Background technology
Common Industrial Boiler flue gas just directly is discharged into atmosphere through dust arrester without UTILIZATION OF VESIDUAL HEAT IN and desulfurization processing, causes a large amount of energy wastes, and contaminated environment, is unfavorable for environmental protection.In order to reduce the waste of the energy, heated surface at the end of boiler is provided with economizer.But because economizer is normal temperature feedwater, minimum wall temperature is more near feed temperature, though the Industrial Boiler back-end surfaces under higher exhaust gas temperature as 160 ℃ or higher, still there is cold end corrosion and all can phenomenon in economizer, influences the normal operation of boiler.Therefore, at present, some boiler design exhaust gas temperature reaches 200 ℃, even higher, causes a large amount of energy wastes.Existing Industrial Boiler economizer adopts cast iron gilled tube economizer usually, and its structure is heavy, consumes a large amount of ferrous materials, though corrosion resistance is stronger, it is owing to the clogging phenomenon that dewfall causes can't effectively be solved.
The utility model content
The purpose of the utility model is to utilize insufficient or flue gas causes stifled ash of burn into and problem of environment pollution caused to economizer to existing Industrial Boiler fume afterheat, and a kind of industry boiler energy-conservation environmental protection integrated device that makes full use of fume afterheat, good dedusting effect and energy-conserving and environment-protective is provided.
The technical scheme of the utility model is: a kind of industry boiler energy-conservation environmental protection integrated device; Comprise flue gas waste heat recovery apparatus and dust arrester; Described flue gas waste heat recovery apparatus comprises the heat-exchanger rig that water storage tank is inner with being arranged on water storage tank; Described heat-exchanger rig comprises heating module and is sleeved on the heat pipe on the heating module that heating module and flue are connected; Described dust arrester comprises dust cleaning case, and dust cleaning case and heating module are connected, and is provided with spray equipment and flue dust part flow arrangement in the dust cleaning case;
Preferably, the top of described water storage tank is provided with a water inlet and a steam (vapor) outlet, and the side is provided with a water level meter, a delivery port and a chimney intake, and the bottom of water storage tank also is provided with a sewage draining exit;
Preferably, described heating module is provided with two, and the air inlet of two heating modules merges the back and is connected with flue, and the gas outlet merges the back and is connected with dust cleaning case, and is respectively installed with one group of heat pipe on each heating module;
Preferably, described spray equipment comprises spray water pump and spray thrower, and spray thrower is arranged on dust cleaning case and heating module junction;
Preferably, described flue dust part flow arrangement is multistage flue dust flow distribution plate;
Preferably, described flue dust flow distribution plate is set to two-stage;
Preferably, the top of described dust cleaning case is provided with a cleaning door, an inspection socket and a flue outlet, and the bottom is provided with a sewage draining exit.
The beneficial effect of the utility model is: the utility model is rational in infrastructure, energy-conserving and environment-protective.At first directly the waste heat that flue gas is taken out of in the boiler is recycled, improved rate of energy through flue gas waste heat recovery apparatus; And need not add economizer, save a large amount of ferrous materials at boiler tail.Simultaneously; The utility model separates the dust that exists in the flue gas through dust arrester, utilizes spray thrower earlier flue gas to be sprayed, and flue gas is carried out desulfurization and dedusting handle; And then separate through the flue dust flow distribution plate; The dust of separating drops in the dust cleaning case, removes the dust in the dust cleaning case through cleaning door, has solved the problem of smoke pollution environment with stifled ash effectively.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
The practical implementation of the utility model: as shown in Figure 1; A kind of industry boiler energy-conservation environmental protection integrated device; Comprise flue gas waste heat recovery apparatus and dust arrester, described flue gas waste heat recovery apparatus comprises water storage tank 1 and the heat-exchanger rig that is arranged on water storage tank 1 inside, and the top of water storage tank 5 is provided with a water inlet 6 and a steam (vapor) outlet 7; The side is provided with a water level meter 8, a delivery port 9 and a chimney intake 10, and the bottom of water storage tank 1 also is provided with a sewage draining exit 11; Dust arrester comprises dust cleaning case 5, is provided with spray equipment and flue dust part flow arrangement in the dust cleaning case 5, and the top of dust cleaning case 5 is provided with a cleaning door 15, an inspection socket 16 and a flue outlet 17, and the bottom is provided with a sewage draining exit 18.Heat-exchanger rig comprises heating module 2 and is sleeved on the heat pipe 3 on the heating module 2; Heating module 2 is provided with two; The air inlet of two heating modules merges the back and is connected with flue 4; The gas outlet merges the back and is connected with dust cleaning case 5, and is respectively installed with one group of heat pipe on each heating module.Spray equipment comprises spray water pump 12 and spray thrower 13, and spray thrower 13 is arranged on dust cleaning case 5 and heating module 2 junctions; The flue dust part flow arrangement is a two-stage flue dust flow distribution plate 14.
