Description
Technical field
This utility model relates to technical field of chemical, particularly to steam afterheat recovery device.
Background technology
In chemical industry, during equipment work, need to consume substantial amounts of saturated vapor, these saturated vapors only have small part to be absorbed and used, and sometimes, it is wasted, it is that a steam afterheat recovery device is set under normal circumstances, carry out the recovery of waste heat, its waste-heat recovery device generally comprises casing and case lid, casing stores hot water, hot water has certain temperature, therefore can gasify as steam, so that the air pressure in casing increases, and for steam afterheat recovery device, it is not lost to ensure heat or is reduced as far as possible this purpose of loss, need certain sealing, the contradiction thus brought is exactly, sealing can then rise by an air pressure in casing, thus casing can be made to bring certain potential safety hazard, such as explode because air pressure is too high；Need to improve for this situation.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide safe and reliable steam afterheat recovery device.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of steam afterheat recovery device, including the casing in order to store hot water, in order to the discharge pipe line providing casing hot water, the lid that is placed on casing, described lid is provided with venthole portion, and described venthole portion includes the ring part towards box inside depression, is arranged in the middle of ring part in order to ventilative through hole, the block piece that is covered on through hole；Described block piece is in order to open and close described through hole.
nullBy above-mentioned setting，Lid is placed on casing，Casing is made to keep a sealing，Such that it is able to prevent the dissipation of heat，Discharge pipe line is by delivery to casing，Hot water in casing can carry out the transmission of a heat to the water pipe needing heating，On the other hand，Owing to this is arranged，Ensure that an effect of a heat-insulation and heat-preservation in casing，But a pressure in casing certainly will be improved due to the increase of steam，By a setting in pore portion，The part that can keep steam is got rid of，Reduce an air pressure in casing，And a water conservancy diversion and the process of cooling can be carried out during steam is discharged by the ring part caved in，Temperature-fall period carries out the recovery of a steam，Got rid of by through hole simultaneously，Will not get rid of the when of running into block piece，Unless the power that the pressure of air pressure is opened more than block piece，Such that it is able to open block piece，To carrying out a decompression in casing，Thus ensure its safety.
Can be preferably as concrete scheme of the present utility model: described block piece is the thin film lobe that can be driven folding by air pressure.
By above-mentioned setting, thin film lobe cost is relatively low, and convenient to carry out.
Can be preferably as concrete scheme of the present utility model: described block piece is pressure limiting valve.
By above-mentioned setting, pressure limiting valve structure is longer for service life, easy for installation.
Can be preferably as concrete scheme of the present utility model: described pressure limiting valve is high-pressure limiting valve.
By above-mentioned setting, for an air pressure in casing higher ranked when, sealing property can be suitable for for high-pressure limiting valve higher, the casing that heat-insulating property is stronger.
Can be preferably as concrete scheme of the present utility model: be provided with dividing plate in described casing, described dividing plate and the upper and lower sliding of casing arrange and casing are isolated into multiple space.
By above-mentioned setting, the setting of dividing plate, the internal water yield can be configured, consequently facilitating the heat in control chamber body.
Can be preferably as concrete scheme of the present utility model: what described dividing plate deviated from box bottom is provided with groove.
By above-mentioned setting, the setting of groove, steam can carry out the flowing of adjacent space by groove, such that it is able to guarantee the equilibrium of air pressure inside.
In sum, this utility model has the advantages that and the hot water in casing can carry out an insulation, and steam can effectively be discharged, and is that the air pressure in casing reduces pressure when have a certain size.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1:(steam afterheat recovery device), as Figure 1-3, a kind of steam afterheat recovery device, including the casing 1 in order to store hot water, in order to the discharge pipe line 2 providing casing 1 hot water, the lid 3 that is placed on casing 1, casing 1 uses rectangular configuration, and stability is higher.Seeing Fig. 1-2, lid 3 is provided with venthole portion 4, and venthole portion 4 includes inside casing 1 ring part 41 of depression, is arranged in the middle of ring part 41 in order to ventilative through hole 42, the block piece that is covered on through hole 42；Block piece is in order to open/close through hole 42.Block piece is the thin film lobe 431 that can be driven folding by air pressure.Thin film lobe 431 material can select silica gel.Block piece can be single-phase membrane valve.Being provided with dividing plate 5 in casing 1, dividing plate 5 and casing about 1 sliding arrange and casing 1 are isolated into multiple space.Dividing plate 5 deviates from bottom casing 1 while being provided with groove 6.In the present embodiment, casing 1 is isolated 4 spaces by 3 dividing plates 5, each spatially can arrange drain pipe.The structure of dividing plate 5 is as it is shown on figure 3, dividing plate 5 can be with aluminium alloy material.And it is provided with the chute for dividing plate 5 sliding on casing 1.
Embodiment 2:(steam afterheat recovery device), as shown in Figure 4, block piece is pressure limiting valve, and pressure limiting valve is high-pressure limiting valve 432.The structure of pressure limiting valve is: be provided with a diversion column in through hole 42 position of lid 3, water conservancy diversion and the cooling of steam can be carried out, simultaneously sheathed valve body on diversion column, keeps out steam pressure by a gravity of valve body self, thus ensures a heat-insulating property of inside.
