Abstract
The utility model discloses a water gas graphite cooler additionally provided with a flushing spraying nozzle. The water gas graphite cooler comprises a cooler shell, an array tube bank, a gas inlet, a gas outlet, a chilled water inlet, a chilled water outlet, an observation hole and a blow-down valve. The water gas graphite cooler is characterized in that a plurality of coaxial inner-outer circle annular tubes in the same plane are arranged above an upper flange plate of the array tube bank inside the cooler shell, each annular tube is communicated with a water inlet header tube , the water inlet header tube penetrates through the shell wall of the cooler shell to be communicated with a water source tube, spraying holes which are evenly distributed around the circumference are formed in the lower edge face of each annular tube, an upper through hole and a lower through hole are formed in the position, between a lower flange plate of the array tube bank and the bottom face inside the cooler shell, of the cooler shell wall and communicated with a liquid level meter tube on the outer wall of the cooler shell, an overflow hole is formed in the position, between the lower flange plate of the array tube bank and the gas outlet, of the cooler shell wall, and a hole opening of the overflow hole is communicated with an overflow valve pipe. The water gas graphite cooler additionally provided with the flushing spraying nozzle has the advantages that spraying water arranged above the array tube bank can be opened to carry out interval water flushing on all heat exchange tubes as required according to observation, scaling on the inner walls of the heat exchange tubes is avoided, and the normal operation of a device is ensured.
Description
Technical field:
The utility model relates to the heat transmission equipment structure, particularly a kind of water-gas graphite cooler of setting up Flushing nozzle.
Background technology:
In the Ammonia Production field, in order to improve the displacement of hydrogen nitrogen compressor, the import at compressor all is provided with the heat exchange cooling device usually, thereby the temperature that is used for reducing gas medium is removed the inspiratory capacity that aqueous vapor improves compressor.
Existing water-gas graphite cooler is comprised of casing, array comb, air intake, gas outlet, chilled water water inlet, chilled water delivery port, peep hole, sewage draining exit.The array comb is provided with several corresponding array holes for two of up and down flanged plate, be fixedly connected with a vertical vertical heat exchanger tube in two corresponding apertures of up and down, two flanged plate cylindrical sealing cover types are fixed on casing inner wall, semiwater gas enters several heat exchanger tubes by the top air intake, chilled water enters by water inlet the overcurrent chamber that array comb and casing inner wall form, after implementing indirect heat exchange with semiwater gas by heat exchanger tube, discharged by delivery port.Discharged by the gas outlet, bottom after the semiwater gas heat exchange is cooling, be provided with the sewage draining exit that is communicated with blowoff valve on the inwall of bottom, gas outlet, be used for getting rid of coal dust and the sulphur powder of precipitation, peep hole is used for artificial observation.But unclean due to gas medium often, especially in the coal gas ammonia synthesis process, semiwater gas is carried sulphur powder etc. secretly after usually containing coal dust or desulfurization, effect when the equipment operation just causes the decline of heat exchanger tube fouling heat transfer effect to keep new equipment soon perhaps causes its gas channel resistance of heat transmission equipment tube sheet scale effect to rise.
Heat transfer effect in order to ensure heat transmission equipment; the chance of normally utilizing system shutdown to overhaul is opened the equipment peep hole and is carried out the manual cleaning scale removal; but processing exhausts the people and drains the treasury often like this; the one, workload is large; the 2nd, the effect that obtains is undesirable, and it is mainly due to thick and hard difficult cleaning of long operational time heat exchanger tube fouling.
If heat transmission equipment can be accomplished according to the operation monitoring data, in case find that this equipment heat transfer effect decline or resistance have the sign of increase, just can accomplish under dead ship condition, it is not being rinsed, recover the cooling effect of this equipment.
Summary of the invention:
The object of the invention is to overcome defects, a kind of water-gas graphite cooler of setting up Flushing nozzle is provided.
scheme of the present utility model is: comprise casing, the array comb, air intake, the gas outlet, the chilled water water inlet, the chilled water delivery port, peep hole, blowoff valve, it is characterized in that: several isoplanar Internal and external cycle endless tubes that are provided with coaxial inner conductor in casing above array comb upper flange plate, each endless tube respectively with the water inlet manifold pipeline connection, water inlet manifold passes casing shell wall and water source tube pipeline connection, be laid with the spray apertures of ring Zhou Junbu under each endless tube along face, at the liquid level gauge pipeline connection that is provided with on the enclosure wall between array comb lower flange plate and casing inner bottom surface on lower through-hole and casing outer wall, be provided with spout hole on the enclosure wall between array comb lower flange plate and gas outlet, spout hole aperture and an overflow valve pipeline connection.
The utility model has the advantage of: the shower water that array comb top arranges is opened during demand and all heat exchanger tubes are carried out batch (-type) water is washed away according to the observation, avoids the heat exchanger tube encrustation, improves heat transfer effect, and maintenance equipment normally moves.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment:
the utility model comprises casing, array comb 2, air intake 3, gas outlet 6, chilled water water inlet 1, chilled water delivery port 5, peep hole 4, blowoff valve 7, it is characterized in that: several isoplanar Internal and external cycle endless tubes that are provided with coaxial inner conductor in casing above array comb 2 upper flange plates, each endless tube respectively with water inlet manifold 10 pipeline connections, water inlet manifold 10 passes casing shell wall and water source tube 9 pipeline connections, be laid with the spray apertures of ring Zhou Junbu under each endless tube along face, be provided with liquid level gauge 8 pipeline connections on lower through-hole and casing outer wall on the enclosure wall between array comb 2 lower flange plates and casing inner bottom surface, be provided with spout hole on the enclosure wall between array comb 2 lower flange plates and gas outlet 6, spout hole aperture and overflow valve 11 pipeline connections.
Shower water should satisfy the covering spray to all heat exchanger tubes.
Set up liquid level gauge 8 bottom heat transmission equipment, control the inflow of flushing water (but single channel or multichannel) and the aperture of blowoff valve 7 according to the height of liquid level.Liquid level is guaranteeing to control as far as possible lower bound under the prerequisite that blowdown does not become flat, and main purpose is to prevent gas vent band liquid.When being used for maintenance, opens overfall the valve overflow.
