Abstract
The utility model discloses a kind of secondary heat exchange water tank of water-bath stove heating system, comprise tank box, one end lower sidewall of described casing is communicated with steam inlet duct, top is communicated with cooling water inlet pipe, bottom is communicated with hot water outlet pipe, the part that described water inlet pipe is positioned at casing is communicated with spray equipment, and heat exchange water sprays in casing by described spray equipment; The front end of part and coil pipe that described air inlet pipe is positioned at casing is communicated with, and the tail end of described coil pipe is communicated with breather pipe, and described breather pipe is provided with pore towards spray equipment surface.From said structure, the secondary heat exchange water tank of water-bath stove heating system of the present utility model, high-temperature steam carries out heat exchange by coil pipe and heat exchange water after entering casing, improves the heat exchanger effectiveness of steam and heat exchange water; Low Temperature Steam after coil pipe heat exchange sprays to the heat exchange water of the low temperature of spray equipment ejection by breather pipe, not only carry out preheating to heat exchange water, and further increase the heat exchanger effectiveness of steam.
Description
Technical field
The utility model relates to heat exchange water tank field, is specifically related to a kind of secondary heat exchange water tank of water-bath stove heating system.
Background technology
GE-PG9171E type gas turbine natural gas intake air temperature lower than when 6.7 DEG C by chaser.If it is 4.0Mpa that natural gas enters factory's pressure, is so decompressed to 2.5-2.7Mpa by voltage regulating station and could supplies combustion engine use; Natural gas pressure regulating station arranges water-bath stove and uses as heated by natural gas, enter factory's natural gas temperature about 3-12 DEG C, to be declined about 6.5-7.5 DEG C by temperature-averaging after voltage regulating station decompression, the demand of safe operation can not be met, therefore, voltage regulating station water-bath stove must keep longtime running.Because water-bath stove runs for a long time, fault rate is higher and can not obtain timely defect elimination, will cause water-bath stove job insecurity, cause unit load limit operation, have a strong impact on economy and the security of unit, can not put into operation in time once water-bath stove breaks down, combustion engine can not be run.
Apply for the patent that name is called " modified water-bath stove heating system " before the applicant, solve above-mentioned technical problem.Technical staff finds, the heat exchanger effectiveness of heat exchange water tank is very crucial, once heat exchanger effectiveness is on the low side, the hot water temperature at heat exchange water tank place is lower, and the heat time for water-bath stove heating system is obviously elongated, causes production efficiency to reduce.But in use, find that the heat exchanger effectiveness of above-mentioned technical scheme is unsatisfactory, technical staff studies discovery, be cause by the heat exchange contact time of steam and heat exchange water is shorter, effect is poor.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of secondary heat exchange water tank of water-bath stove heating system is provided, high-temperature steam carries out heat exchange by the heat exchange water in coil pipe and casing after air inlet pipe enters heat exchange water tank, improves the heat exchanger effectiveness of steam and heat exchange water; Low Temperature Steam after coil pipe heat exchange sprays to the heat exchange water of the low temperature of spray equipment ejection by breather pipe, not only carry out preheating to heat exchange water, and further increase the heat exchanger effectiveness of steam; Thus ensure that the heating effect of water-bath stove.
Technical solution adopted in the utility model is:
The secondary heat exchange water tank of water-bath stove heating system, comprise tank box, one end lower sidewall of described casing is communicated with steam inlet duct, top is communicated with cooling water inlet pipe, bottom is communicated with hot water outlet pipe, the part that described water inlet pipe is positioned at casing is communicated with spray equipment, and heat exchange water sprays in casing by described spray equipment; The front end of part and coil pipe that described air inlet pipe is positioned at casing is communicated with, and the tail end of described coil pipe is communicated with breather pipe, and described breather pipe is provided with pore towards spray equipment surface.
The further improvement project of the utility model is that described coil pipe is upwards provided with multilayer successively.
The utility model further improvement project is, described breather pipe is located between coil pipe and spray equipment, and described breather pipe is connected with the tail end of coil pipe by connecting standpipe.
The utility model further improvement project is, described coil pipe is lower than the heat exchange water liquid level in casing.
The utility model further improvement project is, described pore is located at the upside of breather pipe.
The utility model further improvement project is, the downward projection of described coil pipe is "the" shape structure.
The utility model further improvement project is, the diameter of described coil pipe is less than the diameter of air inlet pipe, and described air inlet pipe is communicated with coil pipe by reducing connecting tube.
The beneficial effects of the utility model are:
