is connected with described boiler bobbin carriage one end, the described boiler bobbin carriage other end is connected with described exhaust pass, and the inboard of described gas approach and described boiler bobbin carriage arranges heat-insulation layer, the arranged outside reinforcement; Described exhaust pass adopts the external insulation structure, and, at the turning point of described exhaust pass ash dropping hopper being set, described ash dropping hopper is funnel-shaped structure.
The technical scheme that the utility model further limits is that the outer reinforcement that arranges of described gas approach and described boiler bobbin carriage is one deck steel plate.
Further, welding is fixing between described boiler bobbin carriage and described gas approach and the described exhaust pass.
Further, the external insulation structural outer of described exhaust pass arranges one deck color steel.
Further, also comprise flapper, described flapper is arranged at the cinder-discharging port of described ash dropping hopper.
Further, described flapper top arranges 2 unloading valves.
The beneficial effects of the utility model are: the boiler smoke device in the UTILIZATION OF VESIDUAL HEAT IN of a kind of limekiln described in the utility model, comprehensive utilization lime production line waste heat resource reduces production costs, protection environment, raising business economic benefit.
Description of drawings
Fig. 1 is the structured flowchart of the boiler smoke device in the UTILIZATION OF VESIDUAL HEAT IN of a kind of limekiln described in the utility model.
The specific embodiment
Embodiment 1
Boiler smoke device in a kind of limekiln UTILIZATION OF VESIDUAL HEAT IN that present embodiment provides, its structural representation as shown in Figure 1, comprise gas approach 1, boiler bobbin carriage 2 and exhaust pass 3, described gas approach 1 is connected with described boiler bobbin carriage 2 one ends, and described boiler bobbin carriage 2 other ends are connected with described exhaust pass 3.Welding is fixing between described boiler bobbin carriage 2 and described gas approach 1 and the described exhaust pass.
The inboard of described gas approach 1 and described boiler bobbin carriage 2 arranges heat-insulation layer, and arranged outside reinforcement, described reinforcement are one deck steel plate.
Described exhaust pass 3 adopts the external insulation structure, and the external insulation structural outer arranges one deck color steel.And, at the turning point of described exhaust pass ash dropping hopper 4 being set, described ash dropping hopper 4 is funnel-shaped structure, the cinder-discharging port place of ash dropping hopper 4 arranges a flapper, and the flapper top arranges 2 unloading valves, when avoiding putting ash, a large amount of cold airs enter boiler, increase the load of air-introduced machine.Collecting ash adopts automobile to transport, and carries out the single step of releasing ash during operation approximately weekly.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
