Abstract
The utility model discloses a positive and negative pressure protector of corrosive gas. The positive and negative pressure protector respectively comprises a tank body 1, a tank bottom 2, a gas inlet 3, a gas outlet 4, a water inlet pipe 5 and an emptying pipe 6, wherein the tank body is divided by a baffle by a certain volume ration; after an appropriate amount of water is injected, when the gas pressure is a value higher or lower than standard atmospheric pressure, the gas inlet is communicated with the gas outlet, so that a protection function is achieved, the whole protector has simple structure, is reliable and is convenient to install. Simultaneously, an enamel steel sheet is adopted as the material, and the protector has very good anti-corrosive performance, and is durable. Because of the advantages, the patent product has very high cost performance.
Description
Technical field
The utility model relates to a kind of positive negative pressure protector with antiseptic property.This kind protector is mainly used in to be handled biological sewage, and produces in the device of corrosive gases.This protector can make its object of protecting stably be between designed positive pressure protection threshold value (design maximum gas pressure value-standard atmospheric pressure) and the negative pressure protection threshold value (standard atmospheric pressure-design minimum air pressure value).
Background technology
The positive negative pressure protector of gas can be protected the biogas jar that biological sewage is handled, and makes the biogas jar can be because of the reasons such as obstruction of biogas air outlet, and produces excessive pressure.Also can avoid can not destroyed the main body that links to each other with it thereby protect because of excessive or too small pressure because operation such as discharging causes the adverse consequences of the flat tank body of suction that biogas jar internal pressure is too small and cause etc.
Summary of the invention
The utility model is by tank body 1, jar end 2, and inlet mouth 3, air outlet 4, water inlet pipe 5 and evacuated tube 6 are formed, and wherein tank body is separated according to certain volume ratio by a baffle plate 7, and this ratio should equal the ratio that positive pressure protection threshold value and negative pressure are protected threshold value.Simultaneously the lower edge of the inlet pipe product that exceeds the volume ratio in the numerical value of baffle plate lower edge and tank body two chambeies should equal the pairing water colunm height of desired positive pressure protection threshold value.And the lower edge of escape pipe should be greater than the pairing water colunm height of positive pressure protection threshold value to the distance of the lower edge of baffle plate.
Inlet pipe is connected with claimed object.Escape pipe is connected with atmosphere by devices such as water seals.
After this positive negative pressure protector injects suitable water; when inlet pipe and escape pipe pressure at two ends do not wait; the water of the air inlet tube chamber/tube chamber of giving vent to anger is extruded to the tube chamber of giving vent to anger/air inlet tube chamber; when pressure difference reaches positive pressure protection threshold value/negative pressure protection threshold value; the liquid level of the air inlet tube chamber/tube chamber of giving vent to anger reaches the baffle plate lower edge; at this moment two chambeies are communicated with, and gas can fully flow to low-pressure cavity from high pressure chest, thereby make pressure can not surpass designed positive pressure protection threshold value and negative pressure protection threshold value.
This protector carries out enamel and handles after having welded various piece.Its intensity is far above products such as glass reinforced plastic, and its erosion resistance is better than steel product again.
Description of drawings
Fig. 1 is a facade view of the present utility model.
Fig. 2 is a vertical view of the present utility model, has the sub-fraction tank body to be dissectd to show the baffle plate in the tank body among the figure.
Embodiment
Consult illustrated in figures 1 and 2.Tank body 1 is a thin cylinder, and end envelope has cover plate, and the other end has flange, and cover plate one side has the aperture that matches with water inlet pipe 5 diameters, and the thin cylinder both sides are respectively opened a bigger circular hole again, are used for welding inlet pipe 3 and escape pipe 4.Open a smaller aperture that matches with blow-down pipe 6 at thin cylinder again near a side of flange, generally speaking, the valve closes that blow-down pipe is external does not allow water flow out.
The baffle plate 7 of burn-oning in the cylinder inboard of tank body 1, this baffle plate will be isolated in inlet pipe 3 and escape pipe 4 in two chambeies, will make the volume ratio in two chambeies identical with the ratio of desired positive negative pressure simultaneously.Baffle plate and tank flange will have certain distance.Be tank body when installing, cover plate should make progress, flange downwards and with 2 link to each other at the bottom of the jar, baffle plate lower edge at this moment should also have one section competent distance at the bottom of jar, best baffle plate lower edge is higher than blow-down pipe.
The lower edge of inlet pipe should be higher than the lower edge of baffle plate, and the product of the volume ratio in numerical value that this exceeds and tank body two chambeies should equal the pairing water colunm height of desired positive pressure protection threshold value (1 standard atmospheric pressure=0.1 MPa=10 meter water columns).
The lower edge of escape pipe should be greater than the pairing water colunm height of positive pressure protection threshold value to the distance of the lower edge of baffle plate.
With inlet pipe 3, escape pipe 4, water inlet pipe 5, blow-down pipe 6 and baffle plate 7 weld together with tank body 1, carry out enamel then, simultaneously also will be to enamel at the bottom of the jar.
A tank body 1 that enamel is good and a jar end 2, add seal washer and connect with bolt, promptly obtains the utility model.
Claims (5)
1. positive negative pressure protector of gas with very strong corrosion resistance; comprise tank body (1), jar end (2), inlet mouth (3); air outlet (4); water inlet pipe (5), evacuated tube (6) and baffle plate (7) are formed, and baffle plate (7) is divided into two chambeies with tank body (1); one links to each other with inlet mouth (3); one links to each other with air outlet (4), but two chambeies are not to isolate fully, leaves the gap between the lower edge of baffle plate (7) and the jar end (2).
2. positive negative pressure protector according to claim 1 is characterized in that baffle plate (7) is separated tank body (1) according to certain volume ratio, and this ratio should equal the ratio of positive pressure protection threshold value and negative pressure protection threshold value.
