Abstract
The utility model provides a novel economizer device which overcomes the respective defects of the prior cast iron economizer and the prior steel pipe economizer and integrates the advantages of the cast iron economizer and the steel pipe economizer into a whole. The thick-wall large seamless boiler steel pipe is used as a main pipe, thin steel plate fins are welded on the main pipe to form the economizer pipes which are arranged in a matrix, the economizer pipes are welded and connected by elbows, no flange is arranged between the pipes, and the side supporting plates are arranged in a boiler flue.
Description
Economizer is to utilize the waste heat of boiler smoke to come the heat exchanger of heated feed water, belong to the boiler technology field, economizer is installed in the boiler flue, when economizer is flowed through in boiler feedwater, absorb the heat of high-temperature flue gas, feed temperature raises, make water in the evaporating heating surface of boiler, can reduce caloric receptivity, thereby reduce the boiler fired coal consumption, simultaneously because the heating tasks of water has partly been finished by economizer, cause the task of water-cooling wall and convection bank to be alleviated, thereby under the identical condition of Boiler Steam output, the economizer that serviceability is good, can reduce evaporating heating surface, save and manufacture boiler evaporating heating surface such as water-cooling wall, used steel such as convection bank.
Books and periodicals, data according to domestic existing various relevant boilers are contained, and domestic boiler generally adopts cast iron gilled tube economizer and snakelike light pipe formula steel tube economizer.They have pluses and minuses separately.
Cast iron gilled tube economizer is non-boiling formula economizer, cylinder iron makes, and is connected with cast-iron bend with flange between pipe, and its advantage is: wear-resistant stronger with corrosion resistance; Shortcoming is: compressive resistance is low, can not bear water slug, easily leaks, easily stifled ash, and maintenance capacity is big, and the thermal efficiency is low.
Coiled pipe steel pipe type economizer is to make with steel pipe, and its advantage is: can bear high pressure, not be afraid of water slug, be difficult for stifled ash, shortcoming is: coiled pipe inside is difficult to clean, wearability and corrosion-resistant, and higher to water quality requirement, cost is higher.
More than visible " boiler administrative skill ", " small-sized heat power plant boiler equipment and operation " books such as (publication of hydraulic and electric engineering publishing house).
The purpose of this utility model is that a kind of wear-resisting, corrosion-resistant, anti-water slug, withstand voltage will be provided, and, nothing low to water quality requirement leaked, and saves the high-quality steel; The economizer that volume is little, endotherm area is big, the UTILIZATION OF VESIDUAL HEAT IN coefficient is high.
Task of the present utility model is finished as follows: at first adopt the big nothing of heavy wall to meet the boiler steel steel pipe to do female pipe, tailor fin with the carbon steel sheet metal, female pipe is matrix and arranges, constitute the economizer tube by welding between fin and female pipe, each does gripper shoe with a steel plate two ends, economizer tube, is weldingly connected by elbow between tube and tube.Nowhere flange connects every group of economizer, thereby has stopped the leakage source point, and new material--heavy wall heavy caliber boiler steel seamless steel pipe is done female pipe can reach wear-resistant, corrosion-resistant owing to adopt, and improves compressive resistance, is not afraid of the purpose of water slug.And inside easy cleaning than coiled pipe, female pipe is gone up welding steel system fin, can increase heating surface area, invar is than the heat transfer coefficient height of cast iron again, so the thermal efficiency also improves greatly than cast iron gilled tube economizer, compare with snakelike light pipe steel pipe type economizer, because the boiler steel steel pipe is lower than common seamless steel pipe to water quality requirement, so can reduce requirements in water quality.Wear-resistant more corrosion-resistant than common steel tube again.Installing fin additional both can increase heating surface, can save again and do female effective high-quality steel, can reduce cost.
Further describe in conjunction with the accompanying drawings with regard to its structure composition below, its structure is installed and is seen accompanying drawing.
Figure (one) is a structural representation
Figure (two) is that the economizer tube is along the axis half-sectional view
Figure (three) is fin shapes figure
Figure (four) is integral installation figure
The meaning of numbering representative is in the accompanying drawing:
(1) female pipe, (2) fin, (3) connecting bend, (4) side gripper shoe, (5) fin and female pipe solder side, (6) gripper shoe and economizer tube solder side, (7) connecting bend and economizer tube solder side, (8) boiler flue wall, (9) flue, (10) economizer inlet valve, (11) economizer flowing water Valve.
Make with reference to the female effective boiler steel seamless steel pipe in figure (one) (1), (2) fin is tailored into a rectangle or the b circle of figure (three) with sheet metal, punch according to female external diameter of pipe in the center, referring to figure (two) fin is evenly worn at interval and to be gone on foot on female pipe, welding forms solder side (5) between fin and female pipe, so make many economizer tube, punch respectively with two blocks of steel plates again and make gripper shoe (4), penetrate from two ends and to support the economizer tube, note to make the economizer tube to arrange into battle array during punching, welding forms solder side (6) between side gripper shoe and female pipe, connecting bend (3) also forms with the boiler steel steel tube bending, the mother's pipe that the side gripper shoe outside is stretched out with connecting bend welds one by one, reserve the Inlet and outlet water mouth of pipe, make the economizer tube formation one of all installations be the water stream channel that matrix is arranged, after the water pressure test, can pack in the flue (9), be arranged in the boiler flue by side gripper shoe (4) with reference to figure (four), seal in the feed water system of boiler through inlet valve (10) flowing water Valve (11), can put into operation.
Through trial run, economizer leakage and bombing accident did not take place, and improved the thermal efficiency, through on SHL20～25/400 type boiler, surveying, the more former cylinder iron economizer of matrix fin type steel tube economizer is imported and exported water-feeding difference and is brought up to 78 ℃ by 36 ℃, and the economizer maintenance capacity reduces greatly.
The utility model--matrix finned steel tube coal saving, owing to adopted new material and new technology, concentrate the advantage of existing cast iron gilled tube economizer and steel tube economizer, overcome separately disadvantage, both wear-resistant corrosion-resistant, withstand voltage, can bear water slug again, the used high-quality steel of steel tube economizer processed are saved again in not water funk boiling, and cost is low and volume is little, endotherm area is big, fume afterheat usage factor height, the boiler for adopting cast iron gilled tube economizer can not change its former design overall dimensions, directly substitute cast iron gilled tube economizer, reach stable, better energy-saving and cost-reducing, the purpose of material-saving.
