Abstract
The utility model relates to an efficient corrosion-resistant hot-tube type coal economizer, comprising a plurality of jacket type hot tubes, a box body and two partition plates with a plurality of through holes. The two partition plates are arranged in the box body and divide the box body into a middle part and two side end parts, the plurality of jacket type hot tubes are arranged in the middle part, both ends of the inner tube of the jacket type hot tube are respectively penetrated into the two side end parts through the through holes of the two partition plates, and the ends of the inner tubes of the head and the tail jacket type hot tubes are led out from the box body in one side end part. The ends of the inner tubes of the rest jacket type hot tubes are connected every two in the side end part of each box body to form serial snake-shaped coil pipe.
Description
The present invention relates to a kind of economizer, relate in particular to a kind of heat pipe type of coal saver resisting corrosion effectively.
At present, in acid production with sulphur and city garbage burning, there are a large amount of high-temperature flue gas to produce,, reduce cost, adopt waste heat boiler to reclaim heat in these flue gases usually, and contain SO in these flue gases in order to improve the heat energy utilization rate
3, HCI, H
2Corrosive gas such as S, dew-point temperature are very high, cause waste heat boiler low-temperature zone heating surface or the serious corrosion of economizer, and equipment puts into operation to rot soon and wears.
In order to avoid taking place the corrosion of acid dew point, improve service life of equipment, number of patent application is that the 98110872.5 patent heat pipe type of coal saver resisting corrosion effectively of being applied for have adopted gravity assisted heat pipe, the temperature of the feasible housing that contacts with flue gas is improved, thereby avoid taking place the corrosion of acid dew point, improved the service life of equipment.But it still exists very big shortcoming, it owing to whole gravity assisted heat pipe the gravity assisted heat pipe system of the sealing that forms by a series of pipeline UNICOM, working medium is moved in gravity assisted heat pipe, thereby it is quite high for the welding requirements of pipeline enclosure, in case and the somewhere is because of certain reason generation seepage, whole so inevitably gravity assisted heat pipe will lose efficacy, and therefore whole equipment scrapped.
The purpose of this utility model is to provide a kind of corrosion that can avoid taking place acid dew point, improves service life of equipment, in case and the somewhere heat pipe type of coal saver resisting corrosion effectively of operation as usual that seepage does not influence whole equipment has taken place.
The purpose of this utility model is to realize like this, a kind of heat pipe type of coal saver resisting corrosion effectively, it is characterized in that, it comprises: some sleeve type heat-pipes (is 98107804.4 sleeve type heat-pipes of being applied for by number of patent application), casing and two division boards that respectively have some perforation, two division boards place in the casing and with casing and are separated into a mid portion and two limit end parts, described some sleeve type heat-pipes place mid portion, interior pipe two ports of sleeve type heat-pipe pass from the perforation of two division boards respectively and enter two limit end parts, and in a limit end parts with head, the port of pipe is drawn from casing in two sleeve type heat-pipes of tail, the inner tube mouth of remaining sleeve type heat-pipe links to each other in the limit end parts of separately casing in twos, thereby forms the serpentine coil shape of series connection.
Owing to adopted above-mentioned technical solution, not only the temperature of the feasible housing that contacts with flue gas is improved, avoid taking place the corrosion of acid dew point, the service life of raising equipment, and it provides a kind of heat pipe tube bank of being made up of single heat pipe, and UNICOM of pipe is quite ripe technically in it, and in case some outer tube generation seepages perhaps can produce certain influence to whole economizer parameter, but whole equipment still can move as usual, and heat pipe can singly prop up to change and repairs.
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
Fig. 1 is an example structure schematic diagram of the present utility model.
By shown in Figure 1, the utility model heat pipe type of coal saver resisting corrosion effectively, it comprises some sleeve type heat-pipes 3 (is 98107804.4 sleeve type heat-pipes of being applied for by number of patent application), casing 1 and two division boards 2 that respectively have some perforation, two division boards 2 place in the casing and with casing and are separated into a mid portion 11 and two limit end parts 12, described some sleeve type heat-pipes place mid portion 11, interior pipe two ports of sleeve type heat-pipe pass from the perforation of two division boards respectively and enter two limit end parts 12, and in a limit end parts 12 with head, the port 31 of pipe in two sleeve type heat-pipes of tail, 32 draw from casing 1, the inner tube mouth of remaining sleeve type heat-pipe links to each other in the limit end parts 12 of separately casing in twos, thereby forms the serpentine coil shape of series connection.
Its operation principle is: constitute the serpentine coil bundle by some sleeve type heat-pipe series connection, corrosive fume washes away the outer tube of every sleeve type heat-pipe of the mid portion that is positioned at casing, carry out heat exchange with the outer surface (comprising fin) of heat pipe tube bank, working medium in the heat pipe is vaporized, carry out heat exchange with the interior pipe feedwater of the sleeve type heat-pipe of flowing through, the working medium condensation becomes liquid again, continue said process so again and again, make flue gas heat heated feed water continuously.Because vapour in the heat pipe, the liquid two-phase is in the saturation balance state, therefore thermotube wall has good isothermal, therefore as long as regulate the temperature that the flow of feedwater just can be regulated thermotube wall of the present utility model, and the temperature that makes thermotube wall remains on the flue gas acid dew point temperature, thereby avoided the generation of acid dew piont corrosion, improved the service life of equipment, guarantee normally carrying out of production, and in case some outer tube generation seepages perhaps can produce certain influence to whole economizer parameter, but whole equipment still can move as usual, and heat pipe can singly prop up to change and repairs.
