A kind of molten sulfur tank inner bottom part coil arrangement
Technical field
The utility model belongs to molten sulfur production technical field, relates to a kind of molten sulfur production facilities, especially relates to a kind of molten sulfur tank inner bottom part coil arrangement.
Background technology
In molten sulfur is produced, Molten sulphur all will be transported to after filtering the large tank of molten sulfur and store, and molten sulfur tank internal temperature all will lean on the coil pipe of bottom to be incubated by high-temperature steam.At present, the large pot bottom coil pipe of Molten sulphur is point two large groups conventionally, and every large group is divided into again nine groups.This nine groups coil pipe is respectively from steam pipe access steam, and the inlet/outlet pipe that coil pipe is installed is all directly to weld with main steam header, and this just causes coil pipe to leak will affect whole system.Secondly these coil pipes are to be all connected in a main steam header, once therefore leak, all coil pipes in bottom will, by Molten sulphur income, be difficult to search leak source.The large tank volume of molten sulfur is larger again, between approximately 135 ℃ to 145 ℃ of internal insulation temperature, if there is one group to leak and will affect the temperature of the large tank of this molten sulfur and decline, thereby cause within molten sulfur is set in tank body, coil pipe cannot overhaul replacing, only has cleaning tank body, produces thereby affect whole molten sulfur.
Utility model content
For addressing the above problem, the utility model provides a kind of molten sulfur tank inner bottom part coil arrangement.
The utility model is achieved by following technical solution.
A kind of molten sulfur tank inner bottom part coil arrangement, comprise main steam header, molten sulfur tank body and be placed in the some groups coil pipe in molten sulfur tank body, described group coil pipe is communicated with main steam header, and the import of described group coil pipe is provided with shutoff valve, is also provided with filter in the outlet of group's coil pipe.
On described group coil pipe, between shutoff valve and filter, be provided with drain valve.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is controlled by a shutoff valve being installed in the coil pipe import of every group, controls at filter of Increasing exports and drain valve.Once leak like this, will control confirmation by these valves, search leak source.Meanwhile, as find the leakage of a small group coil pipe, can stop using immediately, will can not affect other group's coil pipe, also can not have a greater change the holding temperature of tank body simultaneously, guaranteed that tank body temperature can normally be used.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-group coil pipe, 2-molten sulfur tank body, 3-filter, 4-drain valve, 5-shutoff valve, 6-main steam header.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of molten sulfur tank inner bottom part coil arrangement described in the utility model, comprise main steam header 6, molten sulfur tank body 2 and be placed in the some groups coil pipe 1 in molten sulfur tank body 2, described group coil pipe 1 is communicated with main steam header 6, the import of described group coil pipe 1 is provided with shutoff valve 5, is also provided with filter 3 in the outlet of group's coil pipe 1.
On described group coil pipe 1, between shutoff valve 5 and filter 3, be provided with drain valve 4.The effect of drain valve 4 is incondensable gases such as steam condensate and air of automatically getting rid of in heating device or steam pipe, and leak-off steam not.
Adopt technique scheme, in molten sulfur is produced, can control by the shutoff valve 5 and the drain valve 4 that are arranged on group's coil pipe 1 inflow point, filter by being arranged on the filter 3 that group's coil pipe 1 exports simultaneously.Once coil pipe leaks like this, will control confirmation by drain valve 4 and shutoff valve 5, searches leak source.Meanwhile, as find the 1 pipe leakage of a small group dish, can start corresponding invention and stop using immediately, will the holding temperature of molten sulfur tank body 1 not had to too much influence, thereby guaranteed that molten sulfur tank body 1 temperature can normally be used.
