Description

A kind of hot water circuit and the dual-purpose liquid ammonia gasifier of electrical heating
Technical field
The utility model belongs to the vaporizer apparatus technical field of denitration system of power plant part device, particularly a kind of hot water circuit and the dual-purpose liquid ammonia gasifier of electrical heating.
Background technology
The raising of country to environmental requirement in recent years, propose out of stock requirement to steam power plant's project begun newly, selective catalytic reduction (SCR) is the method for denitration relatively commonly used.Liquid ammonia gasifier becomes one of capital equipment in SCR technology.The gasifier partial pressure container of existing application and non-pressure vessel two kinds.In non-pressure vessel class, or use the liquid ammonia gasifier of electrical heating type, or use hot-water type liquid ammonia gasifier, the liquid ammonia gasifier of every type differs from one another, but all there is the limitation of oneself.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of hot water circuit and the dual-purpose liquid ammonia gasifier of electrical heating.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of hot water circuit and the dual-purpose liquid ammonia gasifier of electrical heating, comprise gasifier shell, the draining valve be communicated with enclosure interior is separately installed with from bottom to top in housing right hand external, hot water inlet, temperature takes into account hot water outlet, the liquid level gauge detecting gasifier shell internal state is installed on the left of housing, housing bottom left side wall is provided with electrically heated rod, the heating part of electrically heated rod extends to enclosure interior, at the top of housing, liquefied ammonia conduit entrance is installed, the pipeline of liquefied ammonia import extends to enclosure interior, and housing is passed after enclosure interior helical form is spiraled, ammonia pipe outlet is formed in case top, simultaneously, the liquid ammonia gasification pipeline of housing inner bottom part connects blow-off line, blow-off line is passed by case top, sewage draining exit is formed in the outer left side of housing, described liquefied ammonia inlet pipeline is provided with Pressure gauge, described ammonia outlet pipeline is provided with Pressure gauge successively, thermometer, pressure transmitter, temperature transmitter and safe diffusion device.
And, in the top outer of housing, temperature transmitter is installed.
And, in the top outer of housing, liquid level lower bound switch is also installed.
And, further water filling port is installed in the top outer of housing.
Advantage of the present utility model and good effect are:
1, the utility model device is on the basis of original water circulation or electric heating liquid ammonia gasifier, the two is combined, and the condition that device is suitable for is more extensive, and water circulation or electrical heating can also can run jointly in isolated operation, and liquid ammonia gasification is more rapid;
2, simple, the convenient operation and management of the utility model structure, flexible for installation, saving resource and safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of hot water circuit and the dual-purpose liquid ammonia gasifier of electrical heating, as shown in Figure 1, comprise gasifier shell 15, the draining valve 14 be communicated with enclosure interior is separately installed with from bottom to top in housing right hand external, hot water inlet 13, thermometer 12 and hot water outlet 11, hot water is from hot water inlet injected gas device housing, and discharged by hot water outlet form circulation in housing after, the liquid level gauge 17 detecting gasifier shell internal state is installed on the left of housing, housing bottom left side wall is provided with electrically heated rod 16, the heating part of electrically heated rod extends to enclosure interior, at the top of housing, liquefied ammonia conduit entrance 18 is installed, the pipeline of liquefied ammonia import extends to enclosure interior, and housing is passed after enclosure interior helical form is spiraled, ammonia pipe outlet 10 is formed in case top, simultaneously, the liquid ammonia gasification pipeline of housing bottom connects blow-off line, blow-off line is passed by case top, sewage draining exit 19 is formed in the outer left side of housing, described liquefied ammonia inlet pipeline is provided with the Pressure gauge 1 detecting inlet conditions, described ammonia outlet pipeline is provided with Pressure gauge 5 successively that detect Export State, thermometer 8, pressure transmitter 7, temperature transmitter 9 and safe diffusion device 6.
In concrete enforcement of the present utility model, in the top outer of housing, temperature transmitter 4 is installed.
In concrete enforcement of the present utility model, in the top outer of housing, liquid level lower bound switch 2 is also installed.
In concrete enforcement of the present utility model, in the top outer of housing, water filling port 3 is installed further, when adopting electrical heating form to water filling in housing.
Operation principle
When the utility model vaporizer apparatus runs, when needs hot water circuit gasifies, make hot water at gasifier casing Inner eycle by hot water inlet and thermal output mouth, liquefied ammonia passed in immersion coil pipe in the hot water by liquefied ammonia import and gasifies, finally from ammonia outlet out; When needs electrical heating, to electrically heated rod energising make it generate heat, allow it be in casing water heating, liquefied ammonia outputs to downstream pipe after being then vaporized by mode same as described above.
