Abstract

The utility model discloses a CNG low pressure dewatering equipment used for natural gas feeding stations. The utility model comprises a lower pressure dehydrator and a combined type segregator, which are arranged on the front end and the back end of a compressor, respectively. The combined type segregator primarily consists of a gravity separator, a filter separator and a pipe manifold. The gravity separator and the filter separator separate the finished natural gas both coarsely and finely. In this way, foreign substance and grease are removed from the finished natural gas, and the quality of the finished gas is improved.

Description

CNG dehydration technology equipment

Technical field: the utility model relates to a kind of dehydration equipment, especially relates to a kind of dehydration technology equipment of natural gas.

Background technology: in the CNG gas station, the dehydration equipment of natural gas is essential, and the degree of depth of dehydration is wanted to closing to give birth to, and the gas water dew point after processed should reach-55 ℃; Could satisfy the requirement of natural gas as motor vehicle fuel like this, gas selling machine does not take place to ice stifled in the time of just guaranteeing to refueling simultaneously.But, use the dehydration technology device, because before it is installed in compressor, after the natural gas after the dehydration enters compressor, be subjected to the secondary pollution of interior grease of compressor and impurity, the conventional treatment mode is to use high and low splenium wetting system simultaneously, but cost is higher; Therefore, the one-tenth gas of discharging compressor is carried out post processing and become the technical barrier that must solve.

Summary of the invention: the purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and provides a kind of dehydration technology device that cooperates to use, can be to the device that becomes gas to carry out post processing, and it can remove into impurity and grease in the gas effectively, improves into the makings amount.

The purpose of this utility model is achieved in that

A kind of CNG dehydration technology equipment comprises dehydration technology device and combined type separator, wherein, and before the dehydration technology device is installed on compressor, after the combined type separator is arranged at compressor;

Wherein, described combined type separator is made up of gravity separator, filter separator, air inlet pipe, tube connector, blast pipe, blow-off pipe, blowoff valve, wherein gravity separator links to each other with air inlet pipe, its gas outlet, upper end links to each other with filter separator by tube connector, the gas outlet of filter separator links to each other with blast pipe, gravity separator also links to each other with blow-off pipe respectively with filter separator, also is provided with blowoff valve on blow-off pipe.

The utility model is because be provided with the combined type separator that cooperates the dehydration technology device to use behind compressor, utilizing its gravity separator with filter separator the finished product natural gas to be carried out crude separation separates with smart, can remove into impurity and grease in the gas, thereby improved one-tenth makings amount, avoid using simultaneously high and low splenium water device again, reduced the equipment purchasing cost.

Description of drawings: Fig. 1 is annexation figure of the present utility model;

Fig. 2 is the front view of combined type separator of the present utility model;

Fig. 3 is the vertical view of combined type separator of the present utility model.

The specific embodiment: a kind of CNG dehydration technology equipment, comprise dehydration technology device 10 and combined type separator 8, wherein, after dehydration technology device 10 is installed on compressor 9, before combined type separator 8 is arranged at compressor 9;

Wherein, described combined type separator 8 by; Gravity separator 1, filter separator 2, air inlet pipe 3, tube connector 4, blast pipe 5, blow-off pipe 6, blowoff valve 7 are formed, wherein gravity separator 1 links to each other with air inlet pipe 3, its gas outlet, upper end links to each other with filter separator 2 by tube connector 4, the gas outlet of filter separator 2 links to each other with blast pipe 5, gravity separator 1 also links to each other with blow-off pipe 6 respectively with filter separator 2, also is provided with blowoff valve 7 on blow-off pipe 6.
