Abstract
The utility model discloses a replace device of gas chamber bottom plate lower part coal gas fast, including the gas chamber, bottom plate in the gas chamber is setting up the asphalt mortar closed layer with the gas chamber bottom periphery outside, the even interval in bottom plate center set up 20 through-holes that are the annular and arrange, set up an inversion on the bottom plate center top surface sweep a section of thick bamboo, sweep bobbin base portion outer peripheral edges with the bottom plate between set up the yellow mud sealing layer, sweep a nitrogen gas and sweep the pipe that the bobbin tip is being connected, sweep and connecting the manometer on a section of thick bamboo lateral wall. The utility model discloses can conveniently replace the residual gas in the gas chamber, be favorable to seeking fast, seal the gas chamber leakage point.
Description
Technical Field
The utility model relates to a device for rapidly replacing coal gas at the lower part of a bottom plate of a coal gas cabinet.
Background
The gas tank bottom plate corrodes, perforates and leaks gas, and forms explosive gas with the air at the lower part of the tank bottom plate, if the gas tank bottom plate is not replaced to be qualified, the explosion accident can occur when the fire operation is carried out blindly. The conventional method is that the coal gas in the cabinet is replaced by the nitrogen to be qualified, then the nitrogen in the cabinet is used for sending the nitrogen to the position below the bottom plate of the cabinet through a leakage point, and the coal gas at the lower part of the bottom plate of the cabinet is replaced, so that the replacement speed is low, and the efficiency is low.
Disclosure of Invention
An object of the utility model is to provide a replace device of gas chamber bottom plate lower part coal gas fast can conveniently replace the interior residual gas of gas chamber, is favorable to seeking fast, seals the gas chamber leakage point.
Realize the device of a quick replacement gas chamber bottom plate lower part coal gas of above-mentioned purpose, including the gas chamber, bottom plate in the gas chamber and the gas chamber bottom periphery outside are setting up the pitch mortar closed layer, the even interval in bottom plate center set up 20 through-holes that are the annular and arrange, set up an inversion on the bottom plate center top surface and sweep a section of thick bamboo, sweep bobbin base portion outer peripheral edges with the bottom plate between set up the yellow mud sealing layer, sweep a section of thick bamboo top and connect a nitrogen gas and sweep the pipe, sweep and a side wall and connecting the manometer.
When the device works, the nitrogen ball valve is slowly opened, when the lower pressure of the bottom plate of the cabinet reaches 1000Pa and is stable, personnel are arranged to detect the gas leakage condition at the asphalt mortar position at the junction of the side plate and the bottom plate of the cabinet around the cabinet body, the nitrogen purge valve is closed until the CO concentration is 0PPM, the lower pressure of the bottom plate of the cabinet is ensured to be 500Pa, and the leakage point can be safely treated by fire. After the bottom plate of the gas chamber is corroded and perforated, the gas leaks to the lower part of the bottom plate, the gas can be conveniently replaced to be qualified by adopting the structure of the utility model, and the potential safety hazard is eliminated; the coal gas at the lower part of the bottom plate is replaced for use, materials are taken nearby, and the device is simple, convenient, effective, safe, high in practicability and controllability, safe and free of risk.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
A device for quickly replacing coal gas at the lower part of a bottom plate of a coal gas cabinet is shown in figure 1 and comprises a coal gas cabinet 7, wherein an asphalt mortar sealing layer 6 is arranged on the bottom plate 5 in the coal gas cabinet 7 and the outer side of the periphery of the bottom of the coal gas cabinet, and the coal gas in the coal gas cabinet generally escapes from a certain leakage point at the asphalt mortar sealing layer 6. The bottom plate 5 center evenly at interval set up 20 be the through-hole 4 that the annular was arranged, 5 central top surfaces of bottom plate are setting up an inversion and are sweeping a section of thick bamboo 3, sweep 3 bottom outer peripheral edges and the bottom plate between set up the yellow mud sealing layer 2, sweep 3 tops of a section of thick bamboo and connect a nitrogen gas and sweep pipe 1, sweep and connect manometer 8 on 3 lateral walls of a section of thick bamboo.
