Abstract
The utility model discloses a steam and waste heat converting boiler. The steam and waste heat converting boiler comprises a boiler main body and a steam pocket, wherein ascending tubes and descending tubes are connected between the boiler main body and the steam pocket; heat exchange tubes are mounted in the boiler main body; a plurality of supporting plates are arranged in the boiler main body in the radial direction; holes corresponding to the heat exchange tubes are formed in the supporting plates. Each of the heat exchange tubes is supported in single holes of the supporting plates to avoid the contact of the heat exchange tubes after the heat exchange tubes are collapsed, so that the effect of preventing internal tubes from being cracked is acted. Impingement plates are individually arranged in each port of the descending tubes; a man hole is formed in a tube box at the front end of the outer side of the boiler main body. The steam and waste heat converting boiler can prevent the damage of the heat exchange tubes and the tension fracture of joints, so that the normal operation of equipment is guaranteed, the productivity is improved, the service life of the equipment is effectively ensured, and the service life of an accommodator is prolonged.
Description
Technical field
The utility model relates to boiler, particularly at Coal Chemical Industry, fertilizer enterprises, is arranged on a kind of conversion vapour waste heat boiler on conversion section.
Background technology
Transforming vapour waste heat boiler is mainly comprised of waste heat boiler body, drum and tedge and down-comer.Waste heat boiler body is an evaporation and heat-exchange equipment, and thermal source is pyroprocess gas, and heated medium is for approaching saturated boiler water; Drum should have enough vapor volumes and water capacity; Main Function is to make heat exchanger tube in body under thermic load effect, can continue to obtain the suitable water yield; and obtain certain circulation power by high-order system and the carbonated drink density contrast of drum, to meet the requirements of water circulation reliability; Inside steam drum arranges water separator, makes steam water interface fully separated in drum, obtains steam moisture and that impurity is few; Boiler feedwater is heated to saturated before entering waste heat boiler body in drum, has improved circulation power; Saturated boiler water flows into waste heat boiler body through down-comer and carries out heating evaporation, and the steam water interface in body flows into drum through tedge, and so circulation reaches the safe operation of Waste Heat System.
1), the baffle arrangement design that arranges of the decline mouth of pipe is unreasonable there is following problem in former waste heat boiler equipment project organization:, a plurality of decline mouths of pipe only arrange a baffle plate, cause carbonated drink contact uneven, excessive temperature differentials, the variation contraction inequality of heat exchanger tube because expanding with heat and contract with cold, cause heat exchanger tube and pipe sheet weld joint drawing crack, cause leakage; 2), equipment in running, along with the variation of expanding with heat and contract with cold, cause heat exchanger tube to subside, tube and tube is in contact with one another, between pipe, gapless does not have the effect of heat exchange, tube wall temperature is too high, causes inner tube to split; 3) body of heater outside is provided with front-end pipe box, but manhole is not set on front-end pipe box, is unfavorable for the inspection and maintenance of tube head in front-end pipe box.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of conversion vapour waste heat boiler, and this boiler can overcome the defect that the inner tube that exists in prior art is split.
For solving the problems of the technologies described above, the utility model has been done further improvement on the basis of existing technology.
The technical solution adopted in the utility model is: a kind of conversion vapour waste heat boiler, comprise boiler body and drum, between boiler body and drum, be connected with tedge and down-comer, heat exchanger tube is housed in boiler body, several gripper shoes are axially set in boiler body, in gripper shoe, have the hole corresponding with heat exchanger tube.
Each heat exchanger tube is supported in hole independent in gripper shoe, can avoid heat exchanger tube to subside after contact between tube and tube, thereby play the effect that prevents that inner tube from splitting.
As a kind of preferred technical scheme, at each decline mouth of pipe place, impingement baffle is set separately.
Further, the cross section that described impingement baffle is set is arc, and this arc section is 30 ° in the central angle corresponding to boiler body center.
As the preferred technical scheme of another kind, on the front-end pipe box in boiler body outside, manhole is set.
Compared with prior art, the utility model improves transforming the structure of vapour waste heat boiler, prevent that heat exchanger tube from damaging and joint drawing crack, can guarantee that equipment normally moves, anti-fatigue performance is good, has improved production efficiency, reaches energy-saving and cost-reducing effect, the life cycle of effective assurance equipment, the use working life that extends container.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
In figure, 1-boiler body, 2-drum, 3-tedge, 4-down-comer, 5-heat exchanger tube, 6-gripper shoe, 7-impingement baffle, 8-front-end pipe box, 9-manhole.
The specific embodiment
As shown in Figure 1, a kind of conversion vapour waste heat boiler described in the utility model, comprise boiler body 1 and drum 2, between boiler body 1 and drum 2, be connected with tedge 3 and down-comer 4, heat exchanger tube 5 is housed in boiler body 1, in interior several gripper shoes 6 that axially arranges of boiler body 1, in gripper shoe 6, have the hole corresponding with heat exchanger tube 5.
Generally, can be only fix two gripper shoes 6 boiler body 1 is interior, gripper shoe 6 is fixed on boiler height direction, in gripper shoe 6, have some holes, the aperture in these holes is corresponding with aperture and the position of heat exchanger tube 5 on boiler body 1 with position, when gripper shoe 6 be installed on boiler body 1 interior after, all heat exchanger tubes 5 can be supported in hole.Avoid heat exchanger tube 5 in running, because the variation of expanding with heat and contract with cold produces excessive amount of deflection, affect the heat-transfer effect between pipe.
As shown in Figure 1 and Figure 2, at each down-comer, 4 mouthfuls of places arrange separately impingement baffle 7, use independently impingement baffle 7 can make carbonated drink contact evenly, have reduced the temperature difference, the variation of heat exchanger tube 5 is shunk evenly, thereby avoids the leakage that causes due to heat exchanger tube 5 and pipe sheet weld joint drawing crack.
As shown in Figure 2, the cross section of described impingement baffle 7 is arc, and this arc section is 30 ° in the central angle a corresponding to boiler body 1 center.Before improving, impingement baffle 7 is 45 ° with the central angle at boiler body 1 center, and the utility model has reduced this central angle, and the width of impingement baffle 7 is diminished, and is conducive to carbonated drink even contact.
As shown in Figure 1, on the front-end pipe box 8 in boiler body 1 outside, manhole 9 is set, facilitates the inspection and maintenance of front-end pipe box 8 interior tube heads.
