Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the reactor structural representation with showering guilding valve according to the utility model exemplary embodiments.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, the utility model provides a kind of reactor for the synthesis of molecular sieve catalyst, comprises kettle and the cooling device that is used for cooling, and this cooling device comprises condenser coil and relief valve 4.Condenser coil is arranged on the inside of kettle 1, and condenser coil has inlet 2 and the liquid outlet 3 that extends to kettle 1 outside, on the outside that relief valve 4 is arranged on kettle 1 and the stream that the liquid outlet 3 of condenser coil links to each other.
Use the technical solution of the utility model, by with the stream that the liquid outlet of condenser coil links to each other relief valve being set in the kettle outside, can guarantee recirculated water in the condenser coil in temperature-fall period because the steam that gasification produces releases smoothly by relief valve, guaranteed the condensed water normal circulation in the condenser coil.In wherein condensed water enters condenser pipe in the kettle from water inlet pipe L1, flow out from outlet pipe L2.
According to a kind of exemplary embodiments of the present utility model, as shown in Figure 1, liquid outlet 3 places of condenser coil are provided with outlet valve 5.According to another kind of exemplary embodiments of the present utility model, the series connection of liquid outlet 3 places of condenser coil is provided with two outlet valves 5; Relief valve 4 is arranged between two outlet valves 5.Set out the normal operation that water valve 5 both can guarantee the condensation cycle water system respectively at the two ends of relief valve, help relief valve 4 to carry out pressure release again, operate more convenient.
Preferably, relief valve 4 is showering guilding valve.Showering guilding valve is arranged between the flange and outlet valve 5 of kettle 1, generally by Bolt Connection or be welded on the pipeline at liquid outlet 3 places of condenser coil.
