Abstract
The invention relates to a water-sealed valve which comprises a smoke inlet, a smoke inlet connecting pipe, a smoke outlet pipe, a shell, a water-sealed basin and a smoke outlet, wherein the smoke inlet is communicated with the shell by virtue of the smoke inlet connecting pipe; the water-sealed basin is arranged in the shell, the water-sealed basin is a container with an upward opening, the interior of the water-sealed basin is concave downwards, and the cross section of the water-sealed basin is in a shape like the Chinese character ao; the smoke outlet pipe is inserted into the shell, the low end of the smoke outlet pipe is inserted into the water-sealed basin, and the upper end of the smoke outlet pipe is communicated with the smoke outlet. When the water-sealed valve provided by the invention is placed in a chimney, the bottom space of the chimney is fully used, and the spot space is not occupied; when the water-sealed valve is placed outside the chimney, the smoke inlet can be directly connected with an inlet pipeline which is low or even close to the ground, so that the inlet pipeline is simplified, and the cost is greatly saved; for a long-sealed chimney, the sealing effect is better than that of a flue butterfly valve, and the smoke leakage risk which occurs during long-period operation of the device and the environmental hazard caused by leakage are eliminated.
Description
Technical field
The invention belongs to the gas phase media water-sealed tank technical field of petrochemical industry, relate generally to a kind of water-sealing valve.
Background technique
Along with the strict enforcement of national environmental protection regulation, in current petrochemical industry, catalytic cracking unit generally needs after exhaust heat boiler, increase the out of stock system of flue gas desulfurization.After increasing system for desulfuration and denitration, need between exhaust heat boiler and chimney, arrange cut-out equipment, flue gas and chimney are cut off and flow to system for desulfuration and denitration.Exhaust heat boiler in a lot of catalytic cracking unit system and chimney are apart from very near, heat boiler outlet and fume pipe absolute altitude very low (close proximity to ground) simultaneously, after increasing system for desulfuration and denitration, cannot arrange between exhaust heat boiler and chimney and take up an area the larger traditional water sealed tank in space, flue butterfly valve can only be set to cut off flue gas.Although arrange flue butterfly valve conserve space, its shortcoming is easy to after using a period of time occur leaking, once fume leakage will directly ring off from chimney and bring environmental protection hidden danger, affects the long-term operation of whole device, and bring unnecessary loss to enterprise.Develop a kind of novel water-sealing valve for this reason and there is realistic meaning.
Summary of the invention
The object of the invention is to propose a kind of water-sealing valve, technical problem to be solved makes its structure simple, decreases space and the land seizure of inlet pipe, thus be more suitable for practicality while ensureing excellent sealing effect.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of water-sealing valve provided by the invention, comprise smoke inlet, smoke inlet connecting tube, smoke outlet tube, housing, water seal basin, smoke outlet, this smoke inlet is communicated with housing by smoke inlet connecting tube; Arrange a water seal basin in this housing, described water seal basin is the container of opening upwards, and its inside is to lower recess, and its section is in " recessed " type; This smoke outlet tube inserts enclosure interior, and its underpart is inserted into water seal basin inside, and its upper end portion is communicated with smoke outlet.
By technique scheme, the water-sealing valve that the present invention proposes has following beneficial effect:
When 1, being positioned over chimney inside, making full use of chimney bottom space, do not take site space; When being positioned over chimney outside, smoke inlet directly can be connected with the very low inlet pipe even pasting ground of absolute altitude, simplifies inlet pipe, greatly cost-saving;
2, for long smoke seal chimney, after adopting this water-sealing valve, sealing effect is better than flue butterfly valve, the smoke spillage risk that cancellation element long-term operation exists and owing to leaking the environmental protection hidden danger that causes.
In sum, a kind of water-sealing valve of the present invention is by the structure of novelty, impel flue gas to enter in water seal valve housing by smoke inlet through smoke inlet connecting tube, the gap then formed through water seal basin and smoke outlet tube enters smoke outlet tube, and is finally flowed out by smoke outlet.During water seal, water filling in water seal basin, when the pressure that the height difference of liquid level and smoke outlet tube liquid level in water seal basin produces is greater than flue gas pressures, realizes water seal.The present invention has significant progress technically, and has obvious good effect, is really a new and innovative, progressive, practical new design.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent for allowing above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Embodiment
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of a kind of water-sealing valve proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
A kind of water-sealing valve of the present invention, comprise smoke inlet 1, smoke inlet connecting tube 2, housing 3, water seal basin 4, smoke outlet tube 5, smoke outlet 6, this smoke inlet 1 is communicated with housing 3 by smoke inlet connecting tube 2; Arrange a water seal basin 4 in this housing 3, described water seal basin 4 is the container of opening upwards, and its inside is to lower recess, and its section is in " recessed " type; It is inner that this smoke outlet tube 5 inserts housing 3, and its underpart is inserted into water seal basin 4 inside, and its upper end portion is communicated with smoke outlet 6.
Concrete, refer to Fig. 1 to Fig. 4, described smoke inlet connecting tube can be installed in bottom (shown in the embodiment of the present invention 1) or the sidepiece (shown in the embodiment of the present invention 2) of housing 3, but the present invention is not limited thereto.
