Abstract

The utility model discloses a biodiesel dewatering device. The biodiesel dewatering device mainly consists of a salt filtering groove (1), a feed liquid inlet (5), a feed liquid outlet (6) and a saline water outlet (7) and is characterized in that the lower portion of the salt filtering groove (1) is provided with a blocking plate (4), and a partition plate (2) is arranged on the blocking plate (4) and inside the salt filtering groove (1). The blocking plate (4) is made of stainless steel and provided with a screen plate with certain voids. The blocking plate (4) and the partition plate (2) divides the salt filtering groove (1) into a left chamber (1a), a right chamber (1b) and a lower chamber (1c), the left chamber (1a) is intercommunicated with the lower chamber (1c), the lower chamber (1c) is intercommunicated with the right chamber (1b), and the left chamber (1a) is not intercommunicated with the right chamber (1b). Multiple layers of metal screens (3) are placed on a part of blocking plate (4) on the left chamber (1a), pore diameter of screens (3) is decreased layer by layer from top to bottom. The purposes of removing moisture of biodiesel and achieving continuous dewatering are achieved. The biodiesel dewatering device can operate continuously and has the advantages of being convenient to operate and simple in use.

Description

A kind of biofuel de-watering apparatus

Technical field

The utility model relates to a kind of de-watering apparatus, relates in particular to a kind of biofuel de-watering apparatus.

Background technology

Preparing with raw materials such as sewer oil, waste oil in the production process of biofuel product, obtain biofuel and can produce a small amount of moisture, in the use procedure that replaces petroleum diesel, can have influence on burning and the corrosion engine of biofuel in engine, the water content of water content in the USS regulation biofuel less than 0.05%, in the German standard regulation biofuel is less than 300mg/Kg, and national standard stipulates that also 2# diesel oil water content is less than 0.02%; Therefore, preparing biofuel must be through dewatering, and the utility model provides a kind of biofuel de-watering apparatus, and the moisture that contains in can biofuel obtains the lower biofuel product of water content.

Summary of the invention

The utility model purpose has been to provide a kind of method that adopts salt to consider in biofuel product last handling process, remove the moisture that reaction brings, and reaches the purpose of continuous dewatering esterase.

The utility model is realized by following scheme: a kind of biofuel de-watering apparatus, mainly formed by salt worry groove, liquor inlet, material liquid outlet, brine outlet, it is characterized in that salt considers the bottom of groove one baffle plate is arranged, on baffle plate, salt considers groove inside and establish a dividing plate.Described baffle plate, the web plate with a fixed gap of making for stainless steel.Baffle plate and dividing plate are considered groove with salt and are separated into left chamber, right chamber, three chambers of lower chambers, left chamber and lower chambers intercommunication, lower chambers and right chamber intercommunication, left chamber and the not intercommunication of right chamber.Placement of multiple layers wire mesh screen on the baffle plate of left chamber's part, successively reduce from top to bottom in the aperture of screen cloth, more preferably scheme adopts three layers of screen cloth, the upper strata screen cloth is 300 orders, middle screen cloth is 500 orders, the bottom screen cloth is 800 orders, salt is filled in the online face of upper sieve, because the salt particle diameter is larger, the upper sieve that is blocked is online, contain the oil of a small amount of water through behind the salt deposit, salt absorbs the moisture in the oil, and the salt particle diameter diminishes, and the salt deposit that diminishes falls into the screen cloth of lower floor gradually, when salt grain absorption moisture particle diameter is reduced to a certain degree, just fall into lower chambers and form salt brine solution, be deposited in salt and consider trench bottom, the biofuel that dewaters then enters pipeline by the material liquid outlet that lower chambers reaches upper chamber, salt solution is then discharged by the brine outlet of bottom, thereby can realize the purpose that dewaters.

The utility model is by increasing dividing plate and baffle plate, realize that salt and salt solution separate automatically, can in the situation of continuously operation, can directly add salt as a supplement by considering groove top at salt in the operation, salt solution can be discharged by brine outlet, thereby has purpose convenient and simple for operation.

Description of drawings

Accompanying drawing is the utility model device synoptic diagram.

Wherein, 1-salt is considered groove, 1a-left chamber, the right chamber of 1b-, 1c-lower chambers, 2-dividing plate, 3-screen cloth, 4-baffle plate, 5-liquor inlet, 6-material liquid outlet, 7-brine outlet, 8-liquidometer.

Embodiment

Such as accompanying drawing, a kind of biofuel de-watering apparatus, mainly formed by salt worry groove (1), liquor inlet (5), material liquid outlet (6), brine outlet (7), it is characterized in that salt considers the bottom of groove (1) baffle plate (4) is arranged, on baffle plate (4), salt considers groove (1) inside and establish a dividing plate (2).Described baffle plate (4), the web plate with a fixed gap of making for stainless steel.Baffle plate (4) and dividing plate (2) are considered groove (1) with salt and are separated into left chamber (1a), right chamber (1b), three chambers of lower chambers (1c), left chamber (1a) and lower chambers (1c) intercommunication, lower chambers (1c) and right chamber (1b) intercommunication, left chamber (1a) and not intercommunication of right chamber (1b).Placement of multiple layers wire mesh screen (3) on the baffle plate (4) of left chamber (1a) part, successively reduce from top to bottom in the aperture of screen cloth (3), more preferably scheme adopts three layers of screen cloth (3), upper strata screen cloth (3) is 300 orders, middle screen cloth (3) is 500 orders, bottom screen cloth (3) is 800 orders, and salt is filled in above the upper strata screen cloth (3).

Biofuel enters salt by liquor inlet (5) and considers groove (1), through left chamber (1a), arrive salt and consider the salt deposit of groove (1), contain the biofuel of a small amount of water through behind the salt deposit, moisture in the salt organism-absorbing diesel oil, the salt particle diameter diminishes, the salt deposit that diminishes falls into the screen cloth (3) of lower floor gradually, when salt grain absorption moisture particle diameter is reduced to a certain degree, just fall into lower chambers (1c), the salt solution that produces is because action of gravity, water layer is formed at the bottom that slowly is deposited to lower chambers (1c), and biofuel is on water layer, form oil reservoir and water layer in the lower chambers (1c), can consider from salt the right chamber (1b) of groove (1) except the biofuel of anhydrating, arriving material liquid outlet (6) flows out, in the operational process, by the oil reservoir in liquidometer (8) the observation lower chambers (1c) and the height of water layer, when the reaching a certain height of water layer, then opening brine outlet (7) discharges salt solution, according to the salt consumption of actual consumption, in due course, can consider groove (1) top at salt and add dry salt simultaneously.

Usually, the salt of use is generally low-cost industrial sodium-chlor, and the salt solution of discharge can continue to use after can removing moisture by evaporation, crystallization, dry process.

Can move continuously in the utility model operation, have easy to operate, use simple advantage.
