The pump that preliminary unit for treating water carries low pressure to contain solid sewage need use rinse water mechanical seal, be the sewage that contains solid particle because these pumps carry, so the backwashing manner of its mechanical seal is selected outside water feeding and washing.Pump is sealflushed water has certain requirement to water quality, and its water quality requirement is that low viscosity, temperature are lower than 80 ℃ clean liquid, and liquid internal granular mass mark must not surpass 1.5%, and filtering accuracy must not be less than 40 orders, can't pollute the medium in the pump simultaneously.The water of pump sealing at present mainly uses the low pressure deaerated water, and this part low pressure deaerated water enters into preliminary unit for treating water after using.This backwashing manner had both increased the discharge capacity of gasification waste water, had wasted the low pressure deaerated water of a large amount of high added values again, had increased production cost.
The utility model content
In view of this, the purpose of the utility model is to provide a kind of improved pump to sealflush water system, and the gasification waste water that is used to solve after the preliminary treatment is not fully utilized, and a large amount of problems of using of the low pressure deaerated water of high added value.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of improved pump is sealflushed water system; Said flushing water system is made up of first module, and said first module comprises low pressure deoxygenation water pipe, flushing water house steward and return sewage pipe, wherein; Said low pressure deoxygenation water pipe connects the flushing water house steward; Said flushing water house steward is connected to each pump flushing water inlet, and said time sewage pipe connects each pump flushing water outlet and preliminary unit for treating water respectively
Wherein, said flushing water system also comprises sewer line, and said sewer line connects outer flowing line of preliminary unit for treating water and low pressure deoxygenation water pipe respectively.
Further, also be provided with filter on the said sewer line, the filtering accuracy of said filter is greater than 40 orders.
Further, said flushing water system also comprises the Unit second parallelly connected with first module, and equipment, pipeline and annexation thereof that said Unit second is comprised are identical with first module.
Further; Said flushing water system also is provided with the connecting line that connects the first module sewer line and the second unit sewer line, and the link position of said connecting line and two sewer lines is separately positioned between the filter and low pressure deoxygenation water pipe of first module and Unit second.
Further; Said flushing water system also comprises a plurality of unit parallelly connected with first module; The equipment that said a plurality of unit comprised, pipeline and annexation thereof are identical with first module; The sewer line of said a plurality of unit links together through connecting line, said connecting line at the link position on the sewer line between filter and deoxygenation water pipe.
Visible by technique scheme; The utility model has the advantages that,, not only made full use of the gasification waste water after the preliminary treatment owing to use gasification waste water to replace low pressure deaerated water washer pump seal; And practiced thrift the low pressure deaerated water; Also reduce simultaneously the discharge capacity of gasification waste water, reduced the treatment of cyanide waste water difficulty, improved the economic benefit of producing.
Description of drawings
The improved low pressure pump that Fig. 1 provides for the utility model is sealflushed a kind of embodiment of water system;
The improved low pressure pump that Fig. 2 provides for the utility model is sealflushed the another kind of embodiment of water system.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing, but therefore the utility model does not receive any restriction.
The improved pump that Fig. 1 illustrates the utility model to be provided is sealflushed a kind of embodiment of water system; This flushing water system is made up of first module; Comprise low pressure deoxygenation water pipe 11, flushing water house steward 12 and return sewage pipe 13; Wherein, said low pressure deoxygenation water pipe 11 connects flushing water house steward 12, will be delivered among the flushing water house steward 12 from the low pressure deaerated water of battery limit (BL).Said flushing water house steward 12 is connected to the flushing water inlet of each pump 14, and for the pump sealing provides flushing water, said time sewage pipe 13 connects the flushing water outlet of each pump 14, and the sewage of collecting after the flushing is sent preliminary unit for treating water back to.
Consider that low pressure deaerated water preparation cost is higher; In order to reduce consumption to the low pressure deaerated water; The pump that the utility model provides is sealflushed water system and is also comprised sewer line 15; Said sewer line 15 is from the outer flowing line (not shown) of preliminary unit for treating water, and is connected to low pressure deoxygenation water pipe 11, substitutes the low pressure deaerated water flushing water house steward 12 is sent in the outer draining of preliminary unit for treating water.Wherein, on said sewer line 15, also be provided with filter 16, be used for further removing the solid particle of outer draining.Preferably, the filtering accuracy of said filter 16 is greater than 40 orders, to guarantee that better outer draining meets the requirement that pump is sealflushed water.Preferably, the filter on the said sewer line 15 is set to two parallel connections, wherein work, and one is subsequent use.
