The utility model enables fuels having different sulfur contents to approach to the acid dew point of the flue gas after the flue gas enters a desulfuration system through controlling the exhausted gas temperature of the flue gas, so that the desulfuration efficiency is raised, and the effects of energy-saving and dust removing are integrated.
Description
The utility model relates to deduster, particularly a kind of heat pipe heat exchanging temperature control deduster.
Desulfurization and dedusting facility of the prior art owing to can not control flue-gas temperature, is difficult to make flue gas to make S/Ca=1 carry out desulfurization near acid dew point the time at grasp flue gas under the situation of different sulfur content, its flue gas desulfurization effect instability.
Though existing boiler economizer can absorb waste heat, belong to discontinuity work, can not stablize the flue gas exhaust gas temperature.
On deduster, use heat pipe at present and do waste heat recovery, only consider the waste heat recovery rate, and when sulfur content was high in the flue gas, flue gas acid dew point improved also, cause the corrosion of deduster internal acid to increase the weight of easily.
The purpose of this utility model is: a kind of heat pipe heat exchanging temperature control deduster is provided, it is by the control to the flue gas exhaust gas temperature, the fuel that makes different sulfur content near flue gas acid dew point, improves desulfuration efficiency when flue gas enters desulphurization system, can collect energy-conservation again, dust removing effects is integrated.
Formation of the present utility model: form by heat-exchanging water tank, heat absorption dirt pocket, cyclic water tank and circulating pump, heat-exchanging water tank (3) is installed in top at heat absorption dirt pocket (10), ash head (11) is installed in the below, there are gas approach (9) and exhanst gas outlet (8) in the both sides of heat absorption dirt pocket (10), and there is the light pipe heat pipe (12) and the gas baffle (14) (15) of cross arrangement inside; Water inlet pipe (1) and outlet pipe (6) are arranged on the heat-exchanging water tank (3), be connected with cyclic water tank (5) with pipeline, in circulating pump (7) front valve (16) is arranged, cross arrangement fin heat pipe (13) in heat-exchanging water tank (3) by circulating pump (7).
Thermometer (2) and water level meter (4) are housed on heat-exchanging water tank (3).
The elementary dedusting of the utility model collection flue gas waste heat recovery compared with the prior art,, control exhanst gas outlet temperature and exhaust gas dust is that the collection of one is energy-conservation, the equipment of dedusting and cigarette temperature control.Have that flue gas resistance is little, good energy-conserving effect, advantage such as integration capability is strong, floor space is little, easy and simple to handle, small investment.Compare with existing miniature boiler dedusting, energy-conservation facility, following characteristics arranged:
1, collection is energy-conservation, control exhaust gas temperature, dedusting is integrated, has reduced floor space, for desulfurization provides good condition.
2, because the dirt pocket heat pipe is a light pipe, be not with fin, its flue gas resistance is little, does not hinder ash, is convenient to cleaning.
3, heat exchange adopts heat pipe with fin heat release (the heat-exchanging water tank heat pipe equals dirt pocket light pipe heat pipe endotherm area with fin heat release area), its good effect of heat exchange, (exhaust gas temperature based on fuel sulfur content is just determined according to the exhaust gas temperature needs, one exhaust gas temperature should be near flue gas acid dew point), its water temperature circulates about 60 ℃, non flouling behaviour.
4, Heat Room is non-pressure vessel, and is easy and simple to handle, and installation and maintenance are convenient.
5, after the utility model is installed on miniature boiler, can cancel economizer and dry collector.Because flue-gas temperature is effectively controlled, and can increase substantially smoke desulfurization efficiency.This equipment is installed on the patent No.: in 002235846 " miniature boiler is energy-conservation; desulfurization; dust removal integrated plant ", obtained positive effect, it is integrated energy saving cooler and low-resistance deduster, reduced floor space, controlled exhaust gas temperature effectively, boiler smoke can enter desulfurization spray wet dust collector by air-introduced machine near acid dew point the time, flue gas is formed solution-air and liquid-liquid reactions in the spray washing process, make S/Ca=1, accelerated the reaction of sulfur dioxide in flue gas and desulfurizing agent, therefore for the high fuel of sulfur content,, just can control the discharging of sulfur dioxide effectively as long as improve the basicity (pH value can reach more than 13) of desulfurizing agent.
6, use the valve regulated circulating water flow, the control exhaust gas temperature, it is simple to operate, and effect is remarkable, is convenient to grasp.
